The set of keys must be handed over to the customer in a sealed form against the signature of the customer (buyer). 5.7.2 The scope of delivery should include a document on quality (passport) and instructions for the operation of products, including recommendations for installation. 5.7.3 Each product is marked with a waterproof marker or label indicating the name of the manufacturer, the brand of the product, the date of its manufacture and (or) the order number, a sign (stamp) confirming the acceptance of the product by technical control. 5.7.4 The door devices included in the product must be marked in accordance with the ND for this product.

6 Acceptance rules

6.1 Products must be accepted by the manufacturer's technical control service for compliance with the requirements of this standard, as well as the conditions specified in the contract for the manufacture and supply of products. Confirmation of acceptance of products by the technical control service of the manufacturer is the execution of documents on the acceptance (quality) of products. Products are accepted in batches or individually. When accepting products at the manufacturing plant, a lot is taken as the number of products manufactured within one shift and issued with one quality document. The batch size can be taken as the number of products of the same design, manufactured according to one order. 6.2 The requirements for product quality established in this standard are confirmed by: incoming inspection of materials and components; operational production control; acceptance control of finished products; control acceptance tests of a batch of products, conducted by the quality control service of the manufacturer; periodic and certification tests of products in independent testing centers; qualification tests. 6.3 The procedure for conducting incoming control and operational production control at workplaces is established in the technological documentation. If the manufacturer completes the door blocks with components of its own manufacture, then they must be accepted and tested in accordance with the requirements of the regulatory documentation for these products. 6.4 Acceptance control of the quality of finished products is carried out by the method of continuous control. The list of controlled indicators is given in table 8. Finished products that have passed acceptance control are marked. Products that have not passed the acceptance control for at least one indicator are rejected. Table 8

* Test type I - acceptance tests during acceptance control; test type II - acceptance tests conducted by the quality service of the manufacturer; test type III - periodic tests carried out in independent test centers. ** Controlled nominal dimensions for test type II are set in the technological documentation.

6.5 Each batch of products undergoes control acceptance tests conducted by the quality service of the manufacturer. The list of controlled indicators and the frequency of control are given in Table 8. For testing, samples of door blocks are taken from a batch of products by random selection in the amount of 3% of the batch volume, but not less than 3 pcs. If there are less than 3 products in a batch, each product is subjected to control. In the event of a negative test result for at least one indicator on at least one sample, a re-check of the quality of products is carried out on a double number of samples for the indicator that had a negative test result. If a discrepancy between the indicator and the established requirements is detected again, at least on one sample, the control and subsequent batches of products are subjected to continuous control (sorting). With a positive result of continuous control, they return to the established procedure for acceptance tests. 6.6 Periodic tests according to the performance indicators specified in 5.3.1 - 5.3.7 are carried out when they are put into production or when changes are made to the design of products or their manufacturing technology, but at least once in the period specified in Table 8, and also when product certification. In justified cases, it is allowed to combine periodic and certification tests. Qualification tests of products are carried out for all indicators when putting products into production. Tests are carried out in test centers accredited for the right to conduct them. Tests to determine the reduced resistance to heat transfer, air permeability, sound insulation are subjected to structures designed to withstand these loads according to their field of application. 6.7 The consumer has the right to conduct a quality control check of products, while observing the sampling procedure and test methods specified in this standard. When accepting products by the consumer, a batch is considered to be the number of products shipped for a specific order, but not more than 90 pieces, drawn up with one quality document. 6.8 When accepting products by the consumer, it is recommended to use the one-stage quality control plan for products given in Table 9. Table 9

Note - Significant and critical defects include: defects leading to loss of performance, unrecoverable without replacing a part of the product (breakage of a steel profile, etc.), exceeding the maximum deviations of dimensions by more than 1.5 times established in the RD, disassembly of products. Minor defects include removable defects: minor surface damage, unadjusted door fittings and hinges, exceeding the limit deviations of dimensions by less than 1.5 times established in the ND. By agreement of the parties, acceptance of products by the consumer can be carried out at the manufacturer's warehouse, at the consumer's warehouse or in another place specified in the supply contract. 6.9 Each batch of products must be accompanied by a quality document (passport). An example of filling out a product passport is given in Appendix D. 6.10 Acceptance of products by the consumer does not relieve the manufacturer from liability in case of detection of hidden defects that led to a violation of the product performance during the warranty period.

