An anchor bolt locator is provided that is inexpensively manufactured on automatic die-press machines from sheet steel and a structural nut that does not require any welding, while also being easy to use and install with current, commonly-used building practices and anchor designs. The anchor bolt locator is made from a galvanized sheet metal chair and a structural nut attached to the chair by way of a friction fit.

1. An anchor bolt locator, comprising: a. a chair, having a plurality of legs, a bridge connecting the legs, said bridge having a top surface, with the plurality of legs extending from the bridge in the same direction away from said top surface of said bridge,b. a depression formed in the bridge of the chair, the depression having a side wall with an inner surface, the side wall extending away from the top surface of the bridge, the depression also having a bottom floor with a top surface,c. a structural nut received in the depression of the bridge, the structural nut having a top end, a bottom end, an internal, threaded bore forming an internal, threaded side wall, said structural nut also having an outer side wall defining an outer surface of said nut, wherein, the bottom end of the structural nut rests on the top surface of the bottom floor of the depression, and portions of the outer surface of the outer side wall of the structural nut are in contact with and in frictional engagement with portions of the inner surface of the side wall of the depression such that the structural nut is secured to the chair. 2. The anchor bolt locator of claim 1, wherein: the depression is formed with an opening in the bottom floor. 3. The anchor bolt locator of claim 1, wherein: the opening in the bottom floor of the depression is located in the center of the depression. 4. The anchor bolt locator of claim 1, wherein: the bottom floor of the depression is made from one or more tongues that extend inwardly from the side wall. 5. The anchor bolt locator of claim 4, wherein: one or more of said one or more tongues extends inwardly past the internal side wall of the internal bore of the structural nut. 6. The anchor bolt locator of claim 1, wherein: edge openings are formed in the side wall of the depression. 7. The anchor bolt locator of claim 1, wherein: a portion of said bridge surrounding said depression in said bridge of said chair is a substantially planar and relatively thin member. 8. The anchor bolt location of claim 7, wherein: said structural nut between said top end and said bottom end has a thickness that is substantially greater than said relatively thin portion of said bridge surrounding said depression. 9. The anchor bolt locator of claim 7, wherein: said depression in said bridge has a depth from said top surface of said bridge to said bottom floor of said depression with portions of said side wall of said depression extending from said top surface of said bridge to said bottom floor of said depression and said depth of said depression is substantially greater than said relatively thin portion of said bridge surrounding said depression. 10. The anchor bolt locator of claim 1, wherein: said outer side surface of the nut is made with flat faces to have a polygonal cross-section. 11. A method of making an anchor bolt locator, comprising: a. cutting a planar blank for a chair from a sheet of steel;b. bending said blank for said chair, so that a bridge is formed connecting downwardly depending legs on either side of said bridge, said legs extending away from a top surface of said bridge;c. forming a depression in said bridge, the depression having a side wall with an inner surface, the side wall extending away from the top surface of the bridge, the depression also having a bottom floor with a top surface;d. forming one or more embossments in the bridge in one or more portions of the bridge near the depression;e. placing a structural nut in the depression of the bridge, the structural nut having a top end, a bottom end, an internal bore forming an internal side wall, said structural nut also having an outer side wall defining an outer surface of said nut, such that the bottom end of the structural nut rests on the top surface of the bottom floor of the depression, and portions of the outer surface of the outer side wall of the structural nut is in alignment and in close proximity to portions of the inner surface of the side wall of the depression;f. following the placement of the structural nut in the depression in the bridge, pressing the embossments in the bridge in one or more portions of the bridge near the depression towards the original planar position of the bridge such that the metal that makes the embossments flows toward the depression and portions of the side wall of the depression are pressed against the outer side wall of the nut, creating a friction fit that secures the structural nut to the chair. 12. The method of claim 11, wherein: an opening is formed in the depression of the bridge before the structural nut is placed in the depression of the bridge. 13. The method of claim 12, wherein: mounting openings are formed in the bridge.
