A General instructions

1 All factory connections of metal structure elements are welded. Field welded joints are indicated in knots.

2 Welding materials corresponding to steels shall be taken according to Table 55* of SNiP II-23-81* (1991 edition).

3 Instructions for welding structures:

Butt, girdle and fillet welds in elements longer than 2 m are recommended to be performed by automatic submerged arc welding; other factory seams of all elements - by mechanized welding in a carbon dioxide environment or in its mixture with argon;

The values of the coefficients β f , β z and the design resistance of the weld metal to the shear R ωf , R ωz - taken according to tables 3, 4*, 34* SNiP II-23-81*;

The dimensions of the fillet welds indicated in the drawings are taken from the calculation: factory - for mechanized welding in a carbon dioxide environment with a welding wire with a diameter of 1.4 - 1.6 mm in the lower position and horizontal on a vertical plane; wire with a diameter of 0.8 - 1.4 mm - in vertical and ceiling positions; mounting - for manual arc welding;

When switching to other types of welding or welding materials, as well as when applying special measures aimed at improving the productivity of the welding process, the dimensions of all specified welds must be recalculated in accordance with the instructions of SNiP II-23-81 *;

When welding structures made of steel with a design resistance of up to 2400 kg / cm 2, welded with steels of higher strength, use electrodes of the E42A type.

4 The dimensions of design welds should be taken depending on the forces indicated on the diagrams and in the lists of structural elements, except for those specified in the units, and also depending on the thickness of the welded elements.

5 Welds with grooves should be performed with full penetration, with obligatory cleaning and subsequent welding of the root of the weld. The use of welding on the remaining linings is prohibited, except for certain special cases specified in the KM drawings or subject to agreement with the author of the project.

The quality of all full penetration welds shall be verified by non-destructive testing methods. Quality control of welded joints should be carried out taking into account the requirements of GOST 23118-99 “Building steel structures. General technical conditions".

The beginning and end of butt welds and fillet welds with full penetration should be led out of the welded parts to the lead plates, followed by their removal and cleaning of the installation sites.

6 Minimum legs of fillet welds should be taken according to Table 38* of SNiP II-23-81*.

The minimum length of fillet welds is 60 mm.

7 When welding tee, fillet and cruciform joints made of low-alloy steel C345 with a thickness of 20 mm or more, in order to reduce the likelihood of destruction of welded joints associated with physical inhomogeneity of rolled products in thickness, the development of welding technology should provide for additional technological measures:

Mandatory thorough calcination of welding consumables and their release into operation in accordance with the requirements for their preparation, storage and use;

Mandatory cleaning of the welded elements before welding from mill scale, rust and other contaminants to a width of 20 mm in each direction from the cutting edge;

Compliance with the design dimensions of calculated and off-design fillet welds, preventing their reduction;

Exclusion of sharp sinkings between beads with a depth of more than 0.5 mm, undercuts at the transition from the weld metal to the base metal, and other stress concentrators;

Inspection of welds with full penetration by ultrasonic flaw detection or inspection by penetrating radiation to detect possible cracks and discontinuities in welds and heat-affected zone.

8 Clause 7 lists the basic requirements for making welded joints of metal structures, taking into account the physical inhomogeneity of rolled products in thickness. Manufacturers, assembly organizations (if it is necessary to perform field welding), based on the accepted technology and available practical experience, can also apply other technological measures aimed at ensuring the quality of welded joints in accordance with the KM drawings and the requirements of the standards.

9 In order to prevent the formation of cracks in welded joints and lamellar cracking of rolled products under the influence of welding stresses and loads, pay special attention to strict adherence to the technology of assembly and welding of metal structures, ensuring the requirements of norms, technical conditions, standards, the work of the quality control department of the plant at all stages of the manufacture of metal structures .

10 The final quality control of welded joints of structures made of steels C345 should be carried out no earlier than 48 hours from the moment of completion of welding of the tested assembly. Identified defects in welded structures should be examined and corrected. Without fulfilling these requirements, it is prohibited to prime and send metal structures from the manufacturing plant and to accept them for installation.

11 Welding of joints made of high-strength steels C375 and higher must be carried out according to a specially developed technology that takes into account the specifics of structures, their stress state and other factors.

