1.2 Relevance and novelty of elements

The design of the building for the manufacture of light metal building structures is due to the fact that at present the direction of "buildings from light metal structures" has been widely used in construction. These can be: warehouses, production shops, shopping complexes, sports facilities, administrative and household complexes, hangars of all kinds (for aircraft, cars, military and agricultural equipment, etc.).

Modern technologies make it possible to manufacture frame elements with high accuracy, thereby reducing the time and simplifying the installation process of metal structures, while ensuring high reliability and durability.

The further development of the theory and methods of calculating reinforced concrete structures is due to the desire to reduce their material capacity while ensuring the necessary reliability, use new materials, change the characteristics of structures and expand their areas of operation under various operating conditions and impacts. In industrial construction, the promising direction is the design of large-span buildings with an enlarged column grid and large-sized enclosing structures when unifying volume-planning solutions and the use of standard structures.

The decrease in material capacity of reinforced concrete structures is largely due to the improvement of structural shapes and the use of high-strength concretes and steels. The structural layout of the building is also being improved.

One of the main areas of design and construction of industrial buildings is the use of efficient construction materials that reduce the material capacity of industrial construction.

In this project, during the design, special attention was paid to the selection of materials and roof design.

The reliability of the roof depends on the following factors:

- correct roof design, depending on the extent to which operating conditions were taken into account during its design;

- competent selection of materials from which this roof will be made; at the same time, it is important that the supplied materials comply with the declared specification, this is the purpose of certification of products in the GOST R system and more complex international certification for compliance with the requirements of ISO 9002.

In this project, a roof made of bitumen-polymer materials with insulation from mineral wool plates is used.

Roofing bituminous and bituminous polymer materials consist of a base (cardboard, glass cloth, glass fabric, polyester nonwoven fabric - polyester), on which bituminous or bituminous polymer binder is applied.

The upper side of the materials intended for the upper layer of the roof carpet is covered, as a rule, with coarse-grained sprinkling. To prevent sticking, polyethylene film is increasingly used, which is coated with the lower or both sides of the material.

Water removal from coatings is accepted as internal.

To remove vapors from the roof structure, roof fans (aerators, vanes) are installed.

Architectural part
