본 발명은 수지파형강관의 연결구조에 관한 것으로, 더욱 상세하게는 전기융착시트와 수지파형강관의 접촉면을 확장시켜 기밀상을 향상시킨 수지파형강관의 연결구조에 관한 것이다.The present invention relates to a connection structure of a resin corrugated steel pipe, and more particularly, to a connection structure of a resin corrugated steel pipe having an improved airtight phase by extending the contact surface of the electrofusion sheet and the resin corrugated steel pipe.

일반적으로 강관은 강판을 말아 성형하거나 혹은 강판을 나선형으로 말아 파형강관으로 만들어 사용하게 된다. 이러한 파형강관은 높은 외압강도, 내구성 및 시공성이 우수하여 각종 생활오수 등의 배출을 안내하는 흄관 대용으로 사용되거나 공기를 포함하는 각종 유체의 흐름을 안내하는 덕트로 사용되고 있다. 파형강관중 수지파형강관은 수지를 피복한 것으로서 근래들어 많이 사용된다.In general, steel pipes are formed by rolling steel sheets or spirally rolling steel sheets to be used as corrugated steel tubes. These corrugated steel pipes are used as a substitute for a fume pipe for guiding the discharge of various domestic wastewaters due to high external pressure strength, durability, and workability, or as a duct for guiding the flow of various fluids including air. Among corrugated steel pipes, resin corrugated steel pipes are resin coated and are used in recent years.

이러한 파형강관은 시공거리에 따라 복수 개가 구비되어 서로 연결된다. 파형강관을 서로 연결하기 위한 종래의 연결구조는 도 1 및 도2에 도시된 바와 같이, 서로 연결되는 두 파형강관(100)의 선단부를 서로 맞댄 상태에서 그 외측에 민자형의 전기융착시트(110)를 감아 고정하고, 그 외측에 금속재로 된 커플링 밴드(120)를 감은 후 커플링 밴드(120)의 양단부에 형성된 플랜지부(121)를 서로 맞댄 후 볼트(130)와 너트(140)를 이용해 플랜지부(121)를 견고히 조이게 된다. The corrugated steel pipe is provided with a plurality depending on the construction distance is connected to each other. Conventional connection structure for connecting corrugated steel pipes as shown in Figures 1 and 2, the front end of the two corrugated steel pipes 100 to be connected to each other in the state of the privately-shaped electrofusion sheet 110 on the outside thereof Winding and fixing, and after winding the coupling band 120 made of a metal material on the outside thereof to face the flange portion 121 formed at both ends of the coupling band 120 to each other and then using the bolt 130 and the nut 140 The flange 121 is firmly tightened.

그러나 전술한 바와 같이 구성된 종래의 강관 연결구조의 경우, 민자형 전기융착시트와 한 쌍의 커플링 밴드만으로 고정된다. 따라서 파형강관이 유동되는 경우 파형강관의 외측에 융착되어 있는 전기융착시트가 떨어지면서 파형강관의 굴곡진 외측과 전기융착시트 사이에 틈새를 발생하게 되고 그 틈새로 물이 새어나가는 누수현상이 발생하게 되는 문제점이 있다.However, in the case of the conventional steel pipe connection structure configured as described above, it is fixed only by the private-shaped electrofusion sheet and a pair of coupling bands. Therefore, when the corrugated steel pipe is flowed, the fusion sheet which is fused to the outer side of the corrugated steel pipe falls and a gap is generated between the curved outer side of the corrugated steel pipe and the electric fusion sheet, and water leaks into the gap. There is a problem.

이에 본 발명은 전술한 바와 같은 종래의 제반 문제점을 해소하기 위하여 안출된 것으로, 서로 연결되는 한 쌍의 수지파형강관 선단부와 전기융착시트와의 접촉면을 확장시킴으로써, 기밀성을 향상시킬 수 있는 수지파형강관의 연결구조를 제 공하는데 그 목적이 있다.Accordingly, the present invention has been made in order to solve the conventional problems as described above, by extending the contact surface of the pair of resin corrugated steel pipe ends connected to each other and the electrofusion sheet, the resin corrugated steel pipe that can improve the airtightness The purpose is to provide a connection structure.

전술한 바와 같은 목적을 달성하기 위해 본 발명에 따른 수지파형강관의 연결구조는, 서로 연결되는 두 수지파형강관의 선단부 외측에 전기융착시트를 감아 고정하고, 전기융착시트의 외측을 금속재로 된 커플링 밴드로 감싸고 커플링 밴드의 양단부에 각각 형성된 플랜지부를 서로 맞댄 후, 볼트와 너트를 이용해 플랜지부를 체결하는 것에 있어서, 전기융착시트는 양쪽에 수지파형강관의 선단부가 끼워지는 강관 끼움홈이 양측 방향으로 각각 개방되게 형성되어, 수지파형강관의 선단부 3면 즉, 내,외측면 그리고 선단면이 강관 끼움홈의 내측 3면에 각각 접촉되도록 이루어진 것에 기술적 특징이 있다.In order to achieve the object as described above, the connection structure of the resin corrugated steel pipe according to the present invention, the electric fusion sheet is wound around the outer end of the two resin corrugated steel pipes connected to each other and fixed, and the outer side of the fusion sheet made of metal Wrapping with a ring band and facing the flanges respectively formed at both ends of the coupling band, and then fastening the flanges using bolts and nuts, the electrofusion sheet has a steel pipe fitting groove in which the front end of the resin corrugated steel pipe is fitted on both sides. It is formed so as to be open in both directions, and the technical features that the three ends of the resin wave steel pipe, that is, the inner, outer side and the front end surface are in contact with the inner three sides of the steel pipe fitting groove, respectively.

