[0002] Nowadays, with the increasing improvement of people's material life, the high-quality requirements for decorative effects are also increasing. Most metal plate ceilings will use double keels when there is a large gap between the ceiling panels during the installation process. The joints of the entire panel are uniform and the shape is relatively simple. Not only is the installation process cumbersome, adjustment after welding is inconvenient, and the cost is high, but the labor intensity of workers is high and on-site welding is required, which poses a safety hazard and increases the risks encountered by workers during the construction process.

[0003] At present, metal plate ceilings at home and abroad are installed and constructed with double keels. This method has complicated installation procedures, inconvenient adjustment after welding, high cost, and high labor intensity for workers. Due to the complicated fixing method, it not only delays the construction period, but also increases the risks encountered by workers during the construction process. Utility Model Content

The connection conversion device is formed by a combination of conversion parts such as threaded parts, single-hole parts, three-hole parts and five-hole parts. One end of the connection conversion device is connected to the ceiling panel through a J-shaped reinforcing side rib, and the other end is fixed to the embedded plate or ceiling keel of the main body of the building structure through a ceiling adapter. The connection conversion device includes two adjustment conversion steel plates and two threaded adjustment rods. Four threaded adjustment rods run through the corners of the adjustment conversion steel plate, and the middle part is connected to the adjustment conversion steel plate by running through one threaded adjustment rod, and then fixed to the ceiling adapter. The height of different building ceiling panels can be adapted by selecting ceiling adapters of appropriate length; the requirements of various special-shaped folded ceilings can be met by adjusting the bottom angle of the J-shaped reinforcing ribs of the panel; three-dimensional flexible adjustment can be achieved by connecting the conversion device, which is convenient for installation and construction.
