[0002] With the rapid development of industrialization, the demand for the construction of industrial plants is growing. Industrial plants need to meet the requirements of high efficiency, durability, environmental protection and reusability to adapt to the rapidly changing production needs and market environment. The traditional on-site pouring construction method has problems such as long construction period, difficult quality assurance, and waste of resources. It can no longer meet the requirements of rapid, efficient and environmental protection for the construction of modern industrial plants. Prefabricated and assembled building technology is a construction technology that prefabricates part or all of the components of a building in a factory and then transports them to the construction site for assembly and connection. Prefabricated and assembled building technology has the advantages of fast construction speed, controllable quality, energy saving and environmental protection, and is widely used in industrial plants, residential buildings, public buildings and other fields; however, in actual application, the commonly used prefabricated composite panels are not suitable for large-area and large-span industrial plants due to their size and weight. Multiple prefabricated composite panels need to be poured with concrete for the second time to form a post-cast slab belt. In actual construction, the template construction of the post-cast slab belt is cumbersome and labor-intensive; therefore, a prefabricated and assembled structure for industrial plants with high strength and easy construction should be provided.
