Designing Optimization And Engineering Application Of Steel Truss Corridor

In recent years, with China’s rapid development of the industry, factories using motor transport material to ensure that large quantities of production continuity, and the high cost of transportation. Continuous conveying belt, tube belt not only can ensure the sufficient supply of materials, and low cost, can realize automatic control. This prompted the carrying belt, tube and other mechanical equipment steel structure traverse in the metallurgical, mining, coal, power, cement, ports and other enterprise applications.And reinforced concrete frame supported brick structure of the corridor than the body, steel structure truss corridor has the advantages of light weight, large span, less land occupation, high degree of industrialization, beautiful appearance, good anti-seismic performance, short construction period and a series of advantages. Corridor economic span in general can reach about30m, when the belt climbing height increases, economic span can reach more than50m, span is increased to a plane arrangement provides greater flexibility, the new gallery below can be built in small conformation, buildings or traffic site.This paper taking Jigang grate-kiln project finished7belt corridor as an example, the steel structure truss type single belt corridor study. First discusses the overall structure of the overall composition, a force transmission route, unit division and span determination; secondly to form a two main truss, frame structure, force analysis, calculation, in the component selection and layout optimization of truss; and further, support nodes and connecting truss, frame the support is calculated; at the end of the corridor and corridor closed form in the harsh environment of the anti-corrosion and other brief analysis. Through the gallery design of every aspect of the research and analysis, summarized the corresponding economic practice.This article on the belt corridor study is calculated by hand and computer aided design of load combination method, through the calculation of internal forces of software modeling, analysis, comparison and selection of optimal scheme for the entire corridor, reasonable stress, safe, convenient construction and material saving.This paper from the point of design, through the analysis of steel structural traverse member:stress is relatively clear, simple calculation, steel truss Gallery body as main skeleton, landing support as the main supporting structure. Truss and frame of the two independent structures using computer software easy modeling, load is relatively simple, most members are main force characteristics of axial force, can make full use of steel strength. In addition, steel structure traverse construction convenient, fast, steel structure truss, support are available in the factory into a batch processing, the scene is only required to be processed lifting component of stitching, thus greatly improving the construction efficiency, brought good economic benefits and social and environmental benefits.
