Abstract
Abstract This invention discloses a novel system for anchoring modular housing units which are assembled from pre-fabricated panels at the building site. The wall panels are formed with an offset base portion so that when the wall panels are assembled on the footing provided at the building site a generally continuous ledge around the outer perimeter of the floor plan area for the housing unit is provided. A layer of fill sand is spread throughout the interior floor plan area, and a concrete floor layer is poured on top of the fill sand and extends to the outer perimeter of the floor plan area to cover the top of the continuous ledge and thereby provide an effective anchor for the housing unit. Further structural integrity is provided by connecting reinforcement rods between the concrete floor and the footing.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
169 words
In a housing unit, a prefabricated, unitary wall panel having an upper portion extending above a grade level and delimiting an outer perimeter of a portion of an interior area of said unit and a footing below the grade level and supporting said wall panel, and anchoring means for said wall panel comprising a base wall panel portion offset toward said interior area portion from said upper portion of said wall panel for forming a ledge at said perimeter of said interior area portion, a layer of concrete spaced from said footing and extending over said ledge for anchoring said wall panel with said layer and over said interior area portion for forming a part of a floor of said unit, and at least one locking member connected to said base portion of said wall panel and extending from said wall panel and above said ledge into said layer of concrete for locking said wall panel and said layer against separation in a direction normal to said wall panel.
Claim 2
Dependent Claim
169 words
In a housing unit, a prefabricated, unitary wall panel having an upper portion extending above a grade level and delimiting an outer perimeter of a portion of an interior area of said unit and a footing below the grade level and supporting said wall panel, and anchoring means for said wall panel comprising a base wall panel portion offset toward said interior area portion from said upper portion of said wall panel for forming a ledge at said perimeter of said interior area portion, a layer of concrete spaced from said footing and extending over said ledge for anchoring said wall panel with said layer and over said interior area portion for forming a part of a floor of said unit, and at least one locking member connected to said base portion of said wall panel and extending from said wall panel and above said ledge into said layer of concrete for locking said wall panel and said layer against separation in a direction normal to said wall panel.
Claim 3
Dependent Claim
55 words
A system as in claim 1 wherein said layer is spaced from said footing by said base portion of said wall panel and comprising means additional to said wall panel extending between said floor part of said layer and said footing and tying said layer to said footing for anchoring said layer to said footing.
Claim 4
Dependent Claim
182 words
In a housing unit having a prefabricated, unitary wall panel having an upper portion extending above a grade level and delimiting an outer perimeter of a portion of an interior area of said unit and a footing below said grade level and supporting said wall panel, a system for anchoring said wall panel comprising: a base wall panel portion offset toward said interior area portion from said upper portion of said wall panel for forming a ledge at said perimeter of said interior area portion delimited by said wall panel; a layer of concrete spaced from said footing by said base wall panel portion and having a portion extending over said ledge for anchoring said wall panel with said layer and a portion extending over said interior area portion for forming a part of a floor of said unit; and plate means connected to said base portion of said wall panel and extending parallel to said wall panel and above said ledge into said layer for locking said panel and said layer against separation in a direction normal to said wall panel.
Claim 5
Dependent Claim
182 words
In a housing unit having a prefabricated, unitary wall panel having an upper portion extending above a grade level and delimiting an outer perimeter of a portion of an interior area of said unit and a footing below said grade level and supporting said wall panel, a system for anchoring said wall panel comprising: a base wall panel portion offset toward said interior area portion from said upper portion of said wall panel for forming a ledge at said perimeter of said interior area portion delimited by said wall panel; a layer of concrete spaced from said footing by said base wall panel portion and having a portion extending over said ledge for anchoring said wall panel with said layer and a portion extending over said interior area portion for forming a part of a floor of said unit; and plate means connected to said base portion of said wall panel and extending parallel to said wall panel and above said ledge into said layer for locking said panel and said layer against separation in a direction normal to said wall panel.
