Description

Technical Field

[0001] This application relates to the field of building materials, and in particular to an autoclaved aerated concrete composite exterior wall panel with an internal insulation layer. Background Technology

[0002] As a crucial component of buildings, the performance of exterior walls directly impacts the overall quality and functionality of the building. With the continuous development of the construction industry, people have increasingly higher requirements for the energy efficiency and thermal insulation performance of buildings. The thermal insulation performance of exterior wall panels plays a vital role in reducing building energy consumption and improving indoor comfort. Good exterior wall insulation can reduce indoor heat loss, lower energy consumption for heating and cooling, thereby achieving energy conservation and emission reduction goals, while also contributing to improving the building's service life and stability.

[0003] In traditional construction, various methods are typically employed to improve the thermal insulation performance of exterior walls. One common method is to apply insulating mortar to the exterior of the building walls. This material offers some insulation, is relatively simple to install, and is inexpensive. Another method involves using external insulation boards, which are glued or anchored to the exterior wall surface. These boards offer good insulation performance, and different types and thicknesses can be selected to meet various needs. Additionally, a sandwich wall structure is sometimes used, where an insulation layer is placed between two wall layers to further enhance the wall's thermal insulation performance.

[0004] However, existing insulation methods have certain drawbacks. Traditional insulation mortar is prone to cracking and peeling, leading to a decrease in insulation effectiveness, and its insulation performance is relatively limited. External insulation boards pose a risk of insecure connection with the wall, potentially leading to loosening and falling off during long-term use, and also increasing the load on the building's facade. The construction process of sandwich wall structures is relatively complex, and the bond between the insulation material and the wall may not be tight enough, easily forming thermal bridges and affecting the overall insulation effect. Utility Model Content

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide an autoclaved aerated concrete composite exterior wall panel with a built-in insulation layer.

[0006] An autoclaved aerated concrete composite exterior wall panel with a built-in insulation layer includes a structural wall and a protective wall panel. An insulation layer is disposed on the inner side of the protective wall panel and is connected to the protective wall panel via a first connector. A thermal insulation layer is disposed on the inner side of the insulation layer and is connected to the insulation layer via a second connector. The structural wall is disposed on the inner side of the thermal insulation layer. One end of the first connector is fixed inside the protective wall panel, and the other end of the first connector penetrates the insulation layer and is located inside the thermal insulation layer. One end of the second connector is located inside the insulation layer, and the other end of the second connector penetrates the thermal insulation layer and is located inside the structural wall.

[0007] Preferably, a fixing member is provided at the position where the first connector extends out of the insulation layer.

[0008] Preferably, the insulation layer is made of polystyrene.

[0009] Preferably, the insulation layer is made of polyurethane foam.

[0010] Preferably, a decorative exterior wall panel is provided on the outer side of the protective wall panel.

[0011] Preferably, the insulation layer is provided with a first connecting hole, and the first connector penetrates the insulation layer through the first connecting hole.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. The installation of thermal insulation and heat insulation layers can reduce the loss of indoor heat, reduce energy consumption for heating and cooling, achieve energy conservation and emission reduction, and improve indoor comfort;

[0014] 2. The first connector and the second connector respectively connect the protective wall panel to the insulation layer, the insulation layer to the thermal insulation layer, and the thermal insulation layer to the structural wall. The connection is firm, avoiding safety hazards such as loosening or falling off of the insulation layer, and will not increase the load on the building's exterior facade.

[0015] 3. The insulation layer and the thermal insulation layer are tightly bonded to avoid the formation of cold bridges and improve the overall insulation effect. Attached Figure Description

Detailed Implementation

[0018] The technical solutions in the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0019] This application mainly adopts a composite exterior wall panel solution with built-in multi-layer thermal insulation structure, which achieves the effect of improving the thermal insulation effect of the exterior wall and avoiding the defects of traditional thermal insulation methods. The following is a further detailed description of this application.

[0020] Example 1

[0021] The autoclaved aerated concrete composite exterior wall panel with built-in insulation layer provided in this application embodiment includes a structural wall 8, a protective wall panel 2, an insulation layer 3, a thermal insulation layer 6, a first connector 4, and a second connector 7. The protective wall panel 2, insulation layer 3, thermal insulation layer 6, and structural wall 8 are arranged sequentially from the outside to the inside. The first connector 4 connects the protective wall panel 2 to the insulation layer 3 and thermal insulation layer 6, and the second connector connects the insulation layer 3 and thermal insulation layer 6 to the structural wall 8. This achieves the effect of enhancing the overall thermal insulation performance of the exterior wall and ensuring a firm connection between each layer, preventing problems such as loosening or falling off. This is because the multi-layer structure provides multiple insulation functions, and the connection method of the connectors ensures a tight bond between each layer.

