[0029] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0030] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of a lightweight prefabricated composite thermal insulation exterior wall panel provided in an embodiment of this application. A lightweight prefabricated composite thermal insulation exterior wall panel may include: wall panel assembly 000 and connecting assembly 001.

[0031] A wall panel assembly 000 in a lightweight prefabricated composite insulated exterior wall panel may include: a load-bearing layer 100, a first support layer 200, and an insulation filling layer 300. The load-bearing layer 100 enhances the seismic and impact resistance of the lightweight prefabricated composite insulated exterior wall panel.

[0032] Please refer to the following in this application: Figure 2 , Figure 2 This is a cross-sectional view of a lightweight prefabricated composite thermal insulation exterior wall panel provided in an embodiment of this application. The first support layer 200 of the wall panel assembly 000 can be located on one side of the reinforcing insulation filling layer 300 of the load-bearing layer 100. Here, the first support layer 200 may include: a plurality of connecting wing plates 201 and a plurality of support receiving plates 202 corresponding to and fixedly connected to the connecting wing plates 201. The connecting wing plates 201 can be fixedly connected to the load-bearing layer 100, thus achieving a fixed connection between the first support layer 200 and the load-bearing layer 100.

[0033] It should be noted that the cross-sectional shape of the support receiving plate 202 can be trapezoidal, and the bottom edge of the support receiving plate 202 can be fixedly connected to the connecting wing plate 201. In this way, the support receiving plate 202 and the connecting wing plate 201 can fit together to form the first support layer 200, firmly serving as a supporting link for the lightweight prefabricated composite thermal insulation exterior wall panel. For example, the connecting wing plate 201 and the load-bearing layer 100 can be fixedly connected using self-tapping screws.

[0034] In the lightweight prefabricated composite insulated exterior wall panel, the insulation filling layer 300 is located between the supporting receiving plate 202 and the load-bearing layer 100, and the insulation filling layer 300 can be fixedly connected to the supporting receiving plate 202 and the load-bearing layer 100. In this way, the insulation filling layer 300 can stably form an integral structure with the first supporting layer 200 and the load-bearing layer 100, and provide sufficient insulation performance for the lightweight prefabricated composite insulated exterior wall panel.

[0035] To further improve the overall integrity of lightweight prefabricated composite insulated exterior wall panels, please refer to... Figure 3 , Figure 3 This is a schematic diagram illustrating the mating relationship between a connecting component and a wall panel component according to an embodiment of this application. The edge of the connecting wing plate 201 coincides with the edge of the load-bearing layer 100. The connecting component 001 includes: a first connecting member L1 that wraps around the left edge of the connecting wing plate 201 and the left edge of the load-bearing layer 100; one side of the first connecting member L1 is fixedly connected to the left edge of the connecting wing plate 201 and the left edge of the load-bearing layer 100; the other side of the first connecting member L1 has a connecting groove; and a second connecting member L2 that wraps around the right edge of the connecting wing plate 201 and the right edge of the load-bearing layer 100; one side of the second connecting member L2 is fixedly connected to the right edge of the connecting wing plate 201 and the right edge of the load-bearing layer 100; the other side of the second connecting member L2 has a connecting protrusion. Thus, through the connection between the first connecting member L1 and the second connecting member L2, the relevant structures of the lightweight prefabricated composite insulated exterior wall panel can all be connected into a cohesive, load-bearing structure, thereby further improving the seismic performance of the lightweight prefabricated composite insulated exterior wall panel.

