Description

Technical Field

[0001] This utility model relates to the field of sound insulation building materials for architectural decoration, and in particular to a snap-fit ​​quick-assembly sound insulation wall panel. Background Technology

[0002] In building interior decoration, soundproof wall panels are widely used in bedrooms, conference rooms, recording studios, and other settings because they effectively block noise and improve the living or office environment. Existing soundproof wall panels mostly use traditional splicing methods, such as adhesive bonding or single bolt fixing. Adhesive bonding suffers from long curing times and low splicing efficiency, and is prone to cracking at the splice joints due to aging over long-term use. Single bolt fixing requires precise positioning of the wall panel, which is cumbersome, and the single-point force can easily lead to loosening at the splice joint, while the splice gaps are prone to sound leakage, affecting the sound insulation effect. Therefore, a snap-fit, quick-assembly soundproof wall panel is proposed. Utility Model Content

[0003] The present invention aims to provide a snap-on quick-assembly soundproof wall panel, which achieves the purpose of quick positioning and splicing, multi-point stabilization and fastening, optimized sound insulation and sealing effect and improved safety of use.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: A snap-fit, quick-assembly soundproof wall panel includes a wall panel. The wall panel body comprises, along its thickness direction, a base layer, a sound insulation layer, and a finishing layer. The sound insulation layer is sandwiched between the base layer and the finishing layer. A first splicing portion and a second splicing portion are respectively provided on opposite sides of the wall panel body. The first splicing portion is a boss structure extending along the length direction of the wall panel body, and at least one strip-shaped snap-fit ​​groove is formed on its end face along its length direction. The second splicing portion is a boss structure extending along the length direction of the wall panel body, and the second splicing portion is adapted to the boss structure of the first splicing portion. The end face of the wall panel has strip-shaped buckles that correspond to and fit the strip-shaped snap-fit ​​grooves one by one along its length direction; the first splicing part and the second splicing part have fixing holes that penetrate along their thickness direction on their boss structures; the wall panel also includes a fixing plate, which has connecting holes that are coaxially aligned with the fixing holes of the first splicing part and the second splicing part; when the strip-shaped buckle of the second splicing part of one wall panel body is inserted into the strip-shaped snap-fit ​​groove of the first splicing part of another wall panel body, the fixing plate covers the fixing holes of the two splicing parts through the connecting holes, and the two wall panel bodies are mechanically fastened by a screwing component passing through the aligned fixing holes and connecting holes.

[0005] Furthermore, at least two sets of fixing holes are provided at intervals along the length direction on the boss structure of the first splicing part and the second splicing part, and each set of fixing holes includes at least one fixing hole located on the first splicing part and the second splicing part respectively.

[0006] Furthermore, the screwing component is a self-tapping screw, bolt, or rivet, the fixing hole is a threaded hole, and the connecting hole is a countersunk hole.

[0007] Furthermore, the sound insulation layer is at least one of rock wool, glass wool, polyurethane foam, or damping sound insulation board.

[0008] Furthermore, the four sides of the wall panel body are provided with rounded chamfers, and the chamfer radius is 1mm-3mm.

[0009] Furthermore, an elastic sealing element is provided between the mating surfaces of the first splicing part and the second splicing part.

[0010] Compared with the prior art, this utility model has the following advantages: The wall panel is quickly positioned using a combination of strip-shaped buckles and grooves, significantly improving splicing efficiency. At least two sets of spaced threaded fixing holes, combined with screw-on fittings, form multi-point fastening, avoiding uneven stress at a single point and enhancing splicing stability. The sound insulation layer provides basic sound insulation, while elastic seals seal splicing gaps to prevent sound leakage. Countersunk holes, combined with seals, prevent dust and moisture intrusion, extending the wall panel's lifespan. Rounded chamfers eliminate sharp edges to prevent scratches during handling and installation, and the screw-on fitting head is embedded in the countersunk hole to prevent protrusion and scratches, improving safety. Different types of screw-on fittings and various sound insulation layer materials are available, adapting to diverse installation scenarios and offering wide applicability.

