1, the role of wood grille ceiling wood grille ceiling is different from other ceiling projects, should be attributed to joinery decoration, wood grille ceiling is the family decoration corridors, entrances, restaurants, and a larger roof and other spaces are often used methods.
The wooden grille ceiling can not only beautify the top, but also achieve the purpose of adjusting the lighting and increasing the overall decoration effect of the environment. It requires generous design, reasonable structure, beautiful appearance, firm fixation, smooth surface, uniform color, reasonable internal lighting layout, complete decorative paint film, no scratches, no pollution, etc.
2. The installation of the wooden grille frame of the wooden grille ceiling should be based on the accurate measurement of the ceiling size. The keel should be finished, the surface should be planed, the interface should be opened, and the horizontal and vertical keel junctions should be opened. Lapping, and should be flame retardant brushing treatment.
During the installation, the elevation control line and the suspender installation line shall be popped according to the design. The wooden mold shall be drilled on the wall and the ceiling, and the ceiling hanging piece shall be fixed on the keel and the hook by using a thick wire. When installing, the integral lifting method is adopted to move the wooden grille frame to the entire height line and connect it with the ceiling hanging pieces. After all the hanging pieces are connected with the grille frame, the grille surface is leveled by adjusting the length of the hanging pieces. After the grille frame is adjusted to be flush with the control line, the surrounding wooden keel is fixed on the wall.
The surface treatment of the wooden grille skeleton is usually done by sticking more expensive wood, installing lighting fixtures and closing decorative lines. The lighting fixtures can be installed when the wooden grille skeleton is manufactured, and the power supply is connected after lifting. The decoration strips shall be installed on the ground. After the ceiling installation, the strips shall be sealed at the closing line. After the wooden grille is installed, the decorative surface shall be painted with oil and the frosted glass shall be installed after brushing.
3. Common quality problems and treatment methods of grille ceilings The common quality defects of wooden grille ceilings are uneven or irregular, uneven surfaces, collapse, and arching. The grid is uneven or not square, mainly due to the fact that the foundation walls are not square or the vertical and horizontal grille openings are not vertical. Therefore, before installing the wooden grille skeleton, deal with the foundation wall to find the square, first use the ruler to measure the angle and the angle of each side, if the error is not large, you can use the putty to shave the wall to find the square, if the error is large, You should first pad the board and then level it with putty. When vertically lining the keel grid, it must be vertical. Otherwise, it should be processed before installation.
The main reasons for the unevenness, collapse, and arching are due to the fact that, besides strict construction, wood deformation, excessive thickness of frosted glass, and excessive weight of lighting fixtures are also important reasons. Therefore, in the construction should choose not easily deformed pine wood frame, frosted glass to 3mm thick is appropriate, lighting can be installed on the ceiling or choose lightweight materials to prevent the ceiling load is too heavy. If there is arching, the hanging parts can be adjusted so that the top surface is flat.
4. Acceptance Criteria 1 Wooden grille production and purchase of finished products require that the surface be smooth, smooth, non-crack, no frugal, small grid-shaped, solid node;
After the 2 units are assembled into a unit, the acceptance criteria are the same as the wormhole ceiling;
5. Passed ISO9001 quality management system certification.
6. Accept OEM manufacturing and produce on your design.
