How To Calculate Staircase Concrete Quantity
Concrete amount calculation is that the commencement of the method of building a concrete steps. individuals got to knowledge a lot of of the required materials ought to they get therefore the construction would go basically. But, this is often a large operation, showing the scale of the steps and therefore the manner they’re gonna be build. solely this manner they'll calculate the requirement of the materials for the development.
Staircase quantity
Staircase quantity
R.C.C. work (staircase)
Base Toe wall
L X B X H 1.10 x 30 cm x 23 cm 1.10 x 0.30 x 0.23 = 0.076 cu. Meter
No. of Toe wall is one
Therefore, total volume of Toe wall = 0.076 x 1 = 0.076 cubic meter
Volume = L X B X H
Length of waist slab = L = 3.05 meter Breadth of waist slab = 1.15 meter
Adding bearing 15 cm 1.15 cm + 1.15 cm = 1.30 meter
Thickness of waist slab is 15 cm.
Therefore, volume of waist slab = L X B X H
Volume of waist slab = 3.05 x 1.30 x 0.15
Volume of waist slab = 0.594 m3
No. of waist slab is 2
Therefore, volume of waist slab = 0.594 x 2 = 1.190 m3
Landings
Length of landing = 2.30 meter
Add 15 cm bearing both ends
i.e. = 2.30 + 15 cm + 15 cm = 2.60 meter
Breadth of landing is 1.15 cm
Add 15 cm bearing as per drawing
i.e. = 1.15 cm + 15 cm = 1.30 meter
Thickness of landing slab is 15 cm i.e. 0.15 meter
Therefore, volume of landing = L X B X C
Volume of landing = 2.60 x 1.30 x 0.15
Volume of landing = 0.507 meter
No. of landing is 2
Therefore, total volume of landing = 0.507 x 2 = 1.014 cubic meter
Steps without slanting
Length of steps without slanting
= 2.3 m / 2 (As per drawing)
= 1.15 meter
Breadth of steps without slanting
= ½ x 0.25 (Triangle formula)
= 0.125 meter
Height of step without slanting is 16 cm
i.e. 0.16 meter
therefore, volume of step without slanting = L X B X H
volume of step without slanting = 1.15 x 0.125 x 0.16
volume of step without slanting = 0.023 m3 (cubic meter)
no. of steps is 20
therefore, total volume of steps without slanting = 0.023 x 20 =0.460 m3
steps with slanting’s
length of steps with slanting’s
= 2.3 m / 2 (As per drawing)
= 1.15 meter
Breadth of step with slantings
= ½ x 0.03 ( ie. 0.28 – 0.25 = 0.03) = 0.0153 meter
Height of step with slantings is 16 cm i.e 0.16 meter
Therefore, volume of step with slanting = L X B X H
Volume of step with slanting = 1.15 x 0.0153 x 0.16
Volume of step with slanting = 0.00281
No. of steps with slanting is 20
Therefore, total volume of steps with slanting = 0.00281 x 20 = 0.055 m3
Total volume of staircase is = 0.076 + 1.190 + 1.014 + 0.460 + 0.055
Total volume of staircase is = 2.765 m3 (cubic meter)
