ANTIGALLING ANCHOR BOLT AND METHOD
Disclosed is an anchor bolt including a wedge having a surface with a plurality of protrusions and a sleeve in operable communication with the surface. Furthermore, the sleeve is expandably receptive to the surface.
1 . An anchor bolt comprising:
a wedge having a surface with a plurality of protrusions; and
a sleeve in operable communication with the surface, the sleeve being expandably receptive to the surface.
2 . The anchor bolt of claim 1 , wherein the surface has a generally tapered shape.
3 . The anchor bolt of claim 2 , wherein the tapered shape is conical.
4 . The anchor bolt of claim 1 , wherein the surface has a constant angle of taper.
5 . The anchor bolt of claim 1 , wherein the surface has a varying angle of taper.
6 . The anchor bolt of claim 1 , wherein the sleeve perimetrically surrounds at least a portion of the wedge.
7 . The anchor bolt of claim 1 , wherein the plurality of protrusions have a corresponding plurality of recessions.
8 . The anchor bolt of claim 1 , wherein the plurality of protrusions are knurled.
9 . The anchor bolt of claim 1 , wherein the plurality of protrusions includes parallel ridges.
10 . The anchor bolt of claim 1 , wherein the plurality of protrusions includes a diamond pattern.
11 . The anchor bolt of claim 1 , wherein the plurality of protrusions includes a cross pattern.
12 . The anchor bolt of claim 1 , wherein the plurality of protrusions define a reduced contact area between the surface and the sleeve.
13 . The anchor bolt of claim 11 , wherein the reduced contact area defines an area of reduced galling bond strength.
14 . The anchor bolt of claim 1 , further comprising a threaded bolt portion.
15 . A method to reduce galling of an anchor bolt comprising, reducing contact area between a wedge surface and a sleeve of the anchor bolt.
16 . The method to reduce galling an anchor bolt of claim 15 , wherein the reducing contact area includes knurling the wedge surface.
17 . A method to reduce a breaking force between galled components of an anchor bolt comprising, reducing contact area between a wedge surface and a sleeve of the anchor bolt.
18 . The method to reduce a breaking force between galled components of an anchor bolt of claim 17 , wherein the reducing contact area includes knurling the wedge surface
