The ceiling is inseparable from each of our families during the renovation. Everyone pays attention to its quality when we decorate. Everyone knows that the keel is inseparable from the ceiling, but I don’t know how to do it because I don’t know about the decoration. So everyone knows what is the construction technology of the wooden keel ceiling? Today, Xiaobian will take a look at the construction process of the wooden keel ceiling and the construction points!
What is the construction technology of wooden keel ceiling?
1. Put the line, the first step: determine the elevation line, take the floor reference line as the starting point, and measure the height of the ceiling (plus the thickness of the board) on the training (column) surface according to the design requirements, and at this point Draw the standard line (as the lower line of the ceiling keel). It can be measured by a water level meter or a "water column method". Step 2: Determine the line in the shape: According to the design requirements, draw the specific position line of the shape on the top or the surface.
2, wood keel assembly, wooden keel should be assembled on the floor (ground) before lifting, the assembled area generally does not exceed 10 lining. The method of keel assembly often uses a bite-and-small-female fastening method. The specific method: slotting the keel, assembling the slot between the slot and the slot, applying glue in the slot and fixing with a nail.
3, installation of lifting points, installation of lifting points, hanging bolts commonly used expansion bolts, embedded parts, etc., lifting bars can be used for steel bars, angle steel or square wood, welding, binding, hooking, bolting between hanging points and hanging bars Or connect by screws or the like.
4, keel hoisting and fixing, use the wire to hang the assembled wooden keel straight above the elevation line, temporarily fix it, use the rod line or nylon thread to pull out several parallel lines and diagonal cross lines along the ceiling elevation line. Accurately move the keel slowly to the level of the elevation line and then attach it to the sling. In the same way, the cascading ceiling keel is fixed, and the upper and lower keels are connected.
5. The keel is leveled and arched. After the whole keel is connected, the diagonal cross line is pulled down on the bottom surface of the ceiling. Check the flatness of the ceiling. When the area is large, the arch can be arched. The height of the arch is about 1/200 of the room span. ~1/3000
6. Install the paper-reinforced gypsum board and use the self-tapping screws to nail the paper-reinforced stone board to the keel. When installing, note that the long side of the plasterboard must be perpendicular to the secondary keel, so that the end edge falls on the secondary keel. Central part. The gypsum board should be installed in a free state. When fixing, it should be fixed from the center to the four sides of the board, and a gap of 6 mm should be left between the gypsum board and the surface.
Main points of construction of wooden keel ceiling
1. The wooden keel must be dry, and the water content is below 12 degrees. The main materials such as white pine, red pine and Meisong are selected.
2. According to the design requirements, the elevation horizontal line, the shape of the raft, the position of the raft and the location of the puncturing point are popped up.
3, the size of the wooden keel is subject to the design requirements, the main keel: 5 cm × 5 cm, 4 cm × 5 cm, 5 cm × 7 cm. Secondary keel: 3 cm x 4.5 cm, 2.5 cm x 3.5 cm, 4 cm x 5 cm. Diagonal support: 2 cm x 3.5 cm, 3 cm x 4.5 cm. Scissor support: 2.5 cm x 2.5 cm, 3 cm x 3 cm.
4, the diagonal support, scissors support should be properly arranged according to the ceiling area, the arch size is 1/200 of the short span of the room, the purpose of arching is to balance the gravity of the facing to ensure that the ceiling does not protrude.
5. When the secondary keel and the main keel are fixed with nails, they should be nailed.
6. The step type (high and low drop) ceiling starts with a higher surface, and the high and low surfaces are first positioned and fixed.
The keel is very important when we carry out the ceiling, so it is very important to learn how to work. The above is what the small wooden keel ceiling construction process introduced for you today and the construction points are here. To learn more, please continue to pay attention to the decoration home.
