Description

Technical Field

[0001] This invention relates to a method for realizing a T-shaped connection in lightweight wall panels, belonging to the technical field of lightweight wall panel assembly. Background Technology

[0002] Lightweight walls are a building structural technology that aims to construct wall systems with low weight and high performance by using lightweight materials and innovative design methods. This technology is widely used in modern buildings and offers numerous advantages, such as ease of installation, energy efficiency, environmental friendliness, and high flexibility. Currently, such as Figure 1 As shown, the main framework structure of common lightweight walls is formed by the interconnection of horizontally and vertically arranged light steel keels. The light steel keels in these lightweight wall structures are arranged in the same way. When a T-shaped connection is required (such as at wall intersections), the two lightweight wall sections to be connected will be arranged perpendicularly. Figure 2 and Figure 3 As shown, Figure 2 A structural diagram illustrating a T-connection for this type of lightweight wall. Figure 3 Another structural diagram illustrating T-connections for this type of lightweight wall structure. If directly connected using connectors such as self-tapping screws, then in this case... Figure 2 In this case, the web of the light steel keel located at one end of one of the lightweight wall structures needs to be connected to the waist-height of one side of the light steel keel located in the middle of the other lightweight wall structure. Figure 3 In some cases, the web of a light steel keel located at one end of one lightweight wall needs to be connected to the waist height of one side of two light steel keels located in the middle of another lightweight wall. The contact surfaces in these two cases are not equal. Figure 3 The extra waist height of the two light steel keels in the middle is used to provide a supporting and fixing surface for the subsequent inner sealing plate work, while Figure 2 (This does not take into account the subsequent inner sealing plate work), which leads to the phenomenon that the waist height of the light steel keel is prone to deformation.

[0003] Therefore, in existing technologies, when T-shaped connections are required for such lightweight walls, connectors are often used at the junction of the two sides of the keel to complete the connection, and then tie rods or angle irons are used for reinforcement. Although this method can ensure the stability of the connection between the two sides of the light steel keel, the need to install tie rods or angle irons increases the construction time. Furthermore, the installation of tie rods and angle irons requires the insertion of additional self-tapping screws, which are highly dependent on the operator's construction experience. Improper operation may damage the structure of the light steel keel and affect its strength. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, the present invention provides a method for implementing a T-shaped connection in a lightweight wall.

[0005] The technical solution of the present invention is as follows:

[0006] A method for implementing a T-type connection in a lightweight wall includes the following steps:

[0007] Step 1: Determine the number of the first and second wall panels that need to be connected based on the design drawings;

[0008] Step 2: Determine the structural composition of the first wall panel and the second wall panel; the first wall panel is composed of a first vertical keel and a first horizontal keel set at both ends of the first vertical keel, and the second wall panel is composed of a second vertical keel and a second horizontal keel set at both ends of the second vertical keel. Two second vertical keels are set at the middle position of the second wall panel, and the openings of the two second vertical keels are arranged opposite each other to form a square shape;

[0009] Step 3: Proceed with the molding and shipping of the first and second wall panels. According to the design drawings, mark the positions of each keel on the corresponding wall panel. Then, according to the markings, make a first connecting hole on the web of the first vertical keel located at one end of the first wall panel, and make a second connecting hole on the web of the second vertical keel located at one end of the second wall panel. The second connecting hole can be aligned with the first connecting hole. Then, install the fixing part of the first connecting component in the first vertical keel with the first connecting hole in the first wall panel and in the second vertical keel with the second connecting hole in the second wall panel. Then, connect the first vertical keel and the first horizontal keel according to the design drawings to form the first wall panel, and connect the second vertical keel and the second horizontal keel to form the second wall panel.

[0010] Step 4: On-site installation of the first and second wall panels; transport the manufactured first and second wall panels to the site, then hoist the second wall panel to the required position and fix it according to the design drawings, and then hoist the first wall panel to the required position, so that the web of the first vertical keel with the first connecting hole in the first wall panel abuts against the waist height of the two second vertical keels with the second connecting hole in the second wall panel, and align the first connecting hole with the second connecting hole. At the same time, the two sides of the first wall panel and the corresponding sides of the web of the two second vertical keels forming a U-shape in the second wall panel are on the same horizontal line. Then, by passing the connecting part of the first connecting component through the first connecting hole and the second connecting hole, the T-shaped connection of the first and second wall panels can be completed.

