Title:
BASE-ISOLATION RUBBER BEARING STRUCTURE
Document Type and Number:
Japanese Patent JP3819752
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a base-isolation rubber bearing structure, in which several kinds of initial stiffness can be set by one base-isolation rubber bearing structure and which has excellent mass productivity.
SOLUTION: In the base-isolation rubber bearing structure 10 with a laminated member 11 in which a plurality of hard boards having stiffness and a plurality of soft boards having viscoelasticity are laminated alternately, an inserting hole 30 in which a stiff body 32 can be fitted is formed extending over a lower section from an upper section at a central section, and the stiff body 32 can be inserted into the inserting hole 30. The quantity of the laminated member 11 deformed is controlled by changing the length of the stiff body 32.
