For many people who do scaffold engineering, how to make budget is a headache
.
This article will tell you some simple methods
.
You can’t have a try
.
1 calculation rule (1) when calculating the internal and external wall scaffolding, the area occupied by door and window openings, empty ring openings, etc
.
will not be deducted
.
（2） When the height of the same building is different, it shall be calculated according to different heights
.
（3） The project scope of the general contractor does not include the external wall decoration project or the project that the external wall decoration cannot use the main construction scaffold, which can be applied to the main external scaffold or decorative external scaffold project respectively
.
2 external scaffold (I) the height of the external wall scaffold of the building is calculated from the designed outdoor floor to the cornice (or the top of the parapet); the quantities are calculated in square meters by multiplying the length of the external edge line of the external wall (the wall stack protruding from the wall with a width of more than 240mm, etc., which is calculated according to the dimensions shown in the figure and incorporated into the length of the external wall)
.
（2） If the masonry height is less than 15m, it shall be calculated as single row scaffold; if the height is more than 15m or the height is less than 15m, but the exterior wall doors, windows and decorative area is more than 60% of the exterior wall surface area (or the exterior wall is cast-in-place concrete wall or light block wall), it shall be calculated as double row scaffold; if the building height is more than 30m, it shall be calculated as double row scaffold of steel cantilever platform according to the engineering situation
.
（3） Independent column (cast-in-place concrete frame column) shall be calculated in square meters according to the perimeter of the structure shown in the column diagram plus 3.6m multiplied by the design column height, and the single row external scaffold project shall be applied
.
For cast-in-place concrete beams and walls, the height between the designed outdoor floor or the upper surface of the floor and the bottom of the floor shall be multiplied by the net length of the beam and wall in square meters, and the double row external scaffold project shall be applied
.
（4） The steel pipe frame of the steel platform is calculated in square meters according to the length of the outer wall sideline multiplied by the design height
.
The norm of platform overhanging width has been determined comprehensively, and is applied separately according to the setting height of norm items
.
3-li scaffold (I) for the scaffold of the internal wall of a building, when the height from the designed indoor floor to the lower surface of the roof (or 1 / 2 of the height of the gable) is less than 3.6m (non light block wall), it shall be calculated as a single row of scaffold; when the height is more than 3.6m and less than 6m, it shall be calculated as a double row of scaffold
.
（2） The inner scaffold is calculated according to the vertical projection area of the wall, and the inner scaffold project is applied
.
All kinds of light block walls with scaffold holes on the inner wall can not be applied with double row scaffold project
.
4 scaffold (1) if the original masonry scaffold can not be used for interior wall decoration with height over 3.6m, the decorative scaffold can be calculated according to the calculation rules of interior scaffold
.
Decorative scaffold is calculated by multiplying double row scaffold by 0.3 coefficient
.
（2） When the decorative surface of indoor ceiling is more than 3.6m away from the designed indoor floor, the full scaffold can be calculated
.
The full scaffold is calculated according to the indoor net area
.
When its height is between 3.61 ~ 5.2m, the basic floor is calculated
.
When it is more than 5.2m, every 1.2m increase is calculated as one additional layer, and those less than 0.6m are not counted
.
The additional layer is calculated according to the following formula: the additional layer of full hall scaffold = [indoor net height – 5.2 (m)] / 1.2 (m) (III) when the external wall decoration can not use the main scaffold for construction, the external wall decoration scaffold can be calculated
.
The external wall decoration scaffold shall be calculated according to the designed external wall decoration area, and the corresponding quota items shall be applied
.
The external wall decoration scaffold shall not be calculated for the external wall paint and brush
.
（4） After the full scaffold is calculated according to the regulations, the scaffold is no longer calculated for the interior wall decoration project
.
5
.
Other scaffolds (I) wall scaffolds shall be calculated in square meters according to the masonry height from the outdoor natural floor to the top of the wall multiplied by the length
.
The corresponding items of single row scaffold shall be used for the wall scaffold
.
（2） When the masonry height of the stone wall is more than 1.0 mm, it shall be calculated in square meters according to the design masonry height multiplied by the length, and the double row scaffold project shall be applied
.
（3） The horizontal protective frame is calculated in square meters according to the horizontal projected area of the actual planking
.
（4） The vertical protective frame shall be calculated in square meters according to the erection height between the natural floor and the top cross bar multiplied by the actual erection length
.
（5） The scaffold shall be erected according to the length and the number of layers, and calculated by the extension meter
.
（6） The suspended scaffold is calculated in square meters according to the horizontal projection area
.
（7） Chimney scaffolds are calculated according to different erection heights
.
For the concrete chimney and silo constructed with sliding formwork, the scaffold shall not be calculated separately
.
（8） The scaffold of elevator shaft is calculated by single hole
.
（9） Different heights of ramps are calculated by seat
.
（10） For the construction of warehouse scaffold, regardless of single cylinder or warehouse group, double row external scaffold project shall be applied according to the perimeter of single cylinder external sideline multiplied by the height from the design outdoor floor to the upper opening of warehouse in square meters
.
（11） The scaffold of water (oil) storage tank shall be calculated in square meters by multiplying the perimeter of the outer wall by the height between the outdoor floor and the top surface of the tank wall
.
When the height of water (oil) storage tank is more than 1.2m from the floor, double row external scaffold project shall be applied
.
（12） For equipment foundation scaffold, double row scaffold project shall be applied according to its perimeter multiplied by the height between the floor and the contour top sideline in square meters
.
（13） The quantity of building vertical closure is calculated according to the vertical projected area of the closure surface
.
（14） The vertical safety net is calculated in square meters by multiplying the actual length of the net part by the actual height
.
（15） Pick out safety net is calculated according to the horizontal projection area
.
