Abstract
A panel for a concrete forming structure including two siderails and two end rails extending between and connecting the ends of the siderails. A corrugated, aluminum core member is located inside the area formed by the rails and substantially covers the interior space of the panel. An outer structural sheet extends between the two sets of rails and has the core member connected thereto. An inner plywood sheet extends between the two sets of rails and is attached thereto. The core member is also connected to the plywood sheet. Rigid insulating material fills the inner and outer troughs formed by the corrugated member. A tubular connecting member is provided to connect the afore-mentioned panel to an adjacent panel. It has two connecting flanges extending outwardly from one side and bolt receiving slots formed in each of these flanges. The tubular member has aligned holes therein for passage of a tie rod and special projections that form a channel to receive flanges provided on the edges of the panels.
