ASEISMIC BASE ISOLATION DAMPER
To provide an aseismic base isolation damper which can present low damping power for shake of an earthquake in medium/small amplitude scale and present high damping power for shape of an earthquake in large amplitude scale and further, is lightweight, simplified in a structure and inexpensive.SOLUTION: An aseismic base isolation damper D comprises: a cylinder 1; a piston 2 which is inserted into the cylinder 1 in a freely slidable manner and separates an extension-side chamber E and a compression-side chamber C; a rod 3 which is inserted into the cylinder 1 and connected to the piston 2; a reservoir R; an extension-side partition wall member 4 which partitions the extension-side chamber E into an extension-side working chamber EW and an extension-side sub reservoir chamber ER communicating to the reservoir R; and a compression-side partition wall member 5 which partitions the compression-side chamber C into a compression side working chamber CW and a compression-side sub reservoir chamber CR communicating to the reservoir R. When the extension-side partition wall member 4 is displaced to an extension-side regulation position, the displacement is regulated and when the compression-side partition wall member 5 is displaced to a compression-side regulation position, the displacement is regulated.SELECTED DRAWING: Figure 2
【課題】中小振幅の規模の地震の揺れに対して低い減衰力を発揮し、大振幅の地震の揺れに対して高い減衰力を発揮できるだけでなく、軽量かつ構造が簡単で安価な免震用ダンパの提供である。【解決手段】本発明の免震用ダンパＤは、シリンダ１と、シリンダ１内に摺動自在に挿入されて伸側室Ｅと圧側室Ｃを仕切るピストン２と、シリンダ１に挿入されるとともにピストン２に連結されるロッド３と、リザーバＲと、伸側室Ｅを伸側作動室ＥＷとリザーバＲに連通される伸側副リザーバ室ＥＲとに区画する伸側隔壁部材４と、圧側室Ｃを圧側作動室ＣＷとリザーバＲに連通される圧側副リザーバ室ＣＲとに区画する圧側隔壁部材５とを備え、伸側隔壁部材４が伸側規制位置まで変位するとの変位が規制され、圧側隔壁部材５が圧側規制位置まで変位すると変位が規制される。【選択図】図２
