FIELD: construction.
SUBSTANCE: triangular lattice of the rod structures, besides the upper (compressed) belt, the lower (stretched) belt and the braces between them is also provided with additional semi-racks and half-braces having a Y-shaped outline. Each pair of these half-braces is connected at one end to the upper belt, and rests on the semi-rack with the other end. Wherein the upper nodal junctions of the half-braces (the upper rods of the Y-shaped racks) divide the panels of the upper belt into three parts, and the lower nodal junctions of the semi-racks (the lower rods of the Y-shaped racks) are combined with the junctions of the lower belt and the lattice braces.
EFFECT: reducing the number of nodal junctions of the lattice rod elements, reducing additional labour costs and structural material consumption.
