Description
본 발명은 피복형 파형강관의 이음장치에 관한 것으로, 보다 상세하게는 상호 연결하고자 하는 피복형 파형강관의 연결 부분의 구조적 강도, 내식성, 수밀성을 보다 향상시킴으로써, 피복형 파형강관의 연결부분의 파손, 누수, 및 누출을 방지하기 위한 피복형 파형강관의 이음장치 및 그 이음 방법에 관한 것이다.The present invention relates to a joint of a corrugated corrugated steel pipe, and more particularly, to improve the structural strength, corrosion resistance, and watertightness of the connection portion of the corrugated corrugated steel pipe to be interconnected, thereby to break the connection portion of the corrugated corrugated steel pipe The present invention relates to a joint of a corrugated corrugated steel pipe for preventing leakage, leakage, and leakage, and a method of jointing the same.
일반적으로, 금속재질로 이루어진 강관의 관면 상에 나선형 또는 비나선형의 주름을 부여한 파형강관이 널리 이용되는 추세이며, 이러한 파형강관은 구조적인 측면에서 매우 강한 특징이 있다.In general, corrugated steel pipes are provided in a spiral or non-helical corrugation on the tube surface of the steel pipe made of metal material, and these corrugated steel pipes have a very strong feature in terms of structure.
하지만, 이러한 파형강관은 내식성이 약하기 때문에, 최근에는 파형강관의 내, 외주면 상에 폴리에틸렌, 고밀도 폴리에틸렌, 폴리프로필렌 등과 같은 합성수지 재질을 피복함으로써, 내식성을 보강한 피복형 파형강관이 출시되고 있는 추세이다.However, since such corrugated steel pipes have poor corrosion resistance, recently coated corrugated steel pipes having reinforced corrosion resistance have been released by coating synthetic resin materials such as polyethylene, high density polyethylene, and polypropylene on the inner and outer circumferential surfaces of corrugated steel pipes. .
이러한 피복형 파형강관은 내식성 및 구조적 강도가 우수하여 주로 배수관, 오염도가 심한 생활 하수관, 공장 배수관 등에 이용되며, 이러한 피복형 파형강관이 현장에 시공될 때는, 다수의 파형강관이 서로 연결되어 시공된다.These corrugated corrugated steel pipes have excellent corrosion resistance and structural strength and are mainly used for drainage pipes, highly polluted living sewer pipes and factory drainage pipes. When these corrugated corrugated steel pipes are installed on site, a plurality of corrugated steel pipes are connected to each other. .
이러한 피복형 파형강관의 종래의 이음구조는 서로 연결되는 각 파형강관(101)의 단부가 일치된 상태에서 각 연결부 외측에 일정 넓이를 갖는 고무 패킹(102)이 감겨져 고정되고, 이러한 고무패킹(102)의 외측면에 금속재질의 커플링 밴드(103)가 체결되며, 이러한 커플링 밴드(103)의 양단에 형성된 플랜지(103a)가 볼트(104) 및 너트(105)에 의해 체결됨으로써, 파형강관(101)이 상호 연결되는 구조로 이루어졌다.In the conventional joint structure of such a corrugated corrugated steel pipe, a rubber packing 102 having a predetermined width is wound around and fixed to the outside of each connection part in a state where the ends of the corrugated steel pipes 101 connected to each other are matched. The coupling band 103 of the metal material is fastened to the outer side of the), and the flange 103a formed at both ends of the coupling band 103 is fastened by the bolt 104 and the nut 105 to form a corrugated steel pipe. 101 is made of a structure that is interconnected.
그러나, 이러한 종래의 이음구조는 시간이 지남이 따라 고무 패킹(102)이 변형되거나, 오폐수에 의해 쉽게 부식되고, 이로 인해 누수의 가능성이 현저하게 높아 토양 오염을 초래할 수 있는 문제점이 있었다.However, this conventional joint structure has a problem that the rubber packing 102 is deformed over time, or easily corroded by waste water, thereby causing a high possibility of water leakage, resulting in soil contamination.
또한, 지반의 상승 또는 침하에 의해 파형강관의 이음부에 전단력이 발생할경우에는, 구조적 강도측면에서 매우 취약한 단점이 있었다.In addition, when the shear force is generated in the joint portion of the corrugated steel pipe due to the rise or settlement of the ground, there was a weak point in terms of structural strength.
또한, 커플링 밴드는 오, 폐수 등에 의해 쉽게 부식될 수 있고, 볼트 및 너트의 조임이 느슨해져 파형강관의 이음부의 결합이 끊어질 수 있는 문제점이 있었다.In addition, the coupling band can be easily corroded by waste, wastewater, etc., there is a problem that the coupling of the joint of the corrugated steel pipe can be broken by loosening the tightening of the bolt and nut.
