technical field

The utility model relates to the technical field of architectural decoration, in particular to a connecting piece, a keel and a skeleton structure thereof.

Background technique

Ceiling panels and wall panels are decorative panels often used in interior decoration projects. Both ceiling panels and wall panels have beautiful decorative effects and can create different decorative styles. For splicing and installation, it is also possible to design a pattern with a certain artistic conception and effect as a whole, and then splicing decorative plates according to the pattern effect to achieve the overall effect.

The installation and construction of decorative panels such as ceiling panels and wall panels is a very important link in the process of house interior decoration, and it is also a link with a large amount of on-site construction work. Therefore, not only splicing and installation are required, but also attention must be paid to installation and use safety. Avoid falling, while improving the efficiency of installation and construction. In the prior art, when splicing and installing decorative panels such as ceiling panels and wall panels, a keel frame is usually used to fix the decorative panels. The keel frame is provided with a mounting structure for fixing and installing the decorative panels. During the process of installing the decorative panels, First fix the keel frame on the wall (including the side wall for installing the wall panel and the top wall for installing the ceiling panel), and then fix the decorative plate through the installation structure, but this installation method has the following problems: On the one hand, the keel frame It is an integral structure with the installation structure. In the process of installing and fixing the decorative panels, it is necessary to take into account the positions of the keel frame and the installation structure at the same time, which makes the positioning of the keel frame difficult and seriously affects the construction efficiency. On the other hand, since the installation structure is an integrated type It is connected to the keel frame, so the keel frame must be arranged at each installation and fixing part, so that this part has an installation structure, which will not only lead to waste of the keel frame, but also increase the construction amount of the fixed keel frame; on the other hand, due to The installation structure cannot be adjusted relative to the keel frame, which makes the installation structure of the decorative panels insufficient in the parts that need to be reinforced and fixed, resulting in the installation and fixation of the decorative panels is not firm, and there is a risk of falling and hurting people during installation and use; in addition, The existing keel skeleton structure is complex, not only the production cost is high, but also the installation and use are troublesome, resulting in low construction efficiency.
