Abstract

An anchor stud includes a stud portion including a body portion having a first end that extends to a second end though an intermediate portion. A wedge member is operatively coupled to the second end of the stud portion. The wedge member includes a body having a generally frustoconical profile and is formed from a material having a Vickers hardness greater than about 220 HV. A sleeve element is positioned on the stud portion at the second end adjacent the wedge member. The sleeve element is formed from a material having a Vickers hardness greater than about 220 HV.

Claims (24)

1. An anchor stud comprising:

a stud portion including a body portion having a first end that extends to a second end though an intermediate portion;

a wedge member operatively coupled to the second end of the stud portion, the wedge member formed from a material having a Vickers hardness greater than about 220 HV; and

a sleeve element positioned on the stud portion at the second end adjacent the wedge member, the sleeve element being formed from a material having a Vickers hardness greater than about 220 HV.

2. The anchor stud according to claim 1 , wherein the wedge member is formed from a material having a Vickers hardness of between about 240 HV and about 280 HV.

3. The anchor stud according to claim 1 , wherein the sleeve element is formed from a material having a Vickers hardness of between about 240 HV and about 280 HV.

4. The anchor stud according to claim 1 , wherein the sleeve element includes at least one gripping member having a hardness that is distinct from the hardness of remaining portions of the sleeve element.

5. The anchor stud according to claim 1 , wherein the sleeve element includes at least one gripping element having a hardness of at least 240 HV.

6. The anchor stud according to claim 1 , wherein the Vickers hardness is measured to a depth of between about 0.005 inches (0.127 mm) and about 0.025 inches (0.635 mm).

7. The anchor stud according to claim 1 , wherein the wedge member is formed from a hypoeutectic steel.

8. The anchor stud according to claim 7 , wherein the wedge member is formed from a medium carbon steel.

9. The anchor stud according to claim 7 , wherein the medium carbon steel is between about a 1030 steel and about a 1060 steel.

10. The anchor stud according to claim 1 , wherein the sleeve element is formed from a hypoeutectic steel.

11. The anchor stud according to claim 9 , wherein the sleeve element is formed from a medium carbon steel.

12. The anchor stud according to claim 11 , wherein the medium carbon steel is between about a 1030 steel and a 1060 steel.

13. The anchor stud according to claim 1 , wherein the sleeve element is formed from martensite steel.

14. The anchor stud according to claim 13 , wherein the sleeve element is formed from pre-hardened martensite steel.

15. The anchor stud according to claim 1 , wherein at least one of the wedge member and sleeve element is treated with one of a heat treating, annealing, and spherodized annealing process.

16. An anchor stud comprising:

a stud portion including a body portion having a first end that extends to a second end though an intermediate portion;

a wedge member operatively coupled to the second end of the stud portion, the wedge member including a body having a generally frustoconical profile, the wedge member being formed from a material having a first hardness;

a sleeve element positioned on the stud portion at the second end adjacent the wedge member, the sleeve element being formed from a material having a second hardness; and

at least one gripping element formed on the sleeve element, the at least one gripping element having a hardness that is distinct from the second hardness.

17. The anchor stud according to claim 16 , wherein the at least one gripping element has a hardness that is greater than the second hardness.
