The space structure is formed by connecting a plurality of rod pieces through nodes according to a certain grid form. The basic units constituting the net rack are triangular pyramid, triangular prism, square, truncated quadrangular pyramid, etc., and these basic units can be combined into triangular, quadrangular, hexagonal, circular or any other shapes in plane shape. The roof has the advantages of space stress, light weight, high rigidity, good earthquake resistance and the like, and can be used as a roof of buildings such as gymnasiums, movie theaters, exhibition halls, waiting halls, stadium stand awnings, hangars, bidirectional large-column net frame structure space workshops and the like. The disadvantages are that the number of the rod pieces converged on the node is large, the manufacturing and the installation are more complex than the plane structure, and the grid structure is a high-order hyperstatic structure system. When the plate type net rack is analyzed, the nodes are generally assumed to be hinged, external load acts on the nodes according to the static equivalent principle, and calculation can be performed according to a space truss displacement method, namely a hinged rod system finite element method. Simplified calculations, such as cross-beam system differential analysis, plate simulation, etc., may also be used to perform internal force and displacement calculations. The nodes of the single-layer shell type net rack are generally assumed to be rigid connection and should be calculated according to a rigid connection rod system finite element method, and the double-layer shell type net rack can be calculated according to a hinged rod system finite element method. The single-layer and double-layer shell type net racks can also adopt a shell simulation method to simplify calculation, and large steel structure venues in China are increasing. In order to pursue the visual effect of the building, the newly-built steel structure building has more and more complex structure and more peculiar shape, and the integral (block) hoisting method is a common method for installing the net rack; according to the structural condition, the net rack structure is integrally hung outside, and an existing support is utilized or an auxiliary supporting jig frame is arranged for auxiliary installation during installation of the steel structure.
When utilizing the integral hoisting method to install the rack, need assemble the rack subaerial earlier, then utilize equipment hoist and mount the rack that splices, when the concatenation rack, ground occupies to assemble the place many, and the rack component is placed the place less.
