The dry coal shed space frame structure is a large warehouse for storing coal in thermal power plants. The space frame structure of the dry coal shed requires a large span and high headroom to meet storage and operation space.
The development of the spherical space frame structure of the dry coal shed has a history of 20 years.The structural forms used mainly include a plane rigid frame, a plane truss, a plane arch and a cylindrical reticulated shell structure. According to the comparison of the technical and economic indicators of the built dry coal shed structure, the cylindrical reticulated shell has obvious advantages, and it has become the main structural form of the dry coal shed structure. Generally speaking, the main function of the dry coal shed spherical frame is to cover the coal yard to prevent the coal from being drenched when it rains and polluting the environment when it is windy. It is an energy-saving and environmental protection project. The architectural function of the dry coal shed is mainly a large storage warehouse. Therefore, it must have a certain storage and work space, that is, the structure must meet certain clearance requirements, and the cross-sectional shape of its effective space is trapezoidal, and the envelope of the work space is close to an arc.
The length and width of the dry coal shed frame structure are determined according to the requirements of the installed capacity, and the height of the structure is determined by the operation requirements of coal stacking and bucket turbines. Therefore, the characteristics of the dry coal shed structure are the large span, high height, and wide coverage area. The frame structure is adopted to reduce the roof load-bearing capacity. Generally speaking, 40-70 kilograms of steel is used per square meter of projected area. With the development of social power industry, the spherical frame of dry coal shed has been extensively constructed and researched. Due to environmental protection requirements and strict control of construction land, the way of coal piles must be replaced by closed storage methods, so the construction of dry coal sheds has developed vigorously in the society in recent years.
