1. General information

The importance of the development of installation work

The most common modern method construction of buildings and structures is their assembly from individual elements.

The main ways to reduce the complexity of installation are to increase the factory readiness of the mounted elements, their enlargement, which leads to a decrease in the number of elements per building and an increase in the weight of the elements

Therefore, the lifting capacity of cranes increases.

Methods of lifting floors and ceilings, conveyor assembly, and block installation are becoming widespread.

They use craneless installation methods based on the use of jacks, masts, towers, and electromechanical lifts. The methods of turning, sliding, and remote control of installation are more widely used.

Installation process

Installation of structures- a complex process consisting of simple processes and operations, which can be divided into 3 groups: - transport; - preparatory; - actual installation.

Transport processes include- transportation of structures and their storage in the warehouse.

For preparatory- consolidation, strengthening and preliminary equipment of structures, provision of elements of traverses, scaffolding and devices for alignment and temporary fastening of these structures.

To direct installation- grasping of structures, lifting, installation on supports or insertion into a joint, alignment, temporary and final fastening of them to the monolith.

2. Auxiliary installation processes

Methods of transportation and acceptance of structures

Transportation from factories or warehouses is carried out:

By water transport;

By rail (any gauge);

By car;

Tractor transport;

By air transport.

The most important requirement during transportation is to avoid damage to structures, so most reinforced concrete structures transported in the designed position: trusses, beams, wall panels, etc., and the row in a horizontal position.

The strength of reinforced concrete structures upon shipment is at least 70% of the design value.

Transport dimensions must be observed.

If installation is carried out with Vehicle(“from wheels”), it is necessary that the transport enters the installation area without overload.

Vehicles are selected depending on the weight and size of the element. The utilization rate of vehicles should be the minimum, the most rational

When transporting over a distance of more than 500 km, it is more profitable to use railways. transport.

It is advantageous to transport by road - from factories in the construction area to a distance of up to 200 km.

The structures are transported according to picking lists, and the quality control department markings are applied with indelible paint in a visible place.

Structure warehouses

According to the PPR (construction plan), storage must be provided for imported structures.

At structural warehouses, structures are received and unloaded, factory markings and main dimensions are checked, and structures are sorted.

Warehouse requirement: dense base, drainage of surface water.
Steel structures are laid on logs or beams, reinforced concrete structures are laid on wooden pads.

The total warehouse area is determined by the formula:

Qi- weight of structures with equipment in tons;
g i- specific load on individual warehouse sites, taking into account aisles (columns 0.3 - 0.6, crane beams 0.5, trusses 0.06 - 0.13);
k- coefficient taking into accountauxiliary platforms 1.1 - 1.15;

Qc- average daily demand for structures;
t- supply of structures per day.

Storage of structures

In warehouses, structures with greater mass or windage are placed closer to the crane.

In order to reduce space, structures are stored in stacks.

The stacking of structures is observed, strictly ensuring the alignment of the elements.

When storing structures, they are stacked as follows::

Foundation blocks - in a stack no more than 2.6 m high, on pads and with gaskets;

Wall panels and partition panels - in cassettes or pyramids;

Wall blocks - stacked in two tiers on pads and with gaskets;

Floor slabs - in a stack no more than 2.5 m high, on pads and with gaskets;

Crossbars and columns - in a stack up to 2 m high on pads and with gaskets;

Sanitary and ventilation blocks - in a stack no more than 2 m high, on pads and with gaskets.

Passages with a width of at least 1 m are provided between the stacks.

Integrated assembly of structures

Enlarged assembly is performed when, due to the overall dimensions of the structure, it is impossible to deliver it in finished form.

More often, enlargement of structures into assembly and assembly-technological blocks is used.

Consolidation is carried out at assembly sites equipped with stands and conductors.

Assembly sites are located in the operating area of ​​assembly cranes or near warehouses, or conveyor lines are installed.

Installation of building structures when working with vehicles

With conventional technology, installation is provided from an on-site warehouse. In this case, you have to perform many operations twice.

Installation from vehicles is more productive - installation “from wheels”. With this method, prefabricated elements are delivered to the construction site in a strict technological sequence, and are supplied for installation directly from vehicles.

The entire range of work is carried out according to hourly schedules developed for each job and each shift.

This organization of work not only reduces the cost of equipment and maintenance of on-site sites, but also speeds up and reduces the cost of installation work in general.

Preparatory work for installation of building structures

Before the start of installation work, it is necessary to complete temporary structures, communications and access roads, on-site warehouses and sites for larger assembly, preparation of installation cranes and crane tracks, acceptance of structure axes and benchmarks; preparation of an installation log, acceptance of structures, preparation of structures for submission for installation.

When preparing elements for lifting, axial or other installation marks are applied to them

The same risks are identified at the site of fastening or installation of structures (on foundations, support slabs and other places).

Composite elements (beams, trusses, arches) are assembled and connected, and sometimes reinforced for lifting.

Often, assembly scaffolds, hung on the structure and lifted with it, are used at a considerable height.

Suspended installation scaffolds are mainly used for inventory purposes.

3. Basic installation processes

Delivery of structures to the installation area

The structures are supplied to the installation area different types transport (road, rail, etc.). They are served in such a way as not to deform the structure and to make it very convenient to strap and submit for installation without re-slinging.

Structures can be single (columns, beams, trusses, slabs, etc.) or fully assembled (lanterns, tunnels, etc.).

Slinging and lifting of structures

To connect structures and parts with lifting mechanisms, gripping devices are used: slings, traverses, clamps.

Slings depend on the load, its weight, installation method and must satisfy the speed and safety of slinging and unslinging.

All devices must be tested and marked with a load capacity mark.

Steel rope slings:

Endless with capped ends

Two-branch with hooks or carabiners

Four-branch

Six-branched (spider)

Traverses. For all oversized loads, the traverse is specially calculated.

The force in the terminal branch is determined by the formula:

Q- weight of the load being lifted;
m- number of branches;
α - the angle of inclination of the sling to the vertical should be no more than 50-60°. For certain forces, the cross-section of steel ropes is selected according to tables.

A rope sling wears out after 3-6 months, a chain sling - 9-12 months.

Installation and alignment of reinforced concrete structures

Before installing reinforced concrete columns, they are laid out on wooden pads near the installation site. The marks of the axes of the columns and crane beams are marked on the column.

