General requirements on the formwork support in frame scaffolding system.
The light frames scaffold can be used as formwork support in the real construction projects. Under such circumstances, the data of structure and frame shall be listed out into the construction scheme according to the working load, the support height, and the real usage area.
The protruding length of the adjustable rod brace on the adjustable base shall be less than 200mm. When the protruding length exceeds 200mm, the load bearing of the frame scaffolding shall be rectified according to The Regulations about the adjustable base threaded rod. If the length protrudes about 300mm, it shall multiply 0.9. The adjustment of the formwork height can be done by the adjustable head jack.
It is better to adopt the way of standing tubes delivering the working loads when designing the formwork supporting. When the working load is bore on the flat tubes in the frame scaffolding ,the bearing capacity of the frame scaffolding shall multiply the decrease ratio. And when the load is bore symmetrically on the standing tubes or within the reinforcing tubes, the multiply ratio shall be 0.9. When the working load symmetrically works on the top of the reinforcing tubes, the ratio shall be 0.7.
