ABSTRACT:
A metal concrete joint form is shown supported on a plurality of spaced metal stakes. The top end of each stake is flattened. The concrete joint form is an elongated sheet metal member having an inverted hook portion at the top edge of the form for receiving the flattened top end of the stake. The main body of the stake has a semi-circular shape in transverse cross section. The invention is a separate holding clip that is made to straddle the main body of the stake and engages beneath the lower edge of the sheet metal form and is snapped into engagement with the stake for holding the sheet metal form against the stake while the concrete is being poured on either side of the form to form a monolithically poured concrete slab.
