Technical Field

[0001] This application relates to the field of steel frame structure technology, and in particular to a detachable interlocking beam-column joint and a steel frame structure. Background Technology

[0002] Beam-column joints are an important component of steel frame structures, as they transfer shear forces and bending moments from floor slabs and beams to columns. Therefore, beam-column joints affect the overall performance of steel frame structures.

[0003] In related technologies, beams and columns are connected by end plates or fishplates and welded to the ends of the beams. The columns are typically hollow-section columns, including circular and square hollow-section columns. It is worth noting that due to the development of single-sided bolt systems (such as blind-hole bolt systems, drilled bolt systems, expansion bolt systems, etc.), beam-column bolted connection nodes using end plates, fishplates, T-plates, or angle steel plates are increasingly being used in steel frames.

[0004] To date, researchers have proposed many variations of bolted connections. For example, one proposed technique involves bolting an upper flange post, lower flange post, post base, I-beam, and connecting plate using at least 74 high-strength bolts. This requires a significant amount of time to tighten and loosen these bolts during assembly, severely impacting the efficiency of assembling and disassembling steel frame structures.

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] See Figures 1 to 8 As shown, one embodiment of this application discloses a detachable interlocking beam-column joint, including a sleeve connector 100, a first connecting column 200, a second connecting column 300, and a beam structure 400.

[0043] Specifically, the sleeve connector 100 includes a sleeve body 110 and a connecting structure 120. The sleeve body 110 has a receiving cavity 111 extending through both ends of its upper end. The connecting structure 120 is disposed within the receiving cavity 111. The outer wall of the sleeve body 110 is provided with at least one first engaging connection portion 130. One end of the first connecting post 200 has four first notches 230. The first connecting post 200 is partially disposed within the receiving cavity 111, and the connecting structure 120 is at least partially located within the first notches 230. Inside; one end of the second connecting post 300 has four second notches 330, the second connecting post 300 passes through the receiving cavity 111, and the connecting structure 120 is at least partially located in the second notches 330; and the number of crossbeam structures 400 is equal to that of the first interlocking connecting portion 130, one end of the crossbeam structure 400 has a second interlocking connecting portion 420, the second interlocking connecting portion 420 is interlocked with the first interlocking connecting portion 130 so that the crossbeam structure 400 is relatively fixed to the sleeve connector 100.

[0044] It should be noted that in the embodiments of this application, both the upper and lower ends of the receiving cavity 111 are open, the first connecting post 200 is disposed in the opening at one end of the receiving cavity 111, and the second connecting post 300 is disposed in the opening at the other end.

[0045] In one possible application scenario, see Figure 9As shown, during assembly, the sleeve connector 100 is installed on the first connecting post 200 having a first notch 230, wherein the first connecting post 200 is at least partially disposed within the receiving cavity 111 of the sleeve connector 100, and the connecting structure 120 is located within the first notch 230; then, one end of the second connecting post 300 having a second notch 330 is placed at the other end of the receiving cavity 111, and the second notch 330 is engaged with the connecting structure 120; then, the second engaging connection portion 420 of the crossbeam structure 400 is engaged with the first engaging connection portion 130 on the outside of the sleeve connector 100, so that the crossbeam structure 400 is fixedly connected to the sleeve connector 100; then, other crossbeam structures 400 are installed until the assembly is completed.

[0046] In the detachable interlocking beam-column joint provided in this embodiment, a connecting structure 120 is provided within the receiving cavity 111 of the sleeve body 110. A first connecting column 200 and a second connecting column 300 are partially disposed within the receiving cavity 111. The first connecting column 200 has a first notch 230 that engages with the connecting structure 120, and the second connecting column 300 has a second notch 330 that engages with the connecting structure 120, facilitating the assembly connection of the first and second connecting columns 200 and the sleeve connector 100. Simultaneously, a first engaging connection portion 130 is provided on the outer wall of the sleeve body 110, which engages with the second engaging connection portion 420 of the beam structure 400, thereby allowing the beam structure 400 to be easily assembled with the sleeve connector 100. In this embodiment, the first connecting column 200, the second connecting column 300, and the beam structure 400 are assembled and connected via the sleeve connector 100, effectively reducing the amount of bolts used and improving assembly efficiency.

[0047] In some embodiments of this application, see Figure 2 As shown, the connecting structure 120 includes a cross plate 121, which is connected to the inner wall of the sleeve body 110. The cross plate 121 is partially disposed within the first notch 230 or the second notch 330. In this way, the cross plate 121 can provide support for the first connecting post 200 or the second connecting post 300, and also helps to improve the structural strength of the sleeve body 110.

