Both sides of the fixed clamping plates are fixed ears with through - holes. There are two fixed clamping plates, and the two fixed clamping plates respectively clamp both sides of the main steel pipe. The fixed bolts pass through the through - holes of the fixed ears in the fixed clamping plates, and the fixed bolts connect and clamp the two fixed clamping plates to the main steel pipe. The connecting pieces are fixedly connected to the fixed clamping plates, the branch steel pipes are fixedly connected to the connecting pieces, the positioning holes are opened on the main steel pipe, the positioning holes are circular through - holes, and there are at least two positioning holes.

[0007] Furthermore, the positioning protrusion and the fixing clamp are integrally formed.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: The quick-installation splicing structure for square steel pipes disclosed in this utility model uses two "U"-shaped fixing clamps to clamp the square main steel pipe and uses multiple fixing bolts to tighten it. Then, it uses connecting plates to connect with the branch steel pipes, thereby completing the splicing of the steel structure. The main steel pipe and the fixing clamps are respectively provided with positioning holes and positioning protrusions to achieve initial positioning and further improve the fixing effect. In addition, the connecting plates are all connected to the fixing clamps and the branch steel pipes with bolts, which makes installation and disassembly very quick and suitable for use scenarios that require frequent disassembly.
