External scaffolding calculation method

(1) The height of the scaffolding on the exterior wall of the building is calculated from the design of the outdoor floor to the cornice (or the top of the parapet); the amount of work shall be based on the length of the outer edge of the exterior wall (wall stacks with a protruding wall width greater than 240mm, etc., shall be expanded according to the size shown in the figure) Calculated, incorporated into the exterior wall length), multiplied by the height to calculate in square meters.

(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, but the exterior wall, doors, windows, and decorative areas exceed the surface area of ​​the exterior wall by more than 60% (or the exterior wall is a cast-in-place concrete wall, When the building is more than 30m in height, it can be calculated according to the double-row scaffolding of the steel pick platform according to the engineering situation.

(3) The independent column (cast-in-place concrete frame column) shall be calculated by adding 3.6m to the outer perimeter of the structure as shown in the column, multiplied by the design column height and calculated in square meters, and the single-row outer scaffolding project shall be applied. For cast-in-place concrete beams and walls, the height between the top surface of the designed outdoor floor or floor and the bottom of the floor, multiplied by the net length of the beam and wall, is calculated in square meters, and the double-row outer scaffolding project is applied.

(4) For the steel tube frame of the section steel platform, it is calculated in square meters according to the length of the outer edge of the outer wall multiplied by the design height. The platform’s outer overhang width quota has been comprehensively determined, and it is applied according to the set height of the quota item when using it.