Welding technology can be developed by the Institute of TsNIIPSK them. Melnikov under a separate agreement (agreement).

B Instructions for making welded joints of rolled and welded beams

1 Factory and assembly connections (joints) of rolled and welded beams are made end-to-end with full penetration of the edges of the shelves and walls and must be equal in strength to the base metal of the section.

2 The location of the mounting joints is indicated either in the KM drawings, or is determined by the manufacturer (together with the installation organization) with mandatory agreement with the authors of the project.

3 The technology of assembly and welding of factory and field joints (joints) can be developed by the Institute of TsNIIPSK them. Melnikov in the framework of an additional agreement (agreement).

B Guidelines for the implementation of welded joints of elements from angle profiles with fillings in the nodes of lattice structures

When making welded joints of lattice elements from angle profiles with packing of roof and sub-rafter trusses, branches of columns, ties and other lattice structures, the following additional requirements must be observed (see node A):

1 Welds that attach the elements of the lattice to the gussets should be made with welding of the ends of the corners.

2 The length of the overlap of the corners on the gusset l n1, l n2 is determined based on bearing capacity gussets (tear, shear, etc. factors) and welds along the butt and feather, ensuring the transfer of the forces acting in them. Lengths l n1, l n2 take at least 1.7b 0 along the butt and 1.1b 0 along the feather (where b 0 is the width of the corner shelf adjacent to the gusset).

3 When assembling the nodes, it is necessary to press the corners of the lattice to the gusset along the entire plane of junction in order to ensure the requirements for clearances in accordance with GOST 14771-76* or GOST 5264-80* (connection type T1, H1).

Setting tacks is allowed at a distance of 30 - 35 mm from the end of the corner.

4 Welds for attaching corners to gussets should be performed in the following sequence:

4.1 Weld the seam Ш1 along the feather of the corner with the beginning at the edge of the gusset (see paragraph 5) and ending at the middle of the end of the corner;

4.2 Weld the seam Ш2 along the butt of the corner with the beginning at the edge of the gusset (see paragraph 5) and ending in the middle of the end of the corner with the overlap of the seam Ш1 by 20 - 30 mm;

4.3 Perform, if necessary, additional passes of the seams Ш1 and Ш2 along the butt and feather with an offset of the beginning of each subsequent pass by 10 mm, providing the calculated values of the legs.

5 The beginning of the seams Ш1 and Ш2 should be performed with a deviation from the edge of the gusset by at least 10 - 15 mm.

6 Weld craters must be welded and must not be cracked.

7 The quality of welds must be controlled.

Directions
for making mounting connections on bolts

A Friction joints on high-strength bolts

1 The joints are designed in accordance with the provisions of SNiP II-23-81* (edition 1991) and calculated assuming the transmission of the forces acting in the elements by the friction forces arising along the contacting planes of the connected elements from the tension of high-strength bolts. The distribution of the longitudinal force between the bolts is assumed to be uniform. For the definition of forces on bolts from acting loads, see the instructions on the KM drawings. The numerical value of the friction forces is directly proportional to the values of the friction coefficients on the contact surfaces, the pretensioning forces of high-strength bolts, and the number of friction planes.

Bolts М20, 24-6gх1.110 GOST 22353-77*;

Nuts M20, 24-6N.110 GOST 22354-77*;

Washers 20, 24 GOST 22355-77*.

Note. At the design temperature of the construction area from -40 °С to -65 °С, bolts and nuts of the climatic modification KhL, placement category 1 (ХЛ1) should be used.

3 The hole diameter is taken equal to 28 mm for M24 bolts and 23 mm for M20 bolts, except as specified in the drawings. When drilling holes, use conductors or other specialized equipment that ensures that the requirements for quality and tolerances in the size of the hole are met in accordance with the requirements for the manufacture of the structure (see section IV).

4 In places where high-strength bolts are installed, the contact surfaces of structural elements and linings should not be primed or painted.

5 Method of processing (cleaning) the contact surfaces of the connection - with steel brushes without preservation. The calculated sign of the friction coefficient is taken to be μ = 0.35.

