The sound barrier in the residential area is also called the sound insulation wall in the residential area. It is a wall structure. It mainly consists of foundations, barrier plates, steel columns, fasteners, seals, etc. The column is the main support of the sound barrier in the residential area, which needs to be vertical to the ground during installation. The barrier plate is a sound absorption and sound insulation component with very high performance. The main materials include metal sound-absorbing plate, mainly galvanized plate, aluminum plate, louver hole, microporous, wavy, concave and convex type, transparent plate, generally 5+5 laminated glass pc endurance plate, etc., which is usually fixed in the groove of the column with a spring clip, thus forming a complete sound-absorbing wall system.1. Large sound insulation: the average sound insulation shall not be less than 35dB; 2. High sound absorption coefficient: the average sound absorption coefficient shall not be less than 0.84; 3. Weather resistance and durability: the product shall have water resistance, heat resistance, UV resistance, and will not reduce performance or quality abnormality due to the change of rain temperature. The product adopts aluminum alloy coil plate, galvanized coil plate, glass wool, and H steel column surface galvanized coating with anti-corrosion life of more than 15 years. 4. Beauty: multiple colors and shapes can be selected for combination to coordinate with the surrounding environment to form a beautiful landscape. 5. Economy: assembly construction can improve work efficiency, shorten construction time, and save construction costs and labor costs 6. Convenience: It is installed in parallel with other products, easy to maintain and update. 7. Portable: The sound barrier series products have the feature of light weight, which can reduce the load bearing of overhead light rail and elevated road, and can reduce the structural cost. 8. Fire prevention: Ultra-fine glass wool is used, which fully meets the requirements of environmental protection and fire prevention specifications due to its high melting point and non-combustible.
