ABSTRACT:
A reinforced box-like structure for forming a void area in a concrete formation. The structure includes a bottom panel having a plurality of spaced apart, parallel base partitions and a top panel having a plurality of spaced apart, parallel top partitions. The base partitions extend across the bottom panel and in a direction normal to the bottom panel, and the top partitions extend across the top panel and in a direction normal to the top panel. Each of the base partitions and top partitions include a plurality of double-thickness walls with a plurality of slots therein and flat top edges between the slots. The structure is assembled by superimposing the top panel over the bottom panel such that the base partitions extend transversely relative to the top partitions. Thus, the slots in the base partitions register in interlocking relationship with the corresponding slots in the top partitions, wherein the base partitions extend substantially to the top panel and the top partitions extend substantially to the bottom panel to create a cellular box-like structure that generally fills a space between the bottom panel and top panel with the flat top edges engaging the respective top or bottom partition.
