SEISMIC ISOLATION STRUCTURE WITH FAILSAFE MECHANISM
PROBLEM TO BE SOLVED: To provide a seismic isolation structure with a failsafe mechanism which avoids the collapse and breakage of a building even if an assumed disastrous giant earthquake and a supergiant earthquake exceeding an assumption occurs, is high in versatility for protecting a human face, and comprises a failsafe system.SOLUTION: A failsafe mechanism 10 for regulating the relative displacement of an upper structure with respect to a lower structure of a building is arranged at a seismic isolation layer. The failsafe mechanism 10 comprises: an abutment part 11 which is arranged at the upper structure integrally therewith, and arranged in the seismic layer; a displacement regulation main body part 12 which is arranged at the lower structure integrally therewith, protrusively arranged in the seismic layer, and regulates the relative displacement of the upper structure with respect to the abutment part 11 and the lower structure by abutting on the abutment part 11 when displacement exceeding the preset relative displacement amount of the upper structure with respect to the lower structure occurs; and a buffer part 13 which is arranged between the abutment part 11 and the displacement regulation main body part 12.
【課題】想定される最大級の巨大地震や、想定を超える超巨大地震が発生した場合においても、建物を倒壊・崩壊させず、人面を保護できるような汎用性が高いフェールセイフシステムを備えたフェールセイフ機構付き免震構造を提供する。【解決手段】免震層に、建物の下部構造体に対する上部構造体の相対変位を規制するフェールセイフ機構１０を設ける。フェールセイフ機構１０を、上部構造体に一体に設けられるとともに免震層内に配設された当接部１１と、下部構造体に一体に設けられるとともに免震層内に突設され、予め設定した下部構造体に対する上部構造体の相対変位量を超える変位が発生した際に当接部１１が当たって当接部１１及び下部構造体に対する上部構造体の相対変位を規制する変位規制本体部１２と、当接部１１と変位規制本体部１２の間に設けられる緩衝部１３とを備えて構成する。【選択図】図３
