The plug-weld holes 7 facilitate plug welding with the embedded parts, effectively transmitting axial force, shear force, and bending moment. Plug welding also results in a more uniform stress distribution, preventing connection failure due to stress concentration and significantly improving the load-bearing capacity of the connection. The steel column 1 has a web reinforcement plate 2 on both sides. The web reinforcement plate 2 has evenly spaced insertion holes, and fixing bolts 3 are inserted into the holes.

To ensure the connection strength between the connecting beam 8 and the secondary beam 9, the pad 16 allows the connecting beam 8 and the secondary beam 9 to form a good fusion, thereby enhancing the load-bearing capacity of the joint. Connecting plates 10 are provided on both sides of the connection between the connecting beam 8 and the secondary beam 9. High-strength bolts 11 are installed inside the connecting plate 10, and high-strength nuts 12 are fitted on the outside of the high-strength bolts 11. A washer 13 is provided on one side of the high-strength nut 12, and the washer 13 is threadedly connected to the high-strength bolt 11. The web reinforcement plate 2 is fixed to the connecting plate 9 by fixing bolts 3 and fixing nuts 4. On both sides of the steel column 1, the reinforcing plate 6 is plug-welded to both sides of the steel column 1 to fix it. Then, the secondary beam 9 is connected to the connecting beam 8 by welding. At the same time, the connecting plate 10 is fixed to both sides of the connection between the connecting beam 8 and the secondary beam 9 by high-strength bolts 11 and washers 13, thereby fixing the connection between the connecting beam 8 and the secondary beam 9. At the same time, the friction is increased by high-strength nuts 12 to enhance the fixing effect. This achieves the purpose of simple connection and good fixing effect, thereby improving the overall load-bearing capacity. Example 2

[0026] Working Principle: In use, the user passes the fixing bolts 3 through the web reinforcement plate 2 and the fixing holes 5, and then fixes the web reinforcement plate 2 to both sides of the steel column 1 with the fixing nuts 4. Plug welding is then performed between the plug welding holes 7 and the embedded parts. Plug welding effectively transmits axial force, shear force, and bending moment, and makes the stress distribution more uniform, avoiding connection failure caused by stress concentration, thus greatly improving the load-bearing capacity of the connection. Subsequently, the reinforcing plates 6 are plug welded to both sides of the steel column 1 for fixation. Then, the secondary beam 9 is connected to the connecting beam 8 by welding, and high-strength bolts 11 are respectively... Passing through the connecting beam 8, secondary beam 9, and connecting plate 10, the connecting plate 10 is fixed to both sides of the connection between the connecting beam 8 and secondary beam 9 using high-strength bolts 11 and washers 13. By welding the washers 16 to the connecting beam 8 and secondary beam 9, the connection strength between the connecting beam 8 and secondary beam 9 can be strengthened. The washers 16 can make the connecting beam 8 and secondary beam 9 form a good fusion, thereby enhancing the load-bearing capacity of the node and fixing the connection between the connecting beam 8 and secondary beam 9. At the same time, the friction is increased by using high-strength nuts 12, which can increase the fixing effect. Thus, the purpose of simple connection and fixing effect is achieved, thereby improving the overall load-bearing capacity.
