INTERMEDIATE RAIL BRACE ON REINFORCED CONCRETE SLEEPER Russian patent published in 2011 - IPC E01B9/48 E01B9/66 

FIELD: construction.

SUBSTANCE: intermediate rail brace on a reinforced concrete sleeper comprises insert bolts (14) and two flat terminals (1 and 2) with mutually thrust and end sides (8 and 7) at different sides of a fixed rail (4). A pair of vertical contact surfaces (11, 13) is arranged on thrust sides and is intended for interaction of a terminal with its one thrust side (11) and a rail along its base (3), and with the other - with a sleeper along a vertical wall (10) of a groove (5) in the sleeper at the section (L) of the rail (4) installation. Both terminals (1, 2) are identical in size and shape and are installed in a brace unit with a turn relative to each other by an angle of 90°. Each terminal is equipped with an additional pair of vertical contact surfaces made along its end sides so that sum of distances between contact surfaces of existing and additional pairs is equal to the difference between the width of the groove (L) in the sleeper (6) under the rail (4) and the width of the base (3) of the fixed rail (4).

EFFECT: increased service life of an intermediate brace due to repeated usage of its terminals.
