본 고안은 관벽살의 보강 및 변형방지를 목적으로 하는 합성수지제 이음관에 관한 것이다.The present invention relates to a synthetic resin joint pipe for the purpose of reinforcing the pipe wall and preventing deformation.

합성수지제 이음관의 제질은 사용용도 등에 따라 특별히 선정되지만 일반적으로 알려진 것으로는 P.V.C와 P.E 그리고 P.P 등이다.The quality of the synthetic resin pipe is selected according to the purpose of use, but generally known are P.V.C, P.E and P.P.

그런데 합성수지제 이음관이 갖고 있는 최대의 결점은 온도, 외력에 대한 내부응력이 낮아 수축, 팽창 등 변형율이 매우 높고 또한 쉽게 파괴된다는 점이다. 수축, 팽창 등 변형율이 높으면 상대적으로 관이음 후에 기밀누설이라든가 이완 등의 불안요안이 증대되는 중대결과를 초래할 수도 있기 때문에 이음관 자체의 변형에 대한 대응력을 키우는 것은 매우 중요한 일이라 하겠다.However, the biggest drawback of synthetic resin fittings is that the internal stress against temperature and external force is low, so the deformation rate such as shrinkage and expansion is very high and it is easily destroyed. High strains such as shrinkage and expansion may cause significant consequences such as increased leakage or relaxation after pipe joints. Therefore, it is important to increase the ability to cope with deformation of the joint pipe itself.

본 고안은 바로 이와 같은 기대에 부응하기 위해 착안한 것으로, 이음관의 구부쪽 관벽살 내부에 링형상의 철제 심재를 매입하여 강도를 높인 것이 주된 요지이다.The present invention was conceived to meet such expectations, and the main point is to increase the strength by purchasing a ring-shaped iron core inside the bent side wall of the joint pipe.

다음에 본 고안을 실시예에 의거 작성한 도면을 참조하여 구체적으로 기술한다.Next, the present invention will be described in detail with reference to the drawings created based on the embodiments.

통상의 합성수지제 이음관에서 관벽살(1) 내부에 두께 2∼3mm의 철제 링으로 된 심재(2)가 대체로 관벽살(1)의 단면중앙에 그리고 관체와 동심원상에 매입되어 있고, 그 대입 위치는 관벽살(1)의 구부(5)쪽에 치중하는 것을 원칙으로 하지만 필요에 따라 관벽살(1) 전체에 걸쳐 실시할 수도 있다.In ordinary synthetic pipe joints, the core material 2 of steel rings having a thickness of 2-3 mm inside the tube wall 1 is generally embedded in the center of the cross section of the tube wall 1 and concentrically with the tube body. In principle, the position is centered on the bent portion 5 of the tube wall 1, but may be carried out throughout the tube wall 1 as necessary.

심재(2)의 주면에는 통공(3)이 등간격으로 뚫려 있다. 이 통공(3)으로는 사출 성형시 관벽살(1)을 구성하는 수지가 메워져서 심재(2)를 경계로 할 때 안팎의 관벽살을 서로 이어서 심재(2) 매입으로 야기될 관벽살(1)의 강도 저하를 막아줄 뿐만 아니라 관벽살(1) 내에서 심재(2)의 유동을 방지하는 스토퍼 구실도 하게된다.A through hole 3 is drilled at equal intervals on the main surface of the core material 2. The through-holes 3 are filled with the resin constituting the tube wall 1 during injection molding, and when the core 2 is bounded by the inner and outer tube walls, the tube wall to be caused by the purchase of the core 2 is formed. In addition to preventing the decrease in strength, the stopper serves to prevent the flow of the core material 2 in the tube wall 1.

심재(2)의 외주면에서는 역시 동간격으로 밸런스 핀(4)이 돌출되게 형성되어 있다. 이 밸런스 핀(4) 돌출높이는 관벽살(1)의 외경과 같은 조건을 구비하며, 사출 성형시 심재(2)가 관체와 동심원상에 정확히 놓이도록 균형을 잡기 위해 마련된 것이다.On the outer circumferential surface of the core material 2, the balance pin 4 protrudes at equal intervals. The projecting height of the balance pin 4 has the same condition as the outer diameter of the tube wall 1, and is provided to balance the core material 2 so as to lie exactly on the concentric body with the tube during injection molding.

사출 성형시 상기 밸런스 핀(4)의 끝은 외측 급형의 내면에 맞닿아서 전술한 바와 같은 심재(2)의 균형을 유지하게 된다.In injection molding, the tip of the balance pin 4 abuts on the inner surface of the outer mold to maintain the balance of the core 2 as described above.

이상과 같은 본 고안은 이음관체의 관벽살 내에 관형태의 철제 링으로 된 심재를 매입함으로써 강도가 증대되어 외력에 의한 수축, 팽창 등의 변형이 대폭 감소될 뿐 아니라 심재 주면에 형성된 통공에 의한 관벽살 내에서의 심재의 유통방지 및 밸런스 핀에 의한 심재의 매입 급형이 유지되어 고품질의 합성수지제 이음관을 제공할 수가 있다.The present invention as described above is to increase the strength by embedding the core material of the tubular iron ring in the pipe wall of the joint pipe body not only greatly reduces the deformation, expansion, etc. due to external force, but also through the hole formed in the core surface It is possible to provide a high quality synthetic resin fitting pipe by preventing the distribution of the core material in the wall and the feeding of the core material by the balance pin.
