Description
본 발명은 지하에 매설되는 고밀도 폴리에틸렌관에 관한 것으로, 상세하게는 다수의 폴리에틸렌관의 이음을 위해 체결공이 형성된 플랜지를 관의 본체에 용융접착되어, 작업현장에서 용이하게 관연결을 할 수 있는 플랜지가 부착된 고밀도 폴리에틸렌관 및 그 제조방법에 관한 것이다.The present invention relates to a high-density polyethylene pipe embedded in the basement, and in detail, a flange that can be connected to the main body of the pipe by the flange of the fastening hole is formed for the joint of a plurality of polyethylene pipe, the pipe can be easily connected in the workplace It relates to a high-density polyethylene tube and a method for producing the same.
고밀도 폴리에틸레관은 지하에 매설되어 오수나 우수의 수로를 형성하는 것으로, 주로 관본체 다수개를 현장에서 연결하여 사용된다. 통상의 관 연결은 수팽창 고무, 수밀 시트, 접합부위의 강성을 지켜주는 SUS밴드 등으로 연결하는 방법과, 메시형태의 열선으로 관의 단부를 용융접착시키는 전기융착방법 등이 있다.High-density polyethylene pipes are buried underground to form sewage or rainwater channels, and many pipe bodies are used in the field. Common pipe connections include water expansion rubber, watertight sheet, a method of connecting with a SUS band that protects the rigidity of the joint, and an electric welding method for melt bonding the end of the pipe with a mesh-type hot wire.
수팽창 고무 등으로 연결하는 방법은 연결할 관을 정확히 그 단부를 일치시켜 정렬하고, 상기의 연결단부는 절단면이 수직이 되어야 하고 접합면이 벌어지지 않아야 한다. 따라서 연결할 관을 정렬하면 이물질을 제거하고 연결관위의 둘레를 수밀 시트로 감아주며, SUS 밴드로 체결하여 접합시키게 된다.In the method of connecting with water-expanded rubber or the like, the pipes to be connected must be aligned to exactly match their ends, and the connecting ends thereof should be vertical in the cutting plane and not open in the jointing plane. Therefore, when aligning the pipe to be connected, the foreign material is removed, and the circumference of the connection pipe is wrapped with a watertight sheet, which is joined by fastening with a SUS band.
전기융착방법은 각목이나 모래주머니 등으로 연결할 관을 정렬시키고, 이물질을 제거한 후 연결관위에 열선이 그물모양으로 내설된 E/F연결관을 장착한다. 따라서 열선에 통전시키면 열에 의해 두개의 관이 용융접착되는데, 이 때에는 강한 힘을 주어 단부가 잘 접착되도록 하여야 한다.The electric fusion method aligns the pipes to be connected by lumber or sandbags, and removes foreign substances, and then installs the E / F connecting pipes in which the heating wire is installed in a net shape on the connecting pipes. Therefore, when the heating wire is energized, the two tubes are melt-bonded by heat. In this case, a strong force should be applied to ensure that the ends are well bonded.
상기와 같이 종래의 고밀도 폴리에틸렌관의 연결은 모두가 현장에서 실시하는 방법이고, 그 연결의 과정이 복잡하여 관의 정렬이 틀리거나 틈이 생기는 경우 수압이나 지중의 토압에 의해 크랙으로 누수 등의 문제점이 발생할 우려가 있고, 뿐만 아니라 연결작업 완료 후에도 상온에서 시효경화시키기 위한 일정시간이 필요하게 되어 그 시간 동안은 작업을 할 수 없는 문제점이 있게 된다.As described above, the connection of the conventional high-density polyethylene pipe is a method performed by all in the field, and the connection process is complicated, and if the alignment of the pipe is incorrect or a gap occurs, problems such as water leakage or cracking due to earth pressure in the ground occur. There is a possibility that this may occur, as well as a certain time is required for aging hardening at room temperature even after completion of the connection work there is a problem that can not work during that time.
본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 현장에서 간단한 작업만으로 다수의 폴리에틸렌관을 연결할 수 있도록, 관본체의 양단부에 플랜지가 용융접착된 고밀도 폴리에틸렌관 및 이를 제조하는 방법을 제공함에 있다. An object of the present invention is to solve the conventional problems as described above, the high-density polyethylene tube with a flange is melt-bonded at both ends of the tube body so as to connect a plurality of polyethylene tube in a simple operation in the field and a method of manufacturing the same In providing.
이하 본 발명을 첨부 도면에 의해 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

A heated wire mesh 5 is embedded in the flange 7 formed of a fusion pipe 6 recessed with a shrinkage groove 11 parallel to the center of the tube at equal intervals on the outer circumferential surface thereof; Fusion pipe 6 of the flange 7 is characterized in that the extrapolated to both ends of the main body 1 has a structure fused in the fusion unit 12.
도면 중 미설명 부호 8은 SUS 밴드이고, 9는 전원이며, 10은 체결수단이다.In the figure, reference numeral 8 is a SUS band, 9 is a power source, 10 is a fastening means.
