Abstract

본 발명은 평강관과 파형강관을 일체로 형성한 관체 및 그 제조방법에 관한 것으로, 구체적으로는 관체를 제조하는 과정에서 두개의 강판을 인출시켜 하나는 평강판 그대로의 형상을 유지하면서 양측단만 각각 절곡방향을 달리하여 절곡시키고, 다른 하나의 강판을 표면에 길이방향의 굴곡부와 양측단에 절곡방향을 달리한 모양을 절곡시켜 이를 평강판과 서로 합지시킨후, 나선방향으로 말아 관체를 형성시키되, 이때 평강판과 표면에 굴곡부를 형성한 파형강판은 관체로 말아지기 직전에 양측단부가 서로 합지된 상태에서 관체로 말아지므로 완전하게 일체화되는 것이며, 평강판 또는 파형강판을 막론하고 이를 일체화시켜 말았을때 자체탄성력(즉, 본래의 판체로 되돌아가려는 복원력)이 작용함으로 파형강관 내부의 평강관이 서로 타이트하게 조립고정된 상태를 유지토록 한 것이다.The present invention relates to a tube formed integrally with a flat steel pipe and a corrugated steel pipe and a method for manufacturing the same, specifically, by drawing two steel plates in the process of manufacturing the pipe, one of the two ends while maintaining the shape of the flat steel plate Each bent in different bending directions, the other steel sheet is bent in the longitudinal direction on the surface and the shape of the bending direction on both sides ends and laminated with each other, then rolled in a spiral direction to form a tubular body. At this time, the flat steel plate and the corrugated steel plate having the bent portion formed on the surface are completely integrated because they are rolled into the tubular body in the state where both ends are laminated together just before being rolled into the tubular body. When it is pressed, self-elastic force (that is, restoring force to return to the original plate) is applied, so that the flat steel pipes inside the corrugated steel pipes are tightly tightened together. One will ever maintain a fixed state.