[0011] Furthermore, the second step also includes the following steps: two reinforcing keels are also provided on both sides of the two second vertical keels located in the middle of the second wall panel, and the webs of the two reinforcing keels are closely fitted to the webs of the corresponding second vertical keels.

[0012] Further, the first connecting assembly used in the third and fourth steps includes a first connecting member, a second connecting member, and a first connecting screw. The first and second connecting members are the fixing parts, and the first connecting screw is the connecting part. Both the first and second connecting members are L-shaped. The first connecting member has a first through hole with a diameter adapted to the first connecting screw on both its horizontal and vertical ends. The second connecting member has a first tension hole with an internal thread structure on both its horizontal and vertical ends. The thread structure of each first tension hole is adapted to the thread structure of the first connecting screw. The first tension holes on both sides extend vertically along the inner side of the corresponding end of the second connecting member. The first connecting screw can move through the first connecting hole, the second connecting hole, the first through hole, and be threaded into the first tension hole. When installing the first and second connectors, the first connectors are placed in the first vertical keel with the first connecting holes by taking the corresponding number of first connectors, and the first connecting holes are aligned one by one to temporarily fix the first connectors. The second connectors are placed in the two second vertical keels located at one end of the second wall panel by taking the corresponding number of second connectors, and the first tension holes are aligned one by one to temporarily fix the second connectors. When using the first connecting screw, the first connecting screw is connected to the first connector and the second connector by passing through the first through hole, the first connecting hole, and the second connecting hole in sequence and being threaded into the first tension hole, thus completing the T-shaped connection of the first wall panel and the second wall panel.

[0013] Furthermore, a first bending reinforcing rib is provided at both the lateral and vertical edges of the first connector. The first bending reinforcing ribs on both sides extend along the inner side of the corresponding side end of the first connector, and the ends of the first bending reinforcing ribs on the same side that are close to each other are also fitted together.

[0014] Furthermore, a second bending reinforcing rib is provided at both the lateral and vertical edges of the second connector. The second bending reinforcing ribs on both sides extend along the inner side of the corresponding side end of the second connector, and the ends of the second bending reinforcing ribs on the same side that are close to each other are also fitted together.

[0015] Furthermore, the third step also includes the following steps: According to the design drawings, if it is a cross-shaped connection, a third connecting hole is opened on the waist height of the other side of the two second vertical keels in the middle of the second wall panel, so that the third connecting holes on the two second vertical keels can be set one-to-one with the second connecting holes. Then, the fixing part of the second connecting component is installed in the first vertical keel with the first connecting hole in the first wall panel and in the second vertical keel with the second connecting hole and the third connecting hole in the second wall panel. Then, according to the design drawings, the first vertical keel and the first horizontal keel are connected to form the first wall panel, and the second vertical keel and the second horizontal keel are connected to form the second wall panel.

[0016] Furthermore, the fourth step also includes the following steps: First, according to the design drawings, the second wall panel is hoisted to the required position and fixed. Then, the first wall panel is hoisted to both sides of the second wall panel, so that the web of the first vertical keel with the first connecting hole in one side of the first wall panel abuts against the waist height of the two second vertical keels with the second connecting hole in the second wall panel, and the first connecting hole is aligned with the second connecting hole. On the other side, the web of the first vertical keel with the first connecting hole in the first wall panel abuts against the waist height of the two second vertical keels with the third connecting hole in the second wall panel, and the first connecting hole is aligned with the third connecting hole. At the same time, the two sides of the first wall panels on both sides should be on the same horizontal line as the outer wall of the web of the corresponding side of the two second vertical keels forming a U-shape in the second wall panel. Then, by passing the connecting part of the second connecting component through the first connecting hole and the second connecting hole and the first connecting hole and the third connecting hole, the cross-shaped connection between the first wall panel and the second wall panel can be completed.

