Abstract
Abstract A house erected with preassembled frames, with each frame including a floor truss system, trussed rafter system, and conventional wall studs, which are integrally joined together into a rigid framework capable of supporting loads over long spans without intermediate supports. Each of the components resists imposed loads applied at any point in the frame. The preassembled frames are individually tilted up onto the sill plates at the construction site. Successive frames are erected and structural sheathing is attached thereto until the structure is completed. The structural superiority of the integral truss assembly, both in strength and stiffness, is amenable by structural analysis.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
139 words
A building, comprising a plurality of sill plates installed on a foundation, a plurality of frames disposed in parallel vertical planes normal to the plane of said sill plates, each frame comprising a floor truss system, wall studs connected to the ends of said system and extending upward therefrom, and a roof truss extending between and connected to the upper ends of said studs, said floor truss system, comprising a top floor chord and bottom floor chord, parallel with one another, which extend between and connect at their ends to said studs, with said bottom floor chord being adjacent to said studs' lower ends, with web members extending between and connected to said chords, means connecting said frames to said sill plates, means securely anchoring said frames in proper vertical orientation, said last-mentioned means running perpendicular to said frames.
Claim 2
Dependent Claim
139 words
A building, comprising a plurality of sill plates installed on a foundation, a plurality of frames disposed in parallel vertical planes normal to the plane of said sill plates, each frame comprising a floor truss system, wall studs connected to the ends of said system and extending upward therefrom, and a roof truss extending between and connected to the upper ends of said studs, said floor truss system, comprising a top floor chord and bottom floor chord, parallel with one another, which extend between and connect at their ends to said studs, with said bottom floor chord being adjacent to said studs' lower ends, with web members extending between and connected to said chords, means connecting said frames to said sill plates, means securely anchoring said frames in proper vertical orientation, said last-mentioned means running perpendicular to said frames.
Claim 3
Dependent Claim
64 words
The invention set forth in claim 1 wherein each of said studs extends upward from said bottom floor chord to one of the joints between the top roof chords and bottom roof chord, with said stud being connected to said joint and connected at a lower point to a lookout which extends between said stud and the overhanging end of said top roof chord.
Claim 4
Dependent Claim
57 words
The invention set forth in claim 2 wherein said roof truss system comprises a bottom roof chord extending between ends of said studs, being parallel to the floor chords, with angularly interconnected top roof chords, and web members extending between and connected to said top and bottom roof chords, with all connections being secured by rigid fasteners.
Claim 5
Dependent Claim
37 words
The invention set forth in claim 1 wherein intermediate stiffeners extend between and connect to the top floor chord and bottom flood chord, and wherein the web members are attached to each side of the stiffener-chord configuration.
Claim 6
Dependent Claim
106 words
A flat structural building frame to be used as a vertical component of a framing system, comprised of a floor system, wall studs connected to the ends of said system and extending upward therefrom, a roof truss system a roof truss system extending between the connected to the upper ends of said studs, and wherein said floor truss system comprises a top floor chord and a cottom floor chord, parallel with one another, which extend between and connect at their ends to said studs, with said bottom floor chord being adjacent to said studs' lower ends, with web members extending between and connected to said chords.
Claim 7
Dependent Claim
106 words
A flat structural building frame to be used as a vertical component of a framing system, comprised of a floor system, wall studs connected to the ends of said system and extending upward therefrom, a roof truss system a roof truss system extending between the connected to the upper ends of said studs, and wherein said floor truss system comprises a top floor chord and a cottom floor chord, parallel with one another, which extend between and connect at their ends to said studs, with said bottom floor chord being adjacent to said studs' lower ends, with web members extending between and connected to said chords.
Claim 8
Dependent Claim
64 words
The invention set forth in claim 5 wherein each of said studs extends upward from said bottom floor chord to one of the joints between the top roof chords and bottom roof chord, with said stud being connected to said joint and connected at a lower point to a lookout which extends between said stud and the overhanging end of said top roof chord.