[0048] It is understandable that the cross plate 121 that mates with the first notch 230 and the second notch 330 can be the same. In this case, the bottom part of the connecting plate is located inside the first notch 230, and the top part of the connecting plate is located inside the second notch 330. Of course, the cross plate 121 that mates with the first notch 230 and the second notch 330 can also be different. In this case, different cross plates 121 are respectively provided on the inner wall of the sleeve body 110 at the positions corresponding to the first notch 230 and the second notch 330.

[0049] It should be noted that the cross-sectional profile of the sleeve body 110 in this embodiment can be circular, polygonal, or other shapes. Polygons include, but are not limited to, rectangles and squares. Furthermore, the outer profiles of the first connecting post 200 and the second connecting post 300 match the inner wall of the sleeve body 110. Thus, when the first connecting post 200 or the second connecting post 300 is placed within the receiving cavity 111 of the sleeve body 110, the outer wall of the first connecting post 200 or the second connecting post 300 can fit against the inner wall of the receiving cavity 111. This ensures a stable connection between the first connecting post 200 or the second connecting post 300 and the sleeve connector 100, while also simplifying the connection structure between the first connecting post 200 or the second connecting post 300 and the sleeve body 110.

[0050] In some embodiments of this application, the side wall of the sleeve body 110 is further provided with at least one first connecting hole 112, and the first connecting post 200 is provided with a first fastening hole 240 corresponding to the position of the first connecting hole 112. The first connecting hole 112 and the first fastening hole 240 are connected by a fastener 500. In this way, the first connecting post 200 can be fixedly connected to the sleeve body 110, which can enhance the integrity of the structure and also help ensure the stability of the connection between the two.

[0051] In one possible implementation, see Figure 2 and Figure 5 As shown, the sleeve body 110 has a rectangular cross-section, and each of its four sides has a first connecting hole 112. Correspondingly, the first connecting post 200 also has a rectangular cross-section, and each first connecting post 200 has a first fastening hole 240 corresponding to the position of each first connecting hole 112. During assembly, after aligning each first connecting hole 112 with the corresponding first fastening hole 240, the fastener 500 is simultaneously inserted into two first connecting holes 112 and the first fastening hole 240 on the same axis, and the first connecting post 200 and the sleeve body 110 are locked together by the fastener 500, thus fixing them together. In practical applications, the fastener 500 can specifically be a connecting bolt.

[0052] In the above embodiment, the forces from the floor and beams can be transmitted to the first connecting post 200 through the sleeve connector 100 and the connecting bolts.

[0053] In some embodiments of this application, the side wall of the sleeve body 110 is provided with at least one second connecting hole 113, and the second connecting post 300 is provided with a second fastening hole 340 corresponding to the position of the second connecting hole 113. The second connecting hole 113 and the second fastening hole 340 are connected by a fastener 500. In this way, the second connecting post 300 can be fixedly connected to the sleeve body 110 to ensure the stability of the connection.

[0054] In one possible implementation, see Figure 2 and Figure 6 As shown, the sleeve body 110 has a rectangular cross-section, and each of its four sides has a second connecting hole 113. Correspondingly, the second connecting post 300 also has a rectangular cross-section, and each second connecting post 300 has a second fastening hole 340 corresponding to the position of each second connecting hole 113. During assembly, after aligning each second connecting hole 113 with the corresponding second fastening hole 340, the fastener 500 is simultaneously inserted into two second connecting holes 113 and two fastening holes 340 on the same axis, and the second connecting post 300 and sleeve body 110 are locked together using the fastener 500 to secure them. In practical applications, the fastener 500 can specifically be a connecting bolt.

[0055] In the above embodiment, the forces from the floor and beams can be transmitted to the second connecting post through the sleeve connector 100 and the connecting bolts.

[0056] In one possible implementation, see Figure 3 , Figure 5 and Figure 9 As shown, the first connecting post 200 has a rectangular cross-section, and a first notch 230 is provided at the junction of any two adjacent sides of the first connecting post 200. Correspondingly, the sleeve connector 100 includes a sleeve body 110 and a connecting structure 120. The sleeve body 110 also has a rectangular cross-section, and the connecting structure 120 includes a cross plate 121. The cross plate 121 includes a first connecting plate and a second connecting plate arranged in a cross configuration. The first connecting plate is diagonally arranged within the receiving cavity 111, and the second connecting plate is also diagonally arranged within the receiving cavity 111. The first connecting post 200 includes a first side wall 210 and a second side wall 220. A first notch 230 is provided at the intersection of the first side wall 210 and the second side wall 220, and the formation of the first notch 230 at other locations follows the same pattern.

