Abstract
The invention relates to an adjustable anchoring base for road sign posts, posts which are elements of a structural system, and the like. The object of the invention is to provide a pre-manufactured permanent anchoring base, intended primarily for installation approximately flush with finish grade, which allows rapid and simple initial mounting, temporary remounting of damaged posts, plumb alignment, and secure positioning of varied types of posts. The invention is comprised of a bottom component of heavy, cast material having embedded anchor bolts protruding above its top surface, the center of said component formed as a cavity of vertically slanted and tapered faces into which a post is inserted, centered, supported and restrained horizontally at the cavity's bottom surface. The top component restrains the post both horizontally and vertically, and is comprised of adjustable anchoring plates with slotted holes, flat ring washers, and threaded nuts, all secured to the bottom component's anchor bolts.
