CONTINUOUS GIRDER BRIDGE AND CONSTRUCTION METHOD THEREOF

PROBLEM TO BE SOLVED: To provide a continuous girder bridge having an intermediate fulcrum, excellent in workability with a simple structure, and a construction method thereof.SOLUTION: One continuous girder 20 is constituted via a discontinuous panel point part 30 formed of both end parts, by installing both bearing plates 2 and 2 in both end parts, by oppositely placing the end parts 1a and 1a of two steel girders 1 and 1 extending on the same bridge axis directional line with a clearance G on an upper surface 10a of a bridge pier 10 without being fixed, and a connection structure 100 is constituted by integrating the respective panel point parts 30 by a concrete member 40 formed on its periphery including the clearance G on an upper surface of the bridge pier 10, by forming the panel point part 30 for constituting two or more of continuous girders 20 at an interval in its bridge axis right-angled direction on the upper surface of one bridge pier 10, and a continuous bridge girder 1000 is constituted of at least the bridge pier 10 arranged at an interval in the bridge axis direction and a plurality of continuous girders 20 formed by connecting a plurality of steel girders via the connection structure 100 on the bridge pier 10.
