DISPLACEMENT REGULATING DEVICE
To provide a displacement regulating device capable of regulating the displacement in the horizontal direction of an upper side structure supported by a lower side structure, preventing excess stress of the lower side structure at the time of an earthquake and being easily installed on an existing structure.SOLUTION: A displacement-regulating member 11 of a displacement-regulating device 10 is brought into contact with a lower shoe 8b fixed to a stiffening girder 6 side to regulate the horizontal displacement of floor framing 5 with respect to the stiffening girder 6, and the horizontal force applied from the floor framing 5 side to the stiffening girder 6 side is smaller than the allowable stress of the stiffening girder 6, to release the regulation of the displacement by the displacement-regulating member 11, so that stress excess of the stiffening girder 6 does not occur during an earthquake. Since the displacement-regulating member 11 is mounted to be brought into contact with the lower shoe 8b of the movable bearing 8, it is not necessary to replace the movable bearing 8 with a fixed bearing or a base isolation rubber bearing.SELECTED DRAWING: Figure 9
【課題】下部側構造物に支持された上部側構造物の水平方向への変位を規制することができるとともに、地震時における下部側構造物の応力超過を防止することができ、更には既設構造物への設置も容易に行うことのできる変位規制装置を提供する。【解決手段】補剛桁６側に固定された下沓８ｂに変位規制装置１０の移動規制部材１１を当接することにより、補剛桁６に対する床組５の水平方向への変位を規制するとともに、床組５側から補剛桁６側に加わる水平方向の力が補剛桁６の許容応力よりも小さい力で変位規制部材１１による変位規制が解除されるようにしたので、地震時における補剛桁６の応力超過を生ずることがない。また、移動規制部材１１が可動支承８の下沓８ｂに当接するように取り付けられるので、可動支承８を固定支承や免震ゴム支承に交換する必要がない。【選択図】図９
