Description

Technical Field

[0001] This utility model relates to the field of architectural decoration technology, specifically to a noise-reducing hyperbolic aluminum panel. Background Technology

[0002] In the current construction and decoration field, hyperbolic aluminum panels are widely used in large public buildings, transportation hubs, and other places with high requirements for acoustic environment due to their beautiful shape and modern feel. However, traditional aluminum panel products have obvious limitations in noise reduction: First, their noise reduction structure is often designed for specific frequency bands, making it difficult to effectively absorb and block noise in a wide range of frequencies such as mid-high and low frequencies, resulting in a narrow overall noise reduction range and unsatisfactory effect; Second, existing noise-reducing aluminum panels mostly adopt an integral bonding or one-time encapsulation structure, and the internal acoustic materials cannot be replaced after aging or performance degradation. Maintenance requires the entire panel to be disassembled and replaced, which is not only cumbersome and costly, but also wastes materials.

[0003] To address the aforementioned issues, this application proposes a noise-reducing hyperbolic aluminum panel. Utility Model Content

[0004] The purpose of this utility model is to provide a noise-reducing hyperbolic aluminum panel to solve the problems mentioned in the background art, such as limited noise reduction frequency band coverage, poor effect, and the need for overall replacement and high cost for maintenance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a noise-reducing hyperbolic aluminum single panel, comprising a decorative panel and a back panel, wherein a porous sound-absorbing layer, a honeycomb support layer and a damping sound insulation layer are sequentially provided between the decorative panel and the back panel from the decorative panel to the back panel.

[0006] Preferably, the porous sound-absorbing layer is made of glass wool or polyester fiber cotton, the honeycomb support layer is made of aluminum honeycomb or paper honeycomb, and the damping sound insulation layer is made of rubber asphalt or composite material damping sheet.

[0007] Preferably, the front end and both sides of the decorative panel are integrally formed with a frame flange extending towards the back side, and the end of the frame flange is connected to a pressing edge extending horizontally towards the center of the panel; the back panel is a hollow structure with the center protruding upwards, and its front end and the bottom of both sides are connected to a fixing piece extending horizontally outwards, and the fixing piece is located below the pressing edge.

[0008] Preferably, the front edge of the back panel is provided with a vertically downward mounting edge, and the front edge of the decorative panel is provided with a connecting edge, the distance between the connecting edge and the front edge of the decorative panel being equal to the thickness of the mounting edge.

[0009] Preferably, the connecting edge and the mounting edge are fitted together, and both the connecting edge and the mounting edge are provided with mounting holes and are fixedly connected by bolts.

[0010] Preferably, the lower hollow area of ​​the back panel is provided with at least one clamping strip, which is used to support and clamp the damping sound insulation layer.

[0011] Preferably, a sealing strip is provided on the side of the pressing edge facing the middle of the decorative panel, and the sealing strip is a strip structure made of rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a stable space for sound insulation components by enclosing a sealed cavity with a decorative panel and back panel. The porous sound-absorbing layer inside the cavity absorbs mid-to-high frequency noise through its pores, while the honeycomb core layer maintains the strength of the hyperbolic structure and disperses noise energy. The damping sound insulation layer blocks the transmission of low-frequency noise through its damping properties. The sealing strip at the pressing edge fills the edge gap to prevent sound leakage, comprehensively covering noise of different frequencies. This solves the problems of narrow noise reduction range and poor effect of traditional hyperbolic aluminum single panels, and meets the sound insulation needs of multiple scenarios.

[0013] This utility model uses bolts to fix the decorative panel and the back panel together with the connecting edge and the mounting edge. When disassembling, simply unscrew the bolts and pull the back panel to one side to separate the back panel from the decorative panel. There is no need to remove them separately. After separation, the aged porous sound-absorbing layer, honeycomb support layer and damping sound insulation layer can be directly replaced without replacing the whole panel. This greatly reduces maintenance costs, saves manpower and time, and extends the service life of the equipment. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figures 1-5 This utility model provides a technical solution: a noise-reducing hyperbolic aluminum panel, comprising a decorative panel 1 and a back panel 2. Between the decorative panel 1 and the back panel 2, a porous sound-absorbing layer 3, a honeycomb support layer 4, and a damping sound-insulating layer 5 are sequentially arranged from the decorative panel 1 towards the back panel 2. The decorative panel 1 and the back panel 2 together form a cavity to accommodate the internal functional layers. The porous sound-absorbing layer 3, honeycomb support layer 4, and damping sound-insulating layer 5, arranged sequentially from the decorative panel 1 towards the back panel 2, absorb mid-to-high frequency noise, the honeycomb support layer 4 supports the structure and disperses noise energy, and the damping sound-insulating layer 5 blocks low-frequency noise, achieving comprehensive noise reduction across a wide frequency range. Simultaneously, the assembly structure of the decorative panel 1 and the back panel 2 provides space for subsequent disassembly and replacement of the internal sound-insulating layer. It eliminates the need to replace the entire aluminum panel; only the panel and back panel 2 need to be separated to replace the aged or damaged sound-insulating layer, thus balancing noise reduction effectiveness and maintenance convenience.

