Description

Technical Field

[0001] The utility model relates to the field of sound insulation decorative boards, and specifically relates to a building sound insulation decorative board. Background Art

[0002] A sound insulation decorative board is a board that functions for sound insulation and can be used for decoration. It is classified into building sound insulation and structure sound insulation. A sound insulation board refers to a material that can isolate acoustic signals such as noise and sound waves. Sound insulation boards are widely used in fields such as construction, automobiles, and machinery, and can effectively reduce the interference of external environmental noise on the interior or equipment, improving the comfort and quietness of the environment.

[0003] Sound insulation boards are often used in interior decoration. A sound insulation board is composed of a base material, an isolation layer, a surface layer, and other auxiliary materials. Among them, the isolation layer is the core part of the sound insulation board and is mainly composed of sound-absorbing materials and reflective materials.

[0004] Due to the relatively small density of the sound insulation holes on the above-mentioned common sound insulation boards for interior decoration, the sound insulation performance of the sound insulation board is poor. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a building sound insulation decorative board to solve the technical problems mentioned in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A sound insulation decorative board and a decorative panel are included. The sound insulation decorative board is in a plate shape, and the sound insulation decorative board includes a decorative panel, a sound-absorbing layer, a sound-insulating layer, and a reflective layer. The outer wall of the decorative panel is fixedly connected to the sound-absorbing layer, and the sound-insulating layer is fixedly installed on the outer wall of the sound-absorbing layer. And the reflective layer is fixedly installed on the outer wall of the sound-insulating layer. One side of the decorative panel is provided with a sound-absorbing layer, and the other side of the sound-absorbing layer is provided with a sound-insulating layer. The other side of the sound-insulating layer is provided with a reflective layer, and the other side of the reflective layer is fixedly installed on a wall. The outer wall of the sound-absorbing layer is provided with sound-absorbing holes, and the outer wall of the sound-insulating layer is provided with through grooves. The outer wall of the reflective layer is provided with corrugated grooves.

[0007] By adopting the above technical solution, while sound waves are absorbed and dispersed by the sound-absorbing holes, part of the sound waves are dispersed by the through grooves, and the remaining part of the sound waves are reflected by the corrugated grooves. After further reflection, the sound waves are finally isolated.

[0008] Further, multiple groups of the sound-absorbing holes are equidistantly arranged on the outer wall of the sound-absorbing layer, and the sound-absorbing layer is a glass wool board.

[0009] By adopting the above technical solution, the sound-absorbing effect of the sound-absorbing layer is enhanced, so that the sound waves are absorbed more evenly, and at the same time, it is ensured that the sound waves can be further transmitted to the sound-insulating layer.

[0010] Further, multiple groups of through slots are arranged at equal intervals on the outer wall of the sound insulation layer, and the length of the through slots is less than the length of the sound insulation layer. The sound insulation layer is a sound insulation felt board.

[0011] By adopting the above technical solution, the sound insulation effect of the sound insulation layer is enhanced, so that sound waves are further isolated, and the interference of sound waves is effectively reduced.

[0012] Further, multiple groups of corrugated slots are arranged at equal intervals on the outer wall of the reflection layer, and the depth of the corrugated slots is half of the thickness of the reflection layer. The reflection layer is a fiberglass reinforced plastic plate.

[0013] By adopting the above technical solution, while isolating sound waves, the corrugated slots reflect the sound waves, weakening the energy of the sound waves and further reducing the transmission of sound waves.

[0014] Further, two groups of teeth are symmetrically installed in the sound absorption holes.

[0015] By adopting the above technical solution, the absorption and interference of sound waves by the sound absorption holes are enhanced, and the transmission range of sound waves is reduced.

[0016] Further, the cross-section of the through slot is designed in an inverted V-shaped structure, and the horizontal plane where the opening of the through slot is located is lower than the horizontal plane where the inner top angle of the through slot is located.

[0017] By adopting the above technical solution, while part of the sound waves are isolated, they are blocked, and the transmission and interference of sound waves are further reduced.

[0018] Further, multiple groups of convex balls are arranged in the corrugated slots, and the convex balls are designed in a semi-spherical structure.

[0019] By adopting the above technical solution, the reflection of sound waves is enhanced, so that the sound waves are further reflected, thereby effectively reducing the interference of sound waves and improving the comfort and quietness of the environment.

[0020] In summary, the main beneficial effects of the present utility model are as follows:

[0021] The present utility model is provided with a sound absorption board, a sound insulation board and a reflection layer.

Under the action of the through slots of the sound insulation board, due to the inverted V-shaped design, the sound waves are further scattered and transmitted to the reflection layer. The corrugated slots of the reflection layer reflect the sound waves, and at the same time, the convex balls in the corrugated slots reflect the sound waves, so that the sound waves are isolated, and the interference of external environmental noise on the interior is effectively reduced, and the comfort and quietness of the environment are improved.

