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

摘要

PROBLEM TO BE SOLVED: To transmit load generated from a seismic isolation structure (a building) evenly to each of a plurality of seismic isolation supports when improving pressure-resistance capability of the seismic isolation support.;SOLUTION: A plurality of the seismic isolation supports is united and a plurality of sets of the seismic isolation supports united is arranged side by side. A joining point is provided in a central portion of each of the sets. A beam 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. The pin support potions 4a, 4b (spherical seats) and the seismic isolation structure are joined together, thereby improving the pressure-resistance capability of the seismic isolation support.;COPYRIGHT: (C)2008,JPO&INPIT
