Description

Technical Field

[0001] This utility model relates to the field of sound insulation and heat insulation wall panels, specifically to a honeycomb structure sound insulation and heat insulation wall panel. Background Technology

[0002] In the field of modern architecture, as people's requirements for the quality of living and working environments continue to increase, the sound insulation and thermal insulation performance of wall panels has become a core indicator for measuring building comfort and energy efficiency.

[0003] Honeycomb structure wall panels are a new type of composite material based on biomimetic design (simulating honeycomb structure). Through the sandwich structure of "panel + honeycomb core", it achieves multiple functions such as lightweight, high strength, sound insulation and heat insulation, and is widely used in building walls, partitions, ceilings and other scenarios.

[0004] Existing honeycomb wall panels mostly use hexagonal honeycomb cores with a single aperture, which are insufficient for targeting different frequencies of sound waves, especially low-frequency noise, including mechanical vibration and traffic noise, and have limited blocking effect. At the same time, the rigid connection between the honeycomb core and the panel can easily form a "sound bridge", causing sound waves to be transmitted directly through the connection point, which significantly weakens the sound insulation effect.

[0005] Therefore, it is necessary to invent a honeycomb structure sound insulation and heat insulation wall panel to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a honeycomb structure sound insulation and heat insulation wall panel. By using the partition in the isolation component as a damping sound insulation board, the low-frequency vibration energy can be consumed through the damping layer, which can specifically reduce low-frequency noise such as mechanical vibration and traffic noise. The glass wool sound-absorbing material in the through groove can enhance the absorption of mid-to-high frequency sound waves and achieve multi-band acoustic barrier. At the same time, it reduces the rigid contact between the honeycomb core and the wall, reduces the "sound bridge" effect, and can solve the problems in the prior art, such as the insufficient low-frequency noise barrier of the single-pore honeycomb core, the "sound bridge" formed by the rigid connection between the honeycomb core and the panel leading to poor sound insulation effect, sound leakage through gaps and the impact of air convection on the heat insulation performance.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a honeycomb structure sound insulation and heat insulation wall panel, comprising...

[0008] A wall is used to support the overall device. The inner wall of the wall has an installation groove. A honeycomb module is fixedly installed on the inner wall of the installation groove by an isolation component. The isolation component includes a partition. The partition is a composite structure of a damping layer and a substrate layer. The partition is fixedly connected to the front and rear sides of the honeycomb module. A through groove is opened through the inner wall of the partition.

[0009] An auxiliary component for supporting the wall includes a reinforcing plate fixedly connected to the front and rear sides of the wall, and reinforcing ribs fixedly connected to the inner wall of the reinforcing plate.

[0010] Preferably, the isolation component further includes a sealing member a, which is fixedly connected to the upper and lower sides of the cellular module, and sealing members b are fixedly connected to the left and right sides of the cellular module, with the outer side of the sealing member b fixedly connected to the inner wall of the mounting groove.

[0011] Preferably, the auxiliary component further includes a protrusion, which is fixedly connected to the side of the reinforcing plate near the wall. Multiple sets of grooves are formed on the outer side of the wall, and the protrusion is fitted into the inner wall of the groove.

[0012] Preferably, the reinforcing ribs are configured as a mesh.

[0013] Preferably, the channel is filled with glass wool sound-absorbing material.

[0014] Preferably, both the sealing element a and the sealing element b are made of rubber, and the Shore hardness of the sealing element a and the sealing element b is 60 to 80 A.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] This utility model sets up an isolation component and a honeycomb module to form multiple acoustic barriers: the cavity structure of the honeycomb module itself can reflect and attenuate sound waves, while the glass wool sound-absorbing material filled in the through grooves on the inner side of the partition can further absorb sound waves that penetrate the honeycomb, reducing noise transmission; at the same time, the rubber sealing components a and b can seal the upper, lower and left and right gaps of the honeycomb module, preventing heat loss caused by air convection and enhancing the heat preservation effect; the partition, as a damping sound insulation board, can consume sound wave energy through its own material properties, forming a "double-layer sound insulation" with the honeycomb structure, effectively reducing the impact of the "sound bridge" phenomenon and improving the overall sound insulation.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1 - Figure 3 The honeycomb structure sound insulation and heat insulation wall panel shown includes a wall body 1 and auxiliary components 3;

[0025] Wall 1 supports the entire device, serving as the basic support structure for the entire wall panel and maintaining its stability. The inner wall of wall 1 has mounting grooves 5, on which honeycomb modules 4 are fixedly installed via isolation components 2. These modules are composed of a honeycomb core structure made of aluminum, paper, or composite materials, with pore sizes ranging from 5 to 20 mm. Numerous sealed cavities block airborne sound transmission through sound wave reflection and attenuation, while simultaneously reducing heat conduction by utilizing the low thermal conductivity of the air layer. This forms the basic carrier for the wall panel's sound insulation and heat preservation. Isolation components 2 include partitions 21, which are fixedly connected to the front and rear sides of the honeycomb modules 4, serving as damping and sound-insulating panels. The partitions 21 are a damping layer and... The composite structure of the substrate layer consists of high-density boards, while the damping layer is mainly composed of polymer damping materials, such as butyl rubber, asphalt-based damping adhesive, and polyurethane damping coating. This converts sound wave vibration energy into heat energy, suppresses board resonance, and reduces sound transmission caused by the "sound bridge" phenomenon. Together with the honeycomb module 4, it forms a "double-layer sound insulation". The inner wall of the partition 21 has a through groove 24, which is filled with glass wool sound-absorbing material. The glass wool sound-absorbing material has a porous structure and can absorb sound wave energy through air friction and fiber vibration, specifically weakening mid-to-high frequency noise and compensating for the lack of high-frequency sound insulation in the honeycomb structure.

