Steel connecting device for railroad ties for rail-bound traffic routes, in particular of prestressed concrete - switch cross ties

摘要

Connecting device (3, 11, 21, 31, 41) for concrete sleepers several sections for railway infrastructure communication, preferably for sleepers needle, whereby at least two sections (1, 2) of cross prefabricated are coupleable longitudinally, with the possibility of disassembly, it forming a unitary cross through structural steel construction, wherein said unitary cross, formed by the union of sections of cross, is equivalent to a sleeper of a part in regard to the transmission of bending moments, shear forces and normal forces.
