Description

Technical Field

[0001] The invention relates to the technical field of suspended ceilings, in particular to an assembled ceiling structure. Background Art

[0002] With the development of society, the construction industry is also developing better and better. After the construction of a house is completed, the residents can decorate the house before moving in to improve the living environment of the house. The ceiling is a kind of decoration on the top of the house. Simply put, it is the decoration of the ceiling. It can not only beautify the indoor environment, but also create a colorful artistic image of the indoor space. Its structure has various forms. For example, the Chinese patent "CN219825808U" announced "a ceiling edge trimming installation structure". Through the setting of the overlap part and the ceiling overlap part, it is convenient to assemble the ceiling edge trimming piece to the wall top overlap part, thereby improving the installation convenience of the installation structure; the ceiling edge trimming piece and the wall top overlap part are connected by the ceiling limiter to prevent the ceiling edge trimming piece from slipping relative to the wall top overlap part, thereby improving the installation stability of the ceiling board.

[0003] However, in this installation method, only the connection between the ceiling edge parts and the wall overlap parts is used, and it is necessary to install the wall or keel from the inside of the ceiling to fix the wall and the ceiling. The connection and installation between the ceiling panel and the keel still need to be installed with traditional wall nails in combination with T-shaped pieces or I-shaped pieces. The installation, removal or replacement of the ceiling panel and the keel is relatively troublesome, and it is necessary to drive wall nails and connectors in multiple places, which has high technical requirements for construction personnel and low construction efficiency. After installation, the connectors and wall nails are exposed, and the consistency with the ceiling decoration is poor, which affects the aesthetics. When the ceiling panel needs maintenance and replacement, the wall nails and connectors need to be pulled out, which is difficult to disassemble and is prone to high-altitude dangers. The stability of the ceiling panel and the overall connection is poor, and the plasticity of the overall disassembly and connection changes is poor. Therefore, it is necessary to propose a bottom surface plug-in assembled ceiling structure that improves the connection stability between the wall, keel and ceiling panel and facilitates the installation of the ceiling panel and keel to solve the above-mentioned problems.
