Abstract

A stackable rebar support chair having a support chair and a support plate detachable to each other. The support chair includes a base having multiple upstanding posts and downwardly extending legs designed to suspend the base above surface. The base can include multiple holes to permit the free flow of concrete around the support chair. Multiple centering supports can connect to and extend between each of the upstanding posts and an upper surface of the base to provide support to the posts and to permit gravity to assist positioning the supported rebar to a generally central position on the base. The base can include ribs extending from its lower surface to provide support to the base from the weight of the rebar. The support plate can include multiple generally upright pegs having recesses to receive the legs.

Claims

1. A stackable rebar chair for supporting rebar above a surface, the stackable rebar chair comprising:

a support chair having a base with a plurality of posts extending upwardly and a plurality of legs extending downwardly; and

a plurality of support brackets extending between each of the posts and the base, wherein at least two support brackets facilitate the positioning of the rebar in a center portion of the base between the plurality of posts and plurality of legs.

2. The stackable rebar chair of claim 1, further including at least one socket extending into an end of each of the plurality of posts for receiving legs of a second stackable rebar chair.

3. The stackable rebar chair of claim 2, wherein each of the sockets is axially aligned with a long axis of the plurality of posts

4. The stackable rebar chair of claim 1, wherein each of the plurality of legs has a pointed end.

5. The stackable rebar chair of claim 4, further comprising a support plate having a panel and a plurality of pegs extending upwardly therefrom, each of the plurality of pegs having bore for receiving the pointed ends of the plurality of legs.

6. The stackable rebar chair of claim 1, further comprising a support plate attached to the plurality of pegs.

7. The stackable rebar chair of claim 1, further comprising at least one rib disposed on a lower surface of the base.

8. The stackable rebar chair of claim 1, further comprising a first rib and a second rib extending from a lower surface of the base, wherein the first rib extends between a pair of the plurality of legs and the second rib extends between a second pair of the plurality of legs.

9. The stackable rebar chair of claim 8, wherein the first and second ribs cross each other.

10. The stackable rebar chair of claim 8, further comprising a central post extending from the lower surface of the base, wherein the first and second ribs intersect with the central post.

11. The stackable rebar chair of claim 8, further comprising at least one hole extending through a portion of the base.

12. A stackable rebar chair for supporting rebar above a surface, the stackable rebar chair comprising:

a support chair having a base with a plurality of posts extending upwardly and a plurality of legs extending downwardly; and

a centering bracket system disposed to each of the posts and the base to facilitate the positioning of the rebar in a center portion of the base between the plurality of posts and plurality of legs, each centering bracket system including;

a first centering bracket extending in a first direction along a peripheral edge of the base;

a second centering bracket extending in a second direction along a peripheral edge of the base, wherein the first and second centering brackets are orthogonal to each other;

13. The stackable rebar chair of claim 12, further comprising a third centering bracket extending toward a center of the base.

14. The stackable rebar chair of claim 12, further including at least one socket extending into an end of each of the plurality of posts for receiving legs of a second stackable rebar chair.

15. The stackable rebar chair of claim 14, wherein each of the sockets is axially aligned with a long axis of the plurality of posts.

16. The stackable rebar chair of claim 12, wherein each of the plurality of legs has a pointed end.

17. The stackable rebar chair of claim 16, further comprising a support plate having a panel and a plurality of pegs extending upwardly therefrom, each of the plurality of pegs having bore for receiving the pointed ends of the plurality of legs.

18. The stackable rebar chair of claim 12, further comprising a support plate attached to the plurality of pegs.

19. The stackable rebar chair of claim 12, further comprising at least one rib disposed on a lower surface of the base.

20. The stackable rebar chair of claim 12, further comprising a first rib and a second rib extending from a lower surface of the base, wherein the first rib extends between a pair of the plurality of legs and the second rib extends between a second pair of the plurality of legs.

21. The stackable rebar chair of claim 20, wherein the first and second ribs cross each other.

22. The stackable rebar chair of claim 20, further comprising a central post extending from the lower surface of the base, wherein the first and second ribs intersect with the central post.
