Description

Technical Field

[0001] The invention relates to the technical field of building sound absorption treatment, in particular to a sound absorption structure and a sound absorption component. Background Art

[0002] People's requirements for the quality of construction projects are gradually increasing. In addition to meeting safety and usage functions, they pay more attention to the noise prevention effect of buildings. Traditional sound insulation components are plate-like materials. Their production and installation are labor-intensive and time-consuming. They are not easy to remove and modify after installation. They are easily deformed and discolored when heated. They have poor waterproof properties and high maintenance costs in the later stage. The new sound insulation components are membrane-like, usually called sound-absorbing membranes. They have good atomization stability and flexibility. They can be cut into various shapes and are usually pasted or fastened to the surface of walls and other components. However, this way of using sound-absorbing membranes is difficult to fully exert the sound absorption effect. Summary of the invention

[0003] The main purpose of the present invention is to provide a sound absorbing structure, a sound absorbing component and a method for installing the sound absorbing component, so as to solve the technical problem of poor sound absorbing effect of the sound absorbing membrane in the prior art.

[0004] In order to achieve the above object, according to one aspect of the present invention, a sound absorbing structure is provided. The sound absorbing structure comprises:

[0005] A flexible sound-absorbing membrane, wherein the flexible sound-absorbing membrane has a sound-absorbing layer;

[0006] A frame, the shape of which matches the shape of the flexible sound-absorbing membrane, and the frame has a first connection surface connected to the edge of the flexible sound-absorbing membrane;

[0007] A first connecting component connects the flexible sound-absorbing membrane to the first connecting surface.

[0008] It can be seen that by fixing the flexible sound-absorbing membrane through the frame, both sides of the flexible sound-absorbing membrane can play a sound-absorbing role, and it is easy to disassemble and replace, and can be used without being pasted on the surface of a wall or other component. By combining frames of different shapes, sound-absorbing components of different shapes can be obtained.

[0009] Furthermore, the thickness of the flexible sound-absorbing membrane is ≤2000 μm. Thus, the sound-absorbing membrane has good flexibility.

[0010] Furthermore, the frame body also has a second connection surface, the first connection surface and the second connection surface are respectively located at the upper and lower sides of the frame body, and the edge of the flexible sound-absorbing membrane is wound from the second connection surface to the first connection surface; the second connection surface is preferably a curved surface. Thus, on the one hand, the frame body can be hidden behind the sight line to improve the aesthetics, and on the other hand, the contact area between the flexible sound-absorbing membrane and the frame body can be increased, thereby improving the stability of the sound-absorbing structure.

[0011] Furthermore, the first connection assembly includes first bolt assemblies that connect the edge of the flexible sound-absorbing membrane and the first connection surface and are spaced apart, thereby making it easy to use and having a good connection effect.

[0012] Furthermore, the first connection component further comprises a first butt joint surface, and the edge of the flexible sound absorbing membrane is located between the first connection surface and the first butt joint surface. Thus, the edge of the flexible sound absorbing membrane can be subjected to a more uniform force, which helps to improve the flatness of the flexible sound absorbing membrane.

[0013] Furthermore, the edge of the flexible sound-absorbing membrane is bent on the first connection surface to form a two-layer structure, and the flexible sound-absorbing membranes in the two-layer structure are connected to the first connection surface through the first connection component, thereby further improving the connection strength between the flexible sound-absorbing membrane and the frame.

[0014] Furthermore, a partition is provided between the two-layer structure; and / or a support structure for supporting the bend is provided at the bend of the two-layer structure, and the support structure has a curved surface. Thus, the flexible sound-absorbing membrane can be pre-tensioned after the partition and / or the support structure are installed, which helps to improve the flatness of the flexible sound-absorbing membrane in the sound-absorbing structure. The support structures on different first connecting surfaces of each frame can be connected as one, and the partitions on different first connecting surfaces can also be connected as one, so that the tensioning effect is better.

