To reduce a tensile force acting on a base isolation device at the time of an earthquake without increasing the number of installation of base isolation devices.SOLUTION: A base isolation structure 10 includes a lower structure 20, a seismic isolation device 12 provided on the lower structure 20, an upper structure 30 supported by the lower structure 20 via the seismic isolation device 12, a load receiving member 60 rotatably connected to the lower structure 20, a load transmission member 70 rotatably connected to the upper structure 30 and placed in an obliquely lower position of the load receiving member 60, and a guide rod 76 for connecting the load receiving member 60 and the load transmission member 70 to each other so as to be relatively displaceable, and guiding the load transmission member 70 to the load receiving member 60 in accordance with the relative displacement of the lower structure 20 and the upper structure 30 in the horizontal direction.SELECTED DRAWING: Figure 3
【課題】本発明は、免震装置の設置数を増やすことなく、地震時に免震装置に作用する引張力を低減することを目的とする。【解決手段】免震構造物１０は、下部構造体２０と、下部構造体２０に設けられる免震装置１２と、免震装置１２を介して下部構造体２０に支持される上部構造体３０と、下部構造体２０に回転可能に連結される荷重受け部材６０と、上部構造体３０に回転可能に連結されるとともに、荷重受け部材６０の斜め下方に配置される荷重伝達部材７０と、荷重受け部材６０と荷重伝達部材７０とを相対変位可能に連結するとともに、下部構造体２０と上部構造体３０との水平方向の相対変位に伴って、荷重伝達部材７０を荷重受け部材６０へ誘導するガイドロッド７６と、を備える。【選択図】図３
