Pocketformer assembly for a post-tension anchor system
View Patent ↗A pocketformer apparatus for post-tension construction has an anchor member with an interior passageway, a tubular member extending into the interior passageway, a cup member with an interior opening in which the tubular member extends through the interior opening, and a securement member affixed adjacent the opposite end of the tubular member from the anchor body. The interior passageway has a threaded portion. The tubular member has a first end retained in the threaded portion. The tubular member has the second end extending outwardly of a side of the anchor body opposite the threaded portion. The cup member is interposed between the securement member and the anchor member. A form board is interposed between the cup member and the securement member. The threaded portion is an internal thread formed on an non-tapered portion of the interior passageway.
1. A pocketformer apparatus for post-tension construction comprising:
a one piece anchor body having a cavity formed therein, said cavity defining an interior passageway through said anchor body, said cavity having a tapered portion with a wide diameter end at one side of said anchor body and a narrow diameter end inwardly therefrom, said cavity having a non-tapered portion extending from said narrow diameter end of said tapered portion to an opposite side of said anchor body, said non-tapered portion having threads formed thereon;
a tubular member having a portion extending into said cavity of said anchor body, said tubular member having threads formed at a first end thereof, said threads of said tubular member being only engaged with said threads of said non-tapered portion of said cavity, said first end of said tubular member extending only to said opposite side of said anchor body, said tubular member having a second end extending outwardly of said one side of said anchor body;
a cup member having an interior opening, said tubular member extending through said interior opening, said cup member having a wide end and an narrow end; and
a securement member affixed adjacent said second end of said tubular member, said cup member interposed between said securement member and said anchor body.
2. The pocketformer apparatus of claim 1 , further comprising:
a tendon extending through said interior passageway of said anchor body and through said tubular member.
3. The pocketformer apparatus of claim 2 , said tubular member interposed between said tendon and a wall of said interior passageway of said anchor body, said tubular member interposed between said tendon and a wall of said interior opening of said cup member.
4. The pocketformer apparatus of claim 2 , said tendon having a sheathing extending thereover.
5. The pocketformer apparatus of claim 1 , said tubular member having a tapered outer diameter juxtaposed against a wall of said tapered portion of said cavity of said anchor body.
6. The pocketformer apparatus of claim 1 , said threads of said tubular member being external threads, said external threads being threadedly engaged with said threads of said non-tapered portion of said cavity.
7. The pocketformer apparatus of claim 1 , further comprising:
a form board interposed between said cup member and said securement member, said form board having a hole formed therein, said tubular member extending through said hole.
8. The pocketformer apparatus of claim 1 , said narrow end of said cup member having positioning elements extending longitudinally outwardly therefrom transverse to a plane of an end surface at said narrow end, said anchor body received between said positioning elements such that said interior passageway of said anchor body is in axial alignment with said interior opening of said cup member.
