BRIDGE FALLING PREVENTION STRUCTURE
PROBLEM TO BE SOLVED: To provide a bridge falling prevention structure capable of suppressing as much as possible functional reduction in a bridge due to earthquake disaster with a simple construction.SOLUTION: There is provided a bridge falling prevention structure in which a bridge pier 11 and a bridge girder 12 of a bridge 1 are connected. In addition, it comprises a lower bracket 2 fixed onto a bridge axis surface 11a of the pier, an upper bracket 3 fixed onto a bridge axis inner surface 12a of the girder, a PC cable 4 connecting the lower bracket and the upper bracket, and shearing blocks 5 and 5 arranged on both sides in a bridge axis orthogonal direction X of the bridge girder in an upper surface 11b of the pier.SELECTED DRAWING: Figure 1
【課題】簡単な構成で震災による橋梁の機能低下を最小限に抑えることが可能な落橋防止構造を提供する。【解決手段】橋梁１の橋脚１１と橋桁１２とを接続させる落橋防止構造である。そして、橋脚の橋軸面１１ａに固定される下部ブラケット２と、橋桁の橋軸内面１２ａに固定される上部ブラケット３と、下部ブラケットと上部ブラケットとを連結させるＰＣケーブル４と、橋脚の上面１１ｂにおいて橋桁の橋軸直交方向Ｘの両側に設置されたせん断ブロック５，５とを備えている。【選択図】図１