[0017] Further, the second connecting assembly used in the third and fourth steps includes a third connecting member, a fourth connecting member, and a second connecting screw. The third and fourth connecting members are the fixing parts, and the second connecting screw is the connecting part. Both the third and fourth connecting members are L-shaped. The third connecting member has a second through hole with a diameter adapted to the second connecting screw on both its horizontal and vertical ends. The fourth connecting member has a second tension hole with an internal thread structure on both its horizontal and vertical ends. The thread structure of each second tension hole is adapted to the thread structure of the second connecting screw. The second tension holes on both sides extend vertically along the inner side of the corresponding end of the fourth connecting member. The second connecting screw can move through the first connecting hole, the second connecting hole, the third connecting hole, the second through hole, and be threaded into the second tension hole. When installing the third and fourth connecting members, by taking the first connecting... A third connector with a corresponding number of holes is placed inside the first vertical keel with the first connecting hole. The third connector is temporarily fixed after the second through hole is aligned with the first connecting hole. A fourth connector with a corresponding number of second and third connecting holes is placed inside the two second vertical keels located in the middle of the second wall panel. The fourth connector is temporarily fixed after the second tension hole is aligned with the corresponding second and third connecting holes. When using the second connecting screw, the second connecting screw is threaded into the second tension hole after passing through the second through hole, the first connecting hole, and the second connecting hole in sequence, or after passing through the second through hole, the first connecting hole, and the third connecting hole in sequence, so that the third connector and the fourth connector can be connected together, thus completing the cross-shaped connection between the first and second wall panels.

[0018] Furthermore, the third connector has a third bending reinforcing rib at both the lateral and vertical edges. The third bending reinforcing ribs on both sides extend along the inner side of the corresponding end of the third connector, and the ends of the third bending reinforcing ribs on the same side that are close to each other are also fitted together.

[0019] Furthermore, a fourth bending reinforcing rib is provided at both the lateral and vertical edges of the fourth connector. The fourth bending reinforcing ribs on both sides extend along the inner side of the corresponding side end of the fourth connector, and the ends of the fourth bending reinforcing ribs on the same side that are close to each other are also fitted together.

[0020] The present invention has the following beneficial effects:

[0021] 1. This invention features a second wall panel specifically designed for T-shaped connections. An opening in the middle of the second wall panel allows for the opposite arrangement of two opposing second vertical keels, forming a U-shape. When the second wall panel is connected to the first wall panel in a T-shape, the second connecting holes on the same side of the two vertical keels in the second wall panel are aligned with the first connecting holes on the web of the first vertical keel in the first wall panel, and then passed through the first connecting assembly. This completes the T-shaped connection between the first and second wall panels. The connection point is at the web of the first vertical keel and the same side of the two second vertical keels. Compared to existing technologies, this invention expands the contact surface during connection, ensuring sufficient structural strength and connection stability at the connection point. This eliminates the need for additional straps or angle irons for reinforcement and avoids the need for additional self-tapping screws. Furthermore, it employs a pre-drilling process, meaning the connecting holes on both the first and second wall panels are pre-drilled during factory production, eliminating the need for on-site drilling. This provides advantages such as structural stability, reduced construction time, and lower operational difficulty.

[0022] 2. The present invention completes the T-shaped connection of the first wall panel and the second wall panel by using a first connecting component. The first connecting component adopts a threaded connection method, which has the advantages of convenient disassembly and reusability compared with the traditional self-tapping screw connection method.

