Description

Technical Field

[0001] The utility model belongs to the technical field of air film buildings, and in particular relates to an air film structure which can effectively reduce the sound focusing inside the air film. Background Art

[0002] Since the architectural form of the inflatable air dome hall is an arc-shaped vault, the vault structure is prone to sound focusing and sound reflection. The reverberation time in the venue is very long, generally up to 5 seconds, which cannot be used for sound reinforcement, so secondary acoustic reconstruction is needed.

[0003] In the prior art, the utility model patent with the authorization announcement number CN211473614U discloses an air dome that can eliminate sound focusing, including an air dome body, a side wall sound absorbing part, and a top sound focusing eliminating part; the side wall sound absorbing part is installed on the inner side wall of the air dome body; the top sound focusing eliminating part is an arc-shaped and transparent sound wave reverse diffusion structure, which is installed under the transparent top ceiling of the air dome body. On the basis of ensuring the lighting effect inside the air dome, the utility model eliminates the sound focusing caused by the arc-shaped top structure to the maximum extent, ensures that the reverberation time at various places in the air dome can be within the optimal reverberation time range, and effectively solves the problem of top sound focusing.

[0004] The above mechanism has the following problems: 1. After the top sound focusing elimination part absorbs part of the sound waves, the unabsorbed sound waves are directly reflected back to the bottom of the air film building, resulting in limited sound wave elimination effect; 2. A single transparent bright film is hoisted by a hanging rope, and the installation stability is poor. Utility Model Content

[0005] In view of the above problems, the purpose of the utility model is to provide an air membrane structure that effectively reduces the sound focusing inside the air membrane, and to solve the problems that the existing air membrane top silencer structure has limited sound wave elimination effect and poor stability of the silencer membrane installation.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: an air membrane structure that effectively reduces the sound focusing inside the air membrane, including an air membrane, a steel wire rope, a sound-absorbing panel, and a reinforcement rope. A plurality of hanging rings are arranged on the top of the air membrane, one end of the steel wire rope is tied to the hanging ring, and the other end of the steel wire rope is tied to the sound-absorbing panel. The adjacent sound-absorbing panels are staggered up and down, and the reinforcement rope is tied to connect multiple steel wire ropes.

[0007] The beneficial effects of the utility model are as follows: the multiple sound-absorbing panels staggered up and down can make part of the sound waves reflected by the upper sound-absorbing panel be reflected again by the lower sound-absorbing panel, thereby absorbing the sound waves multiple times and effectively improving the sound-absorbing effect; the reinforcement rope can connect the multiple steel wire ropes into one, thereby improving the stability of the hanging of the sound-absorbing panel.

[0008] In order to effectively reflect and absorb the sound waves gathered on the top of the air membrane through the multi-level suspended sound-absorbing panels;

[0009] As a further improvement of the above technical solution: the horizontal distance between adjacent sound absorbing panels is not greater than the length and width of the sound absorbing panels.

[0010] The beneficial effect of this improvement is that after the sound waves are reflected and partially absorbed by the sound-absorbing panel located above, the reflected sound waves are absorbed again by the sound-absorbing panel below and reflected back upward, so that the sound waves undergo multiple reflections, effectively improving the absorption rate of the sound waves and enhancing the elimination effect of the sound waves on the top of the air membrane.

[0011] In order to fully ensure the stability of the installation of multiple sound-absorbing panels;

[0012] As a further improvement of the above technical solution: the reinforcement rope is arranged parallel to the bottom surface of the sound absorbing board.

[0013] The beneficial effect of this improvement is that the reinforcement ropes arranged parallel to the bottom surface of the sound-absorbing panel can form the sound-absorbing panel pulled by multiple steel wire ropes into a whole, thereby reducing the amplitude of the sound-absorbing panel shaking and improving the stability of the sound-absorbing panel hoisting.

