Description

Technical Field

[0001] This application relates to the field of building assembly technology, and in particular to an autoclaved aerated concrete panel with a hollow built-in insulation board and its processing method. Background Technology

[0002] Autoclaved aerated concrete (AAC) panels, with their lightweight properties, minimal deformation, and excellent thermal insulation performance, are widely used in the domestic construction industry. As an important building material, they not only significantly reduce the overall weight of buildings but also substantially improve energy efficiency, contributing to energy conservation and emission reduction. However, with the construction industry's increasing demands for thermal insulation and energy conservation, traditional AAC panels have begun to reveal their shortcomings, especially in meeting higher insulation standards. Their single-material construction is no longer sufficient to meet increasingly stringent energy-saving requirements. To overcome this limitation, the industry has gradually begun to explore technologies that combine AAC panels with organic insulation materials, aiming to improve insulation performance while maintaining structural strength.

[0003] However, the production process of autoclaved aerated concrete (AAC) panels is quite complex, requiring prolonged high-temperature and high-pressure autoclaving to ensure the material's density and strength. High-temperature, high-pressure saturated steam melts most organic insulation materials, and all fibrous insulation materials (such as rock wool) become saturated with water and lose their insulation properties. In recent years, some research has attempted to inject foaming materials such as polyurethane into the internal cavities of AAC panels to form a composite insulation layer, satisfying both structural strength requirements and improving insulation performance. While this approach optimizes the overall performance of the product to some extent, polyurethane materials suffer from high cost and flammability, severely hindering their widespread application and promotion. Summary of the Invention

[0004] The purpose of this application is to provide a hollow autoclaved aerated concrete (AAC) panel with built-in insulation and its processing method, aiming to solve the technical problems of flammability and high cost of polyurethane materials in the existing AAC panel production process.

[0005] To achieve the above objectives, this application proposes a hollow autoclaved aerated concrete (AAC) panel with an internal insulation board, wherein the hollow autoclaved aerated concrete (AAC) panel with an internal insulation board comprises:

[0006] The base plate, the receiving cavity disposed in the base plate, and the reinforcing rib disposed in the receiving cavity, wherein the receiving cavity extends from the interior of the base plate to the exterior of the base plate and forms a receiving opening;

[0007] An insulation board is inserted into the receiving cavity through the receiving opening to enhance the thermal insulation performance of the autoclaved aerated concrete board.

[0008] In one embodiment, the base plate includes a first plate surface and a second plate surface, and the receiving cavity extends from the first plate surface in a direction perpendicular to the first plate surface and the second plate surface and penetrates the second plate surface to form the receiving opening.

[0009] In one embodiment, the autoclaved aerated concrete panel with hollow built-in insulation board further includes a sealing structure. The sealing structure is disposed at the receiving opening, and the side of the sealing structure opposite to the insulation board is flush with the second panel surface. The sealing structure is used to seal the receiving opening after the insulation board is inserted.

[0010] In one embodiment, the base plate further includes a third plate surface and a fourth plate surface, and the reinforcing rib includes an integrally formed first rib and a second rib, the first rib being connected to the third plate surface and the second rib being connected to the fourth plate surface.

[0012] In one embodiment, the first rib is integrally formed with the third plate surface, and the second rib is integrally formed with the fourth plate surface.

[0013] In one embodiment, the reinforcing rib divides the receiving cavity into a first cavity and a second cavity, and the insulation plate includes a first insulation part and a second insulation part, which are respectively inserted into the first cavity and the second cavity.

[0014] In one embodiment, the inner walls of both the first cavity and the second cavity are provided with a waterproof layer.

[0015] In one embodiment, the autoclaved aerated concrete slab with hollow built-in insulation board further includes a wire mesh cage, which is disposed inside the base plate and integrally formed with the base plate. The inner diameter of the wire mesh cage is larger than the outer diameter of the receiving cavity, so that the wire mesh cage wraps around the receiving cavity but does not extend into the receiving cavity.

[0016] In one embodiment, the autoclaved aerated concrete slab with hollow built-in insulation board further includes a filling material, which is filled into the gap between the insulation board and the inner wall of the receiving cavity.

[0017] In one embodiment, the insulation board is a vacuum insulation board, aerogel felt (board), rock wool board, glass wool board, ceramic wool board or other inorganic insulation board, extruded board, graphite extruded board, polyurethane foam board or other organic insulation board.

[0018] In one embodiment, the insulation board is an insulation board made of injected foam material.

