Abstract

A pocketformer apparatus for a post-tension anchor system including a tubular member with an outwardly flanged end, a securement member affixed to the tubular member, and a cup member having an interior opening such that the tubular member extends through the interior opening. The tubular member has an interior passageway extending from the flanged end to another end. The flanged end engages an anchor of the post-tension anchor system. The cup member is interposed between the flanged end and the securement member on the tubular member. The tubular member has an externally threaded area extending inwardly of the end opposite the flanged end. The securement member is threadedly received by the externally threaded area. An annular ring is formed on the flanged end of the tubular member so as to engage a receptacle formed on the anchor. The securement member, the cup member and the tubular member are formed of polymeric material.

Claims

1. A pocketformer apparatus for a post-tension anchor system comprising:

a tubular member having an outwardly flanged end, said tubular member having an interior passageway extending from said flanged end to another end, said flanged end having means thereon for snap-fit engagement with an anchor of the post-tension anchor system, said means for engagement comprising a slide surface formed on a periphery of said flanged end, said slide surface having a latch member at an end thereof said slide surface having an abutment portion at an end opposite said latch member;

a securement member affixed to said tubular member; and

a cup member having an interior opening, said tubular member extending through said interior opening, said cup member interposed between said flanged end and said securement member on said tubular member.

2. The apparatus of claim 1, said tubular member having an externally threaded area extending inwardly of said another end, said securement member being fixed in position on said externally threaded area.

3. The apparatus of claim 2, said securement member having an interior bore, said interior bore having a thread section formed therein, said thread section in said interior bore engaging said externally threaded area of said tubular member.

4. The apparatus of claim 2, said securement member slidable on said externally threaded area so as to draw said flanged end toward a face of said cup member, said securement member being rotatable so as to be fixed in position on said tubular member.

5. The apparatus of claim 1, said securement member having an abutment surface facing said flanged end.

6. The apparatus of claim 1, said latch member having a spearhead shape, said slide surface extending circumferentially around a portion of said flanged end, said spearhead shape of said latch member having a wide end facing said abutment portion.

9. The apparatus of claim 1, said tubular member, said securement member and said cup member being formed of a polymeric material.

7. A pocketformer apparatus for a post-tension anchor system comprising:

a tubular member having an outwardly flanged end, said tubular member having an interior passageway extending from said flanged end to another end, said flanged end having means thereon for snap-fit engagement with an anchor of the post-tension anchor system;

a securement member affixed to said tubular member; and

a cup member having an interior opening, said tubular member extending through said interior opening, said cup member interposed between said flanged end and said securement member on said tubular member, said cup member having a double oval shape, said cup member having a face at a narrow end of said double oval shape, said face being proximal said flanged end.

8. The apparatus of claim 7, said cup member having a wide end distal said flanged end, said wide end being open with a planar edge.

10. The apparatus of claim 7, said interior opening being a tubular section opening at one end on said face, said tubular section opening at an opposite end at said wide end of said cup member, said tubular section having a diameter greater than a diameter of said tubular member.

11. The apparatus of claim 10, said interior opening offset from a center of said face of said cup member.

12. A post-tension anchorage system comprising:

an anchor member;

a tendon extending through an interior of said anchor member;

a tubular member having a flanged end, said flanged end being removably affixed in snap-fit engagement with said anchor member, said tendon extending through an interior of said tubular member said flanged end having a receptacle means formed thereon, said receptacle means for detachably receiving a button member formed on said anchor member;

a cup member with an interior opening, said tubular member extending through said interior opening; and

a securement member affixed to said tubular member such that said cup member is interposed between said anchor member and said securement member.

13. The system of claim 12, further comprising:

a form board having a hole extending therethrough, said tubular member extending through said hole, said form board interposed between said cup member and said securement member.

14. The system of claim 13, said cup member having a double oval shape, said cup member having a face at a narrow end in contact with said anchor member, said cup member having a wide end in surface-to-surface contact with a surface of said form board.

15. The system of claim 14, said securement member being threadedly affixed to said tubular member, said securement member rotatable so as to fix a position of said securement against said form board.

16. The system of claim 12, said anchor member being covered with a polymeric encapsulation, said encapsulation having a tubular section formed adjacent an end of said anchor member, said button member being formed inwardly of said tubular section, said flanged end affixed within said tubular section.

17. The system of claim 16, said receptacle means comprising:

a slide surface formed on a circumference of said flanged end;

a latch member formed at an end of said slide surface; and

an abutment portion formed at an opposite end of said slide surface, said button member being positioned against said slide surface and said abutment portion when said flanged end is in snap-fit engagement within said tubular section.

18. The system of claim 17, said latch member having a spearhead shape, a wide end of said spearhead shape abutting a surface of said button member opposite said abutment portion.

19. The system of claim 16, said anchor member having a compressible seal member positioned within said polymeric encapsulation at said tubular section, said flanged end being in contact with said compressible seal when said flanged end is in snap-fit engagement with said anchor member.

20. The system of claim 12, said tubular member having an externally threaded area, said securement member being threadedly received by said externally threaded area.

21. The system of claim 20, said externally threaded area of said tubular member having threads with a split formed therebetween, said securement member having an internal thread section formed therein, said internal thread section having a length less than a length of said split.

22. The system of claim 21, said externally threaded area comprising a plurality of parallel threads extending along a portion of the length of said tubular member, said split extending along said portion of said length.