[0014] In order to ensure the multi-level sound absorption effect of the sound-absorbing panel;

[0015] As a further improvement of the above technical solution: the bottom portion of the steel wire rope is tied and hung to connect the corners of the sound absorbing board.

[0016] The beneficial effect of this improvement is that the steel wire rope can be tied to the corners of the sound-absorbing panel so that the sound-absorbing panel is evenly pulled by the steel wire rope to ensure the stability of the structure, thereby repeatedly reflecting and absorbing the sound waves gathered on the top of the air film in a stable shape.

[0017] In order to effectively reduce the wear of the wire rope on the lifting ring when the wire rope is shaken by the sound absorbing board;

[0018] As a further improvement of the above technical solution: the hanging ring is a D-shaped ring structure.

[0019] The beneficial effect of this improvement is that the arc section of the D-shaped ring can reduce the wear of the wire rope when it slides relative to the lifting ring.

[0020] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0025] Embodiment 1:

[0026] like Figure 1 —2 shows: an air membrane structure which effectively reduces the sound focusing inside the air membrane, comprising an air membrane 1, a steel wire rope 2, a sound absorbing panel 4, and a reinforcement rope 5. A plurality of lifting rings 3 are arranged on the top of the air membrane 1, one end of the steel wire rope 2 is tied to the lifting ring 3, and the other end of the steel wire rope 2 is tied to the sound absorbing panel 4. Adjacent sound absorbing panels 4 are staggered up and down, and the reinforcement rope 5 is tied to connect a plurality of steel wire ropes 2. The plurality of sound absorbing panels 4 staggered up and down can make part of the sound waves reflected by the upper sound absorbing panel 4 be reflected again by the lower sound absorbing panel 4, thereby absorbing the sound waves multiple times, effectively improving the sound-absorbing effect; the reinforcement rope 5 can connect the plurality of steel wire ropes 2 into one body, improve the stability of the hanging of the sound absorbing panel 4, and the horizontal distance between adjacent sound absorbing panels 4 is not greater than the length and width of the sound absorbing panel 4. After the sound waves are reflected and absorbed by the upper sound absorbing panel 4, the reflected sound The sound waves are absorbed by the sound-absorbing panel 4 below and reflected back upward again, so that the sound waves are reflected in multiple channels, effectively improving the absorption rate of sound waves and enhancing the elimination effect of sound waves on the top of the air membrane 1. The reinforcement rope 5 is arranged parallel to the bottom surface of the sound-absorbing panel 4. The reinforcement rope 5 arranged parallel to the bottom surface of the sound-absorbing panel 4 can form the sound-absorbing panel 4 pulled by multiple steel wire ropes 2 into a whole, thereby reducing the shaking amplitude of the sound-absorbing panel 4 and improving the stability of the sound-absorbing panel 4 hoisting. The bottom part of the steel wire rope 2 is tied and hung at the corners of the sound-absorbing panel 4. The steel wire rope 2 can be tied and connected to the corners of the sound-absorbing panel 4, so that the sound-absorbing panel 4 is evenly pulled by the steel wire rope 2 to ensure the stability of the structure, thereby repeatedly reflecting and absorbing the sound waves gathered on the top of the air membrane 1 in a stable shape. The lifting ring 3 is a D-shaped ring structure, and the arc section of the D-shaped ring can reduce the wear of the steel wire rope 2 when it slides relative to the lifting ring 3.

[0027] The working principle of the present technical solution is as follows: after part of the sound waves in the air membrane 1 gathers at the top of the air membrane 1, part of the sound waves are directly reflected downward by the sound-absorbing panel 4 installed at a low point and partially absorbed, and the other part of the sound waves is transmitted to the sound-absorbing panel 4 located at a high point. After being reflected and partially absorbed by the sound-absorbing panel 4, the reflected sound waves are again absorbed by the sound-absorbing panel 4 below and reflected back upward, so that the sound waves undergo multiple reflections, effectively improving the absorption rate of the sound waves and enhancing the elimination effect of the sound waves on the top of the air membrane 1.
