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 upper and lower tubular elements connected by a shoulder. The upper element is disposed about the anchor rod threads and has an interior surface defined on a radius smaller than an anchor rod thread outer radius. The lower tubular element has an interior radius larger than an anchor nut outer dimension and is configured to define an air gap between the lower tubular element inner surface and an anchor nut encompassed thereby. A lower tubular element bottom edge is configured to form a physical barrier interface with the anchor rod base flange. At least one of the upper tubular element interior surface and the lower tubular element bottom edge are configured to form a sealing interface with anchor rod thread outer surfaces or an upper flange surface.
