SLIDE PIVOT TYPE SEISMIC ISOLATION STRUCTURE
To provide a slide pivot type seismic isolation structure which uses linear steel frame members normally available in a market, is suppressed in a possibility for imparting adverse effects to material characteristics of the steel frame members, can inexpensively manufacture a fall prevention member, and can simply and easily perform the exchange work of a slide plate.SOLUTION: In a slide pivot type seismic isolation structure, a slide plate 4 is arranged at an upper face of a base plate 3 arranged at an upper face of a lower structure, a slide structure 5 arranged at a lower face of an upper structure is constituted so as to be slidable on the slide plate 4, and a fall prevention member 9 for preventing a fall of the slide structure 5 is arranged at an external periphery of the base plate 3. The fall prevention member 9 is constituted while arranging linear steel frame members 9a in a rectangular shape in a plane view, and the linear steel frame members 9a are individually attached to the lower structure by a fall prevention member fastening tool 10 by a fastening operation from above.SELECTED DRAWING: Figure 2
【課題】通常市販されている直線状の鉄骨部材を使用し、その鉄骨部材の材料特性に悪影響を与える可能性が少なく、脱落防止部材を廉価に作製することができ、かつ、滑り板の取り換え作業も簡単かつ容易に行うことができる滑り支承型の免震構造の提供。【解決手段】下部構造体の上面に設けられたベースプレート３の上面に滑り板４が配設され、上部構造体の下面に配設の滑り構造体５が、滑り板４上で摺動可能に構成され、滑り構造体５が脱落するのを防止する脱落防止部材９が、ベースプレート３の外周に配設される滑り支承型の免震構造で、脱落防止部材９が、平面視において直線状の鉄骨部材９ａを矩形に配置して構成され、直線状の鉄骨部材９ａのそれぞれが、上方からの締付け操作により脱落防止部材用締付け具１０によって下部構造体に各別に取付けられる。【選択図】図２
