STEEL DECK REINFORCEMENT SLAB BRIDGE AND CONSTRUCTION METHOD THEREFOR

摘要

The present invention relates to a steel deck reinforcement slab bridge which ensures structural stability by reinforcing a connection portion (sub-moment portion) for an upper structure through an increase in the rigidity of a lower structure, and a construction method therefor. According to the present invention, the steel deck reinforcement slab bridge comprises: a foundation portion; a lower structure (100, 200) including a concrete wall and an anchor installed in the concrete wall such that a head portion thereof protrudes therefrom; and an upper structure (300) including a lower slab reinforcement plate through which the anchor penetrates while being supported on the concrete wall of the lower structure, a composite reinforcing bar arranged on an upper portion of the lower slab reinforcement plate, and a bottom slab constructed on the lower slab reinforcement plate. The anchor includes: an anchor body (131) having a multiple steel pipe shape; and an anchor bar fixed to the anchor body and supporting the upper structure. The anchor body includes: an outer pipe; a cover plate formed in the form of a wing on the circumference of the outer pipe; at least one inner pipe inserted into the outer pipe in the form of a concentric circle; a lower blocking plate coupled to the bottom of the outer pipe; and an upper blocking cap coupled to an upper portion of the inner pipe or the outer pipe.;COPYRIGHT KIPO 2020
