Scaffolding has a support system to ensure its stability in two directions perpendicular to each other. Before erecting, it must be laid out strictly according to the design requirements. During installation, it is required to add a horizontal tie rod of 48x3.5 steel pipe to fasten it every time a layer of gantry is installed. The support force of the scaffold mainly depends on the overall force of the support frame, and this overall effect should be exerted.
