DISPLACEMENT RESTRICTION DEVICE
To provide a displacement restriction device that can be attached to, for example, a base-isolated building to avoid collisions between the building and a retaining wall due to excessive deformation of a base-isolating device.SOLUTION: A displacement restriction device according to an embodiment of the present invention includes: a cylindrical body 15 connected at one end to a face of one structure; and a rod 16 connected at one end to a face of the other structure. At both ends of the cylindrical body 15, movable end plates 24a and 24b are provided so as to be at right angles to the axial line of the cylindrical body and movable in the axial line direction. The other end of the rod 16 is inserted into the inside of the cylindrical body 15 through the movable end plate 24b of the other end of the cylindrical body 15 movably in the axial line direction. And the other end of the rod 16 is provided with a head 28 that is slidable in the axial line direction in the inner periphery of the cylindrical body 15 and moves the movable end plates 24a, 24b. An energy absorbing member 29 made of low yield point steel is provided between each end plate 24a, 24b and the middle portion of the outer circumference of the cylindrical body 15, extending in the axial line direction of the cylindrical body.SELECTED DRAWING: Figure 2
【課題】例えば免震建物に付随して設置されることにより、免震装置の過大変形による建物と擁壁との衝突を回避することができる、変位制限装置を提供する。【解決手段】一方の構造物の面に一方の端部が連結された筒状体１５と、他方の構造物の面に一方の端部が連結されたロッド１６とを備え、筒状体１５の両端部には、該筒状体の軸線に対して直角であって軸線方向に移動自在に可動端板２４ａ、２４ｂが設けられ、ロッド１６の他方の端部は１５筒状体の他方の端部の可動端板２４ｂを軸線方向に移動自在に貫通して筒状体１５の内方に挿入され、ロッド１６の他方の端部には筒状体１５の内周を軸線方向に摺動自在であって可動端板２４ａ、２４ｂを移動させるヘッド２８が設けられ、各端板２４ａ、２４ｂと筒状体１５の外周中間部との間に該筒状体の軸線方向に延びる、低降伏点鋼からなるエネルギー吸収部材２９が設けられている。【選択図】図２
