Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 247 words
A building of a type having exterior and interior walls formed of precast vertical panels of a selected width juxtaposed in a manner to provide the outline of the building and its interior partitioning, wherein some of said panels are spaced a panel width from its nearest panel to provide door openings, wherein a number of panels have less vertical height than others to provide window openings and wherein the remainder of said panels are of the same height such that their upper surfaces fall in the same horizontal plane, the improvement comprising, a plurality of linking bars of substantially rectangular configuration having lengths in multiples equal to the widths of said panels and positioned over said panels so that their respective ends are positioned at the mid-width points of said panels, said bars having linking slots at their ends formed by relatively narrow slots leading to enlarged sectors and wherein the adjacent narrow slots form a narrow passageway communicating the enlarged sectors thereof to form a chamber, a reinforcing member having a narrow midportion and enlarged ends for reception as a unit in said chamber, reinforcing bars embedded in said wall panels and having portions extending upwardly beyond the upper surface of said panel, said linking bars having openings intermediate their lengths for the reception of said portions, a precast roof supported by and extending over said linking bars and formed with roof openings disposed in vertical alignment with said intermediate openings of said linking bars.
Claim 2
Dependent Claim 247 words
A building of a type having exterior and interior walls formed of precast vertical panels of a selected width juxtaposed in a manner to provide the outline of the building and its interior partitioning, wherein some of said panels are spaced a panel width from its nearest panel to provide door openings, wherein a number of panels have less vertical height than others to provide window openings and wherein the remainder of said panels are of the same height such that their upper surfaces fall in the same horizontal plane, the improvement comprising, a plurality of linking bars of substantially rectangular configuration having lengths in multiples equal to the widths of said panels and positioned over said panels so that their respective ends are positioned at the mid-width points of said panels, said bars having linking slots at their ends formed by relatively narrow slots leading to enlarged sectors and wherein the adjacent narrow slots form a narrow passageway communicating the enlarged sectors thereof to form a chamber, a reinforcing member having a narrow midportion and enlarged ends for reception as a unit in said chamber, reinforcing bars embedded in said wall panels and having portions extending upwardly beyond the upper surface of said panel, said linking bars having openings intermediate their lengths for the reception of said portions, a precast roof supported by and extending over said linking bars and formed with roof openings disposed in vertical alignment with said intermediate openings of said linking bars.
