SLIDING BASE ISOLATION BEARING STRUCTURE DURING CONSTRUCTION, AND CONSTRUCTION METHOD FOR BASE ISOLATION BUILDING

摘要

To provide a sliding base isolation bearing structure during construction and a construction method of a base isolation building capable of reducing construction labor and easily erecting a steel beam between steel columns even by tolerance accumulation.SOLUTION: In a sliding base isolation bearing structure 100 at the time of construction constituted by a lower structure 20 and an upper structure 30 of a building, a sliding base isolating device 10 interposed therebetween, and fixing jigs 50, 50A, the sliding base isolation device 10 includes: an upper shoe 1 and a lower shoe 2 having sliding surfaces having curvatures; and a steel slider 3 arranged between the upper shoe 1 and the lower shoe 2 and having upper and lower surfaces having curvatures. The lower shoe 2 is mounted on the lower structure 20 without being fixed by bolts while the upper structure 30 is mounted on the upper shoe 1 without being fixed by bolts, and the upper shoe 1 and the lower shoe 2 are temporarily fixed in a state in which relative movement is regulated by a plurality of fixing jigs 50, 50A.SELECTED DRAWING: Figure 1
