Description

나선관용 연결장치{Apparatus for connecting for spiral pipe}[0001] APPARATUS FOR CONNECTING SPIRAL PIPE [0002]

본 발명은 나선관용 연결장치에 관한 것으로, 보다 상세하게는 외주면에 나선돌기가 형성된 복수의 나선관을 상호 연결시키며 특히 나선관의 절단부 피치와 동일한 피치를 갖는 슬리브패킹을 각 나선관의 절단면에 밀착 결합함으로써 기밀성 및 수밀성을 향상시킬 수 있는 나선관용 연결장치에 관한 것이다.The present invention relates to a connecting device for a spiral tube, and more particularly, to a connecting device for a spiral pipe, in which a plurality of spiral pipes having spiral protrusions formed on the outer circumferential surface thereof are connected to each other and a sleeve packing having a pitch equal to that of the spiral pipe, Thereby improving airtightness and watertightness.

일반적으로 각종 관체의 연결 접속구조는 그 관체의 형상과 재질 및 용도에 따라 이에 상응하는 연결 소켓, 플랜지, 반원형 접합구 등을 사용하여 접속 연결한다.Generally, the connecting connection structures of various tubular bodies are connected and connected by using connection sockets, flanges, semicircular joints or the like corresponding to the shapes, materials and uses of the tubular bodies.

일정한 길이로 제작된 관체를 수밀성이 유지되게 연결 접속함에 있어서는 각 관체들의 연접 단면을 서로 맞대어 체결함으로서 조립시키는 것이 가장 바람직한 방법이기는 하나 이 방법은 설치현장에서 직접 체결하는 작업 그 자체에 상당한 번거로움과 어려움이 수반된다.It is the most preferable method to assemble the tubular body made of a certain length by fastening the connecting sections of the tubular bodies against each other in the connecting connection box in which the watertightness is maintained. However, this method requires considerable troubles It is accompanied by difficulties.

또한, 합성수지 관체가 외면이 평활한 일반 관이 아니라 나선관인 경우 그 양 접속부위의 단면이 수직 절단면으로 가공되지 못하고 나선형상에 대응하는 절곡 절단면으로 가공될 수 밖에 없어 이의 연결은 더욱 불안정한 것이어서 이를 접속시킴에 있어 상당히 까다롭고 번거로운 작업성이 요구되는 것이었다.In addition, when the synthetic tube body is a spiral tube rather than a plain tube whose outer surface is smooth, the cross-section of both connection portions can not be processed into a vertical cut surface, but is formed into a bent cut surface corresponding to the spiral shape. Thus, the connection is more unstable, It was very demanding and troublesome workability in Sikkim.

이에 종래에는 복수의 나선관 양단을 서로 맞대기 한 후 외주면에 밀봉시트를 감싸고 밀봉시트의 외주면에 금속 밴드를 체결하여 나선관들을 연결하는 나선관 연결용 금속 밴드가 이용되고 있다.Conventionally, a metal band for connecting a spiral tube is used in which both ends of a plurality of helical tubes are butted together, a sealing sheet is wrapped around the outer circumferential surface, and a metal band is fastened to the outer circumferential surface of the sealing sheet to connect the helical tubes.

상기 나선관 연결용 금속 밴드는 스테인리스 재질로 이루어져 상기 밀봉시트의 외주면을 감싸도록 설치되며, 상기 밀봉시트의 폭과 동일하거나 넓은 폭을 갖는 판체 형상의 본체와, 상기 본체의 일측 단부 및 중단에 각각 설치되고 고정볼트가 관통하여 조여지는 다수의 볼트구멍이 형성된 연결판을 포함한다.Wherein the metal band for connecting the spiral tube is made of stainless steel and surrounds the outer circumferential surface of the sealing sheet and has a plate-shaped body having a width equal to or wider than the width of the sealing sheet, And a connecting plate provided with a plurality of bolt holes which are fastened through the fixing bolts.

그러나, 종래의 금속 밴드는 고정볼트와 같은 체결수단의 조임력을 균등하게 하지 않으면 밀봉시트의 조임력 또한 상실됨에 따라 수압에 의해 복수의 나선관 사이의 틈새로 인하여 누수가 발생하는 문제점이 있었다.However, in the conventional metal band, if the tightening force of the fastening means such as the fixing bolt is not made uniform, the tightening force of the sealing sheet is also lost, and there is a problem that leakage occurs due to a gap between the plural spiral tubes due to water pressure.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 복수의 나선관 연결 시 나선관의 절단부 피치와 동일한 피치를 갖는 슬리브패킹을 각 나선관의 절단면에 밀착 결합함으로써 기밀성 및 수밀성을 향상시킬 수 있는 나선관용 연결장치를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been conceived to solve the problems described above, and it is an object of the present invention to improve the airtightness and the watertightness by tightly fitting the sleeve packing having the same pitch as the cut portion pitch of the helical tube to the cut surface of each helical tube, The present invention provides a connecting device for a spiral tube.
