摘要
The present invention relates to a concrete track structure capable of reducing interaction between a concrete track and a bridge to minimize additional strength induced by difference of temperature expansion between the concrete track and a bridge bottom plate, and a railroad bridge in which a concrete track is constructed by a concrete track structure. According to the present invention, the railroad bridge includes a bridge upper structure having the bottom plate and a concrete track unit installed on the bottom plate. The concrete track unit comprises: a rail on which a railroad vehicle is directly driving; a slab-shaped concrete track to which the rail is fixed, wherein the concrete track is located in the lower part of the rail; and a slide layer arranged between the upper surface of the bottom plate and the lower surface of the concrete track in order for the concrete track to slide in the axial direction of the bridge. Therefore, even if the longitudinal displacement is induced by the thermal expansion of an upper structure of the bridge, the longitudinal displacement is not transmitted to the concrete track. In addition to this, the present invention provides a concrete track structure constructed in the railroad bridge.;COPYRIGHT KIPO 2016
