FIELD: construction.
SUBSTANCE: invention relates to the field of construction, in particular, to assemblies of connection of rods in a grid structure, for example, to trusses made of paired cold-bent profiles connected in assemblies by means of a sheet gusset plate on bolts. Purpose of the invention is achieved by the fact that a unit for connection of bars of the mesh structure, belts and grids of which are connected in units with sheet gusset plates on bolts, note here that, in said compressed elements with flat concave wall, reinforcing element is arranged at said point to eliminate gap between profile wall and sheet gusset plate. Reinforcing element is made for each bolt in the form of a solid single bushing inserted into the through hole of the sheet gusset plate. Total height of sleeve is equal to thickness of the sleeve and double free thickness of flat concave profile wall.
EFFECT: invention objective consists in reduction of steel consumption on sheet gusset plate.
