Concrete blocks have the advantages of high strength, light self-weight, convenient masonry, good wall surface flatness, and high construction efficiency.

[0003] Existing ones, such as a lightweight sound insulation block and the wall built by it in the application number: 201920780398.3, include a lightweight sound insulation block, a mortar joint isolation strip, planar mortar, and vertical mortar. The mortar joint isolation strip is fixed on the track groove.

Therefore, we propose an aerated concrete block with improved sound insulation effect to solve the problems mentioned above. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem in the prior art that it only reflects noise and does not absorb and weaken the propagation of noise, but instead will affect the personnel on the other side of the building wall, and to propose an aerated concrete block with improved sound insulation effect.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: An aerated concrete block with improved sound insulation effect, including a block body. A sound absorption hole plate is fixedly connected to the center of the inner surface of the block body. Polyethylene foam layers are fixedly connected to the inner surface of the sound absorption hole plate near both side edges. Expanded polystyrene layers are fixedly connected to both sides of the inner surface of the sound absorption hole plate. Rubber layers are fixedly connected to both sides of the inner surface of the sound absorption hole plate. A polyurethane foam layer is fixedly connected to one side of the inner surface of the sound absorption hole plate. A sound insulation felt is fixedly connected to the center of the outer surface of the block body.

[0007] Preferably, a mineral wool layer is fixedly connected to the other side of the inner surface of the sound absorption hole plate.

[0008] Preferably, clamping plates are fixedly connected to the front and rear positions of the outer surface of one side of the sound insulation felt, and a first clamping groove is formed at the center of the inner surface of the clamping plate.

[0010] Preferably, a clamping block is fixedly connected to the center of the outer surface of the other side of the sound insulation felt.

[0011] Preferably, second clamping grooves are formed at the top and bottom of the outer surface of the clamping block.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] 1. In the present utility model, as shown in Figure 1 and Figure 2 , the polyethylene foam layer, the expanded polystyrene layer and the rubber layer are located on both sides of the sound absorption hole plate. Then, during actual use, through the mutual cooperation of the polyethylene foam layer, the expanded polystyrene layer and the rubber layer, the sound is gradually absorbed, thereby improving the sound insulation performance, ensuring that the external noise can reach an ideal blocking effect after being weakened by the three layers, so as to avoid affecting personnel. There are multiple round holes on the sound absorption hole plate, and the porous structure can generate scattering and attenuation of sound waves, and the air gaps can absorb the energy of sound waves, thereby reducing noise.

[0014] 2. In the present utility model, during use, through the cooperation of the polyurethane foam layer and the mineral wool layer, the sound wave absorption effect can be increased to play an auxiliary role. And through the sound insulation felt covering the building block, it has strong sound wave absorption ability, can effectively block and absorb sound, and thus can improve the sound insulation effect. If it is necessary to connect two building blocks, through the mutual cooperation of the first clamping groove, the second clamping groove, the clamping block and the clamping plate, the two building block bodies can be fully connected. And through the setting of the sealing ring, the sealing performance at the connection between the two can be improved, avoiding the appearance of gaps and preventing sound from being conducted through the gaps, so as to achieve a full sound insulation effect.

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other

[0021] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the limitations of the specific embodiments disclosed in the following specification

[0022] Example 1, as Figures 1-4 shown, an aerated concrete block for improving sound insulation effect includes a block body 1. A sound absorption perforated plate 8 is fixedly connected to the center of the inner surface of the block body 1. A polyethylene foam layer 5 is fixedly connected to the inner surface of the sound absorption perforated plate 8 near both side edges. Expanded polystyrene layers 6 are fixedly connected to both sides of the inner surface of the sound absorption perforated plate 8. Rubber layers 7 are fixedly connected to both sides of the inner surface of the sound absorption perforated plate 8. A polyurethane foam layer 10 is fixedly connected to one side of the inner surface of the sound absorption perforated plate 8. A sound insulation felt 4 is fixedly connected to the center of the outer surface of the block body 1

