Difficulties in expanding data structures
1. The components are large in size and heavy in weight.
As the main load-bearing component of the roof structure, the truss column has a maximum section of 25m×20m, a height of 67m and a maximum weight of 500 tons. However, the height of the main truss is 12m, the maximum span of the double-span truss is145.577+12.788m, and the maximum span of the non-span truss is 102.95438+0m. Truss columns and main trusses are bulky and heavy.
2. Nodes are complex
Because all the members of this project are box-section members, there is a phenomenon that multiple members intersect in space, whether between the main structures or between the primary and secondary structures. In addition, the substructure is complex and changeable, and the regularity is less, which leads to the complexity of the node structure of the main structure, the variety of node types, and the high accuracy of fabrication and installation.
3. The construction period is tight
The engineering quantity is large, but the installation period is quite short. The project started on February 24, 2003, with a capacity of 65,438+,and was completed before the end of 2007 and by the end of March 2008. The construction period is tight, overlapping with civil works, and the plane site is tense.
4, the welding quantity is large
The site connection of this project is divided into multi-section welding and hoisting, and the site weld length is long. In addition, thick plate welding, high strength steel welding, steel casting welding, etc. Most of them are involved, which leads to considerable workload, high difficulty and more overhead welding.
5, winter rainy season construction
The hoisting time of the main structure of this project needs to span winter and Spring Festival, and it is difficult to construct in winter and rainy season.
