Description

Technical Field

[0001] This utility model relates to the technical field of wall structural components, specifically to a noise-reducing and heat-insulating wall structural component. Background Technology

[0002] With the upgrading of building functional requirements, wall structural components have evolved from simple decoration to multi-functional integration of "decoration, sound absorption, and heat insulation." Currently, mainstream wall materials achieve decorative effects through material simulation (such as imitation wood and stone), achieve sound absorption and noise reduction through porous materials or resonant structures, and achieve heat insulation and energy saving through composite insulation layers. They are widely used in residential, office, and other scenarios, beautifying spaces while improving acoustic comfort and building energy efficiency, and possessing significant practical value.

[0003] However, existing multifunctional wall structural components have obvious shortcomings: on the one hand, traditional wooden sound-absorbing materials rely on fiber pores for sound absorption, but their fiber density is easily affected by the material and processing technology, resulting in unstable sound absorption performance and difficulty in controlling volume data; on the other hand, if materials such as glass fiber cotton are used to achieve efficient sound absorption, complex composite processes and high-purity raw materials are required, which significantly increases production costs, and some fiber materials have problems such as insufficient environmental protection and easy growth of mold. Utility Model Content

[0004] The purpose of this application is to provide a noise-reducing and heat-insulating wall structure to solve the problem of unstable sound absorption performance of existing noise-reducing and heat-insulating wall structures.

[0005] One embodiment of this utility model provides a noise-reducing and heat-insulating wall structure, including a hollow structure and a covering structure. The covering structure is installed on the hollow structure and has a plurality of sound-absorbing holes. The hollow structure includes a structural frame and a cavity structure disposed in the structural frame. One side of the cavity structure is covered by the covering structure, and the other side is covered with a sound-absorbing layer. The sound-absorbing layer is installed on the structural frame. The hollow structure also includes an installation component, which is connected to the external keel by a mortise and tenon structure. The installation component and the sound-absorbing layer form a sound-absorbing cavity with the external keel.

[0006] It should be noted that the mortise and tenon structure can be achieved by setting tenon structures on the mounting components and mortise structures on the external keel, or by setting mortise structures on the mounting components and tenon structures on the external keel; in addition, the sound-absorbing layer can be a thin felt layer, specifically a fiberglass felt or similar material. Additionally, regardless of the form, the edges of the mounting components are provided with mounting frames. The width of the mounting frames is the same as that of the mortise and tenon structure. That is, when the mortise and tenon structure is fully installed, the mounting frames fit against the keel, so that the mounting components and the sound-absorbing layer together with the keel form a sound-absorbing cavity.

[0007] In addition, the material of this utility model can be modified plastic. Modified plastic has both good structural strength and processing plasticity. It can be injection molded into a hollow structural component with a preset geometric shape in one step. While meeting the requirements of uniform wall thickness, it can avoid the fluctuation of sound absorption performance caused by uneven fiber distribution in traditional wood materials. Modified plastic itself has certain weather resistance, moisture resistance and flame retardancy, which can adapt to the wall use needs in different environments. It can also form a material synergy with the low elasticity soft material and carbon-containing medium-foamed microporous material internally coated below.

[0008] It should be noted that the sound-absorbing holes are used to guide sound waves into the sound-absorbing cavity. Low-frequency sound waves resonate with the sound-absorbing layer and cavity wall inside the sound-absorbing cavity, and the low-frequency vibration is canceled out through energy conversion. High-frequency sound waves are absorbed by the porous structure of the sound-absorbing layer when passing through the sound-absorbing holes, and the attenuation of high-frequency sound waves is achieved through frictional dissipation.

[0009] It should also be noted that in actual use, this utility model can be directly installed on the external keel or on a wall installation structure of the same type with a corresponding mortise and tenon structure through the installation components. On the other hand, it can also be directly installed on wall tiles or other similar wall components through the installation components.

