INSTALLATION METHOD FOR SEISMIC ISOLATOR
PROBLEM TO BE SOLVED: To provide an installation method for two or more seismic isolators of different types, without generating a harmful deformation between a superstructure and a substructure that could damage the superstructure.SOLUTION: An installation method for a seismic isolator includes the following steps for: disconnecting an existing structure into a superstructure and a substructure, while supporting the superstructure with a plurality of support members; installing two or more seismic isolators on the substructure; forming a gap between one or more seismic isolators and the substructure, in accordance with a vertical displacement amount assumed for each of the seismic isolators when a load of the superstructure is exerted on each of the seismic isolators; and shifting the load of the superstructure exerted on the plurality of support members to the two or more seismic isolators, and removing the plurality of support members.SELECTED DRAWING: Figure 2
【課題】 種類が異なる２以上の免震装置を、上部構造と下部構造との間に該上部構造が損傷し得る有害な変形を発生させないように設置する方法を提供する。【解決手段】 この方法は、既存の構造物の上部構造を複数の支持部材により支持しつつ上部構造と下部構造とに切断する工程と、下部構造上に２以上の免震装置の各々を設置する工程と、上部構造の荷重を各免震装置に加えた場合に推定される各免震装置の鉛直変位量に応じて、１以上の免震装置と上部構造との間に隙間を形成する工程と、複数の支持部材にかかる上部構造の荷重を２以上の免震装置へ移行させ、複数の支持部材を撤去する工程とを含む。【選択図】 図２
