Measure the installation area accurately and prepare for installation; Install the take-up line; Drive expansion screws and hang suspenders; Install the hook, and install the light steel keel on the ceiling; Attach the triangle keel with the hanging pieces installed tightly to the light steel keel vertically below the light steel keel; Press the gusset plate into the triangular keel joint to ensure that it is perpendicular to each other; Install electrical appliances; Check and adjust.

1. Use a horizontal tube to copy out the horizontal line, check the flatness twice repeatedly, and use a chalk line to pop up the baseline. If the original ceiling is not level, the ceiling should be made horizontally or along the original ceiling, which should be determined by the customer after consulting the designers.

2. Be familiar with the drawings, determine the dimensions, and carry out construction disclosure. The arc-shaped top surface modeling should be laid out on the ground first, and then the top can be erected after it is confirmed. And ensure smooth lines.

3. The main reinforcement of the suspended ceiling shall be no less than 31×51 wooden keels, with the spacing of 811-1111, and the expansion of 111×8 steel shall be fixed, with the length of 1m? The dosage is one. Steel expansion should be made in the gap of precast slab as far as possible. Do not use iron wire as hanger bar. The steel expansion nut should be pressed against the wooden keel.

4. The secondary keel of the ceiling shall be no less than 25×35 wooden keel, which shall be selected and used. The leftover materials shall not be used for the ceiling grille, but only as steel hanger. The dragon skeleton should be pushed out of the bottom surface before it can be used. The keel spacing of plasterboard is 411×411, the keel spacing of laminate is 311×311, and the wooden keel spacing of gusset ceiling between kitchen and bathroom is not more than 611×611. Light steel keel spacing shall be adopted for construction according to material requirements.

5. Attention should be paid to the position of lamps and lanterns when playing wooden keel grille. There should be no wooden keel at the opening of downlight. The ceiling and ceiling lamp should be reinforced separately, and the main lamp of the living room should be fixed with steel expansion. Light lamps can be hung on the main keel, and lamps or ceiling fans weighing more than 3 kg shall not be connected with the ceiling keel, and hooks shall be set up separately.

6. Before using gypsum board, it must be divided into blocks by elastic lines. When sealing the board, leave a seam of 3mm, use special screws to fix it, sink it into gypsum board for 1.5-1mm, and the nail spacing is 151-171 mm.. Fixation should be from the middle of the plate to the four sides, and multi-point simultaneous operation is not allowed. There must be a keel at the junction of slab joints. 2 meters by foot inspection, flatness error within 2 mm..

7. Before the sealing plate, it is necessary to snap lines and block, so as to ensure that the nails are nailed on the wooden keel, the nail spacing is 81-151, the nail length is 25-35, and the nail holes are painted with antirust paint. If latex paint is used, alkyd varnish must be used for roll coating to prevent the laminate from turning color.

when using aluminum gusset plates and baking finish gusset plates, you should know the specifications of gusset plates, and stock them reasonably according to the field size. The ceiling of the bathroom must also be made of steel expansion and painted with fire retardant paint, and the ceiling of the kitchen and bathroom should be as high as possible.

9. When sealing the board, pay attention to dragging the lamp line out of the top surface, determine the position of the downlight on the cover panel according to the construction drawing, and pull out the thread end.

11. When sealing plastic gusset plates, aluminum gusset plates and painted panels with wooden keels, attention should be paid to the fact that the panel surface is not damaged, and the seams of the convergent line of gusset plates, the internal angle line and the external angle line should be tight. You can nail the gusset plates and lines together from the top with straight nails, and make sure that there is no water leakage on the top floor. Determine the position of electrical wiring and mark it accordingly.

11. The total height of the dark band is 121-211. All dark bands should adopt double-layer Yinyu brand neon tubes. The front baffle of the dark band should use jiuli board or double-layer five-centimeter board or woodwork board, and the rear baffle should use five-layer board. Panel ceiling should be made of wooden keel at the grass-roots level, sealed with a layer of five boards, and then sealed with panels.

Extended information

1. Before installing the keel, handover inspection shall be conducted on the clear height of the room, the elevation of the hole and the elevation of the ceiling pipes, equipment and their supports according to the design requirements.

2. The wooden suspenders, wooden keels and wooden decorative panels of the suspended ceiling project must be subjected to fire prevention treatment, and shall comply with the provisions of the relevant design fire protection codes.

3. The embedded parts, steel suspenders and steel suspenders in the suspended ceiling project should be rusted.

4. Before installing the panel, the debugging and acceptance of the pipes and equipment in the ceiling should be completed.

5. The spacing between suspenders shall not be greater than 1211mm, and the distance between suspenders and the end of main keel shall not be greater than 311mm. When it is greater than 311mm, suspenders shall be added. When the length of the boom is greater than 1.5m, anti-support shall be set. When the boom meets the equipment, the boom should be adjusted and added.

6. Heavy lamps, electric fans and other heavy equipment are strictly prohibited to be installed on the keel of the suspended ceiling project.

7. The bottom surface of the ceiling should be neat with the bottom surface of the light box and Yuba.
