BASE ISOLATION REPAIR METHOD
PROBLEM TO BE SOLVED: To provide a base isolation repair method of installing a base isolation device on an existing skeleton while easily and precisely keeping constant a preloading state in which the base isolation device is loaded with predetermined certain axial force.SOLUTION: A base isolation device is installed on an existing pole. A method comprises: steps S1-S4 of removing a part of the existing pole and installing the base isolation device; a step S5 of installing a support member between the existing pole and base isolation device; steps S5-S7 of installing a plurality of hydraulic jacks on an upper surface of the base isolation device, and introducing axial force into the base isolation device by those hydraulic jacks; and steps S8, S9 of re-bearing the introduced axial force by the support member.SELECTED DRAWING: Figure 3
【課題】免震装置に所定の一定軸力を載荷されたプレロード状態を、容易にかつ精度良く一定に保持したまま、既存躯体に免震装置を設置する免震改修方法を提供する。【解決手段】既存柱に免震装置を設置する。既存柱の一部を撤去して免震装置を設置するステップＳ１〜Ｓ４と、既存柱と免震装置との間に支持部材を設置するステップＳ５と、免震装置の上面に油圧ジャッキを複数設置し、これら油圧ジャッキにより免震装置に軸力を導入するステップＳ５〜Ｓ７と、この導入した軸力を支持部材に受け替えるステップＳ８、Ｓ９と、を備える。【選択図】図３
