Pay-off and elastic line: according to the size, shape and position on the design drawing, draw the horizontal elevation line and the peripheral contour line on the wall, and pop up the keel grid line. Moisture-proof treatment: Waterproof treatment is needed in wet areas or near walls that are often in contact with water, such as external walls and toilets. Installation of base plate: the base plate is made of wood, and the wooden splint can be fixed on the wooden keel with air gun nails.
The construction process of woodworking ceiling is divided into several steps.
1, elastic line positioning
According to the floor elevation horizontal line, use a ruler to measure vertically to the ceiling design elevation, play the ceiling elevation horizontal line on the surrounding wall, and draw the step position line of the keel on the wall.
2, install the main keel boom
After playing the ceiling elevation horizontal line and the main keel position line, determine the elevation of the lower end of the boom. According to the position of the main keel and the spacing of the suspenders, one end of the suspenders without bolt wires is firmly connected with the floor with expansion screws.
3. Install the big keel
Install hanger nuts, prepare hanger signals in advance on the large keel, thread the assembled hanger into the corresponding hanger bolts according to the position of the step line, tighten the nuts, install the connectors and connect the large keel, and adjust the elevation and straightness by pulling wires. Finally, attach a big keel to the installation hole, cover and connect it, and nail the keel forward.
4. Install the middle keel
According to the played sub-keel step line, clamp the triangular hanger of the middle keel with the spacing of 400 ~ 450mm, and install the middle keel on the big keel through the hanger. When the length of the secondary keel needs to be extended more than once, the joint of the secondary keel should be connected while hanging the secondary keel, straightened and fixed.
5, sealed gypsum board
Under the installed dragon skeleton, according to the specifications of the cover panel, install a cover panel along the keel direction from the middle of the ceiling, and then extend from both sides.
6, detail processing
After the installation, carry out detailed treatment, adjust the position, and make the drawing seam uniform. Finally, install the layering and fix it with screws.
