Dismounting and mounting method for large-span roof and net rack steel structure
The invention belongs to the technical field of building construction, and discloses a method for dismantling and installing a large-span roof and a grid steel structure, which comprises the following steps of: obtaining a reconstruction area of an old steel structure roof, and dividing the reconstruction area into a plurality of reconstruction sub-areas; a supporting scaffold is erected and removed, and a conversion support is arranged; the old steel structure roof is dismantled in the first direction; the dismantling supporting scaffolds corresponding to the two stand areas are dismantled, old concrete structures corresponding to the stand areas are transformed, and two reconstructed concrete structures are formed; supporting scaffolds are erected and installed on the two rebuilt concrete structures correspondingly, and conversion supports are arranged on the two rebuilt concrete structures correspondingly; the conversion support is adjusted, and the newly-built steel structure roof is hoisted and installed in the direction opposite to the first direction; the newly-built steel structure roof is unloaded; and dismantling the scaffold. By means of the method, the old roof and the old roof structure can be efficiently dismantled, the influence on the concrete structure is effectively reduced, and during construction, the safety is high, the construction progress is fast, and the efficiency is high.
本发明属于建筑施工技术领域，公开了一种大跨度屋面及网架钢结构的拆除和安装方法，包括：获取旧有钢结构屋面的改建区域，将改建区域划分为多个改建子区域；搭设拆除支撑脚手架，并设置转换支撑；沿第一方向拆除旧有钢结构屋面；拆除对应于两个看台区域的拆除支撑脚手架，对与看台区域对应的旧有混凝土结构进行改造，形成两个改建混凝土结构；在两个改建混凝土结构上分别搭设安装支撑脚手架，并分别设置转换支撑；调整转换支撑，沿第一方向的反方向进行新建钢结构屋面的吊装安装；对新建钢结构屋面进行卸载；拆除脚手架。此方法能高效地拆除旧的屋面及其结构，且有效减少对于混凝土结构的影响，施工时的安全性高，施工进度快、效率高。
