[0031] Prefabricated buildings refer to buildings that are formed by prefabricating a large number of building components and accessories in factories, and then transporting these prefabricated components to the construction site for assembly and installation. In recent years, prefabricated buildings have been vigorously promoted due to their high construction efficiency, reliable construction quality and superior economic benefits. Among them, the walls surrounding various pipes in prefabricated buildings generally have inspection ports reserved for later inspection and maintenance.

[0032] Although the finished inspection structures currently on the market can meet the function of closing the inspection opening, most of them are exposed on the walls of prefabricated buildings, which makes it difficult for users to meet the requirements of design aesthetics. In addition, the finished inspection structures on the market and prefabricated buildings are often disassembled and assembled in a snap-on manner, which poses a risk of falling off or loosening during long-term use. Therefore, it is urgent to provide an inspection structure suitable for the walls of prefabricated buildings.

[0033] The present application relates to an inspection structure for the wall of an assembled building, comprising a connection frame 100, a rotating shaft assembly, and an inspection cover plate 300.
