Description

Technical Field

[0001] This utility model relates to the field of partition wall technology, and in particular to a prefabricated partition wall structure. Background Technology

[0002] Prefabricated construction is a major trend in the future development of the construction industry. It aims to gradually solve problems inherent in traditional construction, such as numerous quality defects, high wastage, inconsistent quality, outdated wet construction methods, environmental pollution, low efficiency, slow construction periods, and high labor costs. Building walls, characterized by large floor areas, high material performance requirements, and stringent construction quality standards, are crucial components for functional zoning and structural division in buildings, and are also a key focus of prefabricated construction. Therefore, resolving wall issues is key to improving prefabricated building materials, enhancing construction efficiency, and raising product quality.

[0003] CN110439150A discloses a modular wall panel and prefabricated wall system suitable for ultra-large spaces, enabling rapid wall installation; CN221481119U discloses a prefabricated wall structure that can be quickly installed, fixed, or disassembled and can be repeatedly reused. However, although the above-mentioned prefabricated walls can achieve rapid installation and disassembly of prefabricated partitions, they are constrained by the law of mass, making it difficult to control the wall thickness and weight while meeting high sound insulation requirements, thus failing to simultaneously achieve high sound insulation and a lightweight effect for prefabricated walls.

[0004] Therefore, while meeting the requirements for rapid installation and disassembly of prefabricated partition walls, it is still necessary to develop a new type of prefabricated partition wall structure that can combine high sound insulation with lightweight and thin design. Summary of the Invention

[0019] Furthermore, the metamaterial layer is composed of an array of several Helmholtz resonant cavity units, each of which consists of several arrayed resonant cavities.

[0020] Preferably, the Helmholtz resonant cavity unit consists of 6×6 arrayed resonant cavities; wherein, every 3×3 resonant cavities form a sub-unit, and 4 sub-units form a Helmholtz resonant cavity unit.

[0021] Furthermore, each of the resonant cavities consists of a cavity and concentrically arranged embedded tubes.

[0022] Furthermore, in each subunit, the cavity width of the resonant cavity is the same, preferably 15 mm.

[0023] Furthermore, the inner diameter and length of the embedded tube are not equal, with the inner diameter ranging from 3 to 12 mm and the length ranging from 2 to 31 mm.

[0055] Example 1:

[0056] This embodiment provides a prefabricated partition wall structure, which includes a sound insulation module 1 and a decorative module 2.

[0057] like Figure 1 As shown, the sound insulation module 1 of this embodiment includes a stiffness control layer 11, a composite damping control layer 12, a sound absorption layer 13, a composite sound insulation control layer 14, and a surface metal plate 15, which are arranged layer by layer.

[0058] The decorative module 2 of this embodiment includes a first decorative panel 21 disposed on the outer layer of the stiffness control layer 11, a second decorative panel 22 disposed on the outer layer of the surface metal plate 15, and a frame 23 disposed on the side of the sound insulation module 1.

[0059] The sound insulation module 1 of this implementation integrates a stiffness control layer 11, which has fireproof, heat insulation, moisture resistance and partition wall stiffness control functions; a damping control layer 12, which has sound energy dissipation function; a sound absorption layer 13, which has sound absorption function; and a composite sound insulation control layer 14, which has excellent sound insulation function. This achieves excellent sound insulation and noise reduction effect. Combined with the decoration module 2, a new type of prefabricated partition wall structure that takes into account both high sound insulation and thinness is finally obtained.

[0060] Example 2:

[0061] This embodiment provides a prefabricated partition wall structure, specifically including a sound insulation functional module 1 and a decorative module 2, each of which has a specific sorting position.

[0062] like Figure 1-2 As shown, the sound insulation module 1 of this embodiment includes a stiffness control layer 11, a composite damping control layer 12, a sound absorption layer 13, a composite sound insulation control layer 14, and a surface metal plate 15, arranged layer by layer. Specifically, the stiffness control layer 11 of this embodiment is composed of a calcium silicate board 111 and a first metal plate 112, with a total thickness of 20 mm, and mainly serves to control the stiffness of the partition wall, providing fire resistance, heat insulation, sound insulation, moisture resistance, and overall wall stiffness. The calcium silicate board 111 has a thickness of 19.5 mm, and the first metal plate 112 is a steel plate with a thickness of 0.5 mm.

[0063] In this embodiment, the composite damping control layer 12 consists of a rubber plate 121 and a second metal plate 122, with a total thickness of 15 mm, and mainly serves to dissipate sound energy. The rubber plate 121 can be made of 14.7 mm thick butyl rubber, and the second metal plate 122 has a thickness of 0.3 mm.

[0064] In this embodiment, the sound-absorbing layer 13 includes a cavity 131 and a metamaterial layer 132. The cavity 131 has a thickness of 5 mm, and the metamaterial layer 132 has a thickness of 35 mm, for a total thickness of 40 mm. The cavity 131 and the metamaterial layer 132 work together to achieve synergistic sound absorption. The metamaterial can be made of materials such as metal, polymer, or porous cotton, depending on the requirements.

[0065] like Figure 3-5 As shown, the metamaterial layer 132 in this embodiment is composed of an array of Helmholtz resonant cavity units. Each Helmholtz resonant cavity unit consists of 6×6 arrayed resonant cavities 1321. Each subunit consists of 3×3 resonant cavities 1321, and 4 subunits form a Helmholtz resonant cavity unit. Each resonant cavity 1321 consists of a cavity body 1322 and concentrically arranged inner tubes 1323. In each subunit, the cavity body 1322 of the resonant cavity 1321 has the same width, 15 mm; the inner diameter and length of the inner tube 1323 are not equal, ranging from 3-12 mm in diameter and 2-31 mm in length. The Helmholtz resonant cavity unit, through the geometric matching design of the cavity and tube, can be precisely tuned to the target frequency (especially effective for low frequencies below 500Hz), making up for the shortcomings of traditional porous materials in low-frequency sound absorption. It is suitable for scenarios that require targeted solutions to specific low-frequency noise (such as traffic, mechanical equipment or air conditioning system noise).

[0066] Figure 4 The parameters of resonant cavities 1-9 of the 1321 are summarized as follows:

[0067]

The honeycomb aluminum plate 141 is composed of several regular hexagonal array structures with a side length of 5 mm and a thickness of 10.7 mm. The third metal plate 142 is a steel plate with a thickness of 0.3 mm.

[0069] In this embodiment, the thickness of the surface metal plate 15 is 1 mm.

[0070] The decorative module 2 in this embodiment includes a first decorative panel 21 disposed on the outer layer of the rigidity control layer 11, a second decorative panel 22 disposed on the outer layer of the surface metal plate 15, and a frame 23. The first decorative panel 21 and the second decorative panel 22 in this embodiment are both 6 mm thick. The first decorative panel 21 and the second decorative panel 22 can be made of materials such as plywood, solid wood, PVC board, aluminum alloy plate, or stone, depending on the actual scenario requirements. The frame 23 is located at the side edge of the sound insulation module 1 and is used to assist in fixing the various components of the sound insulation module 1. The thickness of the frame 23 is equal to the overall thickness of the sound insulation module 1.

[0071] The prefabricated partition wall structure in this embodiment integrates the sound insulation module 1 and the decorative module 2, achieving both high sound insulation and a thin profile. The overall thickness is approximately 100 mm, and the overall surface density (excluding the decorative module 2) is approximately 37 kg / m³. 2 It can achieve a sound insulation of approximately 48 dB.

[0072] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
