Title:
SEISMIC ISOLATION STRUCTURE OF PILLAR CONFIGURING STRUCTURE, AND STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2015/025821
Kind Code:
A1
Abstract:
The present invention is provided with: two pillar members (1A, 1B) disposed in a manner such that flat end surfaces (6, 7) oppose each other; a seismic isolation pillar (10) disposed between the two pillar members and having, at one end (10a) and another end (10b), flat contact surfaces (8, 9) opposing the flat end surfaces; a stopper member (13) that is disposed between the two pillar members and the seismic isolation pillar, prevents the one end and other end of the seismic isolation pillar from moving outwards in the horizontal direction with respect to the two pillar members when the two pillar members move relative to each other in the horizontal direction, and is such that the seismic isolation pillar tilts in a horizontal two-axis direction with respect to the two pillar members; and a trigger mechanism (11) that has an elastic body (19) adhering the contact surfaces of the seismic isolation pillar to the end surfaces of the two pillar members, and that starts tilting of the seismic isolation pillar centered on a fulcrum (E) by means of the stopper member (13). The elastic body (19) is disposed in a manner such that the trigger load differs by the horizontal two-axis direction when the tilting of the seismic isolation pillar (10) starts.
