A frame scaffold has wheels and is often used as a mobile scaffold with the end frame measuring 3 feet or less in width. Designed to be easily moved, they are used for operations such as painting, drywall installation, plastering, and other jobs where workers must frequently change position. Scaffolds can be adapted to stairs, ramps, and other uneven surfaces.
For the design of frame scaffold specification, the strength, rigidity and connection strength of the frame scaffolding and formwork body, it shall adopt the designed value of working load.
For the calculation of ground base bearing capacity and deformation ratio in the limitation status under a normal usage, the standard value of working load, permanent working load and variable working load shall take 1.0 as their division quotient.
When designing the frame scaffolding and formwork bracing, if more than one working loads which are simultaneously imposed on the frame body, a different working load combination shall be formed according to limitation status of bearing capacity and of normal usage and the worst working load effect shall be in one combination.
