ASEISMIC BASE ISOLATION DAMPER
PROBLEM TO BE SOLVED: To provide an aseismic base isolation damper eliminating any maintenance work after occurrence of a large-scale earthquake, and not increasing any cost and not realizing any attenuation force against a small-scale earthquake, but capable of realizing attenuation force against a large-scale earthquake.SOLUTION: An aseismic base isolation damper D of this invention comprises a cylinder 1; a piston rod 2 having a first rod 3 and a second rod 4 movable in an axial direction against the first rod 3 and movably inserted into the cylinder 1; an extending side stopper 5 and a compression side stopper 6 arranged at the first rod 3 while being spaced apart in an axial direction; and a stopper opposing member 7 arranged at the second rod 4 for restricting motion of the first rod 3 toward a counter cylinder side against the second rod 4 upon abutment against the extending side stopper 5 in opposition to the extending side stopper 5 and the compression side stopper 6 and at same time for restricting motion of the first rod 3 toward the cylinder side against the second rod 4 upon abutment against the compression side stopper 6.SELECTED DRAWING: Figure 1
【課題】大規模地震発生後のメンテナンス作業が不要でコストの増大を招かずに、小規模地震に対しては減衰力を発揮せず大規模地震に対しては減衰力を発揮可能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、第一ロッド３と第一ロッド３に対して軸方向に移動可能な第二ロッド４とを有してシリンダ１内に移動可能に挿入されるピストンロッド２と、第一ロッド３に軸方向に離間して設けられる伸側ストッパ５と圧側ストッパ６と、第二ロッド４に設けられて伸側ストッパ５と圧側ストッパ６とに対向して伸側ストッパ５に当接すると第一ロッド３の第二ロッド４に対する反シリンダ側への移動を規制するとともに圧側ストッパ６に当接すると第一ロッド３の第二ロッド４に対するシリンダ側への移動を規制するストッパ対向部材７とを備えた。【選択図】図１
