FIXING STRUCTURE OF SEISMIC ISOLATOR
To provide a fixing structure of a seismic isolator which is easy in installation at construction, can follow large deformation at the occurrence of a huge earthquake, and can exert high seismic isolation performance even if a long-period/long-time earthquake motion occurs.SOLUTION: A fixing structure of a seismic isolator arranged between an upper structure and a lower structure, and pivoting the upper structure in terms of seismic isolation has a plane part arranged at the lower structure, and a slide plate which is arranged on the plane part, and in which a pivot main body fixed to the upper structure on a slide face of an upper face is slidably placed. A penetration hole penetrating in a vertical direction is formed at an outer edge part of the slide plate, a protruding member protruding upward from the plane part, and arranged in the penetration hole of the slide plate is arranged at the plane part, the protruding member is fixed to the plane part, a tip face of the protruding member is arranged in the penetration hole, and a horizontal clearance for permitting the horizontal movement of the slide plate with respect to the plane part is arranged between the protruding member and the penetration hole.SELECTED DRAWING: Figure 3
【課題】建設時の施工が容易であるとともに、大地震発生時の大変形に追従でき、かつ、長周期・長時間地震動が生じても、高い免震性能を実現すること。【解決手段】上部構造物と下部構造物の間に配置されて 上部構造物を免震支承する免震装置の固定構造であって、下部構造物に設けられる面状部と、面状部上に設置され、且つ、上面のすべり面で、上部構造物に固定されるすべり支承本体が摺動可能に載置されるすべり板と、を有し、すべり板の外縁部には、上下方向に貫通する貫通孔が設けられ、面状部には、面状部から上方に突出して、すべり板の貫通孔内に配置される突出部材が設けられ、突出部材は、面状部に固定され、突出部材の先端面は貫通孔内に配設され、突出部材と貫通孔の内周面との間には、面状部に対するすべり板の水平移動を許容する水平隙間が設けられている。【選択図】図３
