Abstract

A system of connecting a stiffener to the sidewall of a grain bin using a stud bolt having a first threaded end, a second threaded end and a feature positioned between the first end and a second end. A sealing member is positioned over the first end of the stud bolt, which in one case is a metallic washer with an affixed compressible sealing member. The first end of the stud bolt is inserted into a hole in the sidewall and an inner nut is placed over the first end inside the sidewall. As the inner nut is tightened, the feature is pulled toward the exterior surface of the grain bin thereby causing the sealing member to form a seal with the exterior surface of the grain bin. The second end of the stud bolt is inserted into a hole in the stiffener which is tightened onto the stud bolt.

First claim

What is claimed:

1. A grain bin system, comprising:
a sidewall;
the sidewall having an interior surface and an exterior surface;
the sidewall formed of a plurality of sheets;
a stiffener;
the stiffener having an interior surface and an exterior surface;
the stiffener extending a length;
the stiffener connected to the exterior surface of the sidewall by a stud bolt;
the stud bolt having a first threaded end, a second threaded end and a feature positioned between the first threaded end and the second threaded end;
wherein the first threaded end of the stud bolt extends through the sidewall;
wherein the second threaded end of the stud bolt extends through the stiffener;
wherein the feature of the stud bolt is positioned between the stiffener and the sidewall;
a sealing member positioned between the feature of the stud bolt and the exterior surface of the sidewall;
wherein the sealing member forms a seal with the exterior surface of the sidewall.

2. The system of claim 1 wherein the plurality of sheets are formed of a plurality of layers positioned in overlapping condition with one another.

3. The system of claim 1 wherein the sheets are corrugated.

4. The system of claim 1 wherein the feature of the stud bolt is a step, a shoulder, a flange, a hex head member, or a square head member.

5. The system of claim 1 wherein the sidewall is formed of a plurality of rings stacked on top of one another.

6. The system of claim 1 wherein the sealing member includes a washer.

7. The system of claim 1 wherein the sealing member includes a rigid washer and a compressible member.

8. The system of claim 1 further comprising
an inner nut connected to the first threaded end of the stud bolt and tightened against the interior surface of the sidewall such that the sidewall is tightened between the feature of the stud bolt and the inner nut.

9. The system of claim 1 further comprising
an outer nut connected to the second threaded end of the stud bolt and tightened against an exterior surface of the stiffener such that the stiffener is tightened to the sidewall.

10. The system of claim 1 wherein the stud bolt facilitates providing a seal between the feature and the exterior surface of the sidewall when a gap is present between the exterior surface of the sidewall and the interior surface of the stiffener.

11. The system of claim 1 further comprising
a rotation member positioned in an end of the stud bolt.

12. The system of claim 1 wherein the feature is a non-moveable part of the stud bolt.

13. The system of claim 1 wherein the feature is formed as part of the stud bolt.

14. The system of claim 1 wherein the feature is movable along a length of the stud bolt.

15. A grain bin system, comprising:
a cylindrical sidewall formed of a plurality of sheets aligned in a plurality of rings;
a stiffener connected to an exterior surface of the sidewall;
a stud bolt having a first threaded end, a second threaded end, and a feature positioned between the first threaded end and the second threaded end;
wherein the first threaded end of the stud bolt is inserted through the sidewall;
wherein the second threaded end of the stud bolt is inserted through the stiffener;
a sealing member positioned between the feature and the sidewall;
wherein when the stud bolt is tightened against the sidewall the sealing member forms a seal against the sidewall.

16. The system of claim 15 wherein the sheets are corrugated.

17. The system of claim 15 wherein the sheets are formed of a plurality of layers positioned in overlapping condition with one another.

18. The system of claim 15 wherein the feature of the stud bolt is a step, a shoulder; a flange; a hex head member, or a square head member.

19. The system of claim 15 wherein the sealing member is a compressible member.

20. The system of claim 15 wherein the sealing member includes a rigid washer and a compressible member.

21. The system of claim 15 further comprising
an inner nut connected to the first threaded end of the stud bolt and tightened against the interior surface of the sidewall such that the sidewall is tightened between the feature of the stud bolt and the inner nut.

22. The system of claim 15 further comprising
an outer nut connected to the second threaded end of the stud bolt and tightened against an exterior surface of the sidewall such that the sidewall is tightened between the feature of the stud bolt and the inner nut.

23. The system of claim 15 wherein the stud bolt facilitates providing a seal between the feature and the exterior surface of the sidewall when a gap is present between the exterior surface of the sidewall and the interior surface of the stiffener.

24. The system of claim 15 further comprising
a rotation member positioned in an end of the stud bolt.

25. A method of installing an external stiffener to a sidewall of a grain bin, the steps comprising;
providing a cylindrical sidewall formed of a plurality of sheets;
providing a stud bolt having a first threaded end, a second threaded end and a feature positioned between the first threaded end and the second threaded end;
inserting the first threaded end of the stud bolt through a Me in the sidewall;
placing a sealing member between the feature of the stud bolt and the sidewall;
tightening the first threaded end of the stud bolt thereby forming a seal between the sealing member and the sidewall;
inserting the second threaded end of the stud bolt through a hole in the stiffener;
tightening the second threaded end of the stud bolt against the stiffener thereby affixing the stiffener to the sidewall.

26. The method of claim 25 wherein the step of tightening the first threaded end of the stud bolt against the sidewall is facilitated by placing an inner nut on the first threaded end of the stud bolt and tightening the inner nut against an interior surface of the sidewall.

27. The method of claim 25 wherein the step of tightening the second threaded end of the stud bolt against the sidewall is facilitated by placing an outer nut on the second threaded end of the stud bolt and tightening the outer nut against an exterior surface of the stiffener.

28. A system for sealing a grain bin, comprising:
the grain bin having a sidewall;
the sidewall having an exterior surface and an interior surface;
the sidewall having a hole;
a stiffener;
the stiffener having a hole;
a stud bolt;
the stud bolt extending a length;
the stud bolt having a first threaded end and a second threaded end, wherein the first threaded end and second threaded end are opposite one another;
the stud bolt having a feature positioned along the length of the stud bolt between the first threaded end and the second threaded end;
wherein the first threaded end of the stud bolt extends through the hole in the sidewall of the grain bin;
wherein the second threaded end of the stud bolt extends through the hole in the stiffener;
wherein the feature of the stud bolt is positioned between the stiffener and the sidewall;
wherein the feature facilitates a seal between the stud bolt and the exterior surface of the sidewall.

29. The system of claim 28 , further comprising
a sealing member positioned between the feature and the sidewall, wherein the sealing member seals against the exterior surface of the sidewall.
