UNION DE CAÑA DE BAMBU DESMONTABLE

Unión de caña de bambú provista de - una primera caña de bambú (1) que incide sobre una segunda caña de bambú (2) que se encuentra en ángulo, - estando fijada en la zona final por lo menos de la primera caña de bambú (1) una pieza insertada longitudinal (3), y - existiendo un elemento de unión longitudinal, que une la primera parte de la pieza insertada longitudinal (3) de la primera caña de bambú (1) con la otra caña de bambú (2) por lo menos indirectamente, caracterizado porque la pieza insertada longitudinal (3) en la primera caña de bambú (1) se posiciona en dirección longitudinal, de tal manera que la primera y segunda caña de bambú (1, 2) unidas entre sí comprimen la segunda caña de bambú (2) con su superficie exterior contra la superficie frontal dirigida a ella de la pieza insertada (3). A lengthways insertion piece fixed to one end of the first bamboo tube (1) is releasably indirectly joined to the second bamboo tube (2) by a screw (4) and/or arranged centrally and lengthways in the first tube carrying the insert. The insert is glued and/or forcibly joined to the inside of the tube using a cross dowel (5). A crossways insert (15) is fixed to the second tube by screws (7) and/or by adhesive at a point aligned with the first tube insert. The connector is positively joined to the insert in tube by a cross dowel so the connector reaches into the second tube and is forcibly joined to the inside of the tube by a second dowel. The head (4a) of screw bears on the far endface of the insert and the screw nut (6) bears on the cross insert (19) endface furthest from the tube. The screw runs free through the insert bore (9) and is externally threaded (12) at its free end, the nut being screwed to the insert by locknuts (8). The insert is built up of connected bamboo rods.
