Abstract
Abstract Building components are disclosed which are constructed at a factory and assembled on site. The components include walls employing concrete reinforced steel columns attached to lightweight insulation. The insulation is secured to the columns by use of a wire mesh disposed between columns. Concrete reinforced steel headers are also provided. A roof includes sheet metal decking provided with lightweight insulation and reinforced for rigidity.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
147 words
A prefabricated wall unit for use in building construction comprising: (a) at least two elongated concrete reinforced support columns, said columns being in spaced parallel relation and each defining a compartment adapted to receive said concrete reinforcement, said columns further including means for joining adjacent wall units together, (b) a wire mesh disposed between said columns in the plane defined by said columns, the ends of said mesh being embedded in the concrete, (c) foam insulating material molded to the wire mesh and filling substantially the entire space between said columns to a thickness of at least approximately the thickness of said columns, said insulation being rigid and lightweight, (d) said unit including additional support columns located intermediate the first two columns, and a metal frame structure attached to said additional columns, said frame permitting the field installation of windows and doors by attachment to said frame.
Claim 2
Dependent Claim
147 words
A prefabricated wall unit for use in building construction comprising: (a) at least two elongated concrete reinforced support columns, said columns being in spaced parallel relation and each defining a compartment adapted to receive said concrete reinforcement, said columns further including means for joining adjacent wall units together, (b) a wire mesh disposed between said columns in the plane defined by said columns, the ends of said mesh being embedded in the concrete, (c) foam insulating material molded to the wire mesh and filling substantially the entire space between said columns to a thickness of at least approximately the thickness of said columns, said insulation being rigid and lightweight, (d) said unit including additional support columns located intermediate the first two columns, and a metal frame structure attached to said additional columns, said frame permitting the field installation of windows and doors by attachment to said frame.
Claim 3
Dependent Claim
50 words
The wall unit according to claim 1 wherein said support columns are formed of sheet metal and said joining means includes a flange portion on each of said columns extending above the level of the concrete reinforcement, said flanges being secured one to the other to join adjacent wall units.
Claim 4
Dependent Claim
137 words
A prefabricated wall unit for use in building construction comprising: (a) at least two elongated concrete reinforced support columns, said columns being in spaced parallel relation and each defining a compartment adapted to receive said concrete reinforcement, said columns further including means for joining adjacent wall units together, (b) a wire mesh disposed between said columns in the plane defined by said columns, the ends of said mesh being embedded in the concrete, (c) foam insulating material molded to the wire mesh and filling substantially the entire space between said columns to a thickness of at least approximately the thickness of said columns, said insulation being rigid and lightweight, said wire mesh and foam insulation terminate at a point above the bottom of said columns, said columns being secured in a building foundation at the construction site.
Claim 5
Dependent Claim
137 words
A prefabricated wall unit for use in building construction comprising: (a) at least two elongated concrete reinforced support columns, said columns being in spaced parallel relation and each defining a compartment adapted to receive said concrete reinforcement, said columns further including means for joining adjacent wall units together, (b) a wire mesh disposed between said columns in the plane defined by said columns, the ends of said mesh being embedded in the concrete, (c) foam insulating material molded to the wire mesh and filling substantially the entire space between said columns to a thickness of at least approximately the thickness of said columns, said insulation being rigid and lightweight, said wire mesh and foam insulation terminate at a point above the bottom of said columns, said columns being secured in a building foundation at the construction site.
Claim 6
Dependent Claim
18 words
The wall unit according to claim 1 wherein said foam is selected from the group comprising: polyurethane, styrene.
Claim 7
Independent Claim
129 words
A method of fabricating wall units for construction of a site assembled building comprising the steps of: (a) positioning at least two elongated support columns horizontally in spaced parallel relation, each of said columns defining a compartment for receiving concrete to reinforce said columns, (b) pouring concrete into said column compartments, (c) positioning a wire mesh between said columns in the plane defined by said columns, the ends of said mesh being embedded into said concrete before the latter hardens, (d) molding foam insulating material to said wire mesh to substantially fill the entire space between said columns, (e) said wire mesh and foam insulation terminate at a point above the bottom of said column whereby the columns can be secured in a building foundation at a construction site.
Claim 8
Independent Claim
129 words
A method of fabricating wall units for construction of a site assembled building comprising the steps of: (a) positioning at least two elongated support columns horizontally in spaced parallel relation, each of said columns defining a compartment for receiving concrete to reinforce said columns, (b) pouring concrete into said column compartments, (c) positioning a wire mesh between said columns in the plane defined by said columns, the ends of said mesh being embedded into said concrete before the latter hardens, (d) molding foam insulating material to said wire mesh to substantially fill the entire space between said columns, (e) said wire mesh and foam insulation terminate at a point above the bottom of said column whereby the columns can be secured in a building foundation at a construction site.
Claim 9
Dependent Claim
44 words
The method according to claim 5 further including the steps of: (e) positioning additional support columns intermediate the first two columns, (f) attaching a metal frame to said additional columns for permitting subsequent field installation of windows and doors by attachment to said frame.
Claim 10
Dependent Claim
59 words
A prefabricated building suitable for shipment to and subsequent erection at a building site comprising: (a) wall units formed from concrete reinforced metal columns having rigid foam secured therebetween on a wire mesh frame, (b) concrete reinforced metal header columms attached to the top of said wall units, (c) insulated roof panels attached to and supported on said headers.
Claim 11
Dependent Claim
59 words
A prefabricated building suitable for shipment to and subsequent erection at a building site comprising: (a) wall units formed from concrete reinforced metal columns having rigid foam secured therebetween on a wire mesh frame, (b) concrete reinforced metal header columms attached to the top of said wall units, (c) insulated roof panels attached to and supported on said headers.
Claim 12
Dependent Claim
38 words
The building according to claim 7 wherein said roof panels comprise: (a) pairs of opposed, elongated, C-shaped metal brackets, (b) metal decking secured to one side of said brackets, (c) insulation disposed in the space between said brackets.
