摘　　要：针对超高空双子塔屋面钢桁架施工难题,主要分析超高空屋面大跨度桁架及抗风桁架施工工艺,分析屋面钢结构空间布局,根据现场机械、环境、工期等施工条件,综合考虑选用“构件分段+整体吊装”相结合的方案,有效解决了超高层屋面大跨度桁架及抗风桁架施工过程稳定性差的难题,降低高空作业安全隐患,确保施工质量与安全,提高施工效率。In response to the construction difficulties of steel trusses on the roof of super high altitude twin towers,this paper mainly analyzes the construction technology of large-span trusses and wind resistant trusses on super high altitude roofs,analyzes the spatial layout of roof steel structures,and comprehensively considers the combination of"component segmentation+whole lifting"based on on-site mechanical,environmental,and construction conditions.This effectively solves the problem of poor stability in the construction process of large-span trusses and wind resistant trusses on super high altitude roofs,reduces safety hazards in high-altitude operations,ensures construction quality and safety,and improves construction efficiency.