[0019] Furthermore, to achieve the above objectives, this application also proposes a processing method for an autoclaved aerated concrete (AAC) panel with a hollow internal insulation board. This processing method is applied to the autoclaved aerated concrete (AAC) panel with a hollow internal insulation board as described above. The processing method includes:

[0020] Process the wire mesh cage and two hot-melt plates;

[0021] Two hot-melt plates are fixed to the positions of the first and second chambers of the wire mesh cage, respectively.

[0022] Place the wire mesh cage with the hot melt plate fixed in it into the slurry of the mold frame;

[0023] The mold frame is placed in the curing room for curing.

[0024] After the slurry in the mold frame reaches the preset strength, the concrete blank is obtained.

[0026] Steam is injected into the autoclave to melt the hot melt plate and simultaneously create cavities and ribs;

[0027] Clean the cavity and insert the insulation plate;

[0028] The filling material is filled into the gap between the insulation board and the inner wall of the cavity;

[0029] Seal off the intake opening.

[0030] The above-mentioned technical solution of this application has at least the following beneficial technical effects:

[0031] The technical solution of this application adopts a method of creating a receiving cavity in the base plate and inserting the insulation board into the receiving cavity, using the insulation board instead of polyurethane. This not only enhances the thermal insulation performance of the autoclaved aerated concrete (AAC) board, but also reduces production costs and improves the safety of the material, thereby promoting the wider application of AAC boards in the construction industry.

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.

[0040] 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," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] Autoclaved aerated concrete (AAC) panels, with their lightweight properties, minimal deformation, and excellent thermal insulation performance, are widely used in the domestic construction industry. As an important building material, they not only significantly reduce the overall weight of buildings but also substantially improve energy efficiency, contributing to energy conservation and emission reduction. However, with the construction industry's increasing demands for thermal insulation and energy conservation, traditional AAC panels have begun to reveal their shortcomings, especially in meeting higher insulation standards. Their single-material construction is no longer sufficient to meet increasingly stringent energy-saving requirements. To overcome this limitation, the industry has gradually begun to explore technologies that combine AAC panels with organic insulation materials, aiming to improve insulation performance while maintaining structural strength.

[0042] However, the production process of autoclaved aerated concrete (AAC) panels is quite complex, requiring prolonged high-temperature and high-pressure autoclaving to ensure the material's density and strength. High-temperature, high-pressure saturated steam melts most organic insulation materials, and all fibrous insulation materials (such as rock wool) become saturated with water and lose their insulation properties. In recent years, some research has attempted to inject foaming materials such as polyurethane into the internal cavities of AAC panels to form a composite insulation layer, satisfying both structural strength requirements and improving insulation performance. While this approach optimizes the overall performance of the product to some extent, polyurethane materials suffer from high cost and flammability, severely hindering their widespread application and promotion.

[0043] To address the aforementioned technical problems, this application proposes a hollow autoclaved aerated concrete (AAC) panel with an internal insulation board. Please refer to [link / reference needed]. Figure 1 and Figure 4 In one embodiment of this application, the hollow autoclaved aerated concrete (AAC) panel with an internal insulation board includes a base plate 100, a receiving cavity 200, reinforcing ribs 300, and an insulation board 500. The receiving cavity 200 is formed within the base plate 100, and the reinforcing ribs 300 are provided within the receiving cavity 200. The receiving cavity 200 extends from the interior of the base plate 100 to the exterior of the base plate 100, forming a receiving opening 400. The insulation board 500 is inserted into the receiving cavity 200 through the receiving opening 400 to enhance the thermal insulation performance of the AAC panel.

[0044] The technical solution of this application adopts a method of opening a receiving cavity 200 in the base plate 100 and inserting the insulation board 500 into the receiving cavity 200. The insulation board 500 is used to replace polyurethane, which can enhance the thermal insulation performance of autoclaved aerated concrete board, reduce production costs, and improve the safety of materials. This is conducive to promoting the wider application of autoclaved aerated concrete board in the construction industry.

[0045] Please see Figures 1 to 3In one embodiment, the base plate 100 includes a first plate surface 110 and a second plate surface 120. A receiving cavity 200 extends from the first plate surface 110 in a direction perpendicular to both the first and second plate surfaces 110 and penetrates the second plate surface 120 to form a receiving opening 400, facilitating the insertion of the insulation board 500 into the receiving cavity 200 through the receiving opening 400. This embodiment, by designing the first plate surface 110 and the second plate surface 120 in the base plate 100 and forming the receiving opening 400 through the second plate surface 120, allows for convenient insertion of the insulation board 500 into the receiving cavity 200, simplifying the installation process. Furthermore, it ensures that the insulation board 500 is securely embedded in the base plate 100, guaranteeing a tight bond between the insulation board 500 and the base plate 100, improving the insulation effect, and effectively avoiding the complex operations and time consumption of traditional installation methods, thus helping to improve construction efficiency and reduce labor costs.

