BRIDGE CONSTRUCION METHOD USING PSC GIRDER UNIFIED WITH SLAB

摘要

PURPOSE: A bridge construction method using a PSC girder integrated with a slab is provided to enable cost-efficient construction of a bridge by not requiring a slab construction process. CONSTITUTION: A bridge construction method using a PSC girder integrated with a slab is as follows: A pier is installed between abutments, and PSC girders integrated with slabs are installed between the pier and the abutments. Outermost cross-shaped PSC girders(100b) are installed in both sides of a bridge. PSC girders(100a) integrated with main slabs are installed to support the integrated slabs to the upper flanges of the uppermost cross-shaped PSC girders. A center cross-shaped PSC girder(100c) is installed to support the slabs to the upper flanges of the PSC girders integrated with main slabs. The girders are integrated by placing leveling concrete(400) on the top surfaces of the girders. A pavement layer and bridge railings are installed on the top surface of the leveling concrete.
