Underground parking garage soundproof shed, entrance and exit noise control simple and elegant design. For underground garage noise control, we produce underground garage entrance and exit soundproof sheds, underground garage entrance and exit soundproof shed noise engineering, underground garage anti-slip vibration ramp engineering design and application. Ning Zhiyuan designed the soundproof ceiling for the entrance and exit of the underground garage, and the soundproof canopy for the entrance and exit of the underground garage is simple, elegant and highly adaptable. It can be tailor-made according to the needs of the customer's products and production space. Analysis of Noise Contribution Ratio of Underground Garages
At a time when the real estate industry across the country is heating up, developers are planning reasonable community layouts and apartment types, and paying more attention to the quality of residents’ experience. For those who own one or more cars, the parking problem is The solution is undoubtedly of great concern. The related noise problem in the underground parking garage also emerged and was solved simultaneously. The noise in underground garages is mainly caused by mechanical noise generated by car engines, noise caused by changes in car speed and braking, and low-frequency noise caused by friction between car tires and the ground. The noise source of underground parking garages is mainly caused by vehicle conditions such as starting or changing speed, emergency stops, etc., which produces engine noise and friction noise between tires and the ground. In addition, in order to prevent slipping, the entrance and exit floors are uneven, so the sound produced by the friction between the car engine and tires and the lane Diffraction or even diffraction occurs in the air, causing the noise at the entrance and exit of the project to be radiated to nearby residents to a value of ~dB. Since the entry and exit of vehicles is basically impossible to be continuous and has certain intervals, that is, the noise is highly random. This kind of noise has a serious impact on the environment at night when residents are resting. If things continue like this, it will inevitably lead to resistance to the residents at the entrance and exit, leading to conflicts.
Examples of noise control measures in underground parking garages
. Sound-absorbing ceiling: Install a sound-absorbing ceiling above the entrance and exit of the underground garage. There are two main forms of sound-absorbing ceiling: plate ceiling and glass ceiling. The ceiling is made of stainless steel profiles as the frame, with thick endurance boards laid on the outside and thick microporous plates on the inside.
The price of the panel carport is affordable, and the glass carport has a beautiful appearance and is suitable for use in high-end properties.
.Slope sound-absorbing treatment: The conventional approach is to lay finished high-grade sound-absorbing wall panels, but the cost is high, the reasonable service life is short, and maintenance is inconvenient.
Based on the basic characteristics of the car entrance wall, sound-absorbing treatment is performed on the cement wall at the entrance and exit, and sound-absorbing panels are laid on the walls on both sides of the car (ramp). It adopts a sound-absorbing process structure with Z-shaped keel fixation, a cavity of a certain thickness, waterproof ultra-fine glass wool, and aluminum perforated plates. The sound-absorbing structure is protected by a thick aluminum perforated plate and filled with ultra-fine glass wool felt of a certain volume.
It not only meets the requirements of waterproofing, anti-corrosion and environmental protection, but also has low price and good sound-absorbing effect.
. Floor anti-slip low-frequency vibration-absorbing ramp: Common garage entrances and exits use the ground as a sawtooth wave shape, which can only play a decelerating effect but has no noise reduction effect.
Carry out smoothing treatment on the existing driveway floor, and then build a polygonal and extremely hard, vibration-free and anti-slip driveway on the ground. Based on many years of noise control experience, anti-skid and vibration damping treatments are used at garage entrances and exits, which have greater friction than zigzag ramps. They not only have a decelerating effect, but also can reduce the noise on the slopes by more than dB. Overall, the garage entrances and exits can be improved. The noise dropped by more than dB. At the same time, the ramp also has the characteristics of good aesthetics.
The driveway anti-skid material is made of modified resin, brown corundum, quartz sand, high-grade cement, pigments, etc. in a reasonable proportion. The specially treated lane anti-skid material has good strength, high hardness and large surface resistance. The vehicle will vibrate very little when driving on it, avoiding the noise when passing through the traditional anti-skid lane. With superior waterproof, dustproof, anti-corrosion, weather resistance, mud resistance, direct washability, and beautiful surface effect, it can especially meet the needs of modern properties and is currently the most ideal anti-slip ramp.
