Description

Technical Field

[0001] This utility model relates to the field of soundproof wall panels, and more specifically, to an assembled soundproof wall panel. Background Technology

[0002] With the acceleration of urbanization and the increase in building density, noise pollution has become increasingly serious, significantly impacting people's quality of life and work. Traditional sound insulation materials, such as concrete and bricks, while having good sound insulation effects, are heavy and complex to construct, making it difficult to meet the demands of modern buildings for lightweight and rapid installation. Therefore, the demand for sound insulation materials is growing rapidly in the fields of construction, transportation, and industry.

[0003] A search revealed that Chinese Patent Publication No. CN222227110U discloses "an assembled soundproof wall panel, comprising: a base, with a second fixing frame and a first fixing frame fixedly installed on the left and right sides of the top of the base, and a soundproof panel movably connected to the top of the base. This invention, by setting up a vertical rod, a moving plate, an mounting plate, an inclined rod, and a clamping plate, allows the mounting plate to be pushed upwards, causing the moving plate to move vertically upwards under the limiting action of the vertical groove and the vertical rod, and also causing the inclined rod to move. At this time, due to the limiting action of the rectangular groove, the clamping plate moves horizontally backwards. When the circular groove moves to the position of the second threaded rod, the second threaded rod is rotated, allowing it to fully enter the interior of the circular groove, thus achieving the fixing effect of the moving plate, facilitating the disassembly and assembly of the soundproof panel, improving the disassembly and assembly efficiency of the device, and reducing the labor intensity of the operators." However, the following defects still exist:

[0004] The current device involves a series of complex components, including vertical rods, moving plates, mounting plates, diagonal rods, and clamping plates, to install the sound insulation panels. The operation is cumbersome and difficult for a single person to operate. Furthermore, the device lacks joint sealing measures, and over time, the gaps between the wall panels are prone to widening due to factors such as building settlement and temperature changes, leading to a decline in sound insulation performance and a short service life. Therefore, an assembled sound insulation wall panel is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the problems of existing devices that require a series of complex components such as vertical rods, moving plates, mounting plates, diagonal rods, and clamping plates to install sound insulation panels. These components involve cumbersome operation steps, making it difficult for a single person to operate. Furthermore, the device lacks joint sealing measures, which can lead to a decrease in sound insulation performance and a short service life over time due to factors such as building settlement and temperature changes.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] like Figure 1 and Figure 3 As shown, this embodiment proposes an assembled soundproof wall panel, including a wall panel base 1, an assembly mechanism 2 for quick assembly is provided on the side wall of the wall panel base 1, and a sound insulation mechanism 3 for improving the sound insulation performance of the wall panel base 1 is provided inside the wall panel base 1.

[0032] like Figure 6 and Figure 7 As shown, the assembly mechanism 2 includes a tenon 201 fixedly connected to the side wall of the wall panel base 1. A groove 202 is provided on the side wall of the wall panel base 1, with the groove 202 opposite to the tenon 201. The groove 202 and the tenon 201 cooperate to achieve horizontal splicing using a mortise and tenon structure. The tenon 201 is inserted into the groove 202 to achieve rapid assembly of the wall panel base 1. Two elastic sealing strips 203 are provided on the inner wall of the groove 202. The compression deformation of the elastic sealing strips 203 generates friction, improving the sealing performance of the wall panel base 1 connection. In use, splicing is achieved by inserting the tenon 201 on one side into the groove 202 on the other side, forming a mechanical interlock. The elastic sealing strip 203 deforms under pressure on the inner wall of the groove 202, filling gaps and blocking the airborne sound transmission path.

