A pole, such as for a parking meter, that is reinforced by a hardening compound applied to its surface, preferably in vertical strips, to prevent theft, and a method of anchoring the pole or other upright object. The hardening compound is preferably a solder that is applied to the external surface of the pole by welding. Once it cools, this hardening compound cannot be cut with an ordinary hacksaw. For esthetic purposes, and to prevent rust to the pole, a PVC pipe with a slightly greater diameter than the pole is placed over and around the pole. In a preferred embodiment, the pole is welded to a base plate, with hollow metal cylinders welded to and extending from an opposite surface of the plate. Holes are drilled (or otherwise formed) in a concrete (or other solid) surface, epoxy is inserted into the holes, the metal cylinders are inserted into the holes, and when the epoxy hardens the cylinders and base plate are bonded to the concrete. The base plate and cylinders can also be used to anchor other upright objects to a concrete surface. In the preferred embodiment, circular transverse holes are made in the top of the pole using a plasma cutter, and expander jaws are then welded to the interior of the pole, to securely attach the head of the parking meter to the pole. |
