国外某机场新航站楼屋面主承重构件由双向弯曲的大跨度空间三角拱桁架组成,构件异形、倾斜、重量较大,吊装施工难度极大.以空间三角拱桁架为例,在海外工程不断探索实践,适应当地不同规范要求,从吊装设备选用、寻找重心、受力计算、过程分析等方面介绍了吊装施工技术,探索出了一条安全、高效、快捷、精细化的吊装专业化管控道路.
The main load-bearing component of the new terminal building in a foreign airport is composed of a large-span triangular arch truss which is bent in two directions. The components are irregular, inclined and heavy, which makes it extremely difficult to hoist the building. Taking the spatial triangular arch truss as an example, Practice, adapt to the requirements of different local regulations, from the selection of hoisting equipment, to find the center of gravity, force calculation, process analysis and other aspects of the lifting construction technology, to explore a safe, efficient, fast and sophisticated hoisting specialized management and control roads.
