[0021] Embodiment: By the specification attached Figure 1-5 It can be seen that the present scheme includes a steel structure column 1 and a node component body 2, wherein plug-in connection components are respectively arranged at the upper and lower ends of the node component body 2, and the plug-in connection components are respectively inserted into the steel structure column 1 and connected to the square flange 3 at the end of the steel structure column 1, and a positioning connection component is arranged on the side wall of the node component body 2, and one end of the positioning connection component is assembled and connected with an "I"-shaped steel beam 4, and the upper and lower ends of the node component body 2 are symmetrically arranged with plug-in connection components, and one end of the plug-in connection component is respectively extended into the upper and lower columns, and assembled and connected with the square flange 3, which has a simple structure and is easy to assemble. At the same time, a positioning connection component is arranged on the side wall of the node component body 2, and the positioning connection component is assembled and connected with the beam by using the positioning connection component, so the structure is stable and the reliability is high;

[0022] In the specific implementation process, the above-mentioned plug-in connection component includes: an assembly groove 5, a limit plug block 6 and a plug-in plate 7, the assembly groove 5 is welded on the node component body 2, and an assembly hole is opened on the assembly groove 5 corresponding to the position of the square flange 3, the limit plug block 6 is welded in the assembly groove 5 and matches the inner diameter of the steel structure column 1, and the plug-in plate 7 is arranged on the limit plug block 6 along a rectangular array. The assembly groove 5 and the square flange 3 are assembled and connected by bolt connectors, wherein a threaded hole is opened on the plug-in plate 7, and a through hole is opened on the side wall of the steel structure column 1 corresponding to the threaded hole. A positioning bolt 8 is inserted in the through hole, and one end of the positioning bolt 8 is connected to the threaded hole. When in use, the steel structure column 1 is inserted into the limiting plug block 6, and the threaded holes on the plug-in plate 7 correspond one to one with the through holes on the side wall of the steel structure column 1. The steel structure column 1 and the plug-in plate 7 are assembled and connected using the positioning bolt 8, thereby improving the connection stability between the node component body 2 and the steel structure column 1. At the same time, the setting of the limiting plug block 6 can effectively avoid the shaking of the steel structure column 1 while ensuring the stability of the connection position, thereby improving the overall structural stability.

[0023] Attached to the instruction manual Figure 1-5 It can be known that in the specific implementation process, the above-mentioned bolt connector includes: a flange gasket 9, a fastening bolt 10 and a limiting nut 11.

Through the setting of the reinforcing plate 16, the structural strength of the slot 13 position can be effectively improved, and the overall structural stability of the node connection position can be improved.
