DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0022] Please refer to Figs. 1 to 4 In the embodiment, the sound-absorbing partition wall plate based on autoclaved lightweight aerated concrete includes a support structure installed on one side of the inner wall of the wall 1 and a wall plate structure connected to the support structure, wherein a 2cm space is reserved between the support structure and the wall 1, so that the wall plate structure can avoid mutual contact and conduction with the wall 1.

[0023] In the embodiment, the support structure includes a plywood 4 fixed on one side of the wall 1, and a keel 6 fixedly installed on the surface of the plywood 4. The size of the plywood 4 corresponds to the size of the single-sided wall in the room, and the outer periphery of the plywood 4 is surrounded by sound insulation cotton 3 to improve the contact tightness of the outer part of the plywood 4.

[0024] Preferably, the inner wall surface of the wall 1 is also bonded with a rubber strip 2, and the rubber strip 2 surrounds a rectangular frame shape, and the plywood 4 and the sound insulation cotton 3 are located in the rectangular space surrounded by the rubber strip 2.

[0025] In the present application, the rubber strip 2 is surrounded on the inner wall of the wall 1, and the plywood 4 and the sound insulation cotton 3 are installed to close the wall 1, so that a cavity can be left between the wall surface of the wall 1 and the plywood 4 to reduce noise transmission, and the keel 6 on the surface of the plywood 4 can provide connection of the wall plate structure.

[0026] It should be noted that the keel 6 is continuously distributed on the plywood 4, and the surface of the keel 6 is fixedly installed with a keel frame 7 for connection, and the front surface of the keel frame 7 is fixedly installed with a U-shaped frame 8 extending to the outside of the rubber strip 2, so that the U-shaped frame 8 can be connected relative to the wall plate structure.

[0027] In the embodiment, the wall plate structure includes a sound insulation board 5 for sound absorption and blocking, a mounting plate 9 fixedly installed on one side of the sound insulation board 5, and a secondary keel 11 fixedly installed on the mounting plate 9, and the U-shaped frame 8 corresponds to the secondary keel 11. By placing the secondary keel 11 in the U-shaped frame 8, the sound insulation board 5 can be supported and pre-fixed on the keel frame 7.

[0028] In the embodiment, the U-shaped frame 8 is penetrated by bolts 10 for fixing the secondary keel 11, and the secondary keel 11 is penetrated by bolt holes 12 for the bolts 10 to pass through. By using the bolts 10 to pass through the secondary keel 11, the sound insulation board 5 can be supported and installed.

[0029] It should be noted that the sound insulation board 5 includes a sound insulation layer 51, a surface layer 52, and a back plate layer 53. Specifically, the sound insulation layer 51 is solidified into a plate shape by autoclaved lightweight aerated concrete, and is the most important part of the sound insulation board 5, which is used to absorb and reduce the propagation and reflection of sound. The surface layer 52 is a layer of external covering material, such as wood, gypsum board, metal plate, etc., which is used to protect the internal sound insulation material and can also play a decorative role. The back plate layer 53 is made of steel plate, which is used to enhance the structural strength and stability of the sound insulation board 5.

[0030] Based on the sound insulation board 5 of the sound insulation layer 51, the autoclaved aerated treatment is performed to form a large number of tiny pores inside, thereby reducing the density of the material and ensuring that the sound absorption effect is higher than that of traditional rock wool and glass wool materials, and the lightweight is easy to load.

[0031] The working principle of the above embodiment is as follows:

[0032] The rubber strip 2 is pasted in a rectangular shape at an interval of 2 cm from the wall surface on the side of the wall 1 where the sound absorption partition wall is to be installed, and the sound insulation cotton 3 and the plywood 4 are continuously installed on the inner side of the rubber strip 2. The plywood 4 is fixed, and after the plywood 4 is stably set, the keel frame 7 is added to the front side of the keel 6 connected to the plywood 4. The sound insulation board 5 made of the sound insulation layer 51 is connected to the U-shaped frame 8 corresponding to the front side of the keel frame 7 on the side of the secondary keel 11. The secondary keel 11 is fixed relative to the U-shaped frame 8 by using the bolts 10. The sound absorption partition wall is set, and the sound insulation performance is improved by the large number of tiny pores formed inside the autoclaved lightweight aerated concrete material, and the durability is good.
