Claim 10

The method as set forth in clami 6 wherein said unitary member further comprises stop means integrally formed with said wall for preventing rotational movement about the longitudinal axis of said member in said masonry floor after it has cured.

Claim 11

The method as set forth in clami 6 wherein said unitary member further comprises stop means integrally formed with said wall for preventing rotational movement about the longitudinal axis of said member in said masonry floor after it has cured.

Claim 12

A device adopted to be embedded in an at least initially form-supported masonry floor of a building structure for supporting piping extending therethrough, said device comprising: (a) a substantially rigid member including a tubular portion having inner and outer surfaces defining a continuous wall, said outer surface having circumferentially extending spaced-apart grooves for preventing the passage of fluid between said wall and said masonry floor and a flange means integral with one end of said tubular portion for attaching said device to said form, said flange means having a plurality of spaced-apart grooves on a face thereof for engaging said form to prevent the passage of fluid therebetween, (b) anchor means integrally formed with tubular portion for preventing axial movement of said device in said masonry floor after it has cured, and (c) groove means formed on said inner surface at least adjacent the other end of said tubular portion for holding a quantity of plastic cement to bond said piping to said inner surface.

Claim 13

A device adopted to be embedded in an at least initially form-supported masonry floor of a building structure for supporting piping extending therethrough, said device comprising: (a) a substantially rigid member including a tubular portion having inner and outer surfaces defining a continuous wall, said outer surface having circumferentially extending spaced-apart grooves for preventing the passage of fluid between said wall and said masonry floor and a flange means integral with one end of said tubular portion for attaching said device to said form, said flange means having a plurality of spaced-apart grooves on a face thereof for engaging said form to prevent the passage of fluid therebetween, (b) anchor means integrally formed with tubular portion for preventing axial movement of said device in said masonry floor after it has cured, and (c) groove means formed on said inner surface at least adjacent the other end of said tubular portion for holding a quantity of plastic cement to bond said piping to said inner surface.

Claim 16

A device adapted to be embedded in an at least initially form- supported masonry floor of a building structure for supporting piping extending therethrough, said device comprising: (a) a substantially rigid unitary member including a tubular portion having inner and outer surfaces defining a continuous wall, said outer surface having circumferentially extending, spaced-apart grooves for preventing the passage of fluid between said wall and said masonry floor, and a flange means integral with one end of said tubular portion for attaching said device to said form, said flange means having a plurality of spaced-apart grooves on a face thereof for engaging said form to prevent the passage of fluid therebetween, (b) anchor means integrally formed with said tubular portion for preventing axial movement of said device in said masonry floor after it has cured, and (c) grip means integrally formed on said inner surface for engaging said piping and holding same against movement relative to the longitudinal axis as said tubular portion.