7 Control methods

7.1 Methods of incoming and production operational quality control are established in the technological documentation. 7.2 Methods for quality control of products during acceptance control and acceptance tests 7.2.1 The geometric dimensions of products, as well as the straightness of the edges, are determined using the methods established in GOST 26433.0 and GOST 26433.1. Limit deviations from the nominal dimensions of product elements, the difference in the lengths of the diagonals and other dimensions are determined using a metal measuring tape according to GOST 7502, a caliper according to GOST 166, and probes according to ND. The maximum deviations from the straightness of the edges are determined by applying a calibration ruler in accordance with GOST 8026 or a building level with a flatness tolerance of at least the 9th degree of accuracy in accordance with GOST 9416 to the tested part and measuring the largest gap using probes according to ND. 7.2.2 Limit deviations from the nominal dimensions of the gaps under the overlay are checked using a set of probes or a ruler in accordance with GOST 427. mating surface to the bottom surface. 7.2.4 Appearance, quality of welds, color and quality of finishing of products are evaluated visually by comparison with standard samples approved in the prescribed manner. Surface defects visible to the naked eye from a distance of 1.5 m in natural light of at least 300 lux are not allowed. 7.2.5 Adhesion (strength of adhesion of paint and varnish coatings to the metal surface) is determined by the method of lattice cuts according to GOST 15140. packaging is checked visually. To determine the tightness of sealing gaskets, compare the dimensions of the gaps in the porches and the degree of compression of the gaskets, which should be at least 1/5 of the height of the uncompressed gasket. Measurements are made with a caliper or a ruler in accordance with GOST 427. The tightness of sealing gaskets with closed canvases can be determined by the presence of a continuous trace left by a coloring matter (for example, colored chalk), previously applied to the surface of the gaskets and easily removed after inspection. 7.2.7 The operation of the door hinges is checked by opening and closing the leaf elements of the product ten times. In case of detection of deviations in the operation of door devices, they are adjusted and re-checked.

7.3 Methods of control during periodic tests 7.3.1 The reduced resistance to heat transfer is determined according to GOST 26602.1. 7.3.2 Air and water permeability is determined according to GOST 26602.2. 7.3.3 Sound insulation is determined according to GOST 26602.3. 7.3.4 Indicators of reliability, resistance to static, dynamic, impact loads are determined according to RD and methods approved in the prescribed manner. When testing for dynamic load resistance, they simulate the load that occurs when the door leaf is suddenly opened (for example, during a draft), at the moment the door leaf contacts the slope of the doorway. The test for resistance to impact with a soft inelastic body is carried out with a three-time impact, for example, a pear with a lower diameter of (300 ± 5) mm and a mass of (30 ± 0.5) kg, from a height of fall according to 5.3.5 into the central zone of the sample. Note - At the end of the test, the door blocks must remain operational, while the bolt of the lock and the latch must freely enter their mating parts. Before and after testing the door units for failure-free operation, it is recommended to check the tightness of the seals in accordance with 7.2.6. When testing door blocks for resistance to a static load acting perpendicular to the plane of the door leaf in the free corner zone, it is recommended to use the graph of dependence of the deflection of the free corner of the door leaf on the applied load given in Appendix D. 7.3.5 Quality control methods for welded joints (5.3. 10) are installed in the manufacturer's technical documentation in accordance with GOST 5264.

8 Packaging, transport and storage

8.1 Packaging of products must ensure their safety during storage, handling and transportation. 8.2 Devices or parts of devices that are not installed on the products must be packed in polyethylene film in accordance with GOST 10354 or in other packaging material that ensures their safety, tightly tied and delivered complete with products. 8.3 Opening webs of products before packaging and transportation must be closed on all locking devices. 8.4 Products are transported by all means of transport in accordance with the rules for the carriage of goods in force for this type of transport. 8.5 During storage and transportation of products, they must be protected from mechanical damage and exposure to precipitation. 8.6 When storing and transporting products, it is recommended to install gaskets made of elastic materials between products. 8.7 Products are stored in a vertical or horizontal position on wooden linings, pallets or in special containers in covered areas. 8.8 Warranty period of storage of products - 1 year from the date of shipment of products by the manufacturer.

