Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building materials and building structure, specifically is a kind of composite wall component with double function of heat insulation and sound insulation. BACKGROUND

[0002] In the modern construction field, wall component as the important component of building, its performance directly influences the comfort, energy saving and environmental protection of building. With the continuous improvement of people's demand to living environment, wall component not only needs to have basic load-bearing function, but also needs to meet multiple demands such as heat insulation and sound insulation. Especially in hot or cold regions, good heat insulation performance can effectively reduce energy consumption, and excellent sound insulation performance can significantly improve the comfort of indoor environment. However, the existing wall component still has many deficiencies in realizing the double function of heat insulation and sound insulation.

[0003] Traditional wall component usually adopts single material or simple composite structure design, and it is difficult to simultaneously consider heat insulation and sound insulation performance. For example, some wall components improve heat insulation effect by increasing thickness, but this way often leads to increase of material consumption, rise of construction cost, and limited improvement of sound insulation performance. Although some wall components improve sound insulation effect by adding sound-absorbing materials, these materials may affect the overall heat insulation performance of wall, and even reduce its structural strength. In addition, part of composite wall component in prior art also has problems such as complex installation and poor durability in actual application, which further limits its popularization and use.

[0004] Therefore, developing a composite wall component that can efficiently insulate heat and well insulate sound becomes a technical problem to be solved in current construction field. This new type of wall component needs to realize the optimized balance of heat insulation and sound insulation performance while ensuring structural strength and construction convenience, so as to meet the higher requirements of modern buildings on energy saving, environmental protection and comfort.

In addition, composite wall component in prior art is usually complex in structure, inconvenient to install, and prone to aging problem of heat insulation layer or sound insulation layer in long-term use, leading to performance decline, difficult to meet the requirements of modern buildings on efficient energy saving and environmental protection.

[0007] The purpose of this utility model embodiment is to provide a composite wall component with both heat insulation and sound insulation functions, aiming to solve the problems mentioned in the background art.

[0008] This utility model embodiment is implemented as follows: a composite wall component with dual functions of heat insulation and sound insulation includes a base plate, a heat insulation layer disposed on one side of the base plate, and further includes:

[0009] A sound insulation layer is fixed to the other side of the substrate. The sound insulation layer is made of porous sound-absorbing material. A reflective film is fixedly connected to the side of the heat insulation layer away from the substrate. Multiple micro-protrusion structures are evenly distributed on the reflective film.

[0014] Preferably, the micro-protrusion structure on the reflective film is hemispherical, with a height of 0.2mm to 0.5mm and a spacing of 1mm to 2mm between adjacent protrusions.

[0024] This utility model provides a composite wall component with both heat insulation and sound insulation functions, the specific implementation of which is as follows (in conjunction with the appendix). Figure 1 To be continued Figure 3 A detailed description is provided. The composite wall component in this embodiment includes a substrate 1, a heat insulation layer 2, a sound insulation layer 3, a reflective film 4, a decorative panel 5, vents 6, a one-way vent valve 7, reinforcing ribs 8, a vacuum insulation board 9, aerogel particles 10, connecting components, and related auxiliary structures. These components, through reasonable design and material selection, achieve excellent performance in terms of heat insulation, sound insulation, ease of installation, airtightness, and durability.

[0025] like Figure 1 As shown, the overall layout of the composite wall component uses a base plate 1 as its core structure. A heat insulation layer 2 is installed on one side of the base plate 1, and a sound insulation layer 3 is fixed to the other side. The base plate 1 provides the basic support for the entire wall component, and multiple reinforcing ribs 8 are embedded within it. These reinforcing ribs 8 are spaced apart along the length of the base plate 1, and have an I-shaped cross-section. This design not only improves the overall strength of the base plate 1 but also significantly enhances its bending resistance, allowing the wall component to withstand greater external forces without easily deforming during installation and use. Furthermore, both the upper and lower surfaces of the base plate 1 are provided with anti-slip textures. These textures are staggered diamond patterns with a depth ranging from 0.3mm to 0.8mm. The anti-slip texture design effectively enhances the grip and stability of the base plate 1 during installation, especially when the wall component needs to be moved or fixed during construction, preventing slippage.

[0026] The heat insulation layer 2 is located on one side of the substrate 1, and contains multiple layers of vacuum heat insulation plates 9. Low thermal conductivity aerogel particles 10 are filled between the vacuum heat insulation plates 9. The vacuum environment inside the vacuum heat insulation plates 9 significantly reduces heat conduction efficiency, while the aerogel particles 10 further fill any possible micro-gaps, thereby minimizing heat transfer. The heat insulation layer 2 is fixedly connected to the substrate 1 using a highly adhesive epoxy resin adhesive. This adhesive not only ensures a strong bond between the two but also maintains stable performance during long-term use, avoiding peeling problems caused by aging. A reflective film 4 is fixedly connected to the side of the heat insulation layer 2 away from the substrate 1. Multiple micro-protrusion structures 16 are evenly distributed on the reflective film 4, such as... Figure 2As shown. These micro-protrusion structures 16 are hemispherical, with a height ranging from 0.2 mm to 0.5 mm, and the spacing between adjacent protrusions is 1 mm to 2 mm. The reflective film 4 is fixedly connected to the heat insulation layer 2 by a hot-pressing process to ensure its structural stability. The outer surface of the reflective film 4 is coated with a weather-resistant coating, which can effectively resist the erosion of external environmental factors such as ultraviolet rays and rainwater, thereby extending the service life of the reflective film 4. The reflective film 4 and its micro-protrusion structures 16 not only improve heat reflection efficiency but also enhance the mechanical strength of the heat insulation layer 2, making it less prone to damage during long-term use.