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0028] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0029] A building sound-insulating decorative board, as Figure 1 - Figure 4 shown, includes a sound-insulating decorative board 1 and a decorative panel 2. The sound-insulating decorative board 1 is in a plate shape, and the sound-insulating decorative board 1 includes a decorative panel 2, a sound-absorbing layer 3, a sound-insulating layer 5, and a reflection layer 7. The outer wall of the decorative panel 2 is fixedly connected to the sound-absorbing layer 3, and the outer wall of the sound-absorbing layer 3 is fixedly installed with the sound-insulating layer 5, and the outer wall of the sound-insulating layer 5 is fixedly installed with the reflection layer 7. One side of the decorative panel 2 is provided with the sound-absorbing layer 3, and the other side of the sound-absorbing layer 3 is provided with the sound-insulating layer 5. The other side of the sound-insulating layer 5 is provided with the reflection layer 7, and the other side of the reflection layer 7 is fixedly installed with the wall 10, so that when sound waves are transmitted, they can pass through the sound-absorbing layer 3 smoothly, and then part of the sound waves are absorbed by the sound-absorbing layer 3. When passing through the sound-insulating layer 5, due to the effect of the through slots 6, the sound waves are scattered and propagated, and then part of the sound waves are isolated. The outer wall of the sound-absorbing layer 3 is provided with sound-absorbing holes 4, and the outer wall of the sound-insulating layer 5 is provided with through slots 6. The outer wall of the reflection layer 7 is provided with corrugated slots 8, so that while the sound waves are absorbed and scattered by the sound-absorbing holes 4, part of the sound waves are scattered by the through slots 6, and the remaining part of the sound waves are reflected by the corrugated slots 8. After further reflection, the sound waves are finally isolated.

[0030] Please refer to Figure 1 and Figure 2 , multiple groups of sound-absorbing holes 4 are arranged at equal intervals on the outer wall of the sound-absorbing layer 3, and the sound-absorbing layer 3 is a glass wool board, which enhances the sound-absorbing effect of the sound-absorbing layer 3, makes the sound waves be absorbed more evenly, and at the same time ensures that the sound waves can be further transmitted to the sound-insulating layer 5.

[0031] Please refer to Figure 1 and Figure 3 where multiple groups of through slots 6 are equidistantly arranged on the outer wall of the sound insulation layer 5, and the length of the through slots 6 is less than the length of the sound insulation layer 5. The sound insulation layer 5 is a sound insulation felt board, enhancing the sound insulation effect of the sound insulation layer 5, so that sound waves are further isolated, effectively reducing the interference of sound waves.

[0032] Please refer to Figure 1 and Figure 4 where multiple groups of corrugated slots 8 are equidistantly arranged on the outer wall of the reflection layer 7, and the depth of the corrugated slots 8 is half of the thickness of the reflection layer 7. The reflection layer 7 is a fiberglass plate. While isolating sound waves, the corrugated slots 8 reflect the sound waves, weakening the energy of the sound waves and further reducing the transmission of sound waves.

[0033] Please refer to Figure 1 where two groups of teeth 41 are symmetrically installed in the sound absorption holes 4, enhancing the absorption and interference of sound waves by the sound absorption holes 4 and reducing the transmission range of sound waves.

[0034] Please refer to Figure 1 and Figure 3 where the cross-section of the through slot 6 is designed in an inverted V-shaped structure, and the horizontal plane where the opening of the through slot 6 is located is lower than the horizontal plane where the inner top angle of the through slot 6 is located. The inverted V-shaped structure design of the through slot 6 blocks sound waves while partially isolating them, further reducing the transmission and interference of sound waves.

[0035] Please refer to Figure 1 and Figure 4 where multiple groups of convex balls 9 are arranged in the corrugated slots 8, and the convex balls 9 are designed in a semi-spherical structure. While the corrugated slots 8 reflect sound waves, the convex balls 9 enhance the reflection of sound waves, so that sound waves are further reflected, effectively reducing the interference of sound waves and improving the comfort and quietness of the environment.

[0036] The working principle of the present utility model is as follows: when sound waves are transmitted to the sound absorption layer 3, the sound absorption holes 4 of the sound absorption layer 3 absorb most of the sound waves, and the sound waves are dispersedly transmitted to the sound insulation layer 5. Under the action of the through slots 6 on the sound insulation layer 5, the sound waves are further dispersedly transmitted to the reflection layer 7. The reflection layer 7 receives the sound waves, and the corrugated slots 8 on it disperse the sound waves and then reflect the sound waves, effectively suppressing the propagation of sound and vibration.

[0037] Although embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not contribute creatively to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
