Abstract

A pocketformer apparatus for post-tension construction including an anchor member having a wedge-receiving cavity therein, a tubular member having a portion extending through the wedge-receiving cavity, a first securement member affixed to a first end of the tubular member, a cup member positioned over the tubular member, and a second securement member affixed to a second end of the tubular member. The cup member is interposed between the second securement member and the anchor member. The tubular member also extends through a hole in a form board. The second securement member is positioned on one side of the form board. The cup member and the anchor member are positioned on an opposite side of the form board. A tendon extends through the tubular member.

Claims

1. A pocketformer apparatus for post-tension construction comprising:

an anchor member having a wedge-receiving cavity formed therein;

a tubular member having a portion extending through said wedge-receiving cavity, said tubular member having a first end extending outwardly of one side of said anchor member, said tubular member having a second end extending outwardly from an opposite side of said anchor member;

a first securement member threadedly affixed to said first end of said tubular member;

a cup member having an interior opening, said tubular member extending through said interior opening, said cup member having a wide end and a narrow end, 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 member received between said positioning elements such that said wedge-receiving cavity is in axial alignment with said interior opening of said cup member; and

a second securement member affixed to said second end of said tubular member, said cup member interposed between said second securement member and said anchor member.

2. The apparatus of claim 1, said wedge-receiving cavity of said anchor member being tapered so as to have a narrow end adjacent to said one side of said anchor member and a wide end adjacent to said opposite side of said anchor member, said portion of said tubular member being tapered so as to conform with the taper of said wedge-receiving cavity.

3. The apparatus of claim 1, said first securement member being of an annular configuration and threadedly secured to said first end of said tubular member.
