Requirements for Scaffolding Erection

First, a specialized construction plan must be prepared before erection, specifying the frame height, 

load conditions, support requirements, arrangement of tie-ins and diagonal bracing, etc. 

Implementation may only commence after the plan has been reviewed and approved. 

The foundation for the scaffold must be level and firm, with no gaps or instability between 

the uprights and the base. Members shall be connected using disc-lock joints, with locking 

pins fully driven into place using a hammer; the amount of settlement must not exceed the limits 

specified in the code to ensure joint reliability. Platforms must be fully decked, guardrails and toe boards 

must be installed on the outer sides, and perimeter safety screens or steel mesh must be erected to 

prevent falls from height and falling objects.

Second, the structural system of the scaffold must be complete, comprising uprights, ledgers, longitudinal 

and transverse diagonal bracing (or dedicated), and tie-ins to form a stable unit. Components from different 

systems must not be mixed arbitrarily. The lift height, bay spacing, and upright diameter must comply with 

codes—for example, the standard type (B-Type) upright diameter is 48.3 mm, and there are clear limits for 

horizontal and longitudinal spacing.

Finally, the structural system must not be altered arbitrarily during use, and dismantling must be carried 

out according to the plan. Regular inspections should be conducted during use to check the condition of 

joints, fittings, frame deformation, and the tightness of connections.
