Selection skills of gusset plate for integrated ceiling
I. Material types of joint plates
At present, the gusset plates of integrated ceiling include coated board, nano-board, roller coated board, sanding board and so on. Among them, the roll coating plate is directly coated with baking paint on the aluminum gusset plate under high temperature environment, and the coated plate is glued. Roller coating is relatively environmentally friendly and has better fire prevention skills.
Second, identify the quality of the pinch plate.
The quality of the gusset plate of integrated ceiling can be identified by some simple methods. First, the surface of pinch plate can be observed, and the surface of high-quality pinch plate is smooth and soft. You can also burn the corners of the aluminum gusset plate with a lighter. Inferior aluminum gusset plates will produce pungent smell, while high-quality aluminum gusset plates will not. You can also tap the aluminum gusset plate with your fingers. After tapping, the coating plate sounds dull and the roller coating plate sounds crisp.
Third, compare the gusset materials.
Although the main component of the gusset plate of the integrated ceiling is aluminum, the aluminum material also has the difference between primary aluminum and recycled aluminum. The quality of primary aluminum gusset plate is better and the price is slightly higher. You need to ask the merchants clearly. If you buy recycled aluminum gusset plates, the hardness and strength will be slightly worse.
Fourthly, compare the thickness of gusset plate.
The thickness of gusset plate of integrated ceiling is 0.8, 0.6 mm, 0.4 mm, 0.3 mm, etc. It is recommended to buy an aluminum gusset plate with a thickness of 0.6 mm, and the thickness can be confirmed by observing the model description of the aluminum gusset plate. Although the price of 0.3 mm and 0.4 mm aluminum gusset plates is slightly lower, their strength and bearing capacity are insufficient.
Fifth, the film-coated board is more difficult.
If you choose the aluminum gusset plate covered with plastic film, it should be noted that the thickness of the aluminum gusset plate needs to be subtracted from the thickness of the plastic film and cannot be deceived by unscrupulous merchants, resulting in that the purchased aluminum gusset plate is called 0.8 mm, and the actual thickness is only 0.5 mm (the film thickness is 0.3mm).
Key points of integrated ceiling construction
1, the elastic line ensures the level.
First of all, the installation of integrated ceiling needs to be flexible to ensure the level. Generally, according to the floor elevation horizontal line, use a ruler to measure vertically to the ceiling design elevation, and play on the roof keel position line and the ceiling elevation horizontal line on the wall.
2, install the main keel boom
After playing the ceiling elevation horizontal line and the main keel position line, determine the elevation of the lower end of the boom. According to the position of the main keel and the hanging spacing, fix one end of the suspender without pulling wires under the floor with expansion bolts.
3. Install the main keel and the secondary keel
Install hanger nuts, prepare hanger signals in advance on the main keel, insert the assembled hanger into the corresponding hanger bolts according to the position of the step line, tighten the nuts, connect the main keel, install connectors, adjust the elevation and straightness of stay wires, and install additional main keel at the mouth of the cave for positioning connection. According to the played sub-keel step line, put the triangular pendant of the last keel, and hang the sub-keel on the main keel through the triangular pendant according to the spacing of the main keel specified in the design.
4. Install integrated ceiling
When installing the integrated ceiling, gently press it in sequence along the flanging parts, completely clamp both sides of the square plate into the secondary keel, and then push it tightly. Rough handling is strictly prohibited.
5. Install the electrical module
The integrated ceiling is generally installed by the manufacturer, and the installer must hold a professional electrician qualification certificate and protect the exposed wires. After installation, do a power-on test first, and then adjust it with a leather hammer to ensure that there is no gap.
After the installation and construction of the electrical module is completed, it is necessary to check whether the function of the current collector is normal. The owner can turn on the switch to check whether the functional appliances are working normally and whether the noise is too high.
The above is the introduction of the purchase skills of gusset plates of integrated ceiling and the key points of integrated ceiling construction compiled by Bian Xiao. I hope it helps you.
