Positionable butt joint beam column connection

Abstract

This utility model discloses a positionable and dockable beam-column connection structure, relating to the field of beam-column connection technology. It includes a steel column and a steel beam, with steel beams arranged on all four outer sides of the steel column. This positionable and dockable beam-column connection structure allows one end of the steel beam to be inserted between two sets of limiting plates, enabling the top and bottom of the steel beam to move to the inside of a U-shaped frame. At this point, the U-shaped frame and the two sets of limiting plates can limit one end of the steel beam, preventing it from tilting inside the U-shaped frame. Then, the steel beam is pushed towards the steel column. When the steel beam reaches the inclined surface of the trapezoidal locking block, the steel beam can compress the inclined surface of the trapezoidal locking block. An inclined bracing plate is installed between the steel column and the steel beam, forming a triangular stable structure. This effectively improves the lateral stiffness of the structure, reduces inter-story displacement under seismic loads, and helps improve the seismic resistance of the steel column and steel beam.

Description

Technical Field

[0001] This utility model relates to the field of beam-column connection technology, specifically to a beam-column connection structure that can be positioned and connected. Background Technology

[0002] The beam-column connection structure is a key node in a building to achieve the mechanical transfer between horizontal members (beams) and vertical members (columns). Common beams and columns are usually steel structures. The connection methods between beams and columns mainly include welding and bolting. Bolting is more common because it facilitates subsequent disassembly and maintenance.

[0003] In the existing technology, when beams and columns are installed together, multiple sets of threaded holes on the beams and columns need to be aligned with each other before bolts can be inserted into the threaded holes on the beams and columns to complete the installation. In this process, because there are many threaded holes on the beams and columns, it is time-consuming to align the threaded holes on the beams and columns, resulting in low efficiency in the installation of beams and columns together. Utility Model Content

[0004] The purpose of this invention is to provide a beam-column connection structure that can be positioned and connected, so as to solve the problem of low installation efficiency between beams and columns mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positionable and dockable beam-column connection structure, comprising a steel column and a steel beam. The steel column is square, and the steel beams are I-shaped. A U-shaped frame for connecting and supporting the steel beam is welded to the outer side of the steel column near the steel beam. The top and bottom of the U-shaped frame are perforated with first threaded holes for connecting the steel beam. Two sets of limiting plates for limiting the steel beam are welded to the inner side of the U-shaped frame. A connecting block is welded to the outer side of one set of limiting plates. A sliding rod for moving a trapezoidal locking block is slidably connected inside the connecting block. The trapezoidal locking block is connected to the end of the sliding rod. A limiting hole for threaded connection of a threaded knob is provided inside the sliding rod. The threaded knob is threadedly connected to the connecting block near the limiting hole. The size of the limiting hole matches the size of the threaded knob. A return spring for resetting the trapezoidal locking block is connected between the trapezoidal locking block and the connecting block.

[0006] Preferably, a second threaded hole for connecting with the U-shaped frame is provided at the top and bottom of one end of the steel beam, and a triangular slot for positioning the steel beam is provided on the outer surface of the steel beam near the trapezoidal block.

[0007] Preferably, the first threaded hole on the U-shaped frame and the second threaded hole on the steel beam are connected and fixed by a first fastening bolt.

[0008] Preferably, a U-shaped seat is welded to the top surface of the steel beam, and a fixing rod for rotating the diagonal brace is welded to the inner side of the U-shaped seat.

[0009] Preferably, the diagonal brace is rotatably connected to the outside of the fixed rod, and a rotating rod is movably connected to the inner side of the end of the diagonal brace.

[0010] Preferably, both ends of the rotating rod are welded with fixing plates for connecting the connecting plates, and the connecting plates are welded to the ends of the two sets of fixing plates.

[0011] Preferably, the connecting plate has a second fastening bolt for connecting and fixing with the steel column, and the steel column has a matching threaded groove inside near the second fastening bolt.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By using a U-shaped frame and a limiting plate, one end of the steel beam can be inserted into the inside of the U-shaped frame, and the first threaded hole and the second threaded hole can be automatically aligned. Then, the steel beam is positioned by a trapezoidal clip, so that the steel beam and the U-shaped frame can be quickly installed and fixed, thereby improving the installation efficiency between the steel column and the steel beam.

[0013] 2. After the diagonal bracing plates are installed, they are installed at an angle between the steel columns and steel beams. The diagonal bracing plates, steel columns, and steel beams can form a stable triangular structure, which can effectively improve the lateral stiffness of the structure, reduce inter-story displacement under seismic action, and help improve the seismic performance of steel columns and steel beams.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 It is understood that this utility model provides a technical solution: a positioning and docking beam-column connection structure, including a steel column 1 and a steel beam 2. Steel beams 2 are provided on all four sides of the steel column 1. The steel column 1 is square, and the steel beams 2 are I-shaped. A U-shaped frame 3 for connecting and supporting the steel beams 2 is welded to the outer side of the steel column 1 near the steel beams 2. First threaded holes 4 for connecting the steel beams 2 are provided through the top and bottom of the U-shaped frame 3. Two sets of limiting plates 5 for limiting the steel beams 2 are welded to the inner side of the U-shaped frame 3. A connecting block 6 is welded to the outer side of one set of limiting plates 5. The connecting block 6 has an internal sliding connection. A slide rod 7 is provided to move the trapezoidal locking block 9. The trapezoidal locking block 9 is connected to the end of the slide rod 7. A through groove is provided inside a set of limiting plates 5 near the trapezoidal locking block 9. The trapezoidal locking block 9 and the limiting plates 5 form a sliding structure through the through groove. A limiting hole 8 is provided inside the slide rod 7 for threaded connection of the threaded knob 11. The threaded knob 11 is threadedly connected to the inside of the connecting block 6 near the limiting hole 8. The size of the limiting hole 8 matches the size of the threaded knob 11. A reset spring 10 for resetting the trapezoidal locking block 9 is connected between the trapezoidal locking block 9 and the connecting block 6.

