Large-span steel cover beam construction method based on steel support
The invention discloses a large-span steel cover beam construction method based on a steel support, which comprises the following steps: adding a pier top steel support between gate-type pier columns, firstly arranging a bracket structure during construction, then installing the steel support on the bracket structure, and installing a steel cover beam after a frame structure is formed between the steel support and the pier columns. The structure and the construction sequence are improved, the load of the upper structure is borne by the steel support and the steel cover beams together, the stress condition of the steel cover beam structure is improved, the pier top is reinforced through the steel support, and the construction efficiency is improved. In the construction process, the steel support can serve as a support to support and adjust the position of the block structure of the steel cover beam, and the construction difficulty and the safety risk of the pier and the pier top when the cover beam is fixedly connected with the bridge in a traditional construction scheme are reduced.
本发明公开了一种基于钢支撑的大跨径钢盖梁施工方法，在门式墩柱之间增设墩顶钢支撑，施工中先设置牛腿结构，然后在牛腿结构上安装钢支撑，钢支撑与墩柱之间形成框架结构后安装钢盖梁，对钢盖梁以钢盖梁受力反弯点为界分块安装钢盖梁，最后浇筑混凝土固结墩顶与钢盖梁，形成整体受力体系，通过上述结构及施工顺序改进，上部结构荷载由钢支撑与钢盖梁共同承担，改善了钢盖梁结构的受力情况，利用钢支撑加固墩顶，提高了墩顶位置处的承载能力，施工过程中钢支撑可作为支架对钢盖梁的分块结构进行支撑和调位，减小了传统施工方案中盖梁与桥梁固结时桥墩及墩顶的施工困难及安全风险。
