Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
229 words
For use in the construction of a building, a combined decking and ceiling forming member, said member being of a precast concrete construction and including an upper slab defining portion and at least one integral depending beam portion, said beam portion having a lower exposed ceiling forming portion being of greater width than the adjacent portion of the remainder of said beam portion and projecting to one side of the remainder of said beam portion to define a ceiling panel supporting ledge, a ceiling panel receiving notch formed in the opposite side of said beam portion for cooperation with a ledge of a like beam portion to support a ceiling panel, said combined decking and ceiling member being of a dimension for supporting a ceiling panel of a predetermined width, the spacing between the bottom of said notch and the adjacent beam portion bearing said cooperating ledge being greater than said predetermined width for facilitating installation of said panel, and the spacing between the bottom of said notch and the nearest edge of said cooperating ledge being less than said predetermined width for preventing accidental release of a shifted ceiling panel, and said beam portion being free of overlying relation with respect to said panel supporting ledge in the vicinity of said ledge facilitating tilting of a ceiling panel to effect removal thereof from said ceiling panel receiving notch.
