## 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 U-shaped 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 U-shaped 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.

## Claims

### Claim 1

A form for receiving liquid concrete therein comprising:
a plurality of elongated wall members each wall member having first and second ends and an inner surface wherein the elongated wall members are contiguously positioned in end to end alignment to form an enclosure, wherein a first end of one elongated wall member is adjacent a second end of an adjacent wall member;
means for connecting adjacent wall members wherein the connecting means includes a key attached to the inner surface of the wall proximate to the first end and extending beyond the first end and an interlocking bracket attached to the inner surface at the second end for receiving said key; and
further including a support brace having flanged ends, said support brace extending to opposing wall members, wherein the inner surfaces of the opposing wall members have locking shelves for receiving the flanged ends of the support brace.

### Claim 2

A form for receiving liquid concrete therein comprising:
a plurality of elongated wall members each wall member having first and second ends and an inner surface wherein the elongated wall members are contiguously positioned in end to end alignment to form an enclosure, wherein a first end of one elongated wall member is adjacent a second end of an adjacent wall member;
means for connecting adjacent wall members wherein the connecting means includes a key attached to the inner surface of the wall proximate to the first end and extending beyond the first end and an interlocking bracket attached to the inner surface at the second end for receiving said key, wherein the key has a U-shaped configuration defined by two extending legs and the interlocking bracket forms a pair of slots for individually receiving an extending leg.

### Claim 3 (depends on 2)

The form of claim 2, wherein the first slot is sized to tightly receive one extending leg and the second slot is larger than the first slot.

### Claim 4 (depends on 3)

The form of claim 3 further including a support brace having flanged ends, said support brace extending to opposing wall members, said flanged ends extending horizontally wherein said second slot is sized to tightly receive one extending leg and one horizontal flanged end to secure adjacent wall members together.
