[0021] The present application provides a wall, such as Figure 1 and Figure 2As shown, the wall includes a keel chamber 10, an insulation chamber 20, a connecting frame 30 and a wall panel 40 located on one side of the connecting frame 30, the connecting frame 30 includes a base frame 33 and a first bracket 31 located on a first side of the base frame and a second bracket 32 ​​located on a second side of the base frame 33, wherein the keel chamber 10 is defined by the base frame 33 and the first bracket 31, and the interior of the keel chamber 10 is hollow, the insulation chamber 20 includes a first insulation chamber 21 located on a first side of the base frame 33 and a second insulation chamber 22 located on a second side of the base frame 33, the first insulation chamber 21 is defined by the base frame 33, the first bracket 31 and the wall panel 40, the first bracket 31 is connected to the wall panel 40 on a side away from the base frame 33, the second insulation chamber 22 is defined by the base frame 33 and the second bracket 32, and the first insulation chamber 21 and the second insulation chamber 22 are both filled with insulation material pieces composed of insulation material.

[0022] In the wall provided by the present application, both sides of the base frame 33 of the connecting frame 30 are provided with insulation chambers 20, and the first side of the base frame 33 is provided with a hollow keel chamber 10 completely defined by the first bracket 31 of the connecting frame 30, and the hollow keel chamber 10 can play the role of a keel, so that there is no need to set a keel outside the wall, and in addition, the first insulation chamber 21 and the second insulation chamber 22 on both sides of the base frame 33 are filled with insulation material pieces composed of insulation materials, so that the wall has excellent insulation performance. Therefore, the wall provided by the present application does not need an external keel and has good insulation performance.

[0023] The cross section of the keel chamber 10 perpendicular to its own axis is rectangular, and the axis of the keel chamber 10 preferably extends in the vertical direction; in addition, the wall may also have two or more keel chambers 10, and these keel chambers 10 are evenly spaced and distributed in the horizontal direction. However, the present application is not limited thereto, and the cross section of the keel chamber 10 may also be other shapes, such as a circle, a parallelogram, or other irregular shapes, and the axis of the keel chamber 10 is not strictly arranged along the vertical direction, and may also have a certain angle with the vertical direction.

[0024] The cross-section of the first insulation chamber 21 and the second insulation chamber 22 perpendicular to their own axes is rectangular and the axes are arranged in the vertical direction, so as to facilitate filling the insulation material therein, and on the other hand, to facilitate matching with the rectangular keel chamber 10. However, the cross-section of the first insulation chamber 21 and the second insulation chamber 22 can also be of other shapes, and the axes of the first insulation chamber 21 and the second insulation chamber 22 are not limited to extending in the vertical direction, and can be flexibly adjusted according to actual conditions. The insulation material can be rock wool or polyurethane foam material. Based on cost considerations, rock wool is usually selected, but polyurethane foam material can be selected in cases with special needs.

[0025] Since the side wall of the first heat-insulating cavity 21 is not closed, and the wallboard 40 is connected to the first bracket 31 after the heat-insulating material is filled, in order to fix the heat-insulating material in the first heat-insulating cavity 21, as shown in FIG. Figure 1 and Figure 2 As shown, a first connector is provided in the first heat preservation cavity 21, and the first connector can be a screw, a self-tapping screw, a rivet, etc., and preferably, the end of the first connector has a flange to form a stopper, so that the front end of the first connector can pass through the heat preservation material and be connected to the base frame 33, and the stopper formed at the end of the first connector can be pressed against the heat preservation material to ensure the fixing effect of the heat preservation material. And the number of first connectors can be arranged according to the size of the first heat preservation cavity 21.

[0026] exist Figure 1 and Figure 2 In the embodiment, two keel chambers 10 and three first heat preservation chambers 21 are arranged on the first side of the base frame 33, and four second heat preservation chambers 22 are arranged on the second side of the base frame 33. The internal space of the wall is divided into a plurality of separated spaces by the connecting frame 30, thereby ensuring that the wall has sufficient strength. The connecting frame 30 is preferably an integrally formed part, for example, manufactured by a one-time extrusion molding process, so that the connecting frame 30 has good strength as a whole, thereby ensuring the strength of the wall.

[0027] In addition, in order to further improve the strength of the connecting frame, Figure 1 and Figure 2 As shown, the second bracket 32 ​​has a partition plate that separates two adjacent second insulation chambers 22, and the portion of the base frame 33 that defines the keel chamber 10 is connected to the second bracket 32 ​​to separate the partition plate of the two second insulation chambers 22, so that the partition plate forms a reinforcing rib for the keel structure formed by the keel chamber 10, thereby improving the strength of the connecting frame.

[0028] In some cases where the insulation requirements are higher, one or more additional insulation chambers can be added in the direction away from the first insulation chamber 21 of the second insulation chamber 22, and these insulation chambers are defined by the second bracket 32, and are also filled with insulation material pieces made of insulation materials. Therefore, the wall provided by the present application can meet different insulation requirements and has universality.

[0029] The walls provided in this application can be spliced ​​together to form a wall of a larger area, such as Figure 1 and Figure 2As shown, a connecting protrusion 34 is formed at the first end of the connecting member frame in the horizontal direction, and a connecting groove 35 that cooperates with the connecting protrusion 34 is formed at the other end, so that two identical walls can be spliced ​​in the horizontal direction to form a wall with a larger area. The connecting groove 35 and the connecting protrusion 34 can be formed by the first bracket 31 or by the second bracket 32, preferably by the second bracket 32. In order to fix the spliced ​​walls together, a connecting member is passed through the connecting protrusion 34 of one wall and the connecting groove 35 of the wall adjacent to the wall, and the connecting member can be a bolt, a self-tapping screw, a rivet, etc.

[0030] The wall panel 40 of the wall is connected to a side of the first bracket 31 away from the base frame 33, so that the wall panel 40 and the first bracket 31 form a surface contact, and are connected by a second connecting member, which can be a bolt, a self-tapping screw, a rivet, etc., which penetrates the wall panel 40 from the outside and is connected to the board surface of the first bracket 31. In order to ensure the connection strength, multiple second connecting members can be provided for connection, for example, multiple second connecting members are sequentially provided along the axial direction of the keel chamber 10.

[0031] In the embodiment where multiple walls are spliced ​​to form a wall with a larger area, after the splicing is completed, a wall panel 40 matching the area of ​​the entire wall is simultaneously connected to the first brackets 31 of the multiple walls. In addition, the wall panel 40 is located outside the prefabricated house including the wall, and plays a role in protecting the connection frame, and the surface of the wall located inside the house is the second bracket 32.

[0032] In addition, in the spliced ​​embodiment, the two end surfaces of the two first heat-insulating cavities 21 at the two ends are open, so as to contact the first heat-insulating cavities 21 with open end surfaces of the other wall. In the non-spliced ​​embodiment, the end surfaces of the first heat-insulating cavities 21 at the two ends are closed, and the first bracket 31 can form a cavity wall that closes the first heat-insulating cavities 21.

[0033] A second aspect of the present application provides a prefabricated house, which comprises the wall as described above.
