Description

Technical Field

[0001] This utility model relates to the field of soundproof wall panel technology, and in particular to a gypsum-based soundproof wall panel. Background Technology

[0002] With the acceleration of urbanization and the increase in building density, noise pollution has become increasingly serious. In particular, low- and medium-frequency noise (such as traffic noise and mechanical equipment vibration) has a significant impact on indoor environmental comfort due to its strong penetrability and slow attenuation.

[0003] Traditional gypsum-based wall panels, as building partition materials, have certain sound insulation properties, but their sound insulation mechanism is simple, mainly relying on material density or simple stacking of sound-absorbing layers. They are difficult to effectively block low and medium frequency noise, resulting in poor sound insulation and failing to meet the increasingly demanding requirements for acoustic environments. Utility Model Content

[0004] In view of the fact that existing sound insulation mainly relies on material density or simply stacking sound-absorbing layers, it is difficult to effectively block low- and mid-frequency noise and the sound insulation effect is poor, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a gypsum-based soundproof wall panel, which aims to effectively isolate low and medium frequency noise through multiple sound insulation measures.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a gypsum-based sound insulation wall panel, including a wall panel body and a sealing frame including the four sides of the wall panel body;

[0007] The wall panel body includes two core panels installed inside the sealed frame. Sound-absorbing components are installed on the opposite sides of the two core panels. A gypsum board is fixed to the end face of the sound-absorbing component away from the core panel, and the gypsum board is flush with the end face of the sealed frame.

[0008] As an improved technical solution, a vacuum cavity is formed between the two core plates and the inner wall surface of the sealing frame, and the core plates are metal plates.

[0009] As an improved technical solution, arc-shaped reflectors are installed on both sides inside the vacuum cavity, and the two reflectors are arranged in a relative and staggered manner.

[0010] As an improved technical solution, the sound-absorbing component includes a damping layer fixed on the side of the core board away from the reflector. The damping layer is a sound-insulating damping adhesive. Sound-absorbing cotton is fixed to the end face of the damping layer away from the core board, and a sound-insulating board is fixed to the end face of the sound-absorbing cotton away from the damping layer.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are:

[0012] This invention utilizes the mass effect and rigidity of the metal plate, the sound bridge blocking effect of the vacuum cavity, the sound wave scattering and guiding effect of the arc-shaped reflector, the vibration damping energy dissipation effect of the sound-insulating damping adhesive, and the sound absorption conversion effect of the sound-absorbing material to form a multi-layered synergistic sound barrier. This barrier covers different paths and frequencies of sound wave propagation, effectively suppressing the energy transfer of mid- and low-frequency sound waves. Furthermore, the symmetrically arranged sound insulation measures allow for simultaneous sound insulation treatment from both sides, resulting in excellent sound insulation performance.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example

[0020] Reference Figs. 1-3 This is the first embodiment of the present utility model, which provides a gypsum-based sound insulation wall panel. This gypsum-based sound insulation wall panel includes a wall panel body 1 and a sealing frame 2 included on the four sides of the wall panel body 1.

[0021] The wall panel body 1 includes two core panels 3 installed inside the sealing frame 2. The core panels 3 are metal plates, providing high surface density and rigidity, enhancing the mass law effect, and effectively blocking mid-frequency sound waves. Sound-absorbing components 4 are installed on the opposite sides of the two core panels 3. A gypsum board 5 is fixed to the end face of the sound-absorbing component 4 away from the core panel 3, and the gypsum board 5 is flush with the end face of the sealing frame 2.

[0022] A vacuum cavity 6 is formed between the inner walls of the two core plates 3 and the sealing frame 2. The core plates 3 are metal plates. The formation of the vacuum cavity 6 greatly weakens the direct transmission path of sound waves through the air medium and solid sound bridge, which is particularly important for isolating low-frequency noise.

[0023] By utilizing the mass effect and rigidity of the metal plate, the sound bridge blocking effect of the vacuum cavity 6, the sound wave scattering and guiding effect of the arc-shaped reflector 7, the vibration damping energy dissipation effect of the sound insulation damping adhesive, and the sound absorption conversion effect of the sound-absorbing material, a multi-layered synergistic sound barrier is formed, covering different paths and frequencies of sound wave propagation. This effectively suppresses the energy transfer of mid-to-low frequency sound waves. Furthermore, the symmetrically arranged sound insulation measures allow for simultaneous sound insulation treatment from both sides, resulting in excellent sound insulation performance.

[0024] Arc-shaped reflectors 7 are installed on both sides inside the vacuum cavity 6, and the reflectors 7 are set in a relative and staggered manner. The setting of the reflectors 7 changes the direction of sound wave propagation, increases the reflection path and attenuation distance of the sound wave in the vacuum cavity 6.

[0025] The sound-absorbing component 4 includes a damping layer 41 fixed on the side of the core plate 3 away from the reflector plate 7. The damping layer 41 is a sound-insulating damping adhesive. A sound-absorbing cotton 42 is fixed on the end face of the damping layer 41 away from the core plate 3. A sound-insulating plate 43 is fixed on the end face of the sound-absorbing cotton 42 away from the damping layer 41. The sound-insulating damping adhesive of the damping layer 41 is in contact with the core plate 3, effectively suppressing the vibration of the metal plate caused by sound wave excitation, converting sound energy into heat energy dissipation, and significantly reducing the transmission of mid- and low-frequency sound. The setting of the sound-absorbing cotton 42 and the sound-insulating plate 43 mainly absorbs mid- and high-frequency sound waves, reducing sound energy accumulation and reflection.

[0026] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
