LAMINATE RUBBER BEARING DEVICE
PROBLEM TO BE SOLVED: To provide a laminate rubber bearing device capable of not only preventing the reduction of a vibration energy absorption by a columnar metal body such as a lead core or a lead plug but also acquiring high rigidity and a load support capacity in a laminate layer direction.SOLUTION: A laminate rubber bearing device 1 comprises: a cylindrical laminate 4 made by laminating disc-shaped steel plates 2 and a disc-shaped rubber layers 3; a disc-shaped intermediate steel plate 5 arranged in the rubber layer 3 between the steel plates 2; and a columnar lead plug 7 arranged in a columnar hollow part 6 extending the individual central parts of the steel plates 2, the rubber layer 3 and the intermediate steel plate 5.
【課題】鉛コア又は鉛プラグ等の円柱状金属体による振動エネルギ吸収能の低下を防ぐことができる上に、積層方向における高い剛性と荷重支持能力とを得ることができる積層ゴム支承装置を提供すること。【解決手段】積層ゴム支承装置１は、円盤状の鋼板２と円盤状のゴム層３とを交互に積層してなる円筒状の積層体４と、鋼板２間においてゴム層３内に配された円盤状の中間鋼板５と、鋼板２、ゴム層３及び中間鋼板５の夫々の中央部を積層方向Ｖにおいて貫通した円柱状中空部６に配されている円柱状の鉛プラグ７とを具備している。【選択図】図１