Axle marks are also marked on the foundation.

The column is installed, as a rule, in glass-type foundations.

The column is centered along 2 mutually perpendicular axes. The foundation, if deep, is filled with cement mortar.

Verticality is checked with a plumb line or theodolite.

After installation, the distance between the bottom and top of two adjacent columns is verified with a steel thread.

The column is temporarily secured with metal wedges or a jig, and if the column is more than 9 m high, then with both.

When installing rafter beams, due to their low stability, the slings are not removed until the beam is secured.

The first beam is secured with braces, and the second beam is further secured with struts or plates, which must be welded in at least three places.

The joints between the slabs are sealed with a rigid mortar using quick-hardening cement.

The slabs can be lifted in a package.

Wall panels are attached to columns using flexible welding or bolting.

Sealing of installation joints and assemblies

The joints of assembly units are of the following types:

Monolithic on fittings outlets;

Monolithic without reinforcement;

Welding on embedded parts;

Hinged with clamps or bolts.

The joints are welded very carefully, covered with an anti-corrosion coating, and then sealed with concrete on cement.

Typically, quick-hardening cement (BTC) or Portland cement (PC) M-400 is used.

The crushed stone fraction is less than ½ of the gap thickness.

Acceptance of work on installation of prefabricated structures

They check the quality of welding, anti-corrosion protection, grouting of joints, all data is entered into a log and reports are drawn up.

Acceptance is carried out after all structural components have been secured.

Attach passports for structures, certificates for metal and electrodes, logs of installation, welding, grouting of joints and hidden work, inventory of welders’ diplomas and data from instrumental testing of structures.

Provide as-built drawings with all deviations from the project.

4. Installation methods

Mechanisms used for installation of prefabricated structures

Mounting mechanism- This is the leading machine during installation. The following mounting mechanisms are used:

Non-mobile mechanisms: masts, chevres, mast-boom, rigid cable-stayed.

Semi-free taps : tower jib cranes on a rail track, gantry cranes, portal jib cranes.

Mobile cranes: tracked, pneumatic, automobile and tractor.

Special taps: creeping, adjustable, screw, cable, telescopic towers and booms, cranes for installing suspended ceilings, etc.

Main technical characteristics for selecting cranes:
- Q - load capacity;
- L - boom radius;
- H - hook lifting height.

Methods for installing structures in the design position

The following main methods are used:

Extension, i.e. lifting structures and installing them by weight.

Sliding - the structures are enlarged to the side in advance, then they are pushed onto the finished foundation.

Rotate the structure around the hinge.

Growing up.

Conveyor installation method.

Building up- the most common method in the construction of industrial, civil buildings and engineering structures.

It consists of sequential installation of the upper structural elements on the lower ones.

The extension method can be separate or complex.

Separate method- first, all columns, crane beams are installed, then trusses, covering slabs (usually with two cranes).

Complex method- simultaneously install columns, trusses, covering slabs, walls, etc. one step of the building (most often, the integrated method ensures the fastest delivery of industrial buildings for the installation of equipment, but requires great precision).

Slide- is based on the assembly of individual structures into a large spatial block away from permanent supports. The finished structure is pushed into the design position (bridges, headframes, blast furnaces, etc.).

Method of rotating structures- structures or structures assembled from individual elements are rotated around a support into the design position (pipes, masts, columns, supports, etc.) using mounting tools.

Growing up- the sequence of construction of the structure, starting from the upper floors and ending with the first.

The topmost structures are assembled and raised, then the structures located below are added to them. This method includes the construction of buildings by raising floors and ceilings.

Sliding method- raise the upper end of the mounted structure, and pull the lower end to the foundation. Used when installing high columns, power line supports, etc.

Conveyor method- on specially equipped conveyor lines, the spatial construction and technological blocks of the coating are assembled with a high degree of readiness, and then they are installed in the design position.

The conveyor method makes it possible to reduce the labor intensity of work by more than two times. This method is economically feasible for the construction of one-story industrial buildings with an area of ​​at least 15 thousand m2

Temporary fastening of structures

When temporarily fastening structures, the process of permanent fastening is verified and completed.

Temporary fastening is not used when installing statically stable structures.

To temporarily secure structures, individual means are used (braces, struts, struts, wedges, clamps, individual conductors) and group means (conductors and other devices that allow simultaneous fastening of several statically unstable elements).

Reconciliation of elements

Alignment ensures exact compliance with the design position.

Visual alignment is carried out with sufficient accuracy of the supporting surfaces and joints. In this case, hand-held measuring instruments are used (tape measures, gauges, templates, etc.).

Instrumental alignment performed when it is difficult to ensure the accuracy of installation of elements by checking the supporting surfaces, end bases or joints of structures. It is produced by installing special mounting devices (conductors, frame-hinged indicators, etc.).

Instrumental reconciliation is the most common type of verification. In this case, theodolites, levels, laser instruments and devices, etc. are used.

Calibration-free installation widely used in the installation of prefabricated metal structures.

Its main condition is the use of structures with a high class of accuracy of geometric dimensions in installation joints, which allows the installation of structures without the need for height and vertical alignment.

IN Lately started using automatic reconciliation , involving installation using automatic devices.

Selecting taps

Based on the installation characteristics, structures and conditions of the construction site, the necessary technical parameters of the cranes are established; Based on the volume of work and installation duration tasks, the required number of cranes is determined, then the technical and economic indicators are compared and the optimal option is selected.

The designs are characterized:

Q m - installation weight (the weight of the structure itself and the devices lifted with it);

H m - installation height (lifting height of the crane hook);

L m - the required reach of the crane boom.

The installation height is determined by the formula:

H m = h 1 + h 2 + h 3 + h 4 + 1.5 m

h 1- mark from the crane parking level to the support on which the element is installed, in meters;
h 2- the height of the element lifting above the support is 0.5-1 meter;
h 3- height of the installed element, in meters;
h 4- height of the load-handling device above the installed element, in meters;
1.5 m - height from the crane hook to the axis of the crane head.

Boom radius L m - depends on the position of the mounted elements.

Elements that are accessible (columns, trusses, crane beams, etc.) can be mounted with the smallest boom radius, i.e. make the most efficient use of the lifting capacity and lifting height of the crane hook.

In this case, the suitability of the crane parameters is checked using the load capacity curves.

