BEARING STRUCTURE OF BRIDGE
PROBLEM TO BE SOLVED: To provide a bearing structure of a bridge of a simple configuration that minimizes decline in a bridge function due to an earthquake disaster.SOLUTION: A bearing structure of a bridge is interposed between a bridge abutment 11 and a bridge girder 12 of a bridge 1, and includes a pedestal part 3 fixed on a top surface 111 side of the bridge abutment, and a rubber bearing 2 installed on the pedestal part. A peripheral protrusion 32 is provided to surround a top edge of the pedestal part, and the rubber bearing is housed in a recess 34 surrounded by the protrusion. A drain pipe 4 is provided on the pedestal part, to link the recess to outside.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橋梁の支承構造を提供する。【解決手段】橋梁１の橋台１１と橋桁１２との間に介在させる橋梁の支承構造である。そして、橋台の上面１１１側に固定された台座部３と、台座部に設置されたゴム支承２とを備えている。さらに、台座部には上縁を囲繞する周状の突起部３２が設けられており、突起部に囲まれた凹部３４にゴム支承が収容されている。また、台座部には、凹部と外部とを連通させる排水経路となる排水管４が設けられている。【選択図】図１
