LAMINATED RUBBER BEARING INCLUDING LEAD PLUG
To propose a laminated rubber bearing including a lead plug which can maintain stable damping performance even if a large shear force acts thereon and does not cause harmful effect on a peripheral environment.SOLUTION: A laminated rubber bearing 1 includes: laminated rubber 2 formed by laminating multiple rubber plates 21 and multiple metal plates 22 alternately; a lead plug 3 embedded in the laminated rubber 2; an upper steel plate 41 which covers an upper surface of the laminated rubber 2; and a lower steel plate 42 which covers a lower surface of the laminated rubber 2. A thickness of the rubber plates 21, disposed at an upper part and a lower part of the laminated rubber 2, of the rubber plates 21 is smaller than a thickness of the rubber plates 21 disposed at a center part of the laminated rubber 2 as seen in a lamination direction.SELECTED DRAWING: Figure 2
【課題】大きなせん断力が作用した場合であっても、安定した減衰性能を維持することができ、また、周辺環境へ悪影響を及ぼすことがない鉛プラグ入り積層ゴム支承を提案する。【解決手段】複数のゴム板２１と複数の金属板２２とが交互に積層されてなる積層ゴム２と、積層ゴム２に埋め込まれた鉛プラグ３と、積層ゴム２の上面を覆う上鋼板４１と、積層ゴム２の下面を覆う下鋼板４２とを備える積層ゴム支承１である。複数のゴム板２１のうち、積層ゴム２の上部および下部に配設されたゴム板２１の厚さが、積層ゴム２の積層方向中央部に配設されたゴム板２１の厚さよりも小さい。【選択図】図２
