Patent ID: 8776468

Claim:
A panel for construction of a composite insulated concrete roof or floor comprising: (a) two elongated studs, each comprising a planar web section and an upper flange and an lower flange integrally extending from said web section, said two elongated studs aligned in parallel in a longitudinal direction of said studs, with said flanges facing each other; each of said elongated studs having multiple through-holes on said planar web section, spaced apart along said stud in the longitudinal direction; (b) a plurality of deformation resistant elements protruding from said upper flange of each of said studs, said deformation resistant elements spaced apart along said upper flange of each of said studs in said longitudinal direction; and (c) an insulation board secured between said two elongated studs, said insulation board having upper and lower surfaces, two side edges and a thickness less than a width of said web section of said stud, each of said side edges of the insulation board being against an internal surface of the web section of the studs and covering said multiple through-holes on the web section of the studs, and said lower surface of said insulation board being disposed against said lower flanges of said studs, thereby establishing a distance between said upper surface of said insulation board and said upper flanges of said studs and forming a hollow space therebetween for filling concrete therein.
