BASE ISOLATION BEARING STRUCTURE OF STRUCTURE, METHOD OF CONSTRUCTING BASE ISOLATION STRUCTURE, AND METHOD OF REPAIRING BASE ISOLATION STRUCTURE
To provide base isolation bearing structure of a base isolation structure, a construction method of a base isolation structure, and a repairing method of the base isolation structure capable of reducing an impact on the structure, preventing a rubber bearing from being broken, and being restored in an early stage even when a large external force is applied by an earthquake motion.SOLUTION: In base isolation bearing structure of a structure, a sliding bearing 11 is interposed between a laminated rubber bearing 10 and a structure 3, and the sliding bearing 11 includes a sliding projection 19 projecting via a load transmission member 18 fixed to an end of the laminated rubber bearing 10, a pedestal part 20 in which a sliding recessed part 21 is formed on a surface part and stopper members 22, 22,... for regulating the horizontal movement of the load transmission member 18. The stopper member 22 is released from fixation when a horizontal force equal to or greater than a prescribed external force acts on the load transmission member 18.SELECTED DRAWING: Figure 2
【課題】地震動により大きな外力が作用した場合であっても、構造物への衝撃が少なく、ゴム支承が破断せず、早期に復旧が可能な免震構造物の免震支承構造、免震構造物の構築方法及び免震構造物の改修方法の提供。【解決手段】構造物の免震支承構造は、積層ゴム支承１０と構造体３との間にすべり支承１１が介在され、すべり支承１１は、積層ゴム支承１０の端部に固定された荷重伝達部材１８を介して突設された滑動凸部１９と、表面部に滑動凹部２１が形成された台座部２０と、荷重伝達部材１８の水平方向移動を規制するストッパー部材２２，２２…とを備え、ストッパー部材２２が荷重伝達部材１８に所定の外力以上の水平力が作用すると固定解除されるようにしている。【選択図】図２
