Description

Technical Field

[0001] This application relates to the field of building assembly technology, and in particular to an autoclaved aerated concrete panel covered with an insulation layer. Background Technology

[0002] With the increasing emphasis on building energy efficiency standards, the application and technological development of wall insulation materials have received growing attention. Traditional building wall designs typically employ a six-sided cladding method, separating solid building materials from insulation materials. This design provides necessary mechanical strength and resistance to external forces while improving the wall's insulation performance, thus achieving energy conservation and emission reduction. However, in practical applications, the difference in thermal conductivity between different materials leads to the cold bridging effect. The cold bridging effect refers to heat loss in certain areas of the wall due to uneven heat conduction between the more thermally conductive solid material and the less thermally conductive insulation material, severely impacting the overall insulation performance.

An external insulation board is inserted into the settling tank to block heat conduction, thus mitigating the cold bridging effect to some extent. However, this solution suffers from the problem of a closed cavity structure. The manufacturing process limits the selection of the internal insulation board to filling, potentially influencing the choice of insulation materials and increasing the manufacturing and application costs of the wall panels.

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this application. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this application.

[0020] The embodiments described in this application are only some, not all, of the embodiments described herein. All other embodiments obtained by those skilled in the art based on the embodiments described herein without inventive effort are within the scope of protection of this application. In the description of this application, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] With the increasing emphasis on building energy efficiency standards, the application and technological development of wall insulation materials have received growing attention. Traditional building wall designs typically employ a six-sided cladding method, separating the solid building material from the insulation material. This design provides necessary mechanical strength and resistance to external forces while improving the wall's insulation performance, thus achieving energy conservation and emission reduction. However, in practical applications, the difference in thermal conductivity between different materials leads to the cold bridging effect. The cold bridging effect refers to heat loss in certain areas of the wall due to uneven heat conduction between the more thermally conductive solid material and the less thermally conductive insulation material, severely impacting the overall insulation performance.

[0022] To address this issue, patent document CN 119641018 A proposes a technical solution that involves creating a cavity within the base plate and installing an internal insulation board within the cavity. An external insulation board is inserted into the recess to block heat conduction, thus mitigating the cold bridging effect to some extent. However, this solution suffers from a closed cavity structure, making the insertion and replacement of the internal insulation board inconvenient and potentially affecting the durability and flexibility of the insulation effect.

[0023] To address the aforementioned technical problems, this application proposes an autoclaved aerated concrete (AAC) panel with a thermal insulation layer. Please refer to [link / reference needed]. Figures 1 to 6 In one embodiment of this application, the autoclaved aerated concrete (AAC) panel with insulation layer includes a base plate 100, a settling trough 300, and an external insulation panel 400. The settling trough 300 is formed on the outer periphery of the base plate 100, and the opening of the settling trough 300 extends outward away from the base plate 100 so that the external insulation panel 400 can be inserted into the settling trough 300 along the opening. The AAC panel with insulation layer also includes an internal insulation panel 200, a receiving cavity 130, and a receiving opening 150. The receiving cavity 130 is disposed within the base plate 100 and extends from the inside of the base plate 100 to the outside of the base plate 100 to form the receiving opening 150 so that the internal insulation panel 200 can be inserted into the receiving cavity 130 along the receiving opening 150.

[0024] The technical solution of this application adopts a receiving cavity 130 in the base plate 100, which extends from the inside of the base plate 100 to the outside of the base plate 100 and forms a receiving opening 150. This allows for the convenient insertion and replacement of the internal insulation board 200, thereby effectively improving the overall thermal insulation performance of the building, which is conducive to reducing energy consumption and improving living comfort.

[0025] Please see Figure 1 and Figure 2 In one embodiment, the base plate 100 includes an integrally formed shell 140, a first plate 110, and a second plate 120. A recess 300 is formed on the outer periphery of the shell 140. The shell 140, the first plate 110, and the second plate 120 enclose a receiving cavity 130. The receiving cavity 130 extends from the first plate 110 toward the second plate 120 and penetrates the second plate 120 to form a receiving opening 150. An internal insulation plate 200 is inserted into the receiving cavity 130. Specifically, the shape of the recess 300 can be rectangular, L-shaped, or U-shaped. This embodiment, by integrally forming the shell 140, the first plate 110, and the second plate 120, can improve the stability and integrity of the structure, which is beneficial to reducing errors and installation time during assembly. At the same time, the recess 300 design helps to improve sealing, ensuring effective fixation of the internal insulation plate 200 and internal temperature control.

