Description

Technical Field

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

[0002] Currently, the suspended ceiling industry follows traditional procedures to measure, cut, punch holes, rivet, and screw expansion screws for various types of keels to create various shapes.

[0003] When the construction is carried out according to the traditional construction method, the first step is for workers to climb up the ladder to install the top side keels and wall side keels. Workers use nail guns or impact drills to install anchors and install the side keels one by one to the building base;

[0004] The second step is to measure the width and height of the ceiling and cut the secondary keel according to the measured size. Due to the inevitable construction errors between the wall and the ceiling, the length of the keel to be cut must correspond to the measurement of each point, and the material is cut according to each value, which is time-consuming and labor-intensive.

[0005] The third step is to install the cut secondary keels, the spacing is usually 400mm, and each connection point needs to be drilled and then riveted. This step is labor-intensive and takes the longest time.

[0006] The fourth step is to install the surface gypsum board. (The present invention does not change the gypsum board installation technology)

[0007] The traditional keel system structure is as follows Figure 1 As shown, the top side keel and the wall side keel are fixedly connected to the top and the wall through internal expansion screws, the vertical sub-keel and the horizontal sub-keel are connected to the side keel by punching and riveting, and the end of the vertical sub-keel and the horizontal sub-keel close to each other is connected by F keel, and the connection method is also punching and riveting. When the traditional construction method is used for construction, this construction method has low work efficiency. Taking the home decoration of 120 square meters as an example, the standard ceiling project requires about 10 workers to complete;

[0008] Second, the quality is poor. Factors such as the inherent techniques, construction habits, and teachers of different workers vary from person to person, making it difficult to control the quality of the project.

[0009] Third, the cost is high. Labor costs continue to rise year by year. 70% of the cost of traditional construction methods is labor costs. The high cost also restricts the rapid development of the industry. Summary of the invention
