Description

관 연결구{Seamed pipe for pipe}Sealed pipe for pipe

본 발명은 관 연결구에 관한 것으로, 특히 동이나 주철의 금속관을 연결할 때 연결부위의 단면과 내면 및 외면의 3면이 긴밀하게 접합되도록 하여 완전한 연결이 가능하도록 한 관 연결구에 관한 것이다.The present invention relates to a pipe connector, and more particularly to a pipe connector that allows a complete connection by connecting the end surface of the connection portion and the three surfaces of the inner and outer surfaces when connecting the metal tube of copper or cast iron.

일반적으로 하수관 등에 많이 사용되는 동관, 주철관 또는 합성수지관은 제작과 운반에 따른 제약으로 인해 단위 길이로 생산할 수밖에 없고, 실제로 지하에 매몰되는 공급관과 배출관 및 하수관은 그 전체 길이가 매우 길어야 되는 경우도 있으므로 여러 개의 동관, 주철관 또는 합성수지관을 현장에서 연결하면서 설치하여야 하였음은 이미 주지된 사실이다.In general, copper pipes, cast iron pipes, or synthetic resin pipes, which are frequently used in sewage pipes, have to be produced in unit lengths due to constraints in manufacturing and transportation, and in fact, supply pipes, discharge pipes, and sewage pipes buried underground may have to be very long. It is well known that several copper pipes, cast iron pipes or synthetic pipes had to be installed in the field.

그리고 종래에는 현장에서 합성수지관을 연결하기 위하여 도1에 도시된 바와 같이, 연결코자 하는 양 합성수지관의 내경과 외경에서 지지하는 내부 지지링(2)과 외부 지지링(3)의 사이에 얇은 열선판(4)을 배치한 융착링(1)에 연결하고자 하는 두 합성수지관을 삽입한 후 단자선(5)을 통하여 전기를 공급하면서 연결하도록 하였다.And conventionally, as shown in Figure 1 to connect the synthetic resin pipe in the field, a thin hot wire between the inner support ring (2) and the outer support ring (3) for supporting at the inner and outer diameter of both synthetic resin tubes to be connected After inserting the two synthetic resin pipes to be connected to the fusion ring (1) in which the plate (4) is arranged to connect while supplying electricity through the terminal line (5).

즉, 종래의 합성수지관 연결 시공은 융착링(1)을 연결코자 하는 양 합성수지관의 중간에 위치시키고, 유압 연결장치나 수동 연결장치를 이용하여 합성수지관을 밀착시킨 후, 열선판(4)의 단자선(5)에 전기를 가하면 열선판(4)이 발열되면서 양측 합성수지관의 단부를 용융시키게 되고, 상기 합성수지관의 용융물은 열선판(4)의 공극을 스며들어가 서로 혼합된 후, 전기를 차단시키면 용융된 용융물이 시간이 지남에 따라 서서히 경화되면서 양 합성수지관은 하나의 몸체로 견고히 연결되도록 하였다.That is, the conventional synthetic resin pipe connection construction is located in the middle of both synthetic resin pipes to connect the fusion ring (1), and after the synthetic resin pipes by using a hydraulic connection device or a manual connection device, and then of the hot wire plate (4) When the electric wire is applied to the terminal line 5, the heating wire 4 is heated to melt the ends of the synthetic resin pipes on both sides, and the melt of the synthetic resin pipe penetrates the pores of the heating wire 4 and is mixed with each other. When blocked, the molten melt slowly hardened over time, allowing both synthetic tubes to be firmly connected to a single body.

그러나 상기한 바와 같은 종래의 합성수지관 연결시공은 융착링(1)을 이용하여 합성수지관을 연결할 때 현장에서 융착링(1)의 양단에 합성수지관을 끼워서 연결시공을 하기 때문에 융착링(1)의 구조상 작업시간이 오랜 시간이 소요될 뿐만 아니라 연결시공이 정밀하게 이루어지지 못하는 문제점이 있었다.However, in the conventional synthetic resin pipe connecting construction as described above, when the synthetic resin pipe is connected using the fusion ring (1), the synthetic resin pipe is connected to both ends of the fusion ring (1) in the field so that the construction of the fusion ring (1) There was a problem in that it takes not only a long time, but also the connection construction is not precise.

