Technical requirements for cantilevered scaffolding

Cantilevered scaffolding is a highly dangerous sub-project, with a cantilever height greater than 20 meters. It is a dangerous project exceeding a certain scale, and the cantilever height should not exceed 20 meters.

Technical requirements for cantilevered scaffolding:

1. The distance between the anchor ring and the anchor ring is 200mm;

2. The distance between the anchor ring and the I-beam is 200mm;

3. The cantilevered scaffolding is made of round steel not less than 16 mm;

4. The thickness of the steel pressure plate used for the cantilevered scaffold is not less than 10mm;

5. The ratio of the cantilever anchorage section to the cantilever section is not less than 1.25, and the I-beam should be wedged tightly with wooden squares;

6. The section steel cantilever should adopt biaxially symmetrical I-beam, and the section height should not be less than 160mm;

7. The steel wire rope rings use HPB235 grade steel bars, and the diameter is not less than 20mm;

8. The thickness of the floor slab at the anchorage position should not be less than 120 mm, and reinforcement measures should be taken if it is less than 120 mm.
