BASE ISOLATION DEVICE, SLIDING BEARING, AND BASE ISOLATION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a base isolation device superior in inexpensiveness, durability, and base isolation performance to a laminated rubber base isolation device. SOLUTION: The base isolation device comprises a base-isolation and sliding bearing composed of a slip surface part, a restoration device constituted by gravitational restoration, a spring, etc., a pull-out preventing device for preventing pull-out force caused by seismic force, a wind, etc., and a fixed pin device for preventing swaying caused by the wind.
