Abstract:
A method and apparatus for forming a formwork for a ribbed or waffle concrete slab is provided. The apparatus includes a rectangular block having a ledge around the base, the ledge having a dimension of half the desired width of the base ribs of the concrete slab, and a keystone connector. The keystone connector has an engagement portion configured to attach to an engagement portion on each block. In a method, the blocks are laid out so that the ledges of adjacent blocks are in contact. A keystone connector is then placed at each intersection of four blocks by attaching the respective engagement portions of the keystone connector and each block so that the keystone connector holds each of the four blocks in place relative to one another. The keystone connector is also configured to retain a reinforcing rod laid in the channel between adjacent blocks.

Claim (Index 9):
A formwork as claimed in  claim 8 , wherein the keystone engagement portion comprises a pin with a resilient barb in the vicinity of an end of the pin, the resilient barb configured to deform when the keystone engagement portion is pushed into the block engagement portion and to return to its original shape when the keystone engagement portion is fully locked onto the block engagement portion.
