Description

Technical Field

[0001] This invention relates to a method for achieving corner connections in lightweight walls, belonging to the technical field of lightweight wall 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 arrangement of the light steel keels in these lightweight walls is the same. When corner connections are required (such as at wall corners or wall partitions), such as... Figure 2 As shown, the two lightweight wall panels to be connected are vertically aligned, with their ends close to each other. If they are directly connected using connectors such as self-tapping screws, then the web of the light steel keel at one end of one lightweight wall panel needs to be connected to the corresponding side waist of the two light steel keels at the corresponding end of the other lightweight wall panel. Figure 2 The extended portion of the light steel keel waist is used to provide a supporting and fixing surface for the subsequent inner sealing plate work. Due to issues such as mismatched contact surfaces, the light steel keel waist is prone to deformation.

[0003] Therefore, in existing technologies, when corner connections are required in such lightweight walls, connectors are often used at the junctions of horizontal and vertical light steel keels before reinforcement with tie rods or angle irons. While this method ensures stability at the connection between the horizontal and vertical light steel keels, the need for additional tie rods or angle irons prolongs construction time. Furthermore, the installation of tie rods and angle irons requires the insertion of additional self-tapping screws, which heavily relies on the operator's experience. Improper operation may damage the structure of the light steel keel, affecting its strength. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, this invention provides a method for achieving corner connections in lightweight walls.

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

[0006] A method for achieving corner connections in lightweight walls 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 one end 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 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 holes in the second wall panel, and align the first connecting holes with the second connecting holes one by one. At the same time, the outer side of the first wall panel and the outer wall of the web of the outer second vertical keel forming a U-shape in the second wall panel are on the same horizontal line. Then, by passing the connecting part of the connecting component through the first connecting hole and the second connecting hole, the corner connection of the first and second wall panels can be completed.

[0011] Furthermore, the second step also includes the following steps: a reinforcing keel is provided on one side of one of the two second vertical keels located at one end of the second wall panel, and the web of the reinforcing keel is tightly fitted with the web of the corresponding second vertical keel.

[0012] Further, the connecting assembly used in the fourth step includes a first connector, a second connector, and a connecting screw. The first and second connectors are the fixing parts, and the connecting screw is the connecting part. Both the first and second connectors are L-shaped. The first connector has through holes with diameters adapted to the connecting screw on both its horizontal and vertical ends. The second connector has threaded holes on both its horizontal and vertical ends. The thread structure of each threaded hole is adapted to the thread structure of the connecting screw. The threaded holes on both sides extend vertically along the inner side of the corresponding end of the second connector. The connecting screw can move through the first connecting hole, the second connecting hole, the through hole, and be threaded into the threaded hole. When connecting the first and second connectors... When installing the connectors, take the first connector corresponding to the number of first connecting holes, place the first connector in the first vertical keel with the first connecting holes, and temporarily fix the first connector after aligning the through holes with the first connecting holes. Take the second connector corresponding to the number of second connecting holes, place the second connector in the two second vertical keels located at one end of the second wall panel, and temporarily fix the second connector after aligning the tension holes with the second connecting holes. When using connecting screws, the connecting screws are connected to the first connector and the second connector by passing through the through holes, the first connecting holes, and the second connecting holes in sequence and being threaded into the tension holes, thus completing the corner connection between 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, the middle part of each of the first bent reinforcing ribs is arched.

[0015] 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.

[0016] Furthermore, the middle of each of the second bent reinforcing ribs is arched.

[0017] Furthermore, the connecting screw is also fitted with a flat washer and a spring washer.

[0018] The present invention has the following beneficial effects:

[0019] 1. This invention features a second wall panel specifically designed for corner connections. An opening in the center of the second wall panel allows for the opposite arrangement of two opposing second vertical keels, forming a U-shape. When connecting the second wall panel to the first wall panel at a corner, 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 the connecting assembly is passed through. This completes the corner connection between the first and second wall panels. The connection points are the web of the first vertical keel and the two sides of the second vertical keels at their respective waist heights. 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.

[0020] 2. The present invention completes the T-shaped connection of the first wall panel and the second wall panel by using a connecting component. The 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.

[0021] 3. This invention, by setting a reinforcing keel on one side of one of the two second vertical keels located on one side of the second wall panel, and the reinforcing keel in conjunction with the corresponding second vertical keel, can form an I-beam-like structure at the corresponding end 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 the reinforcing keel 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

[0030] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0031] Example: Please refer to Figures 1-6 This embodiment provides a method for achieving corner connections in lightweight walls, including the following steps:

[0032] Step 1: Determine the quantity of the first wall panel 1 and the second wall panel 2 used for corner connection according to the design drawings; that is, determine the position where corner connection is required according to the actual design drawings, and then make the corresponding quantity of first wall panel 1 and second wall panel 2 according to the number of corner connection positions. It should be noted that one first wall panel 1 is matched with one second wall panel 2 to correspond to one corner connection position.

[0033] Step 2: Determine the structural composition of the first wall panel 1 and the second wall panel 2; the first wall panel 1 consists 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 consists 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 one end 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 corner 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 a web length about twice the waist height length.

[0034] 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, and then, according to the marks, open the first connection holes 7 on the webs of the first vertical keels 3 at one end position 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 position of the second wall panel 2, and 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 and are not limited herein. 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 4, 6, or 8 first connection holes 7 are opened on the first wall panel 1, the quantity of the second connection holes 8 on each of the second vertical keels 5 in the middle is 2, 3, or 4. Then, install the fixing parts of the connection components in the first vertical keels 3 with the first connection holes 7 opened on the first wall panel 1 and in the second vertical keels 5 with the second connection holes 8 opened on the second wall panel 2, and 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.

