Description
제1도는 본 고안의 일부를 절개한 사시도.1 is a perspective view of a portion of the present invention cut.
제2(a)도는 고안의 요부 확대 단면도, 제2(b)도는 본 고안의 다른 실시예의 요부 확대 단면도.Figure 2 (a) is an enlarged cross-sectional view of the main part of the invention, Figure 2 (b) is an enlarged cross-sectional view of the main portion of another embodiment of the present invention.
제3도는 종래 중공 돌출조의 합성수지 나선관의 단면도.3 is a sectional view of a synthetic resin spiral tube of a conventional hollow protrusion.
본 고안은 합성수지제 나선관에 있어서, 나선을 이루는 중공형 돌출조안에 보강대를 형성되게 하여 내압성을 보다 증대시킴과 동시에 외적으로 찌그러짐이 없이 미려하게 유지되게 한 중공형 돌출조에 보강대를 형성한 합성수지 나선관에 관한 것이다.The present invention is made of a synthetic spiral helix in which a reinforcing rod is formed in a spiral protrusion made of a spiral protrusion in which a reinforcing rod is formed in a hollow protrusion protrusion forming a spiral, thereby increasing pressure resistance and maintaining a beautiful appearance without distortion. It's about the coffin.
종래의 합성수지 나선관에 있어서, 그 재질이 염화비닐등으로된 고강도 나선관은 외형의 변화는 일어나지 않으나 외부의 충격에 쉽게 깨지거나 부서지는 결점이 있었고, 그 재질이 폴리 에칠렌 등 연질로된 합성수지 나선관에 있어서는 나선으로 형성된 돌출조가 중공형으로 되어 있는 관계로 깊은 지중(地中)에 매설시나 관 연결시에 돌출조가 찌그러지는 등의 압에 대하여 응력이 약하거나 또는 관연결시에 틈새가 발생하기 쉬워서 하수도용이나, 배수용으로는 완전한 기능을 유지하지 못했던 경우가 있었고, 또한 그 관의 구경이 컴짐에 따라 중공형의 돌출조 역시 비례하여 커지므로 구경이 큰 관일수록 전기한 결점은 더욱 커졌던 결점이 있었다.In the conventional synthetic resin spiral tube, the high-strength spiral tube whose material is made of vinyl chloride or the like has no defect in appearance but is easily broken or broken by external impact, and its material is a synthetic resin spiral made of soft polyethylene or the like. In the pipe, the spirally formed projection is hollow, so that the stress is weak against pressure such as when the projection is crushed when buried in the deep ground or when the pipe is connected. In some cases, it was not easy to maintain its full function for sewerage or drainage. Also, as the diameter of the pipes increased, the hollow protrusions also increased proportionally. There was a flaw.
본 고안은 전기한 바와같은 중공 돌출조가 나선으로 형성된 연질의 합성수지 관에 있어서 그 결점을 제거코져 고안한 것으로서 본 고안의 요지를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is devised to remove the drawbacks in the soft synthetic resin tube formed in the spiral hollow hollow tub as described above as described in detail by the accompanying drawings the gist of the present invention.
내부가 중공부(1)로 된 나선형 돌출조(2)가 형성된 합성 수지관에 있어서, 중공부(1)의 내부에 세로 보강대(3)를 형성하되 나선형 돌출조(2)에 일체로 형성하거나 또는 세로 보강대(3)의 양측으로 가로 보강대(4)(4')를 형성하되, 역시 나선형돌출조(2) 및 세로 보강대(3)에 일체로 되게 형성한 것이다.In the synthetic resin tube in which the spiral protrusion (2) formed inside the hollow part (1), the longitudinal reinforcement (3) is formed inside the hollow part (1), but is integrally formed in the spiral protrusion (2) or Alternatively, horizontal reinforcing bars 4 and 4 'are formed on both sides of the vertical reinforcing bar 3, but are also formed to be integral with the spiral protrusion 2 and the vertical reinforcing bar 3.
이와같은 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention as follows.
종래의 이 종류의 나선관은 나선돌출조(2)의 내부에 중공부(1)만 형성되어 있으므로 지중매설시나 관 연결시에 외부의 압력으로 인하여 나선 돌출조(2)가 안으로 찌그러지게 되어 관의 보강적인 역활 기능이 떨어지게 되고 연결관으로 관 연결시는 그 기밀성이 떨어지게 되어 효과적인 나선관의 기능이 저하 되었던 것이나, 중공부(1) 내벽의 중앙에 일체로 형성된 세로 보강대(3)에 의하여 외부 압력에 대한 내부 용력을 높히므로서, 나선돌출조(2)가 변형됨이 없이 나선관의 기능을 향상 시킬 수 있는 것이고, 또한 가로 보강대(4)(4')를 세로 보강대(3) 및 나선돌출조(2)에 일체로 형성되게 하므로서, 수직 방향의 압력외에 측 방향 및 경사 방향의 압력에 대한 내부 용력을 높일 수 가 있어서, 통상의 중공형 돌출조의 합성수지 나선관의 잇점인 재료가 절감되고 관 자체가 가벼운 장점을 살리면서도 외부 압력 및 내부 압력에 대한 관 자체의 대응력이 보다 종래될 수 있는 효과가 있는 것이다.In the conventional spiral tube of this type, since only the hollow portion 1 is formed inside the spiral protrusion tank 2, the spiral protrusion 2 is crushed inward due to external pressure at the time of underground laying or pipe connection. Its reinforcing role is lowered and the airtightness is lowered when the pipe is connected to the connection pipe, so that the function of the effective spiral pipe is lowered, but the outer part is formed by the vertical reinforcement (3) integrally formed at the center of the inner wall of the hollow part (1). By increasing the internal capacity against pressure, it is possible to improve the function of the spiral tube without deforming the spiral projection tank (2), and also the horizontal reinforcement (4) (4 ') to the longitudinal reinforcement (3) and spiral By being formed integrally with the projection 2, the internal capacity to the lateral and inclined pressures in addition to the pressure in the vertical direction can be increased, thereby reducing the material that is an advantage of the synthetic resin spiral tube of the conventional hollow projection. While the tube itself takes advantage of the light, there is an effect that the tube itself can be more conventional than the external pressure and internal pressure.