The required load capacity is found on the curve, and its correspondence with the installation height is determined using the lift height scale.

The boom reach of self-propelled cranes for installing elements such as covering slabs, lantern frames, panels, etc., access to which is blocked by previously installed structures, is determined graphically.

For a graphical definition, on any scale, draw out the structure of the erected structure, all locations of the elements to be lifted and the axis of the crane boom, which must pass through 2 points: A - at a distance of 1.5 meters from the extreme point of the installed structure, B - at a height of N m.

Above the crane parking level, at a height of 1.5 meters, draw a line N - N, which passes through the crane boom hinge.

The boom axis is brought to this line and the distance “L” corresponding to the position of the crane’s rotation axis is set aside to the right of their intersection point. L and h are taken equal to 1.5 meters.

By lengthening the boom, you can reduce its reach and bring the crane closer to the structure (see dotted line).

The boom radius L m is measured from the axis of installation of the structure to the axis of rotation of the crane.

Based on the value of N m and L m, they are found from the Q m graphs.

The required number of taps is calculated by the formula:

Q- volume of work, in tons or m3;
P e- average operational productivity of the crane per shift, in tons or m3.
T- duration of installation (shift).

When a faucet has been selected according to its characteristics, its efficiency is determined using the formula:

Laughter- cost per unit of mechanized work;
With m.cm.- cost of machine shift;
P ex. - replaceable crane performance;
C P - the cost of preparatory and auxiliary work;
V - volume of work performed in tons.

5. Installation of foundation structures

Installation reinforced concrete foundations in industrial buildings

The quality and accuracy of the above-ground part largely depends on the accuracy of the installation of the foundations. Before installation begins, the foundations must be prepared, the layout of the building must be laid out, and the axles must be well secured.

It is necessary that the upper edge of the foundation has a mark of 0.15 meters. This makes it possible to complete a zero cycle. (As a rule, self-propelled jib cranes are used for installation).

The foundations are laid out in the installation area.

Install the stove, then the glass itself.

After installation, they monolith and, if necessary, weld each foundation and check it instrumentally (installation of column sills is very labor-intensive and imprecise, so it is rarely used).

Foundations for metal columns can be prefabricated (especially for masts), or monolithic, in which anchor bolts are installed, slabs are put on the bolts, they are aligned with a level, they are added, then the columns are mounted (non-alignment installation)

Installation strip foundations from large blocks

The most common type of foundation- tape. They are constructed from prefabricated reinforced concrete foundation pads and prefabricated concrete foundation wall blocks.

In most cases, such buildings have a basement or basement floor.

If not groundwater, foundation blocks with voids are used.

If the soil has good bearing capacity, foundation pads are laid every 40 cm, i.e. discontinuous foundations.

Foundations are usually installed using self-propelled cranes. Installation begins with the installation of two lighthouse pillow blocks, which are verified and installed in accordance with the project

Lighthouse blocks are installed at a distance of no more than 20 m from each other.

Corner blocks and blocks of wall intersections are always lighthouse.

Special mounting holes are left for passing pipelines.

The openings of the pits can be filled only after the floor slabs have been installed. You can fill the foundation without overlapping if a special calculation is made.

After installation is completed, a leveling layer is made from a 1:3 cement mortar, which also serves as a preparation for waterproofing.

Installation of foundations and basement walls from reinforced concrete panels

The installation of panels begins with a support panel in the end row, then there is a row panel, then a cross panel, etc.

After the panels have been assembled, they are boiled, the embedded parts are covered with an anti-corrosion coating, the seam is sealed, and the walls are waterproofed.

6. Installation of industrial building structures

Sequence and installation diagrams of reinforced concrete structures

Industrial buildings, as a rule, are structures that are significant in plan.

Some of the structures are large in weight and length. These elements are installed in parts, very often two cranes are used, and the installation of building structures is often combined with the installation of equipment.

The construction of foundations for equipment is carried out in two ways: open method when the foundations for the equipment and the building frame are installed simultaneously; closed method, when foundations for equipment are installed in a finished building.

The installation of buildings is usually carried out using sections. Their size can be such that they are equal in size and coincide with the division of the building into sections or temperature blocks.

There are three schemes for the sequence of installation of prefabricated elements:

Separate;

Comprehensive;

Mixed.

Separate scheme- install identical elements at once along the entire length of the grip: all columns, crane beams, trusses, covering slabs. With this scheme, the cranes operate more rhythmically, and the same equipment is used.

Complex scheme- install all elements of one step of the building, check and secure them. This scheme requires greater precision, but the equipment is ready for installation immediately.

Mixed scheme- occurs most often. First, the installation of columns and crane beams is carried out, then trusses and covering slabs.

With this method there is a distinction longitudinal installation: each span is mounted separately (this is beneficial in rolling production).

Cross mounting - With this method, it is very important to choose the correct direction of movement of the cranes for installation (this is beneficial in converter production).

Column installation options:

You need to choose the number of parking lots, the length of the crane passage, the installation time, but you need to take into account temporary roads.

Before the installation of the trusses begins, it is necessary that the concrete for the embedding of the columns reaches 70% strength.

During continuous installation of building frames, the following work technology schemes may be used::

Installation of all structures, incl. foundations, with one crane;

Installation of foundations with one crane, and above-ground structures with another crane (most often);

Installation of each structure with a separate crane, selected taking into account the characteristics of prefabricated structures.

Installation of the wall fence is usually carried out using another crane.

Trusses and lanterns are usually mounted together.

The connections and covering slabs are mounted using a jib.

The connections are strengthened before installation.

The slabs are lifted in batches, this increases the performance of the crane.

Installation of medium and heavy industrial buildings

Industrial buildings, as a rule, have spans from 18 to 36 meters, heights from 8 to 50 meters, and have cranes with a lifting capacity of 5 to 220 tons.

They are often designed from mixed structures: metal and reinforced concrete, weighing up to 100 tons.

As a rule, such structures are delivered directly to the installation area, and the assembly of the elements is carried out under the installation crane, but without changing the reach of the boom or the travel of the crane.

These buildings are divided into medium and heavy types.

Medium type span width from 18 to 30 meters, height from 8 to 30 meters, crane lifting capacity from 5 up to 75 tons.

These are machine-building shops, rolling shops, foundries, forges, etc.

They are mounted, as a rule, by pneumatic, crawler, tower and rarely railway cranes. taps.

