TRIANGULAR LATTICE SUPPORT Russian patent published in 2019 - IPC E04H12/10 E04C3/32 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to lattice structures used in construction of supports of overhead transmission lines, supports for telecommunication antennas, wind-driven plants, etc. Triangular lattice support comprises three belts of closed polyhedral cross-section, connected along edges by rods of lattice. Each belt includes a post made of two angles, vertices of which along length are connected on welding, with location of their adjacent shelves directed inside the support at angle of 60° to each other, and adjacent shelves directed outward supports, respectively at angle of 120° to each other. To ends of adjacent shelves directed inside and outside the support, by longitudinal seams, two steel strips are welded, with formation of belt of closed polyhedral cross-section, which is two trihedral structures, having common rib in place of welding along length of tops of angles, first of which is located inside, and second is outside the support, wherein two faces of each of them are made of adjacent shelves of corners, located respectively at angles of 60° and 120° to each other, and their third faces are formed from steel strips, wherein rods of the lattice are attached to adjacent angles of angles located at angle of 60° to each other.

EFFECT: technical result achieved when realizing the invention consists in reduction of labor intensity and cost of making the support, as well as increase in its strength.
