[ EN ]

WE CLAIM:

1. A combination, comprising:

a slug or package of chemical anchoring adhesive, the slug or package having a proximal end and a distal end;

a rod having a proximal end, a distal end, and a threaded or corrugated outer surface, the proximal end of the rod connected to the distal end of the slug or package of chemical anchoring adhesive; and

a jacket surrounding and containing the slug or package of chemical anchoring adhesive and the rod, the jacket having an open distal end for receiving an anchor pin and an open proximal end for dispensing chemical anchoring adhesive.

2. The combination of Claim 1, wherein the rod comprises a penetrator having a proximal end, an open internally threaded distal end, and a threaded or corrugated outer surface, the pointed proximal end of the penetrator connected to the distal end of the slug or package of chemical anchoring adhesive.

3. The combination of Claim 1 , wherein the j acket has a relatively narrower barrel portion, and a relatively wider anchor lip portion.

4. The combination of Claim 1, further comprising an anchor pin having a proximal end and a distal end, the proximal end of the anchor pin connected to the distal end of the rod.

5. The combination of Claim 1, wherein the chemical anchoring adhesive comprises about 10-90% by weight of a methacrylic copolymer and about 10-90% by weight of a reinforcement filler.

6. The combination of Claim 1, wherein the chemical anchoring adhesive comprises about 30-65% by weight of an epoxy resin and about 30-65% by weight of a reinforcement filler.

7. The combination of Claim 5, wherein the chemical anchoring adhesive comprises two compositions which are ultimately mixed together.

8. The combination of Claim 6, wherein the chemical anchoring adhesive comprises two compositions which are ultimately mixed together.

9. A combination, comprising:

a slug or package of chemical anchoring adhesive, the slug or package having a proximal end and a distal end; and

a penetrator having a pointed proximal end, an open distal end, and a threaded or corrugated outer surface, the pointed proximal end of the penetrator connected to the distal end of the slug or package of chemical anchoring adhesive so that the pointed proximal end is at least partially surrounded by chemical anchoring adhesive.

10. The combination of Claim 9, further comprising a jacket surrounding and containing the slug or package of chemical anchoring adhesive and the penetrator, the j acket having a relatively narrower barrel portion, a relatively wider anchor lip portion, an open distal end for receiving an anchor pin and an open proximal end for dispensing chemical anchoring adhesive.

11. The combination of Claim 9, comprising a threaded anchor pin having a proximal end and a distal end, the proximal end of the anchor pin connected to the open distal end of the penetrator.

12. An integrated method of applying a chemical anchoring adhesive and an anchor pin to a borehole, comprising the steps of:

providing combination including a slug or package of chemical anchoring adhesive, the slug or package having a proximal end and a distal end, and a rod having a proximal end, a distal end and a threaded or corrugated outer surface, the proximal end of the rod connected to the distal end of the slug or package of chemical anchoring adhesive;

providing an anchor pin having a proximal end and a distal end;

engaging the proximal end of the anchor pin to the distal end of the rod; positioning the combination adjacent to a borehole; and driving the combination and a portion of the anchor pin into the borehole.

13. The integrated method of Claim 12, wherein the combination further comprises a j acket surrounding and containing the slug or package of chemical anchoring adhesive, the jacket having an open distal end for receiving the anchor pin and an open proximal end for dispensing chemical anchoring adhesive, and the positioning step further comprises the step of positioning the combination so that the proximal end of the jacket is adjacent to an opening to the borehole.

14. The integrated method of Claim 12, wherein the jacket further comprises a relatively narrower barrel portion and a relatively wider anchor lip portion, and the positioning step further comprises the step of positioning the combination so that the anchor lip portion surrounds the opening in the borehole.

15. The integrated method of Claim 12, wherein the rod comprises a pentrator having a pointed proximal end, and open distal end and a threaded or corrugated outer surface, the pointed proximal end of the penetrator connected to the distal end of the slug or package of chemical anchoring adhesive.

16. The integrated method of Claim 12 , wherein the open distal end of the penetrator is internally threaded, the anchor pin is threaded, and the step of connecting the proximal end of the anchor pin to the distal end of the penetrator further comprises the step of screwing the proximal end of the anchor pin into the distal end of the penetrator.

17. The integrated method of Claim 12, wherein the driving step further comprises the step of pounding the distal end of the anchor pin using a driving tool.

18. The method of Claim 17, wherein the pounding step is performed using a hammer.

19. The method of Claim 17, wherein the pounding step causes the release and mixing of the chemical anchoring adhesive in the borehole.

20. The method of Claim 19, wherein the pounding step further causes the step of scrubbing and scoring an inner wall of the borehole using the outer surface of the penetrator.
