Bolting and welding combined steel truss girder large segment assembling method
The invention relates to a bolting and welding combined steel truss girder large segment assembling method. The method is characterized by specifically comprising the following steps that S1, truss pieces are assembled; S2, an upper-layer bridge floor is assembled; S3, a lower-layer bridge floor is assembled; and S4, the whole sections are assembled. A continuous assembling mode is adopted, the truss pieces, the upper-layer bridge floor and the lower-layer bridge floor are independently installed in a multi-turn mode, a section is reserved on the basis of the previous-turn assembly to serve asa mother section of the next turn to participate in installation, and therefore smooth connection between adjacent structures can be guaranteed, and the installation precision is guaranteed. The lastone of the lower-layer bridge floor, the truss pieces and the upper-layer bridge floor is sequentially assembled and then disassembled, loaded and transported to be assembled on site, so that the overall assembling efficiency of the steel truss girder large segments is improved, and the assembling precision is guaranteed.
本发明涉及一种栓焊结合钢桁梁大节段拼装方法，其特征在于：具体拼装方法如下：S1：桁片拼装；S2：上层桥面拼装；S3：下层桥面拼装；S4：整节段拼装；本发明中采用连续拼装的方式，桁片、上层桥面、下层桥面均采用多轮独立安装且在上一轮拼装的基础上留下一段作为下一轮的母段参与安装，从而可以保证相邻的各结构之间的顺利连接从而保证安装的精度；采用由下层桥面、桁片、上层桥面的拼装顺序依次拼装最后一个再解体装运现场拼装，提高了钢桁梁大节段的整体拼装效率，保证了拼装精度。
