To meet the operation requirements not exceed the allowable limit of the rod’s bearing capacity, and not exceed the allowable load of the design (270kg/㎡), the scaffolding should take measures to unload the entire structure in sections.
Foundations and foundations:
1. Scaffolding foundation and foundation construction must be handled according to the erection height of the scaffolding and the soil conditions of the erection site.
2. The elevation of the scaffolding base should be 50mm higher than the natural floor. The scaffolding foundation must be flat and the backfill soil must be compacted.
3. A base or pad should be provided at the bottom of each vertical pole (standpipe).
4. The scaffolding must be equipped with vertical and horizontal sweeping poles. The vertical sweeping poles should be fixed on the vertical pole no more than 200mm away from the base epithelium using right-angle fasteners.
5. The horizontal sweeping pole should be fixed to the vertical pole immediately below the longitudinal sweeping pole using right-angle fasteners.
Structural requirements for longitudinal horizontal bars:
1. The longitudinal horizontal pole should be set inside the vertical pole, and its length should not be less than 3 spans.
2. The length of longitudinal horizontal poles should be connected using butt fasteners, or overlapping (overlapping must comply with: the overlapping length should not be less than 1m, and 3 rotating fasteners should be set at equal intervals for fixation, and the end fasteners should be covered The distance from the edge of the plate to the head of the overlapping longitudinal horizontal rod should not be less than 100mm)
3. The width of the skirting board should be no less than 180mm. The skirting boards on the sides should be fixed on the poles on both sides, and the transverse skirting boards should cover the entire width of the scaffolding.
Removal of scaffolding:
1. According to the demolition sequence and measures in the construction organization design, they can be implemented only after approval by the supervisor;
2. The person in charge of the construction unit shall conduct a technical explanation of the demolition;
3. Debris on the scaffolding and obstacles on the ground should be removed;
4. When dismantling scaffolding, it is necessary to mark the work area, set up warning signs or fence the area, and provide guardians to prevent unauthorized persons from entering.
