Abstract
Abstract A knockdown building with a floor made up of several panels having a core of insulation material and structural members extending around the periphery of the core made of wood and received between the plywood of the floor panels in which a simple angle iron frame coupled with the strength of the peripheral wooden structural members provides the strength necessary for handling and tailgating a building. The roof is flat and buildings may be stacked directly one upon the other with force transmitted directly through structural members to the angle iron skid. Due to the flat roof, several buildings may be stacked directly one upon the other eliminating the need for stacking racks and due to the simple angle iron skid replacing the massive oil field-type skid of past construction the cube for a building prepared for shipment is drastically reduced.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
241 words
A knockdown building comprising: a rectangular floor comprising a plurality of spaced wooden structural members and upper and lower sheets of structural material secured to the structural members with a lower surface of said lower sheets providing a bottom of said floor; side walls comprising: a plurality of spaced structural members and an inner and outer skin of structural metal secured to the structural members; a roof comprising: a plurality of spaced structural members and an inner and outer skin of structural material secured to the structural members, said outer skin covered with waterproof materials, and a rectangular skid of angle iron members arranged with the interior side of each angle iron member in engagement with the bottom and a side of said floors; said angle iron members secured to said floor and secured to each other at the four corners of the floor with one of the angle iron members extending beyond the rectangular skid at each corner of the floor; and a hole in each extending angle iron member for engagment by a lifting device, said floor, side walls and roof being flat and having no protrusions extending upwardly from the floor, inwardly or outwardly of the walls or upwardly or downwardly from the roof other than said angle iron members; permitting said walls to be stacked on said floor and said roof to be stacked on said walls and buildings to be stacked on each other during shipment.
Claim 2
Dependent Claim
241 words
A knockdown building comprising: a rectangular floor comprising a plurality of spaced wooden structural members and upper and lower sheets of structural material secured to the structural members with a lower surface of said lower sheets providing a bottom of said floor; side walls comprising: a plurality of spaced structural members and an inner and outer skin of structural metal secured to the structural members; a roof comprising: a plurality of spaced structural members and an inner and outer skin of structural material secured to the structural members, said outer skin covered with waterproof materials, and a rectangular skid of angle iron members arranged with the interior side of each angle iron member in engagement with the bottom and a side of said floors; said angle iron members secured to said floor and secured to each other at the four corners of the floor with one of the angle iron members extending beyond the rectangular skid at each corner of the floor; and a hole in each extending angle iron member for engagment by a lifting device, said floor, side walls and roof being flat and having no protrusions extending upwardly from the floor, inwardly or outwardly of the walls or upwardly or downwardly from the roof other than said angle iron members; permitting said walls to be stacked on said floor and said roof to be stacked on said walls and buildings to be stacked on each other during shipment.
Claim 3
Dependent Claim
88 words
The building of claim 1 wherein said floor is constructed of a plurality of panels extending the width of said floor, each panel is provided by at least one structural member and cellular insulation material bonded to the upper and lower sheets to provide structural panels, and at least one of said panel structural members provides splines between adjacent panels, said structural members including members received between said upper and lower sheets of said panels and extending about the periphery of said floor to secure said panels together.
Claim 4
Dependent Claim
27 words
The building of claim 2 wherein said peripheral structural members extending between panels are provided by parallel structural members with offset overlapping ends secured to each other.
Claim 5
Dependent Claim
85 words
The building of claim 1 wherein the walls have approximately the same height dimension as the width of the floor and roof and each of the floor, walls and roof have structural members extending about their periphery, said walls when laid down over said floor and said roof when supported on laid down walls having structural members overlying at least some of the peripheral structural members of the floor to transmit the load of the walls and roof to the skid through the structural members.
Claim 6
Dependent Claim
68 words
The building of claim 1 wherein said floor is made up of a plurality of panels, said panels each comprising spaced sheets of plywood with expanding cellular insulation material bonded therebetween, a spline provided by a structural member is secured between said spaced sheets of adjacent panels, and structural members extending about the periphery of the floor and positioned between and secured to the spaced sheets of plywood.
Claim 7
Dependent Claim
28 words
The building of claim 1 wherein said structural members extending about the periphery of the floor are approximately three and one-half by three and one-half inch in cross-section.
Claim 8
Dependent Claim
46 words
The building of claim 1 wherein each of the floor, walls and roof include structural members about their periphery and spaced structural members between peripheral structural members all secured to the structural material on each side of the structural members to provide rigid load supporting structures.