[0010] In this solution, the structure of sound-absorbing holes, sound-absorbing layers, and sound-absorbing cavities on the covering structure can, on the one hand, cancel low-frequency vibrations and absorb high-frequency sound waves, solving the problem of unstable sound absorption performance caused by the uneven structure of traditional materials; on the other hand, the production cost of sound-absorbing holes, sound-absorbing layers, and sound-absorbing cavities is lower than that of existing high-efficiency sound-absorbing materials, reducing the overall production cost while ensuring the sound absorption effect, and achieving a balance between sound absorption performance and production cost.

[0011] In one embodiment, the mounting component is provided with a mortise structure, which is used to connect with a tenon structure on the external keel.

[0012] It should be noted that in actual installation, mortise and tenon structures are usually used in conjunction with locating pins or environmentally friendly adhesives; locating pins are used to help calibrate the assembly position of the mortise and tenon to ensure installation accuracy; adhesives form a micro-seal on the mating surfaces of the mortise and tenon, further enhancing the stability of the connection, while preventing additional sound bridge transmission between the structural components and the keel due to gaps.

[0013] In this solution, a stable and rigid connection between the mounting components and the keel can be achieved by creating mortise structures on the mounting components and connecting them with the tenon structures of the external keel.

[0014] In one embodiment, a sound-absorbing groove is provided on the structural frame, and the position of the sound-absorbing hole corresponds to the position of the sound-absorbing groove.

[0015] In one embodiment, the sound-absorbing holes, corresponding to the position of the sound-absorbing groove, are obliquely formed in the covering structure.

[0016] It should be noted that the sound-absorbing holes corresponding to the position of the sound-absorbing channel are obliquely opened in the covering structure. Specifically, the inner port of the oblique sound-absorbing hole faces the channel wall of the sound-absorbing channel, so that the sound waves can directly act on the channel wall after entering through the sound-absorbing hole, forming a targeted reflection and resonance path, thereby enhancing the resonance cancellation effect of noise.

[0017] In this solution, by creating sound-absorbing channels on the structural frame corresponding to the positions of the sound-absorbing holes, and by opening the sound-absorbing holes at an angle with their inner ports facing the channel wall, sound waves can be transmitted obliquely through the sound-absorbing holes to the sound-absorbing channels, forming directional resonance with the channel wall to enhance the cancellation efficiency of low-frequency noise. Through the corresponding structure of the sound-absorbing holes and the sound-absorbing channels, the propagation path of sound waves in the cavity structure can be extended, and the oblique design allows high-frequency sound waves to contact the sound-absorbing layer more fully, improving the high-frequency absorption effect.

[0018] In one embodiment, the sound-absorbing hole includes a low-frequency hole structure, which is a tapered hole with a diameter that gradually increases from the outside to the inside.

[0019] In one embodiment, the aperture spacing between each of the low-frequency aperture structures is 8-10 mm.

[0020] In this scheme, by adopting a tapered low-frequency aperture structure with the aperture gradually increasing from the outside to the inside, the incident sound wave can be reflected and superimposed within the aperture by utilizing the gradually expanding structure of the tapered aperture, thereby enhancing the resonance absorption effect of low-frequency sound waves and effectively solving the problem of insufficient low-frequency noise absorption capacity of traditional straight aperture structures. By controlling the aperture spacing to 8-10mm, the weakening of the sound wave interference effect due to excessively small aperture spacing can be avoided, thus enabling the low-frequency aperture structure to form a stable sound absorption frequency band in a wider low-frequency range.

[0021] In one embodiment, the sound-absorbing hole includes a high-frequency hole structure, which is a cylindrical straight hole.

[0022] In one embodiment, the aperture spacing between each of the high-frequency aperture structures is 15-20 mm.

[0023] In this scheme, by setting a high-frequency hole structure with cylindrical straight holes, the structural characteristics of the cylindrical straight holes can be utilized to allow high-frequency sound waves to be directly and smoothly transmitted into the sound-absorbing layer. By setting the hole spacing between each high-frequency hole structure to 15-20mm, the mutual interference of sound waves caused by excessively small hole spacing can be avoided, ensuring that the high-frequency hole structure can stably perform its absorption function of high-frequency sound waves.

