Hidden longitudinal settlement joint of double-width bridge and construction method
The invention provides a hidden longitudinal settlement joint of a double-width bridge. The hidden longitudinal settlement joint comprises double bridges arranged on the two sides of a bridge reserved seam, wherein pre-embedded steel plates are arranged at the preset horizontal positions of a first bridge body and a second bridge body, a sliding steel plate is fixedly connected to the upper part of the first pre-embedded steel plate, the other end of the sliding steel plate is placed on the upper part of the second pre-embedded steel plate, a polyfluortetraethylene plate is pasted on the second embedded steel plate, the friction coefficient of the polyfluortetraethylene plate and the sliding steel plate on the second embedded steel plate is reduced, and the sliding steel plate is arranged in an asphalt pavement layer. According to the invention, the requirements of transverse free expansion and vertical differential settlement of the double-width bridge are met, and the structure is hidden on the bridge floor, so that the aesthetic property of the bridge and the driving comfort are improved. In addition, the steel plate is embedded in the pavement layer, so that the corrosion opportunity is reduced, and the service life of the settlement joint is also prolonged.
本发明提供一种双幅桥梁的隐藏式纵向沉降缝。本发明包括设置在桥梁预留缝两侧的双幅桥梁，第一幅桥梁梁体和第二幅桥梁梁体均在预设水平位置设有预埋钢板，其中第一预埋钢板上方固定连接有滑动钢板，所述滑动钢板另一端放置在第二预埋钢板上方，第二预埋钢板上方粘贴聚四氟乙烯板，减小了同上方滑动钢板的摩擦系数，所述滑动钢板布置在沥青铺装层内。本发明解决了双幅桥梁横向自由伸缩及竖向不均匀沉降的需求，又在桥面上隐藏了此种结构，增加桥梁的美观性及行车舒适型。并且由于钢板埋设到铺装层内，减小了被腐蚀的机会，沉降缝的寿命也得到了延长。
