<P>PROBLEM TO BE SOLVED: To provide a base isolation support which reduces the influence of seismic force to a building and is easily assembled. <P>SOLUTION: The base isolation support 1 is formed from upper receiving seats 2 fixed to a lower end of a building body, lower receiving seats 3 fixed to an upper end of a foundation arranged on the ground, and support bodies 1 oscillatably coupled between the upper receiving seat 3 and the lower receiving seat respectively. The support bodies have circular column parts 11 and coupling parts formed at the upper ends and the lower ends of the circular column parts 11. The upper receiving seats 2 and the lower receiving seats 3 are formed of distal end housing parts 21, 31 in which housing chambers 23, 33 housing the coupling parts of the support bodies 1 are formed and opening side fixing parts 22, 32 fixed to opening sides of the distal end housing parts 21, 31. The housing chambers 23, 33 of the distal end housing parts 21, 31 are formed in diameter enlarging wall surfaces 25, 35 whose diameter is enlarged such that the opening sides form the maximum diameter more than centers in a depth direction in the wall surface of the outer peripheral side and has convex parts 26, 36 protruding to the inside of the diameter enlarging wall surfaces 25, 35 from bottoms. The opening side fixing parts 22, 32 are constituted by combining two arcuate parts 22a, 22b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
