A pipe-supporting clamp is disclosed in several embodiments adapted to be permanently embedded in the masonry floor of a building structure for supporting a pipe extending through the center of the clamp. The device has anchor means formed therewith which are surrounded by the masonry material to prevent movement of the device in the floor. A means is also provided adjacent one end of the device for forcing a portion of the interior wall of the device into engagement substantially all around the circumference of a portion of the pipe to clamp the pipe against movement within the device.

A tubularly-shaped pipe-supporting clamp for being embedded in an initially form-sustained floor of a building structure molded of masonry material, said clamp being fixedly attached to a surface of said form prior to introduction of said masonary material into said form so as not to move when said masonary material is introduced into said form and extending upwardly therefrom, to produce a pipe passageway through said molded floor at a particular position, said tubularly shaped pipe supporting clamp comprising: (a) a substantially rigid sleeve having at least an inner surface defining a tubular wall through which a pipe to be clamped passes and an outer surface, (b) flange means at one end of said sleeve for attaching said device to said form, (c) anchor means formed in said outer surface of said sleeve for preventing axial movement of said device in said masonry floor after it has cured, (d) a forcing means for holding said pipe against movement relative to said sleeve, said forcing means including at least one longitudinally-extending slot-shaped recess formed in the inner surface of said wall extending from the other end of said sleeve for a distance substantially greater than half the length of said sleeve, but with the sleeve not having said recess at other longitudinal positions so that the sleeve rather closely encircles said pipe at said other longitudinal positions, said forcing means further including a wedge means longitudinally slidable by longitudinal linear movement in said recess between the inner wall of said sleeve and the outer surface of a pipe when said pipe is in said passageway for simultaneously engaging said pipe and the inner surface of said wall in said slot to wedge therebetween with increasing force as said wedge means is longitudinally slid in said recess to hold said pipe and said wedge against movement in said sleeve, said other end of said sleeve being adapted to be cut off to allow said sleeve to be cut to various lengths ranging from its original length to substantially less than half its original length, whereby when said other end is cut off to an extent substantially greater than half the length of the sleeve there remains a slot shaped recess into which the wedge means can be longitudinally slid.
