도 2는 본 발명에 의한 배관 연결용 고무링의 사시도이고, 도 3 및 도 4는 본 발명의 배관 연결용 고무링의 사용상태를 도시한 단면도.Figure 2 is a perspective view of the rubber ring for pipe connection according to the present invention, Figure 3 and Figure 4 is a cross-sectional view showing a state of use of the rubber ring for pipe connection of the present invention.

본 발명에 의한 단차제거링이 구비된 이중벽관은 도 2에 도시한 바와 같이 탄성이 있는 고무 또는 합성수지로 성형된 단차제거링(100)이 구비된것으로서, 상기 단차제거링(100)은 환형의 형태를 가지고, 단면형상이 삼각형태인 돌출부(101)와, 상기 돌출부(101)의 양측에 날개부(102)가 형성된다.Double wall tube with step removal ring according to the invention is provided with a step removal ring 100 formed of elastic rubber or synthetic resin as shown in Figure 2, the step removal ring 100 is of an annular shape It has a form, the projection 101 having a triangular cross-sectional shape, and the wing portion 102 is formed on both sides of the projection 101.

상기와 같이 구성된 단차제거링(100)을 연결관(12)의 소켓부(13)에 삽입하고, 상기 연결관(12)의 소켓부(13)에 삽입관(11)을 삽입하면 도 3와 같다.When the step removal ring 100 configured as described above is inserted into the socket part 13 of the connection pipe 12 and the insertion pipe 11 is inserted into the socket part 13 of the connection pipe 12 and FIG. same.

일반적으로 하수관은 상수관과 달리 배관 내부에 내압이 크게 작용하지 않으므로 도 3에 도시한 바와 같이 연결관(12)의 단부가 확대되어 소켓부(13)가 형성되고, 상기 소켓부(13)에 삽입관(11)의 단부가 삽입되어 연결되도록 구성되는데, 본 발명의 단차제거링(100)을 상기 소켓부(13)에 삽입한 후 삽입관(11)을 소켓부(13)에 삽입하면 도 4에 도시한 바와 같이, 단차제거링(100)의 돌출부(101)가 삽입관(11)의 단부와 연결관(12)의 경사진 소켓부(13) 내벽에 밀착되고, 상기 돌출부(101)의 양측에 형성된 날개부(102)가 각각 삽입관 (11)및 연결관(12)의 내벽에 밀착된다.In general, sewage pipes do not have a large internal pressure inside the pipes, unlike water pipes, as shown in FIG. 3, the ends of the connection pipes 12 are enlarged to form a socket 13, and the socket 13 An end of the insertion tube 11 is configured to be inserted and connected, and when the step removal ring 100 of the present invention is inserted into the socket portion 13, the insertion tube 11 is inserted into the socket portion 13. As shown in FIG. 4, the protrusion 101 of the step removing ring 100 is in close contact with the end of the insertion tube 11 and the inner wall of the inclined socket portion 13 of the connecting tube 12. Wings 102 formed on both sides of the close contact with the inner wall of the insertion tube 11 and the connection tube 12, respectively.

상기와 같이 삽입관(11)의 단부와 소켓부(13)의 내벽에 돌출부(101)가 밀착되고, 삽입관(11) 및 연결관(12)의 내벽에 날개부(102)가 밀착됨으로써 하수관을 흐르는 하수가 배관 연결부인 소켓부(13)에서 새지 않게 되어 수밀이 보장되는 것이다.As described above, the protrusion 101 is in close contact with the end of the insertion pipe 11 and the inner wall of the socket 13, and the wing 102 is in close contact with the inner wall of the insertion pipe 11 and the connection pipe 12. The sewage flowing through is not leaking from the socket portion 13 which is a pipe connection portion is to ensure watertight.

이때, 소켓부(13)에 삽입되기 전의 단차제거링(100) 날개부(102) 끝단 외경(RD)은 삽입관(11) 및 연결관(12)의 내경(RP)보다 3%~10%정도 다소 크게 성형함으로써, 본 발명의 고무링(100)을 소켓부(13)에 장착하였을 때, 날개부(102)가 연결관(12) 및 삽입관(11)의 내벽에 강하게 밀착되어 수밀성을 높이도록 하는 것이 바람직하다.At this time, the outer diameter (R D ) of the end of the step removing ring (100) and the wing portion (102) before being inserted into the socket portion (13) is 3% to the inner diameter (R P ) of the insertion pipe (11) and the connection pipe (12). When the rubber ring 100 of the present invention is mounted to the socket portion 13 by forming a somewhat larger 10%, the wing portion 102 is strongly adhered to the inner walls of the connecting pipe 12 and the insertion pipe 11. It is desirable to improve water tightness.

