[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0039] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0040] The embodiment of the present application provides a wall structure, such as Figures 1 to 5 As shown, the wall structure includes a wall frame 1, an inner panel group 2, and an outer panel group 3. The inner panel group 2, the outer panel group 3 and the wall frame 1 together form a cavity, and the cavity is filled with foamed concrete; the outer panel group 3 includes a curtain wall keel and a decorative panel 31. The curtain wall keel is fixed on the wall frame 1 and is installed with a decorative panel 31.

[0041] The inner panel group 2 can be formed by combining multiple panels or a single panel. For example, the inner panel group 2 in the embodiment of the present application can be a 10 mm thick cement fiber board, which is fully coated with water-resistant putty twice and painted three times during manufacturing.

[0042] The inner and outer panels 2, 3, and wall frame 1 together form a cavity, which is filled with foamed concrete. In practical applications, the inner and outer panels 2, 3 can be complete rectangular panels to form the cavity; alternatively, they can be rectangular panels with holes to form an annular or U-shaped cavity, suitable for walls with doors and windows.

[0043] The outer panel assembly 3 includes a curtain wall keel and decorative panels 31. The curtain wall keel is fixed to the wall frame 1 at both ends along its length, for example, by welding. The decorative panels 31 are secured to the curtain wall keel using a combination of adhesive and self-tapping screws to ensure secure attachment.

[0044] In addition, the curtain wall keel can also be connected to the foam concrete casting, that is, the curtain wall keel is partially inserted into the foam concrete before it is completely solidified; of course, the curtain wall keel can also be fixed by bolts or other means after the foam concrete is completely solidified. The decorative panel 31 is fixed to the curtain wall keel by bolts or other means.

[0045] In the solution provided in the embodiments of the present application, a cavity is formed between the outer panel group 3 and the inner panel group 2 to be filled with foamed concrete. The cavity can be pre-sized to facilitate control of the filling amount and thickness of the foamed concrete. The decorative panel 31 and the foamed concrete are connected via curtain wall keels, eliminating the need for additional connecting members 13. The curtain wall keels can be directly inserted into the foamed concrete for securement. This connection method is simple and reliable, and the decorative panel 31 can be directly fixed to the curtain wall keel, making it easy to operate. This wall structure does not require the installation of additional connecting members 13, and the foamed concrete can be poured using flat molds, shortening the overall construction period.

[0046] In an exemplary embodiment, Figure 1 As shown, the wall frame 1 includes beams 11 , columns 12 and connecting members 13 . The beams 11 and columns 12 form a rectangular frame structure. The beams 11 and columns 12 are connected by the connecting members 13 .

[0047] There are two beams 11, located at the top and bottom of the frame; there are two columns 12, one on each side of the frame. The beams 11 and columns 12 form a rectangular frame. These beams 11 and columns 12 are connected by connecting members 13. These connecting members 13 can be used to connect the upper and lower walls. Specifically, the connecting member at the top of the lower wall is connected to the connecting member at the bottom of the upper wall using bolts or other means, thereby connecting the upper and lower walls.

[0048] In an exemplary embodiment, Figure 4 and Figure 5As shown, the connecting member 13 is provided with a connecting hole 131, which extends along the height direction of the wall; the fixing piece is inserted into the connecting hole 131 of the connecting member 13 of the upper and lower walls to connect the upper and lower walls.

[0049] The fixing member can be a bolt, which passes through the connection hole of the lower wall connection member, is inserted into the connection hole of the upper wall connection member, and is tightened by a nut to fix the two connection members tightly together, thereby realizing the connection between the upper and lower walls.

[0050] Of course, the upper and lower walls can also be connected at other points, and are not limited to being connected at the connecting member 13.

[0051] In an exemplary embodiment, Figure 4 and Figure 5 As shown, the connecting member 13 is further provided with an operating cavity 132 , which is communicated with the connecting hole 131 . The operating cavity 132 is provided with an opening perpendicular to the extending direction of the connecting hole 131 ; the operating cavity 132 serves as an operating space for installing a fixing part.

[0052] After the upper and lower walls are placed in place, the fixings can be installed from the operating cavity 132 , that is, bolts are placed from the operating cavity 132 , passed through the connecting holes 131 of the two connecting members 13 , and the nuts are tightened.

[0053] After setting up the operating cavity 132, there is no need to place the fixings in advance. The fixings can be connected after the wall is put in place. The operation is simple and the assembly accuracy requirements for the cavity are reduced. The subsequent connection of the upper and lower walls can be achieved without excessive lifting accuracy.

[0054] In an exemplary embodiment, Figure 4 As shown, a positioning hole 133 is also provided on the connecting member 13, and the positioning hole 133 and the connecting hole 131 extend in the same direction; the positioning member passes through the positioning hole 133 of the connecting member 13 of the upper and lower walls, so that the fixing member can be inserted into the connecting hole 131 of the connecting member 13 of the upper and lower walls.

[0055] Positioning holes 133 are also provided on the connecting member 13. The positioning piece is placed on the lower wall in advance, and when the upper wall is hoisted, the positioning piece is passed through the positioning holes 133 of the upper and lower connecting members 13 to achieve preliminary positioning of the wall, which facilitates the subsequent precise connection of the upper and lower walls with the fixing parts.

