Scaffolding usage skills

Scaffolding usage skills mainly include the following aspects:

Select appropriate scaffolding accessories: The quality of scaffolding accessories directly affects the stability and safety of the scaffolding. No. 3 steel welded steel pipes with an outer diameter of 48mm and a wall thickness of 3.5mm should be selected, and the surface of the steel pipe should be straight and smooth, without cracks, scars, delamination and other defects. Fasteners should have production licenses, product quality certificates and inspection reports. Old fasteners should be strictly inspected before use, and immediately eliminated when cracks or deformations are found.

Proper installation of scissor braces: Scissor braces are the core structure to ensure the stability and safety of scaffolding. The following points should be noted during installation:

Span and angle: A single scissor brace needs to span 5-7 vertical poles, and the inclination angle should be between 45°-60°.
Continuity: The scissor brace should be set continuously from bottom to top without interruption. The principle of "reinforcement before removal" should be adopted during construction to avoid interruptions.
‌Overlap specification‌: The length of the overlap section should be ≥1 meter, fixed with 3 rotating fasteners, and the end distance should be ≥100mm‌.
‌Fixed position‌: Priority should be given to fastening with the vertical pole, and the second choice should be connected with the small crossbar. It is forbidden to fix it on the suspended pole‌.
‌Safe use of scaffolding‌:

‌Regular inspection and maintenance‌: Ensure that all components meet the quality standards and replace damaged or rusted components in time.
‌Proper use of tools and materials‌: Avoid stacking too heavy objects on the scaffolding to ensure the reasonable placement of construction materials.
‌Comply with operating procedures‌: Construction personnel should receive professional training, be familiar with operating procedures, and ensure construction safety.
By mastering these skills, the efficiency and safety of scaffolding can be effectively improved, and the smooth progress of the construction process can be guaranteed.