[0023] 3. This invention, by setting reinforcing keels on both sides of the two second vertical keels located in the middle of the second wall panel, and with the corresponding second vertical keels, can form an I-beam-like structure in the middle of the second wall. Compared with the C-shaped keel structure, the I-beam-like structure has better bending and shear strength due to its I-shaped cross-sectional shape. Especially when bearing load, its load-bearing capacity is superior to that of the C-shaped structure. At the same time, the I-beam cross-sectional shape gives it better stability under compression, reducing the possibility of lateral instability. Furthermore, the setting of reinforcing keels provides sufficient support and fixing surface for the panels at the fixing points during subsequent inner panel sealing work, facilitating the sealing work. Compared with the prior art, it has the advantages of structural stability and convenient construction. Attached Figure Description

[0037] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0038] Example 1: Please refer to Figures 1-4 This embodiment provides a method for implementing a T-shaped connection in a lightweight wall, including the following steps:

[0039] Step 1: Determine the quantities of the first wall panel 1 and the second wall panel 2 for T-shaped connection according to the design drawings; that is, according to the actual design drawings, determine the positions that need T-shaped connection, and then make the corresponding quantities of the first wall panel 1 and the second wall panel 2 according to the quantity of the T-shaped connection positions. It should be noted that one first wall panel 1 cooperates with one second wall panel 2 to correspond to one T-shaped connection position.

[0040] Step 2: Determine the structural compositions of the first wall panel 1 and the second wall panel 2; the first wall panel 1 is composed of the first vertical keel 3 and the first horizontal keels 4 provided at both ends of the first vertical keel 3, and the second wall panel 2 is composed of the second vertical keel 5 and the second horizontal keels 6 provided at both ends of the second vertical keel 5. The quantities of the first vertical keel 3, the first horizontal keel 4, the second vertical keel 5, and the second horizontal keel 6 required for the first wall panel 1 and the second wall panel 2 can be determined according to actual needs and are not limited herein. In this embodiment, the first wall panel 1 is composed of three first vertical keels 3 and two first horizontal keels 4, and the second wall panel 2 is composed of four second vertical keels 5 and two second horizontal keels 6. Among them, two second vertical keels 5 are provided at the middle position of the second wall panel 2, and the openings of the two second vertical keels 5 are arranged opposite to each other to form a square shape. At the same time, to ensure the connection stability during subsequent T-shaped connection, in this embodiment, the parameters such as the shape, size, and length of the first vertical keel 3 and the second vertical keel 5 are exactly the same, and the first vertical keel 3 and the second vertical keel 5 are selected as light steel keels with the web length being about twice the waist height length.

[0041] Step 3: Carry out the forming and factory-out work of the first wall panel 1 and the second wall panel 2; according to the set drawing, mark the positions of each keel on the corresponding wall panel, and then, according to the marks, open the first connection holes 7 on the webs of the first vertical keels 3 at one end of the first wall panel 1, and open the second connection holes 8 on the webs of the second vertical keels 5 at one end of the second wall panel 2. The second connection holes 8 can be aligned with the first connection holes 7. The specific quantity and distribution of the first connection holes 7 on the first wall panel 1 can be determined according to the length of the first vertical keel 3, which is not limited here. The second connection holes 8 on the two second vertical keels 5 can be arranged in one-to-one correspondence with the first connection holes 7 on the first vertical keel 3, that is, if there are 4, 6, or 8 first connection holes 7 on the first wall panel 1, the quantity of the second connection holes 8 on each second vertical keel 5 in the middle is 2, 3, or 4. Then, install the fixing parts of the first connection components in the first vertical keels 3 with the first connection holes 7 on the first wall panel 1 and in the second vertical keels 5 with the second connection holes 8 on the second wall panel 2. Then, connect the first vertical keel 3 and the first horizontal keel 4 according to the design drawing to form the first wall panel 1, and connect the second vertical keel 5 and the second horizontal keel 6 to form the second wall panel 2.

[0042] The specific assembly method of the first wall panel 1 and the second wall panel 2 is as follows: Place one of the first horizontal keels 4 on the placement surface with its web height vertically upward, and then place three first vertical keels 3 on this first horizontal keel 4. The placement points are the two ends and the middle position of this first horizontal keel 4. The first vertical keels 3 placed on the two ends of this first horizontal keel 4 have their openings facing each other. Then, place another first horizontal keel 4 on the tops of these three first vertical keels 3 with its web height vertically downward, and then fix the first vertical keels 3 and the first horizontal keel 4 by means of fixed connection such as self-tapping screw connection to complete the assembly of the first wall panel 1.