[0056] In an exemplary embodiment, Figure 1 As shown, the wall structure further includes a support assembly 4 , which is arranged in the cavity to improve the strength of the wall frame 1 .

[0057] The support assembly 4 is welded and fixed to the beam 11 or column 12 in the wall frame 1. The provision of the support assembly 4 can not only improve the strength of the frame, but also provide a point for fixing the aforementioned inner panel group 2 (cement fiber board), that is, the inner panel group 2 can be fixed to the support assembly 4 by means of self-tapping screws or the like.

[0058] In an exemplary embodiment, Figure 1 and Figure 3 As shown, the support assembly 4 is provided with a through hole 41 for the foamed concrete to pass through.

[0059] The support assembly 4 can be a C-shaped keel, a U-shaped keel or an I-shaped keel.

[0060] Holes are set on the support component 4 to allow the foamed concrete to pass through, which can effectively avoid bubbles from being generated in the cavity where the support component 4 is set during the foamed concrete flat mold pouring process, avoid problems such as uneven pouring, and effectively improve the quality of the wall.

[0061] In an exemplary embodiment, Figure 1 As shown, the wall frame 1 further includes an inner frame 14 , which is located inside the rectangular frame structure formed by the beams 11 and the columns 12 so that the cavity forms an annular cavity; the inner frame 14 is connected and fixed to the beams 11 or the columns 12 .

[0062] The inner plate group 2 and the outer plate group 3 can be rectangular plates with holes to form an annular cavity, which is suitable for the situation where doors and windows are opened on the wall.

[0063] The aforementioned beams 11 and columns 12 form a rectangular frame, while the inner frame 14 is a smaller rectangular frame. The beams 11 and columns 12 form the outer frame, while the inner frame 14 serves as the inner frame, giving the wall frame 1 an overall annular shape. Together with the inner panel set 2 and the outer panel set 3, which have openings, they ultimately form a wall with window openings.

[0064] The inner frame 14 is connected and fixed to the beam 11 or column 12. An additional component can be provided to connect the inner frame 14 to the beam 11 or column 12, or one or two sides of the inner frame 14 can be extended to the beam 11 or column 12 in the length direction and directly welded to the beam 11 or column 12.

[0065] It should be understood that the explanation here is only illustrative of "setting windows on the wall to form an annular cavity". In actual applications, there is also a situation where "doors are set on the wall to form a U-shaped cavity". In this case, the inner skeleton 14 is adaptively adjusted to form a U-shaped cavity, which will not be repeated here.

[0066] In an exemplary embodiment, there are multiple curtain wall keels (not shown in the figure), and extruded polystyrene boards 32 are filled between adjacent curtain wall keels to further improve the thermal insulation performance of the wall.

[0067] A plurality of extruded polystyrene boards 32 are filled between adjacent curtain wall keels, which does not affect the arrangement of the curtain wall keels and can also ensure a good thermal insulation effect.

[0068] The thickness of the extruded polystyrene board 32 is 50-200 mm, for example, the thickness of the extruded board can be 80 mm.

[0069] The thickness of foamed concrete is 90-250mm, for example, the thickness of foamed concrete can be 140mm.

[0070] The thickness of the cement fiber board is 8-14 mm, for example, the thickness of the cement fiber board can be 10 mm.

[0071] In an exemplary embodiment, the wall structure further includes a waterproof and breathable membrane (not shown in the figure) laid on the inner side of the decorative panel 31 .

[0072] By adding a waterproof and breathable membrane, the waterproof performance of the wall can be improved and the quality of the wall can be enhanced.

[0073] In the specific production process of the factory, the production process of the above wall can be:

[0074] 1. Wall frame forming: formed by welding beams, columns, connecting components and internal skeleton;

[0075] 2. Install support components (light steel keel or truss reinforcement);

[0076] 3. Fix the inner panel group (10mm cement fiber board) to the support assembly with self-tapping screws;

[0077] 4. Pour concrete with flat formwork within the wall frame, and support the formwork around the wall and the door and window openings to prevent leakage;

[0078] 5. Install curtain wall keels on the foamed concrete, install extruded polystyrene boards between the curtain wall keels, and fix the decorative panels on the curtain wall keels; lay a waterproof and breathable membrane on the inner side of the decorative panels (close to the curtain wall keel);

[0079] 6. Apply 2 coats of water-resistant putty and 3 coats of paint on the indoor side of the wall (10mm cement fiber board side).

[0080] An embodiment of the present application further provides a prefabricated room module, which includes the aforementioned connection structure between the wall and the support column.

[0081] The prefabricated room module provided in the embodiment of the present application has the aforementioned connection structure between the wall and the support column. The connection between the wall and the support column is reliable and the on-site construction efficiency is high, which reduces the overall construction cost of the prefabricated room module, shortens the construction period of the prefabricated room module, and is conducive to the promotion of the prefabricated room module.

[0082] An embodiment of the present application further provides a building, comprising a plurality of the aforementioned prefabricated room modules, wherein the plurality of prefabricated room modules are connected vertically and / or horizontally.
