Abstract
Panels are formed from foamed plastic or the like, with anchor members embedded in the inner faces and having connector engaging portions extending from one face of the panel. A pair of panels is held in spaced and parallel relationship by a plastic connector member which is slidably engaged within the anchor portions extending from the panels. The anchor portions are situated adjacent each end of the panels and have upper and lower extending portions spaced from the upper and lower edges of the panels. The connectors each have upper and lower anchoring engaging portions so that a four point connection is made between each pair of panels. Concrete may then be poured between the panels which act as forms and remain in place.
