PPR and technological maps for the installation of metal structures of buildings and structures are developed without fail during the construction, repair or reconstruction of buildings (warehouses, production bases, hangars, factory workshops, offices, gas stations, car dealerships, ...) and structures (tanks, overpasses, sports facilities, ...). Carrying out work in the absence of these documents is prohibited. This may entail a stop of work from the authorities of Rostekhnadzor, the Customer, if work is being carried out on its territory, or other interested parties. It is also important that such a violation is subject to fines and other administrative measures.

At the stage of organizational preparation for the construction project, the Contractor, under an agreement with a specialized organization or on its own, is obliged to develop and agree with the Customer a PPR, PPRk and technological maps for the installation of metal structures. All decisions provided for therein are binding.

We develop PPR, PPRk and technological maps for the installation of metal structures of any objects. We take into account all customer requirements and bring all approvals to completion. We eliminate the identified comments during the verification stages and add additional missing data free of charge within the framework of the signed contract. The price of preparation is determined based on the provided initial data.

Project for the installation of metal structures

When performing work on the installation of building frames, warehouses (beams, trusses, rafters, braces, columns, braces, ...), metal structures of tanks (bottom, racks, wall, roof, fences, stairs, stiffening rings ...) and trestles for pipes and cables (racks, connections, beams, stairs, supports and consoles of pipelines and cable lines, ...), etc. it is necessary to develop a work plan for the installation of metal structures.

The complete work permit, with reference to local conditions, distribution of installation work into stages and taking into account the work being carried out in parallel, is issued to the responsible contractor. In turn, he familiarizes all working personnel with it against signature.

Schemes for installation of metal structures consist of a plan of the building and structure, locations of installation equipment. The boundary of the dangerous zone of collapse from mounted structures is indicated on the construction plan in the form of a red line with flags. The PPR includes technological maps for individual methods of work performed.

Technological maps for the installation of metal structures

Technological maps for the installation of metal structures must include methods for performing work with fastening methods. In the case of fastening structural elements to bolted connections, the technical documentation indicates the sequence of stages for preparation and lifting to the installation site. The tension forces of the bolts are indicated if there are requirements for bolting with controlled tension or without it if there is none. When fastening to welded joints, it is additionally necessary to develop welding flow charts.

Installation of vertically standing elements before their final design fastening, the technological maps describe the method of temporarily fastening them with braces to existing structures. Thereby excluding their possible collapse of loose elements of buildings and structures. After final fastening, the metal structures are aligned and straightened. Maximum deviations are contained in the “Quality Control” section of each technological map.

The technical specification is not drawn up for the entire facility as a whole, but specifically for operations. For example: a technical map for the enlarged assembly of metal structures at the installation site, a technical map for the installation of beams and vertical braces by welding, a technical map for fastening horizontal braces with bolts with controlled tension. Fastening structures at height can be done both from lifts and from scaffolding and scaffolding. Technological maps are also being developed for these works.

PPRk for installation of metal structures

In addition to the project for carrying out work on the installation of metal structures, the development of PPRk is also being carried out. It involves the selection and placement of lifting mechanisms at the construction site. The selection of truck cranes for installation is carried out according to the load-height characteristics of the crane, the parameters of the object under construction and the weight of the elements being lifted.

The PPRk contains diagrams for slinging mounted elements, horizontal and vertical connections of cranes, safety requirements, diagrams of the location of slingers and the person in charge at the time of slinging, slinging and lifting, diagrams of the joint operation of the crane and lifts for people (if they are used at the site).

- clean the grillages from dirt, sediment and concrete deposits;

- incoming quality control of metal structures entering installation;

- use a pencil or marker to mark the marks of the installation, longitudinal axes on the side faces of the structures.

2.3 Installation work

Installation of structures should be carried out using grips in accordance with sheets of graphic part 2-5. It is preferable to install elements “from wheels”. If necessary, use an area in the northern part of the construction site for storing elements (see Stroygenplan).

As the columns and half-timbers are installed, sections of load-bearing reinforced concrete walls (elevator unit) should be erected.

Before installing the load-bearing beams of the coating at elevation. +6,800 (top of the column, bottom of the beam) within grips 1 and 2, it is necessary to mount the beams of the mezzanine floor at elevation. +3.585 (top of the beam) and erect a section of monolithic flooring.

