Description

Technical Field

[0001] This application relates to the field of building materials technology, and more specifically, to a lightweight building wall panel. Background Technology

[0002] With the increasing demands for energy conservation, environmental protection, and construction efficiency in the construction industry, lightweight building wall panels have been widely used in modern buildings due to their advantages such as light weight and convenient construction. However, existing lightweight wall panels are prone to sound bridging at the joints, which causes sound to propagate through the gaps and reduces sound insulation performance, especially in low-frequency noise environments (such as traffic noise).

[0003] While some wall panels improve sound insulation by adding sealing strips or adjusting the connection structure, these measures still have limitations in practical applications. For example, the sealing and stability of the joints may weaken due to long-term use or external environmental influences, thus reducing overall sound insulation performance. Therefore, optimizing the joint structure to block sound transmission paths has become one of the important directions for improving the overall performance of lightweight wall panels.

[0004] The above problems indicate that there is still room for improvement in controlling the sound bridging effect at the joints of existing lightweight building wall panels, especially in terms of sound insulation performance in low-frequency noise environments, in order to meet the needs of modern buildings for high efficiency, energy saving and comfortable environment. Summary of the Invention

[0005] The purpose of this invention is to provide a lightweight building wall panel that aims to improve the overall sound insulation performance of the wall panel by optimizing the joint structure design and internal sound-absorbing structure, thereby blocking the sound propagation path, while maintaining the advantages of lightweight and easy construction.

[0006] To achieve the above objectives, the present invention provides a lightweight building wall panel, comprising: a main board, wherein a through cavity is provided in the middle of the main board, and the cavity is filled with sound-absorbing material;

[0007] The cavity is equipped with multiple partitions, which divide the cavity into several independent small chambers. The sound-absorbing material filled in each small chamber is glass fiber or mineral wool.

[0008] A connecting component disposed on the edge of the main body plate includes a positioning strip, a sealing block, and an elastic gasket. The positioning strip is fixed to the edge of the main body plate, the sealing block is embedded in the positioning strip, and the elastic gasket is disposed between the sealing block and the positioning strip.

[0009] The sealing block is made of a flexible polymer and has an internal cavity structure filled with low-frequency sound-absorbing particles. These particles are a mixture of polyurethane foam particles and graphite microparticles; the weight ratio of the polyurethane foam particles to the graphite microparticles is 10:1 to 5:1, and the particle diameter ranges from 0.5 mm to 1 mm. The cavity structure is formed using injection molding. This cavity design allows the sealing block to undergo elastic deformation upon mating, ensuring a tight fit between adjacent wall panels and forming a continuous sound barrier.

[0010] One of the sealing blocks has a flange structure on its mating surface, and the mating surface of the adjacent sealing block has a groove structure that mates with the flange structure, so as to form a fitting sealing connection when mating.

[0011] Furthermore, both the front and back of the main body panel are covered with a sound insulation film, which is bonded to the main body panel through a hot-melt process to form an integrated structure. A decorative layer is provided on the sound insulation film.

[0012] Furthermore, the positioning strip has a U-shaped cross-section and contains multiple evenly spaced limiting protrusions. These protrusions contact the outer surface of the sealing block to restrict its movement. The U-shaped structure of the positioning strip is bolted to the edge of the main body plate, with the bolts positioned at the two wing ends of the positioning strip to ensure a stable connection between the positioning strip and the main body plate. The limiting protrusions are made of hard plastic with anti-slip textures to enhance friction with the sealing block and prevent displacement of the sealing block during long-term use.

[0013] Optionally, the thickness of the elastic gasket in its natural state is greater than the installation space between the positioning strip and the sealing block, and it is in a pre-compressed state after assembly, thereby applying continuous elastic pressure to the sealing block through its own elastic restoring force.

[0014] Optionally, the elastic gasket has a thickness of 1 mm to 3 mm, and its two sides are respectively attached and fixed to the inner walls of the sealing block and the positioning strip. The elastic gasket is made of silicone, and its surface is coated with a waterproof coating with a coating thickness of 0.1 mm to 0.2 mm. The elastic gasket is fixed between the sealing block and the positioning strip by adhesive, and the adhesive cures for 24 hours to ensure that the elastic gasket has stable support performance after installation.

[0015] Optionally, the thickness of the partition plate is 2 mm to 5 mm, and its material is rigid polyurethane foam.

[0016] Optionally, the surface of the partition plate is coated with a waterproof coating. The coating thickness is 0.1 mm to 0.3 mm. The partition plate is fixed to the inner wall of the cavity by a snap-fit ​​structure with a snap-fit ​​spacing of 10 cm to 15 cm to ensure the stability of the partition plate within the main body plate.

