Abstract: A building panel structure and a process for manufacturing the structure are disclosed. The structure comprises a concrete layer disposed on the outside of a building, an insulating material comprising polyurethane in the center of the structure and a corrugated steel layer on the inside of the building. A reinforcing assembly comprising an upper channel and a lower channel that are connected using a plurality of studs is embedded inside the building panel structure. The process of manufacturing the building structure comprises placing a wet concrete layer inside a container, positioning the reinforcing assembly in the container inside the wet concrete, setting the concrete layer and forming the polyurethane layer between the concrete and corrugated steel layers by an in-situ chemical reaction.

Abstract: A building panel structure and a process for manufacturing the structure are disclosed. The structure comprises a concrete layer disposed on the outside of a building, an insulating material comprising polyurethane in the center of the structure and a corrugated steel layer on the inside of the building. A steel plate overlays the top of the panel and a lip member attached to the plate and perpendicular to it covers a portion of the corrugated steel layer exposed surface. U-shaped loops are welded to the plate and embedded in the concrete to provide structural integrity and shear resistance to the structure. The process of manufacturing the building structure comprises positioning the plate, lip and loop assembly in a container, setting the concrete on the bottom of the container over the loops and forming the polyurethane layer between the concrete and corrugated steel layers by an in-situ chemical reaction.
