Measures for fabrication, durability of wooden structures and fire safety

Glued structures shall meet a number of technical requirements:

1. Wooden glued structures shall be manufactured in accordance with the requirements of the standard according to the working drawings approved in accordance with the established procedure. Structures must also comply with the requirements of state standards or specifications for specific types of design.

2. The structures shall be supplied to the customer in package; The package shall include elements and parts prepared for installation.

In agreement with the customer, the assembly and installation site can be completed.

3. Limit deviations of linear dimensions of structures, deviations from rectilinearity, flatness, perpendicular of adjacent surfaces, axis splitting, as well as inequality of diagonals of enclosing structures must comply with GOST 21779 and be indicated in state standards, specifications or working drawings on structures of specific types.

4. For the manufacture of glued structural elements, pine or spruce lumber should be used according to GOST 8486 with dimensions according to GOST 24454. It is allowed to use sawn timber of other rocks in the presence of specifications that take into account the specifics of the manufacture and operation of structures.

5. The moisture content of wood structures during their manufacture and acceptance shall be within (12 ± 3)%.

6. Adhesive joints in structures should be made on synthetic adhesives corresponding to SNI25. Non-glued areas are not allowed.

7. Thickness of adhesive layers in structural elements shall not exceed 0.5 mm. Sections up to 1 mm thick are allowed, if their length does not exceed 100 mm, and the distance between them is not less than 10 times the length of these interlayers.

8. The maximum height of irregularities on the side surface of the layers with transparent protective or decorative coatings should be no more than 320 μm, and with opaque - no more than 800 μm.

9. Protective and decorative treatment of structures required to protect them from humidification, bio-damage, fire and chemical corrosion, as well as to give them the necessary aesthetic appearance, must be carried out at the manufacturer.

At the same time, protection is possible from both one and a complex of these impacts, which should be regulated by the requirements of working drawings or specifications, based on the operating conditions of the structures. The type and characteristics of protective coatings, as well as the rules for their acceptance and control methods should be indicated in the specification.

Structural requirements for ensuring the reliability of wooden structures

1. Structural measures and protective treatment of wood should ensure the safety of wooden structures during transportation, storage and installation, as well as their durability during operation.

2. Structural measures shall include:

a) protection of wood structures from direct humidification by atmospheric precipitation, soil and meltwater (with the exception of supports of overhead power transmission lines), production water, etc.;

b) protection of wood structures from freezing, capillary and condensation humidification;

c) systematic drying of wood structures by creating a drying temperature-moisture regime (natural and forced ventilation of the room, device in structures and parts of buildings of drying products, aerators).

3. Wooden structures shall be open, well ventilated, as far as possible accessible in all parts for inspection, preventive repair, resumption of protective treatment of wood, etc.

4. Blind sealing of parts of wooden structures into stone walls is not allowed.

5. Load-bearing glued wooden structures used outdoors shall have a continuous section; the upper horizontal and inclined faces of these structures should be protected with antiseptic boards, visors made of galvanized roofing iron, aluminum, fiberglass or other weatherproof material.

6. Support of bearing wooden structures on foundations, stone walls, steel and reinforced concrete columns and other elements of structures made of more thermally conductive materials (with their direct contact) should be carried out through waterproofing gaskets.

Wooden liners (pillows), on which supporting parts of bearing structures are installed, should be made of antiseptic wood, mainly hardwood.

7. Metal linings in joints of structures operated under conditions where condensate precipitation is possible shall be separated from wood by a waterproofing layer.

8. Coatings with wooden bearing and enclosing structures should be designed, as a rule, with an external water drain.

9. To prevent fire hazard, wood of structures should be impregnated with flame retardants. The characteristics of flame retardants are different, so the choice of flame retardant should be determined from the conditions of operation and purpose of the building. It should be borne in mind that flame retardant significantly changes the strength characteristics of wood .
