Abstract
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.
