Sliding slab track for railway bridge and construction method of sliding slab track for railway bridge

摘要

The present invention relates to a sliding track for a railroad bridge and a method for constructing a sliding track for a railroad bridge, which comprises means for suppressing lateral stress deformation of a sliding slab and a sliding slab which are separated from a railway bridge top plate without damaging the railway bridge top plate. A sliding orbiter plate formed of a concrete slab formed on the upper portion of the bridge and formed on the upper surface of the concrete slab and elongated in the direction of the axis of the bridge, the bridge being adjustable with respect to the upper bridge of the railway bridge; A first friction reducing layer formed of a first friction reducing member and a second friction reducing member attached to an upper surface of the bridge top plate; and a rigid bracket disposed in close contact with both side surfaces of the sliding raceway plate, As a lateral support block fixed by a fastening member The lateral deformation of the sliding orbital plate can be effectively suppressed while the influence of the displacement due to the expansion and contraction of the railway bridge top plate to the sliding orbital plate is blocked and the damage to the bridge top plate can be minimized, And to provide a method of constructing a sliding track for a railway bridge and a method of constructing a sliding track for a railway bridge, in which installation time and effort are minimized since the assembly can be assembled in the field in advance.;