이와 같은 구조를 가지는 본 발명의 '플랜지가 부착된 고밀도 폴리에틸렌관'의 제조방법은, 상기 구조를 갖는 플랜지(7)의 융착관(6) 내측으로 고밀도 폴리에틸렌관인 본체(1)의 양단부를 각각 압입시켜 플랜지(7)의 연결판(3)에 밀착되게 하는 단계와; SUS 밴드(8)를 플랜지(7)의 융착관(6)의 외주면에 체결하여 융착관(6)과 본체(1)를 조여주는 단계와; 플랜지(7)의 융착관(6) 내부에 매설된 열선메시(5)의 접속단을 전원(9)에 연결하여 통전시켜 플랜지(7)의 융착관(6) 내측에 돌설된 요철부(4)를 본체(1)의 양단부의 외주면에 융착시켜 접합시키는 단계;를 포함함을 특징으로 한다.In the manufacturing method of the "high density polyethylene pipe with a flange" of this invention which has such a structure, both ends of the main body 1 which is a high density polyethylene pipe are respectively pressed inside the fusion pipe 6 of the flange 7 which has the said structure. To make close contact with the connecting plate (3) of the flange (7); Fastening the SUS band 8 to the outer circumferential surface of the fusion pipe 6 of the flange 7 to tighten the fusion pipe 6 and the main body 1; The concave-convex portion 4 protruding inside the fusion tube 6 of the flange 7 by energizing the connection end of the hot wire mesh 5 embedded in the fusion tube 6 of the flange 7 to the power source 9. And fusion bonding to the outer circumferential surface of both ends of the main body (1).
이와같은 제조방법에 의해 제조된 본 발명의 '플랜지가 부착된 고밀도 폴리에틸렌관'은 양단부에 플랜지(7)가 설치되어 있기 때문에 현장에서 직접 용이하게 관이음을 할 수 있게 된다.The 'high-density polyethylene pipe with a flange' of the present invention manufactured by such a manufacturing method can be easily piped directly in the field because the flange 7 is installed at both ends.
상기에서 언급된 구조를 가지는 플랜지(7)의 구성에 대한 작용과, 본 발명에 의한 제조방법을 상술하면 다음과 같다.The operation of the configuration of the flange 7 having the above-mentioned structure and the manufacturing method according to the present invention will be described below.
우선, 플랜지(7)의 융착관(6) 내측에 고밀도 폴리에틸렌관인 본체(1)의 단부를 압입시키는 단계로서, 플랜지(7)의 융착관(6) 내측면의 요철부(4)가 본체(1) 단부의 외주면을 압지하게 된다. 요철부(4)는 그 단면이 톱니형상을 하고 있어 본체(1)를 압지하기에 용이한 구조를 가지고 플랜지(7)와 본체(1)의 결합을 견고하게 하는 역할을 한다.First, the end of the main body 1, which is a high-density polyethylene tube, is press-fitted into the fusion tube 6 inside the flange 7, so that the uneven portion 4 of the inner surface of the fusion tube 6 of the flange 7 1) The outer peripheral surface of the end is pressed. The concave-convex portion 4 has a sawtooth-shaped cross section, and has a structure that is easy to grip the main body 1, and serves to secure the coupling between the flange 7 and the main body 1.
다음의 단계는 플랜지(7)의 융착관(6)을 본체(1)에 강하게 압지시키는 단계로서, SUS 밴드(8)를 이용하여 융착관(6)을 본체(1)에 조여주게 되는데, 이로써 융착관(6)의 요철부(4)가 본체(1)의 내면에 일정 깊이까지 박히게 된다. 이로써 융착관(6)과 본체(1)는 그 접촉면이 증대되고, 요철부(4)의 돌기 방향이 톱날같이 본체(1)의 양단부의 바깥쪽을 향하여 경사지게 형성되어 있어 플랜지(7)가 쉽게 본체(1)에서부터 빠지지 못하게 하는 역할도 한다.The next step is to strongly press the fusion pipe 6 of the flange (7) to the main body 1, to tighten the fusion pipe (6) to the main body 1 by using the SUS band (8). The uneven portion 4 of the fusion tube 6 is embedded in the inner surface of the main body 1 to a certain depth. As a result, the contact surface of the fusion pipe 6 and the main body 1 is increased, and the projection direction of the uneven portion 4 is formed to be inclined toward the outside of both ends of the main body 1 like a saw blade, so that the flange 7 is easily formed. It also serves to prevent the body (1) from falling out.
