METHOD FOR JOINTING RAMP AND FRAME RAIL IN POINTWORK AND POINTWORK OBTAINED BY THIS METHOD Russian patent published in 2024 - IPC E01B7/02 

FIELD: pointwork structures.

SUBSTANCE: pointwork contains frame rails laid on a base and ramps interconnected by a rod with welded rail ends, having a forward direction and a side branch with a transfer curve of constant radius of curvature of the side track of 305 m. Moreover, the initial arrow angle is made equal to 0° 15' 31.31''f, and the calculated angle of impact on the ramp with a maximum gap between the wheel flange and the frame rail equal to 36 mm, when moving onto the side track is made equal to 0° 52' 49.17''.

EFFECT: reduction in the wear rate of the curved ramp is achieved.
