DETAILED DESCRIPTION

[0012] Referring now to Figures 1 ¨3, a kit for orienting an anchor bolt 12 mounted in concrete 14 can include a cylindrical body 10 and a plurality of shims 16, 116. The cylindrical body 10 can be positionable over the anchor bolt 12 when the anchor bolt 12 is mounted in concrete 14. The cylindrical body 10 can extend a length 24 along a central longitudinal axis 18 between a top end 20 and a bottom end 22.

[0013] The cylindrical body 10 can define a radially-outer surface 26 extending a first circumference 28 about the central longitudinal axis 18. The radially-outer surface 26 can be smooth along the entire length 24. The radially-outer surface 26 can be spaced a first radius 30 from the central longitudinal axis 18. The radially-outer surface 26 can define an interface between the cylindrical body 10 and the concrete 14 when the cylindrical body 10 is positioned over the anchor bolt 12 and the concrete 14 has been poured.

[0014] The cylindrical body 10 can define a radially-inner surface 32 extending a second circumference 34 about the central longitudinal axis 18. The radially-inner surface 32 can be spaced a second radius 36 from the central longitudinal axis 18. The radially-inner surface 32 can be positioned radially inward of the radially-outer surface 26. The radially-inner surface 32 can be concentric with the radially-outer surface 26. The radially-inner surface 32 can define an interface between the cylindrical body 10 and the anchor bolt 12 when the cylindrical body 10 is positioned over the anchor bolt 12 and the concrete 14 has been poured.

[0015] Referring now to Figures 3 ¨5, a first shim 16 of the plurality of shims 16, 116 can define a top surface 38, a radially inwardly-facing surface 40, a radially outwardly-facing surface 42, a bottom surface 44, and circumferential side surfaces (such as the circumferential side surface referenced at 46). A second shim 116 of the plurality of shims

16, 116 can define a top surface 48, a radially inwardly-facing surface 50, a radially outwardly-facing surface 52, a bottom surface 54, and circumferential side surfaces (such as the circumferential side surface referenced at 56).
[0016] Each of the plurality of shims 16, 116 can have a thickness defined in a circumferential direction relative to the central longitudinal axis 18. The thickness of the first shim 16 is referenced at 58 and the thickness of the second shim 116 is referenced at 158. Each of the thicknesses can be less than one fourth of the first circumference 28.
Each of the plurality of shims 16, 116 can have a width defined in a radial direction relative to the central longitudinal axis 18. The width of the first shim 16 is referenced at 60 and the width of the second shim 116 is referenced at 160. The first shim 16 can define a variable width with a maximum width referenced at 60 and minimum width referenced at 60'; the second shim 116 can define a constant width. A height of the second shim 116 is referenced at 168. The first width 60 can be greater than a difference between the first radius 30 and the second radius 36. The second width 160 can be less than the difference between the first radius 30 and the second radius 36.

[0017] The cylindrical body 10 can be solid between the radially-inner surface 32 and the radially-outer surface 26 to ensure that the cylindrical body 10 will maintain its shape when the concrete 14 is poured around the anchor bolt 12. The cylindrical body 10 can formed from a material that renders the cylindrical body 10 destructible by hand with unpowered hand tools. For example, after the concrete 14 has set, the cylindrical body 10 can be dug out, broken down, destroyed, and/or picked apart by a tool such as a screwdriver. The cylindrical body 10 can thus be sacrificial.

[0018] The cylindrical body 10 can be formed from a foam material. The cylindrical body 10 can be formed from extruded or expanded polystyrene foam.
The cylindrical body 10 can be formed other materials that will retain form when positioned in the concrete 14 but will be easily removable from the concrete 14 without release coatings.
For example, one or more embodiments of the cylindrical body 10 can be formed from cork.

[0019] Referring again to Figure 1, the cylindrical body 10 can be defined by first and second halves 62, 162. Each of the first and second halves 62, 162 can define half of the radially-inner surface 32 and half of the radially-outer surface 26. A
quantity of adhesive can be disposed on at least one of the first and second halves 62, 162, such as the quantity of adhesive referenced at 64. The adhesive 64 can be operable to bond the first and second halves 62, 162 together around the anchor bolt 12.

[0020] In another approach to mounting the cylindrical body 10 (defined by first and second halves 62, 162) to the anchor bolt 12 can include taping one of the first and second halves 62, 162 to the anchor bolt 12, the first half 62 for example.
The tape can be pressed against the surfaces of the first half 62 so that the second half 162 can be positioned flush with the first half 62. Tape can then be used to tape the second half 162 to the first half 62.

[0021] A method of orienting the anchor bolt 12 using the kit will now be described. The method can begin by mounting the anchor bolt 12 to extend vertically upward. The anchor bolt 12 can include a base end 70 and shaft 72 extending the base end 70 to a distal end 74. Threads can be defined at the distal end 74. The cylindrical body 10 can then be positioned over an upper portion of the anchor bolt 12, a portion of the shaft 76 proximate to the distal end 74. The cylindrical body 10 can be positioned over the threads or below the threads. Liquid concrete 14 can then be poured around the anchor bolt 12 and the cylindrical body 10.

[0022] After the concrete 14 has set, the cylindrical body 10 can be removed by irreparably dismantling the cylindrical body 10. The cylindrical body 10 can be dug out with a tool such as screwdriver or a nail or any other tool. The entire cylindrical body 10 can be removed so that the surface of the concrete 14 is exposed. When the cylindrical body 10 is removed, a cavity is defined with a bottom and an inwardly-facing wall 78, as referenced in Figure 8.

[0023] After the cylindrical body 10 has been removed, the first shim 16 can be drive down into the cavity between the anchor bolt 12 and the inwardly-facing wall 78.
The first shim 16 can be used to urge the anchor bolt 12 in a particular direction so that the distal end 74 will be moved to a desired positioned. The position of the distal end 74 after the concrete 14 sets may not be desirable. The first shim 16 can be placed at a position along the circumference of the wall 78 that is opposite to the direction that the distal end 74 will be moved. The first shim 16 can be driven down to a first depth and the surface 40 can act against the shaft 72 to bend the anchor bolt 12 in a first direction, referenced at 80 in Figure 8. The deeper the first shim 16 is driven into the cavity, the more the shaft 72 will be bent.

[0024] After the first shim 16 has been positioned, the second shim 116 can be driven into the cavity between the anchor bolt 12 and the inwardly-facing wall 78 on a side of the cavity opposite to the first shim 16. The second shim 116 can be driven into the cavity a second depth and thereby bending the anchor bolt 12 in a second direction opposite to the first direction 80. The second depth will be less than the first depth.

[0025] The shims 16, 116 can be altered in size as necessary at the worksite.
Further, the process of positioning the shims 16, 116 and determining the respective depths can be iterative. After the distal end 74 is positioned as desired, the first shim 16 and the second shim 116 can be submerged by pouring grout 82 in the cavity.
