Woodworking ceiling process flow

The process flow of woodworking ceiling is as follows:

1, ceiling keel

Keels are an indispensable part of ceiling decoration, including wooden keels and light steel keels. When using the wooden keel, it should be noted that the wood must be dry and coated with fireproof and anticorrosive coatings. The decoration of Australia and China adopts light steel keel. Light steel keel is a decorative structural material made of relatively low density steel, which is characterized by light weight and large bearing capacity. The surface layer is galvanized, which is fireproof and durable.

2, gypsum board installation

The corner of decorative ceiling in Australia and China adopts "7-shaped" technology, which is seamless to prevent cracking. Cut a whole board into a "7" shape at the corner of the ceiling. This structure can ensure the stability of the suspended ceiling structure, and the decorative materials on its surface are not easy to crack, bulge and fall off.

The installation of gypsum board shall comply with the following provisions: when the nail method is used for installation, the distance between the screws and the board edge shall not be less than 15mm, and the screw spacing shall be 150 ~ 170 mm, which shall be evenly arranged and perpendicular to the board surface.

3. A gypsum board capable of decomposing formaldehyde

Wuhan Aohua Decoration now uses French Saint-Gobain gypsum board, which can decompose formaldehyde. Saint-Gobain, a global top 500 enterprise, was first used in Australia and China. Each gypsum board can decompose formaldehyde 1 1g, and the formaldehyde purification efficiency reaches 82.4% within 24 hours, which can effectively decompose formaldehyde for 20-40 years.

4, ceiling crack prevention treatment

Joints between ceiling plasterboards should be treated with plasterboard joint paper tape to prevent cracks.

5. Anti-rust treatment of nail cap

If the screw is not rustproof, the nut should be rustproof and painted.
