나선형 파형관용 이음장치{APPARATUS FOR CONNECTION SPIRAL CORRUGATED PIPES}Spiral corrugated pipe joints {APPARATUS FOR CONNECTION SPIRAL CORRUGATED PIPES}

본 발명은 나선형 파형관용 이음장치에 관한 것으로, 구체적으로 지중관로의 이음시 이음부 결합과 동시에 나선파형관을 접속하는 나선형 파형관용 이음장치에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spiral corrugated pipe joint, and more particularly, to a spiral corrugated pipe joint for connecting spiral waved pipes at the same time as joints of a underground pipe.

지중관로는 맨홀 또는 변전소 사이를 연결시 지하수 및 외부영향으로부터 전력선을 안정적으로 보호하기 위한 것이다. 상기 지중 관로는 주로 외부면이 주름지게 형성된 파형관(wave tube) 형태의 매립관과 맨홀의 벽면에 설치한 플랜지형의 평관(flat tube) 형태의 관로구를 이음 작업하여 맨홀과 맨홀 사이를 연결하는 방식으로 시공한다.Underground pipelines are designed to reliably protect power lines from groundwater and external influences between manholes or substations. The underground pipe line is a method of connecting the manhole and the manhole by connecting a buried pipe having a corrugated outer surface with a corrugated outer surface and a pipe tube having a flange-like flat tube installed at the wall of the manhole. Construct with

파형관은 하중 및 반력이 관둘레에 균등하게 분포되어 내하력이 커서 수로, 통로,기타 각종 구조물에 사용된다. 또한 파형관은 경량으로 취급이 용이하므로 조립과 시공이 모두 간단하고 경제적이다. 또한 파형관은 용융아연도금 강판을 사용 하기 때문에 부식에 강하고 수명이 긴 장점이 있다.Corrugated pipe is used in channel, passage, and other structures because load and reaction force are distributed evenly around the pipe. In addition, since the corrugated pipe is light and easy to handle, both assembly and construction are simple and economical. In addition, the corrugated pipe has advantages of being resistant to corrosion and having a long life because it uses hot-dip galvanized steel sheet.

종래의 파형관 연결장치는 파형관끼리의 접속시에는 연결하고자 하는 관로들을 서로 맞대어 그 위에 연결 슬리브를 결합한다. 관로를 슬리브 결합한 후 1차로 실링테이프로 감고 2차로 테이프를 감는다. 또한 2차 테이프 작업 후, 3차로 비닐테이프로 감아서 마감하는 테이프 방식을 사용한다.In the conventional corrugated pipe connecting device, when the corrugated pipes are connected to each other, the connecting sleeves are coupled to each other to couple the connecting sleeve thereon. After sleeve coupling the pipeline, the first winding with sealing tape and the second winding tape. In addition, after the second tape work, the tape method to finish by winding the third tape with vinyl tape.

또는 파형관을 연결하기 위하여 파형관 골 위에 고무패킹을 양쪽에 각각 올려놓고 고무관을 덮은 뒤 고무관 위에 밴드관을 씌워 볼트로 체결하는 조립식 이음장치에 의한 방식을 사용한다. 그러나, 상기와 같은 파형관 연결방법은 누수의 위험이 클 뿐만 아니라, 작업시간이 오래걸리는 문제점이 있다. Alternatively, in order to connect the corrugated pipe, the rubber packing is placed on each side of the corrugated pipe, and the rubber pipe is covered on both sides, and then the banded pipe is covered on the rubber pipe and the bolted joint is used. However, the corrugated pipe connection method as described above not only has a high risk of leakage, but also takes a long time.

본 발명은 이와 같은 문제를 해소하기 위해 마련한 것으로, 본 발명의 목적은 서로다른 파형관을 연결하며 누수 및 외부요인으로부터 관로내부를 보호할 수 있는 나선형 파형관용 이음장치를 제공하는 것을 기술적 목적으로 한다.

본 발명은 파형관 단면 방향으로 회전결합함으로써 별도의 결합도구 없이도 결합력 및 시공성을 향상시킨다. The present invention improves the bonding force and workability by rotating coupling in the cross-sectional direction of the corrugated pipe without a separate coupling tool.

또한 파형관과 나선형 파형관용 이음장치 사이에 패킹재를 설치하여 누수를 효과적으로 방지한다.In addition, a packing material is installed between the corrugated pipe and the spiral corrugated pipe joint to effectively prevent leakage.

또한 패킹이 눌러주는 결합력을 이용하여 동절기 작업시 심하게 휘어진 파형관의 결합시공성을 향상시킨다. In addition, by using the bonding force pressed by the packing to improve the bondability of the corrugated pipe bent badly during the winter work.

본 발명은 제 1 이음부 및 제 2 이음부(200)를 포함하여 2개의 원통모양의 나선형 파형관용 이음장치를 포함한다. The present invention includes two cylindrical spiral corrugated pipe joints including a first joint portion and a second joint portion 200.

본 발명은 파형관의 외주면과 결합하는 내주면의 나선방향이 파형관과 동일한 결합부(110,210)와 상기 파형관의 나선방향과 반대방향을 가지며 상기 결합부를 연결하도록 하는 암나사부(220) 및 수나사부(210)를 포함하도록 구성된다.According to the present invention, the spiral direction of the inner circumferential surface coupled to the outer circumferential surface of the corrugated pipe has the same coupling parts 110 and 210 as the corrugated pipe and the opposite direction to the spiral direction of the corrugated pipe, and the female screw part 220 and the male screw part 210 connect the coupling part. It is configured to include.

