Abstract

A pocketformer includes a pocketformer body having a tapered exterior surface. The exterior surface has at least one portion along a length thereof of substantially constant diameter. The pocketformer body has a feature for engaging an anchor base in a concrete structure prior to pouring concrete and a grout ring having a substantially constant inner diameter substantially equal in diameter to the at least one portion. The grout ring has an exterior surface shaped to cause retention of the grout ring in set concrete.

Claims

1. A pocketformer, comprising:

a pocketformer body having an exterior surface, the exterior surface including at least one portion along a length thereof having a tapered profile and at least one portion along a length thereof having a substantially constant diameter, the pocketformer body having a feature for engaging an anchor base in a concrete structure prior to pouring concrete; and

a grout ring having a substantially constant inner diameter substantially equal in diameter to the at least one portion having a substantially constant diameter, the grout ring having an exterior surface shaped to cause retention of the grout ring in set concrete, the grout ring being removably affixable to the at least one portion having a substantially constant diameter.

2. The pocketformer of claim 1 wherein the grout ring is removably affixed to the at least one portion having a substantially constant diameter such that the exterior surface of the grout ring is in opposed taper direction to the exterior surface of the pocketformer body.

3. The pocketformer of claim 1 wherein the exterior surface of the grout ring is shaped to form a ledge in the concrete.

4. The pocketformer of claim 1 wherein the exterior surface of the pocketformer body comprises two tapered portions, each portion having a different taper angle disposed on opposed longitudinal ends of the at least one portion having a substantially constant diameter.

5. The pocketformer of claim 1 wherein the pocketformer body includes an outer member defining the exterior surface and a tube extending through the outer member, an end of the tube configured to be positioned in a wedge cavity of the anchor.

6. A pocketformer for forming a pocket adjacent a concrete anchor, the pocketformer comprising:

a body including a first end, a second end, and an outer surface extending between the first end and the second end, the first end configured to abut the anchor, the outer surface including a first portion having a tapered profile and a second portion having a substantially cylindrical profile, a diameter of the first portion proximate the first end being less than a diameter of the first portion proximate the second end; and

a ring removably coupled to the second portion, the ring having an exterior surface shaped to engage the concrete after it sets and retain the ring in the concrete.

7. The pocketformer of claim 6, wherein the exterior surface of the ring has a tapered profile.

8. The pocketformer of claim 7, wherein the ring is removably coupled to the second portion such that the tapered profile of the ring is oriented in an opposite direction to the tapered profile of the first portion.

9. The pocketformer of claim 6, wherein the exterior surface of the ring is shaped to form a ledge in the concrete facing toward the anchor.

10. The pocketformer of claim 6, wherein the outer surface of the body further includes a third portion having a tapered profile, wherein the second portion is positioned between the first portion and the third portion.

11. The pocketformer of claim 6, wherein the outer surface of the body further includes a third portion having a tapered profile, wherein the first portion defines a first taper angle and the third portion defines a second taper angle different from the first taper angle.

12. The pocketformer of claim 6, wherein the first end, the second end, and the outer surface are formed on an outer member, the body further including a tube extending through the outer member, an end of the tube configured to be positioned in a wedge cavity of the anchor.

13. The pocketformer of claim 12, wherein the tube includes a first end extending axially beyond the first end of the outer member and a second end extending axially beyond the second end of the outer member.
