The dry coal shed space frame is a small, medium and large warehouse for storing coal in power plants. Dry coal shed space frame construction requires large spans and high static voids, taking into account storage and working space.
The development trend of dry coal shed space frame structure has a history of more than twenty years, and the important structural methods used are plan design rigid frame, plan design row frame structure, plan design arch and whole face mesh shell structure. According to the comparison of the specialized economic indexes of the space frame structure of the dry coal shed which was completed long ago, the whole face mesh shell has obvious advantages, and now it has become an important structural form of the space frame structure of the dry coal shed.
Generally speaking, the important role of dry coal shed space frame construction is on the roof of the coal yard to prevent the coal from being drenched when it rains and air pollution when there is wind, which is an energy-saving and environmentally friendly mechanical engineering project. The role of the housing construction of the space frame of the social dry coal shed is mainly a storage depot of small, medium and large sizes. Therefore, it has a certain storage and operation space as far as possible, that is, the structure as far as possible to take into account a certain amount of static air requirements, and its effective use of the space of the cross-section molded in the shape of an arc, the envelope of the operating space close to the arc.
The length and total width of the space frame processing structure of the dry coal shed are established according to the necessity of power generation, while the height of the structure is established by the operational requirements of the coal pile and the bucket wheel. Therefore, the dry coal shed space frame structure is characterized by a large span, high height, and covers a wide area, the use of space frame structure, so that the flat roof bearing interaction force is reduced, generally speaking, each square meter of projected area with stainless steel plate 40-70kg.
With the trend of development in China’s electric power installation work, the dry coal shed space frame has been widely used in infrastructure projects and scientific research. Due to the requirements of ecological environment protection and strict control of land resources, the bulk pile of coal has been replaced by the closed storage method as much as possible, and thus the infrastructure project of dry coal shed space frame has developed rapidly in China in recent years.
