Multi-beam-falling-prevention friction pendulum support for bridge
The invention discloses a multiple anti-falling friction pendulum support for a bridge, and relates to the bridge support technology, the multiple anti-falling friction pendulum support comprises an upper cover plate fixedly connected to a bridge body and a lower bottom plate fixedly connected to a bridge pier, a middle lining plate is fixed at the lower end of the upper cover plate, a cavity is formed between the middle lining plate and the lower bottom plate, a spherical crown plate is arranged in the cavity, and the spherical crown plate is fixedly connected with the upper cover plate. The spherical crown plate is connected between the middle lining plate and the lower bottom plate, a cylindrical hole is formed in the middle of the spherical crown plate, tenons are fixedly connected to the middle of the lower end face of the middle lining plate and the middle of the upper end face of the lower bottom plate, and the tenons extend into the cylindrical hole. According to the multi-beam-falling-prevention friction pendulum support for the bridge, the overall structure of the support adopts a separated design of normal displacement and earthquake displacement, and the normal displacement and the earthquake displacement do not interfere with each other; triple beam falling prevention defensive lines are arranged in the friction pendulum support, the third beam falling prevention defensive line is used for preventing beam falling in an earthquake through two clamping tenons, the earthquake displacement distance can be increased, and double limiting can be carried out to ensure the beam falling prevention effect.
本发明公开了一种桥梁多重防落梁摩擦摆支座，涉及桥梁支座技术，包括固接在桥梁梁体上的上盖板和固接在桥墩上的下底板，所述上盖板下端固定有中衬板，所述中衬板与下底板之间形成有空腔，所述空腔内设置有球冠板，所述球冠板连接在中衬板与下底板之间，所述球冠板中部开设有圆柱孔，所述中衬板下端面中部和所述下底板上端面中部均固接有卡榫，所述卡榫延伸至圆柱孔内。本发明提供的一种桥梁多重防落梁摩擦摆支座，支座整体结构采用正常位移与地震位移的分离式设计，各不干涉；摩擦摆支座内部设置了三重防落梁防线，其中，第三重防落梁防线是利用两个卡榫用来防止地震下的落梁，既可以扩大地震位移间距，还可以进行双重限位以确保防落梁效果。
