SEISMIC ISOLATOR AND ATTACHMENT STRUCTURE OF THE SAME
To provide a seismic isolator which achieves downsizing and has an anti-buckling function, and to provide an attachment structure of the seismic isolator.SOLUTION: A seismic isolator 10 includes: an elastic lamination body 12 in which inner elastic plates 14 of elastic bodies, and inner rigid plates 16 having rigidity higher than that of the inner elastic plate, are alternately laminated and integrally formed; an upper flange plate 28 fixed to an upper lamination body 24 and formed with upper attachment holes 34; a lower flange plate 30 fixed to a lower lamination body 26 and formed with lower attachment holes 38; upper cutout parts 32, each of which is formed by cutting out the upper lamination body 24, communicates with the upper attachment hole 34, and can house at least a part of a head 40A of a bolt 40 inserted into the upper attachment hole 34 in a plan view; and lower cutout parts 36, each of which is formed by cutting out the lower lamination body 26, communicates with the lower attachment hole 38, and can house at least a part of the head 40A of the bolt 40 inserted into the lower attachment hole 38.SELECTED DRAWING: Figure 1
【課題】小型化した上で耐座屈性能を備えた免震装置及びその取付構造を提供する。【解決手段】免震装置１０を、弾性体の内部弾性板１４と内部弾性板よりも剛性の高い内部剛性板１６が交互に積層されると共に一体に形成された弾性積層体１２と、上側積層体２４に固定され、上側取付孔３４が形成された上部フランジ板２８と、下側積層体２６に固定され、下側取付孔３８が形成された下部フランジ板３０と、上側積層体２４を切り欠いて形成され、上側取付孔３４と連通しかつ上側取付孔３４に挿入されるボルト４０の頭部４０Ａの少なくとも一部が平面視で収容可能とされた上側切欠部３２と、下側積層体２６を切り欠いて形成され、下側取付孔３８と連通しかつ下側取付孔３８に挿入されるボルト４０の頭部４０Ａの少なくとも一部が平面視で収容可能とされた下側切欠部３６と、を含んで構成する。【選択図】図１
