TRIANGULAR LATTICE POLE WITH D-PIPE BELTS Russian patent published in 2023 - IPC E04H12/10 

FIELD: construction.

SUBSTANCE: invention can be used as support structures for antenna mast systems, lightning rods, power lines, radio relay communications, wind generators, lighting towers, chimneys and other engineering structures. The technical result of the proposed solution is to increase the possibilities of structural and layout design of bevelless lattice pole units due to one but wider flat edge while maintaining the rounded outlines of the belt elements, allowing optimization of their cross sections according to the criterion of equal stability from the axial plane and in the axial plane of the lattice. This technical result is achieved by the fact that in a triangular lattice pole made of tubular profiles, including belts and lattice rods, connected by means of welded faceless units and bolted mounting joints through flanges, the cross sections of the belts are D-shaped with an overall aspect ratio of 1.51/1 along the centre line of the design section with a design eccentricity equal to 0.25 of the smaller overall dimensions, or 2.71/1 along the centre line of the design section with a design eccentricity equal to 0.5 of the smaller overall dimensions.

EFFECT: increase the possibilities of structural and layout design of bevelless lattice pole units due to one but wider flat edge while maintaining the rounded outlines of the belt elements, allowing optimization of their cross sections according to the criterion of equal stability from the axial plane and in the axial plane of the lattice.