[0017] The porous sound-absorbing layer 3 is composed of glass wool or polyester fiber cotton, the honeycomb support layer 4 is composed of aluminum honeycomb or paper honeycomb, and the damping sound insulation layer 5 is composed of rubber asphalt or composite material damping sheets. The porous sound-absorbing layer 3 uses glass wool or polyester fiber cotton, utilizing its internal porous structure to convert mid-to-high frequency noise into heat energy through friction within the pores, effectively absorbing mid-to-high frequency noise. The honeycomb support layer 4 uses aluminum honeycomb or paper honeycomb, providing the structural strength required for the hyperboloid shape with its honeycomb-shaped hollow structure, while simultaneously dispersing energy through multiple reflections and scattering of noise through the honeycomb pores. The damping sound insulation layer 5 uses rubber asphalt or composite material damping sheets, utilizing the damping internal friction characteristics to convert low-frequency noise vibration energy into heat energy, combined with the sound insulation sheet to block low-frequency transmission. All selected materials are suitable for disassembly and replacement; when replacing the sound insulation layer, materials of the same specifications can be directly replaced, ensuring stable noise reduction performance without adjusting the overall structure.

[0018] The decorative panel 1 has an integrally formed frame flange 6 extending towards the back side at the front end and both sides. The end of the frame flange 6 is connected to a pressing edge 7 extending horizontally towards the center of the panel. The back panel 2 has a hollow structure with the center protruding upwards, and its front end and the bottom of both sides are connected to a fixing piece 8 extending horizontally outwards. The fixing piece 8 is located below the pressing edge 7. The edge 6 of the decorative panel 1 extends towards the back and horizontally through the pressing edge 7, providing an enclosing installation edge for the back panel 2. The back panel 2 adopts a hollow structure with an upward convex center, which reduces weight and reserves space for the internal sound insulation layer. The fixing plates 8 at the front end and the bottom of both sides are located below the pressing edge 7, and the upper end of the back panel 2 is at the same height as the pressing edge 7, ensuring that the decorative panel 1 and the back panel 2 are parallel after assembly, avoiding gaps caused by height differences that could lead to noise leakage. At the same time, the mating connection between the fixing plate 8 and the pressing edge 7 facilitates disassembly, allowing the panel and back panel 2 to be separated without damaging the overall structure, thereby quickly replacing the internal porous sound-absorbing layer 3, honeycomb support layer 4, or damping sound insulation layer 5, improving maintenance convenience.

[0019] The front edge of the back panel 2 has a vertically downward mounting edge 9, and the front edge of the decorative panel 1 has a connecting edge 10. The distance between the connecting edge 10 and the front edge of the decorative panel 1 is equal to the thickness of the mounting edge 9. The mounting edge 9 on the front edge of the back panel 2 is set vertically downward, and the distance between the connecting edge 10 and the front edge of the decorative panel 1 is equal to the thickness of the mounting edge 9. This size design allows the connecting edge 10 and the mounting edge 9 to fit precisely during assembly, providing a positioning reference for subsequent fixed connection, forming a preliminary sealing structure at the fitting point to reduce noise transmission from the front gap, and facilitating quick alignment and installation of the front end of the double-curved aluminum panel. After fitting, the front surfaces of the decorative panel 1 and the back panel 2 are at the same level, further avoiding gaps. At the same time, the precise positioning structure also facilitates reassembly when disassembling and replacing the internal sound insulation layer, ensuring that good noise reduction and sealing effects are maintained after disassembly and reassembly.

[0020] The connecting edge 10 and the mounting edge 9 are fitted together, and both the connecting edge 10 and the mounting edge 9 have mounting holes and are fixedly connected by bolts. After the connecting edge 10 and the mounting edge 9 are fitted together, they are fixedly connected by bolts in the mounting holes of both, which can not only firmly connect the front end of the decorative panel 1 and the back panel 2 to ensure the overall structural strength, but also compress the fitting gap by tightening the bolts to enhance the front end sealing and reduce noise transmission. At the same time, the bolt connection method is easy to disassemble. Only by unscrewing the bolts can the connecting edge 10 and the mounting edge 9 be separated, and then the decorative panel 1 and the back panel 2 can be separated, so as to realize the quick replacement of the internal sound insulation layer without replacing the entire aluminum single panel, thus reducing maintenance costs.

