Abstract:
1. A junction fitting assembly comprising: at least a first and a second lengths of material having a first constant cross sectional area including a first external surface having a mold pattern; a first annular flange having a first internal surface complementary to the mold pattern and having a second constant cross sectional shape along at least a portion of its axial length, said first annular flange having at least a first external surface on an opposite side of the first annular flange with respect to the first internal surface, and following a first shape of a portion of said first internal surface of said first annular flange, said first annular flange having a first annular opening for admitting and continuously fitting around said first constant cross sectional area of said first length of material; a second annular flange having a second internal surface complementary to the mold pattern and having a third constant cross sectional shape along at least a portion of its axial length, said second annular flange having at least a second external surface on an opposite side of the first annular flange with respect to the first internal surface, and following a second shape of a portion of said first internal surface of said second annular flange, said second annular flange having a second annular opening for admitting and continuously fitting around said first constant cross sectional area of said second length of material; said second annular flange joined to said first annular flange, said first external surface of said first annular flange and said second external surface of said second annular flange joining at a corner to form said junction fitting, the junction fitting attachable to each of said first and said second lengths of material by insertion of each of said first and said second lengths of material into their associated annular opening of said junction fitting whereby the junction fitting enables the first and said second lengths of material to structurally reinforce each other, said junction fitting having an external shape portion which differs from the mold pattern of at the first and second lengths of material by only the thickness of the first external surface of the first annular flange.
