Claim:
An insulation insert shaped to be embedded in a concrete wall structure, said insert consisting essentially of: a) an elongate, rigid foam insert including an integrally formed base section and a single cap section that is symmetrically disposed on the base section, which has a bottom outer base surface and opposed base end sections each with a bottom, outer edge portion surface, an upper, outer edge portion surface to be embedded in the concrete of a concrete wall structure, and each base end section extends to an opposed outer flat end side surface that is perpendicular to said bottom and upper outer edge portion surfaces, said cap section having a top peak cap surface to be embedded in the concrete of a concrete wall structure; b) said bottom outer base surface being opposed to said upper, top peak cap surface and extends between said opposed outer flat end side surfaces, said bottom outer base surface having a length sufficient to form a vertical interior surface expanse of the concrete wall structure, and said outer flat end side surfaces are sufficient to enable said side surfaces of a plurality of inserts to be placed side-by-side to form a horizontal interior surface expanse of the concrete wall structure and said plurality of inserts thereby provides a corrugated shaped internal construction form including cap section side walls of adjacent inserts to provide a corrugated shape to the concrete that acts to create between cap section side walls of adjacent inserts vertically placed concrete columns in the concrete wall structure whereby said columns provide additional lateral and vertical strength to the wall structure and implements structural integrity to a concrete wall structure; c) said opposed base end sections each extend about 3″ outwardly from opposed intersections of the outer cap surface of said single cap section with the upper, outer edge portion surfaces to the outer flat end side surfaces of the opposed base end sections for disposing an entire top peak cap surface and upper, outer edge portion surfaces of each of said plurality of adjacent inserts in a concrete portion of said concrete wall structure; d) said opposed base end sections and cap section each have a thickness of about 2″ so that the insert has a thickness of about 4″ at its base and cap sections; e) said insert has an overall width between the outer, flat end side surfaces of the opposed base end sections selected from a group of about 15¾″ to about 17¾″, said top peak cap surface of said cap section has a width selected from a group of from about 8″ to about 10″, and the width between intersections where the symmetrically disposed cap section intersects the base section is from about 10″ to about 12″.
