Abstract
Abstract Building construction from modules of inverted U shape a full story high with a span of 10 to 30 feet and a depth of 2 to 6 feet. The modules may be monolithic such as of reenforced concrete or plastic foam, or may be of light weight hollow metal construction, assembled together with partitions and end panels. Cast modules can be cast between thin previously formed sheets held by framework to form casting mold, the sheets becoming surfaces of the module.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
132 words
A method of making a building module having the shape of an inverted U with legs at least a full story high, a span of about 10 to about 30 feet between the legs, and a depth between about 2 and about 6 feet, which method comprises casting on a plain flat horizontal surface a series of surface panels not over about two inches in thickness, said panels being dimensioned to form the major surgaces of the module, after the case surface panels are sufficiently strong mounting the panels between spaced vertical supports in opposing vertical planes to define an open-ended vertically extending U-shaped cavity, casting setable material in said U-shaped cavity, and when the setable material is sufficiently strong tilting the U-shaped module to inverted U-position for use in a building.
Claim 2
Independent Claim

Claim 3
Dependent Claim
32 words
The combination of claim 1, in which the panels are cast with internal reenforcement, and the reenforcements of mounted opposing panels are tied together before the balance of the module is cast.