General requirements for the installation of products

E.1 The requirements for the installation of products are established in the design documentation for construction sites, taking into account the design options adopted in the project for the junctions of products adjoining walls, designed for specified climatic and other loads. E.2 Installation of products must be carried out by specialized construction companies or specially trained teams of the manufacturer. Completion of installation work must be confirmed by an acceptance certificate, which includes the manufacturer's warranty obligations. E.3 At the request of the consumer (customer), the manufacturer (supplier) of products must provide him with a standard instruction for the installation of door blocks, approved by the head of the manufacturer and containing: drawings (diagrams) of typical mounting junctions; list of materials used (taking into account their compatibility and temperature conditions applications); the sequence of technological operations for the installation of door blocks. E.4 When designing and executing junction nodes, the following conditions must be met: sealing of mounting gaps between products and slopes of openings of wall structures must be tight, tight around the entire perimeter of the door block, designed to withstand climatic loads outside and operating conditions inside the premises; the design of the junctions of external products (including the location of the door block along the depth of the opening) should prevent the formation of cold bridges (thermal bridges) leading to the formation of condensate on internal surfaces as much as possible doorways; the operational characteristics of the structures of the junction points must meet the requirements established in building codes. A version of the mounting assembly of the internal door unit is shown in Figure E.1.

E.5 The number and location of the mounting ears, the type, diameter and length of the fasteners are set in the working design documentation, taking into account the material of the walls and the design of the doorway. It is recommended to use building anchors with a diameter of at least 10 mm as fasteners for the installation of products. The distance between fasteners is at least 700 mm. It is not allowed to use sealants, adhesives, foam insulation, as well as building nails for fastening products. E.6 Door blocks should be installed according to the level and plumb. The deviation from the vertical and horizontal profiles of boxes of mounted products should not exceed 1.5 mm per 1 m of length, but not more than 3 mm for the height of the product. At the same time, if the opposite profiles are deflected in different directions (“twisting” of the box), their total deviation from the normal should not exceed 3 mm. The door block is installed in the prepared doorway symmetrically with respect to the central vertical of the opening. The deviation from symmetry should not exceed 3 mm in the direction of the slope of the opening, intended for fastening the profile of the box with hinges. Deviation from symmetry to the other side of the opening is not recommended. E.7 To fill mounting gaps (seams) of external products, mounting foam, silicone sealants, pre-compressed PSUL sealing tapes (compression tapes), insulating polyurethane foam cords, foam heaters, mineral wool and other materials that have a hygienic conclusion and provide the required performance of the seams are used . Painting seams is not recommended. E.8 When arranging assembly joints and installing external door blocks, it is recommended to take into account the requirements of GOST 30971.

The subject of the material presented by us below was GOST for steel doors equipped with locking devices and installed in industrial and civil buildings. The only thing that this standard does not cover is doors, which are subject to special requirements: resistance to aggressive substances, explosion resistance, bulletproofness and fire safety.

The use of all other products, which the video in this article will also tell about, depends on the conditions of their operation, and is regulated by GOST doors 31173.

Steel doors GOST 31173 2003 are classified according to six main features. First of all, this, of course, is the purpose, as they can be: street, internal and vestibule. And internal doors can be entrance apartment doors, and operated as an ordinary interior door.

Structural differences

The second feature determines the design of the door unit. Here the difference may be in the box, since it is closed; is the shape of the letter "P"; or completed with a threshold, which is an additional element.

The next classification feature concerns the number of canvases and options for opening them. The most common doors with one leaf - left or right opening. Next come the canvases of which can be either the same or have different widths.

- most often these are ceremonial models, they can also be decorated with inserts. This is either a rectangular or semicircular transom, located horizontally above the opening, or narrow non-opening canvases on the sides of the canvas. This is exactly what we see in the photo above.

