ABSTRACT:
A wall panel and a method of forming the panel. The panel includes an outer concrete layer, an inner concrete layer, and a central insulation layer positioned between the concrete layers. The inboard vertical faces of the inner and outer concrete layers have laterally spaced vertical ribs in confronting relation to each other and the central insulation layer includes laterally spaced vertical grooves on each vertical side face thereof sized and configured to nestingly receive the ribs on the inboard faces of the inner and outer concrete layers. A reinforcing rod structure of ladder configuration serves to tie the layers together with one vertical stile of each ladder construction embedded in the outer concrete layer, the other vertical stile of the ladder structure embedded in the inner concrete layer, and the rungs interconnecting the stiles extending between the confronting ribs through the central insulation layer. A method of forming the wall panel is also disclosed.
