ABSTRACT:
A method and apparatus for attaching sheets of wallboard to an EPS side panel and concrete wall assembly. A metal fastener strip is positioned against the outer surface of the outwardly facing side panels with its upper edge a predetermined distance below the ceiling line, prior to pouring of the concrete. Nails are pushed through longitudinally spaced-apart holes in the metal strip with their tips projecting well into the cavity defined between the opposed side panels. The concrete, when placed and cured, captures the nails, creating a mechanical connection to the metal strip. After the concrete is placed and cured, an adhesive is spread over the outwardly facing panels and the sheet of wallboard is placed in position. The wallboard is secured to the panels by hammering self-tapping drywall screws into the metal strip. The holes in the metal strip are countersunk to define a concentric recess around each hole, the metal strip being pushed into the side panels so that the recesses project into the panels. The heads of the nails fit flush within the recesses. The nails are secured against movement during placement of the concrete by placing speed washers over their tips and pressing the speed washers against the inner surface of the outwardly facing side panels.
