Arch steel beam mounting method
The invention discloses a method for installing a steel beam on an arch. The method comprises the following steps that S1, an arch ring, a stand column on the arch, a cable and a cantilever hanging bracket are built; s2, the single steel beam is transported to the position below an arch ring of the bridge in a water transportation mode; s3, the cantilever hanging bracket lifts the single steel beam; s4, a lifting hook is installed, and relay lifting is conducted through the lifting hook of the cable; s5, the single steel beam is fixed to a support transverse partition plate of the on-arch stand column; s6, splicing and assembling of a plurality of single steel beams on the same side are completed; and S7, a winch of the cantilever hanging bracket is adjusted to the other side, and the single steel beam on the other side of the arch ring is hoisted and installed. The steel beams on the arch are large super-wide and super-heavy components, and a large amount of transportation cost can be saved when the steel beams are transported on water compared with highway transportation; after the steel beam is transported to a bridge site, a method of directly hoisting and mounting on water is adopted, so that the transfer process from water to land is avoided, the transfer cost is reduced, and the land transportation road construction cost and the assembly site construction cost are also avoided.
本发明公开了一种拱上钢梁安装方法，包括如下步骤：S1、搭建拱圈、拱上立柱、缆索及悬臂吊架；S2、通过水运方式将单片钢梁运至桥梁的拱圈下方；S3、悬臂吊架将单片钢梁提升；S4、安装吊钩，通过缆索的吊钩接力吊装；S5、将单片钢梁固定在拱上立柱的支座横隔板；S6、完成同一侧多个单片钢梁的拼合组装；S7、悬臂吊架的卷扬机调整至另一侧，进行拱圈另一侧的单片钢梁的起吊安装。本发明，拱上钢梁为大块超宽超重构件，钢梁采用水上运输相比公路运输可节约大量运输费；钢梁水运至桥址后，采用水上直接起吊安装方法，避免了水上转为陆地的转运过程，减少了转运费用，也避免了陆地运输道路建设费和拼装场地建设费用。
