Abstract

An anchor rod support comprises a support having a floor and legs extending downwardly from the floor with openings between the legs; and the support including threads for attaching thereto an anchor rod.

First claim

I claim:

1. An anchor embedded in concrete for supporting a load, comprising:
a) an open tubular body to allow concrete to enter inside the tubular body;
b) a threaded body disposed inside the tubular body;
c) a rod having one end attached to the threaded body and another end for attachment to a load;
d) the tubular body including a sidewall, a top opening and a bottom opening;
e) the sidewall including an inside surface and an outside surface; and
f) the outside surface including a first shoulder extending therefrom.

2. The anchor as in claim 1 , wherein the tubular body is circular in cross-section.

3. The anchor as in claim 1 , wherein the tubular body is substantially cylindrical.

4. The anchor as in claim 1 , wherein the inside surface includes a second shoulder extending therefrom.

5. The anchor as in claim 4 , wherein the inside surface includes an upwardly and outwardly disposed surface and an inwardly projecting surface.

6. The anchor as in claim 5 , wherein the upwardly and outwardly disposed surface terminates into the inwardly projecting surface to define the second shoulder.

7. The anchor as in claim 4 , wherein the second shoulder is disposed at an upper portion of the tubular body.

8. The anchor as in claim 4 , wherein the second shoulder is disposed at an intermediate portion of the tubular body.

9. The anchor as in claim 4 , wherein:
a) the inside surface includes a circumferential groove; and
b) the second shoulder includes a split ring partly disposed in the groove such that a portion of the ring extends outside the groove beyond the inside surface.

10. The anchor as in claim 9 , wherein the groove is disposed at an upper portion of the cylindrical sleeve.

11. The anchor as in claim 4 , wherein the threaded body is disposed below the second shoulder.

12. The anchor as in claim 1 , wherein the outside surface includes a conical surface.

13. The anchor as in claim 1 , wherein the outside surface includes a downwardly and inwardly disposed surface and an outwardly projecting surface.

14. The anchor as in claim 13 , wherein the inwardly and downwardly disposed surface terminates into the outwardly projecting surface to define the first shoulder.

15. The anchor as in claim 1 , wherein the first shoulder is disposed at a lower portion of the tubular body.

16. The anchor as in claim 1 , wherein the first shoulder is disposed at an intermediate portion of the tubular body.

17. The anchor as in claim 1 , wherein:
a) the tubular body is a cylindrical sleeve;
b) the outside surface includes a circumferential groove; and
c) the first shoulder includes a split ring partly disposed in the circumferential groove such that a portion of the ring extends outside the groove beyond the outside surface.

18. The anchor as in claim 17 , wherein the groove is disposed at a lower portion of the cylindrical sleeve.

19. The anchor as in claim 17 , wherein the groove is disposed at an upper portion of the cylindrical sleeve.

20. The anchor as in claim 17 , wherein the groove is disposed at an intermediate portion of the cylindrical sleeve.

21. The anchor as in claim 1 , wherein the threaded body is disposed in a lower portion of the tubular body.

22. The anchor as in claim 1 , wherein the threaded body includes a nut.

23. The anchor as in claim 1 , and further comprising:
a) a support including a base portion with a central opening;
b) the one end of the rod is attached to the central opening; and
c) the tubular body and the threaded body are supported by the base portion.

24. The anchor as in claim 23 , wherein the support includes leg portions extending from the base portion.
