Description

Technical Field

[0001] This application relates to the field of panel technology, specifically to a heat-insulating and noise-reducing composite panel for the exterior walls of high-rise buildings. Background Technology

[0002] Composite panels are an innovative type of building material designed specifically for the exterior walls of high-rise buildings. By employing advanced materials and processes, composite panels maintain the strength and durability of traditional building materials.

[0003] Regarding the aforementioned technologies, existing composite panels generally lack good thermal insulation and noise reduction performance. This drawback has multiple disadvantages. In cases of poor thermal insulation, outdoor heat can easily be conducted into the room during hot summer months, leading to excessively high indoor temperatures and increased energy consumption for air conditioning or other cooling equipment. This not only increases operating costs but also contradicts the principles of energy conservation and environmental protection. Conversely, in winter, indoor heat is easily lost, making it difficult to maintain a comfortable indoor temperature and requiring even more energy to keep warm. As for noise reduction, the lack of effective noise reduction allows external noise, such as traffic or construction noise, to easily enter the room, interfering with people's normal lives and rest, reducing living comfort, and potentially even having a negative impact on people's physical and mental health. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a heat-insulating and noise-reducing composite panel for the exterior walls of high-rise buildings, which has the advantages of good heat insulation and noise reduction.

[0006] To achieve the above objectives, this application provides the following technical solution: A frame is included, the frame having an internal reflective heat insulation layer, a vacuum heat insulation board, and a fastening plate. The reflective heat insulation layer is made of color-coated steel sheet, the surface of which is coated with aluminum foil. Aerogel is disposed on one side of the color-coated steel sheet, and the other side of the aerogel is disposed on the side of the vacuum heat insulation board. Foamed ceramic is disposed on one side of the vacuum heat insulation board, and the other side of the foamed ceramic is disposed on the side of the fastening plate. A gradient density sound-absorbing layer, made of glass wool, is disposed on one side of the gradient density sound-absorbing layer, made of polymer damping coating. The other side of the damping sound-absorbing layer is fixedly connected to the side of the fastening plate.

[0007] The above scheme utilizes a reflective heat insulation layer to efficiently reflect solar radiation heat using the aluminum foil coating on the surface of the color steel plate, reducing heat absorption. Simultaneously, aerogel, as a super heat insulation material, effectively prevents heat conduction through the frame. The synergistic effect of these two elements enhances the thermal insulation performance of the composite panel. A vacuum insulation panel is installed to block heat convection in a vacuum environment, further reducing heat conduction efficiency in conjunction with the porous structure of foamed ceramics, forming multiple thermal barriers. A gradient density sound-absorbing layer is installed inside the fastening plate, utilizing the sound wave absorption characteristics of different density regions of glass wool to attenuate mid-to-high frequency noise in a gradient manner. Combined with the polymer damping coating of the damping sound insulation layer, sound energy is converted into heat energy and effectively blocks the propagation of low-frequency noise, thus constructing a complete noise reduction system.

[0008] Furthermore, the frame is provided with several threaded holes at both the top and bottom;

[0009] The above solution, by setting threaded holes, allows for a secure connection between the composite panel and the exterior wall of a high-rise building via bolts, ensuring the stability and reliability of the composite panel installation. It also facilitates the disassembly, replacement, and maintenance of the composite panel later.

[0010] Furthermore, the fastening plate has a wallpaper decorative layer on its side;

[0011] The above solution, by setting a wallpaper decorative layer, can enhance the aesthetics of the composite board, making it easier for it to blend into the overall decoration style of high-rise buildings. It can also protect the sides of the fastener to a certain extent, preventing them from being corroded or damaged due to long-term exposure to the external environment.

[0012] Furthermore, a humidity sensor is provided at the bottom of the fastening plate, and a display is fixedly installed on the side of the wallpaper decorative layer;

[0013] The above solution, by setting up a humidity sensor, can monitor the humidity of the environment in which the composite panel is located in real time and transmit the data to a display. The display then shows the humidity information in an intuitive digital or graphical form. When the ambient humidity exceeds the preset safe range, an alarm can be issued in time to remind relevant personnel to take measures to prevent the performance of the composite panel from deteriorating due to excessive humidity, thus ensuring the stability and reliability of the composite panel during its use on the exterior walls of high-rise buildings.

