Similarly, one or morevoid formers 50 can be used to create one or more voids in the concrete around theanchor 20. - In the illustrated embodiment, the
first portion 305 and thesecond portion 310 is a single part having anupper surface 315, and thefirst portion 305 connects to thesecond portion 310 by alive hinge 320 included in the upper surface. The void former 50 further includes arecess 325 defined by theupper surface 315. In the illustrated embodiment, asecond hinge 330 is positioned within therecess 325. Thesecond hinge 330 includes one ormore apertures 340 to receive one or more fasteners (not shown), such as a nail, bolt, screw or the like, to fasten thesecond 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 afirst aperture 350 positioned at least partially on thefirst portion 305 of the void former 50, and a second bolt (not shown) can be received by asecond aperture 355 positioned at least partially on thesecond portion 310 of the void former 50. To remove the void former 50 from thepositioning assembly 20, a device or user can force the bolts (not shown) together via thelive hinge 320 and thesecond hinge 330 such that thefirst portion 305 and thesecond portion 310 are forced apart. When the void former 50 is removed from thepositioning assembly 20 and theconcrete form 40, the concrete form defines a void 400 as shown inFIG. 1 . - The one or more fasteners (not shown) can also be used to fasten the void former 50 to a
cover 402 substantially covering theconcrete casting frame 25, such as a piece of plywood 402 (shown inFIGS. 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 theanchor 20, to be held in place by thepositioning members members 30. Thepositioning members anchor 20. - In an exemplary implementation, the anchor positioning system 10 (shown in
FIGS. 2, 3 , 5-8) is positioned within theconcrete casting frame 25 when the reinforcing members 30 (e.g., reinforcingbars 240 and 245) are positioned within theframe 25. Thefirst end portions 210 of thepositioning members bar 240, such that theinner surfaces 252 included in thefirst end portions 210 couple with the first reinforcingbar 240. Thesecond end portions 215 of thepositioning members bar 245 and positioned such as to engage the second reinforcingbar 245 in a snap fit. When theanchor positioning system 10 is positioned within theframe 25, the concrete is poured into theframe 25 covering at least a portion of the reinforcing members 30 (e.g., reinforcingbars 240 and 245) and at least a portion of theanchor 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 theanchor 20. As shown inFIG. 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 theconcrete form 40. A lifting apparatus 405 (shown partially inFIG. 1 ) such as, for example, a crane, can engage with the exposed portion of theanchor 20 to lift theconcrete 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.