Heavy type buildings - all others that have at least one of the parameters greater. These are open-hearth, converter shops, etc.

Mounted with heavy crawler and tower cranes.

7. Installation of arched vaulted and spatial structures

Hangars, warehouses, train stations, covered markets, arenas, etc. require large areas and, accordingly, large coverings without intermediate supports.

The most common coverings are frames, arches, dome coverings, and shells.

Enlarged coverings are made, as a rule, from reinforced concrete and steel, less often wooden.

Frame covering structuresmounted in 3 ways:

With assembly from enlarged mounting elements in the design position on temporary supports.

With the assembly of crossbars, frames on the design axis and lifting them in the design
position of cranes or masts.

With the assembly of crossbars outside the building, lifting them to the design height and transporting them to the design axis on towers or portals.

Installation spatial structure performed using lifts and hydraulic jacks after complete assembly on the design axis.

In all cases, a special work plan for the installation of structures is drawn up.

Installation of three-hinged arches is carried out in almost the same way as frame structures:

When mounted on a temporary support, movable bridges are used.

Installation of arches using the sliding method.

Installation dome coating structures.

These are covered premises of exhibition pavilions, circuses, gyms, churches, markets, etc.:

Using temporary support.

Installation using mobile template trusses using a crane.

Installation hanging (suspended) coatingsSuspended cranes began to be used very often.

Saddle-shaped cover design.

The sag can reach up to 5 meters.

High-strength steel cables are installed. The slabs are mounted onto the cable stays by a crane and cemented into place.

Installation of coatings for one-story industrial buildings or cultural and domestic purposes from prefabricated reinforced concrete shells of double curvature can be performed in two ways:

Immediately in the design position;

Lifting the shell assembled at the bottom using jacks.

8. Installation of special structures

Installation of steel tanks(blast furnaces, air heaters, tanks, gas tanks, etc.). Steel sheets with a thickness of 3 - 80 mm.

Installation is carried out in two ways- sheet and from roll blanks.

Sheet assembly- made from individual sheets or enlarged into cards, shells and belts of 2-3 sheets.

Installation of the tank bottom is carried out from the middle. First, the horizontal seams are welded, and then the vertical ones.

The walls are assembled from the bottom up.The sheet is placed in a vertical position on a shelf. After welding, the seams are checked for leaks using x-rays, ultrasound or kerosene.

Installation of tanks from roll blanks- the bottom and body are welded at the factory and rolled into rolls.

The bottom of the two halves is overlap welded.

Then the housing roll is placed in a vertical position and unfolded, grabbing it to a special stand.

Grain silos are assembled from 8-sided silos weighing up to 10 tons, cement silos with a diameter of 6, 9, 12 meters weighing 12 - 25 tons. With a diameter of 9 - 12 meters, they are assembled from segments, and 6-meter ones from rings.

Installation of cooling towers. To cool circulating water, tower-type cooling towers are built.

The reservoir for collecting water is prefabricated monolithic (less often monolithic).

J.b. The cooling tower frame is mounted in tiers by a crawler crane.

The walls - a metal frame with slate are assembled into cards at the bottom - are mounted using the turning method.

Installation of reinforced concrete tanks for liquids. In tanks made of prefabricated reinforced concrete, walls, columns, beams and coating slabs are installed, and the bottom is made monolithic with a tooth for the outer panels.

Glass-type foundations are placed on the finished monolithic bottom using mortar.

Columns are installed simultaneously with beams.

The covering is made of ribbed slabs laid on beams. When the concrete at the joints of the wall panels reaches 70% of the design strength, reinforcement is wound from high-strength steel wire and external gunite is applied to the walls.

9. Installation of multi-storey civil and industrial buildings

Installation of multi-storey industrial buildings

Installation is carried out using crawler, tower or gantry cranes. If they are mounted with two cranes, then to ensure safe operation it is necessary that the action areas of the booms do not touch each other, or limit the rotation of the boom.

During installation, a floor-by-floor check with tools or templates is required. Installation of foundations and basements is carried out as in one-story buildings.

The above-ground part is installed after inspection and delivery according to the zero mark certificate

When installing the above-ground part, the building is divided into sections in plan, and vertically into tiers (the height of the tier depends on the height of the columns of the 1st - 2nd floor).

If the columns are one-story, then the columns are installed first, then the purlins, crossbars and covering slabs.

If it is 2-storey, then first the columns, then the crossbars and floor slabs of one floor of the building, then the other.

Installation of the next tier can be done after the lower tier has been completely secured and the monolith has reached at least 50% strength.

Columns are installed using a group conductor for 4-6 columns. When the columns are boiled, the crossbars are installed and also boiled.

Then the slabs are assembled (first the spacer slabs between the columns, and then all the rest).

It is necessary to strictly ensure that the slabs are welded to the crossbars; the rigidity of the building frame depends on this.

The seams between the slabs are monolithic.

Installation of large-panel frameless houses

The installation sequence is determined by the need for the fastest formation of stable cells.

Installation is carried out using grips, as a rule, a grip is a section.

The installation of sections begins with the installation of the elevator shaft, staircase and facade panels.

First, panels are installed that are more distant from the crane, then panels of internal transverse walls and internal longitudinal walls.

Wall panels are installed on cement mortar.

Before fixing the panel, it is carefully aligned with a plumb line, a template, and then welded.

For temporary fastening of panels, rigid sliding struts, ties, and clamps are used.

Floor slabs are laid from the beginning of the house section and end at the end of the section.

The welding areas of all metal parts are galvanized or sprayed with aluminum.

Balcony slabs are temporarily secured using racks - struts.

Installation of frame-panel houses

Frame-panel houses are assembled in tiers. The tier is equal to 2 floors, because The height of the columns is two floors. The building is divided into occupations - the occupation section.

The main requirement is to ensure the rigidity and stability of the frame during and after installation.

Therefore, installation is carried out in blocks (it consists of 6 columns, beams and floor slabs for 2 floors).

After welding and cast-in-place, wall and partition panels are mounted on the assembled block.

The columns are mounted using a group conductor for 6 pieces.

For stability, connections are provided; after welding the structure, the conductor is removed.

Wall panels are installed first at corner and wall panels, they are beacons

The final alignment of the panels is done when the entire block is mounted, then the joints are sealed.