Detailed implementation method: The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1-4As shown, the core structure of this utility model provides a snap-fit ​​quick-assembly soundproof wall panel 1, including the wall panel 1 body, side splicing structure, and auxiliary fastening structure. The wall panel 1 body has a three-layer composite structure along its thickness direction, consisting of a base layer 11, a sound insulation layer 12, and a finishing layer 13 from the inside out. The sound insulation layer 12 is sandwiched between the base layer 11 and the finishing layer 13. The base layer 11 provides structural support to ensure the wall panel 1 is not easily deformed. The sound insulation layer 12 is key to blocking sound transmission and achieving sound insulation. The finishing layer 13 directly meets the aesthetic requirements of the wall surface without additional decoration. The wall panel 1 body has matching protrusion structures on opposite sides, namely a first splicing part and a second splicing part. The protrusion end face of the first splicing part has at least one strip-shaped snap-fit ​​groove 21 along the length direction of the wall panel 1. The protrusion structure of the second splicing part is completely adapted to the first splicing part, and its end face has strip-shaped snaps 22 corresponding to the strip-shaped snap-fit ​​grooves 21 along the length direction. When the strip-shaped buckle 22 is inserted into the strip-shaped snap-fit ​​groove 21, the initial positioning and splicing of the two wall panels 1 can be quickly achieved, fulfilling the core requirement of rapid splicing. In addition, the first splicing part and the second splicing part are respectively provided with fixing holes 31 that penetrate the thickness direction. The matching independent component fixing plate 4 is provided with connecting holes 41. The connecting holes 41 are coaxially adapted to the fixing holes 31 that are aligned after splicing. There is also a screwing part 5 for passing through the aligned fixing holes 31 and connecting holes 41. After the initial snap-fit, the fixing plate 4 covers and the screwing part 5 is tightened to strengthen the splicing stability through mechanical fastening, avoiding loosening at the splicing point or falling off and deforming during long-term use. The overall structure is first quickly positioned and spliced ​​by the buckle and groove, and then mechanically fastened by the fixing plate 4 and the screwing part 5. This not only improves the splicing efficiency but also ensures the splicing strength. At the same time, the sound insulation layer 12 continues to play a sound insulation role, and the decorative layer 13 ensures the appearance. Finally, a comprehensive effect of rapid splicing, stability and reliability, sound insulation compliance and beautiful appearance is achieved.

[0017] Structurally, the first and second splicing parts have at least two sets of fixing holes 31 spaced apart along the length of the protrusions. Each set of fixing holes 31 is corresponding in composition, meaning each set includes at least one fixing hole 31 located on the protrusion of the first splicing part, and at least one fixing hole 31 located on the protrusion of the second splicing part, which is compatible with the position of the fixing hole 31 in the first splicing part. Functionally, these fixing holes 31 are one of the key structures for achieving a stable splicing of the two wall panels 1. When the second splicing part of one wall panel 1 is connected... After the strip buckle 22 is initially engaged and positioned with the first splice of another wall panel 1, each set of fixing holes 31 can be precisely coaxially aligned with the connecting holes 41 on the fixing plate 4. Then, the screwing part 5 passes through the aligned fixing holes 31 and connecting holes 41 to form a multi-point mechanical fastening for the two splices. The at least two sets of spaced fixing holes 31 can avoid uneven force caused by single-point fastening, further improve the overall stability of the wall panel 1 after splicing, prevent loosening, displacement or deformation at the splice, and ensure the structural reliability of the wall panel 1 after installation.

[0018] The screwing part 5 can be a self-tapping screw, bolt or rivet. The self-tapping screw has sharp threads that can directly penetrate the material, the bolt needs to be used with a nut, and the rivet is a rod-shaped fastener with a cap. The fixing hole 31 is a hole with threads on the inner wall, and its thread specification is compatible with the selected screwing part 5. The connecting hole 41 is a countersunk hole, that is, one end of the hole has a tapered groove, and the size of the groove matches the head of the screwing part 5. Functionally, the screw fastener 5, as the core fastening element, tightly connects the splicing parts of the two wall panels 1 to the fixing plate 4 by passing through the aligned fixing holes 31 and connecting holes 41. Different types of screw fasteners 5 can adapt to different installation scenarios (e.g., self-tapping screws are suitable for quick installation, bolts are suitable for situations requiring disassembly, and rivets are suitable for permanent fixing). The fixing hole 31 is designed as a threaded hole, which can form a threaded engagement with the screw fastener 5, greatly improving the connection strength and effectively preventing loosening. The connecting hole 41 is designed as a countersunk hole, which allows the head of the screw fastener 5 to be fully embedded in the hole, avoiding protrusion from the surface of the fixing plate 4. This ensures both the flatness and aesthetics after installation and prevents the head of the screw fastener 5 from scratching objects or people, improving safety during use.

