An anchor positioning assembly 10 embodying the present invention is illustrated in FIGS. 1-3 and 5-8. The positioning assembly 10 can assist with the positioning of an anchor 20 within a casting frame or housing 25 (shown in FIGS. 2 and 3) by coupling to one or more reinforcing members 30 prior to the casting of concrete. As shown in FIGS. 2, 3 and 5-8, the reinforcing members 30 can be arranged in a grid pattern 35, for example, as discussed below. In some embodiments, a portion of the positioning assembly 10 can also further strengthen the anchor 20 in the concrete form 40 (shown in FIGS. 1-3) when the form 40 is lifted. The positioning assembly 10 includes an anchor 20, one or more positioning members 45, and a void former 50.

FIG. 4 illustrates an exemplary anchor 20 for use in the positioning system 10. The anchor 20 can be formed from metal, such as steel, for example. The anchor 20 includes a first or upper portion 60 and a second or lower portion 65. The upper portion 60, at least in part, can be surrounded by the void former 50 when assembled, as discussed below, and at least in part, can define an aperture 70. The lower portion 65 is connected to one or more positioning members 45. The one or more positioning members 45 and the lower portion 65, at least in part, is immersed in the concrete form 30 (shown in FIGS. 2-3), as discussed below.

As illustrated in FIG. 4, the anchor 20 includes a single bar 75 forming the upper portion 60 and the lower portion 65. The bar 75 includes a first leg 80, a second leg 85, and an intermediate section 90. The intermediate section 90 includes at least one apex section 95. The first leg 80 includes a first end 100 of the bar 75, and the second leg 85 includes a second end 105 of the bar 75. In some embodiments, the first end 80 can further include a first foot 110, and the second end 80 can include a second foot 115. The first foot 110 and the second foot 115 can be secured to the first end 80 and the second end 85, respectfully, or can each be an integral portion of the bar 75.

In other embodiments, the anchor 20 can varying in shape, size and form. For example, the positioning system 10 can use a W-foot anchor, such as the anchor shown and described in U.S. patent application Ser. No. 10/648,935, the entire content of which is hereby incorporated by reference.

The positioning assembly 10 further includes one or more positioning members 45 to couple to one or more reinforcing members 30, such as the reinforcing bars 30 shown in the illustrated embodiments. In other embodiments, the reinforcing members 30 can vary in width, length, shape, size and material. The reinforcing members 30 can include a beam, for example.

As shown in FIGS. 2, 3 and 5-8, the exemplary positioning assembly 10 includes a first positioning member 200 and a second positioning member 205. Each positioning member 200 and 205 includes a first end portion 210, a second end portion 215, and an intermediate section 220. The first end portion 210 of each positioning member 200 and 205 couples to a first reinforcing bar 240 positioned within the casting frame 25, and the second end portion 215 of each positioning member 200 and 205 couples to a second reinforcing bar 245 positioned within the casting frame 25.

In the illustrated embodiments, the first end portion 210 and the second end portion 215 are configured to engage with the first reinforcing bar 240 and the second reinforcing bar 245, respectively, such that each positioning member 200 and 205 can be subjected to tension when coupled to the reinforcing bars 240 and 245. The positioning member 200 and 205 may also be either substantially or at least partially supported by reinforcing bars 240 and 245. Furthermore, the positioning member can be subjected to compression when couples to the reinforcing bars 240 and 245, or can be at least partially supported by the reinforcing bars 240 and 245 and also be subjected to compression when coupled to the bars 240 and 245.

In some embodiments, the first end portion 210 of each positioning member 200 and 205 can further be configured to partially surround a portion of the first reinforcing bar 240. For example, in the illustrated embodiments, the first end portion 210 can further include a curved section 250 having an inner surface 252 and an outer surface 255 (with respect to the reinforcing bar 240). The curved section 250 can at least partially surround (e.g., partially hook around) a portion of the first reinforcing bar 210. The inner surface 252 can couple, indirectly or directly, to the reinforcing bar 240.

In some embodiments, the second end portion 215 of each positioning member 200 and 205 can further be configured to create a snap fit between the second send portion 215 and the second reinforcing bar 245. For example, in the illustrated embodiments, the second end portion 215 of each positioning member 200 and 205 can further include a first curved section 260 and a second curved section 265. As shown in FIGS. 3, 5 and 6, the first curved section 260 includes an outer concave surface 270 and an inner concave surface 272. The first curved section 260, the outer surface 270 and inner surface 272 present concave profiles with respect to a first direction, such as the direction from the first and second reinforcing bars 240 and 245. The second curved section 265 includes an outer convex surface 275 and an inner convex surface 278. The second curved section 265, the outer surface 275 and the inner surface 278 present convex profiles substantially with respect to the same first direction (e.g., the direction from the first and second reinforcing bars 240 and 245).

In the illustrated embodiments, the second end portion 215 also includes an inflection section 280 (shown in FIG. 6). The inflection section 280 provides the transition between the first curved section 260 (and the outer and inner concave surfaces 270 and 272) and the second curved section 265 (and the outer and inner convex surfaces 275 and 278). The inflection section 280 also includes an outer inflection surface 282 and an inner inflection surface 285 (shown in FIG. 6). In some embodiments, such as the illustrated embodiments, the first curved section 260, the second curved section 265 and the inflection section 280 are arranged to substantially form an S-shaped end portion 215.

In some embodiments, the inner concave surface 272, the inner inflection surface 280 and the inner convex surface 278 can all, in part, couple to the second reinforcing bar 245. In other embodiments, the second reinforcing bar 245 can couple to one of the inner surfaces 272, 278 or 280 or a combination of the inner surfaces 272, 278 and 280. In some embodiments this coupling can be accomplished by welding.