[0046] Please see Figures 2 to 4 In one embodiment, the autoclaved aerated concrete (AAC) panel with a hollow internal insulation board further includes a sealing structure 600. The sealing structure 600 is disposed at the receiving opening 400, and the side of the sealing structure 600 facing away from the insulation board 500 is flush with the second panel surface 120. The sealing structure 600 is used to seal the receiving opening 400 after the insulation board 500 is inserted. This embodiment, by providing the sealing structure 600 at the receiving opening 400, can effectively seal the receiving opening 400 after the insulation board 500 is inserted, ensuring that the insulation board 500 is stably fixed inside the base plate 100, avoiding any impact on the insulation effect due to loosening or displacement of the insulation board 500. The design of the sealing structure 600 being flush with the second panel surface 120 not only improves the aesthetics of the overall structure but also increases the sealing performance of the base plate 100, thereby enhancing the durability and reliability of the AAC panel.

[0047] Please see Figure 1 and Figure 2 In one embodiment, the base plate 100 further includes a third plate surface 130 and a fourth plate surface 140. The reinforcing rib 300 includes an integrally formed first rib 310 and a second rib 320. The first rib 310 is connected to the third plate surface 130, and the second rib 320 is connected to the fourth plate surface 140. This embodiment effectively enhances the overall strength and stability of the base plate 100, not only improving the compressive and bending resistance of the autoclaved aerated concrete (AAC) panel, but also uniformly distributing stress to prevent deformation or cracking of the panel during use. This helps extend the service life of the AAC panel and improves its safety and reliability in practical applications.

[0048] Please see Figure 1 and Figure 2In one embodiment, the first rib 310 is interference-fitted with the third plate surface 130, and the second rib 320 is interference-fitted with the fourth plate surface 140. This embodiment helps to enhance the connection strength between the ribs and the plate surface, ensures a tight fit between the components, and enhances the stability and durability of the base plate 100 under stress conditions, thereby improving the reliability and safety of the autoclaved aerated concrete (AAC) slab in long-term use.

[0049] Please see Figure 1 and Figure 2 In one embodiment, the first rib 310 is integrally formed with the third plate surface 130, and the second rib 320 is integrally formed with the fourth plate surface 140. This embodiment, through the integral forming of the first rib 310 with the third plate surface 130 and the second rib 320 with the fourth plate surface 140, effectively enhances the overall integrity and stability of the structure, thereby improving the product's load-bearing capacity and deformation resistance, reducing weaknesses at joints, and enhancing durability and safety during use.

[0050] Please see Figure 2 and Figure 3 In one embodiment, the reinforcing rib 300 divides the receiving cavity 200 into a first cavity 210 and a second cavity 220. The insulation board 500 includes a first insulation portion 510 and a second insulation portion 520, which are respectively inserted into the first cavity 210 and the second cavity 220. This embodiment, by dividing the receiving cavity 200 into the first cavity 210 and the second cavity 220 through the reinforcing rib 300, can effectively improve the insulation effect, prevent heat loss, and thus enhance the overall thermal insulation performance and energy efficiency. The independent arrangement of the first insulation portion 510 and the second insulation portion 520 is beneficial for optimizing the use of materials, improving the thermal insulation effect, simplifying the installation process, reducing the complexity of production and construction, and improving production efficiency.

[0051] Please see Figure 2 In one embodiment, the inner walls of both the first cavity 210 and the second cavity 220 are provided with a waterproof layer. This embodiment, by providing a waterproof layer on the inner walls of the first cavity 210 and the second cavity 220, effectively prevents moisture penetration, thereby improving the product's moisture resistance, extending its service life, and ensuring the stability and reliability of the structure in humid environments.

