MOVEMENT RESTRAINT DEVICE OF BEARING

PROBLEM TO BE SOLVED: To provide a movement restraint device of a bearing, the device that reliably restrains the movement of the bearing and is not damaged by abutment due to the movement of a specific bearing even if installed to each of multiple bearings, respectively, and thereby can restrain the movement of the multiple bearings integrally.SOLUTION: A movement restraint device 3 of a bearing is installed at a predetermined distance from the side surface of the bearing 2 of a bridge, and includes: a base 31 fixed to a pier 1; a die 32 having a cylindrical hollow part opened on a base toward the lateral direction of the bearing; and a rod 33 fitted to the cylindrical hollow part of the die so as to protrude toward the lateral direction of the bearing. The movement of the bearing is restrained by the frictional resistance between the die and the rod, when a portion of the side surface of the bearing comes into abutment with the rod with the movement of the bearing.SELECTED DRAWING: Figure 1 【課題】支承の移動を確実に拘束するとともに、複数の支承それぞれに対して設置した場合でも、特定の支承の移動による当接により破損せず、複数の支承の移動を一体的に拘束することが可能な支承の移動拘束装置を提供する。【解決手段】橋梁の支承２の側面から所定の距離をおいて設置される支承の移動拘束装置３であって、橋脚１に固定された基台３１と、基台に支承の側面方向に向けて開口した筒状中空部を有するダイス３２と、ダイスの筒状中空部に支承の側面方向に向けて突出するように嵌合されたロッド３３を備え、支承の移動に伴い、支承の側面の一部がロッドに当接した際に、ダイスとロッドの摩擦抵抗により支承の移動を拘束する。【選択図】図１
