BRIDGE-STEP PREVENTION MEMBER, AND BRIDGE-STEP SUPPRESSION STRUCTURE
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 suppression structure.SOLUTION: A bridge-step suppression structure 100 includes: a pier; a bridge bearing provided to the pier; a bridge superstructure 121 placed on the pier via the bridge bearing; and a bridge-step prevention member attached to the bridge superstructure 121, which is placed with a gap between the pier and itself. The bridge-step prevention member includes: multiple round steel pipes 142; and a support member holding box 145 that holds arrangement of the multiple round steel pipes 142 by enclosing the periphery of the multiple round steel pipes 142.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、及び橋梁段差抑制構造を提供すること。【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と、を備えた橋梁段差抑制構造１００であって、前記橋梁段差抑制部材は、複数の丸鋼管１４２と、複数の前記丸鋼管１４２の周囲を囲んでこれら複数の丸鋼管１４２の配列を保持する支持部材保持ボックス１４５を備えていることを特徴とする。【選択図】図５