[0024] In one embodiment, the structural frame and the interior of the covering structure are coated with a functional material.

[0025] It should be noted that functional materials can include two categories: one is a 2-3mm low-elasticity soft material coated on the inner wall of the hollow structure, which has fireproof, shockproof, and sound insulation properties and is harmless to the human body. Specifically, flame-retardant butyl rubber, neoprene rubber, and similar materials can be selected; the other is a 1-3mm carbon-containing medium-foamed microporous material coated on the inner wall of the hollow structure, which has flame-retardant, heat-insulating, and sterilization functions. Specifically, carbon-containing flame-retardant polyurethane foam can be selected; the interior of the encapsulated structure can be coated with at least two functional materials with matching properties, including the above-mentioned materials, to form a synergistic effect and improve the overall comprehensive performance.

[0026] In this solution, by applying the aforementioned functional materials to the structural frame and the interior of the covering structure, on the one hand, the fire-resistant, earthquake-resistant, and sound-insulating properties of the low-elasticity soft material can be utilized to enhance the overall stability and sound insulation of the structure. Combined with structures such as sound-absorbing holes and sound-absorbing cavities, the noise blocking and absorption effect can be further strengthened. On the other hand, the flame-retardant, heat-insulating, and sterilizing functions of the carbon-containing foamed microporous material can be utilized to improve the fire safety level of the structural components and reduce heat transfer to achieve a heat insulation effect.

[0027] In one embodiment, the outer surface of the covering structure is covered with a flexible material layer.

[0028] It should be noted that the flexible material layer can be made of different flexible materials such as wood, fabric, stone, and metal produced from plastic resin film, in order to simulate the visual texture and surface texture of the corresponding materials.

[0029] In this solution, by covering the outer surface of the encapsulated structure with the aforementioned flexible material layer, on the one hand, the wall structural components can achieve a variety of decorative appearances while possessing functions such as sound absorption, heat insulation, and fire resistance, thus meeting the aesthetic needs of different scenarios and achieving a fusion of functionality and decoration; on the other hand, the flexible material layer made of plastic resin film is lightweight and thin with good adhesion, which can tightly encapsulate the structural surface, protecting the encapsulated structure from external wear and tear without adding extra structural thickness, and is also lower in cost than natural decorative materials, thereby improving the decorative effect while further balancing comprehensive performance and production costs.

[0036] Please refer to Figures 1-9 One embodiment of this utility model provides a noise-reducing and heat-insulating wall structure, including a hollow structure 1 and a covering structure 2. The covering structure 2 is installed on the hollow structure 1 and has a plurality of sound-absorbing holes 6. The hollow structure 1 includes a structural frame 11 and a cavity structure 14 disposed in the structural frame 11. One side of the cavity structure 14 is covered by the covering structure 2, and the other side is covered by a sound-absorbing layer 13. The sound-absorbing layer 13 is installed on the structural frame 11. The hollow structure 1 also includes an installation component 12, which is connected to the external keel by a mortise and tenon structure. The installation component 12 and the sound-absorbing layer 13 form a sound-absorbing cavity with the external keel.

[0037] It should be noted that the mortise and tenon structure can be achieved by setting a tenon structure 4 on the mounting component 12 and a mortise structure 3 on the external keel, or by setting a mortise structure 3 on the mounting component 12 and a tenon structure 4 on the external keel, so as to install the mounting component 12 and the external keel; in addition, the sound-absorbing layer 13 can be a thin felt layer, specifically a fiberglass felt or similar material. Additionally, regardless of the form, the mounting component 12 is provided with a mounting frame on its edge. The width of the mounting frame is the same as that of the mortise and tenon structure. That is, when the mortise and tenon structure is fully installed, the mounting frame fits against the keel, so that the mounting component 12 and the sound-absorbing layer 13 together with the keel form a sound-absorbing cavity.