제 1 이음부(100)와 제 2 이음부(200)를 제 1, 2 파형관(10,11)과 연결하면, 제 1 파형관(10)-결합부(110)-수나사부(210),암나사부(220)의 연결부(이하, 연결부(300))-결합부(210)-제 2 파형관(11)순으로 연결된다. When the first joint part 100 and the second joint part 200 are connected to the first and second corrugated pipes 10 and 11, the first corrugated pipe 10-the coupling part 110-the male thread part 210 and the female thread The connecting portion (hereinafter, the connecting portion 300) of the unit 220 is connected in the order of the coupling portion 210-the second corrugated pipe (11).

상기 연결부(300)로 인하여 상기 제 1,2 이음부는 서로 다른 방향으로 회전 시켜 3부분에서 파형나선을 따라 결합한다. Due to the connection part 300, the first and second joints are rotated in different directions to be coupled along the wavy spiral in three parts.

제 1 이음부와 제 2 이음부가 결합된 부분, 즉 연결부(300)는 파형관의 나선방향과 반대방향으로 한쪽은 외주면, 반대쪽은 내주면으로 나선파형을 구성한다.The portion where the first joint portion and the second joint portion are coupled, that is, the connecting portion 300, forms a spiral waveform on one side of the outer circumference and the other side of the inner circumferential surface in the opposite direction to the spiral direction of the corrugated pipe.

제 1 이음부의 결합부(110)와 제 2 이음부의 결합부(210)가 서로 마주보면서 진행하여 결합하는 구성이다. 이때, 연결부(300)의 나선은 파형관의 결합부 진행속도와 동일하게 나사선의 간격을 조정하여야 한다. 또한 누수방지를 위한 정밀한 설계가 필요하다.The coupling portion 110 of the first joint portion and the coupling portion 210 of the second joint portion is configured to proceed by facing each other. At this time, the spiral of the connecting portion 300 should adjust the spacing of the screw thread to the same as the speed of the coupling portion of the corrugated pipe. In addition, precise design to prevent leakage is required.

On the other hand, the coupling portion 110, 210 to form a groove 111 or a protrusion in one embodiment. A tool for joining the joint can be inserted through the groove formed in the joining surface. For example, a wrench or a hand tool may be inserted into the groove 111 so that the curved corrugated pipe can be straightened or a joint can be conveniently connected.

도 5는 파형관 외주면에 패킹재를 설치한 단면도 도시한다.5 is a cross-sectional view showing a packing material on the outer circumferential surface of the corrugated pipe.

도 5에 따르면, 본 발명은 파형관의 단면방향으로 나선형으로 결합된 부분외에는 외부에 노출되는 부분이 없어 누수 발생 위험이 낮다. 그러나 제 1,2 이음부에는 누수의 위험이 존재하여 이를 보안하기 위하여 패킹재를 설치한다. According to FIG. 5, the present invention has a low risk of leakage since there is no part exposed to the outside except a part spirally coupled in the cross-sectional direction of the corrugated pipe. However, there is a risk of water leakage in the first and second joints, and the packing material is installed to secure it.

패킹재(400)는 파형관 입구에서 멀어지면서 두께가 두꺼워지는 형태를 취한다. 따라서 제 1,2 이음부의 연결시 지렛대 역할을 할 수 있다. 즉, 패킹재(400)는 제 1, 2 파형관(10,11) 입구의 두께는 얇고, 연결부(300)쪽으로 갈수록 두께가 두껍게 형성한다. 패킹재가 삽입된 연결부에 압력을 주어 더욱 강하게 패킹되도록 하여 누수의 위험을 막을 수 있다. The packing material 400 has a form in which the thickness becomes thick while moving away from the inlet of the corrugated pipe. Therefore, it can act as a lever when connecting the first and second joints. That is, the packing material 400 has a thin thickness at the inlet of the first and second corrugated pipes 10 and 11, and becomes thicker toward the connection part 300. The pressure is applied to the connection portion in which the packing material is inserted so that the packing is made stronger, thereby preventing the risk of leakage.

패킹재는 신축 및 압축성이 뛰어난 연성재질을 사용하도록 한다. Packing material should be flexible material with excellent stretching and compressibility.

본 발명은 결합부와 암나사부가 일체로 구성된 제 1 이음부와 결합부와 수나사부가 일체로 구성된 제 2 이음부를 이용하여 파형관을 연결한다.The present invention connects the corrugated pipe using a first joint portion having a coupling portion and a female thread portion integrally and a second joint portion having a coupling portion and a male thread portion integrally.

서로 다른 파형관과 연결부사이에 패킹재를 삽입하도록 함으로써 누수를 방지할 수 있다. Leakage can be prevented by inserting a packing material between different corrugated pipes and connecting portions.

또한, 결합부에 형성한 홀을 통하여 수공구를 삽입하여 휘기 쉬운 파형관을 직선으로 펼 수 있도록 한다는 점에서 기술적 특징은 매우 명확하다.In addition, the technical feature is very clear in that it is possible to straighten the flexible tube by inserting the hand tool through the hole formed in the coupling portion.
