The main materials of light steel keel ceiling mainly include U-shaped skeleton and T-shaped skeleton. There are two types according to the load: the main parts are large, medium and small keels, and the accessories have hanging parts, connecting pieces and hanging pieces. . Before construction, it is necessary to select suitable keels, fittings and cover panels according to the design requirements to ensure that the variety, specifications and quality of the materials meet the design requirements.
Before construction, you should be familiar with the construction drawing and design instructions. According to the design requirements, the net height of the room, the pipe equipment in the ceiling and the height of the bracket shall be checked and handed over. Accept and accept the pipelines in the ceiling, equipment installation and pipeline pressure test. The embedded parts in the ceiling project, the steel bar and the steel bar shall be rust-proofed.
The construction process of light steel keel ceiling mainly has the following steps: ceiling elevation horizontal line → keel sub-line → installation of hydroelectric pipeline and commissioning → installation of main keel → installation of secondary keel → installation of cover panel → installation of beading.
There are several problems to be paid attention to during the construction process: the ceiling is not flat. The main reason is that the flattening of the boom is not serious when installing the big keel. The degree of tightness of each lifting point should be checked. The layout structure of the light steel skeleton is unreasonable, leaving holes and lamps. When the vents are installed, the corresponding nodes shall be installed to set the keel and connecting parts; the light steel frame shall not be fastened and shall be hung on the main structure. The internal pipelines and equipment parts of the ceiling shall not be hung on the light steel skeleton; the gap between the cover panels is not straight. During the construction process, pay attention to the specifications of the plate, and pull the wire to find the positive; the pressure seam and the pressure edge are not tight and straight.
During the construction process, it is also necessary to protect the various pipelines in the ceiling when installing the light steel skeleton and the cover panel. It cannot be fixed on the ventilation ducts and other equipment parts. The materials such as the light steel skeleton are guaranteed to be free from deformation and rust. The installed light steel frame shall not be stepped on by the person, and the cover panel shall be carried out after the completion of the pipeline and moisturizing process in the shed.
