What size are waffle pods?
Waffle Pods are made of polystyrene 1090mm square. They come in four thicknesses for use in different sites: 175mm. 225mm.
How much concrete is in a waffle pod slab?
Waffle Pod Accessory Calculations To commence, divide the total area m^2 by 1.51 to get the number of Waffle Pods required for the concrete slab. Multiply the number of waffle pods by 1.40 to calculate the number of 4 way spacers. Next, divide the total number of 4 way spacers by 3 to calculate number of 2 way spacers.
Does waffle slab need Beam?
Characteristics of Waffle Slabs Waffle slabs are generally suitable for flat areas. Volume of concrete used is very less compared to others. The reinforcement in the waffle slab is provided in the form of mesh or individual bars. Separate excavation for beams is not required in case of waffle slab.
How big are waffle slabs?
Waffle slab design Slab depth is typically 75 mm (3 in) to 130 mm (5 in) thick. As a rule of thumb, the depth should be 1⁄24 of the span. The width of the ribs is typically 130 mm (5 in) to 150 mm (6 in), and ribs usually have steel rod reinforcements. The distance between ribs is typically 915 mm (3 ft).
Is waffle slab load bearing?
Load bearing the capacity of waffle slab is higher than other types of the slab. Waffle slabs have good structural stability. The construction of a waffle slab is very speedy and fast.
What are the thicknesses of the waffle pods?
Waffle Pod are made from polystyrene and are 1090mm square. They come in four thicknesses for use on different sites: E 175mm – Suitable for “A” Soil Classification sites and special purposes*. E 225mm – Suitable for “S” and “M” Soil Classification Sites*.
What are the dimensions of a waffle slab?
The design of the waffle slab depends upon the total area on which the waffle slab is required. The thickness of the waffle slab is generally range from 80 mm to 100 mm. The overall depth of the waffle slab is limited to 300 mm to 600 mm. The width of the beam in the waffle slab ranges from 100 mm to 200 mm.
Is there a ‘deemed to comply’ design for waffle slab?
There is no ‘deemed to comply’ design for waffle slabs for extremely reactive sites (Class E sites). There is no deemed to comply raft footing design for Class E sites either – the footing and slab system for a Class E site must be designed by a relevantly qualified engineer.
How do you calculate the number of waffle pods?
Waffle Pod Accessory Calculations 1 To commence, divide the total area m^2 by 1.51 to get the number of Waffle Pods required for the concrete slab. 2 Multiply the number of waffle pods by 1.40 to calculate the number of 4 way spacers. 3 Next, divide the total number of 4 way spacers by 3 to calculate number of 2 way spacers.