[0023] The effect achieved by the entire Example 1 is, as Figure 1 and Figure 2 shown, the sound absorption perforated plate 8 is arranged inside the block body 1. Then, through its setting, the porous structure on itself can cause the scattering and attenuation of sound waves, and the air voids can absorb the energy of sound waves, thereby reducing noise. The polyethylene foam layer 5, the expanded polystyrene layer 6 and the polyurethane foam layer 10 are arranged inside the sound absorption perforated plate 8 and at both sides. First, through the setting of the polyethylene foam layer 5, it can effectively absorb sound and has excellent acoustic performance. Through the setting of the expanded polystyrene layer 6, the sound insulation performance can be improved. Through the setting of the rubber layer 7, the effect of reducing noise can be achieved. Then, through the mutual cooperation of the above-mentioned components, the role of gradually absorbing sound can be achieved, ensuring that the external noise can reach an ideal blocking effect after being weakened by the above-mentioned components, so as to avoid the influence of noise on personnel

[0024] Example 2, as Figures 1-4As shown, a mineral wool layer 9 is fixedly connected to the other side position of the inner surface of the sound-absorbing perforated plate 8. Clamping plates 11 are fixedly connected to the front and rear positions of the outer surface of one side of the sound insulation felt 4. A first clamping groove 2 is formed at the center of the inner surface of the clamping plate 11. Sealing rings 3 are fixedly connected to the front and rear positions of the outer surface of the clamping plate 11. A clamping block 13 is fixedly connected to the center of the outer surface of the other side of the sound insulation felt 4. Second clamping grooves 12 are formed at the top and bottom of the outer surface of the clamping block 13.

[0025] The overall effect achieved by the entire Embodiment 2 is that the polyurethane foam layer 10 has good sound-absorbing performance and can effectively reduce low-frequency noise. Through the setting of the mineral wool layer 9, the overall sound insulation performance can be increased. Through the cooperation of the two, an auxiliary effect can be achieved, such as Figure 1 and Figure 2 As shown, the sound insulation felt 4 completely covers the surface of the building block body 1. Since the sound insulation felt 4 is usually made of a variety of composite materials and has strong sound wave absorption ability, the sound insulation effect of the building block body 1 is improved. Through the mutual cooperation of the first clamping groove 2, the clamping plate 11, the clamping block 13 and the second clamping groove 12, it is convenient for the user to connect two building block bodies 1 to each other. Through the setting of the sealing ring 3, the sealing performance at the connection of the two building block bodies 1 can be increased to avoid the existence of gaps.

[0026] Working principle: When in use, as Figure 2 shown, the sound insulation felt 4 completely covers the building block body 1. Through its setting, the noise can be initially absorbed. Then, through the multiple round holes on the sound-absorbing perforated plate 8, the scattering and attenuation of sound waves can occur, and the air gap can absorb the energy of the sound waves, thereby reducing the noise. And as Figure 1 and Figure 2 shown, the polyethylene foam layer 5, the expanded polystyrene layer 6 and the rubber layer 7 are located on both sides of the sound-absorbing perforated plate 8. Through the mutual cooperation of the polyethylene foam layer 5, the expanded polystyrene layer 6 and the rubber layer 7, the sound can be gradually absorbed. It can be ensured that after the noise is gradually weakened by the three, an ideal blocking effect can be achieved to avoid affecting the personnel. Through the mutual cooperation of the polyurethane foam layer 10 and the mineral wool layer 9, the overall sound insulation effect can be enhanced, thereby achieving an auxiliary effect. When it is necessary to connect two building block bodies 1, the user can align the clamping block 13 and the second clamping groove 12 on one building block body 1 with the first clamping groove 2 and the clamping plate 11 of one of the building block bodies 1. After alignment, the two building block bodies 1 can be moved closer to each other. When they are close to a certain position, the clamping block 13 will enter the first clamping groove 2, and the second clamping groove 12 will contact the outer surface of the clamping plate 11, thus completing the connection of the two building block bodies 1. Through the setting of the sealing ring 3, the sealing performance at the connection of the two building block bodies 1 can be increased to avoid the existence of gaps.

[0027] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
