SEISMIC BEARING FOR BRIDGE AND BRIDGE USING THE SAME
PROBLEM TO BE SOLVED: To provide a seismic bearing for a bridge which can efficiently attenuate the vibration of the bridge in a bridge axial direction even though small.SOLUTION: A seismic bearing 1 for a bridge has a rubber plate 2, a steel plate 3, a laminated body 7, a hollow part 8 which is sealed and arranged in the laminated body 7, and a lead plug 9 which is tightly charged into the hollow part 8. The lead plug 9 has a pair of rectangular faces 71 in a bridge axial orthogonal direction which oppose each other in a bridge axial direction B, and a pair of rectangular faces 72 in the bridge axial direction B which oppose each other in the bridge axial orthogonal direction.SELECTED DRAWING: Figure 1
【課題】小型であっても、橋桁の橋軸方向の振動を効率よく減衰させることができる橋梁用の免震支承を提供する。【解決手段】橋梁用の免震支承１は、ゴム板２及び鋼板３に加えて、積層体７と、積層体７の内部に密閉されて設けられている中空部８と、中空部８に密に充填されている鉛プラグ９とを有しており、鉛プラグ９は、橋軸方向Ｂにおいて互いに対面する一対の橋軸直角方向の長方形の面７１と、当該橋軸直角方向において互いに対面する一対の橋軸方向Ｂの長方形の面７２とを有している。【選択図】図１
