Description

Plate light steel keel special-shaped ceiling structure

technical field

The invention relates to a plate-type light steel keel special-shaped suspended ceiling structure.

Background technique

The traditional light steel keel gypsum board special-shaped ceiling structure includes a ceiling foundation structure. The ceiling foundation structure includes two parts: a plane ceiling foundation structure and a special-shaped ceiling foundation structure. As well as the middle modeling facade, the surface of the light steel dragon skeleton at the bottom is covered with plasterboard, and special-shaped moldings are installed at the bottom of the modeling facade, and the paper-faced plasterboard and the special-shaped moldings are docked. After caulking putty and strapping to treat the joints, apply plaster putty on the surface, and finally paint with latex paint to complete. According to the different materials used, the above-mentioned basic structure of the suspended ceiling mainly has the following forms:

1. Special-shaped ceiling with wooden keel foundation structure;

The special-shaped ceiling with wooden keel base structure is made of all wood materials, and the planar structure also uses wooden keel, which is called wooden keel ceiling. The basic structure of the suspended ceiling is made of all wooden materials, and the surface is covered with gypsum boards to complete the construction of the suspended ceiling. The characteristics are: traditional craftsmanship, a long history, and strong adaptability to the construction of special-shaped ceilings. In today's decoration construction, wooden keel ceiling construction consumes a lot of precious wood resources due to the use of wood, and it is difficult to meet the fire protection requirements. repeat.

2. Special-shaped ceiling with all-light steel keel foundation structure

All-light steel keel basic structure special-shaped ceiling uses light steel keel main keel, auxiliary keel and traditional light steel keel related accessories, hand-processed light steel keel end shape, does not use wooden materials and wooden boards, directly connects light steel main and auxiliary keels , the installation of the ceiling foundation structure is completed. Then, the surface of the basic structure is covered with plasterboard, and after the joints of the suspended ceiling gypsum board are treated with caulking putty and bandages, the surface is plastered with putty and painted with latex paint to finally complete the special-shaped ceiling. The characteristics are: no wooden materials are used as the basic structure, a large amount of precious wood resources are saved, and the fire protection level is high. However, light steel keels are all used as the basic structure, and light steel keels need to be processed on site to connect light steel keels. cause the following problems:

1) Due to the limitation of the cross-sectional shape of the light steel keel, it is extremely difficult to process and connect the light steel keel, which consumes a lot of man-hours. It is the construction process with the lowest labor efficiency in the special-shaped ceiling construction process.

2) They are all pieced together on site, especially small-sized shapes, which result in time-consuming and labor-intensive construction of the foundation structure of special-shaped ceilings and surface gypsum board cladding (including the production of small shapes such as equipment inspection ports) in the early stage; It is laborious, and it is difficult to guarantee the construction quality of special-shaped ceiling decoration.

3) The ceiling construction is basically formed by processing conventional raw materials on site, and then assembled. The construction site is both a processing plant and an installation site. Not only is the scene extremely chaotic and noisy, but also a large amount of ceiling construction waste is generated. It not only increases the cost of transportation and garbage disposal, but also destroys the human living environment, occupies and pollutes precious land resources.

4) Without a fixed connection method and related connectors, the basic structure often cannot guarantee accurate shape requirements, stability and firmness. Furthermore, it is difficult to set the foundation positioning point for the construction of the foundation structure of the all-light steel keel special-shaped ceiling, and the construction is extremely difficult. However, decorative items with high fire rating requirements have to be used. Moreover, the construction of this process is very random, there is no unified acceptance standard, and it is impossible to accurately quantify the material cost and labor cost.

In view of this, the present invention is proposed.
