DISPLACEMENT RESTRICTION DEVICE
To provide a compact displacement restriction device having a great cushioning effect over the entire directions around a building by, for example, setting in a base-isolated building.SOLUTION: A displacement restriction device has a first member 15 fixed to a face of one structure 10, an annular second member 16 fixed to the face of the other structure 11, and a third member 18 arranged between the first member 15 and the second member 16. The first member 15 and the third member 18 are connected with each other via an annular laminated rubber 17. The third member 18 has a columnar first projection 21 extending inward the second member 16, the first member 15 has a columnar second projection 20 extending inward the laminated rubber 17, and the second member 16 forms a first stopper allowing abutting of the first projection 21 thereto. The third member 18 has a second stopper 22b allowing abutting of the second projection 20 thereto.SELECTED DRAWING: Figure 2
【課題】例えば免震建物に設置されることにより、コンパクトな構造で、建物周囲全方向に亘って大きな緩衝効果を期待することができる、変位制限装置を提供する。【解決手段】一方の構造物１０の面に固定された第１部材１５と、他方の構造物１１の面に固定された環状の第２部材１６と、第１部材１５と第２部材１６との間に配置された第３部材１８とを備え、第１部材１５及び第３部材１８は、両部材間に挟まれた環状の積層ゴム１７を介して連結され、第３部材１８には、第２部材１６の内方に延びる柱状の第１突起２１が設けられ、第１部材１５には、積層ゴム１７の内方に延びる柱状の第２突起２０が設けられ、第２部材１６は第１突起２１が当接可能な第１ストッパーを構成し、第３部材１８には第２突起２０が当接可能な第２ストッパー２２ｂが設けられている。【選択図】図２
