Abstract
A hollow fiberglass utility pole includes a pair of segments that are a fiberglass sheet that has a semicircular cross-section. The segments have first and second longitudinal edges with male and female couplers respective shapes that have a complimentary relationship to each other for mechanical engagement thereof. The fiberglass pole is assembled by engaging the first longitudinal edge of one segment with the second longitudinal edge of the other segment at an installation site. The fiberglass pole may be used as a sheath to encase an existing wooden pole.
Claims3
A hollow structure adapted to be assembled to form a pole at the desired location of erection, comprising:
- a plurality of pultruded, resin and fiberglass composite segments each having an uninterrupted desired longitudinal length corresponding to the desired length of said pole, each segment including longitudinally extending edges conformed for mating with corresponding opposed edges of the other ones of said segments for defining said hollow pole;
- said opposed edges including longitudinally extending male and female couplers to mechanically couple said edges together to secure the segments together to define said pole;
- said male coupler includes a plurality of longitudinally extending teeth and said female coupler includes said channel including a plurality of longitudinally extending locking surfaces to receive by resilient expansion said male coupler and be engaged by said teeth;
- said male coupler being shaped as an insert including said teeth on both sides thereof;
- and
- at least one longitudinally extending rail projecting radially from at least one segment for mounting fixtures thereon.
An assembly conformed for interlocking attachment to form a hollow cylindrical structure, comprising:
- a plurality glass reinforced resin composite segments each formed to define one position of an arc of a cylindrical surface and each including a first and second longitudinal edge, said first longitudinal edge having a longitudinal cavity provided with a plurality of opposed first teeth in the interior thereof and said second longitudinal edge being provided with a longitudinal projection having a plurality outwardly directed second teeth on the exterior thereof, said longitudinal projection in one said segment being conformed to resilient receipt in said longitudinal cavity of another one of said segment and,
- a radial projection aligned generally radially on the exterior of said tubular structure along each said first longitudinal edge of each said segment, whereby an interlocked engagement between said first and second teeth provides an engagement of said segments to each other to form a tubular structure.
