Title:
SEISMIC ISOLATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/054302
Kind Code:
A1
Abstract:
Provided is a seismic isolation device capable of ensuring good seismic isolation performance even under low temperature conditions and improving merchantability. The seismic isolation device 1 includes upper and lower spherical plates 10, 10 and a sliding body 20. The sliding body 20 has: a base portion 21; and upper and lower sliding members 22, 22 provided at upper and lower end portions thereof. A number of holes h0-h6 filled with a solid lubricant 23 are formed in a sliding surface 22a of each of the sliding members 22. The present invention is configured such that, by arranging the holes h1-h6 in a nonlinear manner in an orientation along a straight line H, the width (S3-S2) between the maximum value and the minimum value of a curve representing a variation mode of a cumulative value SumL of the distance passing through the holes h0-h6 for each orientation with the center hole h0 as a reference becomes smaller than that in the case where the holes h1-h6 are linearly arranged in this orientation.
