[0042] It should be understood that Figures 1 to 4 The steel structure beam-column connecting joint is used for connecting a stand column 20 and a beam 10.

[0043] The beam 10 is an I-shaped steel, and the beam 10 comprises a first beam 11 extending along a first direction D1 and two second beams 12. The first beam 11 has an “I”-shaped cross-section, and the second beam 12 has a “T”-shaped cross-section. The two ends of the first beam 11 along a vertical direction V are fixedly connected with the two second beams 12 respectively, and the first direction D1 is parallel to a horizontal plane.

[0044] The steel structure beam-column connecting joint comprises two connecting units 100 arranged along the vertical direction V.

[0045] Each connecting unit 100 comprises two connecting assemblies 110 oppositely arranged along the first direction D1. Each connecting assembly 110 comprises a mounting portion 111 and a plug-in portion 112. The mounting portion 111 extends along the vertical direction V, and the cross-section of the mounting portion 111 as a whole has a “C” shape. In each connecting unit 100, the two mounting portions 111 are connected through a fastening bolt 120, and a mounting cavity 101 for accommodating the stand column 20 is formed between the two mounting portions 111. The side wall of the mounting cavity 101 abuts against the outer surface of the stand column 20. The outer side of each mounting portion 111 is provided with the plug-in portion 112 extending along the first direction D1. The plug-in portion 112 is provided with a plug-in cavity 102, and the cross-section of the plug-in cavity 102 has a “T” shape. Along the vertical direction V, the plug-in cavity 102 of one connecting unit 100 is provided with an opening structure 1021 on the side close to the other connecting unit 100.

[0046] The end of the second beam 12 is slidingly connected with the side wall of the plug-in cavity 102 along the first direction D1, and the mounting portion 111 is connected with the second beam 12 through an assembly bolt 130.

[0047] It should be understood that the outer side of the mounting portion 111 refers to, when the side wall of the mounting cavity 101 abuts against the outer wall of the stand column 20, the side of the mounting portion 111 away from the center line of the stand column 20 in the horizontal direction.

[0048] In the embodiment, the steel structure beam-column connection joint includes two connection units 100, each of which is connected with the stand column 20 and one end of one second beam 12 of the cross beam 10. Specifically, each connection unit 100 includes two connection assemblies 110, each of which includes a mounting part 111 and a plug-in part 112. In each connection unit 100, the two mounting parts 111 are fixedly connected through the fastening bolt 120, and the side wall of the mounting cavity 101 formed between the two mounting parts 111 (i.e. the inner side of the two mounting parts 111) abuts against the stand column 20, so that the side wall of the mounting cavity 101 tightly abuts against the stand column 20, realizing the fixed connection of each connection unit 100 with the stand column 20. The plug-in cavity 102 and the cross section of the second beam 12 are both "T" shaped and extend along the first direction D1, and the end of each second beam 12 can be fitted into one plug-in cavity 102, and one end of the second beam 12 can be plugged into the corresponding plug-in cavity 102 along the extending direction of the second beam 12, and the side wall of the plug-in cavity 102 can limit the cross beam 10 in the second direction D2 and the vertical direction V. In addition, the mounting part 111 is connected with the second beam 12 through the mounting bolt, realizing the fixed connection between the mounting part 111 and the second beam 12. In this way, the same end of the two second beams 12 of the cross beam 10 can be fixedly connected with the two connection units 100 through the plug-in parts 112 of the two connection units 100, and each connection unit 100 is fixedly connected with the stand column 20, that is, the cross beam 10 is fixedly connected with the stand column 20 through the two connection units 100.

[0049] When the stand column 20 and the cross beam 10 are connected through the steel structure beam-column connection joint provided in the embodiment, when the stand column 20 is connected with each connection unit 100, the outer surface of the stand column 20 can abut against the inner side of the two mounting parts 111 of each connection unit 100 after the two mounting parts 111 of each connection unit 100 are fixedly connected through the fastening bolt 120, so that the assembly connection between the stand column 20 and the two connection units 100 is completed. When the cross beam 10 is connected with the connection unit 100, the end of the cross beam 10 can be preliminarily connected with the two connection units 100 through plug-in in the first direction D1, and then the fixed connection between the cross beam 10 and the connection unit 100 is realized through the assembly bolt 130. It can be seen that the connection between the stand column 20 and the cross beam 10 can be realized through the embodiment, and under the premise of ensuring the reliable connection between the cross beam 10 and the stand column 20, the structure of the embodiment is simple, the number of parts is relatively small, the installation and connection process is simple, and the connection process between the cross beam 10 and the stand column is simple, so that the construction efficiency can be improved.

In this way, the embodiment can adjust the shock absorption capacity of the spring-damping shock absorber 250 according to specific implementation requirements, thereby improving the applicability of the steel structure beam-column connection node.