[0022] Specifically, the insulation layer 3 includes materials such as polystyrene. Polystyrene is lightweight and has good thermal insulation properties. It can be made into a board structure and produced through processes such as molding. In some cases, polyurethane foam boards can be used to replace polystyrene, as polyurethane foam boards also have good thermal insulation properties and a certain strength. The insulation layer 3 is provided with a first connecting hole 9, which can be circular, square, or other shapes. It is reserved during the manufacturing process of the insulation layer 3 to facilitate the passage of the first connecting piece 4.

[0023] Specifically, the insulation layer 6 includes polyurethane foam material, etc. Polyurethane foam material has excellent thermal insulation and sealing properties, and it can be filled into the inner side of the insulation layer 3 through on-site foaming. In some scenarios, phenolic foam board can also be used instead of polyurethane foam material, as phenolic foam board also has excellent thermal insulation and fire resistance properties. The insulation layer 6 has a channel for the second connector 7 to pass through; this channel can be pre-drilled during the foaming process or created through machining after molding.

[0024] Specifically, the first connecting member 4 includes a metal rod and a fixing member 5. The metal rod can be made of steel bars, which have certain strength and corrosion resistance. One end can be fixed inside the protective wall panel 2 by pre-embedding, for example, embedding one end of the metal rod during the pouring of the protective wall panel 2. The fixing member 5 can be a nut, etc., and is set at the position where the first connecting member 4 extends out of the insulation layer 3 to further fix the insulation layer 3 and the heat insulation layer 6. After the metal rod passes through the first connecting hole 9 of the insulation layer, the fixing member 5 is installed on the metal rod to make it fit tightly against the insulation layer 3 and prevent the insulation layer 3 and the heat insulation layer 6 from moving relative to each other. In some cases, the first connecting member 4 can also be made of glass fiber reinforced plastic rod, which has the advantages of being lightweight and corrosion resistant.

[0025] Specifically, the second connector 7 includes a screw and a nut. The screw can be a high-strength plastic or metal screw, with one end located inside the insulation layer 3, for example, by inserting it through a pre-drilled hole during the fabrication of the insulation layer 3. The other end penetrates the insulation layer 6 and is fixed inside the structural wall 8 by the nut. This connection method ensures a tight connection between the insulation layer 3, the insulation layer 6, and the structural wall 8. In some environments, expansion bolts can also be used as the second connector 7, achieving a secure connection between the layers through the expansion of the bolts.

[0026] The implementation principle of this embodiment is as follows: By setting up a multi-layered thermal insulation structure, and utilizing the different material properties of the insulation layer 3 and the insulation layer 6, multiple barriers to external heat are achieved, effectively improving the thermal insulation performance of the exterior wall. Simultaneously, the layers are tightly connected together by the first connector 4 and the second connector 7, avoiding problems such as weak connections and easy loosening and falling off that occur in traditional insulation methods. This improves the stability and safety of the exterior wall. Compared with traditional insulation methods, it has better energy-saving effects and a longer service life, representing a significant improvement over existing building exterior wall insulation technology.

[0027] Example 2

[0028] The difference between this embodiment and the previous embodiment is that a decorative exterior wall panel 1 is provided on the outside of the protective wall panel 2. The decorative exterior wall panel 1 includes stone panels and ceramic panels, etc. Stone panels have an aesthetically pleasing appearance, with natural textures and feel, which can enhance the overall grade of the building. They can be installed on the outside of the protective wall panel 2 using a dry-hanging method, fixing the stone panels to the keel pre-installed on the protective wall panel 2 using metal hangers. Ceramic panels have advantages such as rich colors and ease of cleaning. They can be fixed to the protective wall panel using adhesive, applying a special construction adhesive.

[0029] The implementation principle of this embodiment is as follows: the installation of decorative exterior wall panels 1 not only protects the protective wall panels 2, but also beautifies the appearance of the building. Different types of decorative exterior wall panels can be selected according to the style and needs of the building, increasing the aesthetics and diversity of the building, while also providing further protection for the building's exterior walls, improving the durability of the exterior walls, and representing an optimization and upgrade of the existing exterior wall structure.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
