Abstract

An concrete form system includes opposed polystryrene panels stacked to form a pair of parallel, spaced-apart walls, at least one of the walls having panels which are smooth on their inward surface. Tie slots are formed in the upper and lower edges of the panels and are spaced evenly such that slots in vertically abutting panels are aligned. The panels are horiziontally staggered to strengthen vertical joints. A single tie is utilized to interlock two vertically abutting panels in each wall. A special tie design is used with the smooth-faced panels to allow the panels to be removed after a concrete wall has been formed. Another embodiment of the tie design utilizes an enlarged outer paddle with a projecting rib which allows connection of vertical walers directly to the tie.