[0026] Please see Figure 1 and Figure 5 In one embodiment, the autoclaved aerated concrete (AAC) panel covered with the insulation layer further includes a sealing structure 700. The sealing structure 700 is disposed at the receiving opening 150, and the side of the sealing structure 700 facing away from the inner insulation panel 200 is flush with the second page 120. The sealing structure 700 is used to seal the receiving opening 150 after the inner insulation panel 200 is inserted. This embodiment, by providing the sealing structure 700 at the receiving opening 150, effectively seals the receiving opening 150 after the inner insulation panel 200 is inserted, enhancing the sealing and stability of the structure, improving the insulation effect, preventing the entry of external substances, and ensuring the long-term stable operation of the system.

[0027] Please see Figure 1 In one embodiment, the autoclaved aerated concrete (AAC) panel covered with the insulation layer also includes a filler material that fills the gap between the inner insulation panel 200 and the inner wall of the receiving cavity 130. This embodiment, by filling the gap between the inner insulation panel 200 and the inner wall of the receiving cavity 130 with a filler material, can further enhance insulation performance, reduce heat conduction and airflow, and improve the overall insulation effect and structural airtightness. Furthermore, the use of the filler material helps to fill any possible gaps, ensuring the stability and long-term durability of the structure.

[0028] Please see Figure 1 and Figure 3 In one embodiment, the autoclaved aerated concrete (AAC) panel covered with an insulation layer further includes a reinforcing structure 500 disposed within the base plate 100. The settling groove 300 includes a first groove 310 and a second groove 320 that are interconnected. The first groove 310 is distributed around the periphery of the base plate 100, and the second groove 320 is distributed along the direction of the reinforcing structure 500. This embodiment, by providing the reinforcing structure 500 in the AAC panel, can improve the compressive strength and deformation resistance of the panel, which is beneficial to improving the stability and durability of the overall structure, ensuring reliability and safety during long-term use. Furthermore, by providing the settling groove 300, it is convenient to place the external insulation board 400 on the base plate 100.

[0029] Please see Figure 4 In one embodiment, a waterproof layer is provided on the outer side wall of the reinforcing structure 500. This embodiment, by providing a waterproof layer on the outer side wall of the reinforcing structure 500, can effectively prevent water intrusion, enhance the durability of the structure 500 in humid environments, improve the waterproof performance of the product, and extend its service life.

[0030] Please see Figure 1 In one embodiment, a waterproof layer is provided on the inner wall of the receiving cavity 130. This embodiment, by providing a waterproof layer on the inner wall of the receiving cavity 130, can effectively prevent moisture penetration, ensure that the insulation inside the receiving cavity 130 is not affected by moisture, and help improve the durability and performance stability of the equipment, extend its service life and reduce the frequency of maintenance.

[0031] Please see Figures 4 to 6 In one embodiment, the autoclaved aerated concrete (AAC) panel covering the insulation layer further includes a protective layer 600. The protective layer 600 is fixedly connected to the side of the outer insulation panel 400 facing away from the bottom of the settling tank 300, and the protective layer 600 is flush with the surface of the base panel 100. This embodiment, by providing a protective layer 600 on the AAC panel, effectively enhances the protective function of the outer insulation panel 400, prevents damage to the insulation layer from the external environment, improves the durability and compressive strength of the insulation panel, extends its service life, and reduces the impact of external impacts on the structure.

[0032] Please see Figure 4 and Figure 6In one embodiment, the autoclaved aerated concrete (AAC) panel covering the insulation layer also includes a wire mesh cage enclosed within the base plate 100, with the trough 300 not extending into the cage. This embodiment, by incorporating a wire mesh cage within the AAC panel, enhances the overall strength and stability of the structure, provides additional support, and ensures the durability of the insulation layer during use. The fact that the wire mesh cage is enclosed within the base plate 100 and the trough 300 does not extend into it avoids potential impacts of the trough 300 on the wire mesh cage structure, contributing to improved uniformity and stability of the protective layer 600, thereby enhancing the equipment's seismic and impact resistance.

