LONG-LENGTH BEARING STAND OF POWER LINE Russian patent published in 2015 - IPC E04H12/08 

FIELD: construction.

SUBSTANCE: long-length bearing stand of power line contains two lateral sides with stiffening ribs each, made from bent metal sheets and forming open trapezoid cross section. Each lateral side is implemented in extended form plan view and has the stiffening rib unbent from it along one edge side inclined at obtuse or acute angle to the lateral side surface. Each lateral side with stiffening rib is made from integral sheet with the rack height, or several sheets, welded among themselves, in which the stiffening rib is formed by bending of edge part from one side of this sheet. Meanwhile two lateral sides from another side are located at a distance from each other and connected among themselves by the connecting elements spaced along the rack height at the distance between each other for formation of through windows or apertures between edge parts of lateral sides, and from the side of stiffening ribs the lateral sides are connected among themselves by brace struts.

EFFECT: improvement of mechanical characteristics due to decrease of aerodynamic resistance along the plane where the brace struts connecting stiffening ribs of lateral sides are located.
