LAMINATION RUBBER SUPPORT
PROBLEM TO BE SOLVED: To provide a lamination rubber support that is preferable for assuring base isolation performance even if flexure deformation or shearing deformation occurs.SOLUTION: A lamination rubber support 16A is configured under an arrangement in which a plurality of steel plates 24 and a plurality of rubber plate segments 26 are alternatively laminated. A thickness of the steel plate 24 is set to such a size as one that is gradually decreased from a central part of a laminated rubber support 16 in its radial direction, toward an outer peripheral part. A thickness of rubber plate segments 26 is set to such a size in which an outer peripheral part is larger than that of a central part of a laminated rubber support 16A in its radial direction. More in detail, a thickness of rubber plate segments 26 is set to such a size in which it becomes gradually a larger size as it starts from an outer peripheral part toward a central part of the laminated rubber support 16A in its radial direction. Increasing a thickness of the rubber plate segments 26 at their outer peripheral portions in a radial direction of the laminated rubber support 16A, larger than the central part, enables a tensile strain of the rubber plate segments 26 to be decreased from their central part to the outer peripheral part.SELECTED DRAWING: Figure 1
【課題】曲げ変形やせん断変形が生じても免震性能を確保する上で有利な積層ゴム支承を提供する。【解決手段】積層ゴム支承１６Ａは、複数の鋼板２４と複数のゴム板部２６とが交互に積層されることで構成されている。鋼板２４の厚さは、積層ゴム支承１６の直径方向の中央部から外周部に至るにつれて次第に小さくなる寸法で形成されている。ゴム板部２６の厚さは、積層ゴム支承１６Ａの直径方向の中央部よりも外周部が大きい寸法で形成されている。より詳細には、ゴム板部２６の厚さは、中央部から外周部に至るにつれて次第に大きくなる寸法で形成されている。積層ゴム支承１６Ａの直径方向において、外周部のゴム板部２６の厚さを中央部より大きくすることで、外周部のゴム板部２６の引っ張りひずみを、中央部から外周部に至るまで小さくすることができる。【選択図】図１
