SEISMIC ISOLATION APPARATUS

KOCHIYAMA OSAMU / NAGAHIRO KENTA / KIMURA YASUNARI

A seismic isolation apparatus includes a laminated body having alternately laminated rubber plates and steel plates; a hollow portion provided inside the laminated body in a hermetically closed manner and extending in a laminated direction; a lead plug filled densely in the hollow portion and adapted to damp the vibration in a shearing direction of the laminated body by absorbing vibrational energy in the shearing direction; and a lid member having a semispherical concave surface which comes into contact with one end portion in the laminated direction A of the lead plug in order to guide and assist the plastic flow of the lead plug at one end portion in the laminated direction of the hollow portion in the deformation in the shearing direction of the lead plug.
