ELASTOMERIC RAILROAD CROSSING STRUCTURE

摘要

A railroad crossing structure which includes a plurality of elongated center section pad members and a plurality of elongated outside field section pad members. The pad members are of width substantially the same as the center spacing between adjacent cross ties which are fastened to and span adjacent cross ties. Each pad member comprises an elongated arch member having horizontal flanges extending along each side of the arch member which is adapted for respective connection to adjacent cross ties with the longitudinal axis of the arch member disposed substantially parallel to the axes of the ties. A plurality of tension support rods are connected in chordal position across the arch of the arch member and along the flanges which are adapted to support the arch member against spreading with consequent vertical deflection when a vertical load is imposed downwardly on the arch member. A rectangular elastomeric pad body corresponding in shape to the length and width of the arch member and flanges is bonded to the upper surfaces and the arch member.
