The structure of the metal Noise Barrier can be divided into two parts, the above ground and the underground. The above ground part is a huge, continuous slab facade with a thickness of about 20cm that shields the sound wave. Its top is a fan-shaped sound absorber or an inclination shield. What are the regulations for the metal Noise Barrier screen?
In principle, the height and width of the metal Noise Barrier are based on the direct sound waves that cut off the sound source to the receiving point. In order to improve the shielding effect, the height of the barrier is usually not less than 1.3 times the height of the air inlet; to avoid affecting the air inlet, The distance between the barrier and the air inlet is usually not less than twice the height of the air inlet. The assembly of the metal Noise Barrier sound-absorbing screen panel and the back panel, side panel and internal keel should adopt the snap-on connection method. If other connection methods are used, they must comply with the regulations.
When the metal Noise Barrier is fixed with stainless steel self-tapping screws or stainless steel blind rivets, the rivet spacing of the curved screen should not be greater than 80mm. When the metal Noise Barrier is fixed by welding, the length of the intermittent welding spot should not be less than 8mm, and the spacing between adjacent welding spots should not be greater than 100mm. The screen body made of galvanized steel plate should be polished and partially polished to remove rust at the weld bead, hole making and material cutting edge, and zinc supplement treatment should be done before painting.
The assembly of the metal Noise Barrier screen panel and the back panel, side panels and internal dragons should adopt the snap-on connection method, and should not be fixed by core pulling rivets or intermittent welding. For the metal Noise Barrier screen, it must comply with the above regulations.