이하, 본 발명에 따른 수지파형강관의 연결구조의 바람직한 실시예를 통하여 전술한 바와 같은 구성들의 특징과 그 작용을 보다 상세히 설명하기로 한다.Hereinafter, the characteristics and the operation of the above-described configuration through the preferred embodiment of the connection structure of the resin corrugated steel pipe according to the present invention will be described in detail.

도 3 및 도 4에 도시된 바와 같이, 본 발명에 따른 수지파형강관의 연결구조는, 서로 연결되는 두 수지파형강관(10)의 선단부 외측에 전기융착시트(20)를 감아 고정하고, 전기융착시트(20)의 외측에 금속재로 된 커플링 밴드(30)를 감고 볼트(40)와 너트(50)를 이용해 커플링 밴드(30)를 견고히 조이도록 이루어진다.As shown in Figures 3 and 4, the connection structure of the resin wave steel pipe according to the present invention, the electric fusion sheet 20 is wound around the outer end of the two resin wave steel pipe 10 connected to each other and fixed, electrofusion The outer side of the seat 20 is made of metal coupling band 30 is made to tighten the coupling band 30 by using the bolt 40 and the nut 50.

전술한 전기융착시트(20)는 전체적으로 I자형으로 형성된 것으로, 양쪽에 수지파형강관(10)의 선단부가 끼워지는 강관 끼움홈(20a)이 양측 방향으로 각각 개방 되게 형성된다.The above-mentioned electrofusion sheet 20 is formed in an I-shape as a whole, and the steel pipe fitting grooves 20a into which the front end portions of the resin-corrugated steel pipe 10 are fitted are opened in both directions.

이처럼 수지파형강관(10)을 강관 끼움홈(20a)에 끼우게 되면, 수지파형강관(10)의 선단부 내,외측면 그리고 선단면이 강관 끼움홈(20a)의 내측 3면에 각각 접촉됨에 따라 종래에서와 같이 평면형 전기융착시트가 파형강관의 외측면에만 접촉될 때보다 기밀성이 향상되어 누수의 염려가 없게 된다.When the resin wave steel tube 10 is inserted into the steel pipe fitting groove 20a, the inner, outer and front ends of the resin wave steel tube 10 come into contact with the inner three sides of the steel pipe fitting groove 20a, respectively. As in the prior art, the airtightness is improved compared to when the planar electrofusion sheet is in contact only with the outer surface of the corrugated steel pipe, so there is no fear of leakage.

한편, 전기융착시트(20)는 전기가 인가될 때 융착에 의해 수지파형강관(10)의 내,외측면 및 선단면에 접합된다.On the other hand, the electric fusion sheet 20 is bonded to the inner, outer and front end surface of the resin wave steel pipe 10 by fusion when electricity is applied.

전술한 커플링 밴드(30)는 종래의 것과 동일한 형태로 형성되며 전기융착시트(20)를 수지파형강관(10)의 선단에 각각 밀착시키고 두 수지파형강관(10)을 고정시키는 역할을 하는 것으로, 수지파형강관(10)의 라운딩된 외측면을 감싸도록 라운딩되며 양단부에 플랜지부(31)가 각각 형성된다.The above-mentioned coupling band 30 is formed in the same shape as the conventional one and serves to closely adhere the electric fusion sheet 20 to the front end of the resin corrugated steel pipe 10 and to fix the two resin corrugated steel pipes 10. , And rounded so as to surround the rounded outer surface of the resin corrugated steel pipe 10, and flange portions 31 are formed at both ends thereof.

따라서, 전기융착시트(20)의 외측에 커플링 밴드(30)를 감싼 상태에서 두 플랜지부(31)를 서로 맞대고, 플랜지부(31)에 형성된 볼트 관통홀(31a)에 볼트(40)를 관통시키고 너트(50)를 조여줌으로써, 커플링 밴드(30)의 두 플랜지부(31)가 견고히 결합된다. Therefore, the two flange parts 31 abut each other in a state in which the coupling band 30 is wrapped on the outer side of the fusion sheet 20, and the bolt 40 is inserted into the bolt through hole 31 a formed in the flange part 31. By penetrating and tightening the nut 50, the two flange portions 31 of the coupling band 30 are firmly engaged.

