#2. Field of the Present Disclosure

#The accompanying drawings illustrate at least one of the best mode embodiments of the present apparatus and method of it use. In such drawings:

#FIG. 1 is a perspective view of one embodiment of the apparatus, with a flange at each end, as mounted in a concrete form;

#FIG. 2 is a perspective view of a further embodiment of the apparatus as formed within a concrete wall with one end providing a flange and an opposing end without a flange;

#The above described drawing figures illustrate the described apparatus and its method of use in at least one of its preferred, best mode embodiment, which is further defined in detail in the following description. Those having ordinary skill in the art may be able to make alterations and modifications what is described herein without departing from its spirit and scope. Therefore, it must be understood that what is illustrated is set forth only for the purposes of example and that it should not be taken as a limitation in the scope of the present apparatus and method of use.

#The presently described apparatus, in one embodiment, comprises a tubular element fastened between forms erected for pouring a concrete structure such as a wall, a floor or a ceiling and provides a passage for utility conductors such as pipes and conduits, as shown in FIG. 1. In a further embodiment, the tubular element is integral with a structural separator such as a wall, a partition, a floor or a ceiling, as best shown in FIG. 2. In a still further embodiment of the present apparatus, the tubular element is a stand-alone component that may be used as described or in alternative ways without limit as would be known by those of skill in the art. Thus, it should be realized by those of skill that the tubular element described herein may be used in a very wide range of applications where the tubular element is only one component of an apparatus that is necessary to an end objective.

#Therefore, in the first embodiment described above, the apparatus comprises a pair of forms 10 and 10′ set up for defining a poured concrete wall 20 for separating compartments or rooms or spaces, and this embodiment includes a tubular conduit 30 positioned for joining the compartments, as shown in FIG. 1. Such a wall 20 may be used for separating side-by-side adjacent compartments, or compartments arranged one above the other. In either case, the arrangement of components of the conduit 30, as described below, is identical. FIG. 2 shows a wall 20 that is used to separate side-by-side compartments “A” and “B.”
