As shown in FIG. 2, the present invention provides a watertight sheet 180 surrounding the outer diameter of the corrugated steel pipe 120, a fastening band 140 surrounding the outer diameter of the watertight sheet 180, and the fastening band 140. The fastening member 160 formed at the tip of the, the plurality of through holes 166 formed in the fastening member 160, the split through the bolt 162 through the through hole 166 coupled to the nut 64 In the corrugated steel pipe coupling band 100, the watertight sheet 180 and the fastening band 140 is formed integrally, the watertight sheet 180 is an injection molding machine on the inner surface of the fastening band 140 Foam 240 is applied to provide a sheet integral corrugated steel pipe coupling band, characterized in that coupled to the inner surface of the fastening band 140.

상기 수밀성시트(180)는 열가소성 폴리우레탄이 주로 사용된다. 폴리우레탄 수지란 알콜기와 아이소사이안산기의 결합으로 만들어진 우레탄결합으로 결합된 고분자 화합물을 말한다. The watertight sheet 180 is mainly used thermoplastic polyurethane. Polyurethane resin refers to a high molecular compound bonded by a urethane bond made of a combination of an alcohol group and an isocyanic acid group.

또한, 수밀성시트(180)의 소재로서 자주사용되는 흡수팽창성 수지는 자기무게의 수십배 또는 수백배에 이르는 양의 물을 비가역적으로 흡수할수 있는 비닐알콜과 아크릴산을 코모노머(comonomer)로 한 공중합체를 주성분으로 하는 고흡수성 폴리머 등이 있다. 기타 많은 고흡수성 폴리머를 사용할 수도 있으나 성형시에 받는 열에 대해 그 성능을 잃지 않도록 충분한 내열성을 갖는 것이 필요하다.In addition, the water-expandable resin, which is often used as a material for the watertight sheet 180, is a copolymer of vinyl alcohol and acrylic acid as a comonomer capable of irreversibly absorbing water in amounts of tens or hundreds of times its own weight. And superabsorbent polymers containing as a main component. Many other superabsorbent polymers may also be used, but it is necessary to have sufficient heat resistance so as not to lose their performance against the heat received during molding.

또한, 성형시에 파형강관(120)의 주면에 밀착할 수 있도록 충분한 유연성을 갖는 것으로서 더욱이 수지소재의 흡수팽창에 따라 외관의 두께가 충분하게 늘어나도록 한 이완가능한 조직으로 된 것이 좋다.  In addition, it has a sufficient flexibility to be in close contact with the main surface of the corrugated steel pipe 120 during molding, and furthermore, it is preferable to have a relaxed structure in which the thickness of the appearance is sufficiently increased according to the absorption expansion of the resin material.

본 발명의 파형강관 커플링 밴드(100)에 성형시의 성형압으로 강하고 견고하게 융착된 수밀성시트(180)는 종래의 접착제로 접착된 것과 비교해서 그 이상으로 파형강관 커플링 밴드(100)의 내부면에 강하고 견고하게 일체화되어 있기 때문에 접속 대상 파형강관(120)를 끼워 맞출 때에 위치의 어긋남을 일으킬 우려가 적다.
The watertight sheet 180, which is strongly and firmly fused at molding pressure to the corrugated steel pipe coupling band 100 of the present invention, is more than that of the corrugated steel pipe coupling band 100 compared with that of a conventional adhesive. Since the inner surface is strongly and firmly integrated, there is little possibility that the position shift occurs when the corrugated steel pipe 120 to be connected is fitted.

상기 체결밴드(140)는 상기 수밀성시트(180)의 외경을 감싸며 상기 체결밴드(140)의 선단에는 체결부재(160)가 결합된다. 상기 체결밴드(140)는 알류미늄 도금이 된 스테인리스로 제작되어 수분과 오염물 등에 의한 부식이나 파손에 강하다. 상기 체결밴드(140)의 양단에는 체결부재(160)가 마련되고, 상기 체결부재(160)의 일 측면에는 하나 이상의 관통공(166)이 형성된다. 상기 관통공(166)을 관통한 볼트(162)는 너트(64)와 결합되어 상기 체결밴드(140)가 수밀성시트(180)에 밀착되도록 조이는 기능을 한다.The fastening band 140 surrounds the outer diameter of the watertight seat 180 and a fastening member 160 is coupled to the front end of the fastening band 140. The fastening band 140 is made of aluminium-plated stainless steel is resistant to corrosion and damage caused by moisture and contaminants. Fastening members 160 are provided at both ends of the fastening band 140, and at least one through hole 166 is formed at one side of the fastening member 160. The bolt 162 penetrating the through hole 166 is coupled to the nut 64 to tighten the fastening band 140 to be in close contact with the watertight seat 180.

한편, 상기 수밀성시트(180)와 체결밴드(140)는 일체로 형성되는 것이 바람직하다.On the other hand, the watertight sheet 180 and the fastening band 140 is preferably formed integrally.