[0036] In summary, this application provides a lightweight prefabricated composite insulated exterior wall panel, comprising: a wall panel assembly and a connecting assembly. The wall panel assembly includes: a load-bearing layer, a first support layer, and an insulation filling layer. The load-bearing layer enhances the seismic and impact resistance of the lightweight prefabricated composite insulated exterior wall panel. Through the cooperation of the first support layer and the insulation filling layer, the insulation filling layer can work well with the load-bearing layer, thereby improving the seismic performance of the lightweight prefabricated composite insulated exterior wall panel while ensuring good insulation performance. The cross-sectional shape of the support receiving plate can be trapezoidal, and the bottom edge of the support receiving plate can be fixedly connected to the connecting wing plate. In this way, the support receiving plate and the connecting wing plate can form the first support layer in a relatively close fit, serving as a stable supporting link for the lightweight prefabricated composite insulated exterior wall panel. The insulation filling layer in the lightweight prefabricated composite insulated exterior wall panel is located between the support receiving plate and the load-bearing layer, and the insulation filling layer can be fixedly connected to the support receiving plate and the load-bearing layer. In this way, the thermal insulation filling layer can stably form an integral structure with the first support layer and the load-bearing layer, providing sufficient thermal insulation performance for the lightweight prefabricated composite thermal insulation exterior wall panel. Through the connecting effect of the connecting components, the relevant structures of the lightweight prefabricated composite thermal insulation exterior wall panel can all be connected into a cohesive structural system, thereby further improving the seismic performance of the lightweight prefabricated composite thermal insulation exterior wall panel.

[0037] In the embodiments of this application, please refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of a thermal insulation filling layer provided in an embodiment of this application. The thermal insulation filling layer 300 includes: a first adhesive layer 301 connected to the support receiving plate 202 and the load-bearing layer 100; a first fiber layer 302 located on the side of the first adhesive layer 301 opposite to the support receiving plate 202; a second adhesive layer 303 located on the side of the first fiber layer 302 opposite to the first adhesive layer 301; and a thermal insulation structural layer 304 located on the side of the second adhesive layer 303 opposite to the first fiber layer 302. The first adhesive layer 301 and the second adhesive layer 303 can apply adhesive force to the surrounding structure. The first adhesive layer 301 can firmly ensure that the first fiber layer 302 in the thermal insulation filling layer 300 is tightly connected with the support receiving plate 202 and the load-bearing layer 100. The second adhesive layer 303 can ensure that the first fiber layer 302 is tightly connected with the thermal insulation structural layer 304. In this way, the thermal insulation filling layer 300 fully serves as the thermal insulation structural layer 304 of the lightweight prefabricated composite thermal insulation exterior wall panel and works in conjunction with the lightweight prefabricated composite thermal insulation exterior wall panel.

[0038] Furthermore, the first fiber layer 302 can further improve the impact resistance of the insulation filling layer 300, preventing damage to the insulation structural layer 304 when the lightweight prefabricated composite insulation exterior wall panel is subjected to external forces. For example, the insulation structural layer 304 is wrapped by the first fiber layer 302, which can be a carbon fiber structure. The strong tensile strength of the carbon fiber structure provides sufficient safety protection for the insulation structural layer 304, thereby improving the seismic performance of the insulation filling layer 300.

[0039] Please refer to the following in this application: Figure 5 , Figure 5 This is a structural schematic diagram of another lightweight prefabricated composite insulated exterior wall panel provided in this application embodiment. The lightweight prefabricated composite insulated exterior wall panel may further include: an assembly plate 400 located on the first support layer 200 away from the insulation filling layer 300, and an impact-resistant layer 500 located on one side of the insulation filling layer between the connecting wing plate 201 and the assembly plate 400. The assembly plate 400 can further improve the overall performance of the lightweight prefabricated composite insulated exterior wall panel, and the impact-resistant layer can significantly improve the seismic performance of the lightweight prefabricated composite insulated exterior wall panel.

[0040] For example, the assembly plate 400 and the support receiving plate 202 can be fixedly connected by self-tapping screws. The impact-resistant layer 500 may include: multiple evenly distributed tie rods 501 and foamed concrete 502. One end of the tie rod 501 is fixedly connected to the assembly plate 400, and the other end of the tie rod 501 is fixedly connected to the connecting wing plate 201. The foamed concrete 502 is used to fill the cavity structure formed by the connecting wing plate 201, the support receiving plate 202, and the assembly plate 400. Here, the foamed concrete 502 can be cast into the cavity structure. In this case, the connecting wing plate 201, the support receiving plate 202, and the assembly plate 400 can function as a casting template, and the tie rods 501 can act as reinforcement within the foamed concrete 502 to enhance mechanical properties.

