Description

Technical Field

[0001] This application relates to the field of building walls, and more specifically, to a soundproof structural wall panel for residential unit partition walls. Background Technology

[0002] With the development of society and economy and the improvement of people's living standards, people have put forward increasingly higher requirements for the acoustic comfort of their residences. Among them, the sound insulation performance of the partition walls is particularly critical, as it is directly related to the privacy and tranquility of living.

[0003] Low-frequency sound waves (such as those from elevator operation, household appliance vibrations, and the low-frequency portion of conversation) have longer wavelengths and stronger penetrating power. Traditional lightweight wall materials are easily affected by these waves, causing resonance and sound transmission, resulting in a significant decrease in sound insulation. Most existing soundproofing materials and structures are effective against high-frequency noise, but their attenuation of low-frequency noise is very limited. According to the "mass law" in traditional acoustics, achieving ideal sound insulation often requires increasing the surface density and thickness of the walls. Therefore, in conventional designs, to achieve effective sound insulation, the thickness of the partition walls between apartments typically needs to reach 200 mm or even more. This practice directly encroaches on valuable interior space, reducing the usable floor area ratio and making it unacceptable to modern homeowners who prioritize space utilization. Utility Model Content

[0004] This application provides a sound insulation structural wall panel for residential partition walls, which can improve the sound insulation effect of partition walls.

[0005] Specifically, this application is implemented through the following technical solution: This application provides a sound insulation structural wall panel for residential unit partition walls, comprising: Two damping sound insulation panels positioned opposite each other; A keel frame is disposed between the two damping and sound-insulating panels; The keel frame includes a horizontal keel and a vertical keel arranged in the same direction as the damping sound insulation plate. The vertical keel includes a first vertical keel and a second vertical keel. The horizontal keel is connected between the first vertical keel and the second vertical keel. The damping sound insulation plate and the keel frame form a first chamber, which is filled with sound-absorbing cotton. The horizontal keel is fixedly connected to the vertical keel via a damping connecting strip, the damping connecting strip comprising a metal layer and a damping layer fixed to one side of the metal layer.

[0006] Optionally, the transverse keel includes multiple sets, one set including an adjacent first transverse keel and a second transverse keel, wherein the first transverse keel and the first vertical keel are fixedly connected by the damping connecting strip. The second horizontal keel and the second vertical keel are fixedly connected by the damping connecting strip.

[0007] Optionally, the metal layer of the damping connecting strip is fixedly connected to the horizontal keel, and the damping layer is fixedly connected to the vertical keel.

[0008] Optionally, the metal layer is stamped with an anchoring groove facing the damping layer, and the damping layer is embedded in the anchoring groove by a hot pressing process; The metal layer has multiple threaded connection holes on the side facing the vertical keel, and the vertical keel is equipped with multiple threaded connectors. The threaded connectors penetrate the damping layer and are threadedly connected to the threaded connection holes.

[0009] Optionally, the anchoring groove is a rhomboid pyramidal groove.

[0010] Optionally, the metal layer is a low-carbon steel layer; and / or The damping layer is an asphalt damping layer; and / or The metal layer and the damping layer are connected by an adhesive layer, which is an epoxy resin structural adhesive layer.

[0011] Optionally, each of the transverse keels includes sub-transverse keels I and sub-transverse keels II distributed at intervals along a straight line, wherein the sub-transverse keel I is fixedly connected to the first vertical keel, and the sub-transverse keel II is fixedly connected to the second vertical keel; The transverse keel also includes a keel connector that spans the gap between the sub-transverse keel I and the sub-transverse keel II.

[0012] Optionally, each of the transverse keels includes a plurality of keel connectors, which are staggered on both sides of the transverse keel.

[0013] This application provides a sound insulation structure wall panel for residential unit partitions. High-density damping sound insulation panels on both sides serve as the main mass layers, effectively reflecting and dissipating sound energy. The cavities formed by these panels and the internal keel frame, with air layers acting as springs, are specifically designed to block the propagation path of mid-to-low frequency noise. Sound-absorbing cotton filling the cavities further absorbs sound energy and suppresses cavity resonance, thereby synergistically improving overall sound insulation. The metal layer of the damping connecting strip provides a robust base for the connection with the horizontal and vertical keels, ensuring mechanical strength and structural stability at the joints. Its damping layer introduces a high-internal-loss elastic medium between the metal layer and the vertical keel. When vibrations are transmitted through the keel frame, the damping layer effectively converts mechanical vibration energy into heat energy and dissipates it, thus short-circuiting the "sound bridge" formed by the keel, significantly weakening vibration transmission and improving the overall sound insulation effect.