2.3.1 General sequence of work on installing a metal frame:

1. At the storage site, prepare columns, beams and connections for installation.

2. Install the columns in the design position. Install each column in the following technological sequence:

- Perform slinging of the column.

- Raise the column above ground level by 300 mm, make sure that the slings are securely fastened.

- Turn the column by lifting it while simultaneously turning the boom (or changing the reach) to the stop so that the vertical position of the crane's cargo ropes is maintained.

- Use a LIEBHERR 26K.1 crane (can be replaced with one of similar characteristics) to move the column to the installation site. The column should be delivered to the installation site at a height above 2300 mm away from obstacles encountered along the way.

- When installing a column on a foundation, clean the threads of the anchor bolts from rust and concrete residues with steel brushes, run them with a drill with the appropriate diameter and thread pitch, and check for axial marks.

- Install the column on temporary mounting pads, ensure temporary fastening and alignment of the column on the anchor bolts with paired nuts that fix the position of the base plate.

- Carry out design fastening of the column to the foundation. If necessary, brace the column in two mutually perpendicular directions using struts.

- After installation, unstrap the columns.

3. Install the beams in the design position. Install each beam in the following technological sequence:

- Installers should install a scaffold at the location where the beam is to be installed.

- Sling the beam.

- Use a LIEBHERR 26K.1 crane (can be replaced with one of similar characteristics) to move the beam to the installation site. Bring the beam to the installation site at a height of 500 mm from any obstacles encountered along the way.

- The installer should approach the place where the beam is connected to the column from the scaffold and perform their design fastening. Upon completion of work on securing the beam, the slinger unfastens the elements.

4. Mount the connections in the designed position. Install each connection in the following technological sequence:

- Installers should install a scaffold at the communication installation site.

- Perform slinging connection.

- Use the LIEBHERR 26K.1 crane (can be replaced with one of similar characteristics) to connect the connection to the installation site. The connection should be delivered to the installation site at a height above 500 mm away from obstacles encountered along the way.

- The installer from the scaffolding should approach the place where the connection is connected to the beam and column and carry out their design fastening. Upon completion of work on securing the beam, the slinger unfastens the elements.

5. Mount the purlins in the designed position in the following technological sequence:

- Installers should lay temporary flooring from boards 40 mm thick (in two mutually perpendicular layers) along the load-bearing beams.

- Perform slinging of the purlin.

- Using a Liebherr 26 K.1 crane (can be replaced with one of similar characteristics), move the run to the installation site at a height above 500 mm from obstacles encountered along the way.

- The installer should approach the place where the purlin is attached to the beams from the scaffold and carry out the design fastening. Upon completion of work on securing the girder, the slinger unslings the elements.

6. Carry out a visual inspection and draw up a report on the work performed.

Loads must be slinged in accordance with slinging diagrams. For work, slings should be used that correspond to the weight and nature of the load being lifted, taking into account the number of branches and the angle of their inclination; the slings should be selected so that the angle between their branches does not exceed 90°.

Loads must not be moved while there are people underneath them. The slinger can be near the load while it is being lifted or lowered if the load is at a height of no more than 1000 mm from the platform level.

2.3.2 Crane operation

The work is carried out using a quickly erected tower crane LIEBHERR 26K.1 (can be replaced with a similar one in terms of characteristics).

Preparation of the workplace

Before starting work with a crane, you must complete:

- install stands with sling diagrams and a table of load weights in the crane operating area and at the storage area;

- install safety signs, sign No. 3 along the boundary of the dangerous zone, sign No. 2 along the line limiting the crane service area.

2.2 Transportation and storage

The strapping elements should be delivered to the construction site using the MMC FUSO manipulator.

Preparation of metal structures for transportation must comply with GOST 26653. Metal structures with cross-sectional dimensions up to 50 mm inclusive are tied into bundles, skeins or bundles of skeins, and over 50 mm - bundled into bundles at the request of the consumer. Bent profiles are tied into bundles.

The cross-section of packs of metal structures, depending on the size and shape of the cross-section, should approach a circle, rectangle or hexagon. By agreement between the manufacturer and the consumer, a different cross-section of the packs is allowed.

When packing metal structures of measured length, the ends of the bundle must be aligned on one side, the protruding ends on the other side must not exceed the maximum length deviations established in the regulatory documentation (ND) for specific types of rental products. By agreement between the manufacturer and the consumer, packaging without aligning the ends is allowed.

