[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Figure 1 This is a cross-sectional view of the composite wall provided in one direction according to an embodiment of the present utility model; Figure 2 This is a cross-sectional view of the composite wall provided in an embodiment of this utility model from another direction.

[0023] This utility model provides a composite wall, including a frame, a mesh membrane, and a composite layer. The frame is located inside the mesh membrane, and the composite layer fills the space between the frame and the mesh membrane. The frame includes a keel support frame and structural building components. The keel support frame includes several keels that are fixedly spliced ​​together. The structural building components include structural beams or columns, and the keel support frame is fixedly connected to the structural building components. In the composite wall provided by this utility model, the structural building components are located inside the mesh membrane. Therefore, the insulation layer inside the mesh membrane can cover the entire frame of the house, and the insulation layer is entirely located inside the mesh membrane, which provides good protection for the insulation layer. In the event of a fire, the mesh membrane can isolate the fire and prevent the fire from spreading rapidly due to the insulation layer catching fire.

[0024] like Figure 1 and Figure 2 As shown, the composite wall provided by this utility model includes structural building columns 11 and / or structural beams 12, and a mesh including an inner mesh 21 and an outer mesh 22. The insulation layer 4 covers the keel support frame and structural building components, and the insulation layer 4 is located between the inner mesh 21 and the outer mesh 22. Therefore, there is no need to lay additional insulation on the outside of the mesh, so that the insulation layer 4 of the wall of this utility model is always supported and protected by the frame and the mesh and is not easy to fall off. At the same time, the mesh separates the insulation layer 4 from the outside. In the event of a fire, the mesh can play a role in isolating the fire and preventing the fire from spreading rapidly due to the insulation layer catching fire.

[0025] For the structural components, existing design schemes can be referenced, and the structure and construction techniques can be selected according to actual needs, which will not be elaborated here. The keel of the keel support frame is preferably made of light steel or aluminum alloy, and the mesh can be made of stainless steel, etc. The mesh should preferably be made of materials with certain structural strength and certain high-temperature resistance and fire resistance, which will not be elaborated here.

[0026] In addition, Figure 1 and Figure 2 In the illustrated embodiment, the building structural components also include a building floor slab 13. This floor slab 13 can be the top floor slab of a building or an intermediate floor slab in a multi-story building. The floor slab 13 and components such as the inner mesh 21 can be fixedly connected by welding or other methods. The outer side of the floor slab 13 is covered by a composite layer and an outer mesh 22, achieving both reinforcement and insulation effects. In some other embodiments, the building structural components may also include other corresponding components, and should not be limited to building structural columns 11, building structural beams 12, and building floor slabs 13. The specific connection method between the building structural components and the composite wall can be selected according to the actual situation, and will not be elaborated here.

[0027] In one preferred embodiment, the keel support frame includes a first connecting frame and a second connecting frame, both of which are fixedly connected to the building structural components. The inner mesh 21 and the outer mesh 22 are respectively attached and fixed to the first connecting frame and the second connecting frame. Figure 1 In the illustrated embodiment, the first connecting frame and the second connecting frame are located on both sides of the building structural column 11, and are both fixedly connected to the building structural column 11 and the building structural beam 12, so that the keel support frame and the building structural components are connected as a whole. The mesh is fixedly installed on the first connecting frame and the second connecting frame, which can enhance the structural strength of the composite wall. The connection method between the first connecting frame (or the second connecting frame) and the building structural components and the mesh can be fixed by welding, riveting, screw connection, etc., which will not be elaborated here.

[0028] like Figure 1 As shown, the keel support frame also includes a keel connector 33, which is used to fix the first connecting frame and the second connecting frame, thereby further improving the structural strength of the composite wall. The connection method between the keel connector 33 and the first connecting frame and the second connecting frame can be welding, riveting, screw connection, etc., which will not be elaborated here.

[0029] like Figure 1 and Figure 2 As shown, in one preferred embodiment, the keel includes a vertical keel 31 arranged in the vertical direction and a horizontal keel 32 arranged in the horizontal direction. The first connecting frame and the second connecting frame are both composed of the vertical keel 31 and the horizontal keel 32 fixedly spliced ​​together. By splicing the vertical keel 31 and the horizontal keel 32 into a grid shape, it can provide more support points for the inner mesh membrane 21 and the outer mesh membrane 22, thereby providing more stable support.

