  • Patent number: 5117607
    Abstract: A metal pole structure includes a plurality of elongated hollow pole sections interconnected end-to-end. Each section is formed with two or more elongated angled wall sections and a space extends longitudinally along each of the sections and the pole when assembled. Interconnecting diagonal braces extend across the longitudinal space. The braces interconnect with edge portions of wall sections on each side of the space to bridge the space to provide a structural wall section and to define access openings along the pole section to permit access to the interior of the hollow pole to effect the interconnection of the pole sections and the braces.