During loading and unloading operations, transportation and storage, metal structures must be protected from mechanical damage, for which they should be laid in a stable position on wooden supports and secured (during transportation) with the help of inventory fasteners, such as clamps, clamps, turnstiles, cassettes, etc. .P. Deformed structures must be rejected and replaced with new ones. Do not drop structures from vehicles or drag them on any surface. During loading, slings made of soft material should be used.

The weight of a pack of metal structures, as well as unpackaged rolled products, should not exceed:

- for manual loading and unloading - 80 kg (up to 25 kg per worker);

- with mechanized loading and unloading - up to 1.6 tons.

The passage of vehicles with metal structures, as well as unloading, must be under the strict control of the person responsible for the safe movement of cargo.

Mineral wool boards and sheet metal are also delivered to the construction site using the MMC FUSO manipulator. The elements and materials received at the construction site are placed in the operating area of ​​the installation crane. All materials must be stored in a position appropriate for transport, sorted by size. It is necessary to store materials under a canopy in conditions that prevent their damage.

2.3 Workplace organization

Workplaces must be illuminated in accordance with the requirements of GOST 12.1.046-85, table 1:

Table 1

Lighting standards for workplaces

Construction sites and work areas	Lowest illumination, lux	The plane in which illumination is normalized	Level of the surface on which illumination is normalized
1. Loading, installation, lifting, unloading of equipment, building structures, parts and materials by cranes		Horizontal	At the sites for receiving and supplying equipment, parts designs and materials
		Vertical	On the crane hooks in all positions from the operator's side
2. Non-mechanized unloading and loading of structures, parts, materials and tilting		Horizontal	At cargo reception and delivery sites
3. Installation of structures		Horizontal	Throughout the entire height of the assembly
		Vertical
4. Integrated assembly of strapping elements (docking, welding)		Horizontal	At ground or work surface level
		Vertical	Throughout the entire height of work
5. Approaches to workplaces		Horizontal	On formworks, platforms and approaches
6. Storage room for small technological equipment and installation materials		Horizontal	At floor level

Concentrations of harmful substances in the air of the working area, as well as noise and vibration levels at workplaces should not exceed established sanitary and hygienic standards.

Microclimate parameters must comply with sanitary rules and standards for hygienic requirements for the microclimate of industrial premises.

Machines and units that create noise during operation should be operated in such a way that sound levels in workplaces, areas and on the construction site do not exceed the permissible values ​​​​specified in sanitary standards.

When operating machines, as well as when organizing workplaces, to eliminate the harmful effects on workers of increased noise levels, the following should be used:

- technical means (reducing machine noise at the source of its formation; the use of technological processes in which sound levels at workplaces do not exceed permissible levels, etc.);

- remote control;

- individual protection means;

- organizational measures (choice of a rational mode of work and rest, reducing the time of exposure to noise factors in the work area, treatment, preventive and other measures).

Areas with sound levels above 80 dBA are indicated with danger signs. Working in these areas without wearing personal hearing protection is not permitted. Workers are not allowed to stay in areas with sound levels above 135 dBA.

Production equipment that generates vibration must meet the requirements of sanitary standards.

2.4 Geodetic works

During the work, geodetic control is carried out. Control consists of checking compliance with basic design requirements. Geodetic control should be carried out directly during the execution of work, after completion of work at the site or site, when accepting work from the performers.

Alignment work begins with reference to the reference geodetic base; during the construction process, the work must ensure that it is carried out in situ from the points of the geodetic alignment base with a given accuracy of axes and marks.

A geodetic alignment basis for construction should be created taking into account:

- design and existing placement of buildings (structures) and utility networks at the construction site;

- ensuring the safety and stability of signs fixing the points of the alignment base;

- geological, temperature, dynamic processes and other influences in the construction area that may have an adverse effect on the quality of construction of the alignment base;

- use of the created geodetic alignment base during the operation of the constructed facility, its expansion and reconstruction.

The accuracy of constructing the construction site alignment network should be taken in accordance with the data given in SNiP 3.01.03-84*.

During the operational period the following is checked:

- safety and immutability of the position of the plan-height base;

- compliance with the setting out of structural elements and alignment axes;

- accuracy of transfer of the main axes of structures;

- correctness of the plan-height position of all structural elements.

During the acceptance control process upon completion of construction, the following is controlled:

- compliance of all geometric parameters of the earthen structure with the requirements of the project and regulatory documents;

- timely and reliable completion of as-built surveys during the construction of column block linings and upon its completion.

