ISOLATING RAIL JOINT Russian patent published in 2017 - IPC E01B11/54 B60M5/00 

FIELD: construction.

SUBSTANCE: shockless isolating rail joint contains superimposed upper and lower bolted parts. The lower part from the bottom reproduces the shape of the sole of the receiving rail. In its neck section the lower part has a thickness of one and a half of the rail neck thickness, and in the top ends by the longitudinal bearing area at the height below the lower line of the rail head height by the value of thickness of electrically isolating layer. The lower part of the end face of its bottom part and the neck part is welded to the end of the receiving rail. The upper part follows the shape of the rail head width equal to the width of the bottom of the rail head and it is welded to the rail end face with the end face of its head part and with the plate welded to the sides. The upper part is split into two longitudinal halves. The electrically isolating layer of or AST-T plastic or epoxy plastic is placed in gaps between the bodies of the bolts and holes, gaps between rails and in the gaps between the lower and upper parts of the joint with the maximum thickness 10 mm.

EFFECT: design simplification and reduced specific content of metal of joints.
