US 2018/0030749 A1 · SEISMIC BASE ISOLATION SUPPORT APPARATUS

Abstract

A seismic base isolation support apparatus 1 includes: a laminated body 4 in which elastic layers 2 and rigid layers 3 are alternately laminated; a circularly columnar body 7 which is disposed in a hollow portion 6 of the laminated body 4; an outer peripheral protective layer 9 covering an outer peripheral surface 8 of the laminated body 4; an upper mounting plate 11 and a lower mounting plate 12 which are respectively connected to an uppermost rigid layer 3 of the rigid layers 3 and a lowermost rigid layer 3 of the rigid layers 3 by means of bolts 10; a shear key 15 which is fittingly secured in a recess 13 of the uppermost rigid layer 3 and a recess 14 of the upper mounting plate 11; and a shear key 18 which is fittingly secured in a recess 16 of the lowermost rigid layer 3 and a recess 17 of the lower mounting plate 12.

Dependent claims

A seismic base isolation support apparatus comprising:

a laminated body having a plurality of rigid layers and elastic layers which are alternately laminated;
and a columnar body having a columnar lead plug or tin plug and disposed in a columnar hollow portion defined by at least an inner peripheral surface of said laminated body, wherein said laminated body includes, in addition to the rigid layers and the elastic layers, an annular thermal conductor which is interposed between an outer peripheral surface of said columnar body and an annular inner surface of the elastic layer in such a manner as to be in contact with the outer peripheral surface of said columnar body, the annular inner surface of the elastic layer, and at least one surface of a pair of rigid layers sandwiching the elastic layer and having a thermal conductivity higher than that of the elastic layer.