If the external walls are load-bearing, then the columns are 1 floor high, and the installation technology changes.

First, columns and beams are installed, then external walls, then partitions, floor slabs.

Installation of buildings from large blocks

A block weighing up to 5 tons can be mounted by any crane, from truck to tower.

It is better to have a truck crane to unload blocks. It is more efficient to install large-block houses from wheels on an hourly schedule.

First, corner blocks are installed, then blocks at the intersections of internal walls are lighthouse blocks.

If the distance between the lighthouse blocks is more than 20 meters, then an intermediate block is installed. The blocks are installed according to the level. Be especially careful so that the solution does not get into the blocks with channels, otherwise it will be difficult to clean later.

Wall cutting can be two rows, three or four rows

Installation of houses from volumetric elements

The buildings are assembled on the site from volumetric elements, a block - a room, a block - an apartment, fully finished and equipped with engineering equipment in the factory. They are delivered to the installation site by vehicles with specially equipped platforms.

The zero cycle device is the same as for large-panel buildings.

They are mounted, as a rule, with a gantry crane Q = 30 tons. Less often, with a tower or jib crane.

The building is assembled floor by floor. Mounted from wheels and very rarely from stock.

The seams are caulked with cement and embroidered with cement mortar.

In addition, the blocks are welded together. Waterproofing is installed in the horizontal seams between the blocks.

Vertical joints are filled with heat and sound insulating bags.

One element is installed in 1-1.2 hours. The whole building is five floors, 45 apartments - 15 work shifts.

The fundamental difference between volumetric block construction is high factory readiness

Installation of parts by lifting floors and floors

Upon completion of the zero cycle work, columns are installed to the full height or only the first tier.

Then the floor slabs are concreted at the zero level, and then raised to the design level along with the assembled floor or just the floors.

Hydraulic jacks are installed on the head of the columns.

The idea of ​​raising floors was expressed in the late 40s by the Frenchman Lofargue

In 1951, a successful experiment took place in the USA. This method is now widely used throughout the world, especially in seismic areas and cramped building sites.

This method has been developing in the USSR since 1959. 4 were mounted in Leningrad storey house, and then built a 5-story and 14-story building. A 16-story building was built in Yerevan.

Buildings erected using the method of raising floors have the following advantages:

They can have any shape in plan, as well as any width, because... are not limited by the reach of the tower crane boom.

The ceilings have a low construction height.

Construction is possible in cramped conditions and in areas with difficult terrain.

The floors have great rigidity and fire resistance.

10. Features of installation of metal structures

From the standpoint of the installation process, metal structures have a number of specific features.

They, as a rule, have large geometric dimensions, which very often conflict with the rigid parameters of both railway and road transport.

This does not make it possible to increase the degree of factory readiness of mounting blocks. They have to be enlarged before installation.

Flexibility steel structures significantly more reinforced concrete during installation. Therefore, you must always start with tie columns or blocks.

And this must be taken into account when developing CM and CMD, as well as taking into account the technology for transporting structures.

Joints of metal structures are able to withstand installation and permanent loads relatively quickly compared to reinforced concrete ones, which makes it possible to significantly increase the pace of installation work

At the same time, we must not forget about the stability of structures. Therefore, extended or high-rise metal structures are divided into installation sections in accordance with expansion joints and spans; installation work is carried out using an integrated or combined method (a differentiated method is rarely used).

11. Features of installation of prefabricated structures in winter conditions

General requirements

The advantage of installation work is that the prefabricated elements are ready and only the joints need to be sealed.

General requirements for sealing joints in winter:

It is necessary to strive to have as few joints as possible;

Concrete must gain 100% strength before subsequent installation;

The joints are made of metal, which is justified, but they need to be protected from corrosion;

To monolith, you need to heat the joint;

To mount a higher floor, you need to completely monolith the lower one;

Crane beams are monolithic in the warm season or indoors;

Joints in multi-storey buildings can be monolithic after the wall panels are installed;

Concrete is used with BTC or Portland cement M400, rarely with aluminous cement.

There should be no more than 450 kg/m³ of cement in concrete, otherwise there will be cracks. W/C 0.4-0.5, laid at a joint temperature of + 20º C. The strength of the concrete in the embedment should be 1.5 - 2 times higher than the strength of the elements being embedded

Sealing joints of frame buildings

The joint surfaces are cleared of snow and ice. The joint is heated with hot water.

The water is heated to a temperature of +45º C. The water is pumped out of the nest.

Then the dry mortar mixture is laid down, and concrete is placed on top and covered with a tarpaulin.

Column joints (heated by warm formwork or induction) can be monolithic with the addition of sodium nitrite or potash. Unreinforced joints - with chloride salts.

The grouting of interfaces in large-panel buildings must be carried out especially carefully.

Protection of embedded parts from corrosion

Embedded parts and connections in winter time particularly susceptible to corrosion.

Most reliable protection- application of metal coatings (zinc, aluminum).

The mortgages are galvanized, then the seams are tightly cast.

If you do not protect embedded parts with a thickness of 6-8 mm, then corrosion eats them at 0.1 - 0.2 mm per year. Protection with varnishes, paints, and enamels has no effect.

Features of the construction of large-panel buildings in winter conditions

To avoid deformation of buildings, reinforcement of corners and junctions of internal and external walls is used.

Along the contour of the building at the floor level above the 1st and 4th floors, reinforcement is carried out with 8 mm wire, and they are reinforced using electric heating.

Concrete is used grade 100, with Portland cement grade 400 with sodium nitrite.

12. Quality control of installation of structures

The basic requirements for the production and acceptance of installation work are formulated in SNiP 3.03.01-87 “Load-bearing and enclosing structures”.
The quality of installation of structures is checked using geodetic instruments and templates.

When installing foundations, coincidence of seams between foundation blocks and foundation pillows. Offset in adjacent rows by ¼ block length.

For basement walls made of concrete blocks, the thickness of the joints is 15 mm, but not more than 20 and not less than 10 mm. The deviation of the rows from the horizontal over a length of 10 m is 15 mm, from the vertical per floor no more than 10 mm. The deviation of the marks of the supporting surfaces does not exceed 20 mm.

In large-panel buildings, the displacement of the axes of wall panels and partitions in the lower section relative to the alignment axes should not exceed 8 mm, in the upper section - 10 mm.

