POD RAIL 40MM - SPIKED
The 600mm long pod rail is designed to spread the load of the top reinforcing mesh and maintain integrity of cover over the polystyrene pods. Under load, single bar chairs will compress into or possibly punch through the pods.
A paper presented at the 2001 CIA conference in Perth, concludes that the presence of continuous bar chairs does not have the significant effect on the slab strength. Similarly, it can be seen that the pod rail allows superior concrete flow compared to the continuous chair demonstrated. Only two rails are required per pod, which are placed when the pods are fixed. The reinforcing mesh is simply lowered onto the rails, without having to “chair up” under each wire.
This method of construction improves productivity substantially and reduces the amount of bending by the concreter or steel fixer. A minimum bottom cover of 40mm is maintained.