Doors are also distinguished by the direction in which they open: outward or inward. It also matters how many sealing circuits are located in the porch. There are usually two of them, but there may be more.

Facing options and performance

The fourth sign by which steel doors GOST 31173 2003 are classified is their front finish.

There are seven options here:

Number one is paint.- both traditional and powdered. These are the most popular finishes (see): in the first case, the main criterion for choosing products by the consumer is a low price, and in the second, the incredible strength of the coating, which has already been called anti-vandal.
Next come the options with natural or artificial leather lining and insulation; decoration with film coatings; facing with wood roll or board materials (veneer, MDF lining). By the way, many of these types of finishes can be done on old or do-it-yourself doors.

Note! For all types of polymer coatings used for decorating doors, the manufacturer must provide a conclusion confirming their sanitary safety.

Glass or mirror finishes look very nice on the doors, especially the front doors.. Alternatively, the canvas is ennobled with a metal overlay with beautiful milling or engraving, or several finishing methods are combined in one model. In general, having coordinated its actions with the customer, the manufacturer can perform any other type of decor - even gilding.

With regard to thermal properties, according to GOST, steel exterior doors are divided into three classes according to heat transfer resistance. At a minimum, this indicator should be 0.4 m2 * C / W.

Anything less is not classifiable. The highest class is with a heat transfer resistance of more than 1 m2 * C / W. There is also a table in the standard, which presents the desired indicators of breathability and water resistance.

Soundproofing for steel doors is of no less importance. There are also three classes, the division of which is carried out according to the level of noise reduction.

Indicators less than 20 decibels are not subject to classification. The third class is the lowest, with indicators up to 25 dB, in the second class up to 31 dB, but the first class is more than 32 dB.

Mechanics and protective qualities of products

The standard for doors made of metal also presents a table with strength indicators, which are also divided into three classes. In total, there are five different characteristics in it, according to the value of which the doors belong to one or another class. It is set according to the worst test result.

This is the resistance to static loads acting in the plane of the web; perpendicular to the canvas; and in the loop area. It also regulates the level of resistance to dynamic impact in the direction where the canvas opens, and to impact in both directions.

By security properties, doors are classified as follows:

Standard doors. They are equipped with locking mechanisms of at least the third class (M3), and anti-removable pins.
Reinforced blocks. Here, reinforced door hinges are added to the above, and locks with a large number of crossbars, which can lock the door around the entire perimeter of the porch. Their strength must correspond to the second class (M2).
Security door blocks. These are all the same reinforced blocks, but the characteristics of the locks installed in them must correspond to the first class of strength (M1).

You can also find out whether the doors are reinforced in front of you, or protective, by their marking. The corresponding letter "U" or "Z" is simply added to it. In general, this standard recommends that manufacturers indicate all the data mentioned above in the product passport. They are also encrypted in the marking.

Information should include: design solution; the option of filling the canvas and its front finish; dimensions; lock class. The passport must be accompanied by a scheme for opening the canvas or canvases, as well as instructions for installation and operation of the product.

Requirements for steel doors

Paragraph five of the standard we are discussing, voices a list of requirements that apply to door blocks made of steel. Among the general provisions, information is given that the canvas is a welded structure, for the manufacture of which steel sheets or bent profiles are used.

Welding is a mandatory connection of parts. Other types of joints are permissible only if, in terms of strength characteristics, they are ahead of welded ones - but this, in general, is unlikely. With regards to the design solutions of canvases, the standard presents four main options.

Structural types of canvases

The first option is as follows: the canvas is made on a frame of profiles with a closed hollow section, and two steel sheets are welded to it. In this case, the filling of the canvas is used honeycomb (corrugated cardboard, or hardboard). The second type of metal doors looks like a bent box mounted on profiles with a U-shaped section. Inside, such canvases are filled with polystyrene foam.

In the third variant, the leaf frame is welded from profiles of a more complex section, filled with mineral insulation, and closed from the outside with a steel sheet, and from the side of the room with sheet wood material - for example, solid fiberboard. This is the type of door you see in the picture below.

