ABSTRACT:
An easily assembled concrete form including a plurality of elongated wall members manufactured by roll forming and connected together to define an enclosure. Each wall member has a first end and a second end, an inner surface and an outer surface. Attached to the inner surface of the wall member at the first end is a key having legs extending beyond the first end of the wall member. Attached to the inner surface of the wall member at the second end is an interlocking bracket having two vertically spaced slots for receiving the legs of the key to connect adjacent wall members together. One of the slots is enlarged for also receiving an extending flange from a support bracket to frictionally maintain the U-shaped key and interlocking bracket in a locked relationship.