[0026] Auxiliary component 3 is used to support wall 1. Auxiliary component 3 includes reinforcing plate 31, which is fixedly connected to the front and rear sides of wall 1 as an outer protective structure to improve the impact and pressure resistance of wall 1 and reduce the deformation of wall 1 caused by external force collision. Reinforcing ribs 32 are fixedly connected to the inner wall of reinforcing plate 31. The reinforcing ribs 32 are set in a grid shape and are evenly distributed on the inner wall of reinforcing plate 31. Through cross support, the rigidity and bending resistance of reinforcing plate 31 are improved, and the reinforcing plate 31 is prevented from warping due to its own weight or external force.

[0027] like Figure 2 - Figure 3 As shown, the isolation component 2 also includes a sealing member a22, which is fixedly connected to the upper and lower sides of the honeycomb module 4. Sealing members b23 are fixedly connected to the left and right sides of the honeycomb module 4. The outer side of the sealing member b23 is fixedly connected to the inner wall of the mounting groove 5. Both sealing members a22 and b23 are made of rubber. The Shore hardness of sealing members a22 and b23 is 60-80A. Through the elastic properties of the rubber material, sealing members a22 and b23 seal the gap between the honeycomb module 4 and the mounting groove 5, prevent heat loss caused by air convection, enhance the heat preservation effect, and block the transmission path of sound waves through the gap.

[0028] like Figure 2 - Figure 3 As shown, the auxiliary component 3 also includes a protrusion 33, which is fixedly connected to the side of the reinforcing plate 31 near the wall 1. Multiple sets of grooves 34 are opened on the outer side of the wall 1, and the protrusion 33 is fitted into the inner wall of the groove 34. The protrusion 33 is fitted into the groove 34, which increases the contact area and friction between the reinforcing plate 31 and the wall 1, prevents the reinforcing plate 31 from loosening or sliding relative to the wall 1, and improves the stability of the overall structure. At the same time, the structural fitting provides a positioning reference for the installation of the reinforcing plate 31, ensures the installation accuracy, and simplifies the construction process.

[0029] The working principle of this utility model is as follows: When sound waves act on the surface of the wall panel, the numerous sealed cavities of the honeycomb core in the honeycomb module 4 will reflect and scatter the sound waves, causing some of the sound waves to repeatedly attenuate within the cavities and thus preventing them from directly penetrating the wall panel.

[0030] At the same time, the sound waves will come into contact with the partitions 21 on the front and back sides of the honeycomb. The partitions 21 act as damping and sound insulation boards. The polymer damping layer inside the partitions will generate internal friction through viscoelastic deformation, converting the vibration energy of the sound waves into heat energy for consumption, suppressing the resonance of the board, and weakening the rigid sound transmission caused by the "sound bridge" phenomenon.

[0031] The groove 24 on the partition 21 is filled with glass wool sound-absorbing material, which uses its porous structure to absorb mid-to-high frequency sound waves, such as talking and equipment operation. The sound wave energy is further absorbed through air friction and fiber vibration, forming a dual sound absorption effect of "damping consumption + porous sound absorption".

[0032] The sealing components a22 on the top and bottom sides and b23 on the left and right sides of the honeycomb module 4 are made of rubber. They fill the gaps through elastic deformation, blocking the diffraction and transmission of sound waves through the gaps, thus avoiding the "sound leakage" phenomenon.

[0033] The airflow inside the sealed cavity of the honeycomb module 4 is poor, forming a static air layer. Since air has a low thermal conductivity, it can effectively reduce the transfer of heat through thermal conduction.

[0034] Meanwhile, the rubber sealing components a22 and b23 seal the edge gaps of the honeycomb module 4, preventing cold air from the outside and hot air from the inside from forming convection through the gaps, avoiding heat exchange caused by air flow, and enhancing the heat preservation effect.

[0035] The reinforcing plates 31 on the front and rear sides of the wall 1 and the grid-like reinforcing ribs 32 form a three-dimensional support frame: the reinforcing ribs 32 disperse external forces, such as impact and compression, through the cross structure, and improve the bending resistance of the reinforcing plates 31; the reinforcing plates 31 evenly transmit external forces to the wall 1, avoiding excessive local stress that could lead to deformation.

[0036] The protrusions 33 on the reinforcing plate 31 engage with the grooves 34 on the outer side of the wall 1, increasing the connection strength between the two through mechanical interlocking and preventing the reinforcing plate 31 from loosening with the wall 1.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
