Description

Technical Field

[0001] This utility model relates to the field of ALC board sound insulation technology, and in particular to a composite sound insulation ALC board. Background Technology

[0002] ALC panels, or Autoclaved Lightweight Concrete panels, are widely used in the construction industry due to their numerous advantages, including lightweight, high strength, thermal insulation, fire resistance, and environmental friendliness. They are particularly prevalent in partition walls and exterior walls, becoming one of the mainstream wall materials in modern prefabricated buildings. However, in practical applications, the sound insulation performance of traditional ALC panels has consistently faced a significant bottleneck: When installing traditional ALC panels, the joints between the panels are usually sealed with ordinary cement mortar. However, cement mortar is prone to shrinkage and cracking during the setting process, and it's difficult to ensure the joints are completely filled manually, easily creating tiny gaps wider than 0.5mm. These gaps become channels for sound wave propagation. Even if the ALC panels themselves meet sound insulation standards, noise can still penetrate the wall through the gaps, significantly reducing the overall sound insulation effect.

[0003] Therefore, it is necessary to provide a new composite sound insulation ALC board to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a composite sound insulation ALC board.

[0005] The composite sound insulation ALC panel provided by this utility model includes: an ALC panel body, sound insulation cotton, a flame retardant board, and a sealing strip. A gypsum coating is provided on one side of the ALC panel body. Sound insulation cotton for absorbing noise is installed inside the ALC panel body. A flame retardant board is installed inside the ALC panel body, located between the sound insulation cotton and the gypsum coating. A sealing strip is provided on one side of the ALC panel body.

[0006] Preferably, the ALC panel body has a first mounting groove inside, and the sound insulation cotton is placed inside the first mounting groove. The ALC panel body also has a second mounting groove inside, and the flame retardant board is placed inside the second mounting groove.

[0007] Preferably, pin holes are provided inside both ends of the second mounting groove, and pins for fixing the flame-retardant plate are inserted into the pin holes.

[0008] Preferably, the gypsum coating is placed inside the second mounting groove, with one side in contact with the flame-retardant plate and the other side flush with the side wall of the ALC plate body.

[0009] Preferably, a groove is provided on the side of the ALC plate body near the sealing strip, and the sealing strip is fixedly connected to the inner wall of the groove. A protrusion matching the groove is fixedly connected to the other side of the ALC plate body, and a mating groove matching the sealing strip is provided inside the protrusion. In the installed state, the protrusion is placed inside the groove and fits against its inner wall, and the sealing strip is placed inside the mating groove and fits against its inner wall.

[0010] Preferably, the sound insulation cotton is made of 5mm thick foam material.

[0011] Compared with related technologies, the composite sound insulation ALC board provided by this utility model has the following beneficial effects: Through the design of sound insulation cotton and flame retardant board, when sound waves enter, they can be reflected and absorbed multiple times inside. After the sound waves enter the tiny pores of the sound insulation cotton, they continuously collide with the inner wall of the pores, and the sound energy is gradually converted into heat energy and consumed, thereby effectively weakening the sound energy and reducing the intensity of sound propagation. This internal sound insulation design effectively blocks the sound from the path of sound source propagation, greatly reducing the sound wave energy entering the board. The gypsum coating acts as a sealing layer, further sealing the second mounting groove and reducing the possibility of sound propagating through the gaps in the mounting groove. At the same time, it enhances the overall sealing and structural integrity of the ALC board, creating a relatively independent and enclosed soundproof space inside the board, effectively preventing sound from spreading and leaking within the board. The design of the sealing strip and the mating groove effectively fills the tiny gaps between the protrusions and grooves. Compared with the traditional method of filling and sealing the joints of ALC panels with cement mortar, which is prone to shrinkage and cracking during the solidification process and is difficult to ensure the density of the filling during manual operation, making it easy to form tiny gaps that become channels for sound wave propagation, the sealing strip overcomes this defect. It can always maintain a tight fit with the protrusions and the mating groove, preventing sound waves from propagating through the panel joints and greatly improving the sound insulation performance at the panel joints.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] Please see Figures 1 to 4 A composite sound insulation ALC board includes: an ALC board body 1, sound insulation cotton 3, a flame retardant board 4, and a sealing strip 5. A gypsum coating 2 is provided on one side of the ALC board body 1. Sound insulation cotton 3 for absorbing noise is installed inside the ALC board body 1. A flame retardant board 4 is installed inside the ALC board body 1, located between the sound insulation cotton 3 and the gypsum coating 2. A sealing strip 5 is provided on one side of the ALC board body 1.

[0017] The ALC panel body 1 has a first mounting groove 6 inside, and the sound insulation cotton 3 is placed inside the first mounting groove 6. The ALC panel body 1 has a second mounting groove 7 inside, and the flame retardant board 4 is placed inside the second mounting groove 7.

