METHOD FOR REPLACING SEISMIC ISOLATOR
PROBLEM TO BE SOLVED: To provide a method for replacing a seismic isolator, which enables a seismic isolator to be replaced by jacking up a protrusion of a building frame even if a space for installing a jack device cannot be secured below the protrusion.SOLUTION: When an existing seismic isolator 10x which is disposed between a protrusion 6 and a supporting part 2 located below the protrusion 6 is replaced with a new seismic isolator, the protrusion 6 being located below a column 4a of a building frame 4 of a building and protruding downward, a plurality of through-holes 22 are horizontally formed in the protrusion 6, and a shaft member 23 is inserted in each of the plurality of through-holes 22 in such a way that both ends of the shaft member 23 protrude from a side face of the protrusion 6. A bracket 24 is coupled to the end of the shaft member 23. The existing seismic isolator 10x is replaced with the new seismic isolator by installing a jack device 20 below the bracket 24 and jacking up the protrusion 6.SELECTED DRAWING: Figure 3
【課題】躯体の突出部の下方にジャッキ装置を設置するスペースが確保できない場合であっても、突出部をジャッキアップして免震装置の交換を可能とする免震装置の交換方法を提供する。【解決手段】建築物の躯体４のうち柱４ａの下方に位置するとともに下方に向かって突出する突出部６と、この突出部６の下方に位置する支持部２と、の間に設けられた既存免震装置１０ｘを新規免震装置に交換するに際し、突出部６に対して水平方向に複数の貫通孔２２を形成し、複数の貫通孔２２のそれぞれに、軸材２３を、その両端部が突出部６の側面から突出するようにして挿入し、軸材２３の端部に、ブラケット２４を連結し、ブラケット２４の下方にジャッキ装置２０を設置して突出部６をジャッキアップしてから、既存免震装置１０ｘを新規免震装置に交換する。【選択図】図３