When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0017] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly.

[0018] refer to Figure 1 , Figure 2 and Figure 3This application provides a sound insulation structure wall panel for a residential partition wall, including a damping sound insulation panel 100 and a keel frame 200. Two damping sound insulation panels 100 are included and arranged opposite each other. The keel frame 200 is disposed between the two damping sound insulation panels 100. The keel frame 200 includes a horizontal keel 210 and a vertical keel 220 arranged in the same direction as the damping sound insulation panels 100. The vertical keel 220 includes a first vertical keel 221 and a second vertical keel 222. The horizontal keel 210 connects the first vertical keel 221 and the second vertical keel 222. The damping sound insulation panels 100 and the keel frame 200 enclose a first chamber A, which is filled with sound-absorbing cotton a1. Figure 4 , Figure 5 and Figure 6 The horizontal keel 210 is fixedly connected to the vertical keel 220 via a damping connecting strip 300. The damping connecting strip 300 includes a metal layer 310 and a damping layer 320 fixed to one side of the metal layer 310.

[0019] In this application, firstly, the high-density damping sound insulation panels 100 on both sides serve as the main mass layer, effectively reflecting and dissipating sound energy. The cavity formed by these panels and the internal keel frame 200, with its air layer acting as a spring, specifically targets the blocking of mid-to-low frequency noise propagation paths. The sound-absorbing cotton a1 filled within the cavity further absorbs sound energy and suppresses cavity resonance, thereby synergistically improving the overall sound insulation. The metal layer 310 of the damping connecting strip 300 provides a robust foundation for the connection between the transverse keel 210 and the vertical keel 220, ensuring mechanical strength and structural stability at the joint. Its damping layer 320 introduces a high-internal-loss elastic medium between the metal layer 310 and the vertical keel 220. When vibration is transmitted through the keel frame 200, the damping layer 320 effectively converts mechanical vibration energy into heat energy and dissipates it, thus short-circuiting the "sound bridge" formed by the keel, significantly weakening vibration transmission and improving the overall sound insulation effect.

[0020] The aforementioned efficient composite structure achieves excellent sound insulation performance with a relatively thin wall thickness. For example, a 12mm+60mm+12mm structural system can achieve the sound insulation effect of a traditional thick wall, thus significantly increasing usable indoor space. The wall panels and framing components used in this structure are suitable for custom-made and numbered in the workshop, followed by modular assembly on-site. This method reduces material waste and construction debris, aligning with the development direction of green building.

[0021] The specific construction process includes: firstly, processing the keel and damping sound insulation board 100 according to the layout and size; installing and assembling the keel frame 200 on site; installing the damping sound insulation board 100 on both sides, forming the first cavity structure in the middle; then filling the first cavity with absorbent cotton, such as centrifugal glass wool; and finally sealing the wall as a whole with sealant and shock-absorbing pads.

[0022] In one embodiment, the transverse keel 210 comprises multiple sets, one set including adjacent first transverse keels 210 and second transverse keels 212. The first transverse keel 210 is fixedly connected to the first vertical keel 221 via a damping connecting strip 300; the second transverse keel 212 is fixedly connected to the second vertical keel 222 via a damping connecting strip 300. This staggered arrangement ensures that the vertical keels 220 on both the left and right sides can receive direct transverse support through a portion of the transverse keels 210. This allows the load to be distributed and transferred to the structural systems on both sides, thus maintaining the overall stiffness and stability of the keel frame 200 even with the introduction of flexible sound insulation elements, effectively preventing structural instability. Furthermore, this arrangement structurally disrupts the continuous propagation path of vibration through the keel system. After the sound wave vibration is transmitted from one vertical keel 220 to a horizontal keel 210 through the damping connecting strip 300, if it wants to continue to propagate to the other side of the wall, it must pass through another damping connecting strip 300 again, which significantly improves the effect of blocking the "sound bridge".

