First, scaffolding reservation regulations
1. Single-row external ground-type scaffolding should leave scaffolding holes on the wall as the fulcrum of the small crossbar on the wall. Pay attention to the parts where scaffolding holes are not allowed.
2. Adobe walls, earth walls, hollow brick walls, hollow walls, independent brick columns, half brick walls, and 180 thick brick walls.
3. On the brick lintel and in the triangle range of 60 degrees with the lintel, within the range of 3/4 bricks and 1 3/4 bricks on both sides of the door and window openings.
Second, the scaffolding calculation formula
The height of the external wall scaffolding is calculated from the designed outdoor floor to the eaves (or parapet top). The project volume is calculated in square meters according to the length of the outer edge of the external wall (wall buttresses with a protruding wall width greater than 240mm, etc., are expanded and calculated according to the dimensions shown in the figure and included in the length of the external wall) multiplied by the height.
Masonry heights below 15m are calculated as single-row scaffolding; heights above 15m or less than 15m, but the exterior door and window and decoration area exceeds 60% of the exterior wall surface area (or the exterior wall is a cast-in-place concrete wall or lightweight block wall), are calculated as double-row scaffolding; when the building height exceeds 30m, it can be calculated as double-row scaffolding on a steel cantilever platform according to the project conditions.
Independent columns (cast-in-place concrete frame columns) are calculated by adding 3.6m to the outer perimeter of the column diagram structure, multiplied by the designed column height in square meters, and the single-row external scaffolding project is applied. Cast-in-place concrete beams and walls are calculated by the height between the designed outdoor floor or the upper surface of the floor slab and the bottom of the floor slab, multiplied by the net length of the beam and wall in square meters, and the double-row external scaffolding project is applied.
