Abstract

A pocketformer for use with an anchor body in post-tensioning concrete has a body having a first side and a second side and a first end and a second end and an interior, a front face formed adjacent the first end, and a tubular member formed in the interior of the body. The first side tapers from the second end to the first end. The second side tapers from the second end to the first end. The first side has an angle of taper greater than an angle of taper of the second side. The body has a generally hollow interior. The tubular member extends from the first end to the second end within the interior of the body. The angle of taper of the first side is approximately 45°.

Claims

1. A pocketformer for use with an anchor body in post-tensioning concrete comprising:

a body having a first side and a second opposite side and a first end and a second end, said first side tapering from said second end to said first end, said second side tapering from said second end to said first end, said first side having an angle of taper greater than an angle of taper of said second side, said angle of taper being approximately 45°

, said body having a generally hollow interior;

a front face formed adjacent said first end; and

a tubular member formed in said interior of said body, said tubular member extending from said first end to said second end within said interior of said body.

2. The pocketformer of claim 1, said front face having a connecting area formed thereon suitable for connecting said body to the anchor body.

3. The pocketformer of claim 2, said connecting area having a lip extending outwardly from said front face, said lip being circular so as to suitably fit over an end of the anchor body, said tubular member being concentric with said lip of said connecting area.

4. The pocketformer of claim 1, said interior of said body having support structures formed therein.

5. The pocketformer of claim 4, said support structures comprising:

a first strut radiating outwardly from a side of said tubular member to said first side of said body;

a second strut radiating outwardly from an opposite side of said tubular member to said second side of said body;

a cross strut extending between a third side and a fourth side of said body; and

a transverse strut radiating outwardly from said tubular member to said third side and to said fourth side.

6. The pocketformer of claim 1, said tubular member having an inner diameter suitable for receiving a sheathed tendon therein.

7. The pocketformer of claim 1, said body tapering constantly from said first side to said second side.

8. The pocketformer of claim 1, said first side and said second side being curved.

9. A pocketformer assembly for use in post-tensioning of concrete comprising:

an anchor body having a cavity therein;

a tendon extending through said cavity of said anchor body; and

a pocketformer connected to said anchor body, said tendon passing through an interior of said pocketformer, said pocketformer comprising;

a body having a first side and a second side and a first end and a second end, said first side tapering from said second end to said first end, said second side tapering from said second end to said first end, said first side having an angle of taper greater than an angle of taper of said second side, said angle of taper of said first side being approximately 45°

, said body having a generally hollow interior;

a front face formed adjacent said first end, said front face connected to said anchor body, said front face having a lip extending outwardly from said front face, said lip being circular so as to fit over an end of the anchor body; and

a tubular member formed in said interior of said body, said tubular member extending from said first end to said second end within said interior of said body, said interior of said body having support structures formed therein, said support structures comprising;

a first strut radiating outwardly from a side of said tubular member to said first side of said body;

a second strut radiating outwardly from an opposite side of said tubular member to said second side of said body;

a cross strut extending between a third side and a fourth side of said body; and

a transverse strut radiating outwardly from said tubular member to said third side and to said fourth side.

10. The pocketformer of claim 9, said tendon having a sheathed portion, said sheathed portion received in an interior of said tubular member.

11. The pocketformer of claim 9, said body tapering continuously from said first side to said second side.

12. The pocketformer of claim 9, said first side and said second side being curved.

13. The pocketformer of claim 9, said front face having a protrusion formed thereon, said protrusion comprising:

a wall extending outwardly from said front face, said wall having a portion adjacent said connecting area, said portion having an angle of taper similar to said angle of taper of said first side; and

a cap affixed on said wall.
