Blockout assembly for supporting conduits through concrete panels

A blockout apparatus for installation in a form for constructing a prefabricated concrete Double-T panel with said blockout apparatus being located within a T-beam member, comprising:

• a cylindrical tubular body member having a circumferentially closed configuration between first and second opposing ends defining an interior passageway extending along a longitudinal length dimension between said first and second opposing ends, said tubular body member having an exterior surface, including an exterior surface on an upper portion of said tubular body member, said tubular body member further including an interior surface extending around said passageway;
• at least one dome portion integrally formed with said tubular body member on said upper portion and having a length dimension smaller than said longitudinal length dimension of said interior passageway, said at least one dome member being incorporated integrally into said exterior surface of said upper portion without an opening exposing said interior passageway through said upper portion, said at least one dome portion having an access opening in said interior surface facing said passageway;
• each of said at least one dome portion forming opposing curved hanger members, said hanger members being accessible through said access opening;
• and
• a wedge nut having an enlarged head engaged with said hanger members and including at least one vertically oriented threaded opening facing said passageway, said enlarged head having a width dimension allowing the wedge nut to be inserted into said access opening and a length dimension that engages the hanger members when said wedge nut is rotated for engagement with said hanger members.

A blockout apparatus for installation into a prefabricated concrete structural member to create a passageway therethrough for the passage of conduits and other structural members, comprising:

• a cylindrical tubular body member having a circumferentially closed configuration between first and second opposing ends defining said passageway having a longitudinal length dimension extending between said opposing ends, said tubular body member having an upper portion;
• a pair of dome portions integrally formed with said tubular body member in said upper portion, each of said dome portions being located proximate to one of said opposing ends and having a length dimension smaller than said longitudinal length dimension of said tubular body member, each of said dome portions establishing an integral exterior surface with said upper portion without an opening exposing said interior passageway through said upper portion, each of said dome portions having an access opening facing said passageway;
• and
• each of said dome portions including opposing curved hanger members formed therein and being accessible through said access opening.
