Abstract

Apparatuses, systems, and methods for centralizing rebar in a shaft are provided. The systems include a rebar centralizer system comprising a first ring and a second ring configured to be positioned in an angular relationship with each other. The first and second rings are configured to at least partially intersect so as to present at least one interior corner in which a section of rebar can be secured.

Claims

1. A rebar centralizer system comprising:

a first ring; and

a second ring configured to be positioned in an angular relationship with said first ring,

wherein said first and second rings are configured to at least partially intersect so as to present at least one interior corner for receiving a section of rebar.

2. The system of claim 1, wherein the first and second rings are coupled together in said angular relationship.

3. The system of claim 2, wherein said angular relationship is perpendicular.

4. The system of claim 3, wherein said second ring is aligned generally in a parallel relationship with a centerline of said first ring, and wherein said second ring is offset from the centerline of said first ring.

5. The system of claim 1 further comprising at least one securement component for securing the first and second rings to the section of rebar, wherein at least a portion of the section of rebar is retained within the interior corner of said centralizer system.

6. The system of claim 5, wherein the securement component comprises a wire-tie.

7. The system of claim 1, wherein the first and second rings are comprised essentially of metal.

8. The system of claim 7, wherein the first and second rings are coupled together via weld.

9. The system of claim 1, wherein the first and second rings are comprised of plastic.

10. The system of claim 9, wherein the first and second rings are injection molded.

11. The system of claim 9, wherein the first and second rings are coupled together via one or more snap-fit connections.

12. A method for centrally positioning a section of rebar in a shaft, the method comprising:

(a) providing a first ring and a second ring at least partially intersecting so as to present at least one interior corner;

(b) positioning the section of rebar adjacent to the first and second rings and within the interior corner;

(c) securing the section of rebar to the first and second rings;

(d) placing the section of rebar within the shaft.

13. The method according to claim 12, wherein during said placing of step (d), portions of each of the first and second rings contact sidewalls of the shaft, such that the section of rebar is longitudinally aligned within the shaft.

14. The method according to claim 12, wherein the first and second rings are coupled together in a generally perpendicular relationship.

15. The method according to claim 12, wherein said securing of step (c) comprises securing the section of rebar to the first and second rings via a wire-tie.

16. The method according to claim 12, further comprising the step of securing a third ring and a fourth ring to the section of rebar, wherein the third and fourth rings are spaced apart from the first and second rings.

17. A rebar centralizer component, the component comprising:

a first generally ring-shaped element including a first half and a second half,

wherein an inner diameter of said first ring-shaped element as measured across the first half is greater than the inner diameter of said first ring-shaped element as measured across the second half,

wherein an interior surface of the first half includes at least one notch for receiving a portion of a second ring-shaped element.

18. The rebar centralizer component of claim 17, wherein the interior surface of the first half of said first ring-shaped element comprises two aligned notches, wherein the notches are configured to receive the portion of the second ring-shaped element, such that the second ring-shaped element is retained within an interior of said first ring-shaped element.

19. The rebar centralizer component of claim 17, wherein an exterior surface of the second half of said first ring-shaped element comprises two aligned tabs, wherein the tabs are configured to secure a portion of a third ring-shaped element to the exterior surface of said first ring-shaped element.

20. The rebar centralizer component of claim 17, wherein first ring-shaped element is formed from plastic.