[0017] Optionally, the two sides of the main body plate are provided with symmetrical slots. The width of the slots matches the thickness of the positioning strip. The U-shaped structure of the positioning strip is inserted into the slots and fixed to the main body plate by bolts passing through its two side wings, thereby achieving a stable connection.

[0018] Optionally, the inner wall of the slot is provided with anti-slip texture. The depth of the slot is 5 mm to 8 mm, and the anti-slip texture on its inner wall is formed by laser engraving, with a spacing of 1 mm to 2 mm. The slot design allows the positioning strip to be quickly positioned and firmly fixed during installation, preventing loosening due to external vibration.

[0019] Optionally, both the front and back of the main body panel are covered with a sound-insulating film. The sound-insulating film is bonded to the main body panel via a hot-melt process to form an integrated structure. A decorative layer is provided on the sound-insulating film, and the decorative layer is bonded to the sound-insulating film via a pressing process. The sound-insulating film has a thickness of 0.5 mm to 1 mm and is made of ethylene-vinyl acetate copolymer. The surface of the sound-insulating film has a microporous structure with micropores having a diameter of 0.1 mm to 0.3 mm. The decorative layer is made of polyvinyl chloride and has a thickness of 0.8 mm to 1.2 mm. The surface of the decorative layer has a textured pattern formed by a heat transfer process.

[0020] Optionally, the surface of the decorative layer is further coated with a protective coating. The thickness of the protective coating is 0.1 mm to 0.3 mm. The protective coating is made of polyurethane with a surface hardness of 2H to 3H. The protective coating is applied to the surface of the decorative layer by a spraying process, and the sprayed coating is then cured by ultraviolet light for 10 to 15 minutes.

[0021] The embodiments of this invention have the following technical effects: First, by setting a through cavity inside the main body panel and filling the cavity with sound-absorbing material, and by using a partition plate to divide the cavity into multiple independent small chambers, this invention effectively improves the sound absorption performance of the wall panel, especially significantly enhancing its ability to absorb low-frequency noise. Second, by setting a connecting component at the edge of the main body panel, the sealing block and elastic gasket in the connecting component work together. Simultaneously, the cavity structure filled with low-frequency sound-absorbing particles inside the sealing block, combined with the pressure applied by the elastic gasket, achieves both physical sealing and targeted low-frequency sound absorption at the connection seam. This forms a continuous sound barrier at the connection seam, blocking the sound propagation path and significantly reducing the impact of the sound bridge effect. Third, by optimizing the design of the connecting component, this invention enables the wall panel to be quickly positioned and firmly fixed during installation, simplifying the construction process, improving construction efficiency, and maintaining the advantage of lightweight construction.

[0033] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0034] The lightweight building wall panel and its application method of the present invention achieve their technical effects through specific structural design and installation steps. The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Figures 1 to 8 The overall structure and some details of the invention are shown respectively. For example... Figures 1 to 3 As shown, in this embodiment, the lightweight building wall panel includes a main body panel 1 and connecting components disposed at the edge of the main body panel 1. The main body panel 1 is the core component of the lightweight building wall panel, and its overall shape is a rectangular flat plate with a thickness between 10 mm and 20 mm. The material used is a lightweight polymer composite material to ensure that the wall panel is lightweight yet possesses sufficient strength. A through cavity 2 is provided in the center of the main body panel 1, and the cavity 2 is filled with sound-absorbing material 21. Figures 6 to 7 As shown, the connecting assembly includes a positioning strip 31, a sealing block 32, and an elastic gasket 33. The positioning strip 31 is fixed to the edge of the main body plate 1. The sealing block 32 is embedded in the positioning strip 31 and mates with the sealing block 32 of the adjacent wall panel. One sealing block 32 has a flange structure on its mating surface, and the mating surface of the adjacent sealing block 32 has a groove structure that mates with the flange structure, forming a fitted seal connection during mating. The elastic gasket 33 is located between the sealing block 32 and the positioning strip 31 and applies constant pressure. The thickness of the elastic gasket 33 in its natural state is greater than its installation space between the positioning strip 31 and the sealing block 32. After assembly, it is in a pre-compressed state, thereby applying continuous elastic pressure to the sealing block 32 through its own elastic restoring force.

[0035] like Figure 3 As shown, the positioning strip 31 is fixed to the edge of the main body plate 1. Its cross-section is U-shaped, and its two wing ends are connected to the main body plate 1 by bolts. The bolts are installed at the two wing ends of the positioning strip 31 to ensure the stability of the connection between the positioning strip 31 and the main body plate 1. In addition, the positioning strip 31 has a plurality of equally spaced limiting protrusions 34 inside. The limiting protrusions 34 are made of hard plastic and have anti-slip textures on their surface to enhance the friction between them and the sealing block 32.

