PURPOSE:To provide a laminated rubber support wherein long period use can be attained o provide large horizontal deformation ability and further to prevent generation of buckling in a laminated rubber. CONSTITUTION:A rubber-made bag unit 2 is mounted to the inside of a laminated rubber 1 formed in a ring shape. Upper/lower part plates 4, 5 for installation are provided respectively above and below the laminated rubber 1 and the bag unit 2. Fluid of compressed air or the like is injected from a filler port 3 into the bag unit 2 to inflate it in a vertical direction. Compressed air in the bag unit 2 bears a burden fully or partly of a perpendicular load, acting on a laminated rubber support A, to prevent buckling of the ring-shaped laminated rubber 1. The laminated rubber support for long period use can be attained with small horizontal rigidity of the ring-shaped laminated rubber 1. |