[0014] Furthermore, the frame is internally provided with a self-cleaning high-strength finish layer, the material of which is a ceramic plate;

[0015] The above solution, by setting a self-cleaning high-strength finish layer and using ceramic plate material, can achieve a self-cleaning effect due to the smooth surface of the ceramic plate and its characteristics of not easily absorbing dust and dirt. This reduces the frequency and difficulty of manual cleaning. At the same time, the high strength of the ceramic plate can withstand a certain amount of external impact and is not easily damaged, which can effectively protect the internal structure of the frame.

[0016] Furthermore, a waterproof and breathable layer is provided on the side of the self-cleaning high-strength decorative layer. The waterproof and breathable layer is made of a breathable board, and a polymer film is provided on the surface of the breathable board.

[0017] The above solution, by setting a waterproof and breathable layer, using a breathable board material, and placing a polymer film on its surface, allows moisture inside the composite board to be smoothly discharged, taking advantage of the good breathability of the breathable board. This prevents moisture accumulation from damaging the internal structure. At the same time, the polymer film has excellent waterproof performance, which can effectively prevent external moisture from penetrating into the interior of the composite board, ensuring the normal use of the composite board in humid environments and improving the durability and stability of the composite board.

[0018] Furthermore, a drainage hole is provided on the side of the ceramic plate, and a filter screen is provided inside the drainage hole;

[0019] The above solution, by setting drainage holes and installing filters inside them, ensures that water droplets do not linger on the surface of the composite board for a long time, thus avoiding potential corrosion of the composite board by water droplets. The filter also prevents external insects from entering the interior of the composite board.

[0020] Furthermore, the glass wool structure in the gradient density sound-absorbing layer has a density that gradually increases from the outside to the inside;

[0021] The above scheme, by setting a gradient density sound-absorbing layer and gradually increasing the density of the glass wool structure from the outside to the inside, allows sound waves to first encounter the relatively low-density glass wool when entering the composite board. The sound waves can easily enter and undergo initial attenuation in this layer. As the sound waves propagate inward, the density of the glass wool gradually increases, and the obstruction effect on the sound waves also gradually strengthens, thereby achieving multi-stage attenuation of sound waves.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This is a heat-insulating and noise-reducing composite panel for the exterior walls of high-rise buildings. By setting a reflective heat insulation layer, it can efficiently reflect solar radiation heat using the aluminum foil coating on the surface of the color steel plate, reducing heat absorption. At the same time, aerogel, as a super heat insulation material, can effectively prevent heat from being conducted through the frame. The two work together to improve the heat insulation performance of the composite panel. By setting a vacuum heat insulation panel, the vacuum environment is used to block heat convection, and the porous structure of foamed ceramic further reduces heat conduction efficiency, forming multiple heat insulation barriers. By setting a gradient density sound-absorbing layer inside the fastening plate, the sound wave absorption characteristics of different density areas of glass wool can be used to attenuate mid-to-high frequency noise in a gradient manner. Combined with the polymer damping coating of the damping sound insulation layer, the sound energy is converted into heat energy and consumed, effectively blocking the propagation of low-frequency noise, thus constructing a complete noise reduction system.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 2 and Figure 4 This embodiment describes a heat-insulating and noise-reducing composite panel for the exterior walls of high-rise buildings, comprising a frame 1. The frame 1 contains a reflective heat-insulating layer 10, a vacuum heat-insulating panel 12, and a fastening plate 16. The reflective heat-insulating layer 10 is made of color-coated steel sheet 11, with an aluminum foil coating 20 on its surface. Aerogel 14 is disposed on one side of the color-coated steel sheet 11, and the other side of the aerogel 14 is disposed on the side of the vacuum heat-insulating panel 12. Foamed ceramic 13 is disposed on one side of the vacuum heat-insulating panel 12, and the other side of the foamed ceramic 13 is disposed on the side of the fastening plate 16. A gradient density sound-absorbing layer 5, made of glass wool, is disposed on the side of the gradient density sound-absorbing layer 5. A damping sound-insulating layer 15, made of polymer damping coating, is disposed on the other side of the fastening plate 16. On the side of the panel 16, a reflective heat insulation layer 10 is provided, which can efficiently reflect solar radiation heat by utilizing the aluminum foil film 20 on the surface of the color steel plate 11, reducing heat absorption. At the same time, the aerogel 14, as a super heat insulation material, can effectively prevent heat from being conducted through the interior of the frame 1. The two work together to improve the heat insulation performance of the composite panel. By setting a vacuum heat insulation board 12, the vacuum environment is used to block heat convection. Combined with the porous structure of the foamed ceramic 13, the heat conduction efficiency is further reduced, forming multiple heat insulation barriers. By setting a gradient density sound absorption layer 5 inside the fastening plate 16, the sound wave absorption characteristics of different density areas of glass wool can be used to attenuate mid-to-high frequency noise in a gradient manner. Combined with the polymer damping coating of the damping sound insulation layer 15, the sound energy is converted into heat energy and consumed, effectively blocking the propagation of low-frequency noise, thereby constructing a complete noise reduction system.

