The installation position of the ventilation fan should be within 1300mm from the ventilation hole and the length of the ventilation pipe should be 1500mm. Note that the ventilation hole should be above the ceiling and slightly lower than the outlet of the ventilation fan to prevent dew flow in the ventilation pipe. The diameter of the ventilation holes is 100mm.
AIA integrated ceiling
First, draw a sketch
1. Measure in the field, determine the distribution of room pipes, the height of the room, the location of room facilities, and the location of ventilation windows.
2. According to the size and shape of the room, draw a sketch of the room.
Second, the design of the ceiling
1. Select the color of the gusset and the model and quantity of the host, and design the best collocation plan. (can be done on the computer)
2. Calculate the amount of main keel, hook, triangle keel and corner line, and determine their position.
Third, the pre-installation work
1. The pretreatment of the ceiling, determine the installation height of the ceiling, the middle sandwich is larger than 300mm, use the horizontal pipe to draw lines at four corners, and use the ink fountain to pop the horizontal line.
2. Determine the position of the ventilation window and use the electric hammer on the wall to make a round hole with a diameter of 100mm.
3. The wire is pre-embedded with 2 lighting lines and 5 heaters. In order to ensure normal use, 1 or 2 more can be embedded.
4. Pipelines, gas pipes and other pipelines are to be inspected for leakage and leakage.
Fourth, the corner line installation
1. The corner lines required for the four sides of the room are cut according to the actual size of the wall.
2. Adhere the required corner line of the wall to the bottom of the horizontal line. The line on the corner line is aligned with the horizontal line, and the hole is marked in the hole of the line. The hole distance is 10~15cm.
3, use electric hammer to hit 4mm hole, when drilling must be accurate with crossed cross as the center point, hole depth of about 30mm.
4. Drive the expansion tube into the hole. The expansion tube must not exceed the installation wall.
5. According to the angle of the corner, cut the two ends of each corner line into half of the corner of the wall. The standard wall angle is 90°, that is, the two ends of the corner line are cut into 45° and fastened with 4×20 self-tapping screws. Trimming the corner line, pay attention to the diagonal corner line, the gap ≤ 0.5mm.
6. If the corner line must be installed above the tile, install the wooden bar along the wall before installing the corner line. The thickness of the bar is equal to the thickness of the tile. The surface of the bar is flush with the surface of the tile. The installation method is the same as the installation of the corner line.
7, in addition, the corner line installed on the surface of the tile can also use strong glue, such as 502 glue paste on the tiles, so that all the fixed wooden strips can be saved.
Fifth, the main keel installation
1. Fix the installation of the wooden strips, and measure the distance up to 30 mm on the plane of the corner lines. Mark the lines and use the ink fountains as the bottom line of the wooden strips.
2, then in the top of the horizontal line about 40mm place bomb horizontal line, and use 8mm-10mm drill bit to install the fixed wooden bar, hole spacing is 20-30mm, hole depth of about 50mm.
3, the wood into the hole, the wooden bar shall not be exposed on the wall, and draw a straight line under the small wooden bar hole mark.
4. Use ordinary steel nails to screw into the fixed wooden bar and fix the fixed bar firmly.
5, the general main keel installation spacing is 600cm, but according to the design of drawings in the installation of the host when there are obstacles, the main keel spacing must be adjusted for a reasonable distribution, the main keel thickness is generally 5-10cm, with ? 4 × 15 The self-tapping screws secure the main keel to the fixed wooden strip and ensure firmness.
Sixth, hook installation
1. If the length of the main keel exceeds 150cm, a hook should be added between the main keel. Use a soft and thin wire to hang a suitable punching and mounting point from the ceiling and mark it.
2. Use an electric hammer to drill a hole with a diameter of 8mm and a depth of 50mm (be careful not to be too deep), then determine the length of the hook, insert the end of the expansion pipe into the hole, tighten the nut, and confirm the firmness. Lower the upper hooks (38 hangers) to the optimal height and fix the hooks to the main keel firmly with the machine screws.
Seventh, the installation of triangular keel
1. Properly distribute the position where the hanger is installed on the main keel and mark it. The distance between the centerline of the first triangle keel against the wall is 305mm from the wall surface, the distance between the other triangle keel is 300mm (the span can be measured with a 300*300 gusset plate), the hanging piece is placed on the triangular keel, and the crane is lifted. The triangular keel is fixedly connected to the main keel.
2. The gap between the wall of the aluminum buckle plate and the wall surface is about 5mm, mainly considering the flatness of the wall surface and the appearance of the aluminum buckle plate. If there is deviation in the angle of the corner or the length of the symmetry plane is inconsistent, it should be reasonably allocated. If the error is relatively large, the triangle should be installed on the assembly surface to pull out the right angle.
3, the installation of triangular keel, the size must be accurate, each triangular keel gap is 300mm (except for the first outside the wall) triangular keel plane is 3.5-4mm higher than the corner line, before the installation of triangular keel First determine from which side to start the installation in order to be beautiful and save time.
4. The triangular hangers are fixed on the main keel and must be perforated. They cannot be loosened with a self-tapping screw.
Eight, the installation of the host
1, according to the design of the drawings, install the electrical mainframe on the triangular keel, first test assembly with the aluminum pinch, determine the correct location of the host, the box inside the "drill template" in the fixed host required position or directly in the installation In the case of a host computer, holes are drilled according to the actual machine mounting holes, and a 2.5mm hole is drilled with an electric drill. Then, the host machine is firmly fixed on the triangular keel using the self-tapping screws attached to the host machine.
2, warm host, warm air host should be connected to the N line, and connect the L line (switch)
3. When installing the heating unit, first screw in the heating bulb, loosen the screw of the warm bracket, and adjust the position of the heating bulb. The standard of the heating bulb is: the aluminum layer of the heating bulb is flush with the panel, and the size is 30mm, PTC heating block of air-heating machine is 5mm away from the panel.
4. The installation position of the ventilation fan should be within 1300mm from the ventilation hole and the length of the ventilation pipe should be 1500mm. Note that the ventilation hole should be above the ceiling and slightly lower than the outlet of the ventilation fan to prevent the backflow of dew in the ventilation pipe. The diameter of the ventilation holes is 100mm.
5, the use of the host are installed and fixed after the power test to ensure that the host can be used normally.
Nine, aluminum buckle plate assembly
1, install the aluminum buckle plate must bring gloves!
2. First tear off the four sides of the aluminum buckle plate, and then start the installation from the main frame of the main frame. In the block-by-block installation to the edge of the wall, the gaps of the joints are the same, and the four corners of the buckle plate are aligned. Pull all the trim points on the trimming line to 60 degrees, and then start the assembly of the aluminum buckle on the first keel. When the last two pieces are finished, measure the actual size. If you need to cut, you should cut and reassemble. The cutting surface should be stuck in the middle of the card piece and trimming line surface. If necessary, pull the card to 90 degrees. The aluminum buckle plate and the trimming angle line should remain flat (Note: unevenness occurs, and the block is fixed with a wooden block).
3, the last two aluminum buckle plate, do not first assembly, first, the other aluminum buckle plate, panel assembly, keep the overall leveling, the same gap, patchwork into a straight line.
