3. Stud set must be equidistant to straight, the longitudinal spacing shall not be more than 1.8 m. Poling horizontal spacing of 1.0 m, poling from metope to 40 cm. Putlog vertical spacing interval) (that is, the scaffold is 1.8 m, the underlying interval shall not be greater than 2 m, small bar pick out the inside and the length of the stud shall not be less than 30 cm and 15 cm respectively. Scaffolding outside every 9 m must establish a bracing, and the Angle of the ground should be controlled in 45 ° to 60 ° between top-down set in a row.
