Claims (3)
- 弾性材料層及び剛性材料層が交互に積層されていると共に積層方向と直交する剪断方向において弾性的に剪断変形自在な積層体と、この積層体の内周面で規定された柱状の中空部に配されていると共に剪断方向に変形自在であって加わる剪断方向の振動エネルギを当該剪断方向の変形により吸収する柱状の振動エネルギ吸収体とを具備しており、この振動エネルギ吸収体は、塑性金属材料からなる円柱状の中央部と、この中央部を積層方向において挟んで配されていると共に中央部の塑性金属材料の降伏点と異なる降伏点を有した塑性金属材料としての鉛からなる円柱状の上部及び下部とを具備しており、積層方向において同一の剪断方向の断面形状をもって積層方向に伸びており、中央部と上部及び下部との夫々は、凹凸嵌め合わせ又は合金化されて接合されている、前記積層方向の荷重を支持するようにした免震装置。
- 振動エネルギ吸収体は、積層方向において降伏点が積層方向の中央に関して対称となるように、積層方向において異なる塑性金属材料をもって形成されている請求項1に記載の免震装置。
- 振動エネルギ吸収体の円柱状の中央部は、錫又はその合金を含む塑性金属材料からなっている請求項1又は2に記載の免震装置。
