Large-span net rack dome ring-by-ring assembling and staged jacking construction method
The invention relates to the technical field of building construction, in particular to a large-span net rack dome ring-by-ring assembling and staged jacking construction method which comprises the steps of construction preparation and embedded part rechecking. Assembling a central steel platform on the ground; a central area jacking frame and a net rack are installed, and first-time jacking is conducted; mounting a second circle of net rack and a jacking frame, and jacking for the second time; a third circle of net rack and a jacking frame are installed, and when jacking reaches the designed elevation, the jacking frame and the jacking frame are dismantled; fireproof paint and finish paint are constructed; performing final acceptance inspection; the construction method has the beneficial effects that construction procedures are optimized, procedure interpenetration is facilitated, the aerial work amount of construction workers is greatly reduced, the construction safety and the construction progress of the whole grid structure are guaranteed, the grid installation quality is improved, and the like, and the construction quality improvement effect is achieved; the method is simple in form and convenient to operate and implement on site; in addition, construction efficiency is high, construction period is saved, and construction cost is reduced.
本发明涉及建筑施工技术领域，具体为一种大跨度网架穹顶分圈拼装分阶段顶升施工方法，包括：施工准备、埋件复核；中央钢平台地面拼装；中心区顶升架以及网架的安装，进行第一次顶升；安装第二圈网架和顶升架，进行第二次顶升；安装第三圈网架和顶升架，当顶升到达设计标高后进行顶升架及回顶架的拆除；进行防火涂料、面漆的施工；最终验收检查；有益效果为：优化了施工工序，有利于工序穿插，大幅降低了施工作业人员高空作业量，保证了整个网架结构的施工安全和施工进度，提高网架安装质量等一系列目标，为工程提质创效；并且形式简单，操作方便，便于现场实施；另外施工效率高，节省工期，降低施工成本。
