본 발명은 상수도용 신축편수관 융착연결구에 관한 것으로서, 보다 상세하게는 전기에 의한 열선을 이용하여 열선 주변부에 열선에 의해 용융접합되는 합성수지 재질의 용융부를 미리 형성하여 용용시 변형이나 내부로의 찌그러짐을 미리 방지하고, 보강지지바에 의해 편수관을 연결구와 밀착고정시킴으로써 외부충격에 의한 변형을 방지하면서 누수를 차단할 수 있는 상수도용 신축편수관 융착연결구에 관한 것이다.The present invention relates to a fusion splicing fusion splicing connector for waterworks, more specifically, by forming a molten portion of a synthetic resin material melt-bonded by a hot wire in the periphery of the hot wire using an electric heating wire to deform or distort the inside during melting The present invention relates to a watertight and flexible watertight pipe fusion splicing connector that can prevent leakage while preventing deformation by external shock by tightly fixing the watertight pipe to the connector by a reinforcing support bar.

일반적으로, 배관재는 철 금속 재질의 부식 단점을 보완한 도금형관과, 비철금속재관 및 콘크리트관으로 크게 구분되어 사용되고 있는데, 이러한 철금속 도금형관이나 비철금속 배관재는 제조원가가 고가인데다 설치 후 쉽게 부식되는 등 설비 제작시 비경제적이고 사후관리에는 비효율적이었다.In general, piping materials are largely divided into plated pipes and non-ferrous metal pipes and concrete pipes that compensate for the corrosion disadvantages of ferrous metals, and such ferrous metal-coated pipes and non-ferrous metal pipes are expensive to manufacture and are easily corroded after installation. It was inefficient for manufacturing and inefficient for follow-up.

최근에는 석유화학공업이 발달되어 개발된 플라스틱 관을 사용하여 각 가정과 공장 등의 식수배관인 상수도뿐만 아니라, 오·폐수 및 우수 배관인 하수도와 독극성이 강한 유체 등의 공업용 배관재로 널리 사용되고 있으며, 이러한 플라스틱 배관재의 소재로는 폴리에틸렌(polyethylene/PE), 폴리염화비닐(polyvinyl chloride/PVC), 또는 폴리프로필렌(poly propylene/PP) 등이 많이 사용되고 있다.Recently, plastic pipes developed and developed by the petrochemical industry are widely used as industrial piping materials such as sewage and sewage, which are excellent pipes, as well as tap water, which is drinking water piping for homes and factories. Polyethylene (PE), polyvinyl chloride (PVC), polypropylene (poly propylene / PP) and the like are used as a material of the plastic piping material.

위와 같은 플라스틱 배관재는 일정 길이로 양산되어 현장에서 연결하여 사용 되는데, 플라스틱 배관재를 연결하는 방법으로는 전기를 사용하여 융착하는 방법(electric welding type)과 열수축시트를 사용하는 방법(socket welding type), 및 배관들의 단부에 플랜지를 융착하여 연결하는 방법(flange welding type) 등이 사용되고 있다.The above plastic piping materials are mass-produced to a certain length and used in the field, and the plastic piping materials are connected by electric welding (electric welding type) and heat shrink sheet (socket welding type), And a method of welding a flange to the ends of pipes (flange welding type).

상기 체결지지구(20,20a)는 좌우 한 쌍으로, 일측 편수관(30)이나 타측 편수관(30a)의 외주연에 삽입고정되는 고정링(21)이 형성되되, 고정링(21)의 사방에 조임장볼트(22)가 내측으로 삽입고정되고, 그 내측에는 조임공(23)이 형성되며, 일단이 조임공(23)에 위치되어 조임장볼트(22)에 의해 체결고정되되, 조임장볼트(22)의 조임에 따라 조임공(23) 내측으로 이동되고 타측이 상기 융착연결구(10) 삽입장홈(13)에 삽입되어 용융부(11a)에 용착되는 보강지지바(24)가 형성된다. The fastening support (20, 20a) is a pair of left and right, the fixing ring 21 is inserted into the outer periphery of one side of the knitting tube 30 or the other side of the knitting tube 30a is formed, the four sides of the fixing ring 21 Tightening bolt 22 is inserted into the inside fixed, the tightening hole 23 is formed therein, one end is located in the tightening hole 23 is fastened and fastened by the tightening bolt 22, tightening bolt As the tightening of the (22) is moved into the tightening hole (23) and the other side is inserted into the fusion connector (10) insertion long groove 13 is formed a reinforcement support bar 24 which is welded to the melted portion (11a).