상기 융착링(1)의 양측에서 부착되는 두 합성수지관이 단면만 접하는 상태에서 결합되므로 접합면적이 적음으로 인해 장시간 매입된 상태에서 사용하여야 하며 큰 압력이 작용하는 상태에서 접합부위가 손상을 입게 되는 단점이 있었다.Since the two synthetic resin pipes attached at both sides of the fusion ring 1 are in contact with only the end face, they must be used for a long time due to the small joint area, and the joint part is damaged in the state where a large pressure is applied. There was a downside.

그리고 종래의 동관이나 주철관을 연결하기 위하여 사이에 결합하는 연결구도 양측에서 연결하고자 하는 동관이나 주철관과 단면만 접하는 상태에서 결합하여야 하므로 안정된 작업이 이루어지지 않게 되는 등의 원인이 있었다.And in order to connect the conventional copper pipe or cast iron pipe, there is a cause such that the stable work is not made because the coupling between the connection between the copper tube or cast iron pipe to be connected only in contact with both sides in the state.

더구나 상기의 동관, 주철관 또는 합성수지관을 융착링이나 연결구로 접합하는 부위가 지면이나 도로 등의 요인으로 인해 경사각을 이루거나 휘어지도록 설치되는 경우에는 접합면의 손상이 더욱 빠르게 진행될 수 있어 단면에 의한 단순한 접합방법을 보강하기 위한 기술이 필요한 실정이었다.In addition, when the part connecting the copper pipe, cast iron pipe, or synthetic resin pipe with a fusion ring or connector is installed to form an inclination angle or bend due to factors such as the ground or road, damage of the joint surface may proceed more quickly. There was a need for a technique for reinforcing a simple joining method.

이에, 본 발명은 상기한 바와 같은 종래의 문제점을 해소하기 위해 안출된 것으로써, 동이나 주철의 금속관을 연결할 때 연결부위의 단면과 내면 및 외면의 3면이 긴밀하게 접합되도록 하여 완전한 연결이 가능하도록 한 관 연결구를 제공하는데 그 목적이 있다.Therefore, the present invention has been devised to solve the conventional problems as described above, when connecting the metal tube of copper or cast iron, the end surface of the connection portion and the three surfaces of the inner surface and the outer surface can be closely joined so that complete connection is possible. The purpose is to provide a pipe connector for the purpose.

상기한 목적을 달성하기 위한 본 발명에 따른 관 연결구는 통상의 동관이나 주철관의 연결에 있어서,Pipe connector according to the present invention for achieving the above object in the connection of a common copper pipe or cast iron pipe,

동이나 주철로 성형하는 연결구의 양측 결합단부에 내면과 외면 및 단면이 동시에 접하는 결합홈이 일체인 "I"형으로 형성하여 상기의 "I"형 결합홈에 연결하고자 하는 관의 단면과 내면 및 외면이 동시에 접하면서 긴밀한 접합이 이루어지도록 함으로써 현장에서 동이나 주철의 금속관을 연결할 때 용이하고 정확하게 연결시킬 수 있을 뿐만 아니라 연결에 따른 작업시간을 단축시키도록 함을 특징으로 한다.The cross section and the inner surface of the pipe to be connected to the "I" type coupling groove formed by forming an "I" shape in which the coupling grooves in which the inner surface and the outer surface and the cross section are in contact at both sides of the coupling end formed of copper or cast iron are integral. As the outer surface is in contact with each other at the same time, a close connection is made, which enables easy and accurate connection when connecting metal pipes of copper or cast iron in the field, as well as shortening working time due to the connection.
