[0048] Please refer to Figures 1 to 4 , an embodiment of the present application provides a steel beam-column connection node for connecting a column 20 and a crossbeam 10.

[0049] The crossbeam 10 is an I-shaped steel, and the crossbeam 10 includes a first beam 11 extending in a first direction D1 and two second beams 12. The cross-section of the first beam 11 is an "I" shape, and the cross-section of the second beam 12 is a "T" shape. The two ends of the first beam 11 in the vertical direction V are respectively fixedly connected to the two second beams 12, and the first direction D1 is parallel to the horizontal plane.

[0050] The steel beam-column connection node includes two connection units 100 arranged in the vertical direction V.

[0051] Each connecting unit 100 includes two connecting components 110 arranged oppositely along the first direction D1. Each connecting component 110 includes a mounting portion 111 and a plugging portion 112. The mounting portion 111 extends along the vertical direction V, and the cross-section of the mounting portion 111 is generally "C"-shaped as a whole. In each connecting unit 100, the two mounting portions 111 are connected by a fastening bolt 120, and an installation cavity 101 for accommodating the column 20 is formed between the two mounting portions 111. The side wall of the installation cavity 101 abuts against the outer surface of the column 20. A plugging portion 112 extending along the first direction D1 is provided on the outer side of each mounting portion 111. A plugging cavity 102 is formed in the plugging portion 112, and the cross-section of the plugging cavity 102 is "T"-shaped. Along the vertical direction V, an opening structure 1021 is provided on one side of the plugging cavity 102 of a connecting unit 100 close to another connecting unit 100.

[0052] The end of the second beam 12 is slidably connected to the side wall of the plugging cavity 102 along the first direction D1, and the mounting portion 111 is connected to the second beam 12 through an assembly bolt 130.

[0053] It should be understood that the outer side of the mounting portion 111 means that when the side wall of the installation cavity 101 abuts against the outer wall of the column 20, in the horizontal direction, the mounting portion 111 is on the side away from the center line of the column 20.

[0054] In this embodiment, the steel structure beam-column connection node includes two connection units 100. Each connection unit 100 is connected to the column 20 and is also connected to one end of a second beam 12 of the crossbeam 10. Specifically, each connection unit 100 includes two connection components 110. Each connection component 110 includes a mounting portion 111 and a plugging portion 112. In each connection unit 100, the two mounting portions 111 are fixedly connected by fastening bolts 120. The side walls of the mounting cavity 101 formed between the two mounting portions 111 (i.e., the inner sides of the two mounting portions 111) are in contact with the column 20, so that the side walls of the mounting cavity 101 are in close contact with the column 20, realizing the fixed connection between each connection unit 100 and the column 20. The cross-sections of the plugging cavity 102 and the second beam 12 are both "T"-shaped and both extend along the first direction D1. The end of each second beam 12 can be adaptively received in a plugging cavity 102, and one end of the second beam 12 can be plugged into the corresponding plugging cavity 102 along its own extension direction. The side walls of the plugging cavity 102 can limit the crossbeam 10 in the second direction D2 and the vertical direction V. In addition, the mounting portion 111 is connected to the second beam 12 by mounting bolts, realizing the fixed connection between the mounting portion 111 and the second beam 12. In this way, the same ends of the two second beams 12 of the crossbeam 10 can be fixedly connected to the two connection units 100 through the plugging portions 112 of the two connection units 100, and the fixed connection between each connection unit 100 and the column 20, that is, the crossbeam 10 is fixedly connected to the column 20 through the two connection units 100.

[0055] When connecting the column 20 and the crossbeam 10 through the steel structure beam-column connection node provided by this embodiment, when the column 20 is connected to each connection unit 100, after the two mounting portions 111 of each connection unit 100 are fixedly connected by the fastening bolts 120, the outer surface of the column 20 can be in contact with the inner sides of the two mounting portions 111 of each connection unit 100. In this way, the assembly connection between the column 20 and the two connection units 100 is completed. When the crossbeam 10 is connected to the connection unit 100, the end of the crossbeam 10 can be preliminarily connected to the two connection units 100 in a plugging manner along the first direction D1, and then the fixed connection between the crossbeam 10 and the connection unit 100 is realized through the assembly bolts 130. It can be seen that through this embodiment, the connection between the column 20 and the crossbeam 10 can be realized. On the premise of ensuring the connection reliability between the crossbeam 10 and the column 20, the structure of this embodiment is simple, the number of parts is relatively small, the installation and connection methods are simple, and the connection process steps between the crossbeam 10 and the column are few. Therefore, the construction efficiency can be improved.

