REPLACEMENT METHOD OF BASE-ISOLATION DEVICE IN PILE HEAD BASE-ISOLATION STRUCTURE
PROBLEM TO BE SOLVED: To replace an existing base-isolation device with a new base-isolation device, in a pile head base-isolation structure for providing a horizontal connection member between pile head parts unreplaceable with a conventional base-isolation device.SOLUTION: A reaction receiving member having a required thickness and a required size of a quadrangular shape on the periphery, is integrally constructed with a foundation pile around a pile head part of the foundation pile in a state of holding earthquake resistant performance of the foundation pile 1, and a support member 20 constituted of at least a skid material 21 and a jack and having the base-isolation function, is installed in a plurality of places in a position corresponding to the reaction receiving member, and while holding the earthquake resistant performance of the foundation pile together with a base-isolation state of an upper structure, an existing base-isolation device 7 is replaced with a new base-isolation device by supporting a load of the upper structure by the support member. Thus, even a base-isolation device installed in a conventionally nonexecutable foundation pile head part can be easily replaced.SELECTED DRAWING: Figure 1
【課題】従来の免震装置が交換不能な杭頭部間に水平つなぎ部材を設けた杭頭免震構造において、既設免震装置を新たな免震装置と交換できるようにすること。【解決手段】基礎杭１の耐震性能を保持した状態で、該基礎杭の杭頭部の周りに周囲が四角形状の所要厚みで所要大きさの反力受け部材を該基礎杭と一体的に構築し、該記反力受け部材に対応する位置で、少なくとも滑り材２１とジャッキとで構成された免震機能を有する支持部材２０を複数箇所に設置し、上部構造体の免震状態と共に該基礎杭の耐震性能を保持したままで、該支持部材で該上部構造体の荷重を支持させて既設免震装置７を新たな免震装置と交換する。これにより、従来できなかった基礎杭頭部に設置された免震装置でも、簡単に取り換えることができる。【選択図】図１
