Abstract: A method and apparatus using foam forms for poured concrete roof and floor decks for on-site concrete structural joists is shown that may be integrated into the concrete deck formed by the forms or otherwise used as structural supports. Greater joist strength results from providing a communication channel in the forms between an opening in C channel metal studs used in such panel forms and a space between piers that forms the main concrete beam portion of a finished concrete structural joist. By providing such flow of concrete, when the joist is completed, the concrete structural joint is stronger because the concrete is disposed inside of the C channel studs and continuously between the inside of the C channel studs and the main concrete beam portion. The concrete thereby interlocks the C channels to the main concrete portion of beam.
