Steel arch bridge inward-inclining arch rib and arch support combined section installation method
The invention discloses a steel arch bridge inward-inclining arch rib and arch support combined section installation method. The method comprises the steps that the joint of any two adjacent segmentsin an arch rib is determined; for each joint, at least one bearing support is arranged at the lower end of the joint, the upper end of each bearing support is provided with an elevation adjusting device corresponding to the two subsections included in the joint, and the bearing supports are connected with the corresponding subsections through the elevation adjusting devices; an embedded plate is arranged at the position, used for being connected with the subsection, of the arch support, an L-shaped groove-shaped limiting plate is welded to the embedded plate, and a position adjusting device used for adjusting the space arch rib is arranged in a groove of the limiting plate; and the elevation of the corresponding subsection is adjusted through the elevation adjusting device, and the position of the space arch rib is adjusted through the position adjusting device. The technical problem of how to locate and guarantee the mounting precision of the arch rib and arch support connecting section in the prior art can be solved.
本申请公开了一种钢拱桥内倾拱肋与拱座结合段安装方法。该方法包括：确定拱肋中任意相邻的两个分段的连接处；对于每个所述连接处，在该连接处下端设置至少一个承力支架，其中，每个所述承力支架上端设置对应该连接处包括的两个分段的标高调节装置，通过所述标高调节装置与对应的所述分段相连接；在拱座上用于连接所述分段位置上设置预埋板，在所述预埋板上焊接呈L形状槽型的限位板，且所述限位板的槽内设置用于调节空间拱肋的位置调节装置；通过标高调节装置调整对应的所述分段的标高以及通过位置调节装置调节空间拱肋位置。本申请可以解决相关技术中如何定位保证拱肋与拱座连接段安装精度的技术问题。
