Title:
SEISMIC ISOLATION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2015/025820
Kind Code:
A1
Abstract:
The present invention has: a seismic isolation pillar (10) that is disposed between two pillar members (1A, 1B) of which the flat end surfaces (6, 7) face each other, and that can tilt from the state of forming flat contact surfaces (8, 9) at one end and the other end thereof to which the flat end surfaces (6, 7) are pressure-joined, and the contact surfaces (8, 9) being pressure-joined to the flat end surfaces (6, 7); and a stopper member (13) that is provided to at least one of the seismic isolation pillar (10) and the two pillar members (1A, 1B), prevents the movement of the seismic isolation pillar (10) in the horizontal direction when the two pillar members (1A, 1B) move relative to each other in the horizontal direction, and is such that a fulcrum (E) is formed at which the tilting of the seismic isolation pillar (10) starts from the state of the end surfaces (6, 7) and contact surfaces (8, 9) being pressure-joined. A trigger mechanism (11) is configured from the stopper member (13) forming the fulcrum (E), the flat end surfaces (6, 7) of the two pillar members (1A, 1B), and the flat contact surfaces (8, 9) of the seismic isolation pillar (10) to which the end surfaces (6, 7) are pressure-joined.
