摘要
汉国城市商业中心工程结构总高度为311.9m,塔楼设置4个避难层,每个避难层设计有钢结构伸臂桁架,通过优化桁架拼装的分段设计、增加桁架间的稳固梁等措施,实现了桁架的轴线偏差≤5mm、垂直度偏差≤10mm,并通过实践,总结了避难层桁架的施工工法,在确保施工进度及工作性能的同时,提高了避难层桁架的施工质量。
The total height of Hanguo City Commercial Center project structure is 311.9m,and four refuge floors have been set in tower.Each refuge floor sets the steel suspended truss.Through optimization of truss erection of the sectional design,Increasing the stable beam between the truss,the truss axis deviation is less than 5mm and the vertical deviation is less than 10mm.Through the practice,the construction method of refuge floor truss is summarized,the progress and work performance of construction is ensured and the quality of construction quality of the refuge floor truss is improved.
