본 발명은 합성수지관의 일측면으로 확관부를 형성하여 연결이 편리하도록 하는 합성수지관에 관한 것으로The present invention relates to a synthetic resin pipe to form a convenient expansion pipe to one side of the synthetic resin pipe to facilitate the connection

더욱 상세하게는 가열한 후 확관부재를 이용하여 확관시키고 내경이나 외경 및 내경과 외경을 조사 가교하여 확관된 부분의 강도를 크게 향상시키는 보강된 확관부를 갖는 합성수지관 및 그 제조방법에 관한 것이다.More specifically, the present invention relates to a synthetic resin pipe having a reinforced pipe part which greatly expands the strength of the piped part by heating and expanding the pipe using an expansion member and irradiating and crosslinking the inner diameter or the outer diameter and the inner diameter and the outer diameter, and a method of manufacturing the same.

일반적으로 폴리에틸렌에 의해 성형되는 합성수지관은 상수도용으로 사용되는 상수도관과, 오수와 폐수용으로 사용되는 이중벽관, 가스를 공급하는데 사용되는 가스관이 사용된다.In general, the synthetic resin pipe formed by polyethylene is used as a water supply pipe used for tap water, a double wall pipe used for sewage and waste water, and a gas pipe used to supply gas.

상기 합성수지관은 그 특성사 일정한 간격(약 6미터)으로 생산되며, 합성수지관을 서로 연결시키기 위해서는 이음관이 이용된다.The synthetic resin pipe is produced at regular intervals (about 6 meters) of its yarn, and a joint pipe is used to connect the synthetic resin pipes to each other.

이음관은 이음관과 합성수지관의 접속방법에 따라서 융착식 이음관과 죔식 이음관 및 원터치형으로 조립하여 연결하는 편수관으로 나누어진다.The joint pipe is divided into fusion joint pipe, clamp joint pipe, and one-way pipe which is assembled and connected according to the connection method between the joint pipe and the synthetic resin pipe.

이중 죔식이음관을 제조하기 위해서는 합성수지관의 일측으로 별도로 성형시킨 이음관을 대고 상호 융착시키는 방법을 이용하게 되며, 이음관과 상수도관을 일 체형으로 성형시키기 위한 많은 결점을 해소시키기 위하여 특허등록 제0125616호가 제안되었다.In order to manufacture the double clamp joint pipe, a method of mutually fusion of the joint pipe formed separately to one side of the synthetic resin pipe is used, and a patent registration is made to solve many defects for forming the joint pipe and the water supply pipe into a single shape. 0125616 has been proposed.

특허등록 제0125616호는 합성수지관을 금형 내부에 삽입하고 원료를 공급하여 합성수지관과 이음관을 일체형으로 성형하는 방법이다.Patent Registration No. 0125616 is a method of molding a synthetic resin tube and a joint tube by inserting a synthetic resin tube into a mold and supplying raw materials.

그러나 이러한 방법을 통하여 이음관을 제조하는 경우라 해도 이음관의 내부에 연결되는 상수도관을 삽입한 후 이음관의 내부에 고무패킹을 삽입시킨 후 외부에서 고무패킹을 고정시키는 방법을 사용해야만 한다.However, even in the case of manufacturing a joint pipe through such a method, after inserting a water pipe connected to the inside of the joint pipe, the rubber packing must be inserted into the interior of the joint pipe, and a method of fixing the rubber packing from the outside should be used.

고무패킹을 고정시키는 구조는 국내 실용신안 공개번호 제20-2000-3316호(2000. 2. 150 공개)는 합성수지관의 이음관에 연결되는 상수도관을 삽입한 후 이음관에 고무패킹을 삽입하고 외부에서 배관 이음새를 조립시켜 이음관에 고정되면서 패킹을 강압하여 누수를 방지하는 것이다.The structure for fixing rubber packing is Korean Utility Model Publication No. 20-2000-3316 (published on Feb. 150), after inserting a water pipe connected to the joint pipe of synthetic resin pipe, insert rubber packing into the pipe. It is to prevent leakage by assembling pipe joints from the outside and fixing them to the joint pipes.

그러나 지하에 매설되는 합성수지관의 특성상 패킹을 강압하는 힘이 계속해서 제공되지 못하며, 패킹의 수명이 짧아서 쉽게 누수가 발생되므로 많은 수도물의 누수가 발생되는 결점이 있다.However, due to the nature of the synthetic resin pipes buried underground, the force to press down the packing is not continuously provided, because the leakage of water is easily generated due to the short life of the packing, there is a defect that a lot of tap water occurs.