[0023] In one embodiment, the metal layer 310 of the damping connecting strip 300 is fixedly connected to the horizontal keel 210, and the damping layer 320 is fixedly connected to the vertical keel 220. This directional connection method is very suitable for construction scenarios where installation is performed from the outside of the vertical keel 220. During operation, the fastener can be driven in from one side of the vertical keel 220, passing through the damping layer 320 in sequence and finally anchored in the metal layer 310. This connection method achieves two advantages: first, a strong metal-to-metal rigid connection can be achieved between the metal layer 310 and the horizontal keel 210, for example, by welding or screw locking, ensuring connection strength; second, the middle damping layer 320 effectively isolates the vibration transmission between the vertical keel 220 and the metal layer 310, cutting off the sound bridge.

[0024] refer to Figure 7In one embodiment, the metal layer 310 has an anchoring groove 311 stamped on it facing the damping layer 320, and the damping layer 320 is embedded into the anchoring groove 311 by a hot-pressing process. Multiple threaded connection holes 312 are provided on the side of the metal layer 310 facing the vertical keel 220, and multiple threaded connectors are installed on the vertical keel 220. The threaded connectors penetrate the damping layer 320 and are threadedly connected to the threaded connection holes 312. The anchoring groove 311 on the metal layer 310 provides an embedding space for the damping layer 320. The hot-pressing process embeds the damping layer 320 material into the groove, forming a strong mechanical interlock, which greatly enhances the bonding strength between the metal layer 310 and the damping layer 320 and prevents interlayer peeling. Simultaneously, the threaded connection holes 312 provide precise and reliable anchoring points for the connection on the vertical keel 220 side. The threaded connectors can be screwed into these holes, achieving mechanical locking between the metal parts. This results in high connection strength and reliability, making it suitable for construction applications with high structural safety requirements. To further enhance the bonding strength, a thermosetting adhesive can be applied to the surface of the metal layer 310 before hot pressing.

[0025] In one embodiment, the anchoring groove 311 is a rhomboid pyramidal groove. This shape provides uniform and good resistance to shear stress from any direction, effectively preventing relative slippage between the damping layer 320 and the metal layer 310.

[0026] In one embodiment, the metal layer 310 is a low-carbon steel layer; and / or, the damping layer 320 is an asphalt damping layer; and / or, the metal layer 310 and the damping layer 320 are connected by an adhesive layer, which is an epoxy resin structural adhesive layer. The low-carbon steel layer possesses good stamping performance and structural strength, is easy to process into the required anchor grooves 311 and threaded holes, and has low cost. The asphalt damping layer 320, as a typical high-consumption material, has excellent vibration damping characteristics, meaning it can convert mechanical vibration energy into heat energy. The epoxy resin structural adhesive layer provides extremely high bonding strength and durability, further strengthening the connection between the metal layer 310 and the damping layer 320, ensuring that they maintain their integrity during long-term use.

[0027] refer to Figure 3In one embodiment, each transverse keel 210 includes sub-transverse keels I 210a and II 210b spaced apart along a straight line. Sub-transverse keels I 210a are fixedly connected to a first vertical keel 221, and sub-transverse keels II 210b are fixedly connected to a second vertical keel 222. The transverse keel 210 also includes a keel connector 210c spanning the gap between sub-transverse keels I 210a and II 210b. This embodiment divides a single transverse keel 210 into two segments, which are then connected by the keel connector 210c. Breaking the transverse keel 210 in the middle physically interrupts the path of vibration propagation along the longitudinal direction of the transverse keel 210, fundamentally preventing the direct formation of a sound bridge through the transverse keel 210. The keel connector 210c spans and is fixed to the two transverse keels 210. Its main function is to ensure that the transverse keels 210 can still work together after being disconnected, maintaining the necessary structural stability and overall rigidity, without bearing the main vibration transmission function.

[0028] In one embodiment, each transverse keel 210 includes multiple keel connectors 210c, which are staggered on both sides of the transverse keel 210. This staggered distribution allows forces from different directions to be transmitted and dispersed more evenly, avoiding stress concentration. This arrangement better constrains the two keel segments, preventing torsion or lateral instability, thereby further enhancing the integrity and stability of the keel frame 200 while preventing acoustic bridges.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
