2. Stick the corner line required for the wall below the horizontal line, and the upper edge of the corner line is aligned with the horizontal straight line. Mark the holes on the sideline with the hole spacing 10 ~ 15. .

3. hit 4 with an electric hammer? When drilling, the crosshair must be accurately centered, and the hole depth is about 30? .

4, the expansion tube into the hole, the expansion tube shall not exceed the installation wall.

5. According to the angle of the corner, cut the two ends of each corner line into half corners, and the standard corner is 90? , that is, the ends of the corner line are cut into 45? , and use 4? 0 Self-tapping screws shall be fastened to trim the corner line, and the diagonal of the corner line shall be straight, and the clearance shall be ≤0.5? .

6. If corner lines must be installed above the tiles, wooden strips should be installed on the wall before installing corner lines. The thickness of batten is equal to that of ceramic tile, and the surface of batten is flush with the surface of ceramic tile. The installation method is the same as the corner line.

7. In addition, when installing corner lines on the surface of ceramic tiles, you can also stick them on the ceramic tiles with super glue such as 502 glue, so that all fixed battens can be omitted. .

Verb (abbreviation of verb) main keel installation

1. When installing the fixed batten, measure 30 upward on the plane of the corner line respectively. Distance, line drawing with Mo Dou cross line as the bottom line of the batten.

2, and then about 40 above the horizontal line? Draw a horizontal line in the place, with 8? - 10? The drill bit is drilled with fixed battens, and the hole spacing is 20-30? The hole depth is about 50? .

3, put the batten into the hole, batten shall not be exposed to the wall, and draw a straight line under the small batten to mark the hole position.

4. Nail the fixed batten with ordinary steel nails and fix the fixed batten firmly.

5. Generally, the installation spacing of the main keel is 600? However, if the design according to the drawing hinders the installation of the main engine, the spacing of the main keel must be adjusted for reasonable distribution, and the thickness of the main keel is generally 5- 10? , with 4? Five self-tapping screws will fix the main keel on the fixed batten to ensure firm. .

Six, the installation of integrated hook

1. When the length of the main keel is greater than 150cm, add a hook in the middle, hang the appropriate perforated mounting point from the ceiling with soft thin iron wire, and mark it.

2. Use an electric hammer to hit a diameter of 8? , 50 deep? Hole (be careful not to be too deep), then determine the length of the hook, insert one end of the hook with a telescopic tube into the hole, tighten the nut, and hang the hook (38 hanger) at the lower end to adjust it to the optimal height, and fix the hook firmly with the main keel with machine-repair screws. .

Seven, the installation of triangular keel

1. Reasonably distribute the installation positions of hoisting parts on the main keel and mark them properly. The center line of the first triangular keel against the wall is 305? Other triangular keel spacing is 300? (300*300 gusset plate can be used to measure the spacing), a hanger is set on the triangular keel, and the triangular keel is fixedly connected with the main keel through the hanger.

2. The gap between the aluminum gusset plate against the wall and the wall is 5? About, mainly consider the flatness of the wall and the beauty of the aluminum gusset plate. If the angle of corner is deviated or the length of symmetry plane is inconsistent, it should be allocated reasonably. If the error is large, the triangular keel shall be installed by drawing a right angle line on the assembly surface.

3. When installing the triangular keel, the size must be accurate, and the clearance of each triangular keel is 300? (Except the first one against the wall) The bottom plane of the triangular keel is 3.5-4 higher than the edge line? Before installing the triangular keel, it should be determined from which side to start the installation, which will be beautiful and save time.

4. The triangular hanger is fixed on the main keel, which must be perforated, and cannot be loosened with self-tapping screws. .

Eight, the installation of the host

1. Install the electrical main engine on the triangular keel according to the drawing design. First, try to install the main engine with aluminum gusset plate to determine the correct position of the main engine. Stick the "drilling template" in the box to the position where the main engine needs to be fixed, or drill holes directly according to the actual installation hole position of the main engine, and drill 2.5 holes with an electric drill. Hole, and then use the tapping screw attached to the main engine to firmly fix the main engine on the triangular keel.

2, lamp warm host, air warm host should be connected to the N line, and connected to the L line (switch).

3. When installing the lamp warm host, screw in the heating bulb first, loosen the movable screw of the lamp warm bracket, and adjust the position of the heating bulb. The exposure standard of the heating bulb is: the aluminum layer of the heating bulb is flush with the panel, and the size is 30? The PTC heating block of the air-heating host is 5? .

4. The installation position of the ventilator should be within 1300mm from the vent, and the length of the ventilation pipe should be 1500mm. Pay attention to the ventilation hole above the ceiling and slightly below the air outlet of the ventilator to prevent the dew in the ventilation pipe from flowing back. The diameter of the vent hole is 100 mm.

5. After all the hosts are installed and fixed, conduct power-on test to ensure that the hosts can be used normally.

Nine, aluminum gusset plate assembly

1. gloves must be worn when installing the aluminum gusset plate!

2. Tear off the plastic film on the four sides of the aluminum gusset plate first, and then install it from the keel of the main engine. Assemble them to the wall one by one, keep the flat-fell seam gap consistent and align the four corners of the gusset plate. Pull all clamping positions on the trimming line to 60 degrees, and then start the assembly of the first keel aluminum gusset plate. When the last two pieces arrive, measure the actual size. If cutting is needed, it should be cut first and then assembled. The cutting surface should be stuck between the clamping locating piece and the trimming line surface. If necessary, pull the clamping positioning piece to 90 degrees. The aluminum gusset plate and trimming line should be kept flat (note: if it is not flat, it should be fixed with wood blocks).

3. Do not assemble the last two aluminum gusset plates. Assemble other aluminum gusset plates and panels first, keep the whole flat, with consistent gaps and flat-fell seams in a straight line.

4. Finally assemble and measure the remaining dimensions. If the aluminum gusset needs to be cut, it should be cut. After the last aluminum gusset plate is installed and fixed, the last second aluminum gusset plate is assembled. Gap conforms to the requirements of the whole, flat-fell seam and the whole into a straight line. .

X. final inspection

1, four diagonal corners of the aluminum gusset plate are flat and uniform.

2. The drawing stripes of aluminum gusset plates are in the same direction, and the gap between aluminum gusset plates is less than1mm. ..

3. All hosts can be used normally.

4. Clean up the site and pack the garbage away with garbage bags.