[0052] Please see Figure 1 and Figure 2In one embodiment, the autoclaved aerated concrete (AAC) panel with a hollow internal insulation board further includes a wire mesh cage. The wire mesh cage is disposed within the base plate 100 and integrally formed with the base plate 100. The inner diameter of the wire mesh cage is larger than the outer diameter of the receiving cavity 200, so that the wire mesh cage wraps around the receiving cavity 200 but does not extend into the receiving cavity 200. This embodiment, through the structural design of the wire mesh cage being integrally formed with the base plate 100, can effectively enhance the strength and stability of the base plate 100. At the same time, by setting the inner diameter of the wire mesh cage to be larger than the outer diameter of the receiving cavity 200, interference of the wire mesh cage with the cavity interior is avoided, which is conducive to the function of the receiving cavity 200 and improves the compressive strength of the overall structure. In this way, the heat transfer performance of the insulation layer can be optimized, the durability and service life of the autoclaved aerated concrete panel can be improved, heat loss can be effectively reduced, and its application effect in buildings can be enhanced.

[0053] Please see Figure 2 and Figure 3 In one embodiment, the autoclaved aerated concrete (AAC) panel with a hollow built-in insulation board further includes a filling material, which is filled into the gap between the insulation board 500 and the inner wall of the receiving cavity 200. This embodiment, by filling the gap between the insulation board 500 and the inner wall of the receiving cavity 200 with a filling material, effectively fills the gap, reduces the heat conduction path, and thus further improves the insulation performance of the AAC panel and enhances the overall thermal insulation effect. The application of the filling material helps to enhance the structural stability and compressive strength of the panel, avoids the potential thermal bridging effect caused by the gaps, optimizes the energy-saving effect of the panel, and improves its efficiency and comfort in buildings.

[0054] In one embodiment, the insulation board 500 is a rock wool board, glass wool board, ceramic wool board, aerogel felt, melamine board, or other inorganic insulation board 500. This embodiment, by employing rock wool board, glass wool board, ceramic wool board, aerogel felt, melamine board, or other inorganic insulation board 500, can provide a variety of thermal insulation and fire resistance options according to different needs, improving the thermal insulation effect and fire resistance rating of the autoclaved aerated concrete board, while enhancing structural stability. This is beneficial for meeting the energy-saving, heat insulation, and safety requirements of different building environments, significantly improving the applicability and overall performance of the board.

[0055] Furthermore, to achieve the above objectives, this application also proposes a processing method for autoclaved aerated concrete (AAC) panels with hollow internal insulation boards. This processing method is applied to AAC panels with hollow internal insulation boards as described above. In one embodiment, please refer to... Figure 5 The processing method of autoclaved aerated concrete (AAC) panels with hollow internal insulation boards includes the following steps:

[0056] S10, processing wire mesh cage and two hot melt plates.

[0057] In this step, a wire mesh cage conforming to the design requirements is fabricated using reinforcing steel. Then, organic boards with a density greater than 8 kg / m³ and meeting the design thickness are cut using an electric furnace wire according to the cavity dimensions to create hot-melt plates; two hot-melt plates are made. Next, a hot-melt rod is used to melt the holes for the steel rod insertion holes, the anti-buoyancy pressure top plate holes, and the connection positions for the wire mesh cage. This step, by using reinforcing steel to fabricate a wire mesh cage conforming to the design requirements and using an electric furnace wire to cut organic boards of the required thickness into hot-melt plates, ensures an accurate match in size and shape between the wire mesh cage and the hot-melt plates, effectively guaranteeing the stability and strength of the structure. Simultaneously, the fabrication of the hot-melt plates provides the necessary foundation for the subsequent molding and melting processes.

[0058] S20. Fix the two hot melt plates to the positions of the first and second chambers of the wire mesh cage, respectively.

[0059] In this step, steel rods are inserted sequentially into the rod holes of the hot-melt plate, the anti-buoyancy pressure top plate holes, and the upper and lower connecting holes of the mesh cage to fix the hot-melt plate between the two reinforcing mesh pieces of the mesh cage. The size of the hot-melt plate is larger than the planar size of the reinforcing mesh pieces. The mesh cage is then fixed to the saddle frame, which is in turn fixed to the mold frame. The upper end of the hot-melt plate extends 20mm to 70mm beyond the mesh cage connecting piece. This step, using steel rods inserted sequentially into the rod holes of the hot-melt plate, the anti-buoyancy pressure top plate holes, and the upper and lower connecting holes of the mesh cage, ensures that the hot-melt plate is firmly connected between the two reinforcing mesh pieces of the mesh cage, thereby ensuring that the position of the mesh cage does not shift during subsequent molding processes, guaranteeing the accuracy and safety of the structure.

[0060] S30. Place the wire mesh cage with the hot melt plate fixed into the slurry of the mold frame.

