Connecting angle steel is installed at the four corners of the outer wall of the steel-concrete composite column, and the outer wall of the connecting angle steel is provided with multiple connecting side plates. Multiple side vertical ribs are connected to both sides of the outer wall of the steel-concrete composite column. Multiple beam bottom cover plates are welded to the outer wall of the steel-concrete composite column, and a beam is provided at the top of each beam bottom cover plate.

[0047] Specifically, the support component 303 mainly consists of a support beam 3031 and a support block 3032.

The docking block 3041 on the docking component 304 is connected to the support block 3032, which ensures the stability of the docking block 3041 in the vertical direction. To further enhance the flexibility and adaptability of the structure, a docking groove 3042 is provided, and the docking block 3041 is slidably connected to the docking groove 3042. This structure allows the docking block 3041 to be quickly installed for support, thereby improving the support effect of the structure.

[0048] Working principle: A positioning pin 201 is connected to the upper column 1, allowing the upper column 1 to be positioned and connected through the positioning hole 203 on the lower column 202. During connection, two connecting steel plates 2041 are placed between the upper column 1 and the lower column 202, so that the positioning pin 201 can pass through the connecting hole 2042 on the connecting steel plate 2041 to prevent the connection position from shifting. Then, the fixing plate 2053 is installed on the left side of the fixing screw hole 2051 on the upper column 1 and the lower column 202, so that the fixing screw 2052 passes through the fixing plate 2053 and is threaded into the fixing screw hole 2051 to fix the structure. This structure allows for convenient assembly, improves installation efficiency, avoids structural shifting, and meets the usage requirements.

[0049] Reinforcing holes 301 are made in the connecting steel plate 2041, so that the reinforcing holes 301 can be tightened by the thread of the reinforcing screws 302, thereby fixing the connecting nodes together stably. Since the support beams 3031 are fixedly connected to the upper column 1 and the lower column 202, and the connecting grooves 3042 are made in the support beams 3031, the support blocks 3032 can slide into the inner wall of the connecting grooves 3042 through the connecting blocks 3041 at their bottom. This can strengthen the load-bearing capacity of the nodes after the structure is assembled, and also prevent the nodes from moving, thus meeting the reinforcement requirements.
