Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
129 words
A fabricated floor drain for waste reception comprising: a receptor body having an outwardly extending top rim extending around the top thereof, side walls and a bottom outlet; flange means sealingly affixed about the entire exterior of the side walls of the receptor body just above the point at which said flange means meets the wall; and membrane clamp means held against the under surface of the top rim, said membrane clamp means having two ends, the first end having at least one clamp bar which abuts the upper surface of membrane to be held against the flat shelf portion of the flange means and the second end of the clamp means being held against the under surface of the top rim and not protruding above said top rim.
