摘要
上海新国际博览中心屋盖结构形式为大跨钢结构空间桁架 ,采用空中有支架拼装方法施工。在大跨钢结构施工中 ,施工方案的选择至关重要 ,得当与否直接影响到工程造价和结构安全。在此 ,介绍了该工程施工中采用的拼装单元划分、支撑点设置和支架卸落等方面的施工方法 ,给出了选用这些方法的理论依据。施工中的实测数据与理论分析吻合良好 ,证明采用的方法是正确的。
The structural form of roof used in New Shanghai International Fair Center is large span steel space truss The construction method adopted in this project is conjoining in site with trestle It is very important to select a suitable construction method,which will be directly connected to the cost of construction and the structural safety The methods,eg dividing installation units,setting supporting points and unloading the trestle are introduced and the theory bases of these methods are given as well The data measured in the process of construction are closely consistent with that expected
