[0003] Most of the current thermal insulation walls are of an integral structure, which is not convenient for freely assembling according to the construction area;

[0004] In the existing public technical solution, a thermal insulation wall with a multi-layer composite fireproof mortar structure disclosed in the publication number CN217268160U includes a base layer and a thermal insulation wall. The shape of the thermal insulation wall is hexagonal. An adhesive layer is coated on one side of the thermal insulation wall. Through the settings of the thermal insulation wall, the adhesive layer and the reflective layer, when in use, the formed thermal insulation wall is divided into hexagons, and when encountering a position with a narrow space and inconvenient construction, the hexagonal thermal insulation wall can be used for splicing.

[0005] When the above technical solution is actually implemented, the hexagonal thermal insulation wall is directly fixed by pasting through the adhesive layer, and the fixing effect is average. Once the adhesive layer ages, it will affect the stability of the thermal insulation wall. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides a technical solution:

[0028] Please refer to Figures 1 to 4 , a heat-insulating wall with a multi-layer composite structure, including a prefabricated wall 1. A splicing card slot 4 is provided on the prefabricated wall 1, and the splicing card slot 4 is divided into an upper notch and a lower notch. Two groups of prefabricated walls 1 are assembled with each other through the splicing card slot 4. A glass fiber mesh 2 is provided at the bottom of the prefabricated wall 1, and a wall base body is provided at the bottom of the glass fiber mesh 2. A fixing component 3 is provided between the glass fiber mesh 2 and the prefabricated wall 1;

[0029] The fixing component 3 includes a plugging outer cylinder 301 with a cone-shaped structure installed at the grid intersection of the glass fiber mesh 2 and a plugging inner cylinder 302 installed at the central position of the prefabricated wall 1. Four fixing nails 306 are fixedly provided below the plugging outer cylinder 301, and the fixing nails 306 are located around the grid intersection of the glass fiber mesh 2. An adhesive is also filled inside the plugging outer cylinder 301, and a sealing film 304 is provided above the adhesive. A pressing plate 305 is provided around the plugging outer cylinder 301, and the fixing nails 306 are located at the bottom of the pressing plate 305. A fixing plate 303 is provided at the top of the plugging inner cylinder 302, and the inside of the plugging inner cylinder 302 is a hollow structure.

[0030] By adopting the above technical solution, a layer of fiberglass mesh 2 is fixed on the wall substrate through cement mortar or adhesive for priming, and is fixed on the fiberglass mesh 2 through fixing nails 306. The fixing nails 306 penetrate into the wall substrate, and the pressing plate 305 presses the grid intersection points of the fiberglass mesh 2 to prevent the fiberglass mesh 2 from falling off. Subsequently, the prefabricated wall 1 is sequentially installed on the fiberglass mesh 2, and the inserted inner cylinder 302 is installed in the prefabricated wall 1. The inserted inner cylinder 302 is inserted into the inserted outer cylinder 301 to achieve clearance fit. At the same time, in order to make up for the gap between the conical inserted inner cylinder 302 and the inserted outer cylinder 301, an adhesive is filled in the inserted outer cylinder 301. When the inserted inner cylinder 302 is installed, the sealing film 304 can be punctured, and the adhesive in the sealing film 304 flows out to fill the entire inserted inner cylinder 302 and the inserted outer cylinder 301. Since the inserted inner cylinder 302 is a hollow structure, it is convenient to position the exterior finish.

[0031] Specifically, as Figure 5 shown, the prefabricated wall 1 includes a concrete outer layer 102. Inside the concrete outer layer 102, a heat insulation layer 103, a sound insulation layer 104, a fire protection layer 105, and a thermal insulation layer 106 are sequentially arranged from top to bottom. The prefabricated wall 1 further includes an assembly hole penetrating through the concrete outer layer 102, the heat insulation layer 103, the sound insulation layer 104, the fire protection layer 105, and the thermal insulation layer 106. An installation ring 101 is arranged inside the assembly hole. Both the inserted inner cylinder 302 and the inserted outer cylinder 301 penetrate through the inside of the installation ring 101, and the outer diameter of the fixing plate 303 is larger than the outer diameter of the installation ring 101.

[0032] By adopting the above technical solution, the prefabricated wall 1 is made by wrapping the heat insulation layer 103, the sound insulation layer 104, the fire protection layer 105, and the thermal insulation layer 106 with the concrete outer layer 102. First, concrete is poured in the mold to form the bottom layer of the concrete outer layer 102. After sequentially placing the heat insulation layer 103, the sound insulation layer 104, the fire protection layer 105, and the thermal insulation layer 106, concrete is then covered to achieve complete wrapping. According to the installation position of the prefabricated wall 1, different molds are used to form certain splicing card slots 4. The two prefabricated walls 1 are mutually clamped by the splicing card slots 4. The installation ring 101 is a cylindrical structure used to position the heat insulation layer 103, the sound insulation layer 104, the fire protection layer 105, and the thermal insulation layer 106.

[0033] Working principle: Fix a layer of fiberglass mesh 2 on the wall substrate by using cement mortar or adhesive for priming, and fix it on the fiberglass mesh 2 with fixing nails 306. The fixing nails 306 penetrate into the wall substrate, and the pressing plate 305 presses the grid intersection points of the fiberglass mesh 2. Then, the prefabricated wall 1 is sequentially installed on the fiberglass mesh 2, and the inserted inner cylinder 302 is installed in the prefabricated wall 1. The inserted inner cylinder 302 is inserted into the inserted outer cylinder 301, piercing the sealing film 304, and the adhesive in the sealing film 304 flows out to fill the entire inserted inner cylinder 302 and the inserted outer cylinder 301. The prefabricated wall 1 is made of a concrete outer layer 102 wrapping an insulation layer 103, a sound insulation layer 104, a fireproof layer 105, and a heat preservation layer 106, having a good effect of heat preservation and heat insulation.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
