RAIL BRACE ANCHOR Russian patent published in 2013 - IPC E01B9/00 E01B9/30 

FIELD: construction.

SUBSTANCE: rail brace anchor comprises a tail embedded into a sleeper, a wall that limits side displacement of the rail, comprising a cavity for fixation of a terminal bar in the vertical plane and a support at the sleeper. The front plane of the anchor wall is made at the angle α=0-10° to the vertical plane, parallel to the longitudinal axis of the rail. The cavity for fixation of the terminal bar with an electric insulator in the vertical plane comprises two vertical slots with inclined inner walls with horizontal T-shaped clamps that make at least 0.6 of diameter of the spring terminal bar for its fixation, and a longitudinal slot for placement of the device of spring terminal fixation by its vertical movement into the anchor. The support against the sleeper comprises seating surfaces for installation of the wedge and control of the force of rail pressing to the sleeper and seating surfaces for installation of the wedge and control of the distance between rails of the railway track.

EFFECT: expanded functional capabilities of a rail brace due to provision of the possibility of terminal installation jointly with an insulator and control of rail pressing force, and simplified installation of a terminal into a rail brace anchor.