이하에서는 전술한 바와 같이 구성된 본 발명 수지파형강관의 연결구조에 따라 수지파형강관을 연결하는 과정을 도 5를 참조로 상세히 설명하기로 한다.Hereinafter, a process of connecting the resin wave steel pipe according to the connection structure of the resin wave steel pipe of the present invention configured as described above will be described in detail with reference to FIG. 5.

먼저, 하나의 수지파형강관(10) 선단을 I자 형태로 형성된 전기융착시트(20)의 일측에 형성된 강관 끼움홈(20a)에 견고히 끼우고 다른 하나의 수지파형 강관(10) 선단을 전기융착시트(20)의 타측에 형성된 강관 끼움홈(20a)에 견고히 끼워, 수지파형강관(10)의 3면 즉 내,외측면 및 선단면이 전기융착시트(20)의 강관 끼움홈(20a) 내측 3면에 각각 밀착되도록 한다. First, the end of one resin wave steel tube 10 is firmly inserted into the steel pipe fitting groove 20a formed on one side of the electric fusion sheet 20 formed in the I-shape, and the other end of the resin wave steel tube 10 is electrofused. The steel pipe fitting groove 20a formed on the other side of the sheet 20 is firmly inserted, and the three surfaces of the resin wave steel tube 10, that is, the inner and outer surfaces and the front end surface are inside the steel pipe fitting groove 20a of the electrofusion sheet 20. Make sure they are in close contact with each of the three sides

그리고 나서, 커플링 밴드(30)로 전기융착시트(20)의 외측면을 감싸 두 플랜지부(31)를 서로 맞대고, 볼트(40)를 플랜지부(31)의 볼트 관통홀(31a)을 관통시킨 후 너트(50)로 조여줌으로써 두 플랜지부(31)가 견고히 결합되면서 두 수지파형강관(10)이 견고히 연결 고정된다.Then, the outer surface of the fusion sheet 20 is wrapped with the coupling band 30 so that the two flange portions 31 abut each other, and the bolt 40 passes through the bolt through hole 31a of the flange portion 31. After tightening with the nut 50, the two flange portions 31 are firmly coupled, and the two resin wave steel pipes 10 are firmly connected and fixed.

이와 동시에 전기융착시트(20)도 수지파형강관(10)의 내,외측면 및 선단면에 견고히 밀착됨으로써 기밀성이 향상된다. 한편, 전기융착시트(20)는 전원 인가시 융착에 의해 수지파형강관(10)에 접합된다. At the same time, the electrofusion sheet 20 is also tightly adhered to the inner, outer and front end surfaces of the resin corrugated steel pipe 10, thereby improving airtightness. On the other hand, the electrofusion sheet 20 is bonded to the resin wave steel pipe 10 by fusion when the power is applied.

이상과 같이 본 발명의 바람직한 실시예에 따른 수지파형강관의 연결구조를 첨부된 도면을 참조로 설명하였으나, 본 발명은 본 명세서에 상세히 설명된 실시예와 도면에 한정되지 아니하며, 발명의 기술사상 범위 내에서 다양한 변형이 이루어질 수 있다.As described above with reference to the accompanying drawings of the resin corrugated steel pipe according to a preferred embodiment of the present invention, the present invention is not limited to the embodiments and drawings described in detail herein, the technical scope of the invention Various modifications can be made within.

예컨대, 커플링 밴드는 반원형 형태로 형성되고 각 커플링 밴드의 양단부에 플랜지부가 각각 형성되는 것도 가능하다. 이 경우에는 두 개의 커플링 밴드가 서로 대향되게 수지파형강관을 감싼 상태에서 서로 마주보는 플랜지부가 볼트와 너트에 의해 견고히 결합된다.For example, the coupling band may be formed in a semicircular shape, and flange portions may be formed at both ends of each coupling band. In this case, the flanges facing each other are tightly coupled by bolts and nuts while the two coupling bands are wrapped around the resin wave steel pipe to face each other.

전술한 바와 같이 구성된 본 발명 수지파형강관의 연결구조에 따르면, I자형 전기융착시트의 양측에 형성된 강관 끼움홈에 두 수지파형강관의 선단부를 각각 끼우도록 이루어짐으로써, 수지파형강관의 선단부 3면 즉 내,외측면 및 선단면이 강관 끼움홈의 내부 3면에 접촉됨에 따라 종래에서와 같이 전기융착시트가 수지파형강관의 외측면에만 접촉될 때보다 기밀성이 향상되어 누수를 효과적으로 예방할 수 있다.According to the connection structure of the resin corrugated steel pipe of the present invention configured as described above, the front end portions of the two resin corrugated steel pipes are respectively inserted into the steel pipe fitting grooves formed on both sides of the I-shaped electrofusion sheet, so that the three ends of the resin corrugated steel pipe As the inner and outer surfaces and the front end face contact the three inner surfaces of the steel pipe fitting groove, airtightness is improved as compared to when the electric fusion sheet contacts only the outer surface of the resin corrugated steel pipe as in the prior art, thereby effectively preventing leakage.
