Known building element, made in the form of a brace from a corner connected by bolts to the upper and lower belts by means of plate-shaped chamfers located at an angle to the belts, RU No. 2039176 C1, Е04С 3/04, 1995.07.09.

Known building modular block for the manufacture of gratings, fences, made in the form of a rectangular parallelepiped with communication elements in the form of protrusions and grooves, RU No. 2182206 C1, E04C 2/00, 2002.05.10.

Known lattice structure containing belts and rods of a triangular lattice, stamped from a strip by bending it in opposite directions with each end of the rod fastened with one shelf end to end across the belt rod, and the other lapped to the side surface of the cross section of this belt, RU No. 2159311 C1, E04C 3 / 08, 2000.11.20.

Known lattice structures have complex compounds associated with labor-intensive work and high material consumption.

Known lattice design, including the upper and lower belts, a lattice of racks having a box section and located in a vertical plane of symmetry of the cross section of the structure, and a method for its assembly, comprising connecting the upper and lower belts with racks, RU No. 2263189 C1, ЕСС 3/08 2005.10.27.

This technical solution was made as the closest analogue of the present invention, however, it has a drawback.

In the closest analogue, the connection of belts with racks made of a Z-shaped section is carried out by welding and the technology of connecting processes complicates the constructive implementation of racks and braces attached to them.

The present invention is based on the solution of the problem, which allows to increase the manufacturability of the connecting processes of structural elements, to simplify the assembly and increase the service life.

According to the invention, this problem is solved due to the fact that the lattice structure includes an upper and lower zone, a lattice of racks having a box section and located in a vertical plane of symmetry of the cross section of the structure.

The upper and lower belts and racks are made of galvanized profile in the form of channels, on the walls of the channels of the upper and lower belts there are made through grooves having a shape that is reciprocal to the profile of the racks, and equipped with tongues with the ability to move and interact with the racks, on the walls of which are in the upper and lower through their lower parts are placed through grooves, conjugated with through grooves of the upper and lower zones by means of reeds.

According to the invention, this problem is solved due to the fact that the method of assembling the lattice structure involves connecting the upper and lower belts with racks made of galvanized profile in the form of channels with the execution on the walls of the upper and lower belts of the through grooves having a shape corresponding to the profile of the racks, and provided tongues with the ability to move and interact with racks, on the walls of which in the upper and lower parts there are through grooves mated to the through grooves of the upper and lower chords stvom tongues.

The tongues are moved by bending them, each of the racks is inserted into the corresponding through grooves on the walls of the upper and lower belts until these through grooves are aligned with the through grooves of the racks in their upper and lower parts, then the tongues are bent to the fixation position of the racks in the through grooves of the upper and lower belts.

The applicant has not identified sources containing information about technical solutions identical to the present invention, which allows us to conclude that it meets the criterion of "novelty."

Due to the implementation of the distinguishing features of the invention (in conjunction with the features indicated in the restrictive part of the formula), important new properties of the object are achieved.

The presence of through grooves on the shelves and racks and the implementation of the reeds in the through grooves of the shelves increases the manufacturability of their connection.

The ability to connect shelves and racks without using fasteners by means of tongues having the ability to move and interact with through grooves simplifies assembly.

The implementation of the shelves and racks of galvanized steel extends the life of the structure.

The applicant is not aware of any publications that would contain information on the influence of the distinguishing features of the invention on the achieved technical result. In this regard, according to the applicant, it can be concluded that the claimed technical solution meets the criterion of "inventive step".

The invention is illustrated by drawings.

The lattice structure contains:

Upper belt in the form of a channel 1.

The lower belt in the form of a channel 2.

Channel bar 3.

Wall (channels 1 and 2) 4,

- through grooves (in the walls 4) 5,

- tongues (in the through grooves 5) 6.

Wall (channels 3) 7,

- through grooves (in the upper part of the walls 7) 8,

- through grooves (in the lower part of the walls 7) 9.

The lattice structure consists of upper 1 and lower 2 belts and racks 3. Racks 3 are attached to the upper 1 and lower 2 belts and are parallel to each other.

The upper 1 and lower 2 belts and racks 3 are made of galvanized profiles in the form of channels.

On the walls 4 of the channels of the upper 1 and lower 2 zones there are made through grooves 5. The through grooves 5 have a shape that is reciprocal to the profile of the racks 3. The through grooves 5 are provided with tongues 6. The tongues 6 have the ability to move and interact with the racks 3.

On the walls 7 of the channels of the racks 3 in the upper part there are through grooves 8, and in the lower part there are through grooves 9. Through grooves 8 and 9 are made respectively for the upper 1 and lower 2 belts. Through grooves 8 and 9 are interfaced with through grooves 5 by means of reeds 6.

The method of assembly of the lattice structure is as follows.

Connect the upper 1 and lower 2 belts with racks 3.

Pre-raise the tongues 6 in the through grooves 5 by bending them. Each of the uprights 3 is inserted in turn into the corresponding through grooves 5 made on the walls 7 of the upper 1 and lower 2 belts, until these through grooves 5 are combined with the through grooves 8 and 9 of the racks 3.

Then the tabs 6 are bent until the racks 3 are fixed in the through grooves 6 of the upper 1 and lower 2 belts.

The proposed lattice structure was manufactured in an industrial way; during the assembly of the experimental batch, galvanized profiles widely known in the construction industry were used, which, according to the applicant, stipulates its compliance with the criterion of “industrial applicability”.

The claimed invention allows:

- improve the technology of connection processes,

- simplify assembly

- increase the service life.