The fourth option is also combined: the frame, filled with foam, is made of wooden bars - and only its edges are protected with an angular steel profile. The outer and inner sides, as in the third case, are closed on one side with a steel sheet, and on the other side with a wood-fiber sheet.
Regardless of the design option, mullions should be used in the canvases - stiffeners that reinforce the frame of the canvas. They can be not only vertical or horizontal, but also inclined. It is mandatory to reinforce loop zones, as well as places where anti-removable pins are installed.
In the manufacture of metal sheets, the standard allows facing the inside not with a solid steel sheet, but with cut blanks welded together along a profile that reinforces the seams. A hatch must be provided on the inner sheet, which is necessary for repairing the lock or latch.

Locking mechanisms, which include not only locks and latches, but also latches, are mounted on special linings, screws and threaded clamping brackets. Welding is not used in this case, since in its process it is easy to spoil some parts of the lock.
Holes into which the deadbolt or bolt of the lock enters must be protected by a metal box, which is welded into the frame profile. The entry of the deadbolt when closing the lock must be free - and for this, the size of the hole must be at least 2.2 cm larger than the cross section of the deadbolt.
The proper level of sound insulation is achieved by installing two sealing contours. Gaskets are mounted around the entire perimeter of the web, avoiding the slightest gap. If the door unit is intended for outdoor installation, then the seals must be resistant to moisture and temperature changes.

It should be noted that there are some restrictions on the doors according to GOST 31173 2003 - namely, their dimensions and weight. The following indicators should not exceed:

height: 2.2m
in width: 1.2m
by canvas area: 9m2
by web weight: 250kg

For doors manufactured in excess of the above standards, additional calculations are made, and their compliance with the requirements of the standard is confirmed by the results of individual tests.

In order to remove the canvas closed door it is impossible to make it impossible from the hinges, the design of the product provides for fixed crossbars, or, as they are called, anti-removable pins. They are mounted on the frame of the canvas, and fastened by welding, riveting, or pressing.
The size of the pins, their number and location must be indicated in the working drawings. But most often they are provided next to the loops, as this is the most reliable option.

In order for the door frame to be installed in the opening, details are welded to its profile, which are called mounting ears. Other solutions directed by the manufacturer to ensure the strength of the installation of the unit are also allowed.

Dimensions and tolerances

About what should be the maximum dimensions in height and width, it has already been said above. In general, metal doors, like any other, are made in standard versions.

If this is a single-leaf door, then the most running dimensions: for the front door 2.1*0.9m, for the inner door 2.0*0.8m. Although, of course, the options may be different. In any case, both the dimensions and the drawings applied to the canvas are necessarily reflected in the technical documentation of the product.

In addition to the dimensions of the door itself, it reflects the sections of the profiles, the detailed dimensions of the nodes and gaps. The drawings indicate the locations of the locking devices, holes for them, and loops. The standard also contains a table that defines the maximum allowable deviations from dimensional intervals.
In general terms, 3 mm is the maximum that is allowed only by internal size boxes over 2m high. The minimum is allowed for the outer dimension of the web, which is 1 mm / 1000 mm. In the gaps under the overlay, there should not be a difference of more than 1.5 mm.

The manufacturer must control the length of the diagonals, the sag of the front skins, and the straightness of the edges of the frame and canvas with the same care. All geometric parameters are calculated taking into account the design features of the product, the technology of its installation, and in accordance with the standard 21778, which has been in force since 1981.
GOST, which is discussed in this article, imposes requirements both on the materials used in production, components and seals, and on finished products. In particular, steel elements must be free of warps, cracks, cavities, dents and rust. Although a slight waviness that does not damage the aesthetics of the product as a whole is allowed.

Delivery of the steel door block is carried out assembled with a locking device. This is mandatory - but such components as a peephole, an opening angle limiter, a door closer are installed by additional agreement of the customer. The product must have a label, or a marker inscription, informing which manufacturer, when, and for what order it was manufactured. Also, the block must be marked and stamped by the department that carried out the technical control.

