This type of frame mostly adopts a composite system of \"grid frame + steel column\". Taking a coal storage shed with a span of 86 meters as an example, its space frame is composed of a triangular pyramid grid composed of upper chords, lower chords, and web bars, and cooperates with 4 lattice steel columns to form an overall force system, which can withstand the roof live load of 0.7kN\/\u33a1 and the basic wind pressure of 0.65kN\/\u33a1.\u200bIn terms of structural characteristics, the frame has three major advantages: first, high material utilization rate, the load is transferred to the surrounding supports through the spatial grid, and the steel consumption is reduced by 15%-20% compared with the portal frame; second, strong adaptability, the plane size can be flexibly adjusted according to the coal storage volume, and a modular design with a span of 50-120 meters and a length of 100-300 meters has been achieved; third, convenient maintenance, the connection between the rod and the bolt ball is convenient for the replacement of a single component, greatly reducing the later maintenance cost. \u200bDuring the construction, two aspects need to be focused on: on the one hand, the node processing accuracy, the angle deviation of the bolt ball screw hole needs to be controlled within \u00b130\u2032 to ensure the angle fit after the rod is installed; on the other hand, the overall lifting stability, when using the \"partition synchronous lifting\" process, the hydraulic synchronous control system needs to be used to ensure that the height difference of each lifting point does not exceed 50mm. In addition, the surface of the frame will be sandblasted and rusted (Sa2.5 grade) and fluorocarbon paint will be applied to form a long-term anti-corrosion protective layer to meet the service life requirements of more than 15 years in the coal storage environment.\u200bThe application of this space frame not only solves the structural safety problem of large-scale coal storage facilities, but also provides a stable carrier for the installation of subsequent roof systems and ventilation equipment. It is the key technical support for achieving closed coal storage. \u200b"}