[0021] At least one clamping strip 11 is provided in the lower hollow area of ​​the back panel 2. The clamping strip 11 is used to support and clamp the damping sound insulation layer 5. The clamping strip 11 provided in the lower hollow area of ​​the back panel 2 supports and clamps the damping sound insulation layer 5 from below, ensuring that the damping sound insulation layer 5 is in close contact with the honeycomb support layer 4 and the back panel 2, and avoiding a decrease in the low-frequency noise blocking effect due to loosening. At the same time, the support structure of the clamping strip 11 does not hinder the disassembly operation. After the decorative panel 1 and the back panel 2 are separated, the clamping strip 11 can be directly removed and the damping sound insulation layer 5 or other internal sound insulation layers can be replaced, ensuring that the replacement process is convenient. After reassembly, the position of the sound insulation layer can still be stabilized by the clamping strip 11 to maintain the noise reduction effect.

[0022] A sealing strip 12 is provided on the side of the pressing edge 7 facing the middle of the decorative panel 1. The sealing strip 12 is a strip-shaped structure made of rubber. After assembly, the sealing strip 12 is compressed between the pressing edge 7 and the back panel 2 or the internal sound insulation layer. It fills the gap with elastic deformation to form a sealing barrier to reduce noise transmission from the edge gaps and enhance the overall noise reduction effect. At the same time, the elasticity of the sealing strip 12 does not hinder the separation of the decorative panel 1 and the back panel 2. When disassembling, the sealing strip 12 can naturally detach as the pressing edge 7 separates from the back panel 2, without affecting the replacement of the internal sound insulation layer, ensuring the repeatability of the noise reduction sealing structure during disassembly and assembly.

[0023] Working principle: In actual use, this noise-reducing hyperbolic aluminum panel first achieves sound insulation through a multi-layer structure: the decorative panel 1 and the back panel 2 enclose a sealed cavity, and a porous sound-absorbing layer 3 (glass wool or polyester fiber cotton) is arranged sequentially from the decorative panel 1 to the back panel 2 inside the cavity, which absorbs mid-to-high frequency noise through its internal pores; the honeycomb support layer 4 (aluminum honeycomb or paper honeycomb) not only supports the hyperbolic structure to ensure strength, but also disperses noise energy through the honeycomb pores; the damping sound insulation layer 5 (rubber asphalt or composite material damping sheet) uses damping characteristics to block the transmission of low-frequency noise; at the same time, the sealing strip 12 on the side of the panel with the pressing edge 7 close to the middle of the panel fills the gap after assembly to form a sealing barrier, reducing noise leakage from the edge gaps and achieving wide-frequency noise reduction. If the internal sound insulation components are damaged and need to be replaced, simply unscrew the fixing bolts on the connecting edge 10 and the mounting edge 9. Since the connecting edge 10 is connected to the decorative panel 1 and the mounting edge 9 is connected to the back panel 2, the decorative panel 1 and the back panel 2 can be directly separated after the bolts are removed. At this time, the fixing piece 8 on the back panel 2 moves synchronously with the back panel 2, and the clamping strip 11 also remains connected to the back panel 2. The aged porous sound-absorbing layer 3, honeycomb support layer 4 and damping sound insulation layer 5 can be directly removed from the cavity gap between the decorative panel 1 and the back panel 2. When installing the new sound insulation layer, place the porous sound-absorbing layer 3 first, then the honeycomb support layer 4, and finally the damping sound insulation layer 5 into the cavity of the back panel 2. Then, align the fixing piece 8 of the back panel 2 with the lower edge 7 of the decorative panel 1 and engage it, so that the connecting edge 10 and the mounting edge 9 are precisely fitted (ensuring that the front surfaces of the two are at the same level). The damping sound insulation layer 5, the honeycomb support layer 4, and the porous sound-absorbing layer 3 are supported and pressed by the clamping strip 11 under the back panel 2. Finally, tighten the bolts to fix the connecting edge 10 and the mounting edge 9. The sealing strip 12 is compressed and sealed under the action of the clamping edge 7, completing the sound insulation layer replacement without replacing the entire aluminum panel.

[0024] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
