SEISMIC ISOLATOR
PROBLEM TO BE SOLVED: To provide a seismic isolator capable of generating a viscous resistance stably and attenuating vibrations.SOLUTION: A seismic isolator 1 to be installed between a superstructure 20 and a substructure 21 comprises: a first connection part 2 connected to the superstructure 20; a second connection part 3 connected to the substructure 21; an expansion mechanism 10 arranged between the first connection part 2 and the second connection part 3, and including a first arm part 11 and a second arm part 12 extending to intersect the first arm part 11 so that the first arm part 11 and the second arm part 12 rotate in directions opposite to each other, then extends and contracts in accordance with the adjacent-alienation actions of the first connection part 2 and the second connection part 3; a storage part 4 mounted on the first arm part 11 for storing a viscous body 6; and a resistance plate 5 attached to the second arm part 12 and dipped in the viscous body 6 of the storage part 4. As the expansion mechanism 10 extends and contracts, the storage part 4 and the resistance plate 5 rotate in directions opposed to each other.SELECTED DRAWING: Figure 1
【課題】 安定して粘性抵抗力を発生させることができ、振動を減衰させることが可能な免震装置を提供する。【解決手段】 上部構造体２０と下部構造体２１との間に設置される免震装置１は、上部構造体２０に連結された第１連結部２と、下部構造体２１に連結された第２連結部３と、第１連結部２と第２連結部３との間に配置され、第１腕部１１と第１腕部１１に対し交差するように延びる第２腕部１２とを有し、第１連結部２および第２連結部３の近接・離間動作に伴って第１腕部１１と第２腕部１２とが互いに逆方向に回転して伸縮する伸縮機構１０と、第１腕部１１に取り付けられ、粘性体６を収容する収容部４と、第２腕部１２に取り付けられ、収容部４の粘性体６に浸かる抵抗板５と、を備え、伸縮機構１０が伸縮することにより、収容部４と、抵抗板５とが互いに逆方向に回転する。【選択図】図１
