[0036] The technical solutions described herein will be further illustrated below with reference to the accompanying drawings and specific embodiments. It is understood that the specific embodiments described herein are merely for illustrative purposes and not for limiting the scope of this document.

[0037] In one embodiment of this application, as Figures 1 to 6 As shown, a wall frame assembly is provided. This wall frame assembly includes two or more vertical joists 1 and two or more horizontal joists 2. In this embodiment, the length direction of the vertical joists 1 is defined as a first direction and denoted as Z. The thickness direction of the wall frame assembly is defined as a second direction and denoted as Y. The first direction and the second direction are perpendicular to each other. Two or more vertical joists 1 are arranged at intervals, and two or more horizontal joists 2 are arranged at intervals along the first direction, with one horizontal joist 2 inserted and fixed to two or more vertical joists 1. Multiple vertical joists 1 and multiple horizontal joists 2 can be arranged parallel to each other. Figure 1 As shown, the technical solution is illustrated using a wall frame assembly consisting of three vertical keels 1 and three horizontal keels 2 as an example.

[0038] like Figure 2 , Figure 3 As shown, the vertical keel 1 includes a first groove 101 and a second groove 102 spaced apart along its length. The first groove 101 and the second groove 102 are arranged in a group. Figure 3 As shown, the projection of the bottom of the first groove 101 in the YZ plane is collinear with the projection of the bottom of the second groove 102 in the YZ plane. Two or more sets of first grooves 101 and second grooves 102 can be provided along the length of the vertical keel 1. One set of first grooves 101 and second grooves 102 can be located at one end of the vertical keel 1 along its length, and another set of first grooves 101 and second grooves 102 can be located at the other end of the vertical keel 1 along its length, to improve the stability of the wall frame assembly structure. Figure 3 As shown, the projection of the groove wall of the first groove 101 onto the YZ plane can be U-shaped. The projection of the groove wall of the second groove 102 onto the YZ plane can also be U-shaped. The shape and size of the first groove 101 and the second groove 102 can be designed to be the same or different. In this embodiment, the technical solution is described by taking the design of the first groove 101 and the second groove 102 as the example.

[0039] The vertical keel 1 also includes a connector 103 located between the first groove 101 and the second groove 102. The first groove 101, the connector 103, and the second groove 102 can be connected sequentially. Alternatively, the first groove 101, multiple connectors 103, and the second groove 102 can be connected sequentially. The projection of the connector 103 in the YZ plane can be rectangular, etc. Figure 3As shown, the portion of the insertion part 103 can be shared with portions of the first groove 101 and the second groove 102. The material of the vertical keel 1 can be steel or the like. The vertical keel 1 can be designed as a single-piece structure, for example, it can be integrally formed using processes such as stamping. Alternatively, the vertical keel 1 can be assembled using processes such as welding.

[0040] The horizontal keel 2 includes a first side plate 201 and a second side plate 202 disposed opposite to each other. The horizontal keel 2 also includes a connecting plate 203 connected to the first side plate 201 and the second side plate 202 respectively. The first side plate 201, the connecting plate 203, and the second side plate 202 can form a U-shape. The horizontal keel 2 can be integrally formed, such as by stamping. A insertion hole 204 is provided on the connecting plate 203, which can be a rectangular through hole, etc. The insertion part 103 and the insertion hole 204 are inserted into each other. After the vertical keel 1 and the horizontal keel 2 are assembled in place, the first side plate 201 is inserted into the bottom of the first groove 101, the second side plate 202 is inserted into the bottom of the second groove 102, and the portion of the insertion part 103 passing through the insertion hole 204 contacts and engages with the side of the connecting plate 203. Overall, the first side plate 201 and the first groove 101, the insertion part 103 and the insertion hole 204, and the second side plate 202 and the second groove 102 constitute a convex-concave mating insertion structure. The portion of the insertion part 103 passing through the insertion hole 204 can be bent in a direction perpendicular to the YZ plane, so that the bent portion of the insertion part 103 contacts and engages with the side of the connecting plate 203, thereby fixing the horizontal keel 2 and the vertical keel 1 together.