[0036] The sealing block 32 is embedded in the positioning strip 31 and mates with the sealing block 32 of the adjacent wall panel. The sealing block 32 is made of flexible polymer and has an internal cavity structure, such as... Figure 8 As shown, the cavity structure is formed by injection molding, and the cavity is filled with low-frequency sound-absorbing particles 4. The low-frequency sound-absorbing particles 4 are composed of polyurethane foam particles and graphite microparticles, with a weight ratio of polyurethane foam particles to graphite microparticles of 10:1 to 5:1, and the particle diameter ranges from 0.5 mm to 1 mm, which can effectively absorb low-frequency noise.

[0037] like Figure 7 As shown, an elastic gasket 33 is disposed between the sealing block 32 and the positioning strip 31. Its thickness is 1 mm to 3 mm, and it is made of silicone with a waterproof coating on its surface, the coating thickness being 0.1 mm to 0.2 mm. The elastic gasket 33 is fixed between the sealing block 32 and the positioning strip 31 by an adhesive. The adhesive cures for 24 hours to ensure stable support performance of the elastic gasket 33 after installation.

[0038] The cavity 2 has multiple partition plates 5 inside, which divide the cavity 2 into several independent small chambers, each of which is filled with sound-absorbing material 21. Figure 2 and 5 As shown, the partition plate 5 has a thickness of 2 mm to 5 mm, is made of rigid polyurethane foam, and has a waterproof coating with a thickness of 0.1 mm to 0.3 mm. The partition plate 5 can be fixed to the inner wall of the cavity 2 via a snap-fit ​​structure with a snap-fit ​​spacing of 10 cm to 15 cm to ensure the stability of the partition plate 5 within the cavity 2. The sound-absorbing material 21 is made of glass fiber or mineral wool, with a density of 20 kg / m³. 3 Up to 50kg / m 3 It can effectively absorb mid-to-high frequency noise and reduce sound wave reflection.

[0039] The main body plate 1 has symmetrical slots 22 on both sides, such as... Figure 4As shown, the width of the slot 22 matches the thickness of the positioning strip 31, and the depth is 5 mm to 8 mm. The inner wall is provided with anti-slip texture. The anti-slip texture is formed by laser engraving, and the spacing of the texture is 1 mm to 2 mm, ensuring that the positioning strip 31 can be quickly positioned and firmly fixed during installation.

[0040] In addition, both the front and back of the main body panel 1 are covered with a layer of sound insulation film 6, such as Figure 3 As shown, the sound insulation film 6 is integrated with the main body panel 1 through a hot-melt process to form an integral structure. It has a thickness of 0.5 mm to 1 mm and is made of ethylene-vinyl acetate copolymer. The surface has a microporous structure with micropores having a diameter of 0.1 mm to 0.3 mm. A decorative layer 7 is provided on the sound insulation film 6. The decorative layer 7 is bonded to the sound insulation film 6 through a pressing process. It is made of polyvinyl chloride and has a thickness of 0.8 mm to 1.2 mm. The surface has a textured pattern formed by a heat transfer process. A protective coating 8 is also coated on the surface of the decorative layer 7. The protective coating 8 has a thickness of 0.1 mm to 0.3 mm, is made of polyurethane, and has a surface hardness of 2H to 3H. It is applied to the surface of the decorative layer 7 through a spraying process, and the sprayed coating is then cured with ultraviolet light for 10 to 15 minutes.

[0041] The method of using the lightweight building wall panel of the present invention includes the following steps. First, multiple wall panels are installed one by one on the wall surface, ensuring that the connecting components of each wall panel are aligned with the connecting components of adjacent wall panels. One sealing block has a flange structure on its mating surface, and the mating surface of the adjacent sealing block has a groove structure that mates with the flange structure, forming a fitted seal connection during mating. During installation, it should be ensured that the pre-fixed elastic gasket 33 is uniformly compressed, thereby applying uniform elastic pressure to the sealing block 32, ensuring a uniform pressure distribution between the sealing block 32 and the positioning strip 31, and avoiding a decrease in sealing performance due to uneven pressure. Subsequently, the sealing performance between adjacent wall panels is tested, and the gap value at the mating point of the sealing blocks 32 is recorded, ensuring that the gap value is less than 0.2 mm to meet sound insulation requirements. The lightweight building wall panel of the present invention is an integral prefabricated component, and its protective coating 8 is applied and cured on the surface of the decorative layer 7 before the product leaves the factory. Its on-site installation method mainly includes installing multiple wall panels one by one on the wall surface, ensuring that the connecting components are tightly aligned. After installation, no additional surface coating treatment is required.