The width of vertical and horizontal joints of external wall panels should be within 10 - 20 mm.

For floor panels up to 4 m long, a deviation from the design support value of no more than 8 mm is allowed, for longer slabs - up to 10 mm.

In frame-panel buildings, including one-story industrial buildings, the stability of structures during installation and the reliability of their operation depend on compliance with the technological sequence of assembly of elements, the quality of their installation and fastening, including sealing of joints

The brands of solutions used when installing bed structures must correspond to those specified in the project.

It is not allowed to use a solution whose setting process has already begun, or to restore its plasticity by adding water.

In single- and multi-story frame buildings made of steel structures, maximum deviations of the actual position of mounted structures should not exceed permissible values.

Deviation of column support marks from the design ones and displacement of the column axes from the alignment axes - 5 mm; deviation of the column axes from the vertical in the upper section for a column length of up to 8 m is 10 mm, for a length exceeding 15 mm.

It is allowed to shift trusses and beams from the axes of columns of one-story buildings up to 15 mm, crossbars and beams in multi-story buildings - no more than 8 mm.

The following standards have been established for crane beams: the displacement of the crane beam axis from the longitudinal alignment axis is 5 mm, the displacement of the support rib from the column axis is no more than 20 mm.

Standards and rules are established General requirements to the organization of construction production during the construction of new, as well as expansion and reconstruction of existing facilities. These standards must be observed by all participants in the construction of facilities

When we talk about the construction, reconstruction or repair of any construction projects, we are always talking about a whole range of activities. The production procedure is regulated by rules, regulations and requirements, which will lead to the desired result in the form of a strong, reliable and aesthetic building. What are construction and installation works? They are a separate area of ​​construction, which cannot be avoided when carrying out capital projects. repair work indoors, as well as during the construction of new buildings.

The essence and features of construction and installation work

The definition of construction and installation work is a very broad concept. By it is meant operational process, including multidirectional actions that differ from each other according to many criteria. Differences may be in deadlines, the essence of the process, methods and algorithm of construction or installation operations. The definition of construction and installation work (CEM) is a set of actions aimed at the construction, reconstruction or repair of structures and other objects. As a rule, it is difficult for one company to complete the entire operational cycle of activities. Their scale is colossal, and it is often impossible to cover all the assigned tasks. Today there are many companies on the market: some carry out the entire operational process, others carry out installation or construction work. The choice of a professional with a narrow specialization determines the quality of the work. Often, in order to save money, many owners of private construction projects perform some types of work with their own hands. To achieve the desired result, it is important to understand the operational process, its sequence, study the manual and rules for performing construction or installation operations.

Today there are three main directions:

1. General construction sector.
2. The sphere of transport and loading and unloading operations.
3. Specialized type of work.

Each of the main areas is regulated by production rules, safety standards during implementation, technological maps, SNiP rules, state standards, and ENiR calculation rules.

The essence of general construction activities

The category of general construction activities is the most extensive. The concept of work of this type contains several important stages on which the construction of buildings for any purpose depends. The entire operational process, as they say, from A to Z, must comply with standards and rules. The list of multidisciplinary events looks like this:

1. A set of geodetic processes carried out on construction sites:

• control of geodetic parameters, calculations, characteristics;
• carrying out geodetic surveying.

1. Preparatory activities that include:

• cleaning the area, preparing for the start of construction processes;
• if necessary, dismantling buildings or structures;
• construction of temporary structures to carry out the main complex of construction activities.

1. Excavation. The list of such activities involves the following:

• production of excavations, arrangement of vertical layouts;
• production of trenches and digging pits for construction;
• working with soil, compacting it, arranging a “soil cushion”;
• carrying out excavation work in non-standard conditions (during subsidence of heaving soil).

Important! Excavation work involves the implementation of the entire complex of activities exclusively by professionals. The service life of the building and its reliability, regardless of its functional purpose, depend on the quality of such work.

In addition to the preparatory complex, general construction work also includes processes that complete the main stages of construction:

1. Stone work is a special type of activity, which represents a set of works on the construction and strengthening of building walls, supports and pillars. Stone work also includes bricklaying and decorative finishing of facades. All this can be done with your own hands, but you need to know the rules, principles and construction technologies. Having mastered the knowledge and following all the rules, you can do the work yourself, saving significantly, but without compromising the quality of the building.
2. The list of concrete and reinforced concrete works includes:

• complex of reinforcement and formwork works;
• welding and installation operations;
• arrangement of monolithic structures.

1. Roofing. This type of activity is classified as installation work. The roof crowns any structure and serves as protection against heat loss and exposure to precipitation. The degree of comfort and safety of living in the house depends on the quality of execution. The subgroup of roofing activities includes:

• installation of roofs from any materials (roll, piece, metal and sheet);
• arrangement of roofing pie (steam and water protection of structures);
• welding and installation work on the construction of frames;
• installation of windows of any type (including attic windows);
• arrangement of drainage.

1. Finishing work. This type of operation can be performed even by a beginner in the construction business, the main thing is to know the rules and carry out quality control at every stage. Finishing works include:

• a set of facade measures (decorative and protective cladding of the facades of buildings for any purpose);
• welding and installation production of frames of internal metal partitions, laying bricks, plasterboard;
• painting and plastering complex, glazing production - aimed at decorative finishing of elements, protective cladding, glazing of structures.

1. Complex of insulation works. Its essence is to create maximum comfort indoors, minimizing external negative impact external environment, enhancing the properties of strength and practicality. This also includes insulation using bituminous materials, reinforcing shells, slabs or bulk materials.

The list of general construction works includes, among other things, low-voltage work. They involve the installation of cables and wires whose voltage does not exceed 25 volts. The complex is necessary for installing telephones in a building and organizing systems fire safety, installation of alarms and security systems of any type.