[0041] In the embodiments of this application, please refer to Figure 6 , Figure 6 This is a structural schematic diagram of another lightweight prefabricated composite insulated exterior wall panel provided in this application embodiment. The lightweight prefabricated composite insulated exterior wall panel further includes: a third connector L3 connected to the upper edge of the load-bearing layer 100, the upper edge of the first support layer 200, the upper edge of the insulation filling layer 300, the upper edge of the assembly panel 400, and the upper edge of the impact-resistant layer 500; and a fourth connector L4 connected to the lower edge of the load-bearing layer 100, the lower edge of the first support layer 200, the lower edge of the insulation filling layer 300, the lower edge of the assembly panel 400, and the lower edge of the impact-resistant layer 500. The third connector L3 and the fourth connector L4 further improve the overall performance of the lightweight prefabricated composite insulated exterior wall panel.

[0042] It should be noted that the third connector L3 may have a transverse connecting component. The width direction of the transverse connector is perpendicular to the plane of the load-bearing layer 100, and the length and thickness directions of the transverse connector are parallel to the plane of the load-bearing layer 100. Through the transverse connector, the lightweight prefabricated composite insulated exterior wall panel can be connected to a panel structure perpendicular to its own plane. For example, the lightweight prefabricated composite insulated exterior wall panel can be connected to a floor slab structure.

[0043] To further improve the stability of the lightweight prefabricated composite insulated exterior wall panel, the fourth connector L4 can have longitudinal and transverse supports. There can be multiple longitudinal and transverse supports, at least a portion of which is fixedly connected to the load-bearing layer 100, and another portion of which is fixedly connected to the assembly panel 400. The longitudinal and transverse supports are connected to the supporting plane where the lightweight prefabricated composite insulated exterior wall panel is located. Thus, through the fourth connector L4, the stability of the connection between the lightweight prefabricated composite insulated exterior wall panel and the supporting plane can be further improved, thereby ensuring the stability of the lightweight prefabricated composite insulated exterior wall panel.

[0044] This application also provides another feasible method for implementing a lightweight prefabricated composite insulated exterior wall panel. The lightweight prefabricated composite insulated exterior wall panel may further include a second support layer and a second insulation filling layer 300. The lightweight prefabricated composite insulated exterior wall panel has a symmetrical structure with the load-bearing layer 100 as the plane of symmetry. That is, the second support layer may be distributed relative to the first support layer 200 with the load-bearing layer 100 as the plane of symmetry, and the second insulation filling layer 300 may be distributed relative to the first insulation filling layer 300 with the load-bearing layer 100 as the plane of symmetry. Thus, through this duplex symmetrical wall structure, the thermal insulation capacity and seismic performance of the lightweight prefabricated composite insulated exterior wall panel can be further improved.

[0045] In summary, this application provides a lightweight prefabricated composite insulated exterior wall panel, comprising: a wall panel assembly and a connecting assembly. The wall panel assembly includes: a load-bearing layer, a first support layer, and an insulation filling layer. The load-bearing layer enhances the seismic and impact resistance of the lightweight prefabricated composite insulated exterior wall panel. Through the cooperation of the first support layer and the insulation filling layer, the insulation filling layer can work well with the load-bearing layer, thereby improving the seismic performance of the lightweight prefabricated composite insulated exterior wall panel while ensuring good insulation performance. The cross-sectional shape of the support receiving plate can be trapezoidal, and the bottom edge of the support receiving plate can be fixedly connected to the connecting wing plate. In this way, the support receiving plate and the connecting wing plate can form the first support layer in a relatively close fit, serving as a stable supporting link for the lightweight prefabricated composite insulated exterior wall panel. The insulation filling layer in the lightweight prefabricated composite insulated exterior wall panel is located between the support receiving plate and the load-bearing layer, and the insulation filling layer can be fixedly connected to the support receiving plate and the load-bearing layer. In this way, the thermal insulation filling layer can stably form an integral structure with the first support layer and the load-bearing layer, providing sufficient thermal insulation performance for the lightweight prefabricated composite thermal insulation exterior wall panel.
