Patent ID: 8752348

Claim:
A composite building panel consisting of: a central body, substantially parallelepipedic in shape, made from an expanded polymer matrix, having opposite faces, a top surface, and an opposing bottom surface; at least one embedded framing stud extending across the central body between said opposite faces, having a first end embedded in the expanded polymer matrix and optionally a portion of the first end extending above the top surface, a second end extending away from the bottom surface of the central body, and one or more expansion holes located in the embedded studs between the first end of the embedded stud and the bottom surface of the central body, wherein, the polymer matrix is expanded through the expansion holes; a concrete layer covering at least a portion of the top surface and/or bottom surface; optionally a finish surface attached to the first end of the embedded stud wherein the embedded studs optionally have one or more utility holes located in the embedded studs between the bottom surface of the central body and the second end of the embedded studs; wherein the space defined by the bottom surface of the central body and the second ends of the embedded studs is optionally adapted for accommodating utility lines; and wherein the central body optionally includes a male end and a female end; wherein the central body optionally includes openings extending along the length of the central body; wherein T-slots are optionally cut into or molded into a surface of the central body; wherein the central body optionally includes an I-beam channel extending from and open to the top surface of the central body and positioned between a first embedded stud and a second embedded stud and optionally positioning concrete reinforcing bars within the I-beam channel.