6 Way of adjusting the tension of the bolts - according to the moment of twisting ("according to M").

7 The tightness of the package screed is checked with a probe 0.3 mm thick, which should not penetrate into the zone of the extreme hole, limited by a radius of 1.3d 0 from the center of this hole (d 0 is the diameter of the hole).

8 After acceptance of the connection, at each node, in a place accessible for inspection, the stigma of the foreman and the person responsible for making the bolted connection is applied. The height of the stamp must be at least 8 mm. The location of the brand (about 100 × 100 mm in size) is painted with white paint.

9 All work on tensioning and tension control should be recorded in the control log for the implementation of field connections on high-strength bolts.

10 The number of bolts in the joints and the thickness of the linings are determined in accordance with the Guidelines for the calculation of knots on high-strength bolts, if they are not specified on the drawings of the knots.

11 Overlays of the same geometric shape, but differing in thickness by less than 4 mm, should be unified and taken according to the largest of them. It is not allowed to use overlays of the same thickness and geometric shape from different steels.

12 The distances between the centers of the hole and to the edge of the element in the longitudinal and transverse directions are taken in accordance with the table. 39 SNiP II-23-81 *, except for those specified on the KM drawings.

13 If the difference in the planes of the connected elements is from 0.5 to 3 mm, to ensure a smooth bending of the lining, the edge of the protruding part must be smoothed with an emery stone at a distance of at least 30 mm from the edge. With a difference of more than 3 mm, gaskets made of steel C235 and higher in accordance with GOST 27772-88 should be used and processed on installation from both sides in the same way as the lining.

14 Each bolt is installed in connection with two round washers: one is placed under the head of the bolt, the other under the nut. It is forbidden to put more than one washer on each side of the package.

B Connections on permanent bolts of accuracy class C, working in shear and tension

1 Connections on bolts of accuracy class B are calculated assuming the transfer of forces acting in the elements by the resistance of the connected elements to crushing, bolts to shear and tension. When performing field connections on bolts, be guided by the "Recommendations and standards for the technology of setting bolts in the field joints of metal structures", Moscow, TsNIIprojectstalkonstruktsiya, 1988.

1.2 Protection of steel building structures against corrosion should be carried out in accordance with the requirements of SNiP 2.03.11-85 "Protection of building structures against corrosion", GOST 9.402-80 "Preparation of metal surfaces before painting", SNiP 3.04.03-85 "Protection of building structures and structures from corrosion.

1.3 To ensure the reliability of protective coatings, metal structures must be fully protected from corrosion at the factory. If the Customer does not have the opportunity to place an order at a plant that has equipment for complete protection against corrosion of metal structures, surface preparation and priming can be carried out at the plant, and final painting at the construction and installation site.

1.4 The technological process of protecting metal structures from corrosion includes the following operations:

Surface preparation before painting;

Application and drying of paint and varnish coatings;

Quality control of work performed.

2 Surface preparation before painting

2.1 Surface preparation includes cleaning the surface of metal structures from oxides (rolling scale and rust), mechanical, grease and other contaminants.

Auxiliary elements, burrs, welding spatter, flux residues must first be completely removed from the surface of metal structures, welds cleaned, sharp edges with a radius of less than 0.3 mm rounded using a manual or mechanized abrasive tool.

2.2 Degreasing of the surface should be carried out to degree 1 in accordance with GOST 9.402-80 with brushes or rags moistened with white spirit, nefras or B-70 grade gasoline.

2.3 Cleaning of the surface of newly manufactured structures from oxides should be carried out by shot-blasting or shot-blasting (sandblasting) methods to degree 3 in accordance with GOST 9.402-80, provided that the interval from the moment of manufacture of painted metal structures to the supply of heat in the building does not exceed 6 months and to degree 2 - with interval of more than 6 months. At the same time, painted metal structures should be stored on wooden linings with polyethylene film linings.

The surface, cleaned to degree 2, should be matte, gray in color, with a uniform roughness, the maximum value of which is 40 microns, without residues of corrosion products and mill scale visible to the naked eye.

On the surface of metal structures, cleaned from oxides up to degree 3, the presence of individual stripes and inclusions of rust and mill scale is allowed, occupying no more than 5% of the surface.

