Abstract

An anchor for attaching a structure to a concrete structure, comprises an anchor rod having a lower threaded portion for being embedded in a concrete structure and an upper portion for extending outside the concrete structure; an anchor body including a first threaded central opening for threadedly receiving one end portion of the lower threaded portion; and a support including a floor. The support includes a second central threaded opening through the floor portion for threadedly receiving another end portion of the lower portion.

First claim

I claim:

1. An anchor for supporting a load, comprising:
a) an anchor rod having a lower threaded portion for being embedded in a concrete structure and an upper portion for extending outside the concrete structure;
b) an anchor body, which is unitary, including a first threaded central opening for threadedly receiving one end portion of said lower threaded portion;
c) a support including a floor portion;
d) said support including a second central threaded opening in said floor portion for threadedly receiving another end portion of said lower threaded portion; and
e) said anchor body is disposed a distance above said floor portion.

2. An anchor as in claim 1 , wherein said support is molded.

3. An anchor as in claim 2 , wherein said second central threaded opening is molded in said support.

4. An anchor as in claim 1 , wherein said anchor body is a nut.

5. An anchor as in claim 1 , wherein said anchor body includes an outer cylindrical surface.

6. An anchor as in claim 5 , wherein said anchor body includes an outwardly disposed shoulder disposed at a bottom portion of said cylindrical surface.

7. An anchor as in claim 6 , wherein said shoulder is integral with said anchor body.

8. An anchor as in claim 5 , wherein said cylindrical surface is threaded.

9. An anchor as in claim 6 , wherein:
a) said anchor body includes a circumferential groove at a bottom portion of said cylindrical surface;
b) said shoulder is a split ring removably disposed in said groove; and
c) said ring includes a portion extending outside said groove to form said shoulder.

10. An anchor as in claim 1 , wherein:
a) said anchor body includes an outer cylindrical surface;
b) a plurality of circumferential grooves are disposed on said cylindrical surface;
c) a plurality of split rings are disposed in respective said grooves; and
d) portions of said rings extend outwardly of said cylindrical surface.

11. A holder for an anchor rod, comprising:
a) a support including a floor portion;
b) said support including a plurality of leg portions attached to said floor portion and extending downwardly therefrom;
c) said support including a central threaded opening through said floor portion for threadedly receiving an end portion of an anchor rod;
d) said support including a vertical peripheral wall portion attached to said floor portion and said leg portions, said wall portion extending above said floor portion; and
e) said leg portions extending above said floor portion and attached to said wall portion.

12. A holder as in claim 11 , wherein said leg portions are spaced apart from each other to provide multiple inlets and outlets between adjacent leg portions to facilitate flow of concrete slurry underneath said floor portion.

13. A holder as in claim 11 , wherein said floor portion includes a plurality of openings to facilitate flow of concrete slurry to underneath said floor portion.

14. A holder as in claim 11 , wherein said support is molded.

15. A holder for an anchor rod, comprising:
a) a support including a floor portion, and an outer peripheral edge;
b) said support including a central threaded opening in said floor portion for threadedly receiving an end portion of an anchor rod;
c) said floor portion having a bottom surface for resting on a surface prior to said support being embedded in concrete; and
d) said support including a vertical wall portion extending from said outer peripheral edge and spaced from an anchor body.

16. A holder as in claim 15 , wherein said wall portion includes a top peripheral flange.

17. A holder as in claim 15 , wherein said bottom surface is substantially flat.

18. A holder as in claim 15 , wherein said floor portion includes a raised portion disposed around said central threaded opening.

19. An anchor as in claim 15 , wherein said support is molded.

20. A holder for an anchor rod, comprising:
a) a support including a floor portion;
b) said support including a central threaded opening in said floor portion for threadedly receiving an end portion of an anchor rod;
c) said floor portion having a bottom surface for resting on a surface prior to said support being embedded in concrete; and
d) said support including a plurality of radially inwardly and vertically disposed rib portions having vertical through-openings.

21. An anchor as in claim 20 , wherein said support is molded.