[0019] As the core sound insulation component of the wall panel 1, the sound insulation layer 12 can be made of any one of rock wool, glass wool, polyurethane foam, or damping sound insulation board, or a combination of at least two materials. Rock wool is a fibrous structure made from melted natural rock, glass wool is a fluffy material formed by processing ultra-fine glass fibers, polyurethane foam is a porous honeycomb structure, and damping sound insulation board is mostly a multi-layer composite structure (often containing a damping coating and a substrate layer). These materials all have the structural characteristics of being compatible with the thickness of the wall panel 1 and being able to be sandwiched between the base layer 11 and the finishing layer 13. Functionally, the core role of the sound insulation layer 12 is to block or reduce the propagation of sound waves. Different materials achieve sound insulation effects through their respective structural characteristics: rock wool and glass wool absorb sound wave energy through fiber gaps and loose structure, reducing sound wave reflection and penetration; polyurethane foam buffers and dissipates sound waves through its porous structure; the damping sound insulation board converts sound wave vibration energy into heat energy through the viscoelasticity of the damping coating, preventing sound waves from being transmitted through the wall panel 1; and when multiple materials are used in combination, the sound insulation advantages of different materials can be combined to further optimize the sound insulation performance. At the same time, some materials (such as rock wool and glass wool) also have certain fireproof and heat insulation functions, while the damping sound insulation board has good vibration resistance, ultimately ensuring the overall sound insulation effect and safety of the wall panel 1.

[0020] All four sides of the wall panel 1 body have been rounded to form a rounded chamfer structure. The radius of the rounded chamfer is limited to the range of 1mm to 3mm. The chamfer outline is smooth and continuous, without sharp edges, and naturally connects with the side edges of the wall panel 1 body. The overall structure is regular and the size is uniform. Functionally, firstly, the 1mm-3mm rounded chamfer effectively eliminates the sharp right angles on the side edges of wall panel 1, preventing workers from accidentally touching sharp edges and causing scratches, bumps, or other safety hazards during the handling and installation of wall panel 1, thus improving operational safety. Secondly, during the splicing and installation of wall panel 1, the smooth rounded chamfer reduces friction and interference between the side edges of adjacent wall panels 1, making it easier to align wall panels 1 precisely and reducing installation difficulty, while also preventing edge damage caused by the squeezing of right-angled edges. In addition, the rounded transition design makes the overall visual effect of wall panel 1 softer, reducing the harshness of right angles and improving the overall aesthetics of wall panel 1 after installation. Compared to right-angled edges, the rounded chamfer structure is more wear-resistant in daily use and less prone to edge chipping or splintering due to minor collisions, thus extending the service life of wall panel 1.

[0021] Structurally, the elastic seal is positioned between the mating surfaces of the first and second splicing parts. Its shape matches the contours of the mating surfaces of the two splicing parts, and it is mostly a strip structure extending along the length of the splicing part. The material is usually selected from materials with good elasticity and deformation recovery ability (such as rubber, silicone, or elastic sealing foam). It can tightly fit the mating surfaces of the first and second splicing parts, fill any small gaps that may exist on the mating surfaces, and can adapt to deformation during splicing operations without affecting the normal snap-fit ​​and fastening of the two splicing parts. Functionally, the primary function of the elastic seal is to enhance the sealing performance of the splicing joint of the wall panel 1: on the one hand, it can effectively seal the gap between the mating surfaces of the first and second splicing parts, preventing sound waves from penetrating through the gap, further supplementing the sound insulation effect of the sound insulation layer 12, reducing the transmission of external noise or indoor noise, and improving the overall sound insulation performance of the wall panel 1; on the other hand, it can prevent dust, moisture, and other impurities from entering the interior of the wall panel 1 through the splicing gap, preventing the base layer 11 from being damaged by moisture or the sound insulation layer 12 from being affected by dust accumulation, thus extending the service life of the wall panel 1. In addition, the elastic properties of the elastic seal can also act as a buffer when splicing the wall panel 1, reducing the hard contact collision between the first and second splicing parts during the splicing operation and preventing damage to the edge of the splicing part; at the same time, during the long-term use of the wall panel 1, it can adapt to the slight displacement of the splicing part caused by temperature changes or slight vibrations, maintain the stability of the sealing effect, and ensure the reliability of the splicing part of the wall panel 1.

[0022] The process of using a snap-fit ​​quick-assembly soundproof wall panel of this utility model is as follows: Align the second splicing part strip buckle 22 of one wall panel 1 with the first splicing part strip snap groove 21 of another wall panel 1 and insert it so that the elastic sealing parts of the mating surfaces of the two panels fit tightly to complete the splicing and positioning. Then, cover the fixing plate 4 at the fixing hole 31 of the splicing part of the two wall panels 1, ensuring that the countersunk hole of the fixing plate 4 is coaxially aligned with the fixing hole 31. Then, use self-tapping screws, bolts or rivets or other screwing parts 5 to pass through the aligned countersunk hole and fixing hole 31 and tighten them to complete the installation of the two wall panels 1.
