The high-speed rail sound insulation plate is mainly composed of foundation, column and vertical plate. The vertical plate is the main component of the sound barrier for noise reduction. It can be fixed in the slot of the column by means of special high-strength springs, bolts and angle steel to form a sound insulation board.
The vertical plate is made of aluminum alloy plates, usually 1000 series or 5754 aluminum. In the city near the sea, it has has extremely high requirements on the strength and corrosion resistance of the aluminum plate. 5754 aluminum plate noise barrier is mostly used.
Aluminum plate noise barrier5A02 aluminum plate is a high magnesium alloy with good strength, corrosion resistance and machinability among non-heat treatable alloys. Excellent corrosion resistance makes 5a02 alloy aluminum plate widely used in automobiles, aircraft welding parts, subway light rails, pressure vessels that require strict fire protection.
Aluminum tread plateOn the basis of aluminum plate, it is an aluminum product that forms various patterns on the surface after calendering. It has three main features: load-bearing, thermal insulation and sound insulation. It is widely used in packaging, construction, curtain wall, etc.
