The method of PVC gusset ceiling

What is the method of PVC gusset ceiling:

Measure the length and width of the room, and determine the length of the gusset and the installation direction of the horizontal and vertical.

Reserve the line answering path for lighting, bath back, exhaust fan, etc.

Determine the height of the ceiling and find the horizontal line around it.

Edge keel according to the height edge.

Use the main and auxiliary keels to make the entire skeleton.

According to the determined horizontal and vertical direction of the PVC board, reserve a transverse edge, and fix the corners of the PVC with structural adhesive and self-tapping wire.

Start from the side with horizontal corners and fix them one by one, until the last piece (pay attention to lead out various lines at the predetermined position, do a good job of mounting brackets, or directly install the lamps and lanterns).

Cut the last corner with a wallpaper knife to remove the part that should be hidden in the gusset, and apply structural adhesive to install it in the predetermined position.

PVC gusset ceiling removal method:

First, use a utility knife to cut the area where the glass glue is bonded.

Insert the utility knife into the gap between the last and the penultimate piece, and gently move the utility knife up and down vigorously, and the PVC gusset will come loose after a while. At this time, we only need to push the movable PVC gusset to the left or right, and then the PVC gusset will be staggered with the installation position, and then we can remove the PVC gusset.

Generally, except for the last PVC gusset plate, which will not be self-tapping screws, other PVC gusset plates will be fixed with self-tapping screws. So the PVC gusset inside, we first need to use a screwdriver to remove the self-tapping screws, and then follow the method of the second step to disassemble it.

PVC gusset ceiling installation steps:

1. According to the design elevation, the line should be played on the wall around it, and the line should be clear, the position should be accurate, and the allowable deviation of its level should be 5mm.

2. Fix the side keel along the elevation line, the role of the side keel is the sealing of the edge of the ceiling, the common specification of the side keel is 25*25mm, its color should be the same as the PVC gusset, and the side keel is mostly fixed on the wall column with cement nails.

3. Determine the keel position line, because each PVC gusset is a formed veneer, generally can not be cut into blocks, in order to ensure the integrity of the ceiling finish and the reliability of installation, it is necessary to arrange the structural size of the ceiling skeleton according to the size of the aluminum gusset and the area size of the ceiling. The basic arrangement of the PVC gusset veneer is: the plate combination should be complete, and when the edge is left around, the surrounding edge should be symmetrical and even, and the arranged keel position line should be drawn on the top of the elevation line.

4. The spacing of the main keel hanging point should be selected according to the recommended series of design, and the middle part should be arched, and the height of the keel arch should not be less than 1 200 of the room span. After the installation of the main keel, the position and height should be corrected in time. To control the flattening of the keel, first of all, you should pull out the longitudinal and horizontal elevation control line, start from one end, and adjust the suspension height of the boom while installing.

After the large surface is flattened, adjust some single keels with curved warped edges until the smoothing meets the requirements.

5. The boom should be straight and have sufficient bearing capacity. When the boom needs to be lengthened, it must be lap welded firmly, and the weld must be uniform and full. For anti-rust treatment, the boom shall not exceed 300mm from the end of the main keel, otherwise the boom should be added to avoid the main keel falling, and the secondary keel (the same as the middle keel or small keel) should be installed close to the main keel.

6. Comprehensively correct the position and levelness of the main and secondary keels. The connectors should be installed in dislocation, and the installed ceiling skeleton should be firm and reliable, and the next step of construction can only be carried out after meeting the relevant specifications. 7. When installing the PVC gusset, the secondary bone should be straightened.

The gusset plate should be flat and not warped, and the flat error of the ceiling plane should not exceed 5mm.

1. Elastic line copy

You can start around the wall.

Eject the elevation line, and then fix the pressure line with cement nails at both ends of the wall, and play the line around the wall according to the standard height, which can be used as the standard line for roof installation.

2. Install the main beam.

When installing the main beam, it is necessary to fix the side keel with cement nails along the marked line, determine the position of the keel, and then install the keel. In addition, when installing the keel, pay attention to leaving the outlet of the lighting line.

3. Install the wooden keel.

When installing the wooden keel, the keel around the wall should be kept horizontal, and the ceiling spacing is 1200 to 1500mm, and the ceiling is 900mm to 1200mm.

4. PVC ceiling gusset installation.

The final step is the installation of the panels, before which the installed keel and plates are checked and can only be installed after they meet the requirements. The installation direction of PVC ceiling gusset is determined according to the length of its board, if its longitudinal material and horizontal material are similar, it can be installed in the direction of Shunguang.
