The development of a comprehensive scaffolding erection plan should follow these steps and precautions:
1. Working Conditions: The erection plan needs to be approved and thoroughly explained to the workers. All raw materials must be inspected; substandard materials are not permitted. Qualified accessories should be neatly stacked according to type and specifications. The site must be free of water accumulation, and the erection location must be cleared and leveled.
2. Material Selection: Materials should be selected rationally based on the project characteristics and relevant national standards. For example, 48×3.5mm ordinary steel pipes should be used. When used as uprights and diagonal braces, the length should be 4-6 meters, and when used as horizontal braces, approximately 1.3 meters is suitable. Drilling holes in the steel pipes is strictly prohibited. Connecting fasteners must meet material requirements. Scaffold boards should be 50mm thick, with each board weighing no more than 30kg. Commercial concrete with a strength grade of C25 should be used for the foundation.
3. Foundation Treatment: The foundation uses 20cm concrete slab strips. Frozen soil must be cleared and compacted before pouring. After pouring, wooden planks are laid on the slab strips. Two layers of planks are required for the outer scaffolding near the eaves.
4. Erection Requirements: For the scaffolding near the eaves, the middle row should be 1m away from the building. Cross-bracing is added to the first layer of the eaves to reduce the load on the eaves. Double uprights are installed for the outer scaffolding from ±0.00 upwards for 35m. Three rows of scaffolding are erected from the outdoor ground level. The innermost row extends to the bottom of the eaves, the middle row extends 50cm below the roof eaves, and the outermost row extends to the third step of the scaffolding above the eaves.
5. Stress Calculation: The erection dimensions are: vertical spacing of 1.5m, horizontal spacing of 1.05m, vertical spacing of 3.6m, and horizontal spacing of 4.8m. The uniformly distributed load during construction is 3.0 kN/m², with two layers constructed simultaneously, and a total of three layers of scaffold boards laid.
6. Safety Measures: Technical personnel must provide technical and safety briefings to scaffolding erection and site management personnel. Personnel who have not received the briefing are prohibited from participating in the erection work. All materials, including steel pipes, fasteners, and scaffold boards, must be inventoried, inspected, and accepted to ensure they meet design requirements. Debris must be removed from the erection site, and the stability of the slopes must be inspected and addressed.
