ABSTRACT:
A metal concrete joint form is shown supported on a plurality of interlocking metal stakes for providing a positive, vertically-adjustable, strong locking action between these members. The top end of each stake is flattened and it has a plurality of closely-spaced vertically arranged serrations or ratchet formed on one side thereof. The concrete joint form is an elongated sheet metal member having an inverted hook portion at the top edge of the form with a downturned flange that has its lower edge hemmed on the inside and then folded outwardly to create an upwardly-inclined raw edge of the hem of the flange to serve as a locking pawl for cooperating with the vertical row of serrations or ratchet.
