PERIPHERAL CONSTRAINT TYPE EARTHQUAKEPROOF DEVICE

摘要

PURPOSE: To promote vertical loading capacity by setting a columnar rubbery body to the lower part of a structure and, at the same time, surrounding the circumference of the rubbery body to set a restraining body in a laminating state in the direction of the height. CONSTITUTION: A restraining body 12 formed by laminating a restraining plate 13 with high rigidity is set on the circumference of a columnar rubbery body 11 to form a base isolationg device A. Anchoring plates 14 fixed to upper and lower structures are respectively connected to both up and down surfaces of the base isolation device A.