[0038] In addition, the material of this utility model can be modified plastic. Modified plastic has both good structural strength and processing plasticity. It can be injection molded into a hollow structural component with a preset geometric shape in one step. While meeting the requirements of uniform wall thickness, it can avoid the fluctuation of sound absorption performance caused by uneven fiber distribution in traditional wood materials. Modified plastic itself has certain weather resistance, moisture resistance and flame retardancy, which can adapt to the wall use needs in different environments. It can also form a material synergy with the low elasticity soft material and carbon-containing medium-foamed microporous material internally coated below.

[0039] It should be noted that the sound-absorbing hole 6 is used to guide sound waves into the sound-absorbing cavity. Low-frequency sound waves resonate with the sound-absorbing layer 13 and the cavity wall in the sound-absorbing cavity, and the low-frequency vibration is canceled out through energy conversion. High-frequency sound waves are absorbed by the porous structure of the sound-absorbing layer 13 when passing through the sound-absorbing hole 6, and the high-frequency sound waves are attenuated through frictional dissipation.

[0040] It should also be noted that, in actual use, this utility model can be directly installed on the external keel through the installation component 12, or on the same type of wall installation structure with corresponding mortise and tenon structure. On the other hand, it can also be directly installed on wall tiles or other similar wall components through the installation component 12.

[0041] In this embodiment, the structure of the sound-absorbing holes 6, the sound-absorbing layer 13, and the sound-absorbing cavity on the covering structure 2 can, on the one hand, cancel low-frequency vibrations and absorb high-frequency sound waves, solving the problem of unstable sound absorption performance caused by the uneven structure of traditional materials; on the other hand, the production cost of the sound-absorbing holes 6, the sound-absorbing layer 13, and the sound-absorbing cavity is lower than that of existing high-efficiency sound-absorbing materials, reducing the overall production cost while ensuring the sound absorption effect, and achieving a balance between sound absorption performance and production cost.

[0042] In one embodiment, the mounting component 12 is provided with a mortise structure 3, which is used to connect with the tenon structure 4 on the external keel.

[0043] It should be noted that in actual installation, mortise and tenon structures are usually used in conjunction with locating pins or environmentally friendly adhesives; locating pins are used to help calibrate the assembly position of the mortise and tenon to ensure installation accuracy; adhesives form a micro-seal on the mating surfaces of the mortise and tenon, further enhancing the stability of the connection, while preventing additional sound bridge transmission between the structural components and the keel due to gaps.

[0044] In this embodiment, by opening a mortise structure 3 on the mounting component 12 and connecting it with the tenon structure 4 of the external keel, a stable and rigid connection between the mounting component 12 and the keel can be achieved.

[0045] In one embodiment, a sound-absorbing groove 5 is provided on the structural frame 11, and the position of the sound-absorbing hole 6 corresponds to the position of the sound-absorbing groove 5.

[0046] In one embodiment, the sound-absorbing hole 6, which corresponds to the position of the sound-absorbing groove 5, is obliquely opened in the covering structure 2.

[0047] It should be noted that the sound-absorbing hole 6, which corresponds to the position of the sound-absorbing channel 5, is obliquely opened in the covering structure 2. Specifically, the inner port of the oblique sound-absorbing hole 6 faces the channel wall of the sound-absorbing channel 5, so that the sound wave can directly act on the channel wall after entering through the sound-absorbing hole 6, forming a targeted reflection and resonance path, thereby enhancing the resonance cancellation effect of noise.

[0048] In this embodiment, by opening a sound-absorbing groove 5 on the structural frame 11 corresponding to the position of the sound-absorbing hole 6, and opening the sound-absorbing hole 6 obliquely with its inner port facing the groove wall of the sound-absorbing groove 5, the sound waves can be obliquely transmitted through the sound-absorbing hole 6 to the sound-absorbing groove 5, forming a directional resonance with the groove wall, thereby enhancing the cancellation efficiency of low-frequency noise; through the corresponding structure of the sound-absorbing hole 6 and the sound-absorbing groove 5, the propagation path of the sound waves in the cavity structure 14 can be extended, and the oblique design allows the high-frequency sound waves to contact the sound-absorbing layer 13 more fully, thereby improving the high-frequency absorption effect.