또한, 상기 단차제거링(100)의 내측 가운데가 볼록한 곡선의 형상 즉, 고무링(100)의 날개부(102) 가운데 부분의 내경이 외측으로 갈수록 점점 커지도록 구성함으로써, 배관의 내벽에 단차가 생기지 않도록 하여 배관을 흐르는 하수가 원활하게 흐르도록 하는 것이 바람직하다.In addition, the inner center of the step removal ring 100 is formed in a convex curve, that is, the inner diameter of the center portion of the wing portion 102 of the rubber ring 100 is configured to increase gradually toward the outside, so that the step on the inner wall of the pipe It is preferable that the sewage flowing through the pipe flows smoothly so as not to be generated.

상기 단차제거링(100)의 가운데 내측 부분이 볼록한 즉, 두께가 두꺼운 이유는 토압에 의해 삽입관(11)과 연결관(12)의 유격이 발생하였을 때 날개부(102)와 돌출부(101)가 접하는 부분이 쉽게 파손되지 않도록 하기 위하여 가운데 부분의 두께가 두껍게 구성된 것이다.The inner part of the step removal ring 100 is convex, that is, the reason why the thickness is thick when the clearance between the insertion pipe 11 and the connection pipe 12 is generated by the earth pressure wing 102 and the protrusion 101 The thickness of the middle part is thick so that the contact part is not easily broken.

또한, 상기 단차제거링(100)의 날개부(102) 양 끝단의 두께가 얇은 이유는 날개부(102) 끝단에 단차가 생겨 하수의 흐름을 방해할 수 있기 때문에, 날개부(102) 양 끝단의 두께를 얇게 함으로써 단차가 생기지 않도록 하여서 하수가 원활하게 흐르도록 하기 위함이다.In addition, the reason why the thickness of both ends of the wing 102 of the step removal ring 100 is thin because a step may occur at the end of the wing 102, thus preventing the flow of sewage, both ends of the wing 102. This is to allow the sewage to flow smoothly by reducing the thickness of the step so that a step does not occur.

상기와 같이 소켓부(13)에 삽입된 배관 연결용 단차제거링(100)은 토압에 의해 배관이 소정각도 꺽이더라도 수밀성능을 유지할 수 있다.As described above, the step removal ring 100 for pipe connection inserted into the socket 13 may maintain the watertight performance even if the pipe is bent at a predetermined angle by earth pressure.

도 5에 도시한 바와 같이 토압에 의해 배관이 소정각도(α)로 꺽이면, 소켓부(13)의 일측 삽입관(11)이 소켓부(13)에서 빠져나오게 되면서 유격이 발생하게 되는데, 본 발명의 고무링(100)은 상기와 같이 토압에 의해 배관이 꺽여 소켓부(13)에서 삽입관이 빠지면서 유격이 발생하더라도 날개부(102)가 연결관(12)과 삽입관(11)의 내벽에 밀착되어 있기 때문에 하수가 외부로 새지 않게 된다.As shown in Figure 5, when the pipe is bent at a predetermined angle (α) by the earth pressure, one side insertion pipe 11 of the socket portion 13 is released from the socket portion 13, the play is generated. Rubber ring 100 of the invention is the inner wall of the connecting pipe 12 and the insertion pipe 11, even if the clearance is generated while the insertion pipe is pulled out of the socket portion 13 by the earth pressure as described above. Because it is in close contact, the sewage does not leak to the outside.

즉, 본 발명은 토압에 의해 배관이 꺽이더라도 완벽하게 수밀성능을 유지할 수 있는 것이다.That is, the present invention can maintain the watertight performance perfectly even if the pipe is bent by the earth pressure.

이상, 본 발명에 의한 단차제거링이 구비된 이중벽관에 대해 설명하였다. 상기 본 발명의 기술적 구성은 본 발명이 속하는 기술분야의 당업자가 그 기술적 사상이나 필수적 특징을 변경하지 않고서 다른 구체적인 형태로 실시될 수 있다는 것을 이해할 수 있을 것이다.In the above, the double-walled tube provided with the step removal ring according to the present invention has been described. The technical configuration of the present invention will be understood by those skilled in the art that the present invention can be implemented in other specific forms without changing the technical spirit or essential features.

그러므로, 이상에서 기술한 실시 예들은 모든 면에서 예시적인 것이며 한정적인 것이 아닌 것으로서 이해되어야 하고, 본 발명의 범위는 전술한 상세한 설명보다는 후술하는 특허청구범위에 의하여 나타내어지며, 특허청구범위의 의미 및 범 위 그리고 그 등가 개념으로부터 도출되는 모든 변경 또는 변형된 형태가 본 발명의 범위에 포함되는 것으로 해석되어야 할 것이다.Therefore, the above-described embodiments are to be understood in all respects as illustrative and not restrictive, and the scope of the present invention is indicated by the appended claims rather than the foregoing description, and the meanings of the claims and All changes or modifications derived from the scope and equivalent concepts thereof should be construed as being included in the scope of the present invention.
