Abstract
Abstract A system of constructing buildings by connecting together expanded plastic panels with reinforcing strips bonded thereto and wire mesh attached to the exterior surfaces thereof upon a foundation with at least a portion of the panels having a curved configuration to maximize structural strength of the combination of panels. Concrete is applied to the exterior of the combined panels with the wire mesh then forming reinforcing in the resultant concrete wall upon the panels and the interior is coated with plaster to form a low cost structure with very good insulating properties.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
A method of building fabrication comprising the steps of (a) attaching together a plurality of expanded plastic panels with reinforcing strips bonded thereto to form a building shell having integral walls and roof; (b) said panels having wire mesh mounted on the outer faces thereof in offset relation thereto and lacing together the wire mesh of contiguous panels to form a wire mesh covering on said shell; (c) applying wet concrete to the exterior of said shell on said mesh to form an integral concrete wall and roof of a building with the shell attached thereto, and (d) applying a plaster coating to the interior of said shell to completely seal said panels between concrete and plaster as an insulating core of the resultant building.
Claim 2
Independent Claim
125 words
A method of building fabrication comprising the steps of (a) attaching together a plurality of expanded plastic panels with reinforcing strips bonded thereto to form a building shell having integral walls and roof; (b) said panels having wire mesh mounted on the outer faces thereof in offset relation thereto and lacing together the wire mesh of contiguous panels to form a wire mesh covering on said shell; (c) applying wet concrete to the exterior of said shell on said mesh to form an integral concrete wall and roof of a building with the shell attached thereto, and (d) applying a plaster coating to the interior of said shell to completely seal said panels between concrete and plaster as an insulating core of the resultant building.
Claim 3
Dependent Claim
24 words
The method of claim 1 further defined by attaching said panels together by sheet metal screws driven through overlapping reinforcing strips on contiguous panels.
Claim 4
Dependent Claim
64 words
The method of claim 1 further defined by applying said wet concrete to the shell by spraying the concrete onto the shell from the bottom up with the concrete being applied thickest at the bottom of the shell and the concrete having a thickness of the order of a few inches to form upon hardening a rigid integral wall and roof of the building.
Claim 5
Dependent Claim
143 words
An improved building structure comprising a foundation; a building shell mounted on said foundation and formed of a plurality of molded panels of expanded plastic having reinforcing strips on outer and inner faces thereof and attached together by overlapping reinforcing strips, said panels also having wire mesh mounted in offset relation to the outer faces thereof, said panels being disposed in adjacent contacting relationship and joined together to form a substantially continuous expanded plastic unitary shell with said wire mesh being joined together to form a substantially continuous mesh over said shell; a concrete layer covering the outside of said shell with said wire mesh disposed in the concrete to form a single continuous rigid integral building wall and roof; and a plaster coating on the interior of said shell completely sealing said panels within the integral wall and roof of the building.
Claim 6
Dependent Claim
143 words
An improved building structure comprising a foundation; a building shell mounted on said foundation and formed of a plurality of molded panels of expanded plastic having reinforcing strips on outer and inner faces thereof and attached together by overlapping reinforcing strips, said panels also having wire mesh mounted in offset relation to the outer faces thereof, said panels being disposed in adjacent contacting relationship and joined together to form a substantially continuous expanded plastic unitary shell with said wire mesh being joined together to form a substantially continuous mesh over said shell; a concrete layer covering the outside of said shell with said wire mesh disposed in the concrete to form a single continuous rigid integral building wall and roof; and a plaster coating on the interior of said shell completely sealing said panels within the integral wall and roof of the building.
Claim 7
Dependent Claim
25 words
The building structure of claim 4 further defined by adjacent panels being joined together by screws extending through overlapping reinforcing strips and into the panels.
