The invention discloses a cable-stayed bridge cable bent tower steel cross beam construction method which comprises the following steps: after positioning reflective stickers are arranged at preparation mounting positions of cable bent tower stand columns and steel cross beams, temporary supporting plates for supporting the steel cross beams are arranged below the positioning reflective stickers; when the steel cross beam is hoisted, the steel cross beam is matched with the positioning reflective stickers in position so that the steel cross beam can be hoisted in place at a time. According to the cable-stayed bridge cable tower steel cross beam construction method, the construction process is simple, the positioning reflective stickers are installed at the theoretical installation positions, and the temporary supporting plates are arranged below the positioning reflective stickers, so that the length of the steel cross beam is conveniently measured and calculated, and a reference position is visually provided for installation of the steel cross beam; the controllability of the posture of the steel cross beam during welding of the cable bent tower and the steel cross beam is improved, the steel cross beam can be hoisted in place at a time, the construction efficiency is high, mounting and dismounting risks do not exist, the construction cost is low, and the application prospect is great.
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。