[0043] Place one of the second horizontal keels 6 on the placement surface with its web height vertically upward, and then place four second vertical keels 5 on this second horizontal keel 6. The placement points are the two ends and the middle position of this second horizontal keel 6. Two second vertical keels 5 are placed at the middle position of this second horizontal keel 6, and the openings of these two second vertical keels 5 face each other to form a square shape. The second vertical keels 5 placed on the two ends of this second horizontal keel 6 have their openings facing each other. Then, place another second horizontal keel 6 on the tops of these four second vertical keels 5 with its web height vertically downward, and then fix the second vertical keels 5 and the second horizontal keel 6 by means of fixed connection such as self-tapping screw connection to complete the assembly of the second wall panel 2.

[0044] Step 4: On-site installation of the first wall panel 1 and the second wall panel 2; transport the manufactured first wall panel 1 and the second wall panel 2 to the site, and then hoist the second wall panel 2 to the required position and fix it according to the design drawings. It can be fixed by driving in anchor bolts or by using external support rods 23 for support and fixation. Then hoist the first wall panel 1 to the required position, so that the web of the first vertical keel 3 with the first connecting hole 7 in the first wall panel 1 abuts against the waist height of the two second vertical keels 5 with the second connecting hole 8 in the second wall panel 2, and align the first connecting hole 7 with its corresponding second connecting hole 8. At the same time, it is also necessary to ensure that the two sides of the first wall panel 1 and the corresponding sides of the web of the two second vertical keels 5 forming a U-shape in the second wall panel 2 are on the same horizontal line. Then, by passing the first connecting component through the first connecting hole 7 and the second connecting hole 8, the T-shaped connection of the first wall panel 1 and the second wall panel 2 can be completed.

[0045] By connecting the first vertical keel 3 with the two second vertical keels 5, the contact surface when the first wall panel 1 and the second wall panel 2 are connected can be expanded, so that the connection position of the first wall panel 1 and the second wall panel 2 has sufficient structural strength and connection stability. Therefore, there is no need to add additional tie rods or angle irons for reinforcement, avoiding the need to drive in additional self-tapping screws, and saving construction time. At the same time, by adopting the pre-drilling process, that is, the connection holes on the first wall panel 1 and the second wall panel 2 are all drilled in the factory production process, there is no need to drill on the construction site, which can further save construction time.

[0046] In this embodiment, the first connecting component used in the third and fourth steps of the above implementation method includes a first connecting member 10, a second connecting member 11, and a first connecting screw 12. The first connecting member 10 and the second connecting member 11 are the fixing parts, and the first connecting screw 12 is the connecting part. Both the first connecting member 10 and the second connecting member 11 are arranged in an L-shape. The first connecting member 10 has a first through hole 13 with a diameter adapted to the first connecting screw 12 on both its horizontal and vertical ends. The second connecting member 11 has a first tension hole 14 with an internal thread structure on both its horizontal and vertical ends. The first tension hole 14 is processed by a common punching and stretching method in the prior art. The thread structure of each first tension hole 14 is adapted to the thread structure of the first connecting screw 12. The first tension holes 14 on both sides extend vertically along the inner side of the corresponding side end of the second connecting member 11. The first connecting screw 12 can move through the first connecting hole 7, the second connecting hole 8, the first through hole 13, and the threaded connecting screw. Connect the first tension hole 14; when installing the first connector 10 and the second connector 11, take the first connector 10 corresponding to the number of first connection holes 7, place the first connector 10 in the first vertical keel 3 with the first connection holes 7, and align the through hole 13 with the first connection hole 7 one by one to temporarily fix the first connector 10 in the first vertical keel 3. Take the second connector 11 corresponding to the number of second connection holes 8, place the second connector 11 in the two second vertical keels 5 located at one end of one side of the second wall panel 2, and align the first tension hole 14 with the second connection hole 8 one by one to temporarily fix the second connector 11 in the second vertical keel 5 to facilitate subsequent installation work. The temporary fixing method for the first connector 10 and the second connector 11 can be the common snap-fit ​​temporary fixing method, or other common temporary fixing methods, which are not limited here. When using the first connecting screw 12 to connect the first wall panel 1 and the second wall panel 2, the first connecting screw 12 passes through the first through hole 13, the first connecting hole 7, and the second connecting hole 8 in sequence and is threaded into the first tension hole 14 so that the first connecting piece 10 and the second connecting piece 11 can be connected together, thus completing the T-shaped connection of the first wall panel 1 and the second wall panel 2.

