[0002] A scaffold is a working platform erected inside and outside a building during the building construction process. An attached scaffold is a temporary structure that provides a working platform and safety protection during building construction. The attached scaffold is fixed to the building structure of a high-rise or super-high-rise building through an attached support structure and can rise layer by layer along with the building construction until the structure is capped.