따라서, 본 발명은 상기와 같은 점을 감안하여 안출한 것으로, 파형강관의 이음부 상의 밀봉성, 내식성, 및 구조적 강도를 향상시켜 파형강관의 이음부 상에서 발생할 수 있는 파손 및 누수 등을 방지하기 위한 피복형 파형강관의 이음장치 및 이음방법을 제공하는 데 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and improves the sealing property, corrosion resistance, and structural strength on the joint of the corrugated steel pipe to prevent breakage and leakage that may occur on the joint of the corrugated steel pipe. It is an object of the present invention to provide a jointing device and a jointing method for the coated corrugated steel pipe.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명의 일 실시예에 따른 피복형 파형강관의 이음장치를 도시한 도면이다.2 is a view showing the joint of the corrugated corrugated steel pipe according to an embodiment of the present invention.
도시된 바와 같이, 본 발명의 피복형 파형강관의 이음장치는 서로 연결되어지는 피복형 파형강관(1, 2)의 상호 연결되는 부분의 외주면 상에 장착되는 가이드편(3)과, 이러한 가이드편(3) 상으로 용융상태의 열가소성 수지(4)를 주입하는 주입기(5)와, 가이드편(3) 및 피복형 파형강관(1, 2)의 연결되는 부분 사이에 코일 형태로 감겨진 전열선(6)으로 이루어진다.As shown, the joint of corrugated corrugated steel pipe of the present invention includes a guide piece 3 mounted on an outer circumferential surface of an interconnected portion of the corrugated corrugated steel pipes 1 and 2 to be connected to each other, and such a guide piece. (3) a heating wire wound in the form of a coil between the injector 5 for injecting the molten thermoplastic resin 4 onto the connecting portion and the connecting portion of the guide piece 3 and the coated corrugated steel pipes 1 and 2 ( 6)
가이드편(3)은 그 전, 후측에 가이드턱(3a)이 형성되고, 이러한 가이드턱(3a)에 의해 그 내부에는 소정 폭의 가이드홈(3b)이 형성되며, 그 일측에 소정의 주입구(3b)가 형성된 링 형상체이다. 이러한 가이드편(3)은 피복형 파형강관(1, 2)의 상호 연결되는 부분의 외주면 상에 장착된다. 이러한 가이드편(3)은 피복형 파형강관(1, 2)을 견고히 결합시키기 용이한 소정 면적을 구비한다.The guide piece 3 is formed with a guide jaw 3a at the front and rear sides thereof, and a guide groove 3b having a predetermined width is formed therein by the guide jaw 3a, and at one side thereof, a predetermined injection hole ( 3b) is a ring-shaped body formed. This guide piece 3 is mounted on the outer circumferential surface of the interconnected portions of the coated corrugated steel pipes 1 and 2. This guide piece 3 has a predetermined area which is easy to firmly couple the corrugated corrugated steel pipes 1 and 2.
전열선(6)은 구리선, 니크롬선 등과 같이 전열도가 높은 금속 재질로 이루어진다. 이러한 전열선(6)은 상술한 가이드편(3) 내측의 가이드 홈(3b) 상에 위치하고, 피복형 파형강관(1, 2)의 상호 연결되는 부분의 외주면 상에 코일 형태로 감겨져 있다. 이러한 전열선(6)의 각 단부 상에 전기융착기 등과 같이 전원이 공급되어 전열선(6)이 통전되면 발생되는 전기적인 열 에너지에 의해 각 피복형 파형강관(1, 2)의 상호 연결되는 부분의 외주면 상의 열가소성 재질의 피복층이 녹게 된다.The heating wire 6 is made of a metal material having a high degree of heat transfer, such as copper wire and nichrome wire. This heating wire 6 is located on the guide groove 3b inside the guide piece 3 described above, and is wound in the form of a coil on the outer circumferential surface of the interconnected portions of the coated corrugated steel pipes 1 and 2. The outer circumferential surface of the interconnected portions of each of the corrugated corrugated steel pipes 1 and 2 by electric thermal energy generated when the heating wire 6 is energized, such as an electric fusion machine, on each end of the heating wire 6. The thermoplastic coating layer of the phase is melted.
주입기(5)는 상술한 가이드편(3)의 주입구(3a)에 분리가능하게 결합되어져, 용융 상태의 열가소성 수지를 가이드편(3)의 내측면 상에 주입한다. 이러한 주입기(5)는 용융상태의 열가소성 수지를 압출하는 통상적인 압출장치의 형태이다.The injector 5 is detachably coupled to the injection hole 3a of the guide piece 3 described above, and injects a thermoplastic resin in a molten state onto the inner surface of the guide piece 3. This injector 5 is in the form of a conventional extrusion apparatus for extruding molten thermoplastic resin.
