[0026] With the acceleration of urbanization and the increase in population density, noise pollution has become one of the important factors affecting people's quality of life. The existing wall sound insulation structure mainly uses materials such as sound insulation cotton to fill the partition wall. Although these materials have a certain sound insulation effect, they are not good at isolating low-frequency noise.

[0027] In order to solve this technical problem, the utility model provides a wall sound insulation structure, aiming to provide a wall sound insulation structure using phononic crystals for cavity filling.

[0028] See also Figure 1 The wall sound insulation structure includes: a building partition wall 10, a reinforcing rib 22 and at least two sound insulation components 20.

[0029] The building partition wall 10 is used to be installed in the indoor space of a building, and a cavity 11 is provided in the building partition wall;

[0030] The reinforcing rib 22 is installed in the cavity 11, and the opposite sides of the reinforcing rib 22 are connected to the opposite walls of the cavity;

[0031] Each sound insulation member is connected between the cavity wall of the cavity 11 and one side of the reinforcing rib, and the sound insulation member is a phononic crystal structure.

[0032] The building partition wall 10 is the main part of the wall sound insulation structure, which is used to be installed in the indoor space of the building to separate different functional areas. The building partition wall 10 is provided with a cavity 11 inside, which provides space for the installation of the sound insulation member 20.

[0033] The reinforcing rib 22 is a component installed in the cavity 11, and its two opposite sides are connected to the two opposite walls of the cavity 11. The function of the reinforcing rib 22 is to enhance the structural stability of the building partition wall 10 and prevent the partition wall from being structurally weakened due to the installation of the sound insulation member 20. At the same time, the existence of the reinforcing rib 22 also provides a fixing point for the sound insulation member 20, ensuring that the sound insulation member 20 can be stably installed in the cavity 11.

[0034] The sound insulation 20 is a key component of the present invention, which is connected between the cavity wall of the cavity 11 and one side of the reinforcing rib 22. The sound insulation 20 adopts a phononic crystal structure, and through the periodic arrangement of the phononic crystals, it can produce specific reflection, refraction and scattering effects on sound waves, thereby achieving effective isolation of low-frequency noise. The setting of the phononic crystal structure can be optimized according to the noise frequency to be isolated to achieve the best sound insulation effect.

[0035] In the technical solution provided by the utility model, a sound insulation piece is filled in the cavity of the wall sound insulation structure. The material of the sound insulation piece is a phononic crystal structure. The phononic crystal can generate a band gap through two mechanisms, Bragg scattering and local resonance, within a specific frequency range through its periodic structure, and effectively scatter and interfere with sound waves, thereby achieving filtering and sound insulation of sound waves of specific frequencies.

[0036] Combination Figure 1 As shown, in the embodiment of the present invention, the thickness of the sound insulation member 20 is 0.5 mm-5 mm.

[0037] In this example, the thickness of the sound insulation member 20 is set within the range of 0.5 mm to 5 mm, preferably 3 mm. The thickness of the sound insulation member 20 directly affects its sound insulation performance. Thicker sound insulation members can generally provide better sound insulation effects because they can more effectively absorb and block the propagation of sound waves. However, too thick sound insulation members will increase material costs and installation difficulties, and may also affect the structural stability of the building partition wall 10. When determining the thickness of the sound insulation member 20, the characteristics of the phononic crystal structure must also be considered. The scattering and interference effects of the periodic structure of the phononic crystal on sound waves are related to its physical size.

[0038] Combination Figure 1As shown, in an embodiment of the present invention, a plurality of sound insulation members 20 are provided, both ends of each reinforcement rib 22 are connected to corresponding adjacent plurality of sound insulation members 20, and the plurality of sound insulation members 20 are arranged in an array in an extension direction of the building partition wall 10.

[0039] In this example, the array-like spacing arrangement of the sound insulation members 20 is intended to further improve the overall sound insulation effect of the wall sound insulation structure through the synergistic effect of multiple sound insulation members. This arrangement allows sound waves to pass through the building partition wall 10 through the continuous action of multiple sound insulation members, thereby achieving a deeper level of sound wave attenuation.

