Abstract

본 발명은 일정길이로 절단된 상수도관의 일측 외경에 홈을 형성하고, 그 홈이 형성된 관의 일단부를 가열한 다음, 가열된 관의 일단부를 내, 외금형에 삽입하되 관의 내경에 내금형의 입단을 끼우고 외금형에 형성된 개구부를 통하여 관의 일단부가 외금형내에 돌출되도록 한 후, 내, 외금형 사이의 공간부에 합성수지를 사출하여 관의 일단부 외경에 이음관을 일체로 접합, 성형하는 상수도용 합성수지관의 이음관 접합방법에 관한 것으로서, 금형내에 이음관 소재인 합성수지 용융물을 사출하기 전에 이음관이 접속되는 상수도관의 외경에 다수의 홈을 형성하여 그 홈에 합성수지 용융물이 출입되도록 함과 아울러 이음관이 접합되는 상수도관의 외경부를 용융직전의 상태로 될 때까지 가열한 후 그 외경부에 합성수지를 사출하기 때문에 이음관이 상수도관의 일단부에 긴밀하게 접합되게 되는 특징이 있다.The present invention forms a groove on one side outer diameter of the water pipe cut to a certain length, and heating one end of the tube formed with the groove, and then inserted one end of the heated tube into the inner mold, the inner mold of the tube Insert one end of the tube and let one end of the tube protrude into the outer mold through the opening formed in the outer mold, and then, by injecting a synthetic resin into the space between the inner and outer molds, the joint pipe is integrally joined to the outer diameter of one end of the tube. The present invention relates to a joint pipe joining method of a synthetic resin pipe for molding water, wherein a plurality of grooves are formed in the outer diameter of a water pipe to which the joint pipe is connected before the synthetic resin melt, which is a joint pipe material, is formed in the mold, and the synthetic resin melt enters and exits the groove. In addition, the outer pipe of the water pipe to which the pipe is joined is heated until it is ready to be melted, and then the synthetic pipe is injected into the outer pipe. It is characterized by being closely joined to one end of the water pipe.
