합성수지제 나선관의 관 접속구Pipe end of synthetic resin spiral pipe

제1도는 접착제 도포부위를 예시한 합성수지제 나선관의 예시도.1 is an illustration of a synthetic resin spiral tube illustrating the adhesive coating site.

제2도는 본 고안에 의한 관 접속구를 이용한 접속상태의 확대 발췌 단면도.Figure 2 is an enlarged cross-sectional view of the connection state using the tube connection according to the present invention.

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1, 1': 합성수지제 나선관 1a : 골1, 1 ': synthetic resin spiral tube 1a: bone

2 : 접속구 3, 3': 실란트2: connector 3, 3 ': sealant

본 고안은 합성수지제 나선관을 접속하기 위한 관 접속구의 개량에 관한 것이며, 특히 나선관을 접합 했을때 이음새가 긴밀하고 이 부분의 내압강도가 높으며, 또한 관 접속이 용이한 새로운 구조의 관 접속구에 관한 것이다.The present invention relates to the improvement of the pipe connection for connecting a spiral pipe made of a synthetic resin, and especially to the connection of a new structure in which a splice is tight, the pressure resistance of this part is high, and the pipe connection is easy. It is about.

나선관용 관 접속구는 나선관의 요철상 외주면에 부합되는 요철상 내주면을 갖는 것이 이상적이라는 사실은 이미 주지되어 있다. 그 대표적인 예로서 실용신안공고 제85-1102호가 있다.It is already known that spiral tube fittings should ideally have an uneven inner circumferential surface that matches the uneven outer circumferential surface of the spiral tube. As a representative example thereof, Utility Model Publication No. 85-1102 is disclosed.

이 관 접속구는 그 내주면과 나선관의 외주면 사이에 소정의 틈새를 남길만한 규정칫수를 갖고 있으며, 나선관 접속시에 생기는 그 틈새로 발포수지를 충전 발포시키고 그 팽창 충전에 의해 틈새가 메꿔지므로서 접속부의 기밀성이 보지되도록 하는데 근본적인 의의를 찾을 수 있다.This pipe fitting has a specified dimension to leave a predetermined gap between its inner circumferential surface and the outer circumferential surface of the spiral pipe.The gap between the spiral pipe connection and the filling is filled with foamed resin and the gap is filled by the expansion filling. A fundamental significance can be found in ensuring the confidentiality of connections.

그러나 상기한 바와 같은 종래의 관 접속구를 이용하여 나선관을 접속하는 경우 지반의 형태, 굴삭의 정밀도 그리고 작업자의 숙련도 따위가 변수로 작용해 자칫 관 접속상태가 부실해질 우려가 많았고, 또한 지하에 매설했을 때에는 관 접속부도 토압을 받게 되는데 상기 발포수지층은 다른 부위에 비해 유연하고 취성이 강하므로 쉽게 파괴될 우려 또한 컸다.However, in the case of connecting the spiral pipe using the conventional pipe connection as described above, there are many concerns that the connection status of the pipe will be poor due to the shape of the ground, the accuracy of the excavation, and the skill of the operator. When the pipe joint is also subjected to earth pressure, the foamed resin layer is more brittle and brittle than other parts, so it is also easy to break.

그러한 경향은 차동상에 매설한 경우에 특히 심하다. 정합과 함께 차량 진동등에 의한 등압의 복합적 영향으로 말미암아 내압력이 저하되기 때문이다. 더우기 주지의 발포 수지에 의한 관 접속부의 기밀성 강화수단은 이 발포수지가 이것과 성질을 달리하는 합성수지제 나선관 및 관 접속구와의 사이에 친화력이 없거나 극히 작기 때문에 접속후 약간의 외력을 받는다든지 혹은 기온변화로 인해 이완될 우려가 크고, 따라서 누수를 방지 하는데는 비효과적이었다.Such a tendency is especially severe when embedded in the differential phase. This is because the internal pressure decreases due to the combined effect of the isostatic pressure caused by the vibration of the vehicle together with the matching. Moreover, the airtightness reinforcing means of the pipe joint by the known foam resin has a slight external force after connection because the foamed resin has no affinity or extremely small affinity between the synthetic resin spiral pipe and the pipe joint. There is a high possibility of relaxation due to temperature changes, and thus ineffective in preventing leakage.

