The keel frame connection assembly includes a card-type keel and a ceiling keel. One end of the keel frame connection assembly is fixedly connected to the building wall and the other end is detachably connected to the card-type keel; the ceiling keel is card-connected to the card-type keel to form a keel frame connection assembly; and the gypsum board is screwed to the ceiling keel. The assembly of the matching structure of the application is relatively simple, and it is easy to connect the gypsum board screws to the ceiling keel, which can improve the overall decoration efficiency.

[0004] Although the above patent makes it easy to connect the gypsum board screws to the ceiling keel, which can improve the overall decoration efficiency, after the installation of the upper main keel frame in the existing ceiling keel frame is completed, screws are needed to connect the connecting parts and the secondary keel frame with the ceiling board. During the installation process, the work is done at a high place and screws need to be used, which will increase the difficulty of installation, reduce efficiency, and make disassembly and assembly troublesome. Therefore, in response to the above problems, we propose a new type of easily detachable keel frame. Utility Model Content