[0047] During construction, a flat washer m and a spring washer n can be fitted onto the first connecting screw 12. The flat washer m and the spring washer n can prevent the first connecting screw 12 from loosening when it is in the connection position, thereby ensuring the stability of the connection between the first connecting screw 12 and the first wall panel 1 and the second wall panel 2.

[0048] To minimize deformation of the first connector 10, in this embodiment, first bent reinforcing ribs 15 are provided at both the lateral and vertical edges of the first connector 10. The first bent reinforcing ribs 15 extend inward along the corresponding side of the first connector 10, and the ends of the first bent reinforcing ribs 15 on the same side are fitted together. Each first bent reinforcing rib 15 also has an arched center. The first bent reinforcing ribs 15 effectively disperse stress and reduce stress concentration, thereby improving the overall strength, rigidity, and fatigue resistance of the first connector 10. Furthermore, the arched center of the first bent reinforcing rib 15 is less prone to cracking or deformation compared to a straight edge, thus effectively preventing deformation of the first connector 10.

[0049] To minimize deformation of the second connector 11, in this embodiment, second bent reinforcing ribs 16 are provided on both sides of the transverse and vertical ends of the second connector 11. The second bent reinforcing ribs 16 on both sides extend inward along the corresponding side end of the second connector 11, and the ends of the second bent reinforcing ribs 16 on the same side are also fitted together. The middle of each second bent reinforcing rib 16 is also arched. The provision of the second bent reinforcing ribs 16 effectively disperses stress and reduces stress concentration, thereby improving the overall strength, rigidity, and fatigue resistance of the second connector 11. Furthermore, the arched middle portion of the second bent reinforcing rib 16 is less prone to cracking or deformation compared to a straight edge, thus effectively preventing deformation of the second connector 11.

[0050] To further enhance the structural strength at the connection point between the second wall panel 2 and the first wall panel 1, in this embodiment, the second step may further include the following steps: Two reinforcing keels 9 are also provided on both sides of the two second vertical keels 5 located at the middle of the second wall panel 2. The shape, size, length, and other parameters of the reinforcing keels 9 are the same as those of the second vertical keels 5. The webs of the two reinforcing keels 9 are tightly fitted to the webs of the corresponding side second vertical keels 5, and the reinforcing keels 9 can be fixedly connected to the corresponding side second vertical keels 5 using common fixing methods such as bolt connections. With the aforementioned arrangement, the two reinforcing keels 9, in conjunction with the two second vertical keels 5, create two I-beam-like structures in the middle of the second wall. Specifically, one reinforcing keel 9 and one second vertical keel 5 form an I-beam-like structure. Compared to a C-shaped keel structure, the I-beam cross-sectional shape gives this structure better bending and shear strength, especially under load, where its load-bearing capacity is superior. Furthermore, the I-beam cross-sectional shape provides better stability under compression, reducing the possibility of lateral instability. Additionally, the reinforcing keels 9 provide sufficient support and fixing surfaces for the panels at the fixing points during subsequent inner panel installation, facilitating the panel installation process.

[0051] In actual construction, there is a special type of T-connection, namely a cross-shaped connection, which requires first wall panels to be installed on both sides of the second wall panel, and then connecting the first wall panels on both sides to the second wall panel. To accommodate this special T-connection, we propose Embodiment Two.