[0033] like Figure 3 and Figure 5As shown, the sound insulation mechanism 3 includes a keel support 301 disposed inside the wall panel substrate 1. The distance between the two keel supports 301 is 100mm. The interior of the keel support 301 is filled with sound-absorbing particles 302. The keel support 301 provides a frame to support the wall panel substrate 1. The distance between the two keel supports 301 forms an air layer to reduce solid sound transmission. The sound-absorbing particles 302 filled in the keel support 301 consume sound energy and absorb sound waves through pore friction. A damping layer 303 is disposed on the side wall of the two keel supports 301. The damping layer 303 suppresses keel vibration through its properties. A sound-absorbing layer 304 is disposed on the side wall of the two damping layers 303. The open structure forms an acoustic porous material. Through viscous resistance, the sound wave quantity is reduced. The side wall of the two sound-absorbing layers 304 is tightly attached to the inner wall of the wall panel substrate 1. In use, the keel support 301 provides a frame and supports the wall panel base 1. At the same time, the two keel supports 301 maintain a distance to form an air layer, which absorbs low-frequency sound waves through resonance and reduces solid-borne sound transmission. The sound-absorbing particles 302 filled inside the keel support 301 consume sound energy through pore friction and absorb mid-frequency sound waves. The damping layer 303 attenuates the structural resonance of the keel support 301 by constraining the damping structure. The sound-absorbing layer 304 repeatedly refracts and rubs sound waves through internal interconnected pores, which efficiently absorbs high-frequency sound waves.

[0034] like Figure 8 As shown, a sealing cover plate 4 is provided on the top of the wall panel base 1, and the sealing cover plate 4 is bolted to the splice surface of the wall panel base 1. After the wall panel base 1 is assembled, the sealing cover plate 4 is fixed to the splice surface of the wall panel by bolts, covering the connection between the tenon 201 and the groove 202, further enhancing the sealing and structural stability.

[0035] like Figure 1 As shown, polyester fiber sound-absorbing panels 5 are provided on the sidewall of the wall panel substrate 1. Several polyester fiber sound-absorbing panels 5 are evenly distributed along the height direction of the wall panel substrate 1. In use, the polyester fiber sound-absorbing panels 5 can absorb mid-to-high frequency sound waves through the micropores between the fibers, thereby improving indoor reverberation.

[0036] like Figure 1 As shown, the material of the wall panel substrate 1 is calcium silicate board. In use, the calcium silicate board serves as a load-bearing structure, while also providing sound insulation through its high-density material.

[0037] like Figure 5 As shown, the damping layer 303 is made of butyl rubber damping felt. Butyl rubber damping felt is a viscoelastic material made of butyl rubber as the base material and with the addition of fillers, plasticizers and other components. When used, it can achieve wide-frequency vibration reduction and noise reduction by viscoelastic energy dissipation.

[0038] like Figure 5As shown, the sound-absorbing layer 304 is made of polyurethane foam. Polyurethane foam is composed of a large number of interconnected micropores. When in use, when sound waves are incident, air molecules rub against the foam skeleton intensely, and the sound energy is converted into heat energy through viscous resistance, absorbing mid-to-high frequency sound waves.

[0039] Specifically, when using this assembled soundproof wall panel: the tenon 201 on one side is inserted into the groove 202 on the other side to achieve splicing, forming a mechanical interlock. The elastic sealing strip 203 is deformed under pressure on the inner wall of the groove 202, filling the gaps and blocking the airborne sound transmission path (e.g., Figure 6 and Figure 7 As shown), the keel support 301 provides a frame and supports the wall panel substrate 1. A gap is maintained between the two keel supports 301 to form an air layer, which absorbs low-frequency sound waves through resonance, reducing solid-borne sound transmission. The sound-absorbing particles 302 filling the keel support 301 dissipate sound energy through pore friction, absorbing mid-frequency sound waves. The damping layer 303 attenuates the structural resonance of the keel support 301 through a constrained damping structure. The sound-absorbing layer 304, through its internal interconnected pores, allows sound waves to be repeatedly refracted and rubbed, efficiently absorbing high-frequency sound waves (such as...). Figure 3 and Figure 5 As shown), the polyester fiber sound-absorbing panel 5 can absorb mid-to-high frequency sound waves through the micropores between the fibers, while improving indoor reverberation (e.g., Figure 1 As shown), after the wall panel base 1 is assembled, the sealing cover 4 is fixed to the surface of the wall panel joint with bolts, covering the connection between the tenon 201 and the groove 202, further enhancing the sealing and structural stability (as shown). Figure 8 (As shown).

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
