Modular composite pole

摘要

A modular composite utility pole has a plurality of sections, each with a tapered hollow tube having a plurality of plies, wherein a first end has a larger diameter than a second end, wherein each section is adapted to join at least one adjoining section at a joint wherein the first end of an upper section overlaps the second end of a lower section, the lower section having a ledge proximate to the second end of the lower section, with a fastener passing through the joint via apertures in the sections, and wherein, when the modular composite utility pole is erected, the joint is self-located by the joint features, and wherein substantially all vertical load is transferred between sections via the a surface of the second end of the upper section resting upon the ledge of the lower section. Also disclosed are individual sections and methods of making them.

主权项

1. A section of a modular composite pole, comprising:
a tapered hollow tube comprising a plurality of plies having one or more filaments wound at an angle relative to a longitudinal axis of the tapered hollow tube, and an outer periphery; a first end, and a second end,
wherein the first end has a larger diameter than the second end, and an inner periphery sized so as to define a gap between said inner periphery and an outer periphery of an adjacent section received therein; at least one aperture proximate to an end and adapted to receive a fastener; and a built-up ledge around and extending beyond the outer periphery of the tapered hollow tube and proximate to the second end thereof constructed and arranged to receive substantially all vertical load from an adjacent section resting thereon; wherein a joint is formed upon assembly with the adjacent section, the joint does not rely upon friction between the inner periphery of the section and the outer periphery of the adjacent section.