[0052] Example 2: Please refer to 5 and Figure 6 This embodiment provides a method for implementing a T-shaped connection in a lightweight wall, including the following steps:

[0053] Step 1: Determine the quantity of the first wall panel 1 and the second wall panel 2 used for special T-shaped connections, i.e., cross-shaped connections, according to the design drawings; that is, determine the positions where cross-shaped connections are required based on the actual design drawings, and then produce the corresponding quantity of first wall panel 1 and second wall panel 2 according to the number of cross-shaped connection positions. It should be noted that two first wall panels 1 and one second wall panel 2 correspond to one cross-shaped connection position.

[0054] Step 2: Determine the structural composition of the first wall panel 1 and the second wall panel 2; the first wall panel 1 is composed of the first vertical keel 3 and the first horizontal keels 4 provided at both ends of the first vertical keel 3, and the second wall panel 2 is composed of the second vertical keel 5 and the second horizontal keels 6 provided at both ends of the second vertical keel 5. The quantities of the first vertical keel 3, the first horizontal keel 4, the second vertical keel 5, and the second horizontal keel 6 required for the first wall panel 1 and the second wall panel 2 can be determined according to actual requirements and are not limited herein. In this embodiment, the first wall panel 1 is composed of three first vertical keels 3 and two first horizontal keels 4, and the second wall panel 2 is composed of four second vertical keels 5 and two second horizontal keels 6. Among them, two second vertical keels 5 are provided at the middle position of the second wall panel 2, and the openings of the two second vertical keels 5 are arranged oppositely to form a square shape. At the same time, to ensure the connection stability during subsequent T-shaped connection, in this embodiment, the parameters such as the shape, size, and length of the first vertical keel 3 and the second vertical keel 5 are exactly the same, and the first vertical keel 3 and the second vertical keel 5 are light steel keels with the web length being about twice the waist height length.

[0055] Step 3: Perform the forming and factory-out work of the first wall panel 1 and the second wall panel 2; according to the setting drawing, mark the positions of each keel on the corresponding wall panel.

[0056] The specific assembly method of the first wall panel 1 and the second wall panel 2 is as follows: Place one of the first horizontal keels 4 on the placement surface with its waist height vertically upward. Then place three first vertical keels 3 on this first horizontal keel 4, with the placement points being the two end parts and the middle position of this first horizontal keel 4. The first vertical keels 3 placed on the two end parts of this first horizontal keel 4 are arranged with their openings facing each other. Then, place another first horizontal keel 4 on the tops of these three first vertical keels 3 and make its waist height vertically downward. Then, fix the first vertical keels 3 and the first horizontal keels 4 by using fixing connections such as self-tapping screw connections to complete the assembly of the first wall panel 1.

[0057] Place one of the second horizontal keels 6 on the placement surface with its waist height vertically upward.

The second vertical keels 5 placed on the two end parts of this second horizontal keel 6 are arranged with their openings facing each other. Then, place another second horizontal keel 6 on the tops of these four second vertical keels 5 and make its waist height vertically downward. Then, fix the second vertical keels 5 and the second horizontal keels 6 by using fixing connections such as self-tapping screw connections to complete the assembly of the second wall panel 2.

[0058] Step 4: Carry out the on-site installation work of the first wall panel 1 and the second wall panel 2; transport the manufactured first wall panel 1 and second wall panel 2 to the site. Then, first hoist the second wall panel 2 to the required position and fix it according to the design drawings. It can be fixed by driving in anchor bolts or by using an external support rod 23 for support and fixation. Then, hoist the first wall panel 1 to the two sides of the second wall panel 2. Make the web of the first vertical keel 3 with the first connection hole 7 in one side of the first wall panel 1 abut against the waist height of the two second vertical keels 5 with the second connection hole 8 in the second wall panel 2, and align the first connection hole 7 with the second connection hole 8. Make the web of the first vertical keel 3 with the first connection hole 7 in the other side of the first wall panel 1 abut against the waist height of the two second vertical keels 5 with the third connection hole 17 in the second wall panel 2, and align the first connection hole 7 with the third connection hole 17. At the same time, it is also necessary to make the two side edges of the two first wall panels 1 be on the same horizontal line with the outer walls of the corresponding sides of the two second vertical keels 5 forming a square shape in the second wall panel 2. Then, by passing the connecting part of the second connecting component through the first connection hole 7 and the second connection hole 8 and the first connection hole 7 and the third connection hole 17, the cross-shaped connection of the first wall panel 1 and the second wall panel 2 can be completed.