Fire doors are a necessary element of security in industrial enterprises, in shopping and office centers. They allow you to delay the penetration of an open flame into a room with people. Even with a strong fire, such doors do not deform for at least 30 minutes and do not become an additional source of toxins. They are also installed in private houses and apartments, so that in extreme conditions the owners of the dwelling have a chance to get out of the room or wait for help from firefighters. V high-rise buildings it is the fire door that may be the only chance for salvation. It plays an important role in fire suppression and evacuation of people from the scene.

Basic GOSTs

Requirements for a fire door are indicated in GOST, which indicates the fire resistance limit and other basic characteristics. Compliance with these standards provides protection against the penetration of flame and smoke into the room. To obtain a certificate confirming compliance with the necessary parameters of GOST, it is necessary to conduct laboratory tests. The EIR marking shows the limit of structural integrity, thermal insulation properties and the time until the door ignites.

Classification of doors by types according to GOSTs

Fire doors are classified into three types:

Manufacturing material. They are made from wood, metal and glass. The latter allow you to see the source of ignition and the strength of the fire. Metal doors according to GOST can also be made of steel or aluminum. For each type, there are standards that the design must strictly comply with.
Construction type. They are divided into single-sided and double-sided. Single-leaf structures consist of a box and a door leaf that opens only in one direction. In this case, the main requirement is to set the threshold. Double-leaf doors can be either equal or unequal, depending on the width of the leaves. It is important to remember that the leaves of double-leaf doors should open in one direction.
Degrees of fire resistance. Products come in three types: 1st, 2nd, 3rd. The fire resistance of doors mainly depends on the thickness and type of the inner insulation layer.

Dimensions according to standards

Dimensions GOST regulates the verification of one standard size of doors for a particular manufacturer. The protocol records the test results and dimensions, tolerance which in height and width should not exceed +10% and -30%. The value is only rounded up to 5 cm up and down to 10 cm.

Permits for installation

Fire doors may only be installed in suitable rooms. Since the main function of such structures is to protect people and property from fire, they are often mounted in rooms with an increased likelihood of fire. In industrial enterprises, these are warehouses, corridors, workshops, basements, attics and technical compartments. If the total area of the technical floor exceeds 300 m2, two fire-resistant structures must be installed, while the size of the doors should not be less than 0.75 * 1.5 m. In office centers, such doors are installed in rooms where important documents are stored.

According to consumers, a metal fire door has the highest degree of fire resistance. GOST obliges to use grades of alloyed steels for manufacturing. Non-toxic refractory materials are used as coatings and heaters. Wooden structures, which were previously impregnated with special solutions that slow down the fire, also have sufficient fire resistance. Modern technologies make it possible to use aluminum profiles with thermal storage fillers and laminated refractory glass for the production of doors.

There is no regulatory document regulating the installation of a fire-resistant door. However, for the installation of a fire-fighting structure, a package of documents is required. It consists of a fire safety certificate, a passport for the door and a license to perform door installation work. You also need a well-established door closer that automatically closes the door. A special non-combustible fire-fighting foam must be used for installation. The metal structure should fit snugly against the box, leaving no gap. To ensure the reliability and durability of the door, the sealing rubber should be slightly compressed. Uniform painting, high-quality glued thermal expansion tape, and an adjusted closer will serve as a guarantee of high wear resistance of the structure.

Fire door operation

Caring for fire doors is no different from servicing a conventional metal structure; it is not regulated by GOST. The operation of both wooden and steel doors must be carried out throughout the specified service life. According to GOST standards, a door that has fulfilled its main protective function during a fire is subject to replacement. After that, the fire-resistant fire door is dismantled and replaced.

Fire doors made in accordance with GOST , are more expensive than conventional doors, but they provide security in case of fire. Even if the fire department does not require the installation of such a door, it costs much more than the additional money spent. This design can save not only property, but also people's lives.

If the residual deformation fits into half of the gap between the leaf and the frame (in the lower and vertical parts of the door in the area of the free corner) or is completely absent, the door passed the test.

