In addition, the existing construction scaffolds generally need to be moved manually, which affects the construction efficiency. Some construction scaffolds installed with rollers lack fixing devices and are prone to shaking during construction, causing safety hazards. In view of the above problems, the inventor proposes a construction scaffold for solving the above problems. Utility Model Content
