Abstract:
In a forming panel for use in construction of a self-sustaining concrete structure from a concrete mix containing flowable constituents which are capable of migrating from a concrete pour during curing of the mix, the improvement comprising:a segment of the forming panel which defines a forward-facing, concrete-receiving surface located in a position oriented for receiving at least a part of the concrete pour thereagainst during curing of the mix and having a margin in disposition such that said flowable constituents in the concrete pour may migrate past the margin, said segment further defining a second surface adjacent said margin and leading rearwardly away from the concrete-receiving surface; and a flexible barrier element mounted in spaced relationship to said concrete-receiving surface on said second surface in proximal relationship to said margin and operable to impede migration of the constituents out of the pour past the barrier element until the concrete mix has cured, said segment of said forming panel including a face plate having said concrete-receiving surface thereon and said forming panel further including a frame upon which said face plate is mounted, and wherein said second surface is on said frame, wherein said margin is a perimeter margin of said face plate and said frame includes at least one elongated rail positioned adjacent said perimeter margin, and wherein said flexible barrier element is elongated and mounted on said rail in longitudinal alignment with the perimeter margin.
