[0018] The following description, in conjunction with specific embodiments, provides further details. Figures 1-3 As shown, this embodiment is a steel pipe connection structure for a prefabricated steel trestle, including a U-shaped clamp 1, an mounting block 2, and a locking nut 4. The U-shaped clamp 1 and the mounting block 2 are adapted to be installed on the steel pipe. One end face of the mounting block 2 is provided with a slot 21. Both ends of the U-shaped clamp 1 pass through the mounting block 2, and the locking nut 4 is threaded into the U-shaped clamp 1 and abuts against the mounting block 2. A connecting rod 3 is used to connect the mounting blocks 2 between two steel pipes. Specifically, multiple steel pipes are inserted vertically, and U-shaped clamps 1 and mounting blocks 2 need to be installed at different heights of each steel pipe. During installation, the mounting block 2 is first pressed against the surface of the steel pipe, and then the U-shaped clamp 1 is aligned with the two through holes on the mounting block 2 and inserted. The steel pipe is clamped between the U-shaped clamp 1 and the mounting block 2. The locking nut 4 is fitted into the threaded sections at both ends of the U-shaped clamp 1 and tightened. After the U-shaped clamp 1 is installed at different heights of different steel pipes, multiple connecting rods 3 are used to connect adjacent steel pipes, connecting multiple steel pipes into one unit.