또한 합성수지관의 일측면이 확관되거나 금형에서 별도로 성형한 후 합성수지관과 일체형으로 웰딩하여 연결된 편수관이 사용된다.In addition, one side pipe of the synthetic resin pipe is expanded or molded separately in the mold and welded integrally with the synthetic resin pipe is used.

상기 확관에 의한 편수관은 성형된 관을 가열하면서 강제로 확관시키는 방법을 사용하게 되므로 확관에 의하여 강도가 매우 취약한 구조로 변형되어 연결부분에서 누수와 체결력의 부족 등 많은 문제점이 발생하게 된다.Since the single-handed pipe by the expansion pipe uses a method of forcibly expanding the molded pipe while heating, the pipe is deformed into a structure that is very weak in strength due to the expansion pipe, causing many problems such as leakage and lack of fastening force in the connection part.

또한 금형에 의해 성형하여 웰딩으로 합성수지관과 연결하는 경우에는 제품 을 구분하여 생산해야 하므로 생산원가 및 금형의 소비가 크고, 서로 구분하여 생산된 제품을 서로 수지를 이용하여 연결시킨 후 사용하게 되므로 토압과 윤압 및 수압이 작용될 경우 연결부분에서 매우 취약한 단점이 발생하게 된다.In addition, when molding by mold and connecting with synthetic resin pipe by welding, it is necessary to separate and produce products, so production cost and consumption of mold are high, and the products produced separately are connected to each other using resin, so earth pressure When the overpressure and water pressure are applied, very weak points occur at the connection part.

본 발명은 이러한 종래의 결점을 해소시키기 위하여 안출된 것으로, 합성수지관의 확관부를 가열하면서 확관시킨 후 감마선 또는 전자빔의 조사에 의하여 확관에도 불구하고 강도가 크게 향상되도록 하는 것이다.The present invention has been made to solve the above-mentioned drawbacks, and after the expansion of the expansion tube of the synthetic resin tube while heating, the strength is greatly improved despite the expansion by irradiation of gamma rays or electron beams.

본 발명은 합성수지관의 확관부에 감마선 또는 전자빔의 조사에 의하여 확관한 후 내경이나 외경 또는 내경과 외경을 동시에 조사가교하여 강도를 향상시키도록 하는 것이다.The present invention is expanded to the expansion pipe portion of the synthetic resin tube by irradiation with gamma rays or electron beams to improve the strength by irradiating and cross-linking the inner diameter or the outer diameter or the inner diameter and the outer diameter at the same time.

Forming a synthetic resin tube by performing a reinforcing portion of the expansion portion to improve the strength by performing a conventional irradiation crosslinking to irradiate and crosslink the inner and outer diameters or gamma rays or electron beams in the state where the expansion portion is molded. will be.

본 발명의 합성수지관(100)은 수도관이나 가스관과 같이 일자형태로 압출하는 것을 사용하거나, 사각형 또는 사각형의 내부에 열십자형의 기둥이 세워져 있는 프로파일을 공급하여 나선형으로 감아가면서 그 사이에 수지를 공급하여 관을 성형하거나, 요철형태의 부재를 공급하면서 나선형으로 감아 요철형의 관을 제조하는 모든 수의 경우에 활용이 가능한 것이다.Synthetic resin pipe 100 of the present invention is used to extrude in a straight form, such as water pipes or gas pipes, or supply a resin while winding in a spiral while supplying a profile in which a crisscross column is built up inside a square or a square. It can be used in all the cases of forming a tube, or spirally winding while supplying a member of the concave-convex form to produce a concave-convex tube.

성형된 합성수지관(100)의 일측면으로 형성된 가열부(300)를 확관홈(610)이 형성된 성형틀(600)에 삽입하고 성형틀(600)에 전원을 공급하거나 액체 또는 기체와 같은 열원을 공급하여 가열되도록 한다.Insert the heating part 300 formed on one side of the molded synthetic resin tube 100 into the molding die 600 formed with the expansion groove 610 and supply power to the molding die 600 or a heat source such as liquid or gas. Supply to allow heating.

성형틀(600)에서 열원이 제공되면 가열부(300)가 가열되면서 응고(냉각)된 상태가 약간 부드러운 상태로 변형되면 일측에서 확관부재(200)가 도 1 과 도 3 에 도시한 바와 같이 내경(110)을 향하여 진행된다.When the heat source is provided in the mold 600, when the heating part 300 is heated and the solidified (cooled) state is deformed to a slightly soft state, the expansion member 200 at one side has an inner diameter as shown in FIGS. 1 and 3. Proceed toward 110.

