In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0057] Example

[0058] This embodiment provides a prefabricated wall, such as Figures 1 to 6 As shown, it includes an inner panel surface 1, an outer panel surface 2, an inner keel 3, an outer keel 4, an insulating connector 5, a vacuum insulating component 6, a first embedded component 7 and a second embedded component 8.

[0059] Among them, Figure 1 As shown, the inner panel 1 and the outer panel 2 are arranged opposite to each other and are made of oriented strand board, corrugated steel sheet, high-density calcium silicate board or gypsum board. The inner keel 3 is fixed to the inner panel 1 by fasteners such as self-tapping screws, and the outer keel 4 is also fixed to the outer panel 2 by fasteners such as self-tapping screws; Figure 2 As shown, the inner purlin 3 and outer purlin 4 are connected by multiple insulating connectors 5 fixed to the sides, allowing the gap between the inner purlin 3 and outer purlin 4 to be adjusted as needed. The number of insulating connectors 5 can be determined based on the specifications of the inner purlin 3 and outer purlin 4. The insulating connectors 5 are made of a non-metallic Class A flame-retardant fiber-reinforced material, such as fiberglass or basalt, and are used to transfer horizontal loads and bear the weight of the outer purlin 4 and outer panels. The insulating connectors 5 effectively block heat conduction between the inside and outside, preventing the formation of cold bridges and reducing the risk of condensation and mold on the interior decorative panels.

[0060] like Figure 1 As shown, a vacuum insulation member 6 is connected between the inner keel 3 and the outer keel 4, and the surface of the vacuum insulation member 6 is treated with an inorganic coating for protection. For example, the vacuum insulation member 6 uses a vacuum insulation panel, whose thermal conductivity is no more than 0.005W / (mK), and the core material is mainly a fumed silica material. The vacuum insulation panel is an ultra-thin and high-efficiency thermal insulation material, which has an insulation performance 5-20 times higher than that of traditional thermal insulation materials. The thickness is thinner than other thermal insulation materials with equivalent performance, which increases system safety. At the same thickness, the thermal resistance value is increased by 80% compared to commonly used thermal insulation materials, thereby reducing cold bridges in the wall, improving the thermal insulation effect of the wall, and making the wall have better energy-saving effects.

[0061] like Figure 1 and Figure 2 As shown, the inner keel 3 adopts a galvanized light steel frame, which can be a rectangular steel tube or a cold-bent thin-walled steel section. The inner keel 3 has a square outer frame, and a plurality of first support rods 31 are connected inside the outer frame. The number of first support rods 31 can be determined according to the load-bearing requirements of the inner keel 3. It can be understood that the more first support rods 31 are used, the more stable the structure of the inner keel 3. Among them, a first cavity is formed between adjacent first support rods 31, and the first cavity is filled with a first grouting material. The first grouting material is laid inside the inner keel 3 to form an inner grouting layer. The inner keel 3 is filled with the inner grouting layer so that the inner keel 3 has a certain compressive strength and increases the stability of the inner keel 3. The first grouting material of the present invention adopts a lightweight concrete thermal insulation grouting material with a combustion grade of A and a bulk density of not less than 600kg / m 3 The compressive strength is not less than 2.0MPa, the thermal conductivity is not greater than 0.14W / (mK), and it has the functions of sound insulation, heat preservation and structural support. The material is neutral and slightly alkaline, providing additional protection for structural corrosion resistance.

[0062] like Figure 1 and Figure 2 As shown, the outer keel 4 has the same structure as the inner keel 3. A second support rod 41 is provided inside the outer keel 4. A second cavity is formed between adjacent second support rods 41. The second cavity is filled with a second grouting material. The second grouting material is laid inside the outer keel 4 to form an outer insulation layer. The second grouting material of the present invention adopts a lightweight concrete insulation grouting material with a combustion grade of A and a bulk density of no more than 300kg / m 3 The thermal conductivity is no more than 0.065W / (mK), which plays a filling and auxiliary insulation role; the material is neutral and slightly alkaline, providing additional protection for structural corrosion resistance.

