Calculations rules of scaffolding 1
1. General scaffolding outside the building floor by building gross floor area of more than. Building height shall design the outdoor terrace to the eaves height (not including the parapet, roof water tanks, a canopy, height of the stairwell, etc.). Basement (semi-basement) floor area calculation according to the scaffolding.
2. Full scaffolding by building the center line area in square meters ground, not less stack, column occupied land area. Full calculation of scaffold design floor to ceiling height to the bottom (bottom panel) in height shall prevail, when the ceiling height of over 5.2m, 1.0m calculate a higher increase in per layer, but increased when the floor height is less than 0.5m excluding rounding .
3. Full cast reinforced concrete foundation, the width of the belt-shaped base is larger than 3.0m, can be calculated by full house foundation area based scaffold. Share of net wall area is not, nor additional transport channel based outside the area.
4. Elevator installation elevator shaft by a high degree of scaffolding from the bottom of the pit board room count to the end, regardless of ladder large and small in an elevator as a scaffold, Wuhan Ansett mobile computing.
5. Gross floor area can not be integrated by the independent column scaffolding, reinforced concrete walls and vacant single-beam, continuous beam, the single wall decoration scaffolding:
(1) independent of the brick, stone, reinforced concrete column, the external perimeter of the structure by adding 3.6m column multiplied by the area of high column; height of 3.6m or less, apply the single row of scaffolding fixed; 3.6m to apply the appropriate height above The double fixed scaffolding.
(2) place reinforced concrete wall, the wall structure, length multiplied by height in square meters, double height scaffolding to apply the appropriate item.
(3) single-situ reinforced concrete beam or girder, according to the length multiplied by the exterior design beam floor surface (or floor surface) to the top surface of beam height in square meters, double height scaffolding to apply the appropriate projects, and The column is no longer associated with the framework of the calculation of the scaffolding.
6. Height over 3.6m masonry wall decoration can not use the original scaffolding, scaffold decoration can be calculated. Facade scaffolding multiplied by the length of decorative surface height in square meters, with high canopy to apply the appropriate double scaffolding project multiplied by the coefficient 0.3; interior wall and ceiling decorative scaffolding scaffolding calculated by full house.
7. Reinforced concrete, brickwork of the parapet cornice back on the vertical height of more than 1.2m, could be calculated according to the individual fixed scaffolding. Quantities by parapet (or back on) the length of the height multiplied by the square meter eaves height to apply the appropriate scale projects.
8. The level of protective frame, the horizontal projection of the actual ceiling area in square meters.
9. Vertical protective frame, the natural floor to the top layer between the erection of bar height multiplied by the length of the actual erection, in square meters.
10. Scaffolding at the wall in the vertical projection area in square meters.