[0041] In the actual assembly process, the bottom of the first groove 101 and the second groove 102 can be used as a limiting structure for the horizontal keel 2 to be installed along the second direction (Y direction). After the first side plate 201 and the second side plate 202 are respectively inserted into the bottom of the first groove 101 and the second groove 102, the part of the insertion part 103 that passes through the insertion hole 204 is bent so that the bent part of the insertion part 103 contacts and engages with the side of the connecting plate 203, which also reduces the precision requirements of the bending operation. The vertical keel 1 and the horizontal keel 2 in this wall frame assembly are connected by a plug-in engagement method, which has higher assembly efficiency and effectively reduces the overall manufacturing cost of the product compared to the screw connection method.

[0042] In some exemplary embodiments, such as Figure 3 , Figure 5 As shown, the vertical keel 1 and horizontal keel 2 in the wall frame assembly can be enclosed as follows: Figure 3 , Figure 5The diagram shows multiple receiving cavities 3. Depending on actual needs, sound-absorbing or heat-insulating materials can be filled into the receiving cavities 3 to improve the overall performance of the wall frame assembly. Alternatively, the receiving cavity 3 can be used as a wiring hole to improve the integration of the wall frame assembly and also increase wiring efficiency. Figure 3 , Figure 5 The diagram only illustrates the shapes of two types of receiving cavities 3. The number and shape of the receiving cavities 3 formed by a horizontal keel 2 and a vertical keel 1 along the Z direction are not limited here.

[0043] In some exemplary embodiments, such as Figure 3 , Figure 5 As shown, the insertion part 103 includes two or more insertion ribs 104 spaced apart along the length direction of the vertical keel 1. Figure 3 , Figure 5 Taking a single connector 103 with two connecting ribs 104 as an example. Both or more connecting ribs 104 pass through the connector hole 204, and after passing through the connector hole 204, the connecting ribs 104 contact and engage with the side of the connecting plate 203. The bending directions of two adjacent connecting ribs 104 can be different; for example, one connecting rib 104 may be bent in a direction perpendicular to the YZ plane, while the other connecting rib 104 may be bent in the opposite direction. By configuring a connector 103 as composed of two or more spaced connecting ribs 104, the weight of the vertical keel 1 can be reduced to a certain extent. Furthermore, it facilitates bending operations. Utilizing the interval between two adjacent connecting ribs 104 reduces the precision requirements for bending operations and also reduces the operating force required for bending operations, thereby improving the overall assembly efficiency of the wall frame assembly.

[0044] In some exemplary embodiments, such as Figure 1 As shown, the vertical keel 1 also includes a first fixing part 105 and a second fixing part 106 located at both ends along its length. The vertical keel 1 can be configured as a plate, and the two ends of the plate can be bent to form the first fixing part 105 and the second fixing part 106. Mounting holes (not shown in the figure) can be provided on the first fixing part 105 and the second fixing part 106 respectively, and bolts can be used to fix the two ends of the vertical keel 1 respectively through the mounting holes. For example, the first fixing part 105 can be fixed to the ceiling and the second fixing part 106 can be fixed to the ground using bolts. In the actual installation process, multiple vertical keels 1 can be installed between upper and lower floors first, and then multiple horizontal keels 2 can be fixed to multiple vertical keels 1. Alternatively, multiple vertical keels 1 and multiple horizontal keels 2 can be assembled separately, and then the assembly of multiple vertical keels 1 and multiple horizontal keels 2 can be fixed between upper and lower floors using the first fixing part 105 and the second fixing part 106.