The result of this work is as-built geodetic documentation.

Geodetic foundation signs must be supervised during the construction process. Their safety and stability are constantly checked.

All geodetic work during the construction period must be recorded in a work log, which is maintained in parallel with the general work log by the supervisor directly carrying out the construction of this facility.

All executive geodetic documentation is signed by the performing surveyor, chief engineer or person responsible for the work. Acceptance and delivery documentation includes:

- As-built surveys of the mounted piping elements of the column block.

All diagrams indicate the design and actual dimensions or deviations from the design dimensions in height and in plan. The coordinate and elevation system is local. The relative level of 0.000 is taken to be 276.150.

Signed as-built surveys are transferred to the Customer along with acts for hidden work to confirm the scope of work completed.

General management of geodetic control is assigned to the chief engineer.

The results of control observations are recorded in journals.

AKB Monolit has been developing PPR for more than 10 years.
The PPR for the installation of metal structures is developed by our specialists based on the initial data provided by the PPR customer.
The PPR for the installation of metal structures for construction organizations is the main organizational and technological document developed for the purpose of safe construction of the building. The presence of a PPR indicates the readiness of the construction organization to begin construction and installation work.

Initial data for ordering PPR for installation of metal structures
1) Assignment for the development of PPR;
2) Construction Organization Project (COP);
3) Working documentation (DM);

Composition and content of PPR for installation of metal structures
1) Work schedule;
2) Construction master plan (stroygenplan);
3) Schedule of arrival of metal structures at the site;
4) Schedule of movement of workers around the facility;
5) Schedule of movement of the main construction vehicles around the site;
6) Technological diagrams (maps) for the installation of metal structures;
7) Explanatory note containing:
- solutions and instructions for the installation of metal structures;
- requirements for quality and acceptance of work;
- safety and labor protection requirements;
- fire safety requirements;
- environmental protection measures.

The PPR developed by our specialists provides for measures to ensure the stability of metal structures, taking into account their design and layout solutions (including installation connections), the material of structural elements and local conditions.

The stability and geometric immutability of mounted structures of buildings and structures is ensured by compliance with the technological sequence of installation of structural elements and blocks. This is achieved by our specialists dividing the building (structure) in plan and height into separate stable sections (spans, floors, tiers), the installation sequence of which ensures the stability and immutability of the mounted structures in this section.

Even before the start of the installation of metal structures at the construction site, according to the construction organization project (CDP), the work of the preparatory period, the excavation work and the “zero cycle” work must be completed.

Parts of steel structures are usually manufactured at the plant in accordance with the requirements of standards or technical specifications for products of specific types, types and brands according to working documentation (KM, KMD), approved by the developer and accepted for production by the manufacturer.

Work on enlarging steel structures and preparing them for installation is carried out using a load-lifting crane (truck, crawler or tower). The choice of a load-lifting crane can be carried out during the development of a work execution project (WPP), but with mandatory coordination with the organization that developed the construction organization project (COP).

As a rule, the installation of load-bearing metal structures of one-story buildings is carried out in the following technological sequence:

1) Installation of metal columns of the building. The installation of columns begins with a tie panel. If for some reason the specified requirement cannot be met, then it is necessary to install a temporary bonded panel from the first installed columns of the row, beam or spacer and temporary vertical connections between them, installed below the level of the beam (spacer). Then the next column is installed and secured to the temporary bracing panel with a beam or spacer.

2) Installation of coating structures. Installation of metal roofing structures begins with a bonded panel, and if this is not possible, then with any panel, establishing horizontal and vertical connections between adjacent trusses. The next truss to be installed must be secured to the bracing panel with a spacer.

When installing load-bearing metal structures of multi-story buildings, after installing the columns, crossbars are mounted along the axis, ensuring the stability of the resulting frame in the transverse direction. In the longitudinal direction, stability is ensured using vertical connections along the columns and spacer elements. If the stability of the building in the longitudinal direction is ensured by wall structures (which should be indicated in the working documentation), then they should be installed simultaneously with the frame and floors.

In all cases, during the construction of buildings, a mandatory condition is the complete readiness of the assembled steel structures in the section for subsequent work, regardless of the state of installation of the structures in adjacent sections.

The installation of steel structures is usually carried out by teams of workers, each of which includes: assemblers, electric welders, crane operators, and general workers.

