MULTI-FACETED PILLAR OF A POWER POLE Russian patent published in 2019 - IPC E04H12/08 

FIELD: construction.

SUBSTANCE: invention relates to construction, in particular, to power poles, telecommunication antennas, cellular communication towers, electric lighting racks and other supports. Multi-faceted pillar of a power pole is proposed, containing at least one pair of telescopically coupled hollow polyhedral sections, in which the upper part of the lower section adjoins from the inside to the lower part of the upper section, a flange with holes for passage of coupling bolts attached by welding to the end of the lower section, and a diaphragm stiffness, fixed by welding inside the upper part of the lower section and made in the form of a ring with a multi-faceted outer contour corresponding to the inner contour of the upper part of the lower section. Pillar is equipped with a hollow truncated pyramid covering the lower part of a multi-faceted support column having an equal number of faces, the smaller base of the truncated pyramid is welded to the outer surface of the lower part of the upper section at the level of fixing the stiffness diaphragm inside the lower section, and its larger base is welded to the flange along its outer contour, and coupling bolts are installed in the flange holes, the heads of which are welded to the outer surface of the flange.

EFFECT: technical result achieved with the implementation of the invention consists in increasing the rigidity, strength and carrying capacity of the supports of a power pole.