[0045] In some exemplary embodiments, such as Figure 3 , Figure 5As shown, a relief groove 205 is provided on the connecting plate 203. The relief groove 205 is recessed in the extending direction of the first side plate 201 and the second side plate 202. The relief groove 205 does not penetrate the thickness of the connecting plate 203 and can be obtained by stamping in the middle of the connecting plate 203. The insertion hole 204 is provided in the relief groove 205 so that the part of the insertion part 103 passing through the insertion hole 204 is located in the relief groove 205 and does not exceed the other part of the connecting plate 203 except for the relief groove 205. Along the Y direction, the other part of the connecting plate 203 except for the relief groove 205 can extend beyond the edge of the vertical keel 1, forming an effect similar to protruding from the vertical keel 1. This design can ensure the flatness requirement of the wall panel mounting surface and reduce the accuracy requirements for the assembly of both the vertical keel 1 and the horizontal keel 2. Alternatively, along the Y-direction, the portion of the connecting plate 203 other than the clearance groove 205 is flush with the edge of the vertical keel 1, such as... Figure 3 , Figure 5 As shown, this can reduce the overall thickness of the wall frame assembly.

[0046] An allowance groove 205 is provided on the connecting plate 203. On the one hand, this increases the rigidity and strength of the horizontal keel 2. On the other hand, the allowance groove 205 forms a space to accommodate the portion of the plug 103 passing through the plug hole 204. This prevents the portion of the plug 103 passing through the plug hole 204 from protruding beyond the thickness of the entire wall frame assembly, i.e., the dimension along the second direction. It also avoids adverse effects on subsequent operations, such as unevenness when installing wall panels on the horizontal keel 2. When assembling the wall frame assembly into a complete wall unit, the wall panel needs to be fixed to the connecting plate 203 of the horizontal keel 2. The allowance groove 205 eliminates the impact of the plug 103 on the wall panel mounting surface.

[0047] In some exemplary embodiments, such as Figure 5 As shown, the end of the first side plate 201 can be a straight plate. Or, as... Figure 3 As shown, in the YZ plane, the end of the first side plate 201 can be an arc-shaped plate. For example, the cross-sectional shape of the end of the first side plate 201 can be circular or semi-circular. The end of the second side plate 202 can be designed with reference to the end of the first side plate 201, and will not be elaborated further here.

[0048] In some exemplary embodiments, such as Figure 6 As shown, a first insertion slot 107 can be provided at the bottom of the first groove 101, such as... Figure 5 As shown, the first side plate 201 abuts against the bottom of the first insertion groove 107 through the opening of the first insertion groove 107. For example... Figure 6 As shown, a second insertion slot 108 is provided at the bottom of the second groove 102, such as... Figure 5As shown, the second side plate 202 abuts against the bottom of the second insertion groove 108 through the opening of the second insertion groove 108. Abutting means that the two are in contact and fitted. Among them, the first insertion groove 107 and the first side plate 201 are interference-fitted, and the second insertion groove 108 and the second side plate 202 are interference-fitted.

[0049] Alternatively, a first insertion groove 107 can be provided at the end of the first side plate 201, and the bottom of the first groove 101 abuts against the bottom of the first insertion groove 107 through the opening of the first insertion groove 107. That is, by moving the arrangement of the first insertion groove 107 from the bottom of the first groove 101 to the end of the first side plate 201 (closer to the end of the first groove 101), the abutting fit between the first side plate 201 and the first groove 101 can also be achieved. Correspondingly, a second insertion groove 108 can be provided at the end of the second side plate 202, and the bottom of the second groove 102 abuts against the bottom of the second insertion groove 108 through the opening of the second insertion groove 108. The bottom of the first groove 101 and the first insertion groove 107 are interference-fitted, and the bottom of the second groove 102 and the second insertion groove 108 are also interference-fitted.

[0050] The first insertion slot 107 and the second insertion slot 108 can be used to increase the mating dimensions of the vertical keel 1 and the horizontal keel 2, thereby improving the stability of their connection. The interference fit between the first insertion slot 107 and the first side plate 201 (or the interference fit between the bottom of the first groove 101 of the vertical keel 1 and the first side plate 201), and the interference fit between the second insertion slot 108 and the second side plate 202 (or the interference fit between the bottom of the second groove 102 of the vertical keel 1 and the second side plate 202), can improve the connection strength between the vertical keel 1 and the horizontal keel 2, enhance the overall integrity of the wall frame assembly, and improve its overall resistance to deformation.