Direction of civil works

To understand what civil works are, you need to know the very essence of construction. It is this area of ​​activity that holds the title of one of the oldest and most revered areas. Undoubtedly, production and technical progress is moving forward, the production of new materials has been established, effective developments and innovative solutions are appearing. This development allows for the construction of reliable and durable buildings, and the aesthetics of each completed project are excellent. There are two main branches of construction: capital and non-capital. The first type includes all buildings and structures that represent the category of real estate. This means that every building is connected to the ground through the laying of a foundation. There are several types of capital construction projects:

• All types of buildings that are equipped with underground structures (plinths, foundations), as well as a ground part. This type of building system includes network engineering, organization of water supply and sewerage systems, ventilation systems. The general functional purpose of the category is the residence and life of people.
• All types of structures that are flat systems and bearing structures with aboveground and underground parts. Such facilities are usually intended for the movement of people or goods, the implementation of any production processes, as well as the storage of products. Examples of this type of structure are dams, bridge structures, and all types of roads (motorway, railway).
• All objects are representatives of the unfinished construction category. These include buildings that, for a number of reasons, have not been approved for operation or their construction has been suspended. Until the operational process is completed, proper control and approval for operation have not been carried out, buildings are called typical objects of unfinished construction.

Objects that are representatives of the non-capital construction category include all structures of a temporary nature. These are trade kiosks, household facilities (sheds, storerooms, barns), pavilions or hangars with a collapsible structure.

Types of objects and their classification

The purpose of the constructed objects can be very different and perform different functions. It can be production facilities, residential buildings, structures for agricultural needs. In accordance with functional purpose construction is divided into several types:

1. The field of civil engineering. These are buildings of any number of storeys for residence or public and commercial activities (administrative, commercial, municipal or office).
2. Sphere of industrial construction. This category includes all work on the construction of workshops, factories or factories, any production areas, plants.
3. The field of agricultural construction is the construction of structures for livestock farms or agriculture. This also includes the construction of veterinary clinics, greenhouses, and agricultural structures.
4. Transport construction. The category includes the construction of bridges, tunnels, and highways.
5. Hydraulic engineering. The scope involves the construction of reservoirs, dams or canals.
6. Military sphere. Involves the construction of any construction projects for military and defense purposes.

Important! All types of construction and installation activities are regulated by the norms and regulations of SNiP, GOST, as well as ENiR standards.

A construction project is, in its own way, an end product. All costs of its production must be strictly calculated. For this purpose, there is an ENiR system, which is a complex of pricing calculations and estimated standardization. Budgeting a project without knowledge of ENiR standards is impossible. All stages must be taken into account: construction design, concluding contracts for work, costs for the purchase of building materials, payment of labor to employees.

Control levers

In order for a structure to meet all technical standards and meet the highest safety class, control is necessary. We will talk about supervision of construction and installation work, which is essentially a set of inspection activities. the main objective– not to punish or apply fines, but to ensure strict compliance with all technical specifications project. Technical control consists of the following stages:

1. Financial check. Control and adjustment of methods are applied, the goal is to minimize financial losses and risks. Assessment and control takes place at all stages of construction. The oversight mechanism is especially important when money from outside investors is used to construct a building.
2. Checking compliance with deadlines. At each stage, a certificate of completion of work is issued, in accordance with which quality control is monitored.
3. Control over the use of building materials. Production and construction technologies require the use of high-quality building materials with a set of required properties.

Important! Technical control is regulated by standards and documentation. The main controls of supervision include SNiP rules, ENiR standards, and compliance with established GOST standards.

In addition to monitoring the quality of work, technical supervision allows you to solve the following problems:

• To prevent an unreasonable increase in costs for construction and installation work and to identify discrepancies between expenses and the agreed estimate.
• Logging control and technical documentation. Each operational process and the technology for its implementation are confirmed by an act. Transparency of data allows timely detection of errors, deviations from SNiP standards or ENiR calculation rules.
• Supervision and identification of violations during the construction of structures, errors in parameters, non-compliance with calculations.
• Solving problems with soil shrinkage, cracks, deformation and other problems with violation of technical conditions.

Who supervises? These are professionally trained people with valuable construction experience. The controller of construction and installation works can be design engineers and specialists in general construction work. Their main tasks are monitoring compliance with process technology, conducting intermediate acceptance of work, and participating in engineering inspections. As a result of the control, an inspection report is signed, which indicates the inaccuracies and the period within which the errors must be eliminated. During the construction and installation work, a technical supervision log is filled out; its maintenance is an integral part of the construction process. Upon completion of construction, a certificate of completion of work is submitted.

Architectural supervision as a type of control over construction and installation works

In addition to technical supervision, one of the auxiliary levers for optimizing construction production and quality control at all its stages is designer supervision. The construction industry is very specific; it has rules that must be followed strictly. This is a guarantee of construction success and delivery of a project of proper quality on time.

• Control can be exercised by management, legal and individuals on the basis of a signed cooperation agreement.
• It includes a number of functions for conducting intermediate checks for the purpose of quality control and identifying errors in construction technology.
• Supervision of compliance with all aspects of safety and compliance with environmental standards is carried out.
• Management can make proposals to improve the quality and optimize construction and installation work at the site.

The contract may also include any clauses established on an individual basis, depending on the functional and operational focus of the construction project.

Activation of work during construction

The finished project is a complete complex. To ensure compliance with the established standards of SNiP, ENiR and other regulatory standards, a certificate is issued. It is also necessary to draw up a hidden work report. What it is? Hidden work is “hidden” behind subsequent construction or already completed activities. Compliance with quality standards is confirmed by an act drawn up in accordance with all the rules. The list of hidden works includes laying the foundation, land surveys, and fastening wall structures. The quality of each of the above-mentioned hidden works, compliance with SNiP and other standards is confirmed by the act.

Advice! For each object, a list of hidden installation and construction works is prepared at the design stage. Such an act is rarely completed at the stage of finishing of buildings.

Each stage is subject to separate control, even if simple repairs are being made to the apartment (priming, finishing, insulation or installation of communications, and much more). An act or form confirming the operational process must be drawn up by an authorized person, which is regulated by SNiP standards.

Important!Maintaining accompanying technical documentation is a mandatory procedure.

The act of carrying out hidden construction work is taken into account in the sixth section of the general work log. The act must strictly comply in the prescribed form, prepared in duplicate and signed by representatives of the construction commission. The act contains the following information:

1. A complete list of all work performed with quality control marks at each stage.
2. All information about project documentation, which confirms the entire operational process. The section may contain drawings, diagrams, explanatory notes.
3. Entering into the report the results of measurements and calculations that confirm the level of quality of the work performed.
4. List of findings indicating compliance with SNiP, ENiR and other requirements.

Today, finding a standard act confirming any operational process and guidelines for filling it out will not be difficult. Samples are available on specialized construction sites.