이와 같은 본 발명은, 일타측 편수관(30,30a)의 선단부에 고정링(21)을 끼운 다음, 일타측 편수관(30,30a)의 선단을 융착연결구(10)의 좌우측 내주연에 삽입시키고, 보강지지바(24)의 타측을 삽입장홈(13) 내측에 삽입시킨다.In the present invention, the fixing ring 21 is inserted into the front end of the other side knitting pipe 30, 30a, and the front end of the other side knitting pipe 30, 30a is inserted into the left and right inner circumference of the fusion splicer 10, The other side of the reinforcing support bar 24 is inserted into the insertion groove 13.

그 다음, 체결지지구(20,20a)의 조임장볼트(22)를 조여서 보강지지바(24)를 조임공(23) 내측으로 밀착시키고, 또한 타측을 삽입장홈(13) 내에서 용융부(11a)와 밀착시킨다.Then, tighten the tightening bolts 22 of the fastening supports 20 and 20a to bring the reinforcing support bar 24 into close contact with the tightening hole 23, and the other side of the fastening portion 20 in the insertion length groove 13. In close contact with 11a).

이 상태에서 융착연결구(10) 외주연 중심의 접속부(14)에 전원을 일정시간만 공급하면, 배선(15)을 통해서 내부의 열선(12)에 전기가 공급되어 전기에너지는 열에너지로 바뀌어서 합성수지 재질인 용융부(11,11a)를 녹여서 일타측 편수관(30,30a)의 외주연과 융착연결구(10)의 내주연을 용착고정되고, 체결지지구(20)의 보강지지바(24)는 융착연결구(10)의 삽입장홈(13) 용융부(11a)와 용착고정된다. 이때, 평수관(30,30a)의 외주연과 접하는 용융부(11)는 열선(12)에 의해 원활하게 용융되나, 보강지지바(24)와 접하는 용융부(11a)는 열선(12)과 이격되어 일부만이 용융될 수 있는 것으로 이는 보강지지바(24)를 고정지지할 정도이면 족하고, 이미 보강지지바(24) 조인장볼트(22)에 의해서 체결지지구(20,20a)에 고정되는바, 보강지지바(24)가 용융부(11a)에 의해 용착되지 않더라도 이미 편수관(30,30a)의 외주연은 융착연결구(10)과 용착고정된 상태이므로 아무런 영향을 미치지 않게 된다.In this state, if power is supplied only to the connection portion 14 of the outer circumferential center of the fusion splicer 10 for a predetermined time, electricity is supplied to the internal heating wire 12 through the wiring 15, and the electrical energy is converted into thermal energy, thereby making it a synthetic resin material. By melting the phosphorus melting portion (11, 11a) is welded and fixed to the outer periphery of the other side of the knitting pipe (30, 30a) and the inner periphery of the fusion splicing 10, the reinforcing support bar 24 of the fastening support (20) is fused It is welded and fixed to the insertion part groove 13 of the connector 10, the melted portion (11a). At this time, the melted portion 11 in contact with the outer periphery of the smooth water pipes 30 and 30a is smoothly melted by the hot wire 12, but the melted portion 11a in contact with the reinforcing support bar 24 is connected to the hot wire 12. Only a part of the spaced apart can be melted, which is enough to support the reinforcement support bar 24, and is already fixed to the fastening supports 20 and 20a by the reinforcement support bar 24 and the joining bolt 22. Bar, even if the reinforcing support bar 24 is not welded by the melting part 11a, the outer periphery of the knitting pipes 30 and 30a is already welded and fixed to the fusion splicing 10 so that there is no effect.

이렇게 융착연결구(10)에 의해서 용착고정된 일타측 편수관(30,30a)은 외부충격에 의해 변형되지 않고, 용융시 변형되거나 찌그러지지 않게 된다.The other side knitting pipes 30 and 30a welded and fixed by the fusion connector 10 are not deformed by external impact and are not deformed or crushed when melted.

또한, 단지 적정시간의 전원연결만으로 일타측 편수관(30,30a)을 보다 완강하게 접합고정시키게 된다.In addition, only the connection of the power of the appropriate time will be more firmly bonded to the other side knitting pipes (30, 30a).

이와 같이, 본 발명은 전기에 의한 열선을 이용하여 열선 주변부에 열선에 의해 용융접합되는 합성수지 재질의 용융부를 미리 형성하여 용용시 변형이나 내부로의 찌그러짐을 미리 방지하고, 보강지지바에 의해 편수관을 연결구와 밀착고정시킴으로써 외부충격에 의한 변형을 방지하면서 누수를 차단할 수 있는 효과가 있다.As described above, the present invention forms a molten portion of a synthetic resin material which is melt-bonded to the periphery of the hot wire by means of a hot wire by using an electric hot wire to prevent deformation and crushing in advance, and to connect the knitting pipe by a reinforcing support bar. By fixing in close contact with and there is an effect that can block the leak while preventing deformation due to external impact.
