Abstract:
A system for forming structures of concrete or other pourable, hardenable materials comprising:two or more adjacent pairs of vertical forming panels, each pair of panels spaced apart and defining a forming cavity to receive concrete or other hardenable materials and one panel defining an inner wall and the other panel defining an outer wall; at least one tie rail between each adjacent pair of forming panels, the tie rail engaging edges of the panels, substantially fixing each panel in a predetermined position relative to the other panels, the tie rail having a first retaining section holding the edges of the inner wall forming panels and a second retaining section holding the edges of the outer wall forming panels, and at least one web extending between the first and second retaining sections, the web having one or more retainers sized and positioned to hold reinforcing members in a predetermined position and orientation between the outer wall and the inner wall; the tie rail retaining sections extending generally along a substantial length of the vertical edges of the panels, and at least one portion of the retaining sections extending over the surface of the panel edges a distance sufficient to inhibit displacement of the panel edges from the retaining sections when the panels are subject to pressure outwardly exerted by concrete or other hardenable materials within the forming cavity.