[0027] The sound insulation layer 3 is located on the other side of the substrate 1 and is made of porous sound-absorbing material. The porous sound-absorbing material has excellent sound wave absorption properties, capable of converting incident sound waves into heat energy and dissipating them, thereby effectively reducing noise propagation. A decorative panel 5 is fixedly connected to the side of the sound insulation layer 3 away from the substrate 1. The decorative panel 5 has multiple micropore arrays 17, such as... Figure 2 As shown. The micropore array 17 has an aperture range of 0.5mm to 1mm. This design further enhances the sound absorption and diffusion effect while maintaining the aesthetics of the decorative panel 5. The surface of the decorative panel 5 is treated with an anti-fouling coating to effectively prevent the adhesion of dust and stains, thereby extending its service life and maintaining a clean appearance.

[0028] Multiple through-holes 6 are provided on the substrate 1, and a one-way vent valve 7 is provided in each of the vent holes 6, such as... Figure 2 As shown, the one-way vent valve 7 is made of flexible silicone material and has an opening pressure range of 5 Pa to 10 Pa. The one-way vent valve 7 effectively prevents external moisture from entering the wall while allowing internal moisture to escape, thus keeping the wall dry. This design not only helps prevent dampness inside the wall but also avoids mold growth caused by moisture accumulation, thereby improving the durability and environmental performance of the wall components.

[0029] The connecting components are located on both sides of the base plate 1 and are used to achieve quick connection and sealing between adjacent wall components. The connecting components include multiple spaced-apart slots 11 and blocks 12. The slots 11 are fixed to one side edge of the base plate 1, and the blocks 12 are fixed to the other side edge of the base plate 1, as shown below. Figure 3As shown, the slot 11 and the block 12 are connected by an elastic element 13. The elastic element 13 is made of rubber with damping properties, which provides a certain buffering effect during the connection process, thereby reducing the risk of damage caused by external impact. Sealing strips 14 are provided on the mating surfaces of the slot 11 and the block 12. The sealing strips 14 are used to enhance the airtightness between adjacent wall components and prevent air or moisture from seeping in from the joint. In addition, positioning pins 15 are also provided on the mating surfaces of the slot 11 and the block 12. The ends of the positioning pins 15 have a chamfered structure to facilitate insertion and positioning. This design allows adjacent wall components to be quickly aligned during installation, thereby improving construction efficiency.

[0030] In practical applications, the composite wall component of this invention can be widely used in residential buildings, commercial buildings, and industrial plants. For example, in residential buildings, this wall component can be used as an exterior or interior wall. Its heat insulation layer 2 can effectively block the intrusion of external heat, thereby reducing indoor air conditioning energy consumption; the sound insulation layer 3 can significantly reduce external noise interference, providing residents with a quieter and more comfortable environment. In commercial buildings, this wall component can be used in places with high sound insulation requirements, such as conference rooms or recording studios. Its porous sound-absorbing material and microporous array 17 design can effectively absorb and diffuse sound, thereby achieving ideal sound insulation effects. In industrial plants, this wall component can be used in large spaces such as workshops or warehouses. Its reinforcing ribs 8 and connecting components design can ensure the stability and safety of the wall during long-term use.

[0031] In summary, this invention achieves the dual function of a wall component by setting a heat insulation layer 2 and a sound insulation layer 3 on both sides of the substrate 1. The vacuum insulation board 9 and aerogel particles 10 in the heat insulation layer 2 significantly reduce heat conduction efficiency, while the reflective film 4 and its micro-protrusion structure 16 further improve heat reflection efficiency. The sound insulation layer 3 uses porous sound-absorbing material and, combined with the micro-pore array 17 design on the decorative panel 5, effectively enhances sound absorption and diffusion. The reinforcing ribs 8 embedded inside the substrate 1 and the design of the connecting components make the wall component easier to install, while ensuring the stability and airtightness of the overall structure. In addition, the one-way vent valve 7 in the vent 6 effectively keeps the wall dry, thereby extending its service life. Through reasonable structural design and material selection, this invention, while satisfying the dual functions of heat insulation and sound insulation, also features convenient installation, stable performance, and long service life, providing an efficient solution for modern buildings.
