Kind Code:
A1
Abstract:
Provided are a ballastless track base plate connecting structure and a ballastless track having the same. The connecting structure comprises a first connecting body and a second connecting body, wherein the first connecting body is provided at an end part of a first ballastless track base plate and comprises a protruding part protruding along the longitudinal direction, and a bolt hole penetrating through the surface of the first connecting body is provided at a longitudinal end face of the protruding part; and the second connecting body is provided at an end part, correspondingly connected to the first ballastless track base plate, of a second ballastless track base plate, and a recessed part extending along the longitudinal direction and matching the protruding part is provided on the second connecting body, and a bolt hole penetrating through the surface of the second connecting body is provided at a longitudinal end face of the recessed part. With the optimized and improved connecting structure being provided on the ballastless track base plate, the problem that a base plate is prone to being deformed when under stress and arches upward during connection can not only be overcome, but the connecting structure is also simple in structure, convenient to construct, and reliable and simple to disassemble, assemble and maintain in the later period.
