Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a decorative low-noise air shaft. Background Art

[0002] Buildings with large underground spaces, such as subways, cross-river tunnels, and high-rise buildings, are all equipped with ventilation shafts. The ventilation shaft is connected to the supply and exhaust fans in the underground space to serve as a functional building for supplying and exhausting air in the underground space. Since the supply and exhaust fans generate a certain amount of noise when in operation, the noise is transmitted to the outside through the vents of the shaft and affects the surrounding environment. In addition, these underground spaces are often arranged in areas where people are relatively concentrated. In addition to requiring low noise from the wind shaft, there are often decoration requirements. The outer surface of the wind shaft from the entire floor surface is required to meet the decoration requirements of the environment in the area, and the equipment in the ventilation shaft and its connected pipes should not be clearly visible to the naked eye.

[0003] At present, there are aluminum square tubes or ventilation curtain walls on the market to block and enclose ventilation shafts, which solve the problems of ventilation and decoration, but have no noise reduction effect. One is to set ventilation and noise reduction shutters at the vents of the ventilation shaft to solve the problems of ventilation and noise pollution, but these noise reduction facilities are often not coordinated with the regional environment and cannot solve the decorative problem; the third is to combine the first two, not only to do noise reduction treatment, but also to decorate the outside of the noise reduction facilities, but it causes double investment, and the arrangement of the noise reduction sheets of the ventilation and noise reduction shutters cannot be consistent with the decorative materials, making the decorative layer an obstacle to the airflow vents, thereby greatly increasing the ventilation resistance and possibly affecting the normal operation of the equipment. The fourth is to use a folded plate ventilation and noise reduction curtain wall, which has decorative, ventilation and noise reduction functions, but it can only solve the decorative treatment at the vents of the ventilation shaft, and cannot solve the decorative treatment of the shaft wall and other areas.
