Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, and in particular to an integrated interior partition wall structure. Background Technology

[0002] An interior partition wall is a wall used to divide a single independent space within a building into two independent spaces. Interior partition walls are non-load-bearing and generally require sound insulation. There are many types of interior partition walls, including gypsum board walls, light steel frame gypsum board walls, metal-faced sandwich panel walls, and lightweight wooden frame panels, among others. With the acceleration of urbanization, the construction industry has increasingly higher requirements for construction speed and quality. Under current technology, the construction process for interior partition walls is relatively cumbersome, leading to significant inconvenience, long construction periods, high costs, and poor thermal insulation.

[0003] Therefore, there is an urgent need to design an integrated internal partition wall structure to solve one or more technical problems that are lacking in the existing technology. Utility Model Content

[0019] like Figures 1-2 As shown, this utility model provides an integrated interior partition wall structure, characterized in that it includes: a first sound insulation and heat insulation board 10 and a second sound insulation and heat insulation board 11, the first and second sound insulation and heat insulation boards 11 are arranged at intervals, the top and bottom of the first and second sound insulation and heat insulation boards 11 are respectively fixedly connected together by connectors 13, the top and bottom of the first and second sound insulation and heat insulation boards 11 are respectively connected together by pressing buckles 14, the first and second sound insulation and heat insulation boards 11 each include a decorative surface layer 15, a heat insulation layer 16 disposed on the inner side of each decorative surface layer by hot pressing process, and a sound insulation layer 17 disposed on the inner side of the heat insulation layer 16, the thickness of the decorative surface layer 15 is 5mm-10mm, and the thickness of the heat insulation layer 16 is 30mm-50mm.

[0020] Furthermore, the decorative surface layer 15 is a high-density fiberboard or a composite decorative board, and the side of the decorative surface layer 15 facing away from the insulation layer 16 is also provided with a UV coating.

[0021] Furthermore, the sound insulation layer 17 includes: a double-layer sound insulation felt 171 and an air cavity 172, wherein the double-layer sound insulation felt 171 and the air cavity 172 are arranged alternately, and the air cavity 172 is honeycomb-shaped.

[0022] Furthermore, the adjacent sidewalls of the first and second sound insulation and heat preservation boards 11 are alternately provided with protruding tenons and recessed mortises.

[0023] Furthermore, the thickness of the air cavity 172 is 10mm-15mm.

[0024] Specifically, the first sound insulation board 10 and the second sound insulation board 11 have the same structure. The following description uses the first sound insulation board 10 as an example. The first sound insulation board 10 includes a decorative surface layer 15. This decorative surface layer 15 is made of high-density fiberboard, which is a type of board made from wood fiber or other plant fibers, pressed under high temperature and pressure by applying urea-formaldehyde resin or other synthetic resins. It has high density and a fine structure, high strength, impact resistance, good water resistance, and a smooth, easy-to-clean surface. Alternatively, it can be made of composite decorative board, such as wood grain PVC board. The overall thickness of the decorative surface layer 15 is preferably 5-10mm, and the specific thickness can be determined according to the application requirements. To ensure the wear resistance of the decorative surface layer 15, a UV coating is applied to its surface, giving it both decorative and wear-resistant properties. An insulation layer 16 is bonded to the inside of the decorative surface layer 15 using a hot-pressing process. This insulation layer 16 can be made of extruded polystyrene board, closed-cell polyurethane foam, or rock wool board, etc. In this embodiment, extruded polystyrene board is preferred to control costs. The overall thickness of the insulation layer 16 is preferably 30-50mm, depending on actual usage requirements. A sound insulation layer 17 is provided inside the insulation layer 16. This sound insulation layer 17 consists of two layers of sound insulation felt 171 and an air cavity 172. The air cavity 172 is located between the two layers of sound insulation felt 171. Made of fiberglass, polyester fiber, or rubber-based composite materials, the single-layer sound insulation felt 171 has a thickness of 3-5mm, achieving a density of ≥2kg / m². During use, it dissipates sound energy through inter-fiber friction and air damping, absorbing mid-to-high frequency (500Hz-4000Hz) sound waves to ensure sound insulation. The air cavity 172 is divided into a honeycomb structure by a keel, which divides the air cavity 172 into small units, thus preventing sound waves from forming a "sound bridge" through continuous cavities. In this embodiment, the thickness of the air cavity 172 is 10-15mm. The air cavity 172 can be used to block the vibration of low-frequency sound waves (20Hz~500Hz). The sound insulation material is transmitted by utilizing the elastic buffering effect of air to reduce sound wave energy. In actual use, the sound wave needs to penetrate the sound insulation felt 171, the air cavity 172, and the sound insulation felt 171 on the other side. After multiple attenuations, the sound pressure level is significantly reduced, and the overall sound insulation volume is ≥45dB. The setting of the air cavity 172 not only ensures the sound insulation effect but also reduces the overall weight of the board, achieving lightweighting. The top and bottom of the first sound insulation board 10 and the second sound insulation board 11 are fixed together by C-shaped connectors 13. At the same time, the top and bottom of the two sound insulation boards are further fixed by pressing buckles 14, so that the two sound insulation boards form a whole.

[0025] It should be noted that two sound insulation boards are used to ensure sound insulation effect; if the requirement is lower, only one sound insulation board can be used.

[0026] To facilitate the installation of sound insulation panels, tenons and mortises are provided on all four sides of the first and second sound insulation panels 11. The tenons are located on one side, and the mortises are located on the adjacent side. This allows for easy and quick installation of other sound insulation panels by simply aligning the tenons with the mortises and inserting them. In addition, to avoid gaps between multiple sound insulation panels on the same plane, sealing strips can be installed between adjacent sound insulation panels. When adjacent sound insulation panels are joined together, the gaps are filled by squeezing the sealing strips, further improving the sound insulation effect.

[0027] In summary, the structural design of this application enables the interior partition wall to possess decorative, sound insulation, and thermal insulation properties. Furthermore, the inclusion of the air cavity 172 achieves both lightweighting and sound insulation. The composite structure of the sound insulation felt and the honeycomb air cavity effectively attenuates mid-to-high frequency sound waves and blocks the transmission of low-frequency sound waves, achieving excellent broadband sound insulation. Simultaneously, the structural cost is low, and the use of tenons and mortises enables rapid assembly, meeting the rapid construction requirements of prefabricated buildings.

[0028] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
