METHOD AND STRUCTURE FOR AN ANCHOR ROD CAP
First Claim
Patent Images
1. An anchor rod cap, comprising:
- an upper tube having an inner surface defined on an upper tube inner surface radius from a cap central axis, where in use the upper tube inner surface is adapted to tightly engage and form a frictional interface friction-fit with an outer thread surface of an anchor rod bolt defined on an outer thread radius from a rod bolt central axis, the bolt outer thread surface radius corresponding to and greater than the upper tube inner surface radius, the upper tube inner surface adapted to remain spaced from an inner thread surface of the anchor rod bolt within the outer thread radius and more proximate to the bolt central axis than the outer thread surface;
the upper tube ending in a transitional shoulder disposed outward relative to the cap central axis;
the transitional shoulder transitioning into a bottom enclosure having an inner surface adapted to be spaced from and encompass but not engage an anchor nut threaded onto the anchor rod bolt;
a bottom edge located at a bottom of the bottom enclosure; and
where in use the bottom enclosure inner surface and the bottom edge are disposed circumferentially encompassing but not engaging the anchor nut, and the friction-fit of the upper tube inner surface about the threaded anchor rod bolt outer thread surface is adapted to hold the anchor rod cap in place relative to the threaded anchor rod bolt.

Abstract
An anchor rod cap and method for protecting an anchor rod bolt/nut/lower flange assembly are provided. An anchor rod is provided having an upper tubular element adapted to be disposed about anchor rod threads and having an interior surface defined on a radius smaller than an anchor rod thread outer radius. A lower bottom enclosure is adapted to be spaced from an anchor nut located on the bolt.

7. An assembly, comprising:
-
a threaded anchor rod bolt having an outer thread surface located on an outer thread radius relative to a central bolt axis and an inner thread surface within the outer thread radius and more proximate to the bolt central axis than the outer thread surface; a threaded anchor nut tightened about the threaded anchor rod bolt into a forceful engagement with an anchor flange assembly; and an anchor rod cap upper tube having an inner surface defined on an upper tube inner surface radius from a cap central axis, the rod bolt outer thread radius corresponding to and greater than the upper tube inner surface radius, the upper tube inner surface tightly engaging and forming a frictional interface friction-fit with the threaded anchor rod bolt outer thread surface and spaced from the threaded anchor rod bolt inner thread surface; the anchor rod cap upper tube ending in a transitional shoulder disposed outward from the rod cap central axis; and the anchor rod cap transitional shoulder transitioning into an anchor rod cap bottom enclosure having an inner surface and a bottom edge both adapted to be spaced from outer surfaces of the anchor nut and to encompass but not engage the anchor nut; wherein the bottom enclosure inner surface and bottom edge encompass but do not engage the anchor nut, and the frictional interface friction-fit of the upper tube inner surface about the threaded anchor rod bolt outer thread surface holds the anchor rod cap in place relative to the threaded anchor rod bolt. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method for protecting an anchor rod assembly, comprising:
-
disposing an anchor rod cap about an anchor rod assembly, the anchor rod assembly comprising a threaded anchor rod bolt having an outer thread surface located on an outer thread radius relative to a central axis of the threaded anchor rod bolt and an inner thread surface within the outer thread diameter and more proximate to the bolt central axis than the outer thread surface, and an anchor nut threaded about the anchor rod bolt into an engagement with an anchor flange assembly at a bottom end of the threaded anchor rod bolt; the anchor rod cap comprising an upper tube having an inner surface defined on an upper tube inner surface radius from a cap central axis less than the bolt outer thread radius, the upper tube ending in a transitional shoulder disposed outward relative to the cap central axis, the transitional shoulder transitioning into a bottom enclosure having a bottom edge and an inner surface defined on a bottom enclosure radius from the cap central axis greater than the upper tube inner surface radius; the upper tube inner surface tightly engaging and forming a frictional interface friction-fit with the anchor rod bolt outer thread surface and remaining spaced from the bolt inner thread surface, thereby holding the anchor rod cap in place relative to the threaded anchor rod bolt; and the bottom enclosure inner surface encompassing and spaced from and not engaging the anchor nut threaded onto the anchor rod bolt. - View Dependent Claims (14, 15, 16, 17, 18)