[0018] exist Figures 1-4 In the middle: a second threaded hole 12 is provided at the top and bottom of one end of the steel beam 2 for connecting with the U-shaped frame 3, and a triangular slot 13 for positioning the steel beam 2 is provided on the outer surface of the steel beam 2 near the trapezoidal card block 9.

[0019] exist Figure 1 , Figure 2 and Figure 4 In the middle: the first threaded hole 4 on the U-shaped frame 3 and the second threaded hole 12 on the steel beam 2 are connected and fixed by the first fastening bolt 14.

[0020] In practical implementation, traditional beam and column installation requires aligning multiple sets of threaded holes, making the connection and fixing of beams and columns time-consuming and resulting in low installation efficiency. A better approach is to first insert one end of the steel beam 2 between two sets of limiting plates 5, allowing both the top and bottom of the steel beam 2 to move to the inside of the U-shaped frame 3. At this point, the U-shaped frame 3 and the two sets of limiting plates 5 can limit one end of the steel beam 2, preventing it from tilting inside the U-shaped frame 3. Then, push one end of the steel beam 2 towards the steel column 1. When one end of the steel beam 2 moves to the inclined surface of the trapezoidal locking block 9, the steel beam 2 can press against the inclined surface of the trapezoidal locking block 9, causing the trapezoidal locking block 9 to move the sliding rod 7 away from the steel beam 2. Simultaneously, the trapezoidal locking block 9 compresses the return spring 10. When the return spring 10 is compressed to its maximum extent, the steel beam... One end of the steel beam 2 can be moved to the inner surface of the U-shaped frame 3, preventing the steel beam 2 from moving further. At this time, the triangular slot 13 on the steel beam 2 is located outside the trapezoidal block 9, so the outer surface of the steel beam 2 no longer presses against the inclined surface of the trapezoidal block 9, allowing the return spring 10 to perform elastic reset, so that the trapezoidal block 9 can be reset. When the trapezoidal block 9 is reset, its end can be engaged in the triangular slot 13. At this time, the trapezoidal block 9 can position the steel beam 2, making it less likely for the steel beam 2 to loosen. At the same time, the second threaded hole 12 on the steel beam 2 can be moved to the position aligned with the first threaded hole 4 on the U-shaped frame 3. Then, multiple sets of first fastening bolts 14 are respectively inserted into the corresponding first threaded hole 4 and second threaded hole 12, and the first fastening bolts 14 are tightened, thereby fixing one end of the steel beam 2 to the inner side of the U-shaped frame 3, so that the steel beam 2 is connected to the steel column 1.

[0021] See Figures 1-4 It can be seen that, through the U-shaped frame 3 and the limiting plate 5, after one end of the steel beam 2 is inserted into the inner side of the U-shaped frame 3, the first threaded hole 4 and the second threaded hole 12 can be automatically aligned. Then, the steel beam 2 is positioned by the trapezoidal clip 9, so that the steel beam 2 and the U-shaped frame 3 can be quickly installed and fixed, thereby improving the installation efficiency between the steel column 1 and the steel beam 2.

[0022] exist Figure 1 and Figure 5 In the middle: A U-shaped seat 15 is welded to the top surface of the steel beam 2. A fixed rod 16 for rotating the diagonal brace 17 is welded to the inner side of the U-shaped seat 15. The diagonal brace 17 is rotatably connected to the outer side of the fixed rod 16. A rotating rod 18 is movably connected to the inner side of the end of the diagonal brace 17. A fixed plate 19 for connecting the connecting plate 20 is welded to both ends of the rotating rod 18.

[0023] exist Figure 1 and Figure 5In the middle: the connecting plate 20 is welded to the ends of the two sets of fixing plates 19. The connecting plate 20 has a second fastening bolt 21 for connecting and fixing with the steel column 1, and the steel column 1 has a matching threaded groove inside near the second fastening bolt 21.

[0024] In practical implementation, the traditional vertical connection between beams and columns generally has poor seismic resistance, making the main structure of the building susceptible to earthquake damage. After the steel column 1 and steel beam 2 are connected and fixed, one end of the diagonal brace 17 on the steel beam 2 can be pulled towards the steel column 1. When the diagonal brace 17 moves, it can be rotated by the fixing rod 16. When the diagonal brace 17 rotates, it can drive the rotating rod 18 and the connecting plate 20 to rotate and move. When one side of the connecting plate 20 rotates to the outer surface of the steel column 1, the second fastening bolt 21 can be tightened, so that the end of the second fastening bolt 21 can slide into the threaded groove inside the steel column 1, thereby fixing the connecting plate 20 to the outside of the steel column 1. During this process, the position of the connecting plate 20 can be rotated by the rotating rod 18, so that the connecting plate 20 can be installed on the horizontal plate or diagonal block connected to the outside of the steel column 1, thereby improving its practicality of installation.

[0025] See Figure 1 and Figure 5 It can be seen that after the diagonal bracing plate 17 is installed, the diagonal bracing plate 17 is installed in an inclined position between the steel column 1 and the steel beam 2. The diagonal bracing plate 17, the steel column 1 and the steel beam 2 can form a triangular stable structure, thereby effectively improving the lateral stiffness of the structure, reducing the inter-story displacement under seismic action, and helping to improve the seismic performance of the steel column 1 and the steel beam 2.
