Abstract

An outer skin or facing of wood sheet material and an inner skin or facing of wood sheet material are adhesively bonded to opposite sides of a core of rigid expanded foam material to form an elongated wall unit having a horizontal length greater than its vertical height. A longitudinally extending upper portion of the wall unit incorporates adhesively bonded members which form an integral continuous beam extending horizontally from one end of the wall unit to the opposite end. The integral beam has a vertical height substantially greater than its thickness for supporting a substantial load above a door or window opening which may be subsequently formed within the wall unit at any selected location between the ends of the wall unit. A plurality of spaced wood furring strips are adhesively bonded to the inner facing of the wall unit and are provided with channels adjacent the inner facing for receiving electrical wiring. The furring strips also function to strengthen the wall unit against wind deflection and provide for an air space between the inner facing and gypsum dry wall sheeting which is subsequently attached to the furring strips. An integral continuous beam may also be located within a lower portion of the unit. In one embodiment, the beam is formed by members which are vertically spaced between the facings to form a box beam, and in another embodiment, the vertically spaced beam members are bonded only to the inner facing to form a "C" shaped continuous beam.

Claims

1. A composite wall panel assembly adapted to simplify the construction of a building structure, comprising an inner facing of wood sheet material and an outer facing of wood sheet material disposed in parallel spaced relation, each said facing extending substantially continuously from the top of the wall panel assembly to the bottom of the assembly, a core of substantially rigid foam insulation material disposed between and contacting said inner and outer facings, a layer of adhesive bonding substantially the entire contacting surface of each said facing to the corresponding side of said core to form a laminated wall unit having a horizontal length greater than its vertical height, a plurality of horizontally spaced vertical wood furring strips positioned adjacent said inner facing and projecting inwardly towards the interior of the building structure, a layer of adhesive rigidly bonding substantially the entire contacting surface of each said furring strip to said inner facing, and said furring strips being adapted to receive inner sheeting material to form an interior wall surface for the building structure.

2. A wall panel assembly as defined in claim 1 and including means defining a window or doorway opening within said wall unit, at least one frame member disposed inwardly of said inner facing adjacent said opening, and said frame member has a thickness substantially the same as the thickness of said furring strips.

3. A wall panel assembly as defined in claim 1 wherein said furring strips project from said inner facing approximately 1.5 inches.

4. A composite wall panel assembly adapted to simplify the construction of a building structure, comprising an inner facing of wood sheet material and an outer facing of wood sheet material disposed in parallel spaced relation, each said facing extending substantially continuously from the top of the wall panel assembly to the bottom of the assembly, a core of substantially rigid foam insulation material disposed between and contacting said inner and outer facings, a layer of adhesive bonding substantially the entire contacting surface of each said facing to the corresponding side of said core to form a laminated wall unit having a horizontal length greater than its vertical height, a plurality of horizontally spaced vertical wood furring strips positioned adjacent said inner facing and projecting inwardly towards the interior of the building structure, a layer of adhesive rigidly bonding substantially the entire contacting surface of each said furring strip to said inner facing, said furring strips being adapted to receive inner sheeting material to form an interior wall surface for the building structure, means defining at least one channel within each of said furring strips and extending inwardly from the surface contacting said inner facing, and said channels cooperate with said inner facing to define corresponding passages for installing electrical wiring along said inner facing.

5. A composite wall panel assembly adapted to simplify the construction of a building structure, comprising an inner facing of wood sheet material and an outer facing of wood sheet material disposed in parallel spaced relation, each said facing extending substantially continuously from the top of the wall panel assembly to the bottom of the assembly, a core of substantially rigid foam insulation material disposed between and contacting said inner and outer facings, a layer of adhesive bonding substantially the entire contacting surface of each said facing to the corresponding side of said core to form a laminated wall unit having a horizontal length greater than its vertical height, a plurality of horizontally spaced vertical wood furring strips positioned adjacent said inner facing and projecting inwardly towards the interior of the building structure, a layer of adhesive rigidly bonding substantially the entire contacting surface of each said furring strip to said inner facing, said furring strips being adapted to receive inner sheeting material to form an interior wall surface for the building structure, a horizontal beam member disposed between said inner and outer facings at an elevation adjacent the top of a door or window opening formed within said wall unit, said beam member extending from substantially one end of the wall unit to the opposite end, and a layer of adhesive bonding said beam member to said inner facing for transferring a load supported by said wall panel assembly through said inner facing to the bottom of the assembly.