[0049] In one embodiment, the sound-absorbing hole 6 includes a low-frequency hole structure 61, which is a tapered hole with a diameter that gradually increases from the outside to the inside.

[0050] In one embodiment, the aperture spacing between each of the low-frequency aperture structures 61 is 8-10 mm.

[0051] In actual processing, the outer diameter of the low-frequency hole structure 61 can be 3-3.5mm, and the inner diameter can be 4.5-5mm. The low-frequency hole structure 61 can achieve a smooth gradient by designing the outer diameter from 3-3.5mm to the inner diameter from 4.5-5mm, combined with a hole depth of 10-15mm, so as to avoid sound wave reflection disorder caused by abrupt size changes. Specifically, low-frequency sound waves enter through the low-frequency hole structure 61 and form reflection superposition in the tapered gradually expanding structure, enhancing the resonance absorption effect. If the low-frequency sound waves enter from the obliquely set sound-absorbing hole 6, they pass through the corresponding sound-absorbing groove 5, form directional resonance with the groove wall, and then enter the sound-absorbing cavity through the sound-absorbing layer 13. If the low-frequency sound waves do not enter from the obliquely set sound-absorbing hole 6, they directly enter the sound-absorbing cavity through the sound-absorbing layer 13. Regardless of the way the low-frequency sound waves enter, after entering the sound-absorbing layer 13, they simultaneously form resonance with the sound-absorbing layer 13 and the cavity wall in the sound-absorbing cavity, and cancel the low-frequency vibration frequency through energy conversion.

[0052] In this embodiment, by adopting a tapered low-frequency aperture structure 61 with the aperture gradually increasing from the outside to the inside, the incident sound wave can be reflected and superimposed within the aperture by utilizing the gradually expanding structure of the tapered aperture, thereby enhancing the resonance absorption effect of low-frequency sound waves and effectively solving the problem of insufficient low-frequency noise absorption capacity of traditional straight aperture structures. By controlling the aperture spacing to 8-10mm, the weakening of the sound wave interference effect due to excessively small aperture spacing can be avoided, thus enabling the low-frequency aperture structure 61 to form a stable sound absorption frequency band in a wider low-frequency range.

[0053] In one embodiment, the sound-absorbing hole 6 includes a high-frequency hole structure 62, which is a cylindrical straight hole.

[0054] In one embodiment, the aperture spacing between each of the high-frequency aperture structures 62 is 15-20 mm.

[0055] In actual processing, the aperture of the high-frequency hole structure 62 can be 1-2mm. Its small aperture can adapt to the characteristics of high-frequency sound waves, which is conducive to the high-frequency sound waves entering the high-frequency hole structure 62 and rubbing against the hole wall. The high-frequency sound waves are attenuated through frictional dissipation. Combined with the hole depth design of 5-8mm, the problem of high-frequency sound waves that have not been fully dissipated being reflected due to insufficient hole depth can be avoided. Specifically, high-frequency sound waves enter through the high-frequency hole structure 62, rub against the hole wall in the cylindrical straight hole, and achieve initial energy attenuation through frictional dissipation. Then, they pass through the sound-absorbing layer 13, and are continuously reflected, diffused, and rubbed in the porous structure of the sound-absorbing layer 13, further dissipating energy. Finally, they enter the sound-absorbing cavity, and are reflected multiple times in the cavity, further enhancing the effect of frictional energy dissipation.

[0056] In this embodiment, by setting a high-frequency hole structure 62 with cylindrical straight holes, the structural characteristics of the cylindrical straight holes can be utilized to allow high-frequency sound waves to be directly and smoothly transmitted into the sound-absorbing layer 13. By setting the hole spacing between each high-frequency hole structure 62 to 15-20mm, the mutual interference of sound waves caused by the hole spacing being too small can be avoided, ensuring that the high-frequency hole structure 62 can stably perform its absorption function of high-frequency sound waves.

[0057] In one embodiment, the interior of the structural frame 11 and the covering structure 2 is coated with a functional material (not shown).

