The screws must be perpendicular to the ceiling and fixed firmly, and the six screws should be parallel.
2. Punch holes in the ceiling at six points with an electric hammer (do not affect the installation of electrical appliances).
Measure the distance from the top to the corner line, intercept the screw that is 8- 10cm shorter than the actual distance, while screwing a nut and an expansion screw (the screw is exposed by about 3 mm), and screw the nut on the other side, put on the main keel hanger and screw a nut to fix it.
3. Knock the joint between the expansion screw and the screw into the hole, connect the large ceiling with the screw with a diameter of 6mm, screw the nut into the screw, then insert the large hanger, screw the nut, and so on.
Second, the keel installation is very important. The keel is installed with a gusset plate, and the electrical installation will be much smoother.
1. Compare the sizes of each hanger, clamp the main keel on the hanger, cut out the required size, and keep the main keel parallel after clamping.
2. Put the triangular hanger into the triangular keel and fix it on the main keel in turn. Before fixing triangular keels, adjust the distance between keels to 300mm. ..
Arrange the air outlet pipe of the range hood in front of the pinch plate. If you don't have a range hood, you don't need it
3. The specific method is: subtract 5mm from the installation length, and then cut off the required triangular keel.
After the triangular hanger is inserted into the triangular keel, the triangular hanger is stuck on the main keel.
Pay attention to the same triangular keel hanger stuck on the main keel, and the clamping direction should be opposite, so that it will not swing when the installation continues.
Iii. Install the gusset plate 1. First, insert the connector into the fixed triangular keel, cut the required length and insert it into the other end of the connector.
2. Install the gusset.
First, lift the film on the four sides of the pinch plate and install it in the direction of the arrow on the film.
The installation of the first row of gusset plates is generally cut with a utility knife, and attention should be paid to beauty and symmetry, with the cutting opening facing the wall.
3. Fix the cut gusset plate on the triangular keel, put the cutting surface on the edge strip, pull out the corners of the edge strip and fix the gusset plate. Take this as an example to install the first row of gusset plates.
4. Control the spacing of gusset plates in the first row, so that the spacing of gusset plates is 0, the four corners are cruciform, and the height of gusset plates should be consistent.
The installation quality of the first gusset plate directly determines the installation quality of the rear gusset plate.
4. Install electrical appliances 1. Insert one side of the clamp spring into the round hole on the box body mounting clamp spring, and insert the machine screw into the round hole on the electrical box and lock it.
Put the box with clamp spring on the keel, press the open slots of the four clamp springs in turn, aim at the triangular keel, and lock the electrical box firmly on the triangular keel.
2. Next, open the junction box, connect it according to the corresponding function according to the wiring label, then install a switch to test whether it is electrified, and cover the junction box after it is electrified.
3. Finally, check whether the gusset plate is flat and whether the electrical appliances can be used normally. The installation of the integrated ceiling is basically completed here.