확관부재(200)가 합성수지관(100)의 내경(110)을 향하여 진행되면서 선단면 에서부터 서서히 확관부재(200)의 형상을 따라 가열부(300)가 변형된다.As the expansion member 200 proceeds toward the inner diameter 110 of the synthetic resin tube 100, the heating part 300 is deformed along the shape of the expansion member 200 gradually from the front end surface.

도 4 와 같이 확관부재(200)가 완전히 진입하게 되면서 정지하게 될 때 합성수지관(100)의 내경(110)은 성형틀(600)의 확관홈(610)의 형상을 따라 성형상태가 유지되면서 확관부(400)가 성형된다.When the expansion member 200 is completely stopped as shown in Figure 4 when the inner diameter 110 of the synthetic resin tube 100 is expanded while maintaining the molding state along the shape of the expansion groove 610 of the molding die 600 The pipe 400 is molded.

합성수지관(100)의 성형상태가 유지되면서 성형틀(600)과 가열부(300)를 냉각시키면 변형된 상태가 그대로 유지되면서 냉각되므로 확관부(400)가 성형되는 것이다.When the molding mold 600 and the heating part 300 are cooled while the molding state of the synthetic resin tube 100 is maintained, the expansion part 400 is molded because the deformed state is maintained while being cooled.

확관부(400)가 성형된 후에는 합성수지관(100)을 좌측으로 분리하거나, 성형틀(600)을 이등분하여 벌린 후 합성수지관(100)을 분리한다.After the expansion pipe 400 is molded, the synthetic resin tube 100 is separated to the left, or the molding die 600 is divided into two and then separated to separate the synthetic resin tube 100.

도 2 와 도 5 에 도시한 바와 같이 합성수지관(100)의 일측으로 확관부(400)의 성형이 완료되면, 확관부(400)가 최초의 상태보다 확관되면서 외측으로 늘어난 상태가 되므로 다른 곳보다 얇아서 강도가 낮아진 상태가 된다.As shown in Figures 2 and 5 when the molding of the expansion portion 400 to one side of the synthetic resin tube 100 is completed, the expansion portion 400 is expanded to the outside while expanding than the first state, so than other places It becomes thin and becomes the state with low strength.

그러나 도 6 과 같이 확관부(400)의 내경(110)과 외경(120)에 감마선을 조사하거나 전자빔을 조사하여 조사 가교부(500)를 형성하게 되면 비록 얇아진 상태를 유지하지만 조사 가교에 의하여 확관부(400)의 강도를 향상시킬 수 있는 것이다.However, when the irradiation crosslinking portion 500 is formed by irradiating gamma rays or electron beams to the inner diameter 110 and the outer diameter 120 of the expansion pipe 400 as shown in FIG. The strength of the pipe 400 can be improved.

상기 감마선이나 전자빔을 조사하는 경우에는 도 6 과 같이 내경(110)과 외경(120)을 동시에 조사하여 강도를 향상시킬 수 있으나, 도 7 에 도시한 바와 같이 감마선이나 전자빔을 외경(120)에만 조사하여 외경(120)의 강도를 향상시킬 수 있으며, 도 8 에 도시한 바와 같이 감마선이나 전자빔을 내경(110)에만 조사하여 내경(110)의 강도를 향상시킬 수 있는 것이다.In the case of irradiating the gamma ray or the electron beam, the intensity can be improved by irradiating the inner diameter 110 and the outer diameter 120 at the same time as shown in FIG. 6, but as shown in FIG. 7, the gamma ray or the electron beam is irradiated only on the outer diameter 120. The strength of the outer diameter 120 can be improved, and as shown in FIG. 8, the intensity of the inner diameter 110 can be improved by irradiating a gamma ray or an electron beam only to the inner diameter 110.

또한 도 6 내지 도 8 과 같이 내경(110)과 외경(120)에 감마선이나 전자빔을 각각 조사하거나 어느 한곳만을 조사할 수 있으나 도 9 에 도시한 바와 같이 내경(110)과 외경(120)에 조사 가교된 수지를 공급하여 씌우(도포)는 방법을 통하여 강도를 향상시킬 수 있는 것이다.Also, as shown in FIGS. 6 to 8, the inner diameter 110 and the outer diameter 120 may be irradiated with a gamma ray or an electron beam, respectively, or only one of them may be irradiated to the inner diameter 110 and the outer diameter 120. It is possible to improve the strength through the method of supplying and applying crosslinked resin.

이러한 본 발명의 바람직한 실시예를 첨부시킨 도면에 따라서 상세하게 설명하기로 한다.According to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

확관홈(610)이 형성된 성형틀(600)에 합성수지관(100)의 일측면을 삽입한다.One side of the synthetic resin tube 100 is inserted into the molding die 600 in which the expansion groove 610 is formed.

(3) 가열과정(3) heating process
