So the inclined length of the waist slab is. That is. I Want if you Explained, How to Calculate the Reinforcement Quantity at Stair, will be helpful for us. We just need to apply some geometric formula. How to Estimate Stairs. Inclined length of waist slab isn’t normally shown in the drawing. Top tread on level with ex-isting landing. In this case, divide 104.5 by 16 to get 6.53 inches. Flight: A staircase normally has two flights. For example, if you have 1-by-10-inch boards, which are actually 9.25 inches wide, divide 150 by 9.25 to get 16.21 steps. Step: A step is normally a triangular-shaped part of a staircase which sits on an inclined slab (Waist slab). § Stairs cantilevering from a central spine beam. While measurements of length are conventionally longer than those of width when considering rectangles, in the case of steps, the width is usually the longer side. This construction video tutorial shows the detailed process on how to estimate a staircase with use of excel sheet. Double-check the measurements and calculations for accuracy. 0000001872 00000 n 0000001893 00000 n b- Longitudinally supported (in the direction of movement): These stairs span between supports at the top and bottom of a flight and unsupported at the sides. 5 Estimate actions on staircase EN 1991-1-1 6 Analyze structure to obtain maximum bending moments and shear forces EN 1992-1-1: Sec.

Filed Under: Estimating And Costing Tagged With: Concrete, Staircase, I fully benifite for thise process in webside. 0000017583 00000 n The item tab contains base slab, step, landing platform, landing beam, RCC railing, CF1 etc. 0000003157 00000 n Measure your floor from the spot where you want the stairs to begin at the bottom step to the base of the wall at the place where the top step will meet the upper floor, then convert the number to inches. Perimeter of rectangle = 2 (Length x breadth), The perimeter of square = 4 x Side Length, The perimeter of triangle =  a + b + c    [ a,b,c are side length of traingle]. Riser: Riser is the vertical portion of steps. Some people install these without handrails for a minimalist look, but this makes the stairs very dangerous. Never Miss an update Click on “Allow US” and make us allow or Click on Red notification bell at bottom right and allow notifications. Newel: A vertical post which might provide support for either the handrail, or support for the upper end of an outer string. 0000011667 00000 n 0000015706 00000 n ��J%���]};��災���tz+����e���}����4|}���B{�®} Measure the exact height where your stairs will go, remembering to begin at the surface of the lower floor to the surface of the upper floor, not merely to the ceiling. In simple words, the calculation of the shuttering area of the staircase. 0000009431 00000 n /Filter/FlateDecode I was very important on my side, I need civil engineering books for estimating. >> I’ll write about this later. b. 0000013779 00000 n So, the concrete volume for the waist slab is, = inclined length of waist slab x width of waist slab (width of a step) x thickness of waist slab. All the below mentioned values are considered from this image. Convert the total height measurement to inches with your calculator. 0000013801 00000 n 0000011442 00000 n In this example, the estimated number of steps needed is 15, each with a 10-inch run and a 6 31/32 riser. 0000002689 00000 n So, the concrete volume for the landing is. in staircase estimates as a function of the number oftrials in a run, the spacing ofthe stimuli, the method of calculating the estimate, and theshape of psychometric function. Because you can't have a partial step, call it 16 steps. 5 Estimate actions on staircase EN 1991-1-1 6 Analyze structure to obtain maximum bending moments and shear forces EN 1992-1-1: Sec.

The formula defining the level of convenience is as follows: depth of a tread + 2 heights of a tread = 63±3 cm. Calculating the concrete quantity for a staircase is a little bit tidy as it is inclined and has geometrical shapes. /CreationDate (D:20111212102628+02'00') of the stair H, then look up the closest figure in the column to the right Example: Base line (L) = 3,5 m Height of stair (H) = 2,5 m L = 3,5 = 1,4 the angle of inclination is 35° H 2,5 L H. 75 EXAMPLES OF STAIRCASES WITH ONE FLIGHT EXAMPLES OF STAIRCASES WITH SEVERAL FLIGHTS Top tread one step height below existing landing. of steps = 20, Steps are in the shape of a triangle, therefore, Shuttering area for each step = Side(i)+Side(ii)+Side(iii), Total volume of concrete required for steps = 20 x 0.225 =4.5m2, = Front Area + Back Area + Right Side area +Bottom Area, Shuttering required for Landing =3.3735m2, The handrail is in the shape of a rectangle, therefore, = Front area + Left area + Right area +Back Area, Total shuttering required for Hand Rails = 4 x 5.52 = 22.08m2, Total Shuttering Required for Staircase = Waist Slab Shuttering + Steps shuttering+ Landing shuttering+HandRail shuttering, The total shuttering required for staircase = 10.77+4.5+3.735+22.08 = 41.085m2, Liked the explanation? 0000017561 00000 n Doing the math, you see that 104.5 divided by 15 equals 6.966. line at the sides of a stair. In general, the step size ranges from 60 to 66 cm, therefore an average value is 63 cm. Shuttering area is a perimeter and area calculation. Required fields are marked *. The thickness of the waist slab = 6 inches. Different shapes have different formulas for the perimeter. doing good work. We have already covered What is shuttering? So, often we need to do it manually. It is mainly provided for changing the moving direction of a stair. 0000001454 00000 n Just remember that stairs go from floor to floor, not floor to ceiling. 4 0 obj >>stream Estimation of the shuttering area required for construction of the staircase: Now coming to the calculation part, as mentioned before the shuttering area is calculated individually for different components of the staircase. A staircase has mainly two parts – Step and Landing. Just keep in touch. Now, we need to calculate the concrete volume for landing. 0000003310 00000 n In this article, We are going to explain “Estimation of shuttering required for the construction of the Staircase”. As we have 9 numbers of steps in a flight, so the concrete volume for the steps of the first flight is. because that is just a hair short of 7 inches, it is very close to perfect. Check to see if that number of steps comes out to a good height for each riser by dividing the overall height measurement by the estimated number of stairs. Adjust height and number of stairs as needed for your particular space – allowing room at the bottom of the stairs for clearing doors and for moving furniture upstairs. How to Make a Wall-to-Wall Carpet Into a Stair Runner, How to Use a Builder's Square to Make Stairs. 0000121351 00000 n The shuttering quantity required for the waist slab is : = Side (i)+Side (ii)+Side(iii)+side(iv)+side(v), = 3.35×1.20+1.20×0.15+1.20×0.15+3.35×0.15+3.35×0.15= 5.385m2, Total Shuttering quantity required for Waist slab in Staircase = 5.385×2 = 10.77m2, From fig: width of tread = 0.30m, height of riser = 0.15m , Length of tread = 1.20m, No.
