REINFORCEMENT STRUCTURE OF BRIDGE
PROBLEM TO BE SOLVED: To propose a reinforcement structure of a bridge, easy in construction, excellent in work efficiency, and capable of surely reinforcing an existing bridge.SOLUTION: A structure is provided for reinforcing a bridge 1 constituted in such a way that a bridge girder 3 is built across support parts composed of a bridge abutment and/or a bridge pier 2, and the reinforcement structure of the bridge comprises: a polystyrene resin foam block 4 stacked up to the vicinity of the undersurface of the bridge girder 3 in a space between the support parts; and a heat barrier 5 on an upper surface of the stacked polystyrene resin foam block 4, and the reinforcement structure of the bridge is constituted by injecting a foamable polyurethane resin into a clearance between the heat barrier 5 and the bridge girder 3, and foaming the foamable polyurethane thereby filling the clearance with the foam polyurethane resin 6.SELECTED DRAWING: Figure 6
【課題】施工が容易で作業性に優れると共に、既設橋梁を確実に補強することができる橋梁の補強構造体を提案すること。【解決手段】橋台及び／又は橋脚２からなる支持部の間に橋桁３を架け渡した構成の橋梁１を補強する構造体であって、上記支持部の間の空間に、橋桁３の下面近傍まで積み重ねられたポリスチレン系樹脂発泡体ブロック４と、該積み重ねたポリスチレン系樹脂発泡体ブロック４の上表面に遮熱層５とを有し、該遮熱層５と上記橋桁３との間のすき間に、発泡性ポリウレタン樹脂を注入、発泡させて発泡ポリウレタン樹脂６を充填してなる橋梁の補強構造体とした。【選択図】図６
