Suspension type sound absorbing board

Abstract

The invention provides a suspension type sound absorbing board. The suspension type sound absorbing board comprises a sound absorbing board body and a suspending part making the sound absorbing boardbody installed on the inner wall of an inflatable air film gallery, and the sound absorbing board body is installed through the suspending part and a long-strip-shaped mounting hole formed in the inner wall of the inflatable air film gallery; the suspending part comprises a suspending cylinder, a sound absorbing board connector, an adjusting rod, a sealing cover, a mounting connecting rod and an air film connector. The suspension type sound absorbing board is novel in structure and convenience for installation and use, the suspension type sound absorbing board can be installed on the inner wall of the inflatable air film gallery in an inner buckle mounting mode, effective architectural acoustics reconstruction is conducted on the condition that normal use of the air film gallery is not affected, the acoustics environment in the inflatable air film gallery is significantly improved, the use effect of the inflatable air film gallery is improved, and popularization of the suspension typesound absorbing board is helped.

Description

technical field [0001] The invention belongs to the field of acoustic reconstruction equipment, and in particular relates to a suspended sound-absorbing panel suspended on the inner wall of a building. Background technique [0002] With the development of science and technology, various new buildings appear, such as air film building, air film building refers to the use of special architectural membrane materials as the shell, equipped with a set of intelligent electromechanical equipment to provide air inside the air film building Positive pressure, a building structure system that supports the main body of the building. With the development of air-film buildings, there is a new way of building gymnasiums—inflatable air-film pavilions. Since the architectural form of the inflatable dome pavilion is a curved vault, the vault structure is prone to sound focusing and sound reflection, and the reverberation time in the venue is very long, generally as long as 5 seconds, which c...

Problems solved by technology

The adhesives and spraying materials used in this method are chemical substances, which have uncertain corrosiveness to the membrane body of the dome pavilion, and have a great impact on the ambient air inside the dome pavilion; the adsorption stability is difficult to guarantee , there is a possibility of falling off after 1 to 1.5 years; when using a liquid covering material, it is seamlessly adsorbed with the air film itself, and the absorption for the high frequency part is acceptable, but it lacks the regulation of the low frequency

[0006] (3) A metal frame of the same volume is welded in the air film by means of an inner skeleton, and sound-absorbing materials are installed on the metal frame. Due to the large volume of the general air film pavilion, the load capacity of the metal frame is required for a large span. At the same time, the construction cost of the metal frame is relatively high. The most important thing is that if the method is changed, the construction significance of the dome pavilion will be lost.
