BASE ISOLATION SUPPORT AND BASE ISOLATION STRUCTURE WHICH COMPRISE A PLURALITY OF BALLS (ROLLING ELEMENTS) AND SLIDING PORTION (SLIDER)

摘要

PROBLEM TO BE SOLVED: To improve pressure-resistance capability of a base isolation support by transmitting load generated from a base isolation structure (a building) evenly to each of a plurality of base isolation supports.;SOLUTION: A plurality of the base isolation supports is united and a plurality of sets of the base isolation supports united is arranged side by side. A joining point is provided in a central portion of each of the sets. A beam 3-d is provided with the joining point straddled thereby. Pin support portions 4a, 4b (spherical seats) are provided in a central portion between the contact points of the beam 3-d. The pin support potions 4a, 4b (spherical seats) and the base isolation structure are joined together, thereby improving the pressure-resistance capability of the base isolation support.;COPYRIGHT: (C)2009,JPO&INPIT