[0018] The second mounting groove 7 has pin holes 8 at both ends, and pins 9 for fixing the flame-retardant plate 4 are inserted into the pin holes 8.

[0019] The gypsum coating 2 is placed inside the second mounting groove 7, with one side in contact with the flame-retardant plate 4 and the other side flush with the side wall of the ALC plate body 1.

[0020] A groove 11 is provided on one side of the ALC board body 1 near the sealing strip 5. The sealing strip 5 is fixedly connected to the inner wall of the groove 11. A protrusion 10 matching the groove 11 is fixedly connected to the other side of the ALC board body 1. The protrusion 10 has a mating groove 12 matching the sealing strip 5 inside. In the installed state, the protrusion 10 is placed inside the groove 11 and fits against its inner wall. The sealing strip 5 is placed inside the mating groove 12 and fits against its inner wall.

[0021] The sound insulation cotton 3 is made of 5mm thick foam material.

[0022] It should be noted that the design of the protrusion 10 and the groove 11 provides precise positioning for the splicing of the ALC board, ensuring that the two boards can be accurately aligned during splicing, laying the foundation for a good sealing effect. As the protrusion 10 is fully embedded in the groove 11, the sealing strip 5 fixed on the inner wall of the groove 11 smoothly embeds into the mating groove 12 opened on the outer wall of the protrusion 10, and tightly fits the inner wall of the mating groove 12. The sealing strip 5 has good elasticity and sealing performance, which can effectively fill the tiny gap between the protrusion 10 and the groove 11, preventing sound waves from propagating through the board seam.

[0023] The working principle of the composite sound insulation ALC board provided by this utility model is as follows: During the production of ALC panels, a first mounting groove 6 is made inside the ALC panel body, and a 5mm thick foam sound insulation cotton 3 is placed inside the first mounting groove 6. Due to its porous structure, the sound insulation cotton 3 can reflect and absorb sound waves multiple times inside, effectively weakening sound energy and thus absorbing noise and reducing the intensity of sound propagation. A second mounting groove 7 is made inside the ALC panel body, and a flame-retardant board 4 is placed inside, ensuring that the flame-retardant board 4 completely covers the sound insulation cotton 3. The presence of the flame-retardant board 4 not only provides a certain degree of protection for the sound insulation cotton 3, but more importantly, it itself possesses flame-retardant properties. Pin holes 8 are made inside both ends of the second mounting groove 7. Pins 9 are accurately inserted into the corresponding pin holes 8 to securely fix the flame retardant board 4. This fixing method ensures that the flame retardant board 4 will not shift during use, always maintains effective coverage of the sound insulation cotton 3, ensures the stability of the overall structure of the composite sound insulation ALC board, and thus ensures the continuous and effective performance of its sound insulation and flame retardant functions. Next, the gypsum coating 2 is evenly applied to the flame-retardant board 4 inside the second mounting groove 7 until the entire second mounting groove 7 is filled, and the gypsum coating 2 is flush with the side wall of the ALC board. The gypsum coating 2 serves two purposes: firstly, it beautifies the appearance of the ALC board, making its surface smooth and flat; secondly, it acts as a sealing layer, further sealing the second mounting groove 7, reducing the possibility of sound transmission through the gaps in the mounting groove, and enhancing the overall sealing and structural integrity of the ALC board. After the gypsum coating 2 has solidified, the ALC board can proceed to the subsequent installation stage. During installation, the protrusion 10 on one side of an ALC panel is aligned with the groove 11 on the other side of an adjacent ALC panel. The design of the protrusion 10 and groove 11 provides precise positioning for the splicing of the ALC panels, ensuring accurate alignment of the two panels during splicing and laying the foundation for a good sealing effect. As the protrusion 10 is fully embedded in the groove 11, the sealing strip 5 fixed to the inner wall of the groove 11 smoothly embeds into the mating groove 12 on the outer wall of the protrusion 10 and tightly fits the inner wall of the mating groove 12. The sealing strip 5 has good elasticity and sealing properties, effectively filling the tiny gap between the protrusion 10 and the groove 11, preventing sound waves from propagating through the panel seam. Traditional ALC panel seams are filled and sealed with ordinary cement mortar, which is prone to cracking due to cement mortar shrinkage and incomplete filling, resulting in gaps and a decrease in sound insulation effect. However, this composite sound insulation ALC panel overcomes this defect through the design of the sealing strip 5, greatly improving the sound insulation performance at the panel seam. Following the above steps, the remaining ALC panels are then installed sequentially. The panels are installed and spliced ​​to form a complete wall structure. This standardized installation method ensures the consistency of sealing and sound insulation performance between all parts of the wall, thereby creating a building wall system with high-efficiency sound insulation, effectively blocking the intrusion of external noise and creating a quiet and comfortable indoor environment.
