## CPC

- E04B 1/14: the elements being composed of two or more materials (of reinforced concrete E04B1/04)
- E04B 2001/3583: {using permanent tensioning means, e.g. cables or rods, to assemble or rigidify structures (not pre- or poststressing concrete), e.g. by tying them around the structure}
- E04B: GENERAL BUILDING CONSTRUCTIONS; WALLS, e.g. PARTITIONS; ROOFS; FLOORS; CEILINGS; INSULATION OR OTHER PROTECTION OF BUILDINGS (border constructions of opening in walls, floors or ceilings E06B1/00; {electromagnetic shielding H05K9/0001})

## Abstract

A structural foam core panel for use in building construction, has inner and outer structural skins with interconnecting insulating foam core to form a structural building unit of standard building height and width such that when several panels are erected and interconnected in series, a load bearing wall is formed. The panel has a top load carrying header plate bridging and secured to the inner and outer structural skins with the foam core provided above and below the header plate. The top header plate spans the width of the panel and extends parallel to a bottom edge of the panel. header plate has an underside spaced from the panel bottom edge, a predetermined height for a top header plate to provide thereby load carrying support above a window opening or a door opening subsequently cut in the panel after interconnection of several panels in erecting a perimeter load bearing building wall.

## Claims

### Claim 1

A structural foam core panel for use in building construction having inner and outer structural skins with interconnecting insulating foam core to form a structural building unit of standard building height and width such that when several panels are erected and interconnected in series, a load bearing wall is formed; said panel having a top load carrying header plate in contact with and bridging and secured to said inner and outer structural skins with said foam core provided above and below said header plate, said top header plate spanning the width of said panel and extending parallel to a bottom edge of said panel, said header plate having an underside spaced from said panel bottom edge a predetermined height to provide thereby load carrying support above a window opening or a door opening subsequently cut in said panel after interconnection of several panels in erecting a perimeter load bearing building wall.

### Claim 2 (depends on 1)

A structural foam core panel of claim 1, wherein said inner and outer skins are adhered to opposite sides of said foam core above and below said top header plate.

### Claim 3 (depends on 2)

A structural foam core panel of claim 2 wherein opposite sides of said header plate are adhered to said inner and outer skins.

### Claim 4 (depends on 1)

A structural foam core panel of claim 1 wherein said foam core is inset for top, bottom and side edges of said inner and outer skins to define a channel about the perimeter of the panel, said channel along said bottom and top of said panel is adapted to receive a bottom and a top building, said channel on each side is adapted to receive a connector stud below said top header plate and a connector cripple stud above said top header plate.

### Claim 5 (depends on 1)

A structural foam core panel of claim 1 wherein said inner and outer skins are of building grade sheeting of a thickness in the range of 7/16" to 3/4" thickness.

### Claim 6 (depends on 5)

A structural foam core panel of claim 5 wherein said standard building width and height is 4' by 8'.

### Claim 7 (depends on 6)

A structural foam core panel of claim 6 wherein said top header plate is of standard dimensional lumber of 2" thickness and a width of 4" or 6".

### Claim 8 (depends on 1)

A structural foam core panel of claim 1 wherein a permanent line is provided across the width of said inner and outer skins, said line defining a top edge of an opening to be cut out for a door or window.

### Claim 9 (depends on 8)

A structural foam core panel of claim 8 wherein said foam is sufficiently pliable to permit removal of foam between an opening top edge cut along said line and said underside of said top header plate and removable to either side of such opening beneath said top header plate to permit installation of a bottom header plate to be secured to said top header plate.

### Claim 10 (depends on 1)

A building perimeter wall erected from a plurality of interconnected panels of claim 1, a cable extending through the interconnected panels adjacent said top header plate of each plate and means to post-tension said cable to reinforce said interconnection of said plurality of panels.
