The aluminum square tube ceiling is a kind of ceiling made of aluminum alloy, which has very good plasticity and corrosion resistance. Aluminum square pipe ceiling is a kind of metal ceiling that can prevent corrosion. This kind of ceiling has very good weldability and good processability. Aluminum square pipe ceiling is a kind of shape, which looks like a square ceiling. This kind of ceiling can prevent fire and resist high temperature. There are many specifications of aluminum square pipe ceiling. Do you know the specifications of aluminum square pipe ceiling? The following small series introduces the specifications of aluminum square pipe ceiling for everyone.

specifications of aluminum square pipe ceiling

At present, there are mainly three specifications: 27.2, 31.8 and 31.6. If you measure, you can directly measure the diameter with a ruler, but it may not guarantee that your ruler passes through the center of the circle, so the measurement may not be accurate. There is also a more accurate method, that is, wrap a thin wire around the seat tube, measure the length (that is, circumference) of the wire, and divide it by pi to get the result ~ I hope the answer is helpful.

Construction technology

1. Sprinkle the ceiling horizontal control line and draw the keel grading line:

Measure the ceiling design height from the indoor predetermined leveling line, and pop up the ceiling surface leveling line with chalk lines. At the same time, according to the ceiling plan, mark the fixed point of the suspender at the position where the main keel pops up on the concrete roof. The main keel is generally divided from the center of the ceiling to both sides. The distance between main keel and suspender is 911～1211mm, generally 1111mm.

2. Fix the hanging bar:

Fix the hanging bar with expansion bolts. Φ 6 boom can be used. Hangers can be cold-drawn steel bars or round steel bars, and round steel bars should be straightened mechanically. Is one end of the boom the same? 31×31×3, L=51 angle steel welding (the aperture of angle steel should be determined according to the diameter of boom and expansion bolt), and the other end is threaded with tapping thread, and the length of thread is not less than 111 mm. You can also buy a finished screw rod to weld with boom. The fabricated boom should be rustproof. The boom should be fixed on the floor with expansion bolts, and punched with impact hammer. The aperture should be slightly larger than the diameter of the expansion bolts.

3. Installation of light steel keel:

Light steel keel should be hung on the derrick (if the ceiling is low, this process can be omitted and the next process can be directly carried out). Generally, 38 series light steel keels are used, with a spacing of 911～1211mm, generally taking 1111mm. Light steel keel should be installed in parallel with the room in the long direction, and at the same time, it should arch, and the arch height should be 1/511 of the short span of the room. The cantilever section of light steel keel should not be greater than 311mm, otherwise the suspender should be added. The extension of the main keel should be butted, and the butt joints of adjacent keels should be staggered. After hanging the light steel keel, it should be basically leveled, and the suspender nut should be tightened.

for suspended ceilings with a span of more than 15m, a large keel should be added every 15m in the direction perpendicular to the main keel, and it should be firmly connected with the main keel.

4. Assembly of the main and auxiliary bones of the grille: pre-assemble the main and auxiliary bones of the grille below according to the requirements of the design drawings.

5. Installation of cotton layer of aluminum grille.

Precautions

For the light trough and other equipment in the ceiling, if the weight is light, it can be directly hung on the main keel. In case of heavy articles, hanger bars or suspension structures should be added separately.

according to the panel frame diagram, ink lines pop up on the gypsum board surface, and are cut and shaped by high-speed reciprocating saw. For special-shaped panels, curved saws are used for processing, and the processed cuts are arranged by electric trimming machine to ensure that the cuts are flat and smooth.

the above is the specification introduction of aluminum square pipe ceiling. There are many specifications of aluminum square pipe ceiling. You can choose the specifications of aluminum square pipe ceiling according to your own fortune specifications. Aluminum square pipe is widely used in China, and it is one of the most promising alloys at present. The oxidation of aluminum square pipe ceiling is relatively good and it is easy to color. Aluminum square tube is a good building decoration material, which can be printed with various patterns and is very easy to process. Nowadays, many people choose aluminum square pipe ceiling in their bathrooms, because it can prevent moisture and corrosion.
