A precast insulated concrete panel and a method of forming same and a building structure incorporating such panel is described. The precast insulated concrete panel is comprised of an outer insulating skin formed by a rigid layer of insulating sheet foam material connected to a concrete inner wall layer cast on the inner surface of the insulating material. The inner surface of the insulating material has connecting cavities formed therein so that the concrete flows into the cavity and connects to the rigid insulating material through integral plugs of concrete which are set formed with the connecting cavities. Connectors are also formed in the concrete and in the insulation to connect and manipulate the panels and to attach outer finishing building materials to the insulation. These panels may be utilized in a tilt-up construction method and connect to floor slabs to form building structures of more than one storey.
A precast insulated structural concrete panel for use in a building structure, said panel comprising an outer insulating skin formed by a rigid continuous layer of insulating sheet foam material, said insulating sheet foam material having a plurality of spaced apart, discrete connecting cavities formed throughout an inner surface thereof, and a concrete layer formed on said inner surface of said foam material, said concrete layer forming integral concrete plugs for connection to said insulating sheet foam material by concrete extending in said connecting cavities, said panel circumferential edges having a predetermined thickness of concrete covered by a predetermined thickness of said insulating foam material so that when said panel is interconnected with others of said panel a continuous insulating outer barrier is obtained over the panels, connecting means to interconnect said panel with other construction elements of said building structure, said insulated structural concrete panel being an exterior panel for a building structure.
