Steel structure scaffold

The utility model discloses a steel structure scaffold, which relates to the technical field of scaffolds, solves the problems that the using length of a side supporting vertical frame of the existing steel structure scaffold is fixed and cannot be adjusted, the requirement on the flatness of the supported ground is higher, and the supporting is troublesome, and comprises a supporting positioning rod, and the supporting positioning rod is axially inserted into a vertical rod of the side vertical frame. The leveling assembly can change the using length of a vertical rod of the side vertical frame, so that the frame body assembly can be stably supported on the ground with different flatness without shaking and other phenomena, supporting is convenient and rapid, and meanwhile the leveling assembly has two adjusting and controlling modes, according to the first adjusting mode, the use length of the vertical rod of the side vertical frame is adjusted through the thread action of the rod body of the supporting and
