Large-span space grid steel roof structure and construction technology
The invention relates to the technical field of large-span net rack construction, and provides a large-span space grid steel roof structure and a construction technology, and the construction technology comprises the following steps: step 1, lifting block floor assembly; secondly, a lifting supporting system is arranged; 3, a computer controls hydraulic synchronous lifting; step 4, folding and inlaying; step 5, unloading; step 6, construction monitoring; according to the method, construction is conducted in a floor splicing and block lifting mode, high-altitude splicing and high-altitude welding are transferred to a floor, the net rack splicing height is effectively lowered, the high-altitude splicing and welding workload is reduced, the safety risk can be better lowered, the construction quality can be better controlled, the construction progress can be better accelerated, and the construction cost can be better saved; and meanwhile, the influence on surrounding matching projects is reduced, the problem that a large crane cannot be directly hoisted due to site limitation in the prior art is solved, and compared with the prior art, the method has obvious economic benefits and social benefits.
本发明涉及大跨度网架施工技术领域，提出了一种大跨度空间网格钢屋盖结构及施工工艺，包括以下步骤：步骤一，提升分块楼面拼装；步骤二，提升支撑系统设置；步骤三，计算机控制液压同步提升；步骤四，合拢嵌补；步骤五，卸载；步骤六，施工监测；本发明采用楼面拼装，分块提升方式施工，将高空拼接、高空焊接这些工作转移到楼面，有效的低了网架拼装高度及减少高空拼接焊接工作量，能更好的降低安全风险、控制施工质量、加快施工进度、节约施工成本，同时减少对周边配套工程的影响，解决了现有技术受场地限制大型吊机不能直接吊装的问题，相对于现有技术来说本发明具有明显的经济效益和社会效益。