As shown in the illustrated embodiments, both the first reinforcing bar 240 and the second reinforcing bar 245 are included in the grid pattern 35, and each are positioned substantially parallel to the other. In other embodiments (not shown), the first end portion 210 of the first positioning member 200 can couple to one reinforcing member 30 while the first end portion 210 of the second positioning member 205 can couple to another reinforcing member 30. Similarly, in other embodiments (not shown), the second end portion 215 of the first positioning member 200 can couple to one reinforcing member 30 while the second end portion 215 of the second positioning member 205 can couple to another reinforcing member 30. In further embodiments, the reinforcing members 30 can be arranged in a different pattern, such as, for example, a pattern with two or more non-parallel, non-perpendicular reinforcing members 30.

In some embodiments, the intermediate section 220 of each positioning member 200 and 205 can be coupled to the anchor 20, when the positioning assembly 10 is assembled. As shown in the illustrated embodiments, the intermediate section 220 of the first positioning member 200 can be secured to the first leg 80 of the anchor 20, and the intermediate section 220 of the second positioning member 205 can be secured to the second leg 85 of the anchor 20. In some embodiments, such as the illustrated embodiments, the positioning members 45 (e.g., positioning members 200 and 205) are secured to the lower portion 65 of the anchor 20 and is embedded in the concrete form 40. The positioning members 200 and 205 can be secured to the respective legs 80 and 85 of the anchor 20 by welding, a securing device (e.g., bolt, sleeve, joint and the like), or the like. In the illustrated embodiments, each positioning member 200 and 205 is secured to the respective leg 80 and 85 of the anchor by a welded joint 290.

The exemplary positioning assembly 10 further includes at least one void former 50. The void former 50 can be formed of a variety of materials such as, for example, rubber, plastic, wood, a combination of two or more listed materials or any other material that is easily removable from the concrete (e.g., after hardening). The void former 50 can include a first portion 305 and a second portion 310. The first portion 305 and the second portion 310 of the void former 50 can be held together to create a sufficiently tight seal between the void former 50 and, at least in part, the upper portion 60 of the anchor 20. The first portion 305 and the second portion 310 can be distinct parts (not shown), can be an integral part (as shown in FIGS. 3 and 5-8), or can be at least partially connected together (not shown). The void former 50 can comprise as few as one part and as many as desired to create a desired void in the concrete form 40. Similarly, one or more void formers 50 can be used to create one or more voids in the concrete around the anchor 20.

In the illustrated embodiment, the first portion 305 and the second portion 310 is a single part having an upper surface 315, and the first portion 305 connects to the second portion 310 by a live hinge 320 included in the upper surface. The void former 50 further includes a recess 325 defined by the upper surface 315. In the illustrated embodiment, a second hinge 330 is positioned within the recess 325. The second hinge 330 includes one or more apertures 340 to receive one or more fasteners (not shown), such as a nail, bolt, screw or the like, to fasten the second hinge 330 to the void former 50.

The one or more fasteners (not shown) can also aid in the removal of the void former 50 from the positioning assembly 20 and the concrete form 40 (e.g., when the concrete is hardened). For example, a first bolt (not shown) can be received by a first aperture 350 positioned at least partially on the first portion 305 of the void former 50, and a second bolt (not shown) can be received by a second aperture 355 positioned at least partially on the second portion 310 of the void former 50. To remove the void former 50 from the positioning assembly 20, a device or user can force the bolts (not shown) together via the live hinge 320 and the second hinge 330 such that the first portion 305 and the second portion 310 are forced apart. When the void former 50 is removed from the positioning assembly 20 and the concrete form 40, the concrete form defines a void 400 as shown in FIG. 1.

The one or more fasteners (not shown) can also be used to fasten the void former 50 to a cover 402 substantially covering the concrete casting frame 25, such as a piece of plywood 402 (shown in FIGS. 2 and 3). In some embodiments, the cover 402 (e.g., the plywood) can level concrete when the concrete is cast.

In some embodiments the positioning assembly 10 allows for the void former 50, and consequently the anchor 20, to be held in place by the positioning members 200 and 205 coupled to the reinforcing members 30. The positioning members 200 and 205 can hold in place the void former 50 which surrounds the anchor 20.

In an exemplary implementation, the anchor positioning system 10 (shown in FIGS. 2, 3, 5-8) is positioned within the concrete casting frame 25 when the reinforcing members 30 (e.g., reinforcing bars 240 and 245) are positioned within the frame 25. The first end portions 210 of the positioning members 200 and 205 are placed partially around the first reinforcing bar 240, such that the inner surfaces 252 included in the first end portions 210 couple with the first reinforcing bar 240. The second end portions 215 of the positioning members 200 and 205 are lowered onto the second reinforcing bar 245 and positioned such as to engage the second reinforcing bar 245 in a snap fit. When the anchor positioning system 10 is positioned within the frame 25, the concrete is poured into the frame 25 covering at least a portion of the reinforcing members 30 (e.g., reinforcing bars 240 and 245) and at least a portion of the anchor positioning assembly 10.

When the concrete hardens (forming a concrete form 40), the void former 50 is removed from the concrete form 40 exposing a portion of the anchor 20. As shown in FIG. 1, when the void former 50 is removed and the concrete has formed, at least a part of the upper portion 60 of the anchor is not immerse in the concrete form 40. A lifting apparatus 405 (shown partially in FIG. 1) such as, for example, a crane, can engage with the exposed portion of the anchor 20 to lift the concrete member 40.

The embodiments described above and illustrated in the figures are presented by way of example only and are not intended as a limitation upon the concepts and principles of the present invention. As such, it will be appreciated by one having ordinary skill in the art that various changes in the elements and their configuration and arrangement are possible without departing from the spirit and scope of the present invention as set forth in the appended claims.
