걸고리식 이중벽체나선관Hook-type double wall spiral pipe

본발명은 오수나 생활하수 등의 배수를 위하여 지중에 매설되는 나선관에 관한 것으로, 특히 관체부를 이루는 내벽체의 단면구조를 개선시켜주는 동시에 그 내벽체와 외벽체 상호간의 일체성을 증대시켜주는 걸고리식 이중벽체나선관에 관한 것이다.The present invention relates to a spiral pipe embedded in the ground for drainage of sewage or domestic sewage, and in particular, improves the cross-sectional structure of the inner wall of the pipe and increases the integrity of the inner wall and the outer wall. It is related with type double wall spiral pipe.

이전부터 하수 및 오수를 배수처리하기 위하여 지중매설되는 매설관으로서 합성수지나선관이 사용되고 있는 바, 이러한 합성수지나선관 중 대표적인 것으로 국내특허공보 89-1842호에는, 관벽을 나선파형으로 형성하되, 나선파형중 정상부와 이 정상부에 연결되는 양측벽부의 일부에 걸쳐서 금속박판이 일체적으로 매립되도록 하여 만들어지는 지중매설용 내압합성수지관이 제안된 바 있다.In the past, synthetic resin spiral pipes have been used as underground buried pipes for draining sewage and sewage. In Korean Patent Publication No. 89-1842, the pipe wall is formed in a spiral wave shape, There has been proposed a pressure-resistant resin pipe for underground embedding, which is made by integrally embedding a metal sheet over a middle portion and a part of both side wall portions connected to the top portion.

이러한 지중매설용 내압합성수지관은 하중저항 내력이 상대적으로 강한 금속박판이 그 중간부에 매설된 합성수지제의 판체가 나선형으로 감아져서 관체부를 이루는 구조를 가지기 때문에, 전반적으로 하중저항 내력이 향상되는 장점을 가지는 것이 사실이다.Since the pressure-resistant synthetic resin pipe for underground laying has a structure in which a thin metal plate having a relatively high load resistance strength is formed in the middle of the synthetic resin plate spirally wound to form a tubular portion, the overall load resistance strength is improved. It is true to have

그러나, 이와 같은 종래의 지중매설용 내압합성수지관은 합성수지제 판체에 매립되는 금속박판의 양측 끝부분들이 견고하게 연결되는 구조를 가지지 못하였기 때문에, 운송이나 시공중에 금속박판이 연결되는 부분에 우발적인 충격이나 하중을 받을 경우에, 금속박판의 연결부분이 파손되기 쉬운 결점이 있었다.However, such a conventional underground pressure-resistant resin tube for underground buried has a structure in which both ends of the metal sheet embedded in the synthetic resin plate is not firmly connected, it is accidental to the part where the metal sheet is connected during transportation or construction In the event of an impact or a load, the connection part of the metal sheet was easily broken.

이와 같은 내압합성수지관의 결함을 보완하기 위한 것으로 국내 특허공보 96-4548호에는 도1a에서와 같이, 양면에 접착성 합성수지가 일체로 도포되고, 그 일측 끝부분에는 받침고리부(120)가 그 타측 끝부분에는 걸침고리부(130)가 길이방향으로 형성되도록 가공된 코팅금속판(100)을 나선형으로 감을 때에, 그 받침고리부(120) 내에 걸침고리부(130)가 끼워져서 걸어물려지는 걸고리의 구조를 가지는 것에 있어서, 상기 걸고리는 받침고리부(120)의 내면으로 형성되는 받침요홈(120)내에 용융 합성수지(200)를 채운 후에, 걸침고리부(130)를 단순히 끼워서 형성되는 채움걸고리(140)의 구조를 가지도록 하여, 연결이음부가 걸고리의 형상을 유지하도록 하여서 우발적인 집중하중에 대항 저항내력을 향상시켜주는 장점을 가지는 걸고리식 나선관이 선출원 공고되어 있다.In order to compensate for the defects of the pressure-resistant synthetic resin tube, the domestic patent publication 96-4548, as shown in Figure 1a, the adhesive synthetic resin is integrally coated on both sides, the one end portion of the support ring 120 is At the other end, the hook ring 130 is hooked to the hook ring 130 by being caught in the support ring 120 when the coated metal plate 100 is spirally wound so that the hook ring 130 is formed in the longitudinal direction. In having a structure of, the hook is filled with the hook ring portion 130 is formed by simply inserting the hook ring 130 after filling the molten synthetic resin 200 in the support groove 120 is formed by the inner surface of the support ring (120) The hook type spiral tube having the structure of 140) has the advantage of improving the resistance strength against accidental concentrated load by maintaining the shape of the hook part. All.