[0057] During assembly, the end of the first connecting post 200 with the first notch 230 is aligned with one of the openings of the receiving cavity 111. At this time, the first notch 230 is located on the extension side of the first connecting plate and the second connecting plate along the axial direction of the sleeve body 110. Then, the sleeve connector 100 is moved along the X direction, which allows the first connecting post 200 to be inserted into the receiving cavity 111, and the first connecting plate or the second connecting plate to be inserted into the first notch 230 at different positions. Here, the axial direction of the sleeve body 110 refers to... Figure 2 The X direction is shown.

[0058] In one possible implementation, see Figure 2 , Figure 6 and Figure 9As shown, the second connecting post 300 has a rectangular cross-section, and a second notch 330 is provided at the junction of any two adjacent sides of the second connecting post 300. Correspondingly, the sleeve connector 100 includes a sleeve body 110 and a connecting structure 120. The sleeve body 110 also has a rectangular cross-section, and the connecting structure 120 includes a cross plate 121. The cross plate 121 includes a first connecting plate and a second connecting plate arranged intersectingly. The first connecting plate is diagonally arranged within the receiving cavity 111, and the second connecting plate is also diagonally arranged within the receiving cavity 111. In this embodiment, the first connecting post 200 includes a first side 310 and a second side 320. A second notch 330 is provided at the intersection of the first side 310 and the second side 320, and the formation of the second notch 330 at other locations follows the same pattern.

[0059] During assembly, the end of the second connecting post 300 with the second notch 330 is aligned with the other opening of the receiving cavity 111. At this time, the second notch 330 is located on the extension line of the first connecting plate and the second connecting plate along the axial direction of the sleeve body 110. Then, the sleeve connector 100 is moved in the X direction, so that the first connecting post 200 can be inserted into the receiving cavity 111, and the first connecting plate or the second connecting plate can be inserted into the second notch 330 at different positions.

[0060] In some embodiments of this application, see Figures 2 to 4 , Figure 7 and Figure 8 The first engagement portion includes at least two first protruding structures 131 spaced apart, with adjacent first protruding structures 131 defining a first engagement groove 132. The second engagement connection portion 420 includes at least one second protruding structure 422, which engages with the first engagement groove 132. The first protruding structures 131 can extend perpendicularly to the X direction or extend along the X direction. When the first protruding structure 131 extends along the X direction, a support structure is required to prevent the second protruding structure 422 from sliding out of the first engagement groove 132. For example, the first engagement groove 132 can be configured as a blind groove, meaning that the end of the first engagement groove 132 near the first connecting post 200 has a support structure that can provide support for the second protruding structure 422.

[0061] In some embodiments of this application, the first engagement portion includes at least one first protruding structure 131, and the second engagement connection portion 420 includes at least two second protruding structures 422. Two adjacent second protruding structures 422 define a second engagement groove 423, and the first protruding structure 131 engages with the second engagement groove 423. The first protruding structure 131 can extend perpendicular to the X direction or extend along the X direction. When the first protruding structure 131 extends along the X direction, a support structure is required to prevent the second protruding structure 422 from sliding out of the first engagement groove 132. For example, the first engagement groove 132 can be configured as a blind groove, that is, the end of the first engagement groove 132 near the first connecting post 200 has a support structure capable of providing support for the second protruding structure 422.

[0062] In this embodiment, see Figures 2 to 4 , Figure 7 and Figure 8 As shown, the first engagement groove 132 gradually decreases in size along the direction away from the sidewall of the sleeve body 110; the first protruding structure 131 extends along the axial direction of the sleeve body 110, and its cross-sectional area gradually decreases along the direction gradually approaching the first connecting post 200. The second protruding structure 422 matches the shape of the first engagement groove 132. Specifically, the first protruding structure 131 includes a first end 1311 and a second end 1312, with the cross-sectional area of ​​the first end 1311 being larger than that of the second end 1312, thus allowing the first engagement groove 132 to gradually decrease in size along the X direction. The design of the second protruding structure 422 matches the first engagement groove 132; that is, the cross-sectional area of ​​the upper end of the second protruding structure 422 is larger than that of the lower end, and its cross-sectional area gradually decreases along the direction away from the sidewall of the sleeve body 110. Thus, when the second protruding structure 422 is inserted into the first engagement groove 132, the second protruding structure 422 can be clamped by the first engagement groove 132, thereby achieving rapid fixation.

