Function and installation method of dragon skeleton
The role of dragon skeleton
1. Main keel: The main keel is used to bear the load on the ceiling and provide a bearing surface for the erection of the auxiliary keel.
2. Auxiliary keel: Auxiliary keel refers to the distributed load-bearing keel in the load-bearing of suspended ceiling. The main function of the auxiliary keel is to disperse the bearing surface of the ceiling, and the laying of gypsum board provides the bearing surface.
3. Fixing gypsum board: Laying, installing and fixing gypsum board according to the shape.
4. Plasterboard surface decoration: refers to the surface treatment of installed plasterboard, which generally includes the treatment of gaps between plasterboards, waterproofing of exposed parts of screws on plasterboard surface, painting of putty and latex paint on plasterboard surface, etc.
Generally speaking, when we decorate our home, especially when we are doing the ceiling, if we don't install the dragon skeleton, then the effect of the ceiling is invisible and tangible, so many friends will choose the dragon skeleton to pave the way for the ceiling shape when doing the ceiling.
method of erection
1, corner line installation
Assembly bars shall be installed stably and firmly, and the installation height shall be determined, and a horizontal line shall be drawn. After the ceramic tile is pasted, the matching corner line of the integrated ceiling should be firmly fixed on the ceramic tile horizontally without obvious gaps.
2. Installation of keel
Under the suspender and light steel keel, the distance between the suspender and keel should correspond to the size of the panel one by one. Drill expansion holes at the top and fix all suspenders. The lower opening of the suspender is connected with the hook, and then the main keel frame is fixed in the middle of the hook. Adjust the height nut so that the bottom surface of the main keel is 3 cm away from the upper plane line of the side strip, and fix it.
3, pay the installation of the keel
According to the actual installation length, cut off the required auxiliary keels by 5mm, put on triangular lifting pieces, and temporarily anchor all auxiliary keels on the main keels with triangular lifting pieces according to the drawing requirements.
4. Install the gusset plate
Wear clean gloves, and consider the overall beauty and bilateral symmetry when installing the gusset plate.
Cutting method: fix the template, carve it with a utility knife and ruler for more than three times, cut the hem into a 90-degree angle with scissors, and fold it by hand for 2-3 times. Clamp the corresponding surface of template cutting on the auxiliary keel, put the cutting surface on the edge-closing strip, and pull out the edge-closing strip to clamp the template. At this time, the triangular hanger can be clamped with the Gang Qian and the main keel.
When installing the central formwork, clamp the two corresponding surfaces of the formwork in the auxiliary keel respectively, control the gap between the formwork and keep the flat-fell seam straight. Note: After each row of formwork is installed, the triangle pendant shall be fastened with Gang Qian and main keel.
5, the installation of the host
When the installation position of the heating host is satisfied according to the drawing design, replace the template with the host panel to confirm the accurate installation position of the host; Then put the main chassis above the auxiliary keel and fix it. When installing (embedding) electrical appliances, the interface between the panel and the electrical appliances should be smooth and seamless.
6. Top wiring and mouth panel
Run the wiring at the top to determine where the lamps need to be installed and where the kitchen and bathroom appliances need to be installed, and arrange the wiring in advance. The gusset plate is directly related to the overall effect of the ceiling. Not only flat, but also straight.

Aluminum gusset plate: it is a new type of ceiling material, which is mainly used in bathroom or kitchen in home decoration. Its performance is not only fire-proof and moisture-proof, but also anti-corrosion, anti-static, sound-absorbing and sound-insulating, beautiful and durable, and it belongs to the first-class ceiling material. There are rectangles and squares, and there are two kinds of planes and perforated surfaces. The price of domestic aluminum gusset plates is about 60 yuan per square meter, and the price of imported aluminum gusset plates is about 180-400 yuan. The difference between the two is mainly in hardness. The inspection of aluminum gusset plate mainly depends on the gloss thickness of paint film.