[0051] In some exemplary embodiments, such as Figure 6As shown, the first insertion slot 107 can be designed as a U-shaped slot, and along the direction perpendicular to the YZ plane, the first insertion slot 107 can penetrate the thickness of the vertical keel 1. Alternatively, along the direction perpendicular to the YZ plane, the first insertion slot 107 does not penetrate the thickness of the vertical keel 1. The end of the first side plate 201 can be designed as a straight plate, and the end of the first side plate 201 is interference-fitted with the groove wall of the first insertion slot 107, that is, the straight plate at the end is interference-fitted with the groove wall of the U-shaped slot. In the design, the opening size of the U-shaped slot (along the Z direction) can be designed to be slightly smaller than the thickness of the straight plate at the end to achieve the interference fit between the two. The first side plate 201 can be designed differently. For example, the first side plate 201 can be roughly divided into two parts. One part does not cooperate with the first insertion groove 107, but is only inserted into the first recess 101. The other part (that is, the end of the first side plate 201) is interference-fitted with the first insertion groove 107 to improve the refinement of the product design and enhance the sense of design sophistication.

[0052] In some exemplary embodiments, such as Figure 3 As shown, the first insertion slot 107 can be designed as an arc-shaped slot, such as a semi-circular slot, a large semi-circular slot, or an irregular arc-shaped slot. The end of the first side plate 201 is designed as an arc-shaped plate, with the arc-shaped plate and the slot wall of the arc-shaped slot having an interference fit. Designing the end of the first side plate 201 as an arc-shaped plate can improve the rigidity and strength of the first side plate 201, and can increase the contact area between the end of the first side plate 201 and the arc-shaped slot, thereby improving the fit strength between the vertical keel 1 and the horizontal keel 2. The second insertion slot 108 can be designed with reference to the first insertion slot 107, and correspondingly, the second side plate 202 can be designed with reference to the first side plate 201, which will not be elaborated further here.

[0053] In some exemplary embodiments, the first groove 101, the first insertion groove 107, the plurality of insertion ribs 104, the second groove 102, and the second insertion groove 108 on the vertical keel 1 can be obtained in one processing step, for example, by one blanking step, so as to reduce the number of manufacturing steps and improve manufacturing efficiency.

[0054] In another embodiment of this application, a method for manufacturing a wall frame assembly is also provided. This manufacturing method is applied to the wall frame assembly described in any of the above embodiments. The manufacturing method includes:

[0055] Fabricating a vertical keel 1. This includes fabricating a first groove 101, a second groove 102, and a connecting portion 103 on the vertical keel 1. The first groove 101, the second groove 102, and the connecting portion 103 can be produced by a single stamping process. Fabricating the vertical keel 1 also includes, based on the above operations, bending both ends of the vertical keel 1 along its length to form a first fixing portion 105 and a second fixing portion 106.

[0056] Fabricate the horizontal keel 2. This includes fabricating a first side plate 201 and a second side plate 202 that are arranged opposite each other, and a connecting plate 203 that connects to the first side plate 201 and the second side plate 202. The first side plate 201, the second side plate 202, and the connecting plate 203 can be obtained through a single stamping process after blanking. The connecting plate 203 is provided with a insertion hole 204 that engages with the insertion part 103. The insertion hole 204 can be obtained in the blanking process. Alternatively, the insertion hole 204 can be obtained by punching after obtaining the first side plate 201, the second side plate 202, and the connecting plate 203.

[0057] The order in which vertical keel 1 and horizontal keel 2 are made can be interchanged. Alternatively, vertical keel 1 and horizontal keel 2 can be made simultaneously.

[0058] Next, assemble the vertical keel 1 and the horizontal keel 2. This includes inserting the first side plate 201 and the second side plate 202 into the first groove 101 and the second groove 102 respectively, so that the insertion part 103 passes through the insertion hole 204, and then the part of the insertion part 103 passing through the insertion hole 204 contacts and engages with the side of the connecting plate 203.

[0059] In some exemplary embodiments, the portion of the plug 103 passing through the plug hole 204 contacts and engages with the side of the connecting plate 203, including: bending the portion of the plug 103 passing through the plug hole 204 so that the portion of the plug 103 passing through the plug hole 204 contacts and engages with the side of the connecting plate 203.
