Title:
LAMINATION RUBBER SUPPORT
Document Type and Number:
Japanese Patent JP2016223586
Kind Code:
A
Abstract:
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
