SEISMIC ISOLATION JACK DEVICE AND SEISMIC ISOLATION DEVICE REPLACEMENT METHOD
PROBLEM TO BE SOLVED: To provide a seismic isolation device replacement method, which enables work to be conducted without imposing horizontal force on a seismic isolation support part, and seismic isolation device replacement work to be conducted so that a seismic isolation performance of a building is maintained.SOLUTION: A seismic isolation device replacement method comprises following processes: to dispose a seismic isolation support jack device 3 around an existing seismic isolation device 2 and fix a lower linear slider 5 on a foundation slab 11; to extend a support jack 6 to make an upper linear slider 4 butt to a lower flange 10A of a beam material 10 and bear a load of an upper structure; to fix the upper linear slider 4 to the lower flange 10A of the beam material 10 using a friction joint jig; to remove the existing seismic isolation device 2 from between the beam material 10 and the foundation slab 11; to fix another seismic isolation device 2 to a fitting part between the beam material 10 and the foundation slab 11; and to remove the seismic isolation support jack device 3 from between the beam material 10 and the foundation slab 11.SELECTED DRAWING: Figure 1
【課題】免震支承部分で水平力を負担させることなく作業を行うことができ、建物の免震性能を維持した状態で免震装置の交換作業を行うことができる。【解決手段】既設の免震装置２の周囲に免震支持ジャッキ装置３を配置し、下部リニアスライダ５を基礎スラブ１１に固定する工程と、支持ジャッキ６を伸張させて上部リニアスライダ４を梁材１０の下フランジ１０Ａに当接させ、上部構造の荷重を負担する工程と、梁材１０の下フランジ１０Ａに上部リニアスライダ４を摩擦接合治具を用いて固定する工程と、既設の免震装置２を梁材１０と基礎スラブ１１の間から取り外す工程と、別の免震装置２を梁材１０と基礎スラブ１１の間の取付部分に固定する工程と、免震支持ジャッキ装置３を梁材１０と基礎スラブ１１の間から取り外す工程と、を有する免震装置の交換方法を提供する。【選択図】図１