[0061] In this step, a wire mesh cage with a fixed hot-melt plate is placed into the slurry of the mold frame, and the slurry is allowed to aerate and submerge the hot-melt plate. This step, by placing the wire mesh cage with the fixed hot-melt plate into the slurry of the mold frame, allows the slurry to aerate and distribute air evenly, ensuring that the hot-melt plate is completely immersed in the slurry. This lays the foundation for subsequent molding and curing processes, while also promoting the generation and uniform distribution of bubbles, improving the lightweight and thermal insulation performance of the final product.

[0062] S40. Place the mold frame into the curing room for curing.

[0063] In this step, the mold frame is pushed into the curing chamber and cured at room temperature (50 degrees Celsius) for 1 to 3 hours. After it has gained sufficient strength, the upper end of the hot-melt plate extending from the mesh cage connecting piece in step S20 is cut. This step, by placing the mold frame in the curing chamber at room temperature (50 degrees Celsius), ensures that the slurry gradually solidifies in a suitable temperature environment, enhancing its strength and stability. Simultaneously, cutting the upper end of the hot-melt plate facilitates subsequent processing of the cavity, improving production efficiency and product quality.

[0064] S50. After the slurry in the mold frame reaches the preset strength, the concrete blank is obtained.

[0065] In this step, after the slurry inside the mold reaches the preset strength, the preform is demolded and cut on six sides according to the wall panel dimensions to obtain the concrete preform. This step, by waiting for the slurry inside the mold to reach the preset strength before demolding and cutting, ensures that the concrete preform achieves an ideal curing effect, avoids product damage during demolding, and creates suitable conditions for subsequent heating and autoclaving processes, thereby improving production accuracy and product quality.

[0066] S60. Place the concrete blank into an autoclave and vacuum it.

[0067] In this step, the concrete blank is placed in an autoclave and vacuumed or steam-purged. This step, by placing the concrete blank in the autoclave and vacuuming or steam-purged, ensures a stable temperature rise within the autoclave, increases the intensity of the hydration reaction, enhances the amount of crystalline substances formed, improves its lightweight and strength, makes the final product more uniform and stable, and increases production efficiency.

[0068] S70. Inject steam into the autoclave to melt the hot melt plate.

[0069] In this step, less than 5 kg of steam is slowly injected into the autoclave, and the temperature is slowly increased for 1 to 2 hours until it reaches above 180°C. During this process, the concrete substrate gradually strengthens while the hot-melt plate slowly melts, forming the first cavity, the second cavity, and reinforcing ribs. Simultaneously, volatile hydroxyl groups and other organic molecules from the hot-melt plate permeate into the cavity walls, forming a waterproof layer. This step, by slowly injecting steam and heating the autoclave, causes the hot-melt plate to gradually melt and form multiple functional structures, effectively improving the product's strength and functionality. Furthermore, the organic molecules volatilized from the hot-melt plate permeate the cavity walls, forming a waterproof layer, which enhances the durability and waterproofing of the autoclaved aerated concrete (AAC) slab.

[0070] S80. Clean the cavity and insert the insulation plate.

[0071] In this step, the receiving opening on the side with the steel rod hole is cleaned, and the hot-melt plate clumps inside the cavity are removed. Two insulation boards are then inserted into the first and second cavities, respectively. This step, by cleaning the hot-melt plate clumps inside the receiving cavity and inserting the insulation boards, ensures that the hot-melt plate inside the receiving cavity is completely removed, guaranteeing a smooth and clean inner wall of the cavity. This improves the installation accuracy and effectiveness of the insulation boards, ensuring a good match between the thermal insulation performance and the structure.

[0072] S90. Fill the gap between the insulation board and the inner wall of the cavity with the filling material.

[0073] In this step, polyurethane or other materials are filled into the gaps between the insulation board and the cavity wall. This step effectively reduces voids and improves the thermal insulation effect by filling the gaps between the insulation board and the cavity, while also enhancing the overall sealing of the board, improving its compressive strength and waterproofness, and ensuring the thermal insulation performance and service life of the autoclaved aerated concrete board.

[0074] S100, Block the intake port.

[0075] This step involves pouring organic or inorganic materials into the containment opening to form a sealing structure. The sealing structure is flush with the surface of the board, ensuring that the containment cavity is completely sealed. This prevents pollution from the external environment or the entry of substances, improves the sealing performance of the cavity, ensures the safety and stability of the product, and ensures the performance of the autoclaved aerated concrete board.

[0076] 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.
