Currently, the commonly used wall insulation materials are organic and inorganic composite insulation materials. The inorganic surface layer and the organic insulation are connected by adhesive. After long-term erosion by sun exposure, wind, rain, thermal expansion and contraction, cracking, delamination and peeling are likely to occur, and its durability is poor.
[0003] Chinese utility model patent CN213329781U discloses a decorative and thermally insulated integrated wall panel, including a panel, a crash barrier, an insulation layer, a base plate, supporting components, a frame, and connectors. The frame is positioned around the perimeter of the wall panel, and the panel, frame, and base plate form a closed cavity. The crash barrier and the insulation material forming the insulation layer are enclosed within this space. The frame is L-shaped, including edge sealing and mounting edges. There are four edge sealing strips forming a rectangular frame. The insulation material is located within the frame formed by the edge sealing strips, which are parallel to the supporting components. One end of the edge sealing strip is fixed to a first crash barrier via connectors, and the other end is fixed to a second crash barrier via connectors. This disclosed solution requires fastening with connectors, making the assembly process complex and time-consuming. Utility Model Content

Detailed Implementation
[0025] The following is in conjunction with the appendix Figure 1 To be continued Figure 6 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.
[0026] A lightweight, fireproof, high-strength thermal insulation wall panel, such as Figure 1 — Figure 4 As shown, it includes a protective layer and an insulation layer 1 located inside its cavity. The protective layer provides effective protection for the insulation layer 1 inside. The protective layer includes a base plate 2 and a panel 3 located on both sides of the insulation layer 1, and a frame 4 located around the insulation layer 1. In this embodiment, the side of the frame 4 that contacts the insulation layer 1 is flat. Two frames 4 are connected at the corner by corner brackets 5. To facilitate the quick connection of the frames 4 and corner brackets 5, the side of the frame 4 away from the insulation layer 1 is provided with a first insertion groove 6. The corner bracket 5 is provided with an insertion part 7 that is inserted into the first insertion groove 6. The first insertion groove 6 is T-shaped and has a limiting groove 9 inside it. In this embodiment, the limiting groove 9 has a V-shaped cross section. The shape of the insertion part 7 is adapted to the first insertion groove 6. Its body is provided with a limiting flange 10 that cooperates with the limiting groove 9. In this embodiment, the limiting flange 10 has a V-shaped cross section. After the frames 4 and corner brackets 5 are inserted into place, the limiting stop surface 8 on the corner bracket 5 contacts the end of the frames 4.
[0027] like Figure 5 and Figure 6 As shown, the base plate 2 and the panel 3 are provided with bending portions 11 around the perimeter, and the bending portions 11 are all facing the insulation layer 1 side. In order to avoid the bending portions 11 interfering with the corner bracket 5 and failing to be assembled properly, the bending portions 11 are located in the middle area of the perimeter of the base plate 2 and the panel 3, effectively avoiding the corner bracket 5 body.
[0028] To enable the frame 4 to be inserted into the bent portion 11, the frame 4 has a set of second insertion grooves 12 on each side facing the bottom plate 2 and the front panel 3, which are connected to the bent portion 11. In this embodiment, the bent portion 11 is L-shaped, and the shape of the second insertion groove 12 is adapted to the bent portion 11 and is L-shaped. A stop post 13 for limiting the position is provided on the outside of the second insertion groove 12, which can prevent the second insertion groove 12 from falling off the bent portion 11 due to displacement after insertion. Of course, the shape of the bent portion 11 and the second insertion groove 12 can also be C-shaped or other shapes well known to those skilled in the art, as long as they can limit the insertion.
[0029] The base plate 2 and the front plate 3 are steel-plastic composite panels, made of a thin metal sheet and a polymer film. Their surfaces can be customized with various patterns for better decoration. The metal sheet thickness is 0.2–2 mm, and its material is one of galvanized steel, stainless steel, or aluminum. The polymer film thickness is 0.03–0.3 mm, and its material is one or more of ASA, PVC, PE, PP, PET, and PA. In this embodiment, galvanized steel is used, and the metal sheet thickness is 2 mm. In other construction projects, depending on the size of the panel, the metal sheet thickness can be selected from different thicknesses such as 0.2, 0.6, 1.0, 1.2, or 1.5 mm. Depending on the construction requirements, stainless steel or aluminum can also be selected as the metal sheet.
[0030] In this embodiment, the polymer film material is ASA as the surface material of the steel-plastic composite panel. It has strong weather resistance and excellent chemical resistance, and can resist degradation, aging, and fading caused by ultraviolet radiation. It can protect the internal steel plate from corrosion, has good weather resistance, and is not easy to fade. The middle layer is a thin metal plate to increase the overall strength. In some embodiments, the bottom layer can be covered with a layer of PVC film. The insulation layer 1 is one or a combination of vacuum insulation board, foamed polystyrene board, extruded polystyrene board, graphite polystyrene board, phenolic board, and polyurethane board. In this embodiment, the vacuum insulation board is an insulation board with glass fiber as the filler, which has a low heat transfer coefficient and excellent insulation performance after assembly. The frame 4 is made of aluminum alloy, plastic, or aluminum-plastic composite material. In order to increase the fixing strength between the insulation layer 1 and the bottom plate 2 and the front panel 3, an adhesive can be applied between the insulation layer 1 and the bottom plate 2, and between the insulation layer 1 and the front panel 3. This device assembles the insulation layer 1, the base plate 2, and the panel 3 through a mechanical structure. The wall panel structure is stable and has high strength, and the whole assembly adopts a plug-in connection method, making the assembly process more convenient.