[0042] This invention achieves the design goals of lightweight building wall panels through the aforementioned specific structure and installation steps. The design of the cavity 2 and partition plate 5 inside the main panel 1 allows the sound-absorbing material 21 to be evenly distributed within the cavity 2, thereby effectively absorbing mid-to-high frequency noise. The cavity structure of the sealing block 32 and the low-frequency sound-absorbing particles 4 can absorb low-frequency noise at the joints, while the elastic gasket 33 further enhances the sealing performance and blocks the sound propagation path. The combination of the sound insulation film 6 and the decorative layer 7 not only improves the overall sound insulation performance of the wall panel but also enhances its aesthetics and durability. The application of the protective coating 8 further improves the anti-aging performance and service life of the wall panel. By optimizing the design of the connecting components, the wall panel can be quickly positioned and firmly fixed during installation, simplifying the construction process, improving construction efficiency, and maintaining the advantages of lightweight construction.

[0043] To enable those skilled in the art to fully understand and implement this invention, the specific implementation principle of this invention will be further explained below in conjunction with a specific application scenario.

[0044] In actual construction, the edge groove 22 of the main panel 1 is first aligned with the positioning strip 31 pre-installed on the wall surface. Multiple wall panels are assembled using connecting components. During installation, it is crucial to ensure that the anti-slip texture of the positioning strip 31 fits tightly against the inner wall of the groove 22 when it is embedded, thus preventing the wall panel from easily loosening after installation. Simultaneously, the limiting protrusion 34 inside the positioning strip 31 contacts the outer surface of the sealing block 32. The anti-slip texture design of the limiting protrusion 34 enhances friction, preventing the sealing block 32 from shifting due to long-term use or external vibration.

[0045] The contact surface between the sealing block 32 and the adjacent wall panel forms a flange and groove mating structure (or mortise and tenon structure). When the two wall panels are mated, the flange on one side is embedded into the groove on the other side, and a tight fit is achieved through the elastic deformation of the sealing block, thus forming a continuous sound barrier. The low-frequency sound-absorbing particles 4 in the cavity structure are composed of a mixture of polyurethane foam particles and graphite microparticles, with a diameter ranging from 0.5 mm to 1 mm. These particles can resonate during sound wave propagation, converting sound energy into heat energy, thereby effectively absorbing low-frequency noise. In addition, the elastic gasket 33 between the sealing block 32 and the positioning strip 31 is adjusted to ensure uniform pressure distribution between the sealing block 32 and the positioning strip 31, avoiding a decrease in sealing performance due to uneven pressure.

[0046] Meanwhile, the internal cavity 2 and partition plates 5 of the main body panel 1 also play a crucial role. The cavity 2 is divided into several independent small chambers by multiple partition plates 5, each filled with sound-absorbing material 21 such as fiberglass or mineral wool. After sound waves enter the cavity 2, they are reflected multiple times between the partition plates 5 and ultimately absorbed by the sound-absorbing material 21. The rigid polyurethane foam material and waterproof coating of the partition plates 5 not only improve their stability but also enhance their moisture resistance, thereby extending the service life of the wall panel.

[0047] After installation, the sealing performance between adjacent wall panels needs to be tested. The gap at the joint of the sealing blocks 32 is measured to ensure it is less than 0.2 mm to meet sound insulation requirements. The wall panels of this invention are prefabricated components; all coatings (including the protective coating 8) are prepared before leaving the factory, requiring only splicing and installation on site. The polyurethane material of the protective coating 8 has high hardness, effectively resisting external wear and aging, thereby improving the overall durability of the wall panels.

[0048] The sound insulation membrane 6 further enhances the sound insulation effect of the wall panel. The sound insulation membrane 6 is bonded to the main panel 1 via a hot-melt process, and its microporous surface structure effectively blocks the propagation of sound waves. Simultaneously, the decorative layer 7 is bonded to the sound insulation membrane 6 via a pressing process; its textured pattern not only enhances aesthetics but also conceals any minor imperfections that may exist on the surface of the wall panel. The PVC material of the decorative layer 7 possesses good flexibility and weather resistance, enabling it to adapt to various environmental conditions.

[0049] In summary, this invention achieves high-efficiency sound insulation and convenient construction by optimizing the internal structure and connecting component design of the wall panel. The cavity 2, partition plate 5, and sound-absorbing material 21 inside the main panel 1 work together to effectively absorb mid-to-high frequency noise; the cavity structure of the sealing block 32 and the low-frequency sound-absorbing particles 4 are specifically optimized for low-frequency noise; the elastic gasket 33 further enhances the sealing performance and blocks the sound propagation path. The combination of the sound insulation film 6 and the decorative layer 7 not only improves the overall sound insulation performance but also enhances aesthetics and durability. The application of the protective coating 8 further improves the anti-aging performance and service life of the wall panel. Through the combination of the above specific steps and principles, this invention can meet the needs of modern buildings for high efficiency, energy saving, and a comfortable environment.
