Abstract
Abstract A concrete skirting system for a prefabricated structure, such as a modular prefabricated home, comprises a plurality of rectangular precast concrete skirt modules. Each module consists of a rectangular panel extended upward from an integral footing. The panel is of thin, reinforced concrete construction with integral ribs on the inner panel surface which faces into the crawl space beneath the structure. The modules are provided with rabbeted side edges which form a rabbet joint when adjacent modules are installed beneath the lower peripheral edge of the structure. A concrete mold is provided to produce the precast modules.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
123 words
A modular load bearable skirting system for pre-manufactured homes and building structures supported in an elevated position which comprises a plurality of rectangular concrete skirt modules positioned in side-by-side adjancy beneath and in contact with the lower peripheral edge of such a building structure; each module having a length greater than its height, and thin panel making up most of its size with a top edge abutting the overhead building structure lower peripheral edge, and a footing integral with and thicker than the panel supporting the module, the side edges of each panel being rabetted so as to provide an inner vertical flange on one edge and outer vertical flange on its other edge with adjacent panel edges abutting in vertical rabbet joints.
Claim 2
Dependent Claim
