Description

Technical Field

There are mainly two types, one is home improvement integrated aluminum gusset plates, and the other is engineering aluminum gusset plates. Aluminum gusset plates have the dual properties of metal and plastic. Their vibration attenuation coefficient is six times that of pure aluminum plates, the air sound insulation is better than other plates, and the thermal conductivity is small. It is an ideal sound insulation, heat insulation and shockproof building material, and it also has different functions according to different aluminum alloys.

[0003] The first type is aluminum-magnesium alloy, which contains some magnesium. The biggest advantage of this material is its good antioxidant ability. At the same time, because of the addition of an appropriate amount of magnesium, its strength and rigidity are improved, making it the best material for suspended ceilings. The second type is aluminum-manganese alloy. The strength and rigidity of this plate are slightly better than those of aluminum-magnesium alloy, but its antioxidant ability is slightly insufficient. The third type is aluminum alloy. This plate contains less manganese and magnesium, so its strength and rigidity are significantly lower than those of aluminum-magnesium alloy and aluminum-manganese alloy, and its antioxidant ability is average.

[0004] However, the existing aluminum alloy cover plates are all installed by snap-on installation. After long-term load-bearing use, the aluminum gusset plates cannot be fixed, resulting in collapse, shaking and falling, causing casualties and economic losses.