Safety at height

As they say in the song of the same name, installation workers send greetings to us from above! In fact, construction and welding and installation work at height is extremely dangerous work and requires compliance with a number of safety rules. It is strictly not recommended for beginners to undertake such work at height without appropriate training and experience.

Important! It is necessary not only to know the specifics of the work, to undergo training and study the manual for organizing safety at height.

For the personal comfort of workers at the site, equipping a construction site requires the arrangement of sanitary and hygienic premises, washrooms and dressing facilities, and specialized food outlets. Mandatory, prohibitory and warning signs must be placed on the territory of the construction site. What activities relate to construction and welding and installation work at height?

1. Carrying out ascent or descent at a height of more than five meters vertically, the angle of inclination is no more than 75 degrees.
2. All construction and welding work that involves the risk of falling from a height of 1.8 meters or more. Including all welding and installation work that is performed on machines or mechanisms, protruding objects or structures, and above the water surface.
3. Any activity on sites whose height is at least 1.8 meters, located closer than two meters to an unfenced drop, and the height of the fences is less than one meter.

The list of basic requirements for compliance with safety precautions at height includes the following points:

• permission to work is given to a person who has reached 18 years of age;
• before performing welding and installation work, the specialist must undergo a medical examination;
• certain requirements are imposed on the qualifications of a specialist and his professional preparedness to perform high-altitude work.
• The frequency of employee training should be at least once every three years (professional training and practical training are mandatory).

Important! Before starting high-altitude welding and installation work, a routine inspection of the site and its preparation is required.

To give permission to work, the possible causes of falls from a height, the reliability of fastenings, the presence of fragile, slippery or prone to destruction surfaces, and the strength of structures are first determined. The climatic conditions of high-altitude activities must be taken into account, a list of tools needed at height and ways to deliver them to the top must be drawn up. Basic rules for ensuring safety at height:

• All employees who have received clearance must be equipped with special safety belts. Each must have a test mark; permission to work with a belt that does not have the appropriate tag is prohibited.
• High-altitude welding and installation work should be carried out only during the daytime. If the regulations require night events, permission to work requires the installation of high-quality lighting on the site.
• Permission to work in winter implies periodic cleaning of the surface from ice and snow.
• The management does not give permission to work if the wind force is 6 points or more. During thunderstorms, snowfall or fog, performing construction and installation works at height is also prohibited.
• All decking, passages, fences, and scaffolding are installed by specialists taking into account load calculations. It is prohibited to move or rebuild them.
• When moving an employee up or down, he or she is prohibited from holding tools or equipment. It is lifted on separate cables.

Important! In addition to the direct danger of a worker falling from a height, there is a risk of injury to people below. To prevent this, warning signs and barriers are installed around the perimeter of the site.

The admission of unauthorized persons to the construction site is prohibited; management is responsible for this. Workers must not use pneumatic tools for work at heights or unauthorizedly extend ladders without preliminary calculation loads, carry out any activities on sites without fences or faulty structures. Compliance with safety regulations during production at height is the key to the personal health of the worker, as well as those located below at the site. Responsibility for maintaining safety rests with management. Carrying out construction and installation activities is the most important and responsible part of the entire construction process. Only competent planning, drawing up an estimate in accordance with E&R data, choosing professional specialists and optimal organization of construction and installation work together will help achieve the desired result.

Capital construction cannot be imagined without construction and installation work. Moreover, the object of construction and installation can be not only building metal structures, but also: foundations and supports, walls and roofs, window and door units, technological equipment, engineering systems.

Types of construction and installation work are always carried out taking into account the specific work area of ​​the construction site. The outcome of the project depends on the efficiency of construction and installation. Therefore, types of construction and installation work are proposed by the contractor and listed in terms of reference(TK) of the customer. In this publication we will consider the main types of construction and installation work necessary for the construction of buildings and structures from LMK.

Construction and installation work is the general name for all construction work.

• Construction works, usually called general construction and are associated with the construction of building structures, buildings and structures.
• Installation work is carried out using ready-made metal structures, their elements, connections and mounting parts.

Types of construction and installation work can be combined or performed separately. Since our company is a manufacturer, designer and builder, we offer our clients any type of construction and installation work in a comprehensive turnkey service.

All of the listed types of construction and installation work are included in the turnkey service, on which the customer can save up to 40% of the construction budget. For all questions of cooperation, please call 209-09-40! We'd love to hear from you!

The general definition of “construction and installation work” includes a set of works performed during the construction of industrial, commercial, infrastructure, civil buildings, installation of structures, engineering systems and equipment. The list of works falling under the wording “construction and installation” has been determined All-Russian classifier species economic activity 2018 (OKVED-2) with code classification OKVED 43.

In practice, construction and installation work looks like a set of actions to perform:

• construction work starting from the construction of the foundation and ending with the installation of the roof;
• installation work of finished structures, elements, parts and equipment.

In the process of constructing large-scale buildings and structures, it becomes necessary to carry out a large number of work that requires narrow specialization. To produce them, customers engage organizations that perform only these specific works, and in the end it turns out that several contractors work at the site. This approach makes it more difficult to control the quality of individual works and dilutes the responsibility of contractors for the entire construction as a whole. Therefore, it is more advisable to cooperate with a company that is capable of performing the entire cycle of construction and installation work, solving the assigned tasks independently and being responsible until the project is handed over to the customer.

Strategic priorities in competition

Today, large-scale construction of facilities for various purposes has been launched in all regions of Russia, and our company Innovative Designs has been successfully competing with other construction and installation organizations for more than 10 years. We have established stable, mutually beneficial cooperation with customers and partners due to the fact that work on sites is carried out comprehensively, from project development and “zero cycle” work to the implementation of the entire complex of construction and installation works and turnkey delivery of objects.

The professional growth and development of our company is facilitated by the presence of a team of highly qualified specialists, our own production base and a fleet of special equipment.

Benefits of collaborating with industry leaders

The company's production facilities allow us to manufacture metal structures of complex configurations, load-bearing floor trusses, organize and carry out complex construction processes. We have serious intellectual resources, as well as the technical capabilities to carry out construction and installation work in unlimited volumes and in a short time.

We take on objects of any complexity category, we have technical base to carry out a full cycle of construction and installation work, but we also do not refuse to work only in specific areas, which are carried out by our specialists with guaranteed quality and at an adequate cost.