[0034] Please see Figure 1 and Figure 2 The top and bottom of the frame 1 are provided with several threaded holes 2. By setting the threaded holes 2, it is possible to make the composite panel and the exterior wall of the high-rise building securely connected by bolts, ensuring the firmness and reliability of the composite panel installation. It is also convenient to disassemble and replace the composite panel later. The side of the fastening plate 16 is provided with a wallpaper decorative layer 6. By setting the wallpaper decorative layer 6, the aesthetics of the composite panel can be improved, making it easier to integrate into the overall decoration style of the high-rise building. It can also protect the side of the fastening plate 16 to a certain extent, preventing it from being corroded or damaged due to long-term exposure to the external environment.

[0035] Please see Figure 1 , Figure 2 and Figure 5 A humidity sensor 21 is installed at the bottom of the fastening plate 16, and a display 3 is fixedly installed on the side of the wallpaper decorative layer 6. By setting the humidity sensor 21, the humidity of the environment where the composite board is located can be monitored in real time, and the data is transmitted to the display 3. Then the display 3 displays the humidity information in an intuitive digital or graphical form. When the ambient humidity exceeds the preset safe range, an alarm can be issued in time to remind relevant personnel to take measures to prevent the performance of the composite board from deteriorating due to excessive humidity, thus ensuring the stability and reliability of the composite board in the use of high-rise building exterior walls. The interior of the frame 1 is equipped with a self-cleaning high-strength decorative layer 4. The material of the self-cleaning high-strength decorative layer 4 is ceramic plate 7. By setting the self-cleaning high-strength decorative layer 4 and using ceramic plate 7, the ceramic plate 7 has the characteristics of smooth surface and not easy to absorb dust and dirt, which can achieve the self-cleaning effect, reducing the frequency and difficulty of manual cleaning. At the same time, the ceramic plate 7 has high strength and can withstand a certain amount of external impact, making it less prone to damage and effectively protecting the internal structure of the frame 1.

[0036] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6 The self-cleaning high-strength decorative layer 4 has a waterproof and breathable layer 8 on its side. The waterproof and breathable layer 8 is made of a breathable board 9, and a polymer film 19 is provided on the surface of the breathable board 9. By setting the waterproof and breathable layer 8, using the breathable board 9, and providing the polymer film 19 on its surface, the good breathability of the breathable board 9 allows water vapor inside the composite board to be smoothly discharged, preventing water vapor accumulation and damage to the internal structure. At the same time, the polymer film 19 has excellent waterproof performance, which can effectively prevent external moisture from penetrating into the interior of the composite board, ensuring the normal use of the composite board in humid environments and improving the durability and stability of the composite board. Drainage holes 17 are opened on the side of the ceramic plate 7, and filters are provided inside the drainage holes 17. The mesh 18, with its drainage holes 17 and internal filter screen 18, ensures that water droplets do not linger on the surface of the composite board for extended periods, thus preventing potential erosion. The filter screen 18 also prevents external insects from entering the composite board. The glass wool structure in the gradient density sound-absorbing layer 5 exhibits a gradually increasing density from the outside to the inside. This structure ensures that when sound waves enter the composite board, they first encounter the lower-density glass wool, allowing for easy entry and initial attenuation. As the sound waves propagate inward, the density of the glass wool gradually increases, enhancing its resistance to sound waves and achieving multi-stage attenuation.

