Description
Technical Field
[0001] This utility model relates to the field of steel structure buildings, specifically a connection node between a steel frame and a steel frame beam. Background Technology
[0002] In steel structure buildings, the connection nodes between steel columns and steel frame beams are crucial for ensuring the overall stability and load-bearing capacity of the structure. The quality of these connections directly affects the safety and service life of the building. Currently, existing connection methods between steel columns and steel frame beams mainly include fully welded connections, bolt-welded hybrid connections, and fully bolted connections. Fully welded connections achieve fixation by directly welding the beam ends to the column surface. While this method offers high connection strength, it is prone to stress concentration during welding and requires extremely high skill levels from welding technicians. On-site welding operations are significantly affected by environmental factors, making them susceptible to defects such as weld beads and cracks, resulting in high maintenance costs later on.
[0003] Bolted-welded hybrid connections or all-bolted connections require pre-drilled connection holes in the beams and columns, with bolts passing through these holes for fixation. However, this type of connection places stringent requirements on the precision of the holes in the beams and columns. Due to factors such as processing errors, transportation deformation, or on-site installation positioning deviations, it is often difficult to align the holes in the beams and columns, requiring repeated on-site adjustments or even re-drilling. This not only prolongs the construction period and increases labor costs but may also cause component deformation due to forced alignment, reducing the load-bearing capacity of the connection node and making it difficult to adapt to the flexible adjustment requirements in complex construction environments. Therefore, a steel frame beam and steel frame beam connection node is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a connection node between a steel frame and a steel frame beam, thereby solving the problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a connection node between a steel frame and a steel frame beam, comprising: The beam, column, and connecting assembly are welded to the outside of the column near the connection end of the beam. The connecting assembly includes a clamp, an L-shaped frame, and a limiting plate. The clamp is welded to the column, and the L-shaped frame is located at the upper and lower ends of the clamp. An adjusting screw is threadedly installed inside the L-shaped frame, and the adjusting screw is rotatably connected to the limiting plate. The first perforation is equally spaced at one end of the beam closest to the column; The second perforation is equally spaced on the side of the clamping shell near the beam. A bolt is disposed inside the first and second through holes, and a nut is installed on the outside of the bolt; The above structure allows for flexible position adjustment during the connection between the beam and the column. By adjusting the screw to drive the limit plate to move, the height and horizontal position of the beam can be easily adjusted, ensuring precise alignment between the first and second through holes. This reduces the reliance on the accuracy of the initial processing and installation positioning. At the same time, the connection of bolts and nuts enhances the disassembly and connection stability of the joint, reduces quality fluctuations caused by welding operations, and improves construction efficiency and joint safety.
[0006] Preferably, the nut and bolt are connected by a threaded connection. The first through hole is integrally formed with the beam body, and the second through hole is integrally formed with the clamping shell. After the bolt passes through the first through hole and the second through hole, the nut is installed, so that the beam body is connected.
[0007] Preferably, guide shells are provided on both outer sides of the limiting plate, and the guide shells are welded to the limiting plate. The guide shells are used to guide the front and rear sides of the beam for alignment.
[0008] Preferably, a guide plate is provided at one outer end of the limiting plate, and the guide plate is welded to the limiting plate.
[0009] Preferably, a guide groove is provided on the outer side of the L-shaped frame near the guide plate, and the guide groove is integrally formed with the L-shaped frame. The guide groove is used to guide the movement direction of the guide plate.
[0010] Preferably, the guide plate is slidably connected to the guide groove, and the L-shaped frame is welded to the clamping shell.
[0011] Compared with the prior art, this utility model provides a connection node between a steel frame and a steel frame beam, which has the following advantages: This invention achieves precise position adjustment during beam connection by using an adjusting screw in conjunction with a limiting plate. It offers the advantage of quickly aligning the perforations without repeatedly moving the beam during construction, solving the problems of installation difficulties and low efficiency caused by perforation deviations in traditional connection methods. By using bolts passing through the first and second perforations and securing them with nuts, a reliable connection between the beam and column is achieved. This replaces some welding work, reduces welding stress, and solves the problems of stress concentration and quality hazards that easily occur in fully welded connections, improving the stability of the joint connection and construction safety.

[0015] This utility model provides a technical solution: a connection node between a steel frame and a steel beam. (Please refer to...) Figure 1 , Figure 2 and Figure 3 ,include: The beam 1, column 2 and connecting components are welded to the outside of column 2 near the connection end of beam 1. The connecting components include a clamp 4, an L-shaped frame 8 and a limiting plate 10. The clamp 4 is welded to column 2 and the L-shaped frame 8 is located at the upper and lower ends of the clamp 4. The adjusting screw 9 is installed inside the L-shaped frame 8 via a threaded connection, and the adjusting screw 9 is rotatably connected to the limiting plate 10. The first perforation 3 is equally spaced at one end of the beam 1 near the column 2; The second perforation 5 is equally spaced on the side of the clamp 4 near the beam 1; Bolt 6 is located inside the first through hole 3 and the second through hole 5, and nut 7 is installed on the outside of bolt 6.
[0016] Please see Figure 1 and Figure 2 Nut 7 and bolt 6 are connected by threaded engagement. The first through hole 3 is integrally formed with beam 1, and the second through hole 5 is integrally formed with clamp 4. After bolt 6 passes through the first through hole 3 and the second through hole 5, nut 7 is installed, so that beam 1 is connected.
[0017] Please see Figure 1 , Figure 2 and Figure 3 The limiting plate 10 has guide shells 12 on both sides of its outer side, and the guide shells 12 are welded to the limiting plate 10. The guide shells 12 are used to guide the front and rear sides of the beam 1 for alignment.
[0018] Please see Figure 1 , Figure 2 and Figure 3A guide plate 11 is provided at one end of the outer side of the limiting plate 10, and the guide plate 11 is welded to the limiting plate 10.
[0019] Please see Figure 2 and Figure 3 A guide groove 13 is provided on the side of the L-shaped frame 8 near the guide plate 11, and the guide groove 13 is integrally formed with the L-shaped frame 8. The guide groove 13 is used to guide the movement direction of the guide plate 11.
[0020] Please see Figure 1 , Figure 2 and Figure 3 The guide plate 11 is slidably connected to the guide groove 13, and the L-shaped frame 8 is welded to the clamp 4.
[0021] This solution involves welding the clamping shell 4 of the connecting component to the part of the column 2 that needs to be connected to the beam 1. The end of the beam 1 is placed on the upper end of the limiting plate 10. The adjusting screw 9 is rotated, and under the threaded engagement, the adjusting screw 9 and the L-shaped bracket 8 convert the rotational movement of the adjusting screw 9 into the linear movement of the limiting plate 10, thereby lifting the beam 1 and moving it to the required position in the clamping shell 4 until the first through hole 3 and the second through hole 5 are aligned. The bolt 6 is then passed through the first through hole 3 and the second through hole 5, and the nut 7 is installed on the outside of the bolt 6, thus completing the connection between the beam 1 and the column 2.