Mounted columns, beams and purlins (trusses) must be prepared in advance and placed in the operating area of ​​the crane.

The area where metal structures are being installed must have a temporary fence to prevent unauthorized persons from entering the work area. A temporary road must be laid along the perimeter of the building or structure being constructed to move the installation crane and transport steel structures to the installation site. There should also be storage areas for load-handling devices, a stand with sling diagrams and a table of load weights, spotlights for illuminating workplaces at night, and a wheel washing station.

At PPR, our specialists develop diagrams of horizontal and vertical connections for a load-lifting crane when installing metal structures of a building or structure.

Installation work must begin after delivery and acceptance of the foundations of a building or structure - column supports, if there is an act for hidden work. During the acceptance process, an instrumental quality check of previously completed work must be performed. When checking, the position of the transverse and longitudinal axes of the foundation-supports in plan and the elevation marks of the supporting surfaces of the foundations must be determined.

Installation of metal structures is carried out “bottom-up”, in sections (clamps), using the “crane” method. The installation sequence is developed in the PPR and it must ensure stability and geometric immutability of structures.

Welding or bolting connections are made only after checking the correct installation of structures.

PPR for installation of sandwich panels

Installation of enclosing structures made of lightweight profiled sheets or wall and roof “sandwich panels” is usually carried out in a separate process after the installation of load-bearing metal structures.

Installation of steel profiled sheets of walls and roofs is carried out according to markings that ensure fixation of the calculated width of the profiled sheet (the distance between the axes of the outer corrugations).

Fastening of profiled sheets of roofing and walls to the load-bearing elements of the metal frame of a building or structure is carried out using self-tapping or self-drilling screws or by shooting with dowels in accordance with the requirements of the working documentation (DD).

Installation of wall and roof sandwich panels is carried out panel by panel. Slinging of panel packages is carried out only using strappings with vertically located slings. Slinging of “sandwich panels” during installation is carried out only using flexible fabric slings or other methods, including using special traverses, which prevent jamming of the metal edges of the panels and damage to the paint layer.

Sealing gaskets in the vertical and horizontal joints of the sandwich panels are laid before the panels are installed.

The enlarged assembly of walls from light panels into cards is carried out on stands in the operating area of ​​a load-lifting crane. Maximum deviations of maps are carried out according to the working design.

All linings of horizontal and vertical joints, as well as corner elements of panels, are placed on sealant to prevent moisture from entering the joint.

If there are no special requirements in the working documentation for deviations of the mounted wall and roof panels, they should not exceed standard values.

Types of installation connections when developing PPR

When installing metal structures, various types of installation connections are used:

1) Installation connections without controlled bolt tension. This type of installation connections includes shear bolted connections, in which external forces are perceived due to the shear resistance of the bolts and the shear resistance of the connected elements. When assembling such mounting connections, the holes in the structural parts must be aligned and secured against displacement of the parts with assembly plugs, and the assembled packages must be tightly bolted.

2) Mounting connections with high-strength, tension-controlled bolts. Installation connections with high-strength, tension-controlled bolts include:

Friction and shear-resistant connections, in which external forces are perceived due to the resistance of frictional forces arising along the contact planes of the connected elements from the pre-tensioning of the bolts;

Friction-shear assembly connections, in which external forces are perceived mainly by overcoming the compression resistance of the flanges from the pre-tensioning of high-strength bolts.

3) Special installation connections:

Shooting with high-strength dowels;

Installation of self-tapping and self-drilling screws;

Contact spot welding;

Electric rivets;

Folding of longitudinal edges.

A characteristic feature of special installation connections is that to perform them, a one-sided approach to the structural elements being connected is sufficient. The main area of ​​special installation connections used is the fastening of the enclosing structures of buildings or structures.

4) Welded joints. The type of welding equipment is selected depending on the welding method, conditions and features of welding work and the specified parameters of the welding process. Basic welding methods used in the installation of metal structures.

Manual arc welding with coated electrodes. It is a universal and basic welding method for making seams in all spatial positions when enlarging and installing metal structures.

Mechanized welding with self-shielding flux-cored wire. It is used primarily for making connections in the lower position when enlarging structures at the bottom and for welding extended seams at the design level.

Mechanized welding in shielding gases with solid wire. It is used for enlarged welding of structures in the lower position with protection of the welding zone from the wind.

Automated submerged arc welding. It is used for welding straight, extended seams in the lower position when enlarging sheet blanks and structures.
