BRIDGE-STEP PREVENTION MEMBER, BRIDGE-STEP PREVENTION STRUCTURE, AND BRIDGE GIRDER RESTORATION METHOD
To provide a bridge-step prevention member capable of preventing a bridge superstructure from falling off and creating a large step on the bridge even when a bridge bearing is broken, and a bridge-step prevention structure, and bridge girder restoration method.SOLUTION: A bridge-step prevention structure 100 includes: a pier; a bridge bearing placed on the pier; a bridge superstructure 121 that is placed on the pier via the bridge bearing; and a bridge-step prevention member 140 that is attached to the bridge superstructure 121 and placed with a gap between itself and the pier. The pier-step prevention member 140 includes an airbag 145 as a fluid holding member.SELECTED DRAWING: Figure 5
【課題】橋梁支承が損壊した場合であっても、橋梁上部工が脱落して、橋梁に大きな段差が生じるのを抑制することが可能な橋梁段差抑制部材、橋梁段差抑制構造、及び橋桁復旧方法を提供すること。【解決手段】橋脚と、前記橋脚に配置された橋梁支承と、前記橋梁支承を介して前記橋脚に配置された橋梁上部工１２１と、前記橋梁上部工１２１に取り付けられ、前記橋脚との間に間隙をあけて配置された橋梁段差抑制部材１４０と、を備えた橋梁段差抑制構造１００であって、前記橋脚段差抑制部材１４０は、流体保持部材としてエアバック１４５を備えていることを特徴とする。【選択図】図５