[0037] This embodiment describes a heat-insulating and noise-reducing composite panel for the exterior walls of high-rise buildings. It should be noted that by setting a reflective heat insulation layer 10, the aluminum foil coating 20 on the surface of the color steel plate 11 can efficiently reflect solar radiation heat, reducing heat absorption. Simultaneously, the aerogel 14, as a super heat-insulating material, can effectively prevent heat conduction through the interior of the frame 1. The synergistic effect of these two elements improves the heat insulation performance of the composite panel. By setting a vacuum heat insulation board 12, the vacuum environment blocks heat convection, and the porous structure of the foamed ceramic 13 further reduces heat conduction efficiency, forming multiple heat insulation barriers. By setting a gradient density sound-absorbing layer 5 inside the fastening plate 16, the sound wave absorption characteristics of different density areas of the glass wool can be utilized to attenuate mid-to-high frequency noise in a gradient manner. Combined with the polymer damping coating of the damping sound insulation layer 15, sound energy is converted into heat energy and consumed, effectively blocking the propagation of low-frequency noise, thus constructing a complete noise reduction system.

[0038] The working principle of the above embodiment is as follows: First, when solar radiation heat acts on the composite panel, the reflective heat insulation layer 10 inside the outermost frame 1 takes effect first. Then, the aluminum foil film 20 coated on the surface of the color steel plate 11 of the reflective heat insulation layer 10 can reflect most of the solar radiation heat directly with its high reflectivity, greatly reducing the absorption of heat by the composite panel. At the same time, the aerogel 14 on the side of the color steel plate 11, as a super heat insulation material, can effectively block the heat from being conducted through the inside of the frame 1, thus initially achieving the heat insulation effect.

[0039] Then, after the reflective heat insulation layer 10 is applied, if a small amount of heat is still transferred into the interior of the composite panel, it will encounter the vacuum heat insulation board 12. The vacuum heat insulation board 12 then uses the internal vacuum environment to fundamentally block the occurrence of heat convection and prevent the heat from spreading further. At the same time, the foamed ceramic 13 on the side of the vacuum heat insulation board 12 has a porous structure that can effectively reduce the heat conduction efficiency. Subsequently, it works with the vacuum heat insulation board 12 to form a second heat insulation barrier, which improves the heat insulation performance of the composite panel.

[0040] Then, when external noise travels to the composite board, the noise first comes into contact with the gradient density sound-absorbing layer 5 inside the fastening plate 16. At this time, the glass wool structure of the gradient density sound-absorbing layer 5 has the characteristic of gradually increasing density from the outside to the inside, which allows the sound wave to first enter the outer glass wool with lower density and undergo initial attenuation. As the sound wave travels inward, it encounters the glass wool with gradually increasing density, and the resistance it encounters is continuously enhanced. The sound wave energy is gradually consumed, achieving gradient multi-level attenuation of mid-to-high frequency noise.

[0041] Subsequently, if low-frequency noise remains after the noise is attenuated by the gradient density sound-absorbing layer 5 and continues to propagate, it will reach the damping sound insulation layer 15. At this time, the polymer damping coating of the damping sound insulation layer 15 has excellent damping characteristics, which can convert the sound energy of the residual low-frequency noise into heat energy and consume it, effectively blocking the low-frequency noise from propagating to the other side of the composite board. Together with the gradient density sound-absorbing layer 5, it forms a complete noise reduction system and achieves efficient noise reduction.

[0042] Subsequently, during the long-term use of the composite board, the waterproof and breathable layer 8 and the drainage holes 17 continuously ensure its stability. Then, the breathable plate 9 of the waterproof and breathable layer 8 allows the water vapor generated inside the composite board due to temperature changes to be discharged smoothly, preventing water vapor from accumulating and damaging the internal structure. The polymer film 19 on the surface of the breathable plate 9 can prevent external moisture from seeping in. At the same time, the drainage holes 17 on the side of the ceramic plate 7 can drain the water accumulated on the surface of the composite board in time to prevent water droplet erosion. Then, the filter screen 18 inside the drainage holes 17 can also block external insects from entering the board, preventing insects from damaging the internal structure.

[0043] Finally, the humidity sensor 21 can monitor the humidity of the environment where the composite board is located in real time and transmit the data to the display 3 on the side of the wallpaper decorative layer 6. The display 3 can then display the humidity information in an intuitive way. When the ambient humidity exceeds the preset safe range, the system will issue an alarm in time to remind the staff to take moisture-proof measures. At the same time, the ceramic plate 7 of the self-cleaning high-strength decorative layer 4 achieves self-cleaning due to its smooth surface characteristics, reducing the accumulation of dust and dirt. At the same time, its high strength characteristics can also protect the internal structure of the frame 1 from damage by external impact, ensuring that the composite board can stably perform its heat insulation and noise reduction functions for a long time.