본 발명에 따른 시트 일체형 파형강관 커플링 밴드는 발포체(240)를 파형강관 커플링 밴드(100)의 내부에 발포하여 상기 발포체(240)를 상기 파형강관 커플링 밴드(100)에 도포함으로써 상기 파형강관 커플링 밴드(100)과 일체로 형성되는 수밀성시트(180)가 형성 된다.Sheet-integrated corrugated steel pipe coupling band according to the present invention by foaming the foam 240 inside the corrugated steel pipe coupling band 100 by applying the foam 240 to the corrugated steel pipe coupling band 100 to the corrugated The watertight sheet 180 integrally formed with the steel pipe coupling band 100 is formed.

In addition, the foam 240 is introduced into the foaming gap 280 through the gate 260 of the mold 200 by using the launcher 280, and the mold 200 is cooled and the mold 240 after the foam 240 is hardened. ) And the corrugated steel pipe coupling band (100).

상기 파형강관 커플링 밴드(100)의 모양과 대응하여 구비된 발포성형장치에 있어서 폴리우레탄 금형(200)은 반응 혼합물을 받아서 분산시키며, 정확한 온도를 유지하고 반응열을 빼앗고, 반응압력을 흡수하며, 원료의 누출을 막고 공기를 빼내어 삽입물을 놓고 고정시킨다.In the foam molding apparatus provided corresponding to the shape of the corrugated steel pipe coupling band 100, the polyurethane mold 200 receives and disperses the reaction mixture, maintains the correct temperature, takes the heat of reaction, absorbs the reaction pressure, Prevent leakage of the raw material, vent the air, and place and insert the insert.

또한, 대량 생산을 위해 사용되는 금형(200)은 대체로 금속으로 만들어지며 직접적으로 가열이 가능해야 하며, 짧은 기간동안만 사용하는 금형은 합성수지로 된 금형을 사용할 수 있고 뜨거운 공기나 반응열을 이용하여 가열할 수 있다. In addition, the mold 200 used for mass production is generally made of metal and should be directly heated. The mold used only for a short time may use a mold made of synthetic resin and heated using hot air or reaction heat. can do.

상기 이형제는 발포체(240)를 금형(200)에 넣기 전에 스프레이로 금형(200)에 도포하여, 특정 폴리우레탄과 몰드의 표면 재료와 잘 조화가 되도록 하여 폼을 손상없이 떼어낼 수 있도록 한다.
The release agent is applied to the mold 200 by spraying the foam 240 into the mold 200, so that the foam 240 can be in harmony with the surface material of the specific polyurethane and the mold so that the foam can be removed without damage.

도 5에 도시된 바와 같이, 본 발명에 따른 시트 일체형 파형강관 커플링 밴드(100)는 두 개의 파형강관(120)의 양단을 인접하도록 설치하고, 상기 파형강관 커플링 밴드(100)를 상기 파형강관(120)의 외경을 감싸도록 한 후에 체결밴드(140)의 체결부재(160)가 인접할 수 있도록 배치한다. 또한, 인접한 체결부재(160)에 관통된 가운데 관통공(166)에 길이가 긴 볼트(62)를 사용하여 상기 체결부재(160)가 더욱 가까이 좁혀지도록 조인다.As shown in FIG. 5, the sheet-integrated corrugated steel pipe coupling band 100 according to the present invention is installed so that both ends of two corrugated steel pipes 120 are adjacent to each other, and the corrugated steel pipe coupling band 100 is formed into the corrugated steel pipe coupling band 100. After wrapping the outer diameter of the steel pipe 120 is disposed so that the fastening member 160 of the fastening band 140 is adjacent. In addition, the fastening member 160 is tightened by using a long bolt 62 in the middle through hole 166 penetrating the adjacent fastening member 160 to be narrowed closer.

상기 체결부재(160)에 결합된 가운데 볼트(162)를 조인 뒤에 양옆의 관통공(166)에 짧은 볼트(162)를 관통시켜 상기 체결부재(160)가 더욱 가까이 근접하도록 조인다.After tightening the central bolt 162 coupled to the fastening member 160, the short bolt 162 penetrates the through holes 166 on both sides thereof, and tightens the fastening member 160 to be closer to each other.

상기 체결부재(160)가 수직이 되도록 상기 볼트(162)를 조여서 상기 체결부재(160)와 상기 파형강관(120)이 밀착되도록 한다. Tightening the bolt 162 so that the fastening member 160 is perpendicular to the fastening member 160 and the corrugated steel pipe 120 is in close contact.

전술한 방법에 따라 결합된 파형강관 커플링 밴드(100)는 종래의 파형강관 커플링 밴드(10)보다 작업시간과 작업능률이 뛰어나고, 작은 인력으로 결합이 가능하다. 또한, 수밀성시트(180)와 체결밴드(140)가 일체로 형성되어 있는바 내부의 수분이 파형강관(120)의 양단이 만나는 부분에서 외부로 유출되는 것을 방지한다.The corrugated steel pipe coupling band 100 coupled in accordance with the above-described method is superior in working time and work efficiency than the conventional corrugated steel pipe coupling band 10, and can be combined with a small manpower. In addition, the watertightness sheet 180 and the fastening band 140 are integrally formed to prevent the water from flowing out to the outside at portions where both ends of the corrugated steel pipe 120 meet.