2.4 To prevent the formation of secondary rust on the cleaned surface, the interval between surface preparation and application of protective coatings should be kept to a minimum. It should not exceed 6 hours outdoors and 24 hours indoors under conditions that exclude dust, oil, moisture, other contaminants from entering the cleaned surface and condensation of moisture on it.

3 Paint application

3.1 The color of the coating is chosen by the Customer in accordance with the recommendations of the architect.

3.2 Applying paint and varnish coatings should be carried out according to one of the options: option 1 - at an interval from the moment of manufacture of painted metal structures to the supply of heat to the building no more than 6 months, option 2 - at an interval from 6 months to 2 years.

Option 1

1 Primer GF-0119 (or FL-OZK, GF-021) - 1 layer;

2 Enamel PF-115 (or PF-133) - 2 layers.

The total thickness of the coating is at least 60 microns.

Option 2

1 Primer VL-02 - 1 layer;

2 Primer AK-070 (or AK-069) - 1 layer;

3 Enamel ХВ-124 (or ХВ-125, ХВ-16) - 4 layers.

The total thickness of the coating is at least 110 microns.

3.3 Application of paint and varnish coatings should be carried out at an ambient temperature of at least 15 °C and relative air humidity of not more than 80%, unless otherwise indicated in the regulatory and technical documentation for each specific material.

3.4 The application of paint and varnish coatings should be carried out by methods of pneumatic or airless spraying. When painting fasteners and correcting defects in the coating of metal structures after its installation, it is allowed to use a brush.

To ensure high-quality painting of the most corrosion-vulnerable places, sharp edges, corners, welds and hard-to-reach places should be painted with a brush before spraying.

3.5 Paint and varnish materials should be prepared for work in accordance with GOST or TU for these materials.

3.6 Paint coatings damaged as a result of transportation, storage and installation of metal structures must be restored.

4 Quality control

4.1 The paintwork materials used must comply with the requirements of GOST or TU for these materials, have manufacturer's passports and have not expired.

4.2 The quality of the applied coating is controlled in appearance by visual inspection of 100% of the surface of the structures, drying time, adhesion and thickness.

The applied paint coating must be continuous (without non-painted areas), without foreign inclusions, streaks, wrinkles, bubbles, pockmarks and other defects that reduce the protective properties of coatings. The coating must be uniform and sufficient in thickness, have satisfactory adhesion (1 - 2 points). In terms of its decorative properties, the coating must comply with the requirements of class V - VI according to GOST 9.032-74.

The adhesion of coatings is determined by the method of lattice cuts according to GOST 15140-78.

The thickness of paint coatings is determined by non-destructive testing using thickness gauges of magnetic or electromagnetic types, for example, MT-33N, MT-50NTs or other brands.

It is preferable to apply paint coatings of different colors (each layer of its own color), which allows you to control the order and number of applied coating layers and get a higher quality paint coating.

4.3 Coatings made in accordance with these requirements provide protection of metal structures from corrosion for 5 years for the coating system according to option 1 and 10 years for option 2.

5 Protection of bolted field connections

5.1 Protection of connections on high-strength bolts should be carried out in accordance with clause 4.34 of SNiP 3.03.01-87, and also taking into account the following requirements: the contours of the lining, bolt heads, nuts and protruding parts of the bolt threads should be protected using enamel with aluminum powder in accordance with the instructions in paragraph 5.2.

5.2 To protect joints on high-strength bolts at the assembly site, enamels specified in Section 3 should be used with the initial viscosity (without dilution with a solvent) with the addition of aluminum powder to a consistency that prevents the enamel from leaking into the package by more than 20 mm.

5.3 Gaps in the joints between elements connected with high-strength bolts (see Fig. 1) should be filled with NGM non-hardening sealing mastic according to GOST 14791-79.

5.4 After assembling the connection on bolts without controlled tension, field connections, including bolt heads, nuts, protruding parts of the bolt threads, must be cleaned, primed, and the gaps in the places of drops filled up.

The primer used to protect the respective structure may be used to protect the bolted joint. For putty, use the composition according to the recipe in paragraph 5.2.