[0040] The two ends of the reinforcing rib 22 are connected to the adjacent sound insulation member 20. This arrangement not only provides a stable support point for the sound insulation member, but also helps to evenly distribute the sound pressure borne by the sound insulation member, reduce local stress concentration, and extend the service life of the sound insulation member. At the same time, the connection method of the reinforcing rib 22 and the sound insulation member 20 also helps to form an acoustic barrier, further enhancing the isolation effect of sound waves.

[0041] The spacing arrangement of the sound insulation members 20 also takes into account the extension direction of the building partition wall 10, ensuring the consistency of the sound insulation effect throughout the entire partition wall. This arrangement allows the building partition wall to provide the same level of sound insulation performance in different areas, whether in the center or at the edge of the partition wall, and can effectively block noise transmission.

[0042] Combination Figure 1 As shown, in the embodiment of the present utility model, the sound insulation member 20 is made of a phononic crystal composed of copper, steel, iron, silver or gold;

[0043] And / or, the length of each sound insulation member 20 is in the range of 50 mm to 60 mm, and the width of each sound insulation member is in the range of 50 mm to 60 mm;

[0044] And / or, the shape of the phononic crystal structure is square, circular, rhombus or elliptical.

[0045] In this example, the sound insulation 20 is made of phononic crystals made of metal materials such as copper, steel, iron, silver or gold, which are selected for their excellent acoustic properties and structural stability. Metal phononic crystals can effectively reflect and scatter sound waves, especially in the low frequency range, due to their high density and good elastic modulus, which makes them ideal for wall sound insulation structures. In addition, the durability and corrosion resistance of metals also help to improve the service life and maintenance cost of the sound insulation.

[0046] The length and width of the sound insulation member 20 are both set within the range of 50 mm to 60 mm, preferably 55 mm, and this size selection is intended to balance the sound insulation effect and the utilization efficiency of the internal space of the building partition wall 10. Sound insulation members of this size range can provide sufficient surface area to achieve effective sound wave scattering, while maintaining the compactness of the structure to adapt to cavities 11 of different sizes.

[0047] The shape of the phononic crystal structure is set to be square, circular, diamond or elliptical. Phononic crystal structures of different shapes can produce different scattering and interference effects on sound waves, thereby optimizing sound insulation performance. For example, square and diamond structures may provide stronger reflection effects at certain frequencies, while circular and elliptical structures may help reduce the focusing effect of sound waves and achieve a more uniform sound insulation effect.

[0048] Combination Figure 1 As shown, in the embodiment of the present utility model, a plurality of reinforcing ribs are provided, and the plurality of reinforcing ribs 22 are arranged at intervals in the extension direction of the building partition wall 10 .

[0049] In this example, multiple reinforcement ribs 22 are provided, and the reinforcement ribs 22 are provided at intervals in the extension direction of the building partition wall 10, in order to enhance the overall stability and bearing capacity of the wall sound insulation structure. By arranging reinforcement ribs at certain intervals inside the partition wall, the pressure caused by sound waves can be effectively dispersed and transmitted, and the local stress on the sound insulation member 20 can be reduced, thereby protecting the phononic crystal structure from damage and extending its service life.

[0050] The spacing of the reinforcing ribs 22 also helps to optimize the acoustic performance inside the building partition wall 10. By rationally planning the positions of the reinforcing ribs, it is possible to avoid the resonance of sound waves inside the partition wall, reduce the propagation path of the sound waves, and further improve the sound insulation effect.

[0051] Combination Figure 1 As shown, in the embodiment of the present invention, the sound insulation member further includes a protective layer 21 , and at least two protective layers 21 are provided, and each protective layer 21 is coated on a surface of the sound insulation member 20 .

