I claim the ornamental design for a fence post anchoring structure, as shown and described.
FIG. 1 of the drawings is a perspective view showing the front, right side, and top of a fence post anchoring structure embodying the design of my invention;
FIG. 2 is a right side elevation view of the fence post anchoring structure;
FIG. 3 is a front elevation view;
FIG. 4 is a left side elevation view;
FIG. 5 is a back elevation view;
FIG. 6 is a top plan view; and,
FIG. 7 is a bottom plan view.
The fence post anchoring structure is the combination of a hollow square tube affixed atop a spike component for anchoring a vinyl fence post in a vertically extending hole drilled into a concrete pad, footing, or other concrete structure.
The characteristic feature of the design resides in an upstanding hollow square tube affixed atop a flat square plate to which is welded a pointed square-cross-section rod in a position such that the rod extends through a central opening in the plate, perpendicular to top and bottom surfaces of the plate.
