1. What is a PVC gusset ceiling
PVC gusset refers to the PVC gusset ceiling material, which is based on polyvinyl chloride resin and adds a certain amount of Anti-aging agent, modifier and other auxiliaries are made by mixing, calendering, vacuum forming and other processes.
The PVC gusset ceiling is especially suitable for the ceiling decoration of kitchen and bathroom. It is light in weight, moisture-proof, heat-insulating, non-flammable, non-vacuuming, easy to clean, paintable, easy to install and low price. Etc.
Second, the construction process of PVC gusset ceiling
1. According to the design elevation, the elastic line should be clear and accurate. Its horizontal allowable deviation is ±5mm.
2. Fix the side keel along the elevation line. The function of the side keel is to seal the edge of the ceiling. The commonly used size of the side keel is 25*25mm, and its color should be the same as that of the PVC gusset. The side keel is mostly made of cement nails Fastened to the wall post.
3. Determine the position line of the keel, because each PVC gusset is a formed decorative panel, and generally cannot be cut into pieces. In order to ensure the integrity of the ceiling finish and the reliability of installation, it is necessary to The size of the gusset plate and the area size of the ceiling are used to arrange the structural dimensions of the ceiling frame. The basic layout of the PVC gusset veneer is: the plate combination should be complete, when the edges are left around, the edges should be symmetrical and even, and the arranged dragon skeleton position line should be drawn on the top of the elevation line.
4. The distance between the main keel hanging points should be selected according to the design recommended series. The middle part should be arched, and the keel arching height should not be less than 1/200 of the room surface span. After the main keel is installed, the position and height should be corrected in time. To control the leveling of the dragon skeleton, first pull out the vertical and horizontal elevation control lines, start from one end, and adjust the suspension height of the boom while installing. After the large surface is flat, adjust some single keels with curved edges until the flatness meets the requirements.
5. The boom should be straight and have sufficient bearing capacity. When the boom needs to be extended, it must be welded firmly, and the weld seam is even and full. Anti-rust treatment shall be carried out, and the distance between the boom and the end of the main keel shall not exceed 300mm, otherwise a boom shall be added to prevent the main keel from falling, and the secondary keel (the same below as the middle keel or the small keel) shall be installed close to the main keel.
6. Completely correct the position and levelness of the primary and secondary keels. The connecting pieces should be installed in dislocation, check the installed ceiling skeleton, it should be firm and reliable, and the next step of construction can be carried out only after complying with the relevant specifications.
7. When installing the PVC gusset, the secondary bone should be straightened. The pinch plate should be flat and not warped, and the flatness error of the ceiling plane should not exceed 5mm.
3. Acceptance criteria for PVC gusset installation
1. All kinds of keel ceilings must be fixed firmly. Level and check that the mounting position is correct.
2. The variety, specification, color of the materials used in the ceiling project, as well as the basic structure and fixing method should meet the design requirements.
3. The wooden frame structure of the ceiling should meet the fire protection requirements.
4. The specifications of the wooden squares used for the wooden frame should be in accordance with the design requirements. The wooden squares should be glued and then fixed with nails. The side that contacts the PVC gusset must be planed.
5. The PVC gusset should not have defects such as bubbles, peeling, cracks, missing corners, dirt and pattern defects. The surface should be flat, the edges should be neat, and the color should be consistent; the hole spacing of the perforated plate should be Arranged neatly, plywood, wood fiberboard should not be degummed, discolored and decayed.
6. When pasting or painting the PVC gusset, the joints should be painted with white latex and pasted with muslin cloth, and both sides of the joint should overlap at least 5mm.
7. When the plywood surface is painted with varnish, the wood grain and color of the adjacent board surface should be similar; if plywood and medium density fiberboard are fixed with nails, the nail distance is 80-100mm, and the nail length is 25 mm. -35mm, the nail cap should be flattened and enter the board surface for 0.5-1mm, and the nail hole should be smoothed with oily putty.
4. Precautions for installing PVC gusset ceiling
1. After the wall tiles of the kitchen and bathroom are pasted, notify the gusset manufacturer to come and measure .
2. Electric water heaters and gas water heaters should be installed in place, and power lines for lighting and exhaust should be reserved.
3. Before installing the ceiling, buy the Yuba exhaust fan (not required for the integrated ceiling), and get it to the site. The opening position of the exhaust hood is determined by the cabinet manufacturer.
4. Ceiling lamps, if they are embedded, should be bought and brought to the scene, ordinary ones are not needed.
5. Please confirm the installation position of the above electrical appliances so that the installation workers can open holes.
6. Now, the upper edge of most of the balcony kitchen and bathroom windows is lower than the size of the ceiling, please prepare the wood board (or kitchen cabinet board) so that the ceiling installation workers can seal these parts.
