Abstract

An anchoring device for anchoring a threaded member in a substrate material. More particularly, an anchoring system for anchoring a threaded member in a substrate material, which anchoring system is designed to alleviate the stresses caused during use when water trapped within the anchoring system between an anchoring sheath and a threaded member expands upon freezing.

Claims

1. An anchoring device for anchoring a threaded member in a substrate material, comprising:

an anchoring sheath having a first end, a second end, a body portion disposed between the first end and the second end and at least two longitudinal ribs;

wherein the body portion has an internal bore and an internal cavity, wherein the internal bore is adapted to receive the threaded member; and

, wherein each longitudinal rib is disposed in a different plane intersecting a longitudinal axis of the anchoring sheath.

2. The anchoring device of claim 1, wherein at least one of the longitudinal ribs has a generally triangular cross-section.

3. The anchoring device of claim 1, having three longitudinal ribs spaced around the body portion 120°

apart.

4. The anchoring device of claim 1, further comprising a protective coating on at least a portion of an external surface of the anchoring sheath.

5. The anchoring device of claim 4, wherein the protective coating is a polymer powder coating.

6. An anchoring system for anchoring a threaded member in a substrate material, comprising:

(a) an anchoring sheath having a first end, a second end and a body portion disposed between the first end and the second end;

wherein the body portion has an internal bore and an internal cavity; and

,

(b) at least one compressible freeze protection element;

wherein the internal cavity is adapted to retain the at least one compressible freeze protection element and wherein the anchoring system is configured so that the threaded member does not compress the at least one compressible freeze protection element upon insertion of the threaded member into the anchoring sheath.

7. The anchoring system of claim 6, wherein the internal cavity is adapted to retain the at least one compressible freeze protection element and wherein the anchoring system is configured so that the threaded member does not compress the at least one compressible freeze protection element upon insertion of the threaded member into the anchoring sheath.

8. The anchoring system of claim 6, wherein the at least one compressible freeze protection element is at least partially compressed to facilitate its insertion into the internal cavity.

9. The anchoring system of claim 8, wherein the at least one compressible freeze protection element comprises a single compressible element.

10. The anchoring system of claim 9, wherein the single compressible element has a shape selected from the group consisting of a sphere, a cylinder and a polyhedron.

11. The anchoring system of claim 10, wherein the single compressible element has a shape selected from the group consisting of a sphere, a cylinder, a cube and a hexahedron.

12. The anchoring system of claim 8, wherein the at least one compressible freeze protection element comprises a plurality of individual compressible elements.

13. The anchoring system of claim 12, wherein the plurality of individual compressible elements have different shapes and sizes.

14. The anchoring system of claim 8, wherein the at least one compressible freeze protection element is made of a material selected from the group consisting of foam, rubber and gel.

15. The anchoring system of claim 8, wherein the at least one compressible freeze protection element is constructed of a material selected from the group consisting of microcellular polyurethane foam and polystyrene foam.

16. The anchoring system of claim 8, wherein the at least one compressible freeze protection element is constructed of microcellular polyurethane foam.

17. An anchoring device for anchoring a threaded member in a substrate material, comprising:

(a) an anchoring sheath having a first end, a second end and a body portion disposed between the first end and the second end;

wherein the body portion has an internal bore and an internal cavity;

wherein the internal bore opens into the internal cavity and wherein the internal bore is adapted to receive the threaded member;

(b) three longitudinal ribs of generally triangular cross-section, extending outwardly from the body portion along at least a segment of said body portion and spaced around the body portion 120°

apart; and

,

(c) a compressible freeze protection element disposed within the internal cavity;

wherein the body portion has a top region extending part way from the first end towards the second end, which top region is devoid of longitudinal ribs.

18. The anchoring device of claim 17, wherein the compressible freeze protection element is at least partially compressed to facilitate its insertion into the internal cavity.

19. A method for anchoring a threaded member in a substrate material, comprising:

(a) incorporating an anchoring sleeve into the substrate material;

(b) inserting at least one compressible freeze protection element into the anchoring sleeve; and

,

(c) threading the threaded member into the anchoring sleeve.

20. The method of claim 19, wherein the threaded member does not compress the at least one compressible freeze protection element.

21. An anchoring device for anchoring a threaded member in a substrate material, comprising:

an anchoring sheath having a first end, a second end, a body portion disposed between the first end and the second end; and

at least one longitudinal rib extending outwardly from the body portion along at least a segment of the body portion;

wherein the body portion has an internal bore adapted to receive the threaded member and an internal cavity;

wherein a cross-sectional area of the internal cavity exceeds a cross-sectional area of the internal bore at a plane where the internal cavity and the internal bore intersect.

22. The anchoring device of claim 21, wherein the at least one longitudinal rib has a generally triangular cross-section.

23. The anchoring device of claim 21, having at least two longitudinal ribs, wherein each longitudinal rib is disposed in a different plane intersecting the longitudinal axis of the anchoring sheath.

24. The anchoring device of claim 21, having three longitudinal ribs spaced around the body portion 120°

apart.

25. An anchoring device for anchoring a threaded member in a substrate material, comprising:

an anchoring sheath having a first end, a second end, a body portion disposed between the first end and the second end and a protective coating on at least a portion of an external surface of the anchoring sheath;

wherein the body portion has an internal bore adapted to receive the threaded member and an internal cavity;

wherein a cross-sectional area of the internal cavity exceeds a cross-sectional area of the internal bore at a plane where the internal cavity and the internal bore intersect.

26. The anchoring device of claim 25, wherein the protective coating is a polymer powder coating.
