Pod star
  Go Back

The pod star is a sturdy 4-way spacer that forms a 110mm wide internal beam between polystyrene pods or pods made from other materials. The patented design incorporates an easy central feed system for reinforcing bars in both directions. The supporting frame that holds the pod is 60mm x 85mm and ribbed for better grip. Cover from the bottom of the beam is 50mm.

Pod star extension
  Go Back

The extension, clips onto the pod star to form a 270mm or 300mm wide edge beam. This eliminates the need to purchase large, cumbersome components to form the edge beam. Nodules on the upper surface of the extension are designed to locate the longitudinal wires on trench mesh, or loose bars depending on the design. The end nodule will locate the wire or bar a minimum of 45mm from the edge of the beam. Cover from the bottom is also 50mm.

Pod rail
  Go Back

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 a significant effect on the slab strength. Similarly, from fig. 3 of the same paper, 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.
