Extension piece for a utility pole

摘要

A pole is mounted in a tubular filament wound support mounted in the ground and supporting the pole standing upwardly therefrom so as to provide an extension for the pole to increase its height or to replace a rotten lower end or to provide an environmentally friendly mounting which avoids toxic preservatives reaching the ground. The tubular body has a hollow interior with one end substantially closed by a dome shaped insert formed during the filament winding process and an opposed open end for receiving a bottom end portion of the pole as a loose fit. A first engagement arrangement on the tubular body is arranged adjacent the open mouth and includes three clamping screws mounted in a reinforcing ring formed by an annular rib of wound filament. A second engagement arrangement on the tubular body spaced downwardly from the first engagement but above the bottom end is formed by an annular rib on the inside surface defining a frusto-conical upper surface extending inwardly to a sharp apex which co-operates with a generally pointed lower end defined by three surfaces cut from the pole and converging toward a lowermost point, each surface being separated from the next by a respective one of a plurality of lines, each line engaging the circular innermost apex so as to hold the pole substantially wedged against movement.
