Abstract
Abstract An insulated concrete form system including two longitudinally-extending side panels, each side panel having an exterior surface and an interior surface, wherein the interior surface of one side panel faces the interior surface of the other side panel and wherein the interior surfaces are laterally spaced apart from each other so that a cavity is formed therebetween, a longitudinally-extending wire re-bar disposed in the cavity formed between the side panels, and at least two connector members. The wire re-bar acts both as a bridging element between the two side panels and as the horizontal structural reinforcement of the concrete (or similar material) placed into the cavity between the side panels. A portion of each connector member is integrally formed within a portion of one side panel so that one connector member is formed within a portion of each of the side panels. Each connector member has an end plate and at least one gripping section, in which the gripping section is adapted to receive a portion of the wire re-bar therein. The gripping sections extend into the cavity formed between the side panels, wherein each connector member in one side panel is spaced apart from all other connector members in the other side panel.
