Characteristics of space frame coal shed

       Generally speaking, the main function of space frame coal shed structure is to cover the coal yard to prevent the coal from getting wet in the rain and polluting the environment in the wind. It is an energy-saving and environmental protection project. The architectural function of the space frame coal shed is mainly a large coal storage bin. Therefore, a certain amount of storage and working space is required, i.e., the structure shall meet certain headroom requirements, and the cross-sectional shape of its effective use space is trapezoidal, and the envelope of the working space is close to a circular arc.

　　The length and width of the space frame coal shed are determined according to the needs of the installed capacity, and its structural height is determined by the pile of coal and bucket wheel to determine the operating requirements of the machine. Therefore, the net frame coal shed structure has a large span, high height, wide coverage of the characteristics of the net frame coal shed development has a history of 20 years. The main structural forms used are planar rigid frame, planar truss and planar truss arch and column surface space shell structure. Through the comparison of the technical and economic indexes of the constructed dry coal shed structure, it is proposed that the column face space shell structure has now become the main structural form of the dry coal shed structure.

　　Space frame coal shed installation steps are: with scaffolding erection and installation of flat – high altitude bulk three-span round arch space frame – trial adjustment of a fixed support – high altitude small unit lifting method of installation – space frame level installation – paint spraying.

　　The components and nodes of the space frame coal shed are relatively single and stereotyped, so they can be mass-produced and processed in the factory. This not only ensures the quality of processing, but also shortens the production time, which is obviously superior to the processing and production of other types of space structures. The use of materials is economical and large spans can be spanned with less material. Space truss structure is a three-dimensional stress structure. The spatially intersecting members support each other, the stressed members are organically combined with the support system, and the members mainly bear the axial force. The material is economical and the stiffness is large, which is suitable for the case of large span.
