그러나, 상기한 바와 같은 나선 이중벽관은 그 제조과정이 사각 중공선재의 접합을 위하여 별도의 접합수지를 사용하거나, 고주파에 의하여 용융접합하여야 하므로 작업성이 낮고 생산원가가 고가로 형성되는 문제점이 있었다.However, the spiral double-walled pipe as described above has a problem in that its work process is low and the production cost is expensive because its manufacturing process requires the use of a separate bonding resin for the bonding of the rectangular hollow wire or by fusion bonding using high frequency. .
또한, 용융접합과정이 정밀하지 못할 경우에는 접합부위의 결합력이 균일않고, 누수등이 발생하는 문제점이 있었다.In addition, when the melt bonding process is not precise, there is a problem in that the bonding force of the joint portion is not uniform, leakage occurs.
이에, 본 고안은 상술한 문제점을 해결하기 위하여 안출한 것으로, 사각 중공선재를 나선 접합하여 나선 이중벽관을 제작함에 있어서, 나선 접합되는 사각 중공선재가 끼움 결속구조에 의하여 결속되게 구성한 것이다.Accordingly, the present invention has been devised to solve the above-described problems, and in the manufacture of spiral double wall pipe by spirally joining a rectangular hollow wire, the rectangular hollow wire to be spirally bonded is configured to be bound by a fitting binding structure.