[0058] It should be noted that the functional materials (not shown) may include two categories: one is a 2-3 mm low-elasticity soft material coated on the inner wall of the hollow structure 1, which has fireproof, shockproof, and sound insulation properties and is harmless to the human body. Specifically, flame-retardant butyl rubber, neoprene rubber, or similar materials can be selected; the other is a 1-3 mm carbon-containing medium-foamed microporous material coated on the inner wall of the hollow structure 1, which has flame-retardant, heat-insulating, and sterilization functions. Specifically, carbon-containing flame-retardant polyurethane foam can be selected; the interior of the covering structure 2 may be coated with at least two functional materials (not shown) with matching material properties, including the above materials, to form a synergistic effect and improve the overall comprehensive performance.

[0059] In this embodiment, by applying the aforementioned functional material (not shown) inside the structural frame 11 and the covering structure 2, on the one hand, the fireproof, shockproof, and sound insulation properties of the low-elasticity soft material can be utilized to enhance the overall stability and sound insulation foundation of the structure. In conjunction with the sound-absorbing holes 6, sound-absorbing cavities, and other structures, the noise blocking and absorption effect can be further enhanced. On the other hand, the flame-retardant, heat-insulating, and sterilization functions of the carbon-containing foamed microporous material can be utilized to improve the fire safety level of the structural components and reduce heat transfer to achieve a heat insulation effect.

[0060] In one embodiment, the outer surface of the covering structure 2 is covered with a flexible material layer (not shown).

[0061] It should be noted that the flexible material layer (not shown) can be any flexible material such as wood, fabric, stone, or metal produced from a plastic resin film, in order to simulate the visual texture and surface texture of the corresponding material.

[0062] In this embodiment, by covering the outer surface of the covering structure 2 with the aforementioned flexible material layer (not shown), on the one hand, the wall structure can obtain a variety of decorative appearances while possessing functions such as sound absorption, heat insulation, and fire resistance, so as to meet the aesthetic needs of different scenarios and achieve the integration of functionality and decoration; on the other hand, the flexible material layer (not shown) made of plastic resin film is thin and has good adhesion, which can tightly cover the surface of the structure, protecting the covering structure 2 from external wear without adding extra structural thickness, and is also cheaper than natural decorative materials, thus improving the decorative effect while further balancing comprehensive performance and production costs.

[0063] Working principle: This invention achieves noise reduction through the combination of sound-absorbing holes 6, sound-absorbing layer 13, and sound-absorbing cavity: sound-absorbing holes 6 guide sound waves in, where low-frequency sound waves resonate with sound-absorbing layer 13 and cavity wall in the sound-absorbing cavity after entering through sound-absorbing holes 6, and cancel the low-frequency vibration frequency through energy conversion; high-frequency sound waves are absorbed by the porous structure of sound-absorbing layer 13 when passing through sound-absorbing holes 6, and attenuation is achieved through frictional dissipation.

[0064] The structural frame 11 of the hollow structure 1 forms a cavity structure 14. One side of the cavity structure 14 is covered by the covering structure 2 and the other side is covered by the sound-absorbing layer 13. The hollow structure 1 is connected to the external keel by the mounting component 12 with a mortise and tenon structure. The mounting component 12, the sound-absorbing layer 13 and the external keel together form a sound-absorbing cavity. When the mortise and tenon structure is fully installed, the mounting frame at the edge of the mounting component 12 fits into the keel to stabilize the sound-absorbing cavity.

[0065] Functional materials (not shown) are applied inside the structural frame 11 and the covering structure 2, including a low-elasticity soft material and a carbon-containing medium-foamed microporous material applied to the inner wall of the hollow structure 1. At least two functional materials (not shown) with matching properties are applied inside the covering structure 2 to form a synergistic effect. The low-elasticity soft material enhances the overall stability and sound insulation of the structure, and works with the sound-absorbing holes 6, sound-absorbing cavities and other structures to further enhance the noise blocking and absorption effect. The carbon-containing medium-foamed microporous material improves the fire safety level and thermal insulation effect of the structure. The combination of the above structures and functional materials (not shown) makes the process of canceling low-frequency vibration and absorbing high-frequency sound waves stable.