그리고, 플랜지(7)의 융착관(6)를 본체(1)에 융착시키는 단계로서, 본 발명의 융착관(6) 내부에는 열선이 메시모양으로 형성된 열선메시(5)가 매설되어 있어 이를 이용하여 본체(1)에 플랜지(7)를 융착시키게 된다. 즉, 도 3에 도시된 바와 같이 열선메시(5)의 접속단을 전원(9)에 연결하여 통전시키면 열선메시(5)에서 발열되어 융착관(6)과 본체(1)가 융착된다. 이 때 플랜지(7)의 융착관(6)의 내측면에 돌설된 요철부(4)는 본체(1)에 압지되면서 융착되어, 표면만 융착되는 것이 아니고 본체(1)의 내부 일정깊이까지 융착되어, 플랜지(7)와 본체(1)가 일체로 성형된 것과 같다. 이와같이 본체(1)와 융착관(6)은 도 5와 도 6에 도시된 바와 같이 융착부(12)에서 일체가 된다.And, in the step of fusing the fusion pipe 6 of the flange 7 to the main body 1, inside the fusion pipe 6 of the present invention is a hot wire mesh (5) in which the hot wire is formed in a mesh shape is embedded therein Thus, the flange 7 is fused to the main body 1. That is, as shown in FIG. 3, when the connection end of the hot wire mesh 5 is connected to the power source 9 and is energized, the hot wire mesh 5 generates heat to fuse the fusion pipe 6 and the main body 1 to each other. At this time, the concave-convex portion 4 protruding on the inner side of the fusion pipe 6 of the flange 7 is press-bonded to the main body 1 to be fused and welded to the inside constant depth of the main body 1, not to the surface. It is as if the flange 7 and the main body 1 were integrally molded. In this way, the main body 1 and the fusion tube 6 are integrated in the fusion portion 12 as shown in FIGS. 5 and 6.
여기서 특히, 융착관(6)을 본체(1)에 압착시켜 조여주면서 융착시키기 위하여 SUS 밴드(8)를 이용할 뿐만 아니라, 융착관(6)의 외주면에 수축홈(11)이 다수개 등간격으로 요설되어 있어, 열선메시(5)에 의해 융착관(6)이 용융되어가면서 융착관(6)의 수축을 용이하게 한다. 즉, 융착관(6)의 수축홈(11) 부분은 용융과 함께 다른 부위보다 함몰이 빠르게 일어나고, 이에 따라 수축홈(11)의 사이의 부분이 수축홈(11) 하부의 함몰과 함께 본체(1) 방향으로 수축의 정도가 증대되어 결국 융착관(6)이 본체(1)를 긴밀하게 조여주게 된다.Here, in particular, not only the SUS band 8 is used to squeeze the fusion pipe 6 to the main body 1 but also to weld the fusion pipe 6, and a plurality of shrinkage grooves 11 are formed at equal intervals on the outer circumferential surface of the fusion pipe 6. In summary, while the fusion tube 6 is melted by the hot wire mesh 5, the fusion tube 6 is easily contracted. That is, the shrinkage groove 11 portion of the fusion tube 6 decays faster than the other portions together with melting, so that the portion between the shrinkage grooves 11 is recessed below the shrinkage groove 11 and the main body ( In the 1) direction, the degree of shrinkage is increased so that the fusion tube 6 tightly tightens the main body 1.
상기와 같이 제조된 본 발명의 '플랜지가 부착된 고밀도 폴리에틸렌관'의 단면은 도 5에 도시된 바와 같고, 이를 이용하여 현장에서 관이음한 상태가 도 7에 도시되어 있다.The cross-section of the 'high-density polyethylene tube with a flange' of the present invention prepared as described above is as shown in Figure 5, using the same is shown in Figure 7 the pipe joint in the field.
본 발명을 이용한 현장에서의 관이음은 종래에 비하여 매우 단순하고, 관이음 후 바로 다른 작업을 수행할 수 있어 작업의 효율이 증대된다. 즉, 본 발명을 이용한 관이음은 연결하고자 하는 '플랜지가 부착된 고밀도 폴리에틸렌관'을 각각의 플랜지(7)의 연결판(3)의 체결공(2)을 맞추어 나란히 정렬시키고, 연통된 체결공(2)에 볼트와 너트 등의 체결수단(10)으로 체결하여 연결한다.The pipe joint in the field using the present invention is very simple as compared to the prior art, it is possible to perform another operation immediately after the pipe joint is increased the efficiency of the work. That is, the pipe joint using the present invention aligns the 'high-density polyethylene pipe with a flange' to be connected to each other by aligning the fastening holes (2) of the connecting plate (3) of each flange (7), connected fastening holes (2) is fastened by means of fastening means (10) such as bolts and nuts.
이와 같이 본 발명은 현장에서 관이음하기가 매우 편리하고, 관이음 후 매설작업을 바로 시행할 수 있어 작업의 효율이 증대된다.As such, the present invention is very convenient to the pipe joint in the field, can be carried out immediately after the pipe joint is increased the efficiency of the work.
이와같이 된 본 발명은 고밀도 폴리에틸렌관의 양단부에 플랜지(7)가 융착되어 일체형으로 형성됨으로써, 작업 현장에서 플랜지(7)를 맞추고 이에 형성된 체결공(2)에 볼트와 너트 등의 체결수단으로 이음하여 관 연결할 수 있기 때문에, 작업이 용이하고 작업 효율이 증대되는 효과가 있다.According to the present invention, the flange 7 is fused to both ends of the high-density polyethylene tube so that the flange 7 is integrally formed, so that the flange 7 is fitted at the work site, and the fastening hole 2 is connected to the fastening hole 2 formed therein. Since the pipe can be connected, the work is easy and the work efficiency is increased.
