Small-displacement limiting swing bridge
The invention discloses a small-displacement limiting swing bridge, and belongs to the technical field of bridge structures, the small-displacement limiting swing bridge comprises a beam body, a pier and a bearing platform, prestressed tendons penetrating through the pier are arranged between the beam body and the bearing platform, a displacement groove is formed in the bottom of the beam body, and a cavity coaxial with the displacement groove is formed in the beam body; the cavity is provided with a plurality of connecting grooves communicating with the displacement groove, rotating shafts are rotationally connected into the connecting grooves, and telescopic structural devices are fixed to the bottoms of the rotating shafts. A connecting plate in sliding connection with the displacement groove is fixed to the top end of the bridge pier, and the telescopic structural devices are hinged to the peripheral side of the connecting plate; a limit locking device is arranged in the cavity and used for locking all the rotating shafts when one rotating shaft deflects to the limit. The invention aims to solve the problems that the connection performance between a beam body and a pier is changed due to the deformation of the beam body under the action of temperature, and the overall anti-seismic performance of a bridge is greatly influenced.
本发明公开了一种小位移限位摇摆桥梁，属于桥梁结构技术领域，包括梁体、桥墩与承台，所述梁体与承台之间设置有贯穿桥墩的预应力筋，所述梁体底部开设有位移槽，所述梁体内部开设有与位移槽同轴线的腔室，所述腔室开设有若干与位移槽连通的连接槽，所述连接槽内均转动连接有转轴，所述转轴底部均固定有伸缩结构器；所述桥墩顶端固定有与位移槽滑动连接的连接板，所述伸缩结构器均与连接板周侧铰接；所述腔室内设置有极限锁定装置，所述极限锁定装置用于在其中一个转轴偏转至极限时对所有转轴进行锁定；本发明的目的在于解决梁体在温度作用下会发生变形，导致梁体与桥墩之间的连接性能发生改变，对桥梁整体抗震性能产生较大影响的问题。
