CONTINUOUS GIRDER BRIDGE AND METHOD FOR CONSTRUCTION OF THE SAME

摘要

Provided are a continuous girder bridge including an intermediate support having a simple structure while being excellent in workability and a method for construction of the same. A continuous girder bridge 1000 at least includes: two steel girders 1, 1 extending on a line in a bridge axial direction at a top face lOa of a pier 10, the two steel girders 1,1 having ends la, la opposed without being fixed mutually while having gap G therebetween, a bearing plate 2 being attached to each of the ends, the two steel girders defining one continuous girder 20 via a discontinuous panel point part 30 defined by the ends, the panel point part 30 being defined including two or more of the continuous girders 20 being disposed at intervals in the bridge axial-orthogonal direction on a top face of one pier 10, a concrete member 40 to be placed around each panel point part 30 including its gap G for integration at the top face of the pier 10, thus making up a connecting structure 100, and the piers 10 placed at intervals in the bridge axial direction, and a plurality of continuous girders 20 including a plurality of steel girders coupled on the piers 10 via the connecting structure 100.
