Description

Technical Field

[0001] This utility model relates to the field of wall panel technology, and in particular to a prefabricated wall panel structure. Background Technology

[0002] Wall panels are an important prefabricated component in prefabricated buildings. Produced industrially in factories, they are characterized by fast construction speed, high quality, wide applicability, and strong plasticity, allowing architects to fully express their facade design concepts. Therefore, prefabricated wall panel structures have been widely used throughout the country. Furthermore, as a new type of decorative wall material, wall panels offer advantages such as convenient and quick installation, saving time and effort, good interchangeability, multiple disassembly and reuse, no deformation, and long lifespan. Wall panels also have a strong absorption effect on ultraviolet rays and radiation, and excellent sound insulation, thus effectively protecting human health.

[0003] Existing technology, such as the patent document with application number CN202322281964.5, discloses an anti-deformation unit for manufacturing door panels and wall panels. This utility model provides an anti-deformation unit for manufacturing door panels and wall panels that uses an enclosed interlocking installation method to further enhance anti-deformation capabilities while also providing operational protection. An anti-deformation unit for manufacturing door panels and wall panels includes a solid wood veneer board, solid wood veneer edge banding strips, rounded corners, and aluminum alloy strips. Solid wood veneer edge banding strips are connected to both sides of the solid wood veneer board, and rounded corners are connected to the top of each solid wood veneer edge banding strip. An aluminum alloy strip is connected to the inner side of each solid wood veneer edge banding strip, and the bottom of each aluminum alloy strip is connected to the top of the solid wood veneer board. This utility model uses solid wood veneer boards and solid wood veneer edge banding strips to enclose and cover the honeycomb aluminum, achieving staggered interlocking assembly. Increasing the hardness of the solid wood veneer edge banding strips makes the edge banding effect smoother, thus providing stronger support and enhancing anti-deformation capabilities during use.

[0004] Although the above-mentioned technical solution has a certain resistance to deformation, the fireproof board on the visible surface is fixedly connected to the internal structure. When subjected to impact, the fireproof board on the visible surface is easily damaged, which requires the replacement of the entire wall panel, thus wasting resources. Utility Model Content

[0026] refer to Figure 1 As shown, the assembled wall panel structure according to an embodiment of the present utility model includes a base plate 100. A sound insulation layer, a reinforcing buffer layer, and a decorative panel 400 are sequentially connected on the base plate 100 from the inside to the outside. The sound insulation layer includes a sound-absorbing plate, a plurality of first grooves 220 evenly spaced in the sound-absorbing plate, and a sound-absorbing plate 230 connected to the side of the sound-absorbing plate facing the reinforcing buffer layer. The sound-absorbing plate 230 covers the first grooves 220, and a sound-absorbing cavity is formed between the sound-absorbing plate 230 and the first grooves 220. A first sound-absorbing cotton 240 is connected in the sound-absorbing cavity. A plurality of first sound-absorbing holes 231 are opened on the sound-absorbing plate 230. The reinforcing buffer layer and the decorative panel 400 are detachably assembled and connected.

[0027] In practical use, the trim panel and the reinforced buffer layer are set to provide impact resistance and sound insulation. At the same time, the trim panel and the reinforced buffer layer are detachably connected, so only the trim panel needs to be replaced when it is damaged, thereby increasing the overall service life, reducing the number of replacements and maintenance, and thus reducing the cost of use.

[0028] In some specific embodiments of this utility model, it may also have the following additional technical features: the outer periphery of the substrate 100 and the decorative panel 400 are both connected with edge sealing 500, and the edge sealing 500 is connected to the substrate 100, the sound insulation layer, the reinforcing buffer layer and the decorative panel 400 respectively by sealant 510.

[0029] refer to Figure 2 As shown, in some specific embodiments of this utility model, it may also have the following additional technical features: the sound-absorbing plate includes a hard layer 211 and a soft layer 212 covering the outer periphery of the hard layer 211, a first groove 220 is formed in the hard layer 211 and the opening of the first groove 220 sequentially penetrates the hard layer 211 and the soft layer 212 and faces the reinforcing buffer layer, and the outer surface of the soft layer 212 is connected to the sound-absorbing plate 230 and the substrate 100 respectively.

[0030] In some specific embodiments of this utility model, it may also have the following additional technical features: the rigid layer 211 is made of thermoplastic plastic material, and the soft layer 212 is made of viscoelastic damping material. Specifically, the rigid layer 211 can be made of materials such as PC, ABS, and nylon, and the soft layer 212 can be made of materials such as leather and slush molding material;

[0031] Of course, it should be noted that the above materials are all commonly used materials in the prior art, so they will not be described in detail.