이하, 상기와 같이 구성된 본 발명의 피복형 파형강관의 이음장치를 이용한 피복형 파형강관의 이음방법을 도 3을 참조하여 상세히 설명한다.Hereinafter, a method of jointing a corrugated corrugated steel pipe using a joint of a corrugated corrugated steel pipe of the present invention configured as described above will be described in detail with reference to FIG. 3.
먼저, 피복형 파형강관(1, 2)의 상호 연결되는 부분의 외주면 상에 감겨진 전열선(6) 상으로 전원을 통전시킴으로써, 전열선(6)상에 소정의 전기적인 열 에너지가 발생되도록 한다.First, the electric power is supplied to the heating wire 6 wound on the outer circumferential surface of the interconnected portions of the coated corrugated steel pipes 1 and 2, so that predetermined electrical thermal energy is generated on the heating wire 6.
이러한 전열선(6)의 전기적인 열 에너지에 의해, 피복형 파형강관(1, 2)의 상호 연결되는 부분의 외주면 상에 피복된 열가소성 수지 재질의 피복층은 녹게 된다(S1).By the electrical thermal energy of the heating wire 6, the coating layer made of thermoplastic resin coated on the outer circumferential surface of the interconnected portions of the coated corrugated steel pipes 1 and 2 is melted (S1).
다음, 이렇게 피복형 파형강관(1, 2)의 피복층이 용융된 상태에서, 주입기(5)에 의해 용융 상태의 열가소성 수지(4)가 주입되어 피복형 파형강관(1, 2)의 상호 연결되는 부분의 외주면 상에 도포된다(S2). 이때, 용융 상태의 열가소성 수지(4)가 가이드편(3)의 가이드홈(3b) 상에 충분히 주입된 후에는 주입기(5)를 가이드편(3)의 주입구(3c)로부터 분리하게 된다.Next, in the state in which the coating layers of the corrugated corrugated steel pipes 1 and 2 are melted, the thermoplastic resin 4 in the molten state is injected by the injector 5 so that the corrugated corrugated steel pipes 1 and 2 are interconnected. It is applied on the outer circumferential surface of the part (S2). At this time, after the thermoplastic resin 4 in the molten state is sufficiently injected onto the guide groove 3b of the guide piece 3, the injector 5 is separated from the injection port 3c of the guide piece 3.
이러한 상태에서, 가이드편(3), 피복형 파형강관(1, 2)의 용융된 피복층, 및 주입되는 용융 상태의 열가소성 수지(4)가 열융착된다.In this state, the guide piece 3, the molten coating layer of the corrugated corrugated steel pipes 1 and 2, and the thermoplastic resin 4 in the molten state to be injected are heat-sealed.
이 후에, 소성 시간이 경과하여 냉각되면, 용융 상태의 열가소성 수지 및 피복형 파형강관(1, 2)의 피복층이 고화되어 2 개의 피복형 파형강관(1, 2)은 상호 결합된다(S3).After that, when the firing time elapses and is cooled, the coating layers of the thermoplastic resin and the corrugated corrugated steel pipes 1 and 2 in the molten state are solidified so that the two corrugated corrugated steel pipes 1 and 2 are mutually joined (S3).
이러한 본 발명에 따르면, 피복형 파형강관의 피복층을 소정의 전기적인 열 에너지에 의해 용융시킨 후에, 피복형 파형강관의 피복층과 동일한 재질로 이루어진 열가소성 수지를 그 위에 주입함으로써, 피복형 파형강관의 이음부의 보다 향상된 구조적 강도, 밀봉성, 및 내식성을 달성하는 특징이 있다.According to the present invention, after the coating layer of the corrugated corrugated steel pipe is melted by a predetermined electric thermal energy, the joint of the corrugated corrugated steel pipe is injected by injecting therein a thermoplastic resin made of the same material as the coating layer of the corrugated corrugated steel pipe. It is characterized by achieving negatively improved structural strength, sealability, and corrosion resistance.
상기와 같은 본 발명은, 파형강관의 이음부 상의 밀봉성, 내식성, 및 구조적 강도를 향상시켜 파형강관의 이음부 상에서 발생하는 파손 및 누수 등을 방지하는 매우 뛰어난 효과가 있다.The present invention as described above has a very excellent effect of preventing the breakage and leakage occurring on the joint of the corrugated steel pipe by improving the sealing property, corrosion resistance, and structural strength on the joint of the corrugated steel pipe.
이상에서는, 본 발명을 특정의 바람직한 실시예에 대해서 도시하고 설명하였다. 그러나, 본 발명은 상술한 실시예에만 한정되는 것은 아니며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 이하의 특허청구범위에 기재된 본 발명의 기술적 사상의 요지를 벗어남이 없이 얼마든지 다양하게 변경실시할 수 잇을 것이다.In the above, the present invention has been illustrated and described with respect to certain preferred embodiments. However, the present invention is not limited only to the above-described embodiments, and those skilled in the art may vary without departing from the spirit of the technical idea of the present invention described in the claims below.