[0052] In this example, the protective layer 21 is provided to protect the sound insulation member 20 of the phononic crystal structure, extend its service life, and provide additional sound insulation effect. The protective layer 21 is composed of at least two layers, which are coated on the surface of the sound insulation member 20, which can be the front and back of the sound insulation member, or a protective layer is also provided on the side as needed. The protective layer 21 will be made of wear-resistant, corrosion-resistant, and anti-aging materials, such as acrylic resin, plastic film or metal coating, to ensure that the sound insulation member 20 can resist the erosion of environmental factors and maintain its sound insulation performance during long-term use.

[0053] Combination Figure 1As shown, in the embodiment of the present utility model, the material of the protective layer 21 is one of polyurea, acrylic resin or styrene-butadiene resin;

[0054] And / or, the thickness of the protective layer 21 is in the range of 0.2 mm to 2 mm.

[0055] In this example, the material of the protective layer 21 is selected from polyurea, acrylic resin or styrene-butadiene resin, all of which have good wear resistance, corrosion resistance and anti-aging performance. The thickness of the protective layer 21 is set in the range of 0.2 mm to 2 mm, preferably 1 mm, to ensure that the protective layer can provide sufficient protection, while avoiding the increase in the overall weight and cost of the sound insulation 20 due to an overly thick protective layer. A thinner protective layer can effectively reduce the impact on the acoustic performance of the sound insulation 20 while maintaining the lightness of the wall sound insulation structure, while a thicker protective layer provides stronger wear resistance and impact resistance, and is suitable for vulnerable wall locations.

[0056] Combination Figure 1 As shown, in the embodiment of the present utility model, the wall sound insulation structure further includes an adhesive 23 , which is coated on both sides of the reinforcing rib 22 and adhered to the protective layer 21 .

[0057] In this example, the adhesive 23 plays a vital role in the wall sound insulation structure. It is applied on both sides of the reinforcing rib 22 and firmly adheres the reinforcing rib 22 to the protective layer 21 of the sound insulation member 20. The selection of the adhesive 23 fully considers its compatibility and adhesion with the reinforcing rib 22 and the protective layer 21 to ensure the stability and durability of the entire wall sound insulation structure.

[0058] The adhesive 23 is usually made of materials with high-strength adhesive properties, such as epoxy resin, polyurethane glue or acrylic glue, which can adapt to different environmental conditions and provide a durable adhesive effect. The adhesive 23 should also have good flexibility and anti-aging properties to adapt to thermal expansion and contraction or mechanical vibration that the building partition wall 10 may encounter.

[0059] Combination Figure 1 As shown, in the embodiment of the present utility model, the material of the building partition wall 10 is one of gypsum board, calcium silicate board or calcium silicate board.

[0060] In this example, the material of the building partition wall 10 is selected from one of gypsum board, calcium silicate board or calcium silicate board, preferably gypsum board, which is widely used in the construction field due to its light weight, high strength, good sound insulation and heat insulation performance. Gypsum board is easy to process, while calcium silicate board and calcium silicate board are preferred materials in modern buildings due to their excellent fire resistance and durability.

[0061] The selection of these materials as the material of the building partition wall 10 not only meets the basic functional requirements of the wall sound insulation structure, but also takes into account the convenience and economy of construction. The lightweight characteristics of these materials help to reduce the overall weight of the building, while the good thermal insulation performance helps to improve the energy efficiency of the building.

[0062] Combination Figure 1 As shown, in an embodiment of the present utility model, the wall sound insulation structure further includes a finishing layer 12 , and the finishing layer 12 is arranged on the outer side of the building partition wall 10 .

[0063] In this example, the finishing layer 12 can be made of putty, latex paint, inorganic coating and other materials, with a thickness of 0.2mm-2.0mm, preferably 1mm. The finishing layer 12 is tightly combined with the building partition wall 10 to avoid affecting the sound insulation effect due to improper coating, while protecting the building partition wall 10 and making the indoor environment more beautiful.

[0064] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
