Abstract

A cover includes a body adapted to secure over a fitting disposed in a prestressed concrete member for lifting the concrete member. The body has a surface feature configured to achieve a substantially fluid tight seal with the concrete member.

Claims

1. A cover comprising:

a body comprising;

a surface feature configured to achieve a substantially fluid tight seal with the a concrete member having a void with a fitting disposed therein; and

a protrusion extending from the body and configured to engage the void;

wherein the body is adapted to secure over the fitting disposed in a the void and engage the void for lifting the concrete member.

2. The cover of claim 1, wherein the surface feature includes a layer of adhesive material.

3. The cover of claim 1, wherein the surface feature is a substantially planar region.

4. The cover of claim 1, wherein the surface feature includes a rib.

5. The cover of claim 1, wherein the surface feature extends substantially continuously along the body.

6. The cover of claim 1, wherein the surface feature extends outwardly from the body.

7. The cover of claim 1, wherein the surface feature forms a recess in the body.

8. The cover of claim 1, wherein the body includes a raised portion opposite the surface feature.

9. The cover of claim 1, wherein the protrusion comprises a discontinuity configured to bend and reduce insertion force required to engage the void.

10. The cover of claim 9, wherein the protrusion includes a taper.

11. The cover of claim 10, wherein the body includes a recessed region substantially surrounding the protrusion, the recessed region disposed between the protruding portion and the surface feature.

12. The cover of claim 1, wherein the body contains a pigment similar to a pigment of the concrete member.

13. The cover of claim 1, wherein the body is composed of a resilient material.

14. The cover of claim 1, wherein the body is composed of a nonmetal.

15. The cover of claim 14, wherein a portion of the body adjacent the surface feature is resilient.

16. A cover comprising:

a body adapted to secure over a fitting disposed in a void of in a prestressed concrete member for lifting the prestressed concrete member, the body comprising;

a surface feature configured to achieve a substantially fluid tight seal with the prestressed concrete member;

a protrusion portion extending from the body and configured to engage the void; and

a raised portion opposite the surface feature.

17. The cover of claim 16, wherein the surface feature includes a layer of adhesive material.

19. The cover of claim 16, wherein the body includes a recessed region substantially surrounding protruding portion, the recessed region disposed between the protruding portion and the surface feature.

18. (canceled)

20. A cover comprising a body adapted to secure over a fitting disposed in a void of a concrete member for temporarily securing an object to the concrete member,

the body comprising:

a surface feature configured to achieve a substantially fluid tight seal with the concrete member

a protrusion extending from the body and configured to engage the void.
