ABSTRACT:
A concrete wall panel for tilt-up construction provides polymeric peripheral elements defining panel and orifice edges and medial fastening strips extending in the panel between the peripheral elements, all of which remain as part of the finished panel to accept traditional self-penetrating nail, screw and staple fasteners historically used in wood construction. The peripheral elements are of solid configuration to provide a form for pouring plastic concrete that forms the panel embodying them. The fastening strips extend through the panel between opposed panel surfaces and are formed by two initially releasably interconnected elements defining voids therebetween to allow thickness adjustment and convenient placement and support of structural components within the panel. The fastening strips define spaced areas to receive traditional wood fasteners and may carry index strips on opposed exposed surfaces to visually indicate strip location and fastening areas. The peripheral elements allow joinder of adjacent panels with each other and both the peripheral elements and the fastening strips allow joinder of structural elements on one or both panel surfaces by self-penetrating fasteners of wood construction.
