大跨度穹顶网壳钢结构吊装技术研究

STUDY ON HOISTING TECHNOLOGY FOR LARGE-SPAN STEEL RETICULATED DOME STRUCTURE

北京某大型乐园穹顶钢结构工程大跨度网壳钢结构吊装充分利用胎架支撑高空拼装的形式进行安装,在穹顶内部提前开通一条吊装通道,通过合理规划施工顺序,逐步完成环梁穹形梁施工,提高安全性和施工效率,可为同类型网壳钢结构工程提供参考。

In a large park in Beijing,the large-span steel reticulated dome structure was erected by means of high-altitude assembly with a jig.A hoisting channel was made in advance inside the dome,and the ring beams of the dome were completed gradually according to a reasonable construction sequence,with high safety and construction efficiency.This construction technology provides a reference for similar steel reticulated dome structures.