[0035] 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 at 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 opposite to each other. Then, place another first horizontal keel 4 on the tops of these three first vertical keels 3 with its waist height vertically downward. Then, fix the first vertical keels 3 and the first horizontal keels 4 by using fixing connection methods such as self-tapping screw connection to complete the assembly of the first wall panel 1.

[0036] Place one of the second horizontal keels 6 on the placement surface with its waist height vertically upward. Then place four second vertical keels 5 on this second horizontal keel 6 at the two end parts 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 are arranged opposite to each other to form a square shape. The second vertical keels 5 placed on the two end parts of this second horizontal keel 6 are arranged with their openings opposite to each other. Then, place another second horizontal keel 6 on the tops of these four second vertical keels 5 with its waist height vertically downward. Then, fix the second vertical keels 5 and the second horizontal keels 6 by using fixing connection methods such as self-tapping screw connection to complete the assembly of the second wall panel 2.

[0037] Fourth step: Carry out the on-site installation work of the first wall panel 1 and the second wall panel 2; Transport the made 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 drawing. 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 required position, make the web of the first vertical keel 3 with the first connection hole 7 in the first wall panel 1 abut against the waist heights 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 one by one. At the same time, it is also necessary to make the outer side edge of the first wall panel 1 and the outer wall of the web of the outer second vertical keel 5 forming a square shape in the second wall panel 2 be on the same horizontal line. Then, by passing the connecting part of the connecting component through the first connection hole 7 and the second connection hole 8, the corner connection of the first wall panel 1 and the second wall panel 2 can be completed.

[0038] 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.

[0039] In this embodiment, the connecting components used in the third and fourth steps of the above implementation method include a first connector 10, a second connector 11, and a connecting screw 12. The first connector 10 and the second connector 11 are the fixing parts, and the connecting screw 12 is the connecting part. The number of the first connector 10, the second connector 11, and the connecting screw 12 are appropriately arranged to satisfy one first connector 10 corresponding to one second connector 11 and one connecting screw 12. Both the first connector 10 and the second connector 11 are L-shaped. The first connector 10 has through holes 13 at both its horizontal and vertical ends, with diameters matching those of the connecting screw 12. The second connector 11 has threaded holes 14 at both its horizontal and vertical ends. These threaded holes 14 are manufactured using a common punching and drawing method. The thread structure of each threaded hole 14 is matched to the thread structure of the connecting screw 12. The threaded holes 14 extend vertically along the inner side of the corresponding end of the second connector 11. The diameter of the connecting screw 12 is such that it can move through the first connecting hole 7, the second connecting hole 8, the through hole 13, and be threaded into the threaded hole 14. When installing the first connector 10 and the second connector 11, the first connector 10, corresponding in number to the number of first connecting holes 7, is placed inside the first vertical keel 3 with the first connecting holes 7. The through holes 13 on the first connector 10 are aligned with the first connecting holes 7 one by one, and the first connector 10 is temporarily fixed inside the first vertical keel 3. Similarly, the second connector 11, corresponding in number to the number of second connecting holes 8, is placed inside the two second vertical keels 5 located at one end of one side of the second wall panel 2. The tension holes 14 on the second connector are aligned with the second connecting holes 8 one by one, and the second connector 11 is temporarily fixed inside the second vertical keels 5 to facilitate subsequent installation. The temporary fixing method for the first connector 10 and the second connector 11 can be a common snap-fit ​​connection or other common temporary fixing methods; no limitation is made here. When connecting the first wall panel 1 and the second wall panel 2 using the connecting screw 12, the connecting screw 12 passes through the through hole 13, the first connecting hole 7, and the second connecting hole 8 in sequence and is threaded into the tension hole 14 so that the first connecting piece 10 and the second connecting piece 11 can be connected together, thus completing the corner connection of the first wall panel 1 and the second wall panel 2.

[0040] 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.

[0041] 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.

[0042] 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: A reinforcing keel 9 is also provided on one side of one of the two second vertical keels 5 located at one end of the second wall panel 2. The shape, size, length, and other parameters of the reinforcing keel 9 are the same as those of the second vertical keels 5. The web of the reinforcing keel 9 is tightly fitted to the web of the corresponding second vertical keel 5, and the reinforcing keel 9 can be fixedly connected to the corresponding second vertical keel 5 using common fixing methods such as bolts. Through the aforementioned arrangement, the reinforcing keel 9, in conjunction with the second vertical keel 5, forms an I-beam-like structure at the corresponding end of the second wall. Compared to a 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 loads, its load-bearing capacity is superior to that of a C-shaped structure. Simultaneously, the I-beam cross-sectional shape provides better stability under compression, reducing the possibility of lateral instability. Furthermore, the reinforced keel 9 provides sufficient support and fixing surface for the board at the fixing point during the subsequent inner sealing work, so that the sealing work can proceed smoothly.

[0043] In this embodiment, a flat washer 17 and a spring washer 18 are also fitted on the connecting screw 12. The flat washer 17 and the spring washer 18 can prevent the connecting screw 12 from loosening when it is in the connecting role, so as to ensure the connection stability of the first wall panel 1 and the second wall panel 2.

[0044] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