[0056] Figure 5 The structural three-dimensional schematic diagram of the support unit provided by the embodiment of the present application is shown.

[0057] See Figure 1 andFigure 5 , in some embodiments, the steel structure beam-column connection joint further includes two support units 200. The two support units 200 are arranged along the vertical direction V. Each support unit 200 includes a longitudinal shock-proof plate 210 and a spring damper 250. One end of the longitudinal shock-proof plate 210 is fixedly connected to the column 20, and the other end of the longitudinal shock-proof plate 210 is connected to the first end of the spring damper 250. The second end of the spring damper 250 of one support unit 200 is used to abut against the upper end surface of the cross beam 10, and the second end of the spring damper 250 of the other support unit 200 is used to abut against the lower end surface of the cross beam 10. Thus, the two support units 200 can further limit the cross beam 10 in the vertical direction V. Moreover, the spring damper 250 absorbs vibrations, can absorb the vibrations of the cross beam 10 in the vertical direction V, improves the seismic performance of the cross beam 10, reduces damage at the intersection of the cross beam 10 and the column 20 when suffering from vibrations, and improves the safety of the building structure.

[0058] Continue to refer to Figure 5 , in some embodiments, each support unit 200 further includes a rotating handwheel 220, a threaded rod 230, and a guide rod 240. The first end of the elastic damper 250 is connected to one end of the threaded rod 230 through a plain bearing. The middle section of the threaded rod 230 is threadedly connected to the longitudinal shock-proof plate 210. The other end of the threaded rod 230 is connected to the rotating handwheel 220. The longitudinal shock-proof plate 210 is provided with a guide through hole, and a guide rod 240 is inserted into the guide through hole. One end of the guide rod 240 is connected to the elastic damper 250.

[0059] In this embodiment, when the rotating handwheel 220 is rotated, the rotating handwheel 220 drives the threaded rod 230 to move and rotate along the vertical direction V. Since the damper 250 is connected to the longitudinal shock-proof plate 210 through the guide rod 240, the connection threaded rod 230 drives the elastic damper 250 to move along the vertical direction V, thereby adjusting the buffering strength of the elastic damper 250. Among them, the guide rod 240 plays a limiting role, enabling the spring damper 250 to move smoothly in a straight line. Thus, this embodiment can adjust the shock-absorbing ability of the spring damper 250 according to specific implementation requirements, and therefore improves the applicability of the steel structure beam-column connection joint.

[0060] Figure 6 The figure shows a three-dimensional structural schematic diagram of the shock-proof component provided by the embodiment of the present application. Figure 7 The figure shows an assembled sectional three-dimensional view of the heavy damping telescopic rod, the sleeve, and the spring in the embodiment of the present application.

[0061] Refer to Figure 1 , Figure 6 and Figure 7, in some embodiments, the steel structure beam-column connection node further includes a shockproof component 400. The shockproof component 400 includes a transverse shockproof plate 410, a sleeve 420, a spring 430, a damping telescopic rod 440, and an abutting plate 450. The transverse shockproof plate 410 is fixedly connected to the outer surface of the column 20. One end of the transverse shockproof plate 410 is hinged to the sleeve 420. A damping telescopic rod 440 is slidably sleeved in the sleeve 420. A spring 430 is sleeved outside the damping telescopic rod 440. Two ends of the spring 430 are respectively fixedly connected to the damping telescopic rod 440 and the sleeve 420. The end of the damping telescopic rod 440 away from the circular tube is hinged to the abutting plate 450. The plate surface of the abutting plate 450 is used to abut against the side surface of the cross beam 10 along the second direction D2, and the abutting plate 450 is fixedly connected to the side surface of the cross beam 10 along the second direction D2 through a connecting bolt 460.

[0062] In this embodiment, the shockproof component 400 can further limit and fix the cross beam 10 in the second direction D2. In addition, the damping telescopic rod 440 and the spring 430 can absorb the vibration of the cross beam 10 in the second direction D2, improve the seismic performance of the cross beam 10, reduce damage to the intersection part of the cross beam 10 and the column 20 when suffering from vibration, and improve the safety of the building structure.

[0063] Figure 8 The figure shows a three-dimensional structural schematic diagram of the connection adjusting part provided by the embodiment of the present application. Figure 9 The figure shows a connection assembly diagram of the connection adjusting part and the installation part in the embodiment of the present application.

