Steel lattice pole for hanging and anchoring traction mains of railway tracks is adapted for detachably mounting to the bolt of base structure. Its four stanchions (1) of the L-shaped profiles are along interconnected with gradually sloping one above the other arranged crossbars (2) L-shaped profile and build a lattice body of pole tapering toward the upper end, where each of the stanchions (1) is equipped with plate foot. Each plate foot (3) consists of a rectangular plate of sheet steel, which has towards the center of the lattice body of pole a beveled corner and has three through-holes (5) to attach the pole to bolts of the base structure. One hole (5) is located in the beveled corner plate foot (3) and the other two are situated symmetrically to it by two exterior walls of plate foot (3). Each stanchion (1) is in the area of lower end equipped with plate reinforcements (4) in the form of a right triangle, welded to the corresponding plate foot (3), as well as to the stanchion (1), where the reinforcement (4) is oriented diagonally in the rectangular plate foot (3) in the direction of the beveled corner, passes between the holes (5) and interfere with the edge plate foot (3) in its corner. Steel gate structure includes a horizontal supporting girder (7), creating of lattice structure, composed of four corner-posts (8) L-shaped profile, interconnected with crossbars (9) of the belts. The body of the pole is adapted to attach the end part of a girder (7) by bolts or for placing end part of girder (7) freely on a steel chair (10), attached to the body of the pole by bolts or welded to it. |
