MAIN GIRDER FALL PREVENTION DEVICE
PROBLEM TO BE SOLVED: To provide a main girder fall prevention device, which supports main girders that face each other in bridge axial direction and are separated so as to be relatively displaceable to each other on an understructure, and is disposed across bearing bodies that face each other in bridge axial direction on the understructure and prevents either one of bearing bodies from falling around axis in bridge axial direction along with the main girder supported by the bearing body.SOLUTION: Multiple turning prevention materials 2, 2, which are disposed along bridge axial direction in parallel with width direction of a main girder 8 and directly or indirectly connected to a bearing body 7, are installed between bottom faces of facing bearing bodies 7,7 and a top face of an understructure 9. Both bearing bodies 7, 7 are linked on the bottom faces of the facing bearing bodies 7, 7.SELECTED DRAWING: Figure 1
【課題】橋軸方向に対向し、互いに相対変位自在に分離した主桁を下部構造上で支持し、下部構造上で橋軸方向に対向する支承体間に跨って設置され、いずれか一方の支承体が、それが支持する主桁と共に橋軸方向の軸回りに転倒することを防止する。【解決手段】対向する支承体7、7の底面と下部構造9の上面との間に、主桁8の幅方向に並列して橋軸方向に沿い、支承体7に直接、もしくは間接的に接続される複数本の回転防止材2、2を架設し、対向する支承体7、7の底面において両支承体7、7を連係させる。【選択図】図1
