배관시설을 위해 사용되는 관(파이프)의 경우 길이 확보를 위하여 관을 연결하여 사용하고 있다.In the case of pipes (pipes) used for plumbing facilities, pipes are connected to secure the length.

상기와 같이 관을 연결하는 수단으로, 관에 파이프 머신을 이용하여 나사산을 형성하여, 관에 형성한 나사산과 결합하는 나사산을 형성한 연결구를 이용하여 관을 연결하는 방법이다.As a means of connecting a pipe as described above, a pipe is formed in the pipe by using a pipe machine, and the pipe is connected by using a threaded connector that is coupled to the thread formed in the pipe.

그러나 상기와 같은 관의 연결은, 현장에서 관에 나사산을 형성하는 불편함과, 나사산에 의해서 절삭된 관의 두께가 얇아져 나사산 부분이 쉽게 부식되는 문제점이 있으며, 관과 연결구를 결합하는 과정에서 기밀성을 위하여 관의 나사산에 테이핑 작업을 하므로, 나사산에 감기는 테이프의 폭과 두께에 따라 연결구에 결합하는 나사산의 깊이가 달라, 기밀성이 유지되지 않으며 결합하는 관의 길이가 일정하지 않은 문제점이 있었다. However, the connection of the pipe as described above, the inconvenience of forming a thread on the pipe in the field, and the thickness of the pipe cut by the thread is a problem that the thread portion is easily corroded, the airtightness in the process of coupling the pipe and the connector Since the tape work on the thread of the pipe for the purpose, the depth of the thread is coupled to the connector according to the width and thickness of the tape wound on the thread, there is a problem that the airtightness is not maintained and the length of the joining pipe is not constant.

본 발명은 상기 문제점을 해결하기 위해 안출된 것으로, 그 목적은 외주연에 커플러의 내면에 형성된 암나사산에 결합되는 숫나사가 형성된 연결부재를 이용하여 관과 관을 연결함으로써 현장에서 관에 나사산을 형성하는 작업을 하지 않고도 관과 관을 용이하고 신속하게 연결할 수 있으며, 길이방향으로 절개된 연결부재를 사용함으로써 연결부재의 직경이 변화될 수 있도록 하여 관의 직경에 변화하더라도 연결부재를 호환하여 사용할 수 있게 한 연결부재를 이용한 관 연결공법를 제공하는 것이다.The present invention has been made to solve the above problems, the object is to form a screw thread on the pipe in the field by connecting the pipe and the pipe using a male threaded coupling member formed on the inner thread of the coupler formed on the inner surface of the coupler It is possible to connect pipes and pipes easily and quickly without any work to be done, and it is possible to use the connecting members interchangeably even if the diameter of the pipes is changed by changing the diameter of the connecting members by using the connecting members cut in the longitudinal direction. It is to provide a pipe connection method using a connecting member.

Referring to the drawings, the pipe connection method according to the present invention is characterized in connecting the pipe (1) and the pipe (1) using the connection member 10 and the coupler (20).
Here, the connecting member 10 is a pipe shape with a male thread 12 formed on an outer surface thereof, and the male thread is a screw thread coupled with a female thread formed on an inner surface of a coupler to be described later. Preferably, the connecting member has a diameter of the connecting member adjusted. The incision 11 cut in the longitudinal direction is formed.
In addition, the coupler 20 has a stepped portion 22 formed inside the center, and both ends of the stepped internal thread 21 are formed to engage with the male thread 12 of the connection member.

상기와 같은 연결부재와 커플러를 이용하여 관과 관을 서로 연결하는 공법을 이하에서 설명한다.A method of connecting the pipe and the pipe to each other by using the connection member and the coupler as described above will be described below.

본 발명에 따르면 먼저 외면에 숫나사산(12)이 형성된 파이프 형상의 연결부재(10)의 내부에 관(1)을 삽입한 다음 상기 관(1)과 연결부재(10)를 용접으로 고정한다. 여기서, 용접방식으로는 다양한 공법이 적용될 수 있지만, 서포트 용접이 바람직하다.According to the present invention, first, the tube 1 is inserted into the inside of the pipe-shaped connecting member 10 in which the male thread 12 is formed on the outer surface, and then the pipe 1 and the connecting member 10 are fixed by welding. Here, various welding methods may be applied as the welding method, but support welding is preferable.


상기와 같이 연결부재와 관을 용접으로 고정한 다음에는 전술한 중앙 내부에는 단턱(22)이 형성되고 상기 단턱 양측 내면에는 상기 연결부재의 숫나사산(12)과 치합되는 암나사산(21)이 형성된 커플러(20)를 마련하고, 상기 커플러(20)의 단턱(22) 양측으로 기밀성을 유지하는 패킹(30)을 삽입한다.
After fixing the connection member and the pipe by welding as described above, the stepped portion 22 is formed in the above-described center, and the coupler having female threads 21 engaged with the male thread 12 of the connection member formed on both inner surfaces of the stepped portion. (20) is provided, and the packing (30) for maintaining airtightness is inserted into both sides of the step (22) of the coupler (20).

상기와 같이 패킹(30)이 삽입되면, 상기 관(1)이 용접으로 고정된 연결부재(10)를 커플러(20) 양측 내부에 각각 삽입한 다음 연결부재(10) 외면의 숫나사산(12)과 커플러 내면의 암나사산(21)을 서로 결합하여 연결부재(10)와 커플러(20)를 결합함으로써 본 발명에 따른 관 연결공법이 완료되게 된다.When the packing 30 is inserted as described above, the tube 1 is inserted into the coupling member 10 fixed by welding, respectively, inside the coupler 20, and then the male thread 12 on the outer surface of the coupling member 10. By coupling the female thread 21 of the inner surface of the coupler and the coupling member 10 and the coupler 20 by combining with each other, the pipe connection method according to the present invention is completed.

상기와 같이 완료된 본 발명의 관 연결공법에 따르면, 미리 제작된 커플러와 연결부재를 통해 관을 연결하기 때문에 관 연결작업이 용이하다는 잇점이 있다. 또한, 종래와 같이 현장에서 관에 나사산을 형성하지 않고도 커플러와 연결부재를 이용하여 관과 관을 서로 연결할 수 있기 때문에 파이프 머신을 통한 나사산 작업을 하지 않아 관 연결작업을 신속하게 할 수 있다는 잇점이 있다.
나아가, 본 발명에서 연결부재(10)에 형성된 절개부(11)에 의해 연결부재(10)의 지름이 조절될 수 있기 때문에 연결부재(10)에 결합하는 관(1)의 직경에 미세한 차이가 있더라도 연결부재의 직경이 커지면서 관이 연결부재에 결합되므로, 관의 직경에 차이가 있다 하더라도 연결부재를 호환하여 사용할 수 있다는 잇점이있다.According to the pipe connection method of the present invention completed as described above, there is an advantage that the pipe connection operation is easy because the pipe is connected through the coupler and the connection member prepared in advance. In addition, since the pipe and the pipe can be connected to each other using a coupler and a connection member without forming a thread in the pipe as in the conventional art, the pipe connection work can be quickly performed without the thread work through the pipe machine. have.
Furthermore, since the diameter of the connection member 10 may be adjusted by the cutout 11 formed in the connection member 10 in the present invention, a slight difference in the diameter of the pipe 1 coupled to the connection member 10 may be obtained. Even though the diameter of the connecting member is increased, the pipe is coupled to the connecting member, so even if there is a difference in the diameter of the pipe, the connecting member can be used interchangeably.
