SEISMIC ISOLATOR INSTALLATION METHOD
PROBLEM TO BE SOLVED: To provide a seismic isolator installation method capable of suppressing change of positional relationship between an upper part and a lower part of a columnar body.SOLUTION: A seismic isolator installation method includes: a restraint step to fix a restraint device to an upper part and a lower part of a columnar body, which are located above and below an installation position where a seismic isolator is installed, respectively, in order to restrain the upper part and the lower part in a horizontal direction; a removal step to remove the section of the installation position of the columnar body; and an installation step to install the seismic isolator at the installation position of the columnar body. The restraint device comprises: an upper fixture, which is fixed to the upper part; a lower fixture, which is fixed to the lower part; and a jack disposed between the upper fixture and the lower fixture. In the removal step, the section of the installation position of the columnar body is removed after moving the load on an existing building from the columnar body to the jack by operating the jack.SELECTED DRAWING: Figure 1
【課題】 柱状体の上部と下部との位置関係が変化することを抑制することができる免震装置設置工法を提供する。【解決手段】 免震装置設置工法は、柱状体の免震装置を設置する設置位置の上部と下部とを水平方向で拘束するために、上部と下部とに拘束装置を固定する拘束工程と、柱状体の設置位置の部分を除去する除去工程と、免震装置を柱状体の設置位置に設置する設置工程と、を含み、拘束装置は、上部に固定される上固定具と、下部に固定される下固定具と、上固定具と下固定具との間に配置されるジャッキと、を備え、除去工程においては、ジャッキを操作することにより、既存建物の荷重を柱状体からジャッキに移した後で、柱状体の設置位置の部分を除去する。【選択図】 図１
