[0002] With the acceleration of urbanization and the continuous increase in building density, noise pollution has become a common concern for urban residents. Although traditional brick walls or concrete walls have good sound insulation, they also bring inconveniences such as heavy weight and cumbersome construction. Especially for interior space design, the requirements for functionality and aesthetics are increasing day by day. Therefore, the development of a new type of partition board that can not only meet the sound insulation needs, but also has lightweight, environmentally friendly and easy to install has become the focus of the industry. Such a lightweight partition board with sound insulation function has come into being.

[0003] Utility model announcement number CN221524050U discloses a sound-insulating lightweight partition board, comprising a base plate, a mounting plate disposed on one side of the base plate, a mounting groove formed on a sidewall of the mounting plate adjacent to the base plate, a first sound-absorbing cotton board disposed at the bottom of the mounting groove, a gel board disposed within the mounting groove on one side of the first sound-absorbing cotton board, and two slots formed at the opening of the mounting groove.

[0004] When using the above technical solution, first, the first sound-absorbing cotton board, the gel board and the second sound-absorbing cotton board can be placed in the installation groove. Then, when installing the partition board with screws, the first sound-absorbing cotton board, the gel board and the second sound-absorbing cotton board can be simultaneously installed and fixed inside it. At the same time, the first sound-absorbing cotton board, the gel board and the second sound-absorbing cotton board can be used to buffer, absorb and isolate the audio, thereby increasing the overall sound insulation effect and avoiding noise pollution to people. However, in actual use, the partition board is complicated to disassemble and install, cannot be used independently, has poor sound insulation effect, cannot effectively isolate sound, and has poor protection and is easily ignited, with a high risk of fire.

[0038] In the present invention, the wall panel frame 4 made of high-strength alloy steel is corrosion-resistant and rigid, which can prevent damage to the edges of the partition boards during transportation and movement, thereby affecting the appearance. At the same time, the wall panel frame 4 adopts a hollow structure inside to reduce the overall weight, facilitate transportation, and reduce material production costs.

[0039] Furthermore, four tenons 40 are symmetrically provided on the left side of the wall panel frame 4 near each corner, and four mortises 41 are symmetrically provided on the right side of the wall panel frame 4 corresponding to the tenons 40. A drill hole 400 is provided at the center of the tenon 40, and a threaded hole 410 is provided at the center of the mortise 41. The threaded hole 410 is equipped with a fixing screw 43, which passes through the drill hole 400 and is threadedly connected to the mortise 41.

[0040] In the present invention, the fixing screw 43 cooperates with the drill hole 400 and the threaded hole 410 to facilitate and quickly fix and separate the tenon 40 and the mortise 41.

[0041] Specifically, the mortise 41 is plugged into the tenon 40 , and the outer surface of the tenon 40 is tightly fitted with the inner wall of the mortise 41 .

[0042] In the present invention, the mortise 41 and the tenon 40 are plugged into each other to achieve quick fixation of the wall panel frames 4 .

[0043] It should be noted that a sound insulation layer 1 is provided at the center of the wall panel frame 4, and a number of sound insulation cabins 10 are opened inside the sound insulation layer 1. The sound insulation cabins 10 are distributed at equal intervals, and the sound insulation cabins 10 are filled with sound insulation sponges 100. The outer wall of the sound insulation sponge 100 is tightly fitted with the inner wall of the sound insulation cabin 10.

[0044] In the present invention, the sound insulation layer 1 is made of rock wool board, which is an inorganic fiber board made of basalt as the main raw material and processed by high-temperature melting. The sound insulation layer 1 has the characteristics of light weight, low thermal conductivity, heat absorption and non-flammability. At the same time, the sound insulation effect of the sound insulation layer 1 is increased by filling the sound insulation sponge 100 in the evenly distributed sound insulation cabin 10.

[0045] Secondly, a sound absorbing layer 2 is provided on the front and rear sides of the sound insulation layer 1, and a plurality of sound absorbing cabins 20 are opened inside the sound absorbing layer 2. Preferably, the outer walls on both sides of the sound insulation layer 1 are bonded and fixed to the outer wall on one side of the sound absorbing layer 2, and the sound absorbing cabin 20 generally presents a honeycomb structure.

[0046] In the present invention, the sound-absorbing layer 2 is made of mineral wool, which makes the sound-absorbing layer 2 have the characteristics of light weight, durability, non-flammability, no rot, no mildew, no insect damage, and sound absorption. At the same time, the sound-absorbing cabin 20 has a honeycomb structure and has geometric stability. The honeycomb structure can provide higher compressive strength and rigidity.

Then, a sound insulation chamber 10 is opened in the sound insulation layer 1, and the sound insulation chamber 10 is filled with a sound insulation sponge 100 to seal the sound insulation layer 1. Sound-absorbing compartments 20 are formed in the sound-absorbing layer 2, and perforations 200 are formed between the sound-absorbing compartments 20 to allow air to circulate in each sound-absorbing compartment 20, thereby satisfying the small-hole sound absorption condition. One side of each of the two sound-absorbing layers 2 is bonded to the front and rear sides of the sound insulation layer 1. The sound insulation layer 1 and the sound-absorbing layer 2 are placed into the wallboard frame 4 through the hole above the wallboard frame 4. The positions of the sound insulation layer 1 and the sound-absorbing layer 2 are adjusted so that the sound insulation layer 1, the sound-absorbing layer 2 and the wallboard frame 4 are parallel to each other. The protective layer 3 is bonded to the other side of the sound-absorbing layer 2.