[0063] This invention utilizes a sandwich insulation structure, with the inner and outer keels 3 and 4 filled with lightweight concrete insulation grouting material. This is cast integrally in the factory, effectively protecting the vacuum insulation element 6. The combined bending and tensile properties of the inner and outer keels 3 and 4, along with the compressive properties of the lightweight concrete insulation grouting material, work together with the skin effect of the inner and outer panels 1 and 2 to form a composite load-bearing structure. This maximizes material performance, reduces steel usage, reduces product weight, and improves product safety. Furthermore, the sandwich insulation structure avoids the quality issues associated with traditional exterior wall insulation systems, such as bulging, cracking, and shedding.

[0064] In other optional implementations, the second cavity may also be filled with dry insulation materials such as rock wool, glass wool, and polymerized polystyrene boards.

[0065] like Figure 3 and Figure 4As shown, the side of the vacuum insulation component 6 is provided with an edge sealing member 9, such as silicone sealant, for sealing the gap between the vacuum insulation component 6, the inner keel 3 and the outer keel 4.

[0066] like Figure 3 As shown, a first connection hole is opened at the top corner of the inner keel 3, and the first connection hole is used to fix the first embedded part 7. The first embedded part 7 is made of stainless steel and is formed by one-time pressing. Figure 5 As shown, the first embedded part 7 includes three first fixing plates 71 connected to each other, and an installation cavity is formed between the surfaces of the first fixing plates 71 that are close to each other, and the installation cavity is adapted to the top corners of the inner keel 3; a plurality of first prefabricated holes 711 are opened on the first fixing plate 71. During installation, the installation cavity is sleeved on the top corners of the inner keel 3, and the first prefabricated holes 711 are aligned with the first connection holes, and then fixedly connected by fasteners such as bolts; the first fixing plate 71 is connected to a plurality of first prefabricated threads 72, which are used for hoisting, transportation, installation and other operations of the prefabricated wall.

[0067] like Figure 4 As shown, a second connection hole is provided at the bottom corner of the inner keel 3. The second connection hole is used to secure the second embedded part 8. The second embedded part 8 includes a second fixing plate 81, which is provided with a second prefabricated hole 82. During installation, the second fixing plate 81 is placed against the side of the inner keel 3, aligning the second prefabricated hole 82 with the second connection hole, and then secured using fasteners such as bolts. The second embedded part 8 also includes a positioning plate 84, which is perpendicular to the second fixing plate 81. The cavity formed by the positioning plate 84 is adapted to the bottom corner of the inner keel 3, so that the second embedded part 8 wraps around the bottom corner of the inner keel 3 during installation. At the same time, the bottom surface of the inner keel 3 is provided with a pre-positioning hole, and the positioning plate 84 is provided with a positioning hole 841. During installation, the pre-positioning hole and the positioning hole 841 cooperate to achieve positioning. The second fixing plate 81 is connected to a plurality of second prefabricated threads 83, which are used for hoisting, transportation, and installation of the prefabricated wall.

[0068] During the processing of the prefabricated wall of this embodiment, a vacuum insulation member 6 is first placed between the inner keel 3 and the outer keel 4, and then the inner keel 3 and the outer keel 4 are fixed by the insulation connector 5. Subsequently, the first grouting material and the second grouting material are poured into the inner keel 3 and the outer keel 4 respectively, and the ultra-thin high-efficiency vacuum insulation board is combined with the lightweight concrete insulation grouting material, which not only improves the thermal value of the building's outer envelope, that is, the external thermal insulation performance, but also enhances the thermal insulation performance, so that the building's outer envelope is insulated in winter and summer, the indoor temperature is warm in winter and cool in summer, and energy consumption is saved; then the inner panel surface 1 is fixed to the inner keel 3, and the outer panel surface 2 is fixed to the outer keel 4, and finally the first embedded part 7 is fixedly connected to the top of the inner keel 3, and the second embedded part 8 is fixedly connected to the bottom of the inner keel 3 to complete the production of the prefabricated wall.

[0069] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible.