[0064] See Figure 1 、 Figure 8 and Figure 9 , in some embodiments, the steel structure beam-column connection node further includes a connection adjusting part 300. The connection adjusting part 300 includes a first connection part 310 and a second connection part 320. The first connection part 310 is fixedly connected to the installation part 111 of a connection unit 100. The second connection part 320 is fixedly connected to the installation part 111 of another connection unit 100 corresponding in the vertical direction. The first connection part 310 is provided with a first connection hole. The second connection part 320 is provided with a plurality of second connection holes 321. The plurality of second connection holes 321 are arranged along the vertical direction V. The first connection part 310 and the corresponding second connection part 320 are fixedly connected through a first adjusting bolt 330. The first adjusting bolt 330 passes through the first connection hole and one of the second connection holes 321.

[0065] In this embodiment, by means of the connection adjusting member 300, on the one hand, the two connection units 100 can be fixedly connected to each other, and on the other hand, the distance between the two connection units 100 can be adjusted. Specifically, during implementation, according to the dimension of the first beam 11 of the cross beam 10 in the vertical direction, the positions of the two connection units 100 are moved to change the distance between the two connection units 100. The adjusting bolt 330 is passed through the first connection hole and one of the second connection holes 321 to complete the fixation of the positions of the two connection units 100. Because the dimensions of the first beam 11 of the cross beam 10 in the vertical direction are different, the adjusting bolt 330 can be correspondingly passed through different second connection holes 321, enabling the adjustment and fixation of the distance between the two connection units 100. The auxiliary adjustment can be carried out through the scales in the vertical direction of the second connection portion 320, so that the corresponding mounting portions 111 of the two connection units 100 can be adaptively connected to cross beams 10 of different size specifications, improving adaptability.

[0066] Continue to refer to Figure 9 , in some embodiments, the first connection portion 310 is a strip-shaped sleeve, and the second connection portion 320 is a strip-shaped plate. The strip-shaped plate is passed through the corresponding strip-shaped sleeve. Such a connection adjusting member 300 has a simple structure, and the side wall of the strip-shaped sleeve can limit the strip-shaped plate, improving the structural stability of the connection adjusting member 300.

[0067] Refer to Figure 4 and Figure 9 , in some embodiments, each connection assembly 110 further includes two assembly portions 113. The two assembly portions 113 are respectively fixedly connected to both ends of the mounting portion 111 along the second direction D2. The second direction D2 is parallel to the horizontal plane and perpendicular to the first direction D1. In each connection unit 100, the assembly portions 113 connected to the same-side ends of the two mounting portions 111 are fixedly connected by fastening bolts 120. In this way, the fixed connection between the two mounting portions 111 of the same connection unit 100 is realized.

[0068] Figure 10 The figure shows a schematic diagram of the connection and assembly structure between the column 20 and the two connection units 100 provided by the embodiment of the present application.

[0069] Refer to Figure 9 and Figure 10 , in some embodiments, the cross-section of the column 20 is rectangular, the mounting portion 111 is an integrally formed part and its cross-section is in a "C" shape. The mounting portion 111 includes a first plate and two second plates. Both ends of the first plate are respectively fixedly connected to the two second plates.

[0070] Refer to Figure 9 and Figure 10, in some embodiments, the second connecting portion 320 may be provided with scales in the vertical direction, which is convenient for precise adjustment when adjusting the distance between the two connecting units 100.

[0071] Based on the same inventive concept, an embodiment of the present application further provides a steel structure beam-column connection method, which uses the steel structure beam-column connection node provided in any of the above embodiments, including:

[0072] Step 1: Make the side wall of the installation cavity 101 of one connecting unit 100 fit with the outer surface of the column 20, and fixedly connect the two connecting components 110 of the connecting unit 100 through the fastening bolts 120;

[0073] Step 2: Make the side wall of the installation cavity 101 of the other connecting unit 100 fit with the outer peripheral surface of the column 20, and connect the two connecting components 110 of one connecting unit 100 through the fastening bolts 120, and make there be an activity gap between the side wall of the installation cavity 101 and the column 20;

[0074] Step 3: Move the connecting unit 100 in step 2 in the vertical direction V until the vertical distance between the two connecting units 100 reaches the preset distance. After that, tighten the fastening bolts 120 to fixedly connect the two connecting components 110 of the connecting unit 100 in step 2;

[0075] Step 4: Insert the same ends of the two second beams 12 of the cross beam 10 into the installation cavities 101 of the corresponding two installation parts 111 respectively;

[0076] Step 5: Tighten the assembly bolts 130 in step 4 to fixedly connect the two installation parts 111 with one end of the cross beam 10.
