Description
【考案の詳細な説明】
本考案はダクト、特にアルミニウム又はアルミ合金の所
要巾帯状体に長さ方向に向く多数の凹凸条を並行に形成
してこの帯状体を螺旋状に捲回すると共に隣接帯状体と
側縁同士結合一体化した長尺管よりなるダクト用として
好適な継手管に係るものである。[Detailed description of the invention] The present invention involves forming a large number of concave and convex strips oriented in the length direction in parallel on a duct, especially a band-like body of a required width made of aluminum or aluminum alloy, and winding this band-like body in a helical manner while adjoining the duct. The present invention relates to a joint tube suitable for use in a duct, which is made of a long tube whose side edges are integrally connected to a band-shaped body.
即ち本考案は、アルミニウム又はアルミ合金等の所要巾
帯状体１に長あ方向に向く多数の凹凸条２を並行に形成
してこの帯状体を螺旋状に捲回すると共に隣接帯状体と
側縁３同士接合一体化し短管体Ａを形成し且つこの短管

等しい寸法に形成し短管体の両端所要範囲をその外径が
該管体の内径と同径又は僅かに小となる寸法にプレス成
形し凹凸条を消失せしめたことを特徴とする。That is, in the present invention, a large number of uneven strips 2 facing in the longitudinal direction are formed in parallel on a strip 1 of a required width such as aluminum or aluminum alloy, and this strip is wound in a spiral shape, and the adjacent strips and side edges are wound in parallel. 3 are joined together to form a short tube body A, and the outer diameter of this short tube body is formed to be equal to the inner diameter of the duct which is provided with a spiral uneven strip, and the outer diameter of the short tube body covers the required range at both ends of the short tube body. It is characterized in that it is press-molded to a size that is the same diameter as or slightly smaller than the inner diameter of the tube, thereby eliminating the uneven stripes.
冑図中４はプレスした小径平坦部である。4 in the figure is the pressed small diameter flat part.
本考案は上記せる如き構造であり、その使用即ちタクト
Ｂを接続するに当っては一方のタクトの一端に継手管Ａ

より継手管の凹凸条２がダクトＢの凹凸条５に嵌合し無
理に螺入されて強固な結合となるもので、ダクトの接続
を著しく容易ならしめ得るという効果がある。The present invention has the structure as described above, and when using it, that is, connecting tact B, one end of one tact is connected to the joint pipe A.
One end of the small diameter portion 4 is screwed in, but since the outer diameter of the short tube body is formed to be equal to the inner diameter of the duct which is provided with a helical uneven strip, it cannot be rotated in the helical direction of the uneven strip. As a result, the uneven strips 2 of the joint pipe fit into the uneven strips 5 of the duct B and are forcefully screwed into the joint, resulting in a strong connection, which has the effect of making the connection of the ducts considerably easier.
