Bridge hinged support mounting method
The invention discloses a bridge hinged support installation method. The method comprises the following steps that S1, before a steel box girder is installed, a hinged support lower steel plate is in butt joint with a steel plate bolt embedded in the top face of a bridge abutment, and bolts are adopted for temporary fixing; s2, when the steel box girder is installed, the steel box girder is firstly placed in place, measured and adjusted in place, and then the steel box girder and the steel plate on the hinged support are connected and fixed in a spot welding mode; s3, the lower steel plate temporary fixing bolts are dismantled, the steel box girder communicating hinged support is lifted to the top face of a bridge abutment back wall, and therefore a construction space of a steel box girder bottom plate and a steel plate connecting weld joint on the hinged support is formed; s4, the steel box girder and the hinged support upper steel plate of the hinged support are subjected to full-length welding, and welding construction is completed; and S5, finally, the steel box girder and the hinged support integrally fall in place, a lower steel plate connecting bolt is screwed down, and installation is completed. The welding construction space is expanded, the operation condition is improved, the construction is efficient, and the construction safety is improved; the problem that efficient and safe construction cannot be achieved due to the limited space of the steel box girder and the hinged support is solved.
本发明公开了一种桥梁铰支座安装方法包括以下步骤：S1：钢箱梁安装前，将铰支座下钢板与桥台顶面预埋钢板螺栓进行对接并采用了螺栓临时固定；S2：钢箱梁安装时，先将钢箱梁进行就位并测量调整到位，接着钢箱梁与铰支座上钢板进行点焊连接固定；S3：拆除下钢板临时固定螺栓，将钢箱梁连通铰支座吊起提升至桥台背墙顶面，从而形成钢箱梁底板与铰支座上钢板连接焊缝的施工空间；S4：将钢箱梁和铰支座的铰支座上钢板满焊，完成焊接施工；S5：最后钢箱梁与铰支座整体下落就位，并拧紧下钢板连接螺栓，完成安装。其扩展了焊接施工空间，改善了作业条件，施工高效，提高了施工安全性；解决了钢箱梁与铰支座空间有限无法高效安全施工的问题。
