AI Technical Summary

Technical Problem

The construction efficiency of steel crossbeams between cable-stayed bridge towers is low, there are risks of installation and dismantling, and the construction cost is high. In particular, the inconsistent length of the crossbeams in bidirectional torsional structures makes hoisting difficult.

Method used

Positioning reflective stickers are set at the intended installation positions of the tower columns and steel beams, and temporary support plates are set below them. The positioning reflective stickers provide reference coordinates and support to ensure that the steel beams are hoisted into place in one go. T-shaped weld seam full penetration backing plate welding technology is adopted.

Benefits of technology

This improved construction efficiency, reduced construction costs, ensured the installation accuracy and safety of the steel beams, and avoided the impact of environmental changes on welding quality.

Abstract

本发明公开了一种斜拉桥索塔钢横梁施工方法,在索塔立柱与钢横梁预备安装位置处设置定位反光贴后,在定位反光贴下方设置用于支撑钢横梁的临时支撑板,钢横梁吊装时保证钢横梁与定位反光贴位置匹配以实现钢横梁一次性吊装到位。本发明的斜拉桥索塔钢横梁施工方法,施工流程简单,通过在理论安装位置安装定位反光贴和在定位反光贴下方设置临时支撑板,既方便钢横梁长度的测算,直观地为钢横梁的安装提供参考位置,又提高了索塔与钢横梁焊接时钢横梁姿态的可控性,能够实现钢横梁一次性吊装到位,其施工效率高,不存在安拆风险,施工成本低,极具应用前景。
