SEISMIC BASE ISOLATION SUPPORT APPARATUS
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.
