- 下部構造物と上部構造物との間に配置され、前記下部構造物に対する上部構造物の水平方向変位を許容するアイソレータと、
前記下部構造物と上部構造物との間に設けられると共に、摺接面及び当該摺接面に対して前記上部構造物から作用する鉛直方向荷重によって押し付けられる摩擦部材を有し、前記上部構造物の水平方向変位に対して反力を及ぼすダンパーと、
地震動を検知するセンサーと、
前記センサーの出力に応じて動作し、前記下部構造物と前記上部構造物との間に加圧流体の圧力層を形成して前記摺接面に対する前記摩擦部材の押圧力を制御する軸力軽減装置と、を備え、
前記上部構造物には前記加圧流体の作用空間を当該上部構造物と下部構造物との間に区画する仕切り板が設けられる一方、前記下部構造物には前記上部構造物に生じる水平方向の変位量に応じて前記仕切り板が横切る流体排出溝が形成されていることを特徴とする免震システム。 - 前記上部構造物には所定の間隔を隔てて複数の仕切り板が多重に設けられ、前記上部構造物に生じる水平方向の変位量の増加に伴い、前記流体排出溝を横切る仕切り板が増加することを特徴とする請求項1記載の免震システム。