[0059] In this embodiment, the second connecting component used in the third and fourth steps of the above implementation method includes a third connecting member 18, a fourth connecting member 19, and a second connecting screw 20. The third connecting member 18 and the fourth connecting member 19 are the fixing parts, and the second connecting screw 20 is the connecting part. Both the third connecting member 18 and the fourth connecting member 19 are L-shaped. The third connecting member 18 has a second through hole 21 with a diameter adapted to the second connecting screw 20 on both its horizontal and vertical ends. The fourth connecting member 19 has a second tension hole 22 with an internal thread structure on both its horizontal and vertical ends. The thread structure of each second tension hole 22 is adapted to the thread structure of the second connecting screw 20. The second tension holes 22 on both sides extend vertically along the inner side of the corresponding side end of the fourth connecting member 19. The second connecting screw 20 can move through the first connecting hole 7.

When installing the third connector 18 and the fourth connector 19, the number of third connectors 18 corresponding to the number of first connecting holes 7 is taken, and each third connector 18 is placed inside the first vertical keel 3 with the first connecting hole 7. After aligning the second through hole 21 with the first connecting hole 7, the third connector 18 is temporarily fixed inside the first vertical keel 3. Similarly, the number of fourth connectors 19 corresponding to the number of second connecting holes 8 and third connecting holes 17 is taken, and each fourth connector 19 is placed inside one of the two second vertical keels 5 located in the middle of the second wall panel 2. After aligning the second tension hole 22 with the corresponding second connecting holes 8 and third connecting holes 17, the fourth connector 19 is temporarily fixed inside the second vertical keel 5 to facilitate subsequent installation. The temporary fixing method for the first connector 19 and the second connector 20 can be a common snap-fit ​​connection or other common temporary fixing methods; no restriction is imposed here. When using the second connecting screw 20 to connect the first wall panel 1 and the second wall panel 2, the second connecting screw 20 can be threaded into the second tension hole 22 after passing through the second through hole 21, the first connecting hole 7 and the second connecting hole 8 in sequence, or it can be threaded into the second tension hole 22 after passing through the second through hole 21, the first connecting hole 7 and the third connecting hole 17 in sequence, so that the third connecting piece 18 and the fourth connecting piece 19 can be connected together, thus completing the cross-shaped connection of the first wall panel 1 and the second wall panel 2.

[0060] During construction, a flat washer m and a spring washer n can be fitted onto the second connecting screw 20.

The middle of each third bending reinforcing rib 23 is also arched. The third bending reinforcing ribs 23 effectively disperse stress and reduce stress concentration, thereby improving the overall strength, rigidity, and fatigue resistance of the third connector 18. Furthermore, the arched middle portion of the third bending reinforcing rib 23 is less prone to cracking or deformation compared to a straight edge, thus effectively preventing deformation of the third connector 18.

[0062] To minimize deformation of the fourth connector 19, in this embodiment, fourth bent reinforcing ribs 24 are provided on both sides of the horizontal and vertical ends of the fourth connector 19. The fourth bent reinforcing ribs 24 on both sides extend inward along the corresponding side ends of the fourth connector 19, and the ends of the fourth bent reinforcing ribs 24 on the same side are also fitted together. The middle of each fourth bent reinforcing rib 24 is also arched. The fourth bent reinforcing ribs 24 effectively disperse stress and reduce stress concentration, thereby improving the overall strength, rigidity, and fatigue resistance of the fourth connector 19. Furthermore, the arched middle portion of the fourth bent reinforcing rib 24 is less prone to cracking or deformation compared to a straight edge, thus effectively preventing deformation of the fourth connector 19.

[0063] For ease of use and processing, in this embodiment, the structure of the third connector 16 is substantially the same as that of the first connector 10. The structure of the fourth connector 19 is substantially the same as that of the second connector 11, and the structure of the second connecting screw 20 is substantially the same as that of the first connecting screw 12.
