Description

Technical Field

[0001] The utility model relates to the technical field of curtain wall equipment, in particular to a combined curtain wall with sound insulation and dust prevention. Background Technique

[0002] A curtain wall is the external wall enclosure of a building. It is hung like a curtain, so it is also called a suspended wall. It is a lightweight wall with a decorative effect commonly used in modern large-scale and high-rise buildings. It is composed of a structural frame and inlaid plates and is a building enclosure structure that does not bear the load and action of the main structure.

[0003] In the prior art, the Chinese utility model with the patent number CN209114670U discloses a sound-insulating curtain wall for a music classroom, including an inner curtain wall, a sound-insulating board, and an outer curtain wall. Both ends of the bottom surface of the inner curtain wall are fixedly connected to the wall through connecting frames. The connecting frames are fixedly connected to the wall and the inner curtain wall through first fixing bolts. Multiple second ventilation holes are provided in the middle of the surface of the inner curtain wall. The beneficial effects achieved by the utility model are as follows: Two light inner and outer curtain walls are clamped with each other, which can play a better fixing role. Ventilation holes are provided on the curtain wall to facilitate the smooth air flow between the outside and the inside of the classroom. A sound-insulating board is installed in the ventilation slot between the inner and outer curtain walls, and sound-absorbing cotton is placed on the sound-insulating board, which can well eliminate the influence of external noise on the students inside the classroom. Installing a glass window in the U-shaped card slot can ensure that outdoor light can enter the room and ensure indoor brightness. The entire sound-insulating and ventilating device is installed on the wall through a connecting frame, avoiding instability, making the whole device more convenient to install, with a more beautiful appearance and better sound-insulating effect.

[0004] For the curtain wall designed in the above prior art, in order to better ventilate, ventilation holes are provided on both the inner and outer curtain wall plates for effective ventilation, but no dust prevention mechanism is provided, so that dust and impurities in the air enter between the two curtain walls from the ventilation holes and adhere to the sound-absorbing cotton of the sound-insulating board, which not only affects the sound absorption of the sound-absorbing cotton, but also affects the subsequent ventilation situation with the long-term accumulation of dust. Therefore, it is necessary to optimize and improve to propose a combined curtain wall with sound insulation and dust prevention to solve the above problems. Content of the Utility Model
