Pipe-attachment apparatus (10) for attaching a pipe (22) to a concrete-form wall (16) includes a first attachment device (12,44,56) to be attached to the concrete-form wall and a second-attachment device (14,58) having a radially directed surface for contacting a surface of the pipe and thereby helping to support the pipe. One of the first or second attachment devices includes an axially-extending protrusion (30,70) and the other includes an axially-extending cavity (24,62) for slidably receiving the protrusion. With this arrangement, the second attachment device aids in supporting the pipe from the concrete-form wall during the pouring of concrete, but after the concrete has cured, the first and second attachment devices easily slide away from one another leaving the first attachment device on the concrete form wall and the second attachment device on the pip. In one embodiment a single size first attachment device (80) can be used with a plurality of sizes of second attachment devices (82A and B) for handling different size pipe (98A and B).

Pipe-attachment apparatus for attaching an elongated pipe to a concrete form wall, with an axis of said pipe extending laterally away from said form wall, said apparatus including: a first attachment means for being attached to said concrete form wall and extending axially away from said form wall, laterally to said form wall, said first attachment means having an outwardly, radially directed, outer surface for helping to support said pipe on said concrete form wall; a second attachment means separate from said first attachment means and said pipe, said second attachment means defining a radially outwardly directed surface for tightly contacting a radially inwardly directed, internal surface of said pipe to have frictional engagement therewith, thereby helping to support said pipe on said concrete form wall, said second attachment means contacting only said radially inwardly directed internal surface of said pipe, said second attachment means radially outwardly directed surface being tapered radially inwardly away from said concrete form wall when said second attachment means is mounted on said first attachment means, said second attachment means defining a cavity extending axially, laterally away from said concrete form wall for substantially completely receiving said first attachment means, said cavity defining a radially inwardly directed surface corresponding to said radially outwardly directed outer surface of said first attachment means; said radially outwardly directed outer surface of said first attachment means and said radially inwardly directed cavity surface of said second attachment means being of approximately the same size for fitting tightly together but allowing sliding axial movement between them without damaging either member; means for attaching said first attachment means to said concrete form wall to permit sliding axial movement between said first attachment means and said cavity surface thereby aiding in supporting said pipe on said concrete form wall during a pouring of concrete, but after the concrete is cured allowing the form wall to be removed in an axial direction with said first and second attachment means sliding away from one another leaving the first attachment means on the concrete-form wall and the second attachment means on said pipe.
