Abstract
Abstract A building construction system provides a building wherein the entire building acts as a structural unit and the system comprises a plurality of connected floor panels each having edge portions thereof supported on spaced support members and a plurality of connected wall panels each having one edge thereof supported on the floor panels and extending upwardly therefrom with a plurality of connected ceiling panels supported on the wall panels. The floor, wall, and ceiling panels each are of laminated or sandwich construction and include a pair of generally parallel face members separated by an insulating core member. Adjacent edges of the floor, wall, and ceiling panels are secured together by a spline member placed between the face members of each of the adjacent panels to be secured together and fastening members extending through the face members of each panel and the spline member.

Total Claims: 8
Claim 1
Independent Claim
313 words
A building structure comprising: a. a plurality of connected walls; b. a plurality of generally rectangular panels in each of said walls; c. each of said panels being of laminated construction and having outer layers of plywood in parallel relation and spaced laterally of each other; d. an inner layer of rigid synthetic resin foam between said outer lAyers with the adjacent surfaces of the inner layer and outer layers bonded together, the thickness of the laminated panel being the wall thickness; e. said panel having a thickness in the nature of 3 3/4 inches with the total thickness of plywood being greater than the thickness of the inner layer with each of said panels being of a load bearing structure; f. a panel in one wall having a groove in a portion of an outer layer, said outer layer being engaged on each side of said groove by edges of outer layers of an adjacent panel in a second wall connected thereto; g. said inner layer of each panel having side and end edges spaced inwardly of the respective side and end edges of the outer layers; h. wood members filling the space between the outer layers of one panel at adjacent edges of panels of a wall and having a projecting portion engaged between outer layers of a next panel with said wood member bonded to the panels by adhesive; i. fastening means extending through certain outer layers and into the wood member to further secure the panels together in a keyed, bonded relation whereby the entire building acts as a structural unit; j. a wood member filling the space between the outer layers of said adjacent panel of the second wall at the edges engaging the panel of said one wall and having a projecting portion engaged in said groove with said wood member bonded to the panels by adhesive.

313 words
A building structure comprising: a. a plurality of connected walls; b. a plurality of generally rectangular panels in each of said walls; c. each of said panels being of laminated construction and having outer layers of plywood in parallel relation and spaced laterally of each other; d. an inner layer of rigid synthetic resin foam between said outer lAyers with the adjacent surfaces of the inner layer and outer layers bonded together, the thickness of the laminated panel being the wall thickness; e. said panel having a thickness in the nature of 3 3/4 inches with the total thickness of plywood being greater than the thickness of the inner layer with each of said panels being of a load bearing structure; f. a panel in one wall having a groove in a portion of an outer layer, said outer layer being engaged on each side of said groove by edges of outer layers of an adjacent panel in a second wall connected thereto; g. said inner layer of each panel having side and end edges spaced inwardly of the respective side and end edges of the outer layers; h. wood members filling the space between the outer layers of one panel at adjacent edges of panels of a wall and having a projecting portion engaged between outer layers of a next panel with said wood member bonded to the panels by adhesive; i. fastening means extending through certain outer layers and into the wood member to further secure the panels together in a keyed, bonded relation whereby the entire building acts as a structural unit; j. a wood member filling the space between the outer layers of said adjacent panel of the second wall at the edges engaging the panel of said one wall and having a projecting portion engaged in said groove with said wood member bonded to the panels by adhesive.
Claim 3
Dependent Claim
53 words
A building structure as set forth in claim 1 wherein: a. said panels have a thickness in the nature of 3 3/4 inches; b. said outer layers of plywood have a thickness in the nature of 1 inches; and c. said inner layer has a thickness in the nature of 1 1/2 inches.
Claim 4
Dependent Claim
91 words
A building structure as set forth in claim 1 wherein: a. said panels of a wall are in edge to edge relation; b. said wood member is a spline member between edge portions of said outer layers of each of said panels to be keyed together in a wall; and c. said fastening means extend through one of the outer layers of each panel and through said spline member and at least into the other outer layer of each of said panels to thereby key and secure the adjacent panels together.
Claim 5
Dependent Claim
159 words
A building structure as set forth in claim 1 wherein said walls include floors and upright walls and ceilings formed of said laminated panels and including: a. a groove in an upper outer layer of the panels of the floor; b. a lower edge of the upright walls having a recess defined by the spacing of a lower edge portion of said inner layer upwardly of edge portions of said outer layers thereof; c. a wood member being received in said groove of the floor panel and positioned in said recess between edge portions of said outer layers of the panels of the respective upright wall and forming a spline member; d. fastening members extending through said spline member and into at least the outer layer of the panels of the floor having said groove therein; and e. elongate support members under the panels of the floor and having supporting engagement therewith only at ends of said floor panels.
Claim 6
Dependent Claim
136 words
A building structure as set forth in claim 1 wherein said walls include floors and upright walls and ceilings formed of said laminated panels and including: a. a groove in an outer layer of the panels of the ceiling; b. an upper edge of said upright walls having a recess defined by the spacing of an upper edge portion of said inner layer downwardly of edge portions of said outer layers thereof; c. said wood member being received in said groove of the ceiling panel and positioned in said recess between edge portions of said outer layers of the panels of the respective upright wall and forming a spline member; and d. fastening members extending through said spline member and into at least the outer layer of the panels of the ceiling having said groove therein.
Claim 7
Dependent Claim
197 words
A building structure as set forth in claim 1 wherein said walls include floors and upright walls and ceilings formed of said laminated panels and including: a. said panels of each of the upright walls at exterior corners of the building structure having a recess defined by the spacing of an upright edge portion of said inner layer of said corner panels inwardly of edge portions of said outer layers thereof; b. a wood member in each of said recesses between edge portions of said outer layers of the corner panels of each of the upright walls at exterior corners of the building structure, an edge of one wood member engaging a side of the other wood member; c. one outer layer of each corner panel forming an exterior building member and extending beyond the respective wood member to engage the said one outer layer of the other corner panel; d. fastening members securing each wood member in the respective panels and securing the panels to the wood member in the other wall; e. the engaging portions of the wood members and the engaging portions of the outer layers of the panels being secured together with adhesive.
Claim 8
Dependent Claim
57 words
A building structure as set forth in claim 1 wherein said panels are adapted for tongue-and-groove joining with adjacent panels and a certain edge of one of said outer layers has a tongue extending therefrom for substantially the length thereof and the same edge of the other outer layer of said panels having a tongue receiving groove.
