Because in the latest qualification standards, scaffolding engineering needs to apply for the professional contracting qualification of formwork scaffolding engineering. In the old standard, scaffolding engineering qualification belongs to the qualification category of labor subcontracting enterprises. In the new standard, scaffolding and formwork are subcontracted and merged and divided into professional contracting qualification sequences.
Scaffolding engineering is mainly used for construction personnel to work up and down, or for external safety net enclosure and high-altitude installation components. Scaffolding materials are usually bamboo, wood, steel pipes or synthetic materials. Scaffolding is also used as a template in some projects, and it is also widely used in advertising, municipal administration, traffic bridges, mines and so on.

Matters needing attention in scaffold construction:
1, local deformation caused by scaffold foundation settlement. On the cross section of the double bent frame, a figure of eight or bracing is arranged, and a group of vertical rods are arranged every other row until the deformation zone is discharged. Eight-legged or scissors waste must be placed on a solid and reliable foundation.
2. If the deflection of the cantilever steel beam rooted by the scaffold exceeds the specified value, the rear anchorage point of the cantilever steel beam should be reinforced, supported by steel and fastened with U-shaped bracket to resist the roof. There is a gap between the embedded reinforcing ring and the steel beam, which must be tightened with a horse wedge. Check the wire ropes hanging at the outer ends of steel beams one by one, and tighten them all to ensure uniform stress.
3, scaffolding unloading, traction system local damage, should immediately according to the original scheme of unloading traction method to restore it, and correct the deformation of parts and bars. For example, correct the outward deformation of scaffolding, make a rigid connection, tighten the wire rope at each unloading point to make it stress evenly, and finally let go of the chain.