[0063] In the above embodiment, the first protruding structure 131 is located within the second engagement groove 423 and is clamped and fixed by the second engagement groove 423. In this way, the beam structure 400 can be quickly connected and fixed to the sleeve connector 100.

[0064] In some embodiments of this application, see Figure 7 and Figure 8As shown, the crossbeam structure 400 includes a crossbeam body 410, and a second interlocking connection part 420 including an end plate 421 and a second protruding structure 422 connected to the end plate 421. One end of the crossbeam body 410 is fixedly connected to the end plate 421. The end plate 421 can be fixedly connected to the crossbeam body 410 by welding, bolting, or other methods. In practical applications, the end plate 421 and the second protruding structure 422 can be fixedly connected to the crossbeam body 410 in a prefabrication plant. This ensures the assembly accuracy of the end plate 421, the second protruding structure 422, and the crossbeam body 410, and also improves subsequent assembly efficiency.

[0065] In one possible implementation, see Figure 7 and Figure 8 As shown, the beam body 410 can be an I-beam or an H-beam. Of course, in some other embodiments, the beam body 410 can also be a profile with other cross-sectional shapes or materials, which is not limited here.

[0066] In some embodiments of this application, the outer wall of the first connecting column 200 matches the inner wall of the sleeve body 110. This effectively controls the gap between the outer wall of the first connecting column 200 and the inner wall of the sleeve body 110, effectively preventing relative swaying and improving the connection stability of the detachable interlocking beam-column joint.

[0067] Similarly, the outer wall of the second connecting post 300 matches the inner wall of the sleeve body 110.

[0068] In application, the structural form of the detachable interlocking beam-column joint in this application embodiment can be diverse.

[0069] For example, in one possible application scenario, see [link to relevant documentation]. Figure 10 In this embodiment, the detachable interlocking beam-column joint is used as an edge column and is typically installed at the edge of a steel frame structure. As shown in the figure, a crossbeam structure 400 is connected to each of the two sides of the outer wall of the sleeve connector 100.

[0070] For example, in another possible application scenario, see Figure 11 In this embodiment, the detachable interlocking beam-column joint is used as a corner column and is typically installed at the corner of a steel frame structure. As shown in the figure, the outer wall of the sleeve connector 100 is connected by two crossbeam structures 400, which are arranged perpendicularly to each other.

[0071] For example, in another possible application scenario, see Figure 12 In this embodiment, the detachable interlocking beam-column joint is used as an inner column and is typically installed inside a steel frame structure. As shown in the figure, a crossbeam structure 400 is connected to all four sides of the outer wall of the sleeve connector 100.

[0072] In one specific embodiment, the detachable interlocking beam-column joint of this embodiment is designed to connect an I-beam and a square hollow column, and mainly includes: a sleeve connector 100, a first connecting column 200, a second connecting column 300, and a crossbeam structure 400. The sleeve connector 100 includes a sleeve body 110 and a cross plate 121. The first interlocking connection part 130 is an external interlocking mortise. The first connecting column 200 and the second connecting column are hollow cross-section columns. The second interlocking connection part 420 is specifically a tenon end plate. The crossbeam body 410 is specifically an I-beam, and the fastener 500 is specifically a single-sided self-tightening bolt.

[0073] In this embodiment, the sleeve connector 100 can provide column-to-column and beam-to-column connections, and up to four I-beams can be connected from different horizontal directions using one sleeve connector 100. The tenon end plate is fixed to the end of the I-beam by welding, and the corners of the first connecting column 200 and the second connecting column are correspondingly fabricated with a first notch 230 and a second notch 330 in the workshop. The interlocking block on the tenon end plate is conical, thereby securely connecting with the external interlocking mortise that matches the sleeve connector 100.

[0074] When assembling the detachable interlocking beam-column joint of this embodiment on site, the sleeve connector 100 can be arranged on the first connecting column 200, and then the second connecting column can be assembled on the sleeve connector 100. The I-beam with tenon end plates is self-guided and self-aligned when assembled with the sleeve connector 100, thus improving assembly efficiency. In addition, the use of single-sided high-strength bolts ensures a firm and effective connection between the first connecting column 200, the second connecting column 300, and the connector, enhancing the structural integrity. In this embodiment, forces from the floor and beams can be transmitted to the first connecting column 200 and the second connecting column 300 through the sleeve connector 100 and the single-sided self-tightening bolts.

[0075] The above embodiments are characterized by facilitating the rapid and safe assembly and disassembly of steel structures, and the disassembled components (such as sleeve connector 100) can be replaced or upgraded and reused.
