What are the precautions for wooden keel ceiling?

Construction method of wooden keel plasterboard ceiling: 1. Construction preparation Before the construction of wooden keel plasterboard ceiling, the main parts and accessories of skeleton and mask should be prepared first; After the keel is welded firmly, paint on its surface; Ceiling should be carried out after wall decoration and before ground decoration; Prepare corresponding machines, materials and manpower. Second, the construction technology (process) 1, gypsum board ceiling skeleton installation: 1), select the corresponding accessories, materials and tools, and determine the positions of the keel and lifting points and the ceiling elevation according to the design requirements on the basis of the structure; Clear vertical lines pop up on the walls and cylinders. Note: Lifting points should be added at the end of main keel or extension line, and the position of elevation line should be accurate. 2) After the lifting point and elevation line are defective, fix the telescopic boom at the lifting point, and connect the keel with the boom. The length of the threaded part at the end of the boom should be greater than or equal to 30mm, so as to have a larger adjustment space. All suspenders shall be neat and consistent, and conform to the requirements of surface-mounted installation. 3) When installing hanger bars, the spacing between hanger bars of wooden arcade is less than 1m, and the spacing between hanger bars of microporous aluminum plate and gypsum board is less than or equal to 1.2m 4) After completing the above steps, the keel can be installed. First, connect and fix the main keel with the suspender in primary and secondary order, and then adjust the elevation of the main keel according to the elevation line to make it on the same horizontal plane. Note: Generally, the position of the primary and secondary keels should be elastic at the bottom of the main keel according to the size of the decorative board and fixed with pendants, so that it can be fixed firmly and will not be loose. 5), in order to prevent the main keel to one side, small keel should be perpendicular to the main keel installation. The reinforcement of reserved holes and chandeliers should meet the design requirements, otherwise it will be very troublesome to install chandeliers in the later stage. 2. Installation of the ceiling cover panel: Before installing the ceiling cover panel, be sure to check whether the preparatory work before installation is completed and whether it meets the conditions for installing the ceiling cover panel. After all the conditions are met, pull the wires according to the installation requirements, and finally install. The cover panel shall not have cantilever phenomenon, and additional keel shall be added; Temporary. During construction, it should be erected or hung on the structural stress members, and it is forbidden to use the ceiling keel as the support point. 3. Installation of gypsum board: The installation method of gypsum board adopts screw installation method. The long side of the gypsum board crosses the secondary keel, so that the end edge falls in the center of the secondary keel. Gypsum boards should be staggered from one end of the ceiling, arranged one by one, and the rest should be installed at the end. Wooden keel plasterboard ceiling should be operated in strict accordance with each step. In the process of construction, we should keep in mind all kinds of precautions, pay attention to and check at any time. In order to create a perfect gypsum board ceiling, the construction technology of the whole wooden keel gypsum board ceiling can reach the best level.
