摘要
以深圳某大跨度悬挑钢桁架屋盖结构实际案例为背景,深入分析了高空嵌补、分段分节吊装和整体提升3种施工方案的优缺点。综合考虑成本和工期优势,进行施工方案比选,根据比选结果选定整体提升施工。根据本项目结构特点,介绍了整体提升施工工艺,关键技术控制措施和提升分析验算情况,为类似项目施工提供参考。
Based on the actual case of a large-span cantilevered steel truss roof structure in Shenzhen,this paper deeply analyzes the advantages and disadvantages of three construction schemes,such as high-altitude nesting,segmenting hoisting and overall lifting.Considering the cost and time limit for a project,construction scheme comparison.Select the overall lifting construction scheme according to the comparison results.According to the structural characteristics of the project,this paper also introduces the overall lifting construction technology,key technical control measures and lifting analysis,which provides reference for similar project construction.
