Technical Field

[0001] This utility model relates to the field of aerated concrete block technology, and in particular to a regenerative porous sound-absorbing and heat-insulating aerated concrete block. Background Technology

[0002] Aerated concrete blocks are lightweight building materials made primarily of siliceous and calcareous materials. They form a uniform porous structure through an aluminum powder gasification reaction and are then cured by high-temperature and high-pressure steam curing.

[0003] Existing aerated concrete block formulations have low waste utilization rates and are typically integrally molded. They form a porous structure through the gasification reaction of aluminum powder, and are then cut, steam-cured under high temperature and pressure to finally form a uniform lightweight brick. The overall heat insulation and sound absorption are mainly achieved through the formation of a porous structure, resulting in low sound absorption and heat insulation effects. Additionally, the integral molding process leads to low strength.

[0004] Therefore, in view of the problems of low sound absorption and heat insulation effect and low strength of existing aerated concrete blocks, this utility model can generate a recycled block matrix by using waste materials and aluminum powder, thereby improving the utilization rate of waste materials. At the same time, the strength is improved by combining multiple layers, and the overall heat insulation and sound absorption effect can be improved by taking into account the structural characteristics of the heat insulation layer, functional layer and sound guiding layer.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a regenerated porous sound-absorbing and heat-insulating aerated concrete block, including a regenerated plate substrate 1; a positioning square groove 2 is provided at the center of the end face of the regenerated plate substrate 1, and a heat insulation layer 3 is installed on the outer side of the regenerated plate substrate 1, a functional layer 4 is installed on the outer side of the heat insulation layer 3, a sound guiding layer 5 is installed on the outer side of the functional layer 4, a protective layer 6 is installed on the outer side of the sound guiding layer 5, a combined square groove 7 is provided on the inner wall of the end of the protective layer 6, a sealing layer 8 is installed inside the end of the protective layer 6, and the inner surface of the sealing layer 8 is bonded and fixed to the end face of the regenerated plate substrate 1, the heat insulation layer 3, the functional layer 4 and the sound guiding layer 5.

[0024] The sealing layer 8 is symmetrically distributed on the protective layer 6, and the outer surface of the sealing layer 8 is flush with the end face of the protective layer 6. The sealing layer 8 is connected to the combined square groove 7 by a snap-fit ​​connection. The depth of the combined square groove 7 is equal to the rear end of the sealing layer 8, and the length and width of the combined square groove 7 are greater than the length and width of the sound guiding layer 5. This facilitates the precise combination of the sealing layer 8 and the protective layer 6, keeping the outer side flat while sealing the inside.

[0025] The sealing layer 8 includes a positioning block 81 and a limiting block 82. The positioning block 81 and the limiting block 82 are provided on the inner surface of the sealing layer 8, and the limiting block 82 is located at the center of the sealing layer 8. The positioning block 81 and the limiting block 82 are integrated with the sealing layer 8. The positioning block 81 is symmetrically distributed on the sealing layer 8, and the limiting block 82 is connected to the positioning groove 2 by an embedded engagement. The sealing layer 8 can maintain the stability of the assembly by the docking of the limiting block 82 and the positioning groove 2, avoid displacement and misalignment, and improve the accuracy of the docking of the positioning block 81.

[0026] The heat insulation layer 3 includes heat insulation and sound absorption holes 31 and heat layer grooves 32. The heat insulation and sound absorption holes 31 are evenly distributed on the edge of the heat insulation layer 3, and the outer diameter of the heat insulation and sound absorption holes 31 is larger than the inner diameter of the heat insulation and sound absorption holes 31. The heat insulation layer 3 is connected to the recycled plate substrate 1 by adhesive fixation. The heat layer grooves 32 are symmetrically opened at the ends of the heat insulation layer 3, and the heat layer grooves 32 are connected to the positioning block 81 by embedded engagement. According to the structure of the heat insulation and sound absorption holes 31 provided on the heat insulation layer 3, the heat insulation efficiency is improved. At the same time, the heat insulation and sound absorption holes 31 can further increase the sound absorption effect. Meanwhile, the heat insulation layer 3 improves the stability of the assembly through the positioning block 81.

[0027] The functional layer 4 is connected to the heat insulation layer 3 and the sound guiding layer 5 by adhesive bonding. The end of the functional layer 4 is symmetrically provided with positioning grooves 41, and the frame of the functional layer 4 is set with a honeycomb structure. The positioning grooves 41 and the positioning blocks 81 are connected by embedded engagement. The honeycomb structure of the functional layer 4 is conducive to increasing the overall heat insulation and sound absorption effect. At the same time, the functional layer 4 improves the stability of the assembly through the positioning blocks 81.

[0028] The sound guiding layer 5 includes sound transmission straight holes 51 and sound layer grooves 52. The sound transmission straight holes 51 are evenly distributed on the edge of the sound guiding layer 5, and the sound layer grooves 52 are symmetrically opened at the ends of the sound guiding layer 5.

[0029] Working principle: According to Figures 1-4First, the outer side of the recycled plate substrate 1 is sequentially covered with a heat insulation layer 3, a functional layer 4, a sound guiding layer 5, and a protective layer 6, and these layers are then bonded and fixed together. Next, the sealing layer 8 is embedded and fixed into the combination groove 7 on the protective layer 6. The sealing layer 8 can drive the limiting block 82 to be embedded and fixed into the positioning groove 2 on the recycled plate substrate 1, maintaining stability during the assembly process. This allows the sealing layer 8 to drive the positioning block 81 to be embedded and fixed into the heat layer groove 32, the positioning groove 41, and the sound layer groove 52, maintaining the firmness and strength of the assembly. At the same time, the sealing layer 8 is bonded and fixed to the recycled plate substrate 1, the heat insulation layer 3, the functional layer 4, and the sound guiding layer 5, completing the overall assembly.

[0030] according to Figure 5 During use, external gas and sound enter the interior through the protective layer 6. The sound and gas can quickly enter the functional layer 4 through the sound transmission holes 51. According to the honeycomb structure of the functional layer 4, sound can be absorbed. At the same time, the air in the honeycomb structure is divided into small units. Air itself is a poor conductor of heat, which reduces heat conduction. Meanwhile, the heat insulation and sound absorption hole 31 structure set on the heat insulation layer 3 further improves the heat insulation effect and can also perform sound absorption.
