Although the welded ball space frame cost is relatively high, but the overall stiffness and joint stiffness are better than the bolt ball space frame, the peak internal force of the rod is greatly increased, can be used for large-span structure, and can bear large joint load, hanging joint structure is easy to handle. According to the span and suspension of this project, the fully welded ball joint space frame is selected.
The choice of structural steel material is a critical aspect of construction that affects the structural integrity, durability and cost-effectiveness of a building.
The round and simple warehouse and the coarse concentrate warehouse all belong to the steel silo structure.
As a kind of space structure, the space frame structure is favored by people for its high-efficiency mechanical performance, simple construction and production, and flexible and diverse shapes.
This project is a dry -election project for the company's iron ore. The project mainly includes two factory buildings, two independent storage warehouses, transport stations, and twelve tape machinery corridors. The factory buildings are dry elections and rollers, and the storage warehouses include cylindrical warehouses and crude ore warehouses.
The steel structure project of the hall is divided into two parts, namely, the steel structure roof truss of 600 square meters and the double-layer bolted ball space frame roof.
After careful study of the design drawings and repeated comparisons of several installation schemes, from the aspects of economy, safety and construction quality control, a full hall of scaffolding is used as the construction platform for installation and construction.
In view of metallurgical mine projects, more buildings in the construction construction are still used for concrete structures, and steel structures are usually applied to many aspects such as maintenance platforms, support, brackets, and large span covers.
This project has a large amount of steel structure and space frame works, and accordingly, there is a large amount of workload of pre-buried parts in the construction of main structure.
Large span steel structures can also be used in industrial buildings, such as the general assembly workshop of an aircraft manufacturing plant. The large span steel structures mainly work under self-weight loads. The main contradiction is to reduce the weight of the structure itself, so it is most suitable to use large-span steel structures. steel structure.
The dynamic characteristics of the structure of the large span roof structure are obviously different from the dynamic characteristics of general multi-layer / high-rise structure. If artificial analysis is performed in the process of structure analysis, the upper large span roof and the lower multi-layer support structure are performed separately, and it will often lead to a large error in the analysis of the two parts of the structure.
When the space frame is under construction, there are two steps to pay special attention to, which is to ensure safety, but also to ensure that the top of the space frame is conducive to the building, durable, with long life conditions.
