Since the interior of the air membrane building is formed by air pressure, it is relatively empty inside, and general sound-absorbing devices cannot be installed. At present, the sound-absorbing material is generally attached to the membrane body of the air membrane by adhesive spraying, but on the one hand, the adhesive may cause corrosion to the air membrane, and on the other hand, the adhesion effect cannot be guaranteed. A special installation frame is built for the sound-absorbing device: a soldering iron is used to open a hole on the air membrane, and then a rope is pierced through the hole to hang the frame equipped with a sound-absorbing panel to fix the sound-absorbing device on the air membrane.

[0003] The above-mentioned installation method of specially building an installation frame for the sound absorbing device will cause a certain degree of damage to the air membrane when opening the hole, and the installation stability is poor, and it is not convenient to adjust the installation angle of the sound absorbing board frame according to the angle of the air membrane.

[0006] The beneficial effects of the utility model are as follows: the rope threading opening formed by cutting is less destructive to the air film than other through-hole structures, and is not easy to deform the film body around the hole; the hanging plate hung on the connecting rope can be slidably clamped between the sound-absorbing panel support frame and the sound-absorbing panel, and on the one hand, the position of the hanging plate can be slidably adjusted to conveniently adjust the installation position of the sound-absorbing panel, and on the other hand, the hanging plate and the sound-absorbing panel support frame can be quickly assembled, which is convenient for the installation and disassembly of the sound-absorbing panel.

[0007] In order to ensure that the connecting rope can be stably hung on the air film;

[0008] As a further improvement of the above technical solution: the number of the rope threading openings is two in a group and they are arranged parallel to each other.

[0009] The beneficial effect of this improvement is that the operator can pass one end of the connecting rope through one rope threading opening to the outside of the air membrane, and then pass it back to the inside of the air membrane through the other rope threading opening, and then tie the two ends of the connecting rope to the hanging plate, so that the air membrane between the two rope threading openings provides stable support for the connecting rope, ensuring the stability of the connecting rope hanging and facilitating threading.

[0011] As a further improvement of the above technical solution: the hanging plate is a thin structure with a boss, and the front side of one end of the hanging plate is tilted upward.

[0012] The beneficial effect of this improvement is that when the hanging plate is inserted between the sound-absorbing board support frame and the board, the thin material can pass through the gap more conveniently, which is convenient for operation. The other end of the hanging plate is firmly clamped on the outside of the sound-absorbing board support frame, so that the hanging plate can be firmly inserted between the sound-absorbing board support frame and the sound-absorbing board.

[0013] In order to effectively reduce the weight of the sound-absorbing panel support frame;

[0014] As a further improvement of the above technical solution: the sound absorbing board support frame is composed of square tubes.

[0015] The beneficial effects of this improvement are: the sound-absorbing panel support frame has a light weight and a stable structure, can stably support and connect the panels, and provide stable support for the panels.

The number is two in a group and they are arranged in parallel with each other. The operator can pass one end of the connecting rope 4 through one rope threading hole 3 to the outside of the air film 1, and then pass it back to the inside of the air film 1 from the other rope threading hole 3, and then tie the two ends of the connecting rope 4 to the hanging plate 5, so that the air film 1 between the two rope threading holes 3 provides stable support for the connecting rope 4, ensuring the stability of the connecting rope 4. The hanging plate 5 is a thin structure with a boss, and the front side of one end of the hanging plate 5 is tilted upward.
