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.
With the development of society and people's demand for building space, large span space steel structure will become one of the important structural forms of buildings. The majority of design and construction personnel should actively explore the form and construction technology of large span space steel structures in combination with the actual development of the industry, improve the efficiency and quality of construction, reduce construction risks, and provide the society with high-quality and efficient large span space steel structure building.
The role of steel structure in the field of construction is becoming more and more important, because the steel structure has a smaller weight and higher strength, and its plasticity and flexibility are stronger than other materials. Steel structures have also been applied to the space structure system, especially for large scale venues with large spans and high elevations.
The closed circular coal storage bunker is adopted, and all the coal stored is dry coal. Its main advantages are good sealing, 100% recovery rate without waste, and little environmental pollution. For coastal windy and rainy areas, it can reduce the flying of coal powder and the impact of sewage on the surrounding environment, and the appearance is beautiful and environmentally friendly.
The steel structure tube truss technology has been popular abroad for many years. While the Chinese construction industry is experiencing rapid development, it is gradually paying attention to the building roof system.
This project has a large volume of production and installation works, geometric dimensions, a variety of quantities, high installation accuracy requirements, transport and installation difficulties. Because all kinds of steel components need to be processed and made in the factory, and then transported to the construction site for installation through domestic transport, all kinds of components must be organised and planned in accordance with the requirements of the drawings, classification production, numbering, packing.