[0032] Through the above design, the vibrations generated by sound can be transmitted through the hard layer 211, while the soft layer 212 absorbs these vibrations and the resonances generated by the vibrations. At the same time, different materials bring different sound absorption and sound insulation effects, which can achieve better wide-band sound absorption and sound insulation effects.

[0033] In some specific embodiments of this utility model, it may also have the following additional technical features: a plurality of dot-shaped protrusions (not shown in the figure) are evenly connected on the outer surface of the soft layer 212. The dot-shaped protrusions leave gaps for air circulation between the sound insulation layer and the substrate 100 and the reinforcing buffer layer, thereby absorbing a portion of the noise vibration through airflow resonance.

[0034] In some specific embodiments of this utility model, it may also have the following additional technical features: a corrugated plate is connected to the inner wall of the first groove 220, the corrugated plate includes a first corrugated plate 251, a second sound-absorbing cotton 252 and a second corrugated plate 253 connected sequentially from the inside to the outside, and the second corrugated plate 253 is connected to the inner wall of the first groove 220.

[0035] The corrugated structure in corrugated board can absorb some of the sound wave energy, reducing sound reflection and echo. When sound waves encounter corrugated board, they will undergo multiple reflections and refractions inside the cardboard, thereby dissipating some energy and weakening the sound. In conjunction with the soundproofing layer, it can reduce the transmission of noise to the outside, thus forming effective sound insulation.

[0036] In some specific embodiments of this utility model, it may also have the following additional technical features: a plurality of second sound-absorbing holes 254 are evenly spaced on both the first corrugated plate 251 and the second corrugated plate 253. Through the second sound-absorbing holes 254, a portion of the sound can directly enter the space between the first corrugated plate 251 and the second corrugated plate 253 and come into contact with the second sound-absorbing cotton 252. This allows the sound to resonate with the sound that first passes through the first corrugated plate 251 and then enters the space between the first corrugated plate 251 and the second corrugated plate 253, thus weakening each other. Combined with the second sound-absorbing cotton 252, the sound can be further reduced.

[0037] In some specific embodiments of this utility model, it may also have the following additional technical features: the first sound-absorbing cotton 240 is located on the central axis of the first groove 220, and there is a gap between the first corrugated plate 251 and the first sound-absorbing cotton 240. The gap is used for air circulation, so that some noise vibration can be absorbed through airflow resonance.

[0038] In some specific embodiments of this utility model, it may also have the following additional technical features: a plurality of through holes 255 are evenly spaced through the corrugated plate. Through the through holes 255, some sound passes directly through the corrugated plate, contacts and reflects the inner wall of the first groove 220, and then re-enters the corrugated plate, where it collides and resonates with other sounds within the corrugated plate, thereby achieving a wider frequency absorption effect.

[0039] In some specific embodiments of this utility model, it may also have the following additional technical features: the reinforced buffer layer includes a first hard plate 310, a rubber layer 320 and a second hard plate 330 connected in sequence, the first hard plate 310 is connected to the sound-absorbing plate 230 and the second hard plate 330 is connected to the decorative plate 400.

[0040] In some specific embodiments of this utility model, it may also have the following additional technical features: a plurality of second grooves 321 are evenly spaced on the rubber layer 320, a rubber pad 322 is connected in the second groove 321, the rubber pad 322 is connected to the second hard plate 330, and the second hard plate 330 is detachably assembled and connected to the decorative panel 400. The side of the second hard plate 330 facing the decorative panel 400 has an assembly protrusion 331, and the decorative panel 400 has a corresponding assembly groove 410, and the assembly protrusion 331 is detachably connected to the assembly groove 410. Preferably, the decorative panel 400 has a notch (not shown in the figure) in the circumferential direction for easy insertion, so that the decorative panel 400 can be quickly removed from the second hard plate 330 and replaced by a tool.

[0041] Specifically, the hardness of the rubber pad 322 is greater than that of the rubber layer 320. Through this design, the impact force encountered by the trim panel 400 is first transmitted to the second hard plate 330, and then dispersed to the rubber layer 320 and the rubber pad 322. Because the hardness of the rubber pad 322 is greater than that of the rubber layer 320, the rubber pad 322 provides support and cushioning. Simultaneously, the rubber layer 320 dissipates the impact force through deformation and returns to its original state after the impact force disappears, thus effectively improving overall durability.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