[0030] The vertical keel 31 and the horizontal keel 32 can be fixedly connected by welding, riveting, screws, or other methods, which will not be elaborated here. In addition, the vertical keel 31 and the horizontal keel 32 can be prepared by the manufacturer and then assembled on the construction site to form the first connecting frame and the second connecting frame, or they can be assembled at the manufacturer and then directly installed on the construction site.

[0031] In one preferred embodiment, both the inner mesh 21 and the outer mesh 22 have mesh openings that connect to the spacer cavity between them. The insulation layer 5 is formed by spraying insulation material into the spacer cavity through the mesh openings. By setting the inner mesh 21 and the outer mesh 22 to a mesh structure, during actual construction, the keel support frame and other fixed mechanical structures such as the mesh can be erected first, and then the insulation layer 5 can be sprayed into the mesh after the erection is completed, making the construction process simpler. The insulation layer 5 can be sprayed using existing insulation materials and processes such as polyurethane foam spraying.

[0032] like Figure 2 As shown, the inner mesh 21 and the outer mesh 22 can be a mesh structure composed of diagonally spliced ​​lines, with square holes. The side length of the square (i.e., the diameter of the mesh hole) can be 5mm-20mm. In some other embodiments, the inner mesh 21, the outer mesh 22, and their mesh holes can also have other structures and sizes, which will not be elaborated here.

[0033] like Figure 1 As shown, the composite layer also includes a concrete layer 4, which is also formed by spraying through the mesh structure of the mesh film into the partition cavity. This allows the concrete layer 4 and the insulation layer 5 to be arranged side-by-side along the thickness direction of the wall within the partition cavity. The insulation layer 5 is located on the side facing the outer mesh film 22, enabling it to cover the concrete layer 4, the building structural components, the first connecting frame, and the inner mesh film 21, achieving good insulation performance. The specific spraying processes for the concrete layer 4 and the insulation layer 5 can be found in existing construction methods and will not be elaborated upon here.

[0034] like Figure 1 As shown, in one preferred embodiment, the inner mesh 21 and the outer mesh 22 are symmetrically arranged on both sides of the building structural member. The concrete layer 4 extends from the inner mesh 21 along the thickness direction of the composite wall to the space between the building structural member and the outer mesh 22. The insulation layer 5 extends from the outer mesh 22 along the thickness direction of the composite wall to the concrete layer 4. Based on the above arrangement, the concrete layer 4 can solidify the building structural member, the first connecting frame, the keel connector 33, and the inner mesh 21 into a whole, while the insulation layer 5 fills the space between the concrete layer 4 and the outer mesh 22, which can improve the structural strength of the wall while ensuring good thermal insulation performance.

[0035] like Figure 1 As shown, in one preferred embodiment, the composite wall further includes a finishing layer, comprising an inner wall finish 61 and an outer wall finish 62, which are respectively attached to the inner end of the inner mesh 21 and the outer end of the outer mesh 22. On one hand, the inner wall finish 61 and the outer wall finish 62 can decorate the composite wall; on the other hand, the inner wall finish 61 and the outer wall finish 62 can be made of fire-resistant materials, further improving the safety of the composite wall.

[0036] Based on the composite wall provided by this utility model, the keel support frame and the mesh can be processed and prepared in the factory. Therefore, at the construction site, only the building structural components need to be assembled, and then the keel support frame and mesh are installed based on the building structural components. Then, the composite layer is filled between the inner and outer mesh to complete the basic construction of the composite wall. The whole construction process is simple and quick, and the resulting composite wall has good strength. At the same time, it can provide good protection for the composite layer, especially the insulation layer, and improve its service life.

[0037] When filling the composite layer between the inner and outer mesh membranes, concrete can be sprayed into the mesh membrane through the mesh openings of the inner and outer mesh membranes to form a concrete layer, and insulation material can be sprayed to form an insulation layer. Based on the mesh membrane, keel and other fixed structural components, the insulation layer and concrete layer can be sprayed, which can further simplify the construction process and improve efficiency.

[0038] In addition, the mesh can be made of stainless steel, specifically welded together from steel wires. The keel can be made of I-beams or channel steel, which not only have better mechanical properties, but are also easier to manufacture or purchase, thus reducing the overall production cost.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered by the claims of this utility model.
