Calculation rules for scaffolding

External scaffolding
1. The height of the building’s exterior wall scaffolding is calculated from the designed outdoor floor to the cornice (or top of the parapet); the engineering volume is calculated in square meters based on the length of the exterior wall’s outer edge multiplied by the height.
2. If the masonry height is less than 15m, it will be calculated as a single row of scaffolding; if the height is more than 15m or the height is less than 15m, the door, window and decorative area of the exterior wall exceeds more than 60% of the surface area of the exterior wall (or the exterior wall is a cast-in-place concrete wall, light When the building height exceeds 30m, it can be calculated as double-row scaffolding on a profiled steel platform according to the project conditions.
3. For independent columns (cast-in-situ concrete frame columns), add 3.6m to the outer circumference of the structure as shown in the column diagram, multiply by the design column height to calculate in square meters, and apply the single-row exterior scaffolding project. Cast-in-place concrete beams and walls are calculated based on the designed height between the upper surface of the outdoor floor or floor and the bottom of the floor multiplied by the net length of the beam and wall in square meters, and the double-row exterior scaffolding project is applied.
4. The steel pipe frame of the profiled steel platform is calculated in square meters based on the length of the outer edge of the exterior wall multiplied by the design height. The platform overhang width quota has been comprehensively determined, and when used, it is applied separately according to the setting height of the quota items.

Scaffolding
1. For scaffolding on the interior wall of a building, if the designed height from the indoor floor to the lower surface of the roof (or 1/2 of the gable height) is less than 3.6m (non-lightweight block wall), it will be calculated as a single row of scaffolding; the height If it exceeds 3.6m and is less than 6m, it will be calculated as double-row scaffolding.
2. The interior scaffolding is calculated based on the vertical projection area of the wall, and the interior scaffolding project is applied. Various lightweight block walls that cannot leave scaffolding holes in the interior walls are suitable for double-row scaffolding projects.
