Sound barriers can be classified into the following categories based on their materials: metal sound barriers (metal louvers, metal mesh holes), concrete sound barriers (lightweight concrete, high-strength concrete), PC sound barriers, fiberglass sound barriers, etc.
Features of pinhole composite sound-absorbing aluminum plate: light weight, pollution-free, anti glare, anti-aging, impact resistance, freeze-thaw resistance, stable sound absorption coefficient, moisture resistance, corrosion resistance, easy bending and processing, easy transportation, easy disassembly and maintenance, reasonable cost performance, and can be sprayed with various colors.
The noise reduction of a sound barrier is related to factors such as the frequency of the noise, the height of the barrier, and the distance between the sound source and the receiving point. The noise reduction effect of sound barriers is closely related to the frequency components of the noise.
Sound barriers can be classified into the following categories based on their materials: metal sound barriers (metal louvers, metal mesh holes), concrete sound barriers (lightweight concrete, high-strength concrete), PC sound barriers, fiberglass sound barriers, etc. The PC tempered organic glass panel with a maximum width of 2.7 meters has been officially produced in Wuxi, and the sound barrier factory has successfully installed it, greatly improving the visual and noise reduction effects
Height requirement: The height of rail transit railings should be designed according to ergonomic principles and cannot be set too high or too low. Generally, the height of railings should be between 850mm and 1200mm.
Robustness requirement: The rail transit railing needs to be set on a solid ground or wall to ensure that it will not loosen or fall off. At the same time, plastic or rubber pads need to be installed at the contact between the railing and the ground or wall to protect the ground or wall.
Detail requirements: The appearance design of rail transit railings also needs to comply with ergonomic principles, with a smooth grip to avoid overly rough or sharp edges, while also considering details such as color and shape.
Rail transit railings are fixed equipment set up in subway stations for the convenience of passengers, generally divided into wall railings, entrance railings, and carriage interior railings. The requirements and importance of the installation standards for rail transit railings cannot be ignored. Subway stations should install railings in accordance with relevant regulations to ensure passenger safety and a pleasant journey.
The specifications of the air duct heater are divided into three forms: low temperature, medium temperature, and high temperature. The common structural feature is the use of steel plates to support the electric heating tube to reduce vibration when the fan stops, and an over temperature control device is installed in the junction box.
