Directions
on welding and selection of welding consumables

A General instructions

1 All factory connections of metal structures are welded. Mounting welded joints are indicated in the nodes.

2 Welding materials corresponding to steels are taken according to table 55 * SNiP II-23-81 * (1991 edition).

3 Instructions for welding structures:

Butt, waist 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 an atmosphere of carbon dioxide or in its mixture with argon;

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

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

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

When welding steel structures 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 the 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 nodes, and also depending on the thicknesses of the welded elements.

5 Weld seams with grooving should be performed with full penetration, with obligatory stripping and subsequent welding of the root of the seam. 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.

All full penetration welds shall be non-destructively inspected for quality. Quality control of welded joints should be carried out taking into account the requirements of GOST 23118-99 “Steel building structures. General technical conditions ".

The beginning and end of butt welds and fillet welds with full penetration should be brought out of the welded parts onto the lead-out strips, followed by their removal and cleaning of the installation sites.

6 The minimum legs of fillet welds should be taken according to table 38 * SNiP II-23-81 *.

The minimum length for fillet welds is 60 mm.

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

Compulsory thorough calcination of welding materials and their issuance for work in accordance with the requirements for their preparation, storage and use;

Obligatory 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 groove edge;

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

Elimination of sharp sinks between rollers with a depth of more than 0.5 mm, undercuts during the transition from the weld metal to the base metal and other stress concentrators;

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

8 Clause 7 lists the basic requirements for welded joints of metal structures, taking into account the physical inhomogeneity of rolled products in thickness. Plants - manufacturers, installation organizations (if necessary to perform assembly welding), on the basis of the adopted technology and available practical experience, can apply other technological measures aimed at ensuring high-quality performance 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 layered cracking of rolled products under the action of welding stresses and loads, Special attention for strict observance of the technology of assembly and welding of metal structures, ensuring the requirements of norms, technical conditions, standards, the work of the plant's quality control department at all stages of the manufacture of metal structures.

10 The final quality control of welded joints of structures made of S345 steels should be carried out no earlier than 48 hours after the completion of welding of the tested unit. Identified defects in welded structures must be examined and corrected. Without meeting these requirements, it is prohibited to prime and send metal structures from the manufacturer and their acceptance at installation.

11 Welding of joints from high-strength steels C375 and higher should be carried out using 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 TsNIIPSK Institute named after V.I. Melnikov under a separate agreement (contract).

B Instructions for making welded joints of rolled and welded beams

1 Factory and erection joints (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 the obligatory agreement with the authors of the project.

3 The technology of assembly and welding of factory and erection joints (joints) can be developed by the Institute of TsNIIPSK im. Melnikov as part of an additional agreement (contract).

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

When making welded joints of lattice elements made of corner profiles with packings of rafter and rafter trusses, column branches, ties and other lattice structures, the following additional requirements must be observed (see node A):

1 Welding seams attaching the lattice elements to the gussets should be performed with welding the ends of the corners.

2 The lengths of the overlap of the corners on the gusset l n1, l n2 shall be determined based on the bearing capacity of the gusset (pull-out, cut, etc. factors) and welded seams along the butt and feather, ensuring the transfer of forces acting in them. The lengths l n1, l n2 should be at least 1.7b 0 along the butt and 1.1b 0 along the pen (where b 0 is the width of the corner shelf adjacent to the gusset).

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

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

4 Weld seams of fastening corners to gussets should be performed in the following sequence:

4.1 Carry out welding of the Ш1 seam along the corner 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 Welding the Ш2 seam along the edge of the corner with the beginning at the edge of the gusset (see item 5) and ending in the middle of the edge of the corner with the overlap of the Ш1 seam by 20 - 30 mm;

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

5 Beginning of seams Ш1 and Ш2 with a deviation from the edge of the gusset by at least 10 - 15 mm.

6 The craters of the welds must be welded and free from cracks.

7 The quality of welds should be checked.

Directions
for making field connections with bolts

A Friction joints with high strength bolts

1 The joints are designed in accordance with the provisions of SNiP II-23-81 * (edition 1991) and are calculated assuming the transfer of forces acting in the elements by 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 determination of the bolt forces from the 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 pre-tensioning forces of high-strength bolts and the number of friction planes.

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

Nuts М20, 24-6Н.110 GOST 22354-77 *;

Washers 20, 24 GOST 22355-77 *.

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

3 The hole diameter is assumed to be 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 quality requirements and tolerances in hole dimensions 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 joint - steel brushes without preservation. The calculated value of the coefficient of friction is taken μ = 0.35.

6 Method of adjusting the tension of the bolts - by the tightening torque ("according to M").

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

8 After the connection has been accepted, the brand of the foreman and the person responsible for making the bolted connection is applied to each node in an accessible place for inspection. The height of the stamp must be at least 8 mm. The place where the stamp is installed (about 100 × 100 mm in size) is painted with white paint.

