[0032] Specifically, on the one hand, the wall structure 1 has excellent thermal insulation and heat insulation properties; the wall structure 1 adopts a double-layer insulation system, namely an outer insulation layer 11 and an inner insulation layer 13 overlapped with each other, wherein the material of the outer insulation layer 11 may be but is not limited to rock wool, which is an inorganic fiberboard made of basalt as the main raw material and processed by high-temperature melting. The thickness of the outer insulation layer 11 may be 100 mm, with a tolerance within the range of 4 mm; the material of the inner insulation layer 13 may be but is not limited to aerogel felt, which is a flexible insulation felt with nano-silicon dioxide or metal aerogel as the main material, and is compounded with carbon fiber or ceramic glass fiber wool or pre-oxidized fiber felt through a special process, and the thickness of the inner insulation layer 13 It can be 20mm, and the tolerance is within the range of 2mm above and below; by arranging an outer insulation layer 11 and an inner insulation layer 13 with a certain thickness, the effect of coordinated insulation between the inside and the outside is achieved, so that the thermal insulation effect of the wall structure 1 is excellent; in the outer insulation layer 11, a main support 12 is arranged, and the main support 12 can be a keel, but in the inner insulation layer 13, a secondary support 16 is arranged, and the secondary support 16 is made of non-metallic material, which can be but not limited to a wooden keel or a high-density polypropylene keel, replacing the keel of metal material, preventing the generation of a thermal bridge effect at the metal support, thereby achieving a thermal insulation effect and forming a continuous and complete insulation layer, that is, the inner insulation layer 13 and the secondary keel cooperate to form a thermal insulation domain layer, so that the thermal insulation effect of the wall structure 1 is excellent.

[0033] On the other hand, the wall structure 1 has excellent waterproof and airtight properties; the outer side of the wall along the thickness direction is covered with a first waterproof layer 14, and the first waterproof layer 14 can be but not limited to a galvanized steel plate, and the galvanized steel plate is a welded steel plate with a hot-dip or electroplated zinc layer on the surface, and the thickness of the galvanized steel plate can be 1 mm, which has an outer waterproof effect to prevent external rainwater from wetting the insulation layer; the inner insulation layer 13 is covered with a vapor barrier layer 15 on the side away from the outer insulation layer 11, and the vapor barrier layer 15 can be but not limited to a moisture-proof vapor barrier film, that is, a moisture-proof vapor barrier film is specially paved on the inner side of the wall to prevent indoor water vapor from being discharged into the insulation layer, thereby improving the waterproof performance of the wall and ensuring the excellent airtightness of the wall.

[0034] In this embodiment, a double-layer insulation system is adopted, namely an outer insulation layer 11 and an inner insulation layer 13, and the outer insulation layer 11 uses high-efficiency insulation materials such as rock wool, and the inner insulation layer 13 uses high-performance flexible insulation materials such as aerogel felt, and the thickness of each layer is strictly controlled, so as to achieve the effect of coordinated insulation between the inside and the outside, significantly improve the overall insulation performance of the wall structure 1, contribute to energy conservation and emission reduction, and improve the comfort of the living or working environment.

[0035] In this embodiment, a secondary support 16 made of non-metallic material, such as a wooden keel or a high-density polypropylene keel, is used in the inner insulation layer 13, which effectively avoids the thermal bridge effect that may be caused by the metal support, reduces the transfer and loss of heat, forms a continuous and complete insulation layer, further enhances the heat insulation effect of the wall structure 1, and improves energy utilization efficiency.

[0038] In some embodiments, in combination Figure 1As shown, it also includes a second waterproof layer 17, which is covered on the side of the first waterproof layer 14 away from the outer insulation layer 11. The second waterproof layer 17 can be but is not limited to an aluminum plate curtain wall or a stone curtain wall. The second waterproof layer 17 provides an additional protective layer for the wall structure 1, further enhancing its waterproof performance; the aluminum plate curtain wall or the stone curtain wall has high durability and anti-aging ability, can resist the erosion of the natural environment, and keep the wall in a good state for a long time. At the same time, the second waterproof layer 17 is covered on the outside of the first waterproof layer 14 to form an additional waterproof barrier, and the second waterproof layer 17 is relatively easy to clean and maintain compared to the first waterproof layer 14, which greatly reduces the later maintenance cost and has strong practicality.

[0039] In some embodiments, in combination Figure 1 As shown, it also includes a fireproof layer 18 covering the side of the vapor barrier layer 15 away from the inner insulation layer 13. The fireproof layer 18 can be but is not limited to a flame retardant board. The flame retardant board is a man-made board made by adding flame retardants to a board production line through a complex process. This type of board can effectively suppress the spread of fire and reduce the risk of fire when encountering a fire source. Among them, the thickness of the fireproof layer 18 can be 10 mm. This thickness not only ensures the fireproof effect of the fireproof layer 18, but also avoids the waste of space or cost increase caused by excessive increase in wall thickness, and is highly practical.

[0040] In some embodiments, in combination Figure 1 As shown, it also includes a decorative panel 19, which is arranged on the side of the fireproof layer 18 away from the external insulation layer 11, that is, located on the indoor side of the wall. The decorative panel 19 can be but not limited to a calcium silicate board, which plays a role in wall decoration. The calcium silicate board is light in weight, easy to carry and operate during construction, and has strong practicality.

[0041] In some embodiments, in combination Figure 1 As shown, the main support 12 is composed of multiple first keels connected, and the first keels are embedded in the outer insulation layer 11. The multiple first keels are interconnected to form a stable support frame, and are urgently combined with the insulation material in the outer insulation layer 11, thereby improving the stability and insulation performance of the wall structure 1.

[0042] In some embodiments, in combination Figure 1 As shown, the secondary support 16 is composed of multiple second keels connected together, and the second keels are embedded in the inner insulation layer 13. The second keels are made of non-metallic material, and can be specifically lightweight and high-strength keels such as wooden keels or high-density polypropylene keels.

The connecting piece 191 can be a mounting code, and the decorative panel 19 is fixed to the fireproof layer 18 with the help of the mounting code. During the installation process, the mounting code is first fixed on the fireproof layer 18, and then the mounting holes reserved on the decorative panel 19 are aligned with the corresponding parts on the mounting code, and screws, rivets or other fasteners are used to firmly connect them together to achieve the installation and fixation of the decorative panel 19.

[0044] In some embodiments, in combination Figure 1 As shown, the thickness of the outer insulation layer 11 is D1, wherein: D1 = 100 mm ± 4 mm. For the outer insulation layer 11, a thickness of 100 mm can provide sufficient insulation effect under most climatic conditions, reduce building energy consumption, and at the same time not be too thick to affect the construction of the wall structure 1, taking into account both insulation performance and wall construction.

[0045] In some embodiments, in combination Figure 1 As shown, the thickness of the inner insulation layer 13 is D2, where: D2 = 20 mm ± 2 mm. For the inner insulation layer 13, a thickness of 20 mm can form an effective insulation barrier indoors to slow down the loss of indoor heat, while not being too thick to affect the utilization of the indoor space, thereby maximizing insulation and benefits.
