Gypsum board has the characteristics of light weight, sound insulation, heat insulation, strong processing performance and simple construction method. Gypsum board is often used in home decoration, so what is the construction process of gypsum board ceiling? Please read the detailed introduction by Rilong editor.

1. Construction process
Elevated horizontal line of elastic ceiling → draw keel binning line → install pipeline facilities → install main Keel boom → install main keel → install secondary keel → install gypsum board → apply anti-rust paint → install beading → install gypsum lines
2. Elevation level of elastic ceiling
According to For the floor elevation horizontal line, use the vertical vector of feet to reach the ceiling design elevation, and then pop up the ceiling elevation horizontal line along the walls and around the columns.
3. Draw the keel binning line
Arrange the main and secondary keel spacing according to the design requirements, and draw the keel binning line on the elastic horizontal line of the ceiling.
4. Install the main keel boom
After setting the ceiling elevation level and keel position line, determine the elevation of the lower end of the boom, according to the main keel position and hanging spacing , use welding connection to fix one end of the boom without bolt thread and the floor slab's embedded steel bars (expansion bolts can be used when the steel bars are not embedded), and apply anti-rust paint on the welded parts.
5. Installation of light steel keel main keel
1. Equipped with boom nut.
2. Install the hanging parts on the main keel.
3. Assemble the main keel of the hanging parts, insert the hanging parts into the corresponding boom bolts according to the position of the binning line, and tighten the nuts.
4. Install the connecting parts at the joints of the main keels, and adjust the elevation, camber and straightness by pulling wires.
5. Install the main keel attached to the hole, and set the connection card firmware according to the corresponding node structure in the atlas.
6. Nail the side keel and fix it with nails. When there is no requirement in the design, the nail spacing is 1000_.

6. Install the main keel
Bend the end of the embedded steel bar into a ring-shaped hook and thread it through No. 8 galvanized iron Wire or ф6 or ф8 bolts are used to fix the main keel. When there are no pre-embedded steel bars, expansion bolts can be used and the design elevation must be guaranteed. The arching of the suspended ceiling shall be based on the design requirements. When there are no design requirements, it is generally 1/200 to 1/300 of the room span.
7. Install the sub keel
1. Press the sprung sub keel line and snap the sub keel hanging parts.
2. Hang the sub keel: According to the spacing between the sub keels specified in the design, hang the sub keel on the main keel through the hanging parts. When there is no design requirement, the general spacing is 500_~600_.
3. When the length of the sub keels needs to be extended by multiple keels, use sub keel connectors to connect the sub keels while hanging them, straighten and fix them.
8. Installation of gypsum board
1. The following preparations should be made before installation
All keels have been adjusted; heavy lamps, fans and other equipment The suspension rods have been arranged; the ventilation, water and electricity pipes in the suspended ceiling and the pedestrian or safety passages in the suspended ceiling should be installed, and the fire protection pipelines have been installed and debugged; the light troughs, diagonal braces, scissor braces, etc. in the suspended ceiling should be installed according to the The project situation is appropriately arranged.
2. Laying direction
The gypsum boards are installed in staggered seams starting from one end of the ceiling, arranged piece by piece, and the remaining amount is placed at the end for installation. The long side of the gypsum board is aligned with the sub-keel. Cross state (parallel to the main keel). The overlap width of two adjacent gypsum boards on the same primary keel should be basically equal, and a gap of about 3mm should be reserved between the boards during installation.

3. Board installation and connection fixation
Gypsum board must be installed in a stress-free state to prevent Forced into position. During installation, use wooden supports for temporary support, and press the board and frame tightly. The supports can only be removed after the screws are fixed. When installing the fixing plate, it should be fixed from the middle to the four sides of the plate. Do not work at multiple points at the same time. After fixing one piece, install and fix the other one in sequence.
(1) The distance between the fixed paper surface and the sub-keel
To fix the paper-surface gypsum board, flat-head self-tapping screws should be used according to the different keels. The distance between the self-tapping screws and the sub-keel edge should not be smaller than 3_,
(2) The distance from the edge of the board
The edge of the panel encapsulated is 10_~15_, and the edge of the cut board is 15_~20_.
The distance between self-tapping screws is preferably 150_~170_, and the screws should be perpendicular to the board surface. The nut should be slightly buried about 0.5mm into the board surface so as not to damage the paper surface. The exposed self-tapping screw ends should be painted with anti-rust paint.
(3) Installation of double-layer gypsum board
When installing double-layer gypsum board, the joints of the surface board and the base board should be staggered and not on the same keel. Top seams.
4. Treatment of gypsum board interfaces
A cross brace keel must be installed at the board interface, and the board at the interface is not allowed to be "suspended".
5. Joint treatment
(1) Preparation of single-component caulking gypsum putty
The container used for preparation must be clean. According to the specified proportion, first pour clean water into the container, then slowly add caulking gypsum powder into the water, let it swell for 5 minutes, and then use a clean stirring rod to stir it into a thick slurry without caking. Do not add gypsum powder to the prepared slurry to avoid clumping. The generally applicable construction time is 45 minutes. If the time is exceeded, it will start to solidify and cannot be used.
(2) Board edge treatment
There is no need to process the longitudinal edge of the board covered with tissue paper. The cut board edge should be processed as follows before caulking: Before the board is installed, Gently chamfer the upper edge of the front cardboard edge. After the board is fixed, use a knife to separate the upper layer of tissue paper on the chamfered edge, and tear off the tissue paper. Be careful not to expose the gypsum core. This part The lower layer of tissue paper is still left on.
(3) Caulking process
Use a small scraper to embed the caulking putty evenly and fully into the gaps at the lower part of the board, so that the putty squeezes out of the edge of the back panel to form a convex The edge of the putty that comes out will make the edge of the board and the caulking putty bite more firmly. After the putty is completely dry, use an electric or manual grinder and No. 2 emery cloth to smooth the caulking gypsum putty. After that, it can be decorated and constructed together with the entire plaster ceiling.
During decoration, we must strictly select decoration materials and strictly control every construction process.
