FIELD: construction.
SUBSTANCE: invention relates to construction, namely, to triangular grid structures used for erection of power transmission towers, supports for wind generators, antennas, etc. Design of a triangular grid support includes many-sided belts with a closed section shaped by bending a steel sheet, grid rods and sheet gusset plates, shaped by reverse symmetric bending at an angle of 60° of steel sheet edges.
EFFECT: reduced steel consumption.
