[0002] As an indoor top decoration material, the ceiling can be connected to the top plate through a hanging assembly to cover the main structure, thereby achieving multiple functions such as beautifying the environment, heat preservation and heat insulation. This structure has been widely used in shopping malls, office buildings, residences and other places. At present, when the decoration industry installs the ceiling structure, it usually uses expansion bolts to fix the hanger on the top plate, and then uses self-tapping screws to fix the keel frame to the lower end of the hanger. Finally, the integrated board (such as gypsum board) is nailed to the bottom surface of the keel frame. This method is not only cumbersome, but also difficult to remove the components separately during daily maintenance, which is easy to cause secondary losses. In addition, if the keel is tilted or uneven during installation, it is more troublesome to adjust. Therefore, a prefabricated keel overlap structure is provided to solve the above problems.
