弦支穹顶结构施工技术措施研究

Research on Construction Technology Measures of Suspend-dome Structure

弦支穹顶是一种新型的预应力大跨度空间建筑结构,由于其受力合理、经济美观等优点,被广泛应用于体育馆、航站楼等大型公共建筑中。随着弦支穹顶结构的大规模使用,其结构形式在不断改进,这就无形中增加了现场的施工难度,如何确保其顺利施工是目前研究的热点,与其相关的施工技术受到人们的关注。鉴于此,本文以某建筑工程项目为背景,具体探讨弦支穹顶结构施工关键技术,针对弦支穹顶结构的施工张拉工序和杆件安装的变形控制问题展开分析,通过本文的研究为同类型结构的施工建设与研究提供些许参考和借鉴。

The suspend-dome is a new type of pre-stressed large-span space building structure,which is widely used in stadiums,terminal buildings and other large public buildings due to its reasonable stress,economic and aesthetic advantages.With the large-scale use of suspend-dome structure,its structural form is constantly improving,which virtually increases the difficulty of construction on site.How to ensure its smooth construction is a hot research topic,and related construction technology has attracted people’s attention.In view of this,this paper takes a construction project as the background,specifically discusses key technology of construction of suspend-dome structure,and carries out analysis on construction tension procedure of suspend-dome structure and deformation control of bar installation.Through this research,it can provide some reference and reference for construction and research of similar structures.
