How do you calculate shuttering material for a slab?
Let’s get started. The length of the slab = 50 feet. The width of the slab = 30 feet. Total covered area = Length x Width = \%0 x 30 = 1500 sft.
What is props in slab?
Propping is a system of structural members used temporarily to support loads during construction. The forces arising from these loads must be fully resolved, using props or columns to provide all the support needed for the work under construction, such as beams, formwork, etc.
How do you calculate shuttering props?
No. of props to be used under shuttering depends on the plan of building. Like we have thumb rule that prop near column face will be at distance of 9inch. And then regular props supporting slab or beam will be at a distance of 300–600mm(approx).
How do you calculate shuttering quantity for a footing?
A. Square Footing:
- Volume of concrete = Area of sq. footing x Depth of sq footing. Area of sq. footing = L x B = 0.5 x 0.5 = 0.25 m² Volume of concrete = 0.25 x 0.25 = 0.0625 m³.
- Shuttering area = 2 (L + B) x D. = 2 (0.5+0.5) x 0.25. = 0.5m²
- Bitumen paint area = Shuttering area + (Top area of footing – column area)
How do you calculate scaffolding quantity?
Divide the total height measurement by the height of a single scaffolding section. This will determine the total number of rows of scaffolding the project will require. Multiply the number of rows by the number of columns to find the total number of scaffold sections necessary for the project.
How much load a prop can take?
Metal props are the most commonly used, and can be painted, galvanized, zinc plated, etc… They are classified according to their load capacity (between 500 and 3000 kg) and their working height (generally covering a span height between 2 and 6 meters).
What is the minimum propping period of beams and slabs of various spans?
Roughly proping period is 4 to 7 days. If span of beam is upto 6m it is propped for 14 days and above 6m is 21days. If span of slab is upto 4.5m it is propped for 7 days and above 4.5m is 14 days.