9 All tensioning and tension control work should be recorded in the high-strength bolt assembly control log.

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

11 Plates of the same geometrical shape, but differing in thickness by less than 4 mm, should be unified and adopted for the larger of them. It is not allowed to use overlays of the same thickness and geometrical shape made of different steels.

12 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 table. 39 SNiP II-23-81 *, except for those specified in the KM drawings.

13 With a difference in the planes of the elements to be connected 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 S235 and higher should be used in accordance with GOST 27772-88 and processed on installation from both sides in the same way as the pads.

14 Each bolt is fitted with two round washers, one under the bolt head and 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 B, working for shear and tension

1 Connections on bolts of accuracy class B are calculated on the assumption that the forces acting in the elements are transmitted by the resistance of the connected elements to shear, shear and tension. When performing mounting connections on bolts, be guided by "Recommendations and standards for the technology of bolting in mounting joints of metal structures", Moscow, TsNIIproektstalkonstruktsiya, 1988

2 Bolts of accuracy class B, nuts and washers should be taken:

4 The use of bolts without marking is not allowed.

5 The difference between the nominal diameters of the hole and bolts shall be taken equal to 2 mm, except for those specified in the KM drawings.

When drilling holes, use conductors or other specialized equipment that meets the quality requirements and tolerances in hole sizes. Permissible deviations from the nominal diameter and ovality - no more than +1.0 mm. The deviation of the distance between the centers of the holes in the group should not exceed 1.0 mm for both adjacent and extreme holes. The misalignment of the axes of the holes (blackness) is no more than 1.5 mm.

6 When assembling the connections, the bolt threads should not be in the hole at a depth of more than half the thickness of the element adjacent to the nut. In single-shear joints, the bolt heads should be located on the side of the thinner element, in double-shear joints - on the side of the thinner lining.

7 One round washer must be installed under the bolt heads and under the nuts.

8 The nuts must be secured against self-loosening by setting the locknuts.

Directions
for corrosion protection of steel building structures operated in non-aggressive and slightly aggressive conditions

1 General

1.1 These guidelines apply to the corrosion protection of steel building structures used in mild and non-aggressive indoor environments.

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 corrosion protection of metal structures, it is allowed to prepare the surface and priming at the plant, and the final painting at the construction 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 the work performed.

2 Surface preparation before painting

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

Previously, auxiliary elements, burrs, welding spatter, residual flux must be completely removed from the surface of metal structures, welded seams must be cleaned, sharp edges rounded off with a radius of less than 0.3 mm using a hand or power abrasive tool.

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

2.3 Cleaning the surface of newly manufactured structures from oxides should be carried out by shot-blasting or shot-blasting (sandblasting) methods up to grade 3 in accordance with GOST 9.402-80, provided that the interval from the date of manufacture of painted metal structures to heat supply in the building does not exceed 6 months and up to grade 2 - at an interval of more than 6 months. In this case, painted metal structures should be stored on wooden pads with plastic film gaskets.

The surface, cleaned to grade 2, must 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, free from oxides to grade 3, the presence of individual stripes and inclusions of rust and mill scale, occupying no more than 5% of the surface, is allowed.

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 in conditions excluding dust, oil, moisture, other contaminants and moisture condensation on the cleaned surface.

3 Application of paints and varnishes

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

3.2 The application of paint and varnish coatings should be carried out according to one of the options: option 1 - with an interval from the date of manufacture of painted metal structures to the supply of heat to the building no more than 6 months, option 2 - with 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 coating thickness is at least 60 µm.

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 coating thickness is at least 110 µm.

3.3 The application of paint and varnish coatings should be carried out at an ambient temperature of at least 15 ° C and a relative humidity of no higher than 80%, unless there are other instructions in the normative and technical documentation for each specific material.

3.4 Application of paints and varnishes should be carried out by means 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 corrosive-vulnerable places, sharp edges, corners, welds and hard-to-reach places should be painted with a brush before spraying.

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

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

4 Quality control

4.1 The used paints and varnishes must comply with the requirements of GOST or TU for these materials, have passports of manufacturers and not expired date suitability.

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

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

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

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

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

4.3 The 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 Protecting 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, as well as taking into account the following requirements: the contours of the lining, bolt heads, nuts and protruding parts of the thread of the bolts should be protected using enamel with aluminum powder in accordance with the instructions in clause 5.2.

5.2 To protect joints on high-strength bolts on the installation site, use the enamels specified in Section 3, with the initial viscosity (without solvent dilution) with the addition of aluminum powder to a consistency that excludes the enamel flowing into the package by more than 20 mm.

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

5.4 After assembling the joint on bolts without controlled tension, the assembly joints, including the bolt heads, nuts, protruding parts of the bolt threads, should be cleaned, primed, and the gaps in the places of the differences should be filled.

To protect the bolted connection, a primer used to protect the corresponding structure can be used. For the putty, use the composition according to the recipe in paragraph 5.2.

6 Safety precautions

When carrying out anti-corrosion work, it is necessary to be guided by:

SNiP 12-03-99 “Labor safety in construction. Part 1. General requirements ";

GOST 12.3.005-75 “Painting works. General safety requirements ";
