Abstract

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.

Description

technical field [0001] The present application relates to the technical field of bridge engineering, in particular to a method for installing a joint section between an inclining arch rib and an abutment of a steel arch bridge. Background technique [0002] With the continuous development of urban bridge construction, many bridges not only play the role of transportation hub, but also play an ornamental role, especially around scenic spots. Steel structure arch bridges are becoming more and more popular due to their beautiful lines, excellent spans and navigation capabilities. [0003] The abutment is the key stress-bearing part in the arch bridge, which transfers the thrust of the arch rib to the ground through the abutment. For inwardly inclined spatial arch ribs, how to position and ensure the installation accuracy of the connecting section between the arch rib and the abutment is a difficult problem in completing the installation of the arch bridge. [0004] Therefore,...
