Abstract
A construction panel is formed of a plurality of elongate subpanels where each subpanel comprises a plurality of expanded polystyrene blocks placed end to end. Tensioning cables pass over the inner and outer surfaces of the subpanels between tensioning plates positioned at each end of the subpanels. Tensioning the cables imparts longitudinal compression in the subpanels, such that the blocks of the subpanels act monolithically. The inner and outer surfaces of the subpanels are longitudinally convex. The panel may be corrugated. The subpanels may be interlocking to form the construction panel.
