Abstract
A three-layer insulated concrete panel includes as the middle layer an insulating slab having grooves which provide a form for casting of concrete supporting ribs integral with a layer of concrete cast over the grooved face. A layer of material, such as particle board, is bonded to the ungrooved face of the slab. In preparing the panel, the slab is placed on a flat surface with the particle board face down. Forms are then placed in spaced-apart relation to panel edges, and concrete is cast into the forms and grooves and over the grooved panel face. The insulating slab provides a form for casting of supporting ribs and is permanently retained in the panel, giving it a high insulating value.
Claims25
A load-bearing building panel comprising:
- a rigid slab of insulating material having a first face, a second face, and a plurality of edges, said first face having defined therein a plurality of grooves extending substantially into said slab and forming channels for containing supporting ribs;
- and
- concrete integrally cast into said grooves, over said first face, and outside of and in contact with said edges, forming supporting ribs within said grooves and integral therewith a layer of concrete covering said first face and edge frames outside said slab edges.
A load-bearing structural panel comprising:
- a rigid, solid, rectangular-shaped slab of insulating material having a first face and a second face and four edges;
- said first face having defined therein a plurality of grooves extending substantially into said slab and arranged parallel to edes of the slab, intersecting one another and forming a waffle-shaped pattern;
- a layer of finishable material covering said second face of said slab and bonded thereto;
- concrete filling said grooves and forming ribs therein;
- a layer of concrete covering said first face;
- a concrete edge frame enclosing said edges of said slab;
- and
- said concrete ribs, concrete layer, and concrete edge frame being integrally cast.
The method of making a load-bearing building panel comprising:
- providing a rectangular slab of insulating material;
- bonding a sheet of nailable, wood-based sheet material to one face of said slab so as to cover that face;
- cutting grooves in the opposite face of said slab so as to provide a waffle-shaped pattern therein;
- placing the grooved slab on a flat surface within the grooved face up;
- placing forms around the edges of the slab and spaced apart therefrom;
- and
- casting concrete into said grooves, over said grooved face of the slab and into the space between said forms and said slab edges so as to produce integral concrete forming a layer covering one face of the slab, ribs extending the slab and an edge frame enclosing the slab edges.
A load-bearing building panel comprising:
- a plurality of rectangular slabs of insulating material, each slab having a first face and a second face and four edges generally perpendicular thereto, said slabs being disposed in a rectangular array with their first and second faces coplanar with one another and with edges of adjacent slabs being slightly spaced apart from one another;
- at least one groove in said first face of said slabs and extending across said array transverse to said spaced-apart edges;
- and
- concrete integrally cast into the spaces between said adjacent slab edges, into said grooves, and outside of and in contact with slab edges at the outside of said array, forming supporting ribs in the spaces between slabs and in said groove, a layer of concrete covering said first face and edge frames outside said slab edges at the outside of said array, said concrete layer, ribs, and edge frame including reinforcing means.
A load-bearing building panel comprising:
- a plurality of rectangular slabs of insulating material of uniform thickness disposed edge-to-edge in a rectangular array, the array having a first face and a second face and outside edges;
- said first face having defined therein a plurality of grooves for containing supporting ribs;
- and
- concrete integrally cast into said grooves, over said first face, and outside of and in contact with said outside edges, forming supporting ribs in said grooves and integral therewith a layer of concrete covering said first face and edge frames outside said outside edges, said concrete layer, ribs, and edge frame including reinforcing means.
