TEMPORARY STRUCTURE FOR BRIDGE GIRDER REMOVAL AND BRIDGE GIRDER REMOVING DEVICE
To provide a temporary structure for bridge girder removal, a construction method thereof, and a bridge girder removal device, which can prevent damage to the substructure and collapse of the temporary structure caused by earthquake loads acting on the temporary structure for bridge girder removal when a major earthquake occurs during construction.SOLUTION: A temporary structure 100 for bridge girder removal, which is applied to bridge girder removal construction, in which existing bridge girders G erected on existing bridge piers P are dismantled and transported has multiple temporary supporting bodies 60 installed at intervals above the bridge girder G, and temporary girders 10 that are erected on the multiple temporary supporting bodies 60 and extend in the bridge axis direction. The temporary supporting bodies 60 are equipped with seismic isolation bearings 80 that reduce the inertial force during an earthquake during bridge girder removal construction.SELECTED DRAWING: Figure 9
【課題】工事期間中に大地震が発生した際に、橋桁撤去用の仮設構造体に作用する地震荷重に起因する下部工の破損や仮設構造体の落下等を防止できる、橋桁撤去用の仮設構造体とその施工方法、及び橋桁撤去装置を提供する。【解決手段】既設の橋脚Ｐの上に架設されている既設の橋桁Ｇを解体して搬送する、橋桁撤去施工に適用される、橋桁撤去用の仮設構造体１００であり、橋桁Ｇの上方に間隔を置いて設置されている、複数の仮設支持体６０と、複数の仮設支持体６０に架設され、橋軸方向に延設している、仮設桁１０とを有し、仮設支持体６０は、橋桁撤去施工の際の地震時の慣性力を低減する免震支承８０を備えている。【選択図】図９
