초록 ▼

A tubular tapered composite pole for supporting utility lines and a method for making the same. The pole is formed from a plurality of elongated panels made of pultruded composite material having a height H1 in the range of 30 feet-120 feet. An interlocking structural groove is formed on one of the side edges of the panel during the pultrusion process. The other side edge of the panel is formed by a biased angle cut from the bottom edge of the panel to its top edge to give it a generally trapezoidal shape. A tongue shaped interlocking structure is machined along the length of the angularly cut side edge. The panels have a length L1 along their bottom edge in the range of 6"-24" and a length L2 along their top edges in the range of 3"-16". The respective tongue and groove structure along the side edges of the panels is interlocked together to form a closed loop extending from their top edges to their bottom edges to form the tubular tapered pole. The special double structural groove, known as a fir tree joint is designed to allow insertion elastically, and then provide significant clamping pressure once interlocked.

[ What is claimed is:] [1.]1. A tubular tapered composite pole for supporting utility lines comprising:a plurality of vertically oriented elongated primary panels each having an inner surface, an outer surface, a bottom edge, a top edge, a left side edge, a right side edge, a height (H1) in the range of 30-120 feet, a length (L1) along said bottom edge in the range of 6"-24", a length (L2) along said top edge in the range of 3"-16", a thickness (T1) in the range of 0.100-0.800 inches, and (L1) is greater than (L2) to give said panels a generally trapezoidal shape; said primary panels being formed of pultruded composite materials by a pultrusion process;interlocking tongue and groove structure formed on said primary panels along their respective left and right side edges substantially along their entire height (H1); said groove structure having been formed on said primary panels during said pultrusion process and said groove structure has an outer jaw and an inner jaw each having inner surfaces configured to form a fir tree-shaped groove having at least first and second locking cavities; said tongue structure having been formed on said primary panels after said panels have been formed by said protrusion process; said tongue structure having a fir tree-shaped cross section having an outer surface, an inner surface and an outer end; a head portion is formed on said outer end, spaced inwardly from said head portion is formed a first outer surface machined groove and a first inner surface machined groove; spaced inwardly from the respective first outer surface machined groove and said first inner surface machined groove are a second outer surface machined groove and a second inner surface machined groove; a double sided tooth portion is formed between said respective first and second machined grooves; said head portion of a first one of said primary panels snap locks into said second locking cavity of a second one of said primary panels and said double sided tooth portion of said first one of said primary panels snap locks into said first cavity of said second one of said primary panels to form a double snap lock mechanical joint; and said thickness of said tongue structure is no greater than (T1) at any point; andsaid vertically oriented primary panels arranged to form a closed loop at their top edges and their bottom edges such that said tongue structure on each panel is interlockingly engaged in said groove structure of said adjacent panel; said primary panels having been assembled together by snapping laterally said adjacent tongue and groove structure together; said primary panels having planar outer surfaces and planar inner surfaces in their pultruded formed state; when said primary panels are assembled together said outer surfaces and said inner surfaces of said primary panels remain in a planar state and are not subjected to stresses that would occur if they were bent in order to assemble adjacent panels together.