본 고안은 바로 상기한 바와 같이 발포수지를 이용하는 관 접속구의 문제점을 극복할 수 있는 신규의 관접속구를 제공하려고 안출한 것으로서, 이하 첨부도면과 관련지어 보다 상세하게 설명한다.The present invention has been made to provide a novel connector that can overcome the problem of the tube using a foam resin as described above, will be described in more detail in connection with the accompanying drawings.

관 접속구(2)는 통상의 합성수지제 나선관(1)의 요철상 외주면에 부합되도록 요철상의 내면을 지니고 있으며, 그 내면은 접속한 나선관(1)의 재질과 그리고 접착제와의 친화성이 강한 실란트(3)가 도포되어 있다.The pipe joint 2 has an uneven inner surface so as to conform to the uneven outer circumferential surface of the conventional synthetic resin spiral tube 1, and its inner surface has a strong affinity with the material of the connected spiral tube 1 and the adhesive. The sealant 3 is applied.

그리고 합성수지제 나선관(1)은 그 양단부에서 일정 칫수 범위(A)읠 골(1a)에만 상기와 같은 성질의 실린트(3')가 도포되어 있다.In the spiral tube 1 made of synthetic resin, a sealant 3 'having the same property as described above is coated only at a certain dimension (A) 읠 bone 1a at both ends thereof.

상기 실란트(3)(3')의도포 두께는 균일하다.The coating thickness of the sealant 3, 3 'is uniform.

이와 같은 구성요소로 이뤄진 본 고안을 이용하여 합성수지제 나선관을 접합하는 방법에 대하여 설명하면, 전과 같은 요령으로 양단부의 규정 칫수범위(A)의 골(1a)에 실란트(3')가 도포된 나선관(1)의 그 일측 단부에 역시 그 요철상 내면에 실란트(3)가 도포된 관 접속구(2)를 반쯤 나사끼움하여 접합한 다음 나머지 반부분에 다른 나선관(1')의 일측 단부를 나사기움하여 긴밀히 접속하는 것만으로써 관과 관을 잇는 관 접속이 마무리 되는 것이다.Referring to the method of joining the synthetic resin spiral tube using the present invention made of such components, the sealant (3 ') is applied to the bone (1a) of the specified dimension range (A) of both ends in the same way as before. One end of the helix tube 1 is half-screwed to the tube connector 2 with the sealant 3 coated on the inner surface of the spiral tube 1, and then the other half of the one end of the other spiral tube 1 '. The screw connection between the pipe and the pipe can be completed by simply screwing closely.

이상과 같은 본 고안에 있어서, 합성수지제 나선관의 접속부는 관접속구와의 틈새가 친화성을 가진 실린트와 접착제에 의해 완전히 밀봉되는 또한 강력하게 접합되어 관접속 강도가 매우 크므로 이 부분에서의 외력에 의한 내구력이 대폭 보강됨은 물론 수밀성 향상에도 기여하는 바가 크다.In the present invention as described above, the connection part of the synthetic resin spiral pipe is completely sealed by the affinity sealant and the adhesive and the joint is tightly joined, so that the connection strength is very large. Durability due to external force is greatly strengthened and contributes to improving watertightness.

뿐만 아니라 관접속 시공도 한결 수월해서 현장 시공능률이 진작되므로 공기 단축은 물론 염가 시공이란 편익도 제공할 수가 있는 것이다.In addition, the pipe construction is much easier, and the site construction efficiency is improved, so that the air shortening and the cheap construction can be provided.
