The invention relates to a pedal applied to a scaffold. The pedal solves the problems that pedals applied to scaffolds are unreasonable in structure and inconvenient to transport in the prior art. According to the pedal applied to the scaffold, provided by the invention, a body comprises a bearing board and at least one inserting board inserted into the bearing board; the body is formed by assembling the bearing board and the inserting board. During transportation, the bearing board and the inserting board can be conveniently separated, so that the pedal is quite convenient to transport, and the use performance of the pedal is optimized; long rods and transverse rods are snapped together, and inserting grooves for accommodating the inserting board and preventing the inserting board from turning over relative to the bearing board are formed in both the long rods located at edges of the bearing board. After the bearing board and the inserting board are assembled, the connecting strength between the bearing board and the inserting board is high, and the anti-bending strength of the pedal is improved, so that the pedal has better stability performance during use.
