A protection device at the bottom of an attached lifting scaffold is arranged between the bottom of the scaffold body of the attached lifting scaffold and a building structure, and includes a horizontal scaffold floor laid at the bottom of the scaffold body of the attached lifting scaffold, a waste tire nailed on the horizontal scaffold floor through nails, and a turnover scaffold floor provided with one end nailed to the waste tire through nails and the other end leaned against the building structure. The protection device improves the durability of turning points, achieves the effect that the turning point materials need no replacement after the lifting of a climbing rack for a plurality of times; and the adoption of the device betters the coherence of construction procedures, guarantees the construction safety and operability, saves construction time and material, and improves the construction efficiency.