8.2 Resistance to static load applied in the area of the free corner of the door

blades perpendicular to its plane

B.2.1 When determining the resistance to a static load applied in the plane of the door leaf, the load (successively from smaller to larger) is applied in the direction of opening the door leaf (in this case, the door must be closed on all locks) 8 in the free corner zone (the application point is set) in within 5 min.

B.2.2 After removal of the load, the presence (or absence) of permanent deformation is revealed. If the permanent deformation (in the area of the free corner) does not exceed 1/5 of the thickness of the seal (see 7.2.6). The door passed the test. Otherwise, a gap will open for the passage of air and the indicators of sound insulation and resistance to burglary will decrease.

B.3 Resistance to static load applied perpendicularly in the hinge area

door leaf plane

B.3.1 When determining the resistance to a static load applied in the hinge area perpendicular to the plane of the door leaf, the load (successively from smaller to larger) is applied in the direction of opening the band (the door must be closed with all locks) in the area of each hinge (application points are given ) within 5 min.

B.3.2 After removal of the load, the presence (or absence) of permanent deformation is revealed. If the permanent deformation in the area of each hinge does not exceed 1/5 of the thickness of the seal (see 7.2.6), the door passed the test. Otherwise, a gap will open for the passage of air and the indicators of sound insulation and resistance to burglary will decrease. Schemes for applying dynamic loads are shown in Figures B.1-B.3.

General requirements for the installation of door blocks

D. 1 The requirements for the installation of door blocks are established in the design documentation for construction sites, taking into account the design options adopted by the 8th project for the design of the junctions of products to the walls, designed for given climatic and other loads.

D.2 Installation of door blocks should be carried out by specialized construction companies or specially trained teams of the manufacturer. Completion of installation work must be confirmed by a kg o * i of acceptance, including the warranty obligations of the manufacturer of the work.

D.3 At the request of the consumer (customer), the manufacturer (supplier) of door blocks must provide him with a standard installation instruction approved by the head of the manufacturer and containing:

Drawings (schemes) of typical mounting junctions:

List of materials used (taking into account their compatibility and temperature conditions of application);

The sequence of technological operations for the installation of door blocks.

D.4 When designing and executing junction nodes, the following conditions must be met:

The sealing of the mounting gaps between the products and the slopes of the openings of the wall structures must be tight, tight around the entire perimeter of the door block, designed to withstand climatic loads from the outside and operating conditions inside the premises:

The design of the junctions of external products (including the location of the door unit along the depth of the opening) should prevent the formation of cold bridges (thermal bridges) as much as possible, leading to the formation of condensate on the internal surfaces of doorways:

The operational characteristics of the structures of the junction points must meet the requirements established in the building codes and regulations in force on the territory of the state party to the agreement that adopted this standard.

A version of the mounting assembly of the internal door unit is shown in Figure D.1.

D.5 Quantity and location of mounting "lugs", view. the diameter and length of the fasteners are set in the project documentation, taking into account the material of the walls and the design of the doorway. It is recommended to use building anchors with a diameter of at least 10 mm as fasteners for the installation of products. The distance between fasteners is at least 700 mm.

It is not allowed to use sealants, adhesives, adhesives, as well as building nails for fastening products.

D.b Door blocks should be installed according to the level and plumb. Deviations from the vertical and horizontal profiles of boxes of mounted products should not exceed 1.5 mm per 1 m of length, but not more than 3 mm for the height of the product. If the opposite profiles are deviated in different directions (“twisting into boxes), their total deviation from the normal should not exceed 3 mm.

The door block is installed in the prepared doorway symmetrically with respect to the central vertical of the opening. The deviation from symmetry should not exceed 3 mm in the direction of the slope of the opening, intended for fastening the profile of the box with hinges. Deviation from symmetry to the other side of the opening is not recommended.

D.7 To fill the mounting gaps (seams) of external products, mounting foam, silicone sealants, pre-compressed sealing tapes (PSUL) (compression tapes), insulating polyurethane foam cords, and flax heaters are used. mineral wool and other materials that have a hygienic conclusion and provide the required performance of the seams.

D.8 When arranging assembly joints and installing external door blocks, it is recommended to take into account the requirements of GOST 30971.