[0033] Please see Figure 4 and Figure 5 In one embodiment, the depth of the settling tank 300 is h, where 15mm ≤ h ≤ 100mm. In this embodiment, the depth of the settling tank 300 is between 15mm and 100mm, ensuring that the tank 300 is not excessively deep while meeting the required strength and stability, thus avoiding unnecessary structural complexity or material waste. A reasonable depth helps ensure effective integration between the tank and the external insulation board 400, improving the overall structural robustness and protective effect, while controlling production costs and construction difficulty.

[0034] Please see Figure 4 and Figure 5 In one embodiment, the width of the recess 300 is L, 50mm ≤ L ≤ 100mm. In this embodiment, the width of the recess 300 is between 50mm and 100mm, which ensures sufficient accommodating space while avoiding excessive width that could lead to material waste or structural weakening. A reasonable width improves the bonding effect between the recess 300 and the external insulation board 400, ensuring stable installation of the external insulation board 400 while maintaining the overall structural strength and durability of the board.

[0035] Furthermore, the autoclaved aerated concrete (AAC) panels with insulation layers provided in this application can be processed using various methods. In one embodiment, please refer to... Figure 7 The autoclaved aerated concrete (AAC) panels covered with an insulation layer are processed using the following method, which specifically includes the following steps: S10. An internal insulation board is installed inside the cavity, and an external insulation board is fabricated.

[0036] In this step, when processing the external insulation panels, the panels are cut, drilled, or otherwise treated according to design requirements to ensure that their size and shape meet construction needs, facilitating subsequent installation and fixing. Precise processing ensures the accuracy and stability of the external insulation panel installation, providing a stable foundation for subsequent steps, avoiding incompatibility issues, and improving construction efficiency and quality.

[0037] S20. A groove is cut along the surface of the base plate.

[0038] In this step, grooves are cut along the surface of the baseboard. The depth and width of the grooves are precisely set according to design specifications to ensure they accommodate the dimensions and fixing requirements of the external insulation board. By creating grooves, the external insulation board can better bond with the baseboard, improving structural stability, enhancing the fixing effect of the protective layer, and thus improving insulation performance and overall seismic resistance.

[0039] S30. Clean the settling tank and apply interface agent and bonding mortar to the inner wall of the settling tank.

[0040] In this step, the settling tank is cleaned and an interface agent and bonding mortar are applied to the inner wall of the tank to ensure that the surface of the settling tank is clean and flat, laying a good foundation for subsequent bonding. The application of interface agent and bonding mortar can effectively enhance the adhesion between the insulation board and the base board, prevent detachment and hollowing, improve the stability and durability of the structure, and enhance the overall performance of the insulation system.

[0041] S40. After applying an interface agent to the external insulation board, fix it in the settling tank.

[0042] In this step, an interface agent is applied to the joint surfaces of the external insulation panels, and anchor bolts are used to fix the external insulation panels in the settling tank. Each external insulation panel has at least two anchor bolts. This step, after applying the interface agent and fixing the external insulation panels in the settling tank, ensures that the interface agent fully penetrates between the insulation panel and the base panel, improving the bonding strength. By applying the interface agent and using anchor bolts to fix the external insulation panels in the settling tank, with at least two anchor bolts for each external insulation panel, a secure fixation is ensured, preventing the insulation panels from falling off or deforming due to external forces, thus improving the stability and safety of the insulation layer.

[0043] S50. Securely connect the protective layer to the external insulation board layer by layer.

[0044] In this step, the protective layer is fixedly connected to the external insulation board using an adhesive-anchor combination, ensuring the protective layer is flush with the surface of the base board. This method ensures the stability and protective effect of the protective layer. The adhesive-anchor fixing method firmly bonds the protective layer to the external insulation board, preventing it from loosening or falling off due to external impacts during long-term use, thereby enhancing the durability of the overall structure and providing effective protection.

[0045] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this application and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this application should be included within the protection scope of this application.