한편, 상기한 종래의 걸고리식 나선관의 일실시예에 의하면 도1b에 도시되는 바와 같이, 복수개의 파형(150)들을 포함하도록 굴곡 가공되는 복수파형의 상기 코팅금속판(100)을 나선형으로 감아서 만들어지는 굴곡파형관부의 내면부에 그 면이 평탄한 내면수지층이 나선형으로 감겨져서 평탄관부(180)를 일체로 형성시킨 이중관으로 구성된 것으로 적시되어 있다.On the other hand, according to one embodiment of the conventional hook-type spiral tube as shown in Figure 1b, by winding the coated metal plate 100 of the plurality of waveforms that are bent to include a plurality of waveforms 150 in a spiral manner It is pointed out that the inner surface resin layer whose surface is flat is spirally wound on the inner surface portion of the curved wave shaped tube portion that is made of a double tube in which the flat tube portion 180 is integrally formed.

즉 이러한 걸고리식 나선관은, 파형(150)들이 굴곡 형성된 코팅금속판(100)을 나선형으로 감아서 만들어진 굴곡파형관부(외벽체)의 내면부에, 별도의 내면수지로서 형성된 평탄관부(내벽체)(180)를 일체로 형성시킨 이중관으로 구성됨으로써, 외부하중에 대한 저항능력을 더욱 향상시켜주면서도 그 평탄관부(180) 내부를 따라 흐르는 오수 및 하수를 원할하게 배수시켜주는 장점을 가지는 것이 사실이다.That is, such a hooked spiral tube is a flat tube portion (inner wall) formed as a separate inner surface resin on the inner surface portion of the curved wave shaped tube portion (outer wall) spirally wound around the coated metal plate 100 in which the corrugations 150 are formed. It is a fact that by having a double pipe formed integrally with 180, it has the advantage of smoothly draining the sewage and sewage flowing along the inside of the flat pipe portion 180 while further improving the resistance to external load.

그러나, 이는 상기 굴곡파형관부의 파형(150)에 집중하중이나 온도변화에 따른 신축력이 작용되면, 그 파형(150) 사이의 평탄관부(180)를 이루는 내면수지가 이를 감당하지 못하고 쉽게 파손됨으로써, 그 평탄관부(180) 내부를 따라 흐르는 오수 및 하수의 흐름을 방해하여 배수능력을 저하시키는 문제점이 있었으며,However, this is because when the concentrated load or the elastic force according to the temperature change is applied to the waveform 150 of the curved waveform tube portion, the inner resin forming the flat tube portion 180 between the waveform 150 can not easily handle it, it is easily broken, There was a problem in reducing the drainage capacity by disturbing the flow of sewage and sewage flowing along the flat pipe portion 180,

또, 상기 굴곡파형관부의 파형(150)에 집중하중이나 온도변화에 따른 신축력이 작용되면, 이질의 재료로서 서로 변형계수가 다른 굴곡파형관부와 평탄관부(180) 사이가 들떠서 벌어지면서 오히려 굴곡파형관부를 이루는 코팅금속판(100)을 훼손시키게 됨으로써, 걸고리식 나선관의 내구성을 크게 저하시키는 문제점 등이 있었다.In addition, when an elastic force according to a load or temperature change is applied to the waveform 150 of the curved waveform tube part, the curved waveform tube part is rather exaggerated as the heterogeneous material is separated between the curved waveform tube part and the flat tube part 180 having different deformation coefficients. By damaging the coating metal plate 100 to be made, there was a problem of greatly reducing the durability of the hook type spiral tube.

본발명은 외벽체와 상응하는 단면구조로서 내벽체를 이루도록 하되, 그 내벽체와 외벽체 상호간이 중첩되게 걸어물려져서 연결되도록 구성하여, 첫째 내벽체의 단면구조를 크게 개선시켜서 내구성 증대를 통한 제품의 신뢰성을 제고하여주며, 둘째 내,외벽체 상호간이 중첩되게 걸어물려지는 구조로서 일체성을 증대시켜서 고품질의 걸고리식 이중벽체나선관을 제공하는 데에 그 목적이 있다.According to the present invention, the inner wall is formed as a cross-sectional structure corresponding to the outer wall, but the inner wall and the outer wall are connected to each other by being interlocked so as to overlap each other. First, the cross-sectional structure of the inner wall is greatly improved, thereby increasing the reliability of the product through durability. The purpose is to provide a high quality hooked double wall spiral tube by increasing the unity as a structure in which the inner and outer walls are interlocked to overlap each other.
