Sliding step-by-step external expansion jacking method applied to large-span steel truss construction
The invention relates to the technical field of steel structure net rack construction, in particular to a sliding step-by-step external expansion jacking method applied to large-span steel net rack construction, which comprises the following steps: S1, starting assembly of net rack units; s2, the tank slides; s3, the net rack units are jacked in a segmented mode; s4, performing segmented external expansion on the net rack units; and S5, overall jacking of the net rack unit is carried out. According to the sliding step-by-step external expansion jacking method applied to construction of the large-span steel truss, firstly, in-situ assembly of the truss units is carried out, then segmented jacking, segmented external expansion and overall jacking of the truss units are sequentially carried out under the cooperation of a tank and a field tower crane till the truss units are jacked to the designed elevation position, and finally the truss units are assembled. The installation problem caused by site limitation is solved, the aerial workload is reduced, the net rack installation quality is guaranteed, the construction efficiency is improved, and the technical problem that segmented assembly and segmented jacking are carried out due to the fact that jacking cannot be carried out in place at a time under different elevation assembly faces is solved.
本发明涉及钢结构网架施工技术领域，尤其涉及应用在大跨度钢网架施工中的滑移分步外扩顶升方法，包括以下步骤：S1，网架单元的起步组装；S2，坦克车滑移；S3，网架单元的分段顶升；S4，网架单元的分段外扩；S5，网架单元的整体顶升。本发明提供的应用在大跨度钢网架施工中的滑移分步外扩顶升方法，首先进行网架单元的原位组装，然后在坦克车、现场的塔吊配合下依次进行网架单元的分段顶升、分段外扩和整体顶升，直至顶升至设计的标高位置，解决了因场地受限带来的安装的问题，减少了空中工作量，保证了网架安装质量，提高了施工效率，也解决了在不同标高组装面下一次性顶升不能顶升到位而进行分段组装分段顶升的技术难题。