[0015] To achieve the above object, according to another aspect of the present invention, a sound absorbing component is provided, which has a keel frame, the keel frame is provided with the above sound absorbing structure in the empty space, and the sound absorbing structure is connected to the keel frame by a second connecting assembly.

[0016] It can be seen that the sound-absorbing structure of different shapes and colors can be used to form the sound-absorbing component according to the needs of the user. The sound-absorbing component has high strength, can be directly used as a wall, is easy to disassemble and maintain, and has a long service life.

[0017] Furthermore, the second connection assembly includes a first mating surface and a second mating surface perpendicular to each other, the first mating surface is connected to the frame via a second bolt assembly, the second mating surface is connected to the keel frame via a third bolt assembly, and the first mating surface is arranged on one side or both sides of the second mating surface. Thus, the structure is simple and quick installation and removal are convenient.

[0018] Furthermore, the sound absorbing component further comprises a gusset plate and a decorative plate, the gusset plate is connected to the second mating surface via a fourth bolt assembly, and the decorative plate is snap-connected to the gusset plate, thereby the bolt assembly can be hidden in the decorative plate, significantly improving the aesthetics.

[0019] In order to achieve the above object, according to another aspect of the present invention, a method for installing a sound absorbing member is also provided. The method for installing a sound absorbing member comprises the following steps:

[0020] (1) Preparing a sound absorbing structure, comprising the steps of:

[0021] A. Obtaining a flexible sound-absorbing film and a frame having shapes matching each other; the flexible sound-absorbing film having a sound-absorbing layer;

[0023] (2) Erecting the skeleton frame;

[0024] (3) Using a second connecting assembly, the sound absorbing structure is installed on the empty space of the keel frame.

[0025] It can be seen that the installation of the sound absorbing component using the above-mentioned installation method of the sound absorbing component has the advantages of short construction period, simple process, and easy disassembly and maintenance.

[0026] Furthermore, the frame is in a rhombus or triangle shape. That is, the vacant space of the keel frame is in a rhombus or triangle shape. When a rhombus or triangle shape is adopted, the strength of the keel frame is high. The rhombus shape can also be combined with the triangle shape to form a sound-absorbing component of various shapes.

[0027] Furthermore, the thickness of the flexible sound-absorbing membrane is ≤2000 μm. Thus, the sound-absorbing membrane has good flexibility.

[0028] Furthermore, the sound absorbing layer is a high-strength polyester composite coated fabric, so that the flexible sound absorbing membrane has a good sound absorbing effect.

[0029] Furthermore, the frame has a first connecting surface and a second connecting surface, and the first connecting surface and the second connecting surface are respectively located on the upper and lower sides of the frame, and the edge of the flexible sound-absorbing membrane is connected to the first connecting surface through the first connecting component after being wrapped around from the second connecting surface to the first connecting surface; the first connecting component includes a first bolt assembly that connects the edge of the flexible sound-absorbing membrane and the first connecting surface and is distributed at intervals.

[0030] Furthermore, the second connecting surface is a curved surface; a vertical surface is provided between the first connecting surface and the second connecting surface, and the vertical surface is connected to the second connecting component.

[0031] Furthermore, step (1) also includes stretching the flexible sound-absorbing membrane to improve the flatness of the flexible sound-absorbing membrane in the obtained sound-absorbing structure.

[0032] Furthermore, the second connecting assembly includes a first mating surface and a second mating surface that are perpendicular to each other, the first mating surface is connected to the frame via a second bolt assembly, the second mating surface is connected to the keel frame via a third bolt assembly, and the first mating surface is arranged on one side or both sides of the second mating surface.

[0033] Furthermore, the method further includes step (4): installing the gusset plate and the decorative plate in sequence, wherein the gusset plate is connected to the second mating surface via a fourth bolt assembly, and the decorative plate is snap-connected to the gusset plate.

[0034] Furthermore, the sound absorbing member is a suspended ceiling of a large performance venue, such as a stadium, an exhibition center, or an opera house.

Additional aspects and advantages of the present invention will be partially given in the following description, partially become apparent from the following description, or be learned through the practice of the present invention.
