SEISMIC ISOLATION DEVICE AND SEISMIC ISOLATION METHOD
PROBLEM TO BE SOLVED: To realize a seismic isolation device which has a simple structure, can be easily installed and is inexpensive and a seismic isolation method using the same.SOLUTION: In a construction support structure with a column 6 of a superstructure 3 inserted into a concave section 5 constructed on a foundation, a seismic isolation device is installed in the concave section. The seismic isolation device has a simple structure provided with: a bottom plate 7 arranged on a bottom face of the column; and an elastic body 8 which is arranged between the concave section and the column and the bottom plate. The elastic body has: an axial direction section 8a including a section arranged between a lower face of the bottom plate and the bottom face of the concave section; a lateral section 8b including the section arranged between a side face of the column and an inner side face of the concave section. When hit by an earthquake, the seismic isolation device absorbs horizontal oscillation with the elastic body while allowing the bottom face of the column and an upper face of the bottom plate to slide each other.SELECTED DRAWING: Figure 1
【課題】構造が簡素で設置が容易、かつ安価な免震装置及びそれを用いた免震工法を実現する。【解決手段】基礎に凹部５を形成し、凹部に上部構造物３の支柱６を挿入してなる構造物の支持構造において、凹部に免震装置が設けられる。その免震装置は、支柱の底面に配置される底板７と、凹部と支柱及び底板との間に配置される弾性体８とを備える簡素な構造である。弾性体は、底板の下面と凹部の底面との間に配置される部分を含む軸方向部８ａと、支柱の側面と凹部の内側面との間に配置される部分を含む側方部８ｂとを有する。地震時には支柱の底面と底板の上面とを滑動させつつ弾性体で水平振動を吸収する。【選択図】図１
