Composite foam and concrete wall and method of constructing the same

1. A composite foam and concrete panel comprising:

a first layer, a major portion of which is foam, the first layer having a top surface, a bottom surface, a left wall surface and a right wall surface, a front surface and a back surface wherein the foam layer comprises at least two foam panels that define a seam that is substantially parallel to the top surface and the bottom surface when lifted to a vertical position, wherein the foam layer further comprises:

a plurality of spaced apart channels extending into the foam layer from the front surface from proximate the bottom surface to proximate the top surface, wherein each of the plurality of spaced apart channels is a distance from the left wall surface and the right wall surface, wherein the plurality of the spaced apart channels are substantially perpendicular to the seam; and

a top channel extending into the foam layer from the front surface along the top surface from proximate the left wall surface to proximate the right wall surface wherein the top channel is substantially parallel to the seam and substantially perpendicular to the plurality of spaced apart channels;

a second structure secured to the front surface of the first layer wherein a majority of the second structure comprises concrete, where the second structure comprises:

a layer of concrete substantially covering the front surface of the foam layer, the layer of concrete having thickness;

a plurality of pilasters comprising concrete and extending from the layer of concrete and located within the plurality of spaced apart channels; and

a top pilaster comprising concrete and extending from the layer of concrete and located within the top channel;

a top plate secured to a top surface of the concrete structure from the left surface to the right surface; and

spaced apart lifting mechanisms secured within the second structure and located proximate the top surface of the second structure wherein the spaced apart lifting mechanisms are configured to be engaged by a lifting force such that the panel can be raised to a substantially vertical or standing position, wherein as the seam is substantially perpendicular to the gravitational forces on the panel as the panel is lifted to the vertical position.

2. The composite foam and concrete panel of claim 1 and wherein the plurality of spaced apart channels and the plurality of pilasters comprise a dovetail cross-section.

3. The composite foam and concrete panel of claim 1 and wherein the spaced apart lifting mechanisms are positioned through the top plate such that an upper portion of each the spaced apart lifting mechanisms are accessible above the top plate.

5. The composite foam and concrete panel of claim 1 and wherein the concrete layer has a nominal thickness in the range of about 2 inches to about 6 inches such that the wall is a structural, load bearing wall.

6. The composite foam and concrete panel of claim 1 and further comprising:

a form secured to the front surface of the first layer and extending about a perimeter of the first layer;

wherein the second structure comprising concrete layer is placed onto the front surface of the first layer wherein the form is a structural component of the wall and is retained to the foam layer by the concrete layer and provides a finished surface to the second structure.

7. The composite foam and concrete panel of claim 6 and wherein the plurality of spaced apart channels and the plurality of pilasters comprise a dovetail cross-section.

8. The composite foam and concrete panel of claim 6 and wherein the first layer has a nominal thickness in the range of about 3 inches to about 10 inches.

10. The composite foam and concrete panel of claim 6 and wherein the form comprises a plurality of brackets wherein each bracket comprises:

a bottom portion configured to be positioned on the first layer;

an angled tang extending from the bottom portion and configured to be positioned within an angled slot within the first layer;

a bracket wall extending from the bottom portion wherein a maximum thickness the second structure defined by a height of the bracket wall; and

a screed portion substantially parallel to the bottom portion wherein the brackets are retained to the second structure and forms a finished surface.

11. The composite foam and concrete panel of claim 1 , wherein there are no thermal bridges through the foam of the first layer.

12. The composite foam and concrete panel of claim 1 , wherein the spaced apart lifting mechanisms are accessible through the top plate.
