Abstract
Abstract Rectangular sheets of galvanized metal pans are assembled to construct wall forms at the construction site. Each pan includes inwardly bent flanges along its peripheral edges. A course of several pans is erected by joining a horizontal row of pans along abutting vertical side flanges. Several courses are stacked in a vertical plane to construct one face of a wall form. The other face of the form is constructed of similar pans in spaced parallel relationship to the first face. The abutting edges of the pans are either welded or joined by connector plates. A plurality of spaced vertical ribs project outwardly from the face of each pan. The ribs provide contiguous coplanar surfaces against which sheet wall covering may be mounted. Spaced between the ribs are columns of louvers which serve as a lath if the wall is plastered. A further option is the use of an insulation panel, nestably received on the inside face of each pan between the peripheral edges thereof. Concrete is poured into the assembled form and the forms remain permanently affixed to the sides of the concrete core.
