본 발명은 플랜지형 피복파형강관의 제조설비에 관한 것으로, 특히 파형강관(corrugated steel pipe)의 내주표면과 외주표면에 다중의 수지층을 피복하여 오수, 폐수, 하수를 처리하는 용도로 사용될 때 피복한 수지층의 박리를 최소The present invention relates to a manufacturing facility for a flange-type coated corrugated steel pipe, particularly when used for treating sewage, wastewater, and sewage by coating multiple resin layers on the inner and outer circumferential surfaces of a corrugated steel pipe. Minimum peeling of one resin layer

화시키고, 양 끝단에 플랜지를 구비하여 결합성 및 작업성이 우수한 플랜지형 피복파형강관의 제조설비에 관한 것이다.It relates to a manufacturing facility for a flanged clad corrugated steel pipe with excellent bonding properties and workability by providing flanges at both ends.

일반적으로 파형강관은 토목분야에서 오수/폐수의 배수로와, 생활용수 또는 산업용수의 급수로 또는, 건축분야에서 중공거푸집이나 건축슈트로서 널리 사용되는 부재이다. 특히, 파형강관은 건축분야에서 증가하고 있는 인력난과 비용 및 환경문제에 대한 인식의 증대로 말미암아 기존의 콘크리트 배수관의 대체 자재로서, 일반 콘크리트형 배수관의 중량에 비해서, 상대적으로 가볍지만 높은 외압강도와 구조적 안정성, 내구성, 경제성, 조립성 및 생산성을 제공하고, 원하는 직경과 길이로 쉽게 제작이 가능하다.In general, a corrugated steel pipe is a member widely used as a drainage channel of sewage/waste water in the civil engineering field, a water supply channel for living or industrial water, or a hollow formwork or a building suit in the construction field. In particular, corrugated steel pipe is a substitute material for the existing concrete drainage pipe due to the increasing awareness of the manpower shortage, cost, and environmental problems in the construction field. It provides structural stability, durability, economy, assembly and productivity, and can be easily manufactured in a desired diameter and length.

도 1에 도시된 바와 같이, 파형강관은 용융 아연도금 강판을 롤러형 다이로 경사지게 이송시켜서 강판에 산과 골로 이루어진 파형을 형성한 후, 가이드 롤러와 성형 롤러에 의해서 스파이럴 스트립 형상을 갖게 되고, 용접 결합 또는 판금 결합에 의해서 측변 접촉부들이 서로 결합됨으로써, 일정한 직경의 연속적인 스파이럴 파이프 형상의 본체(1,1')를 갖는다.이런 파형강관의 본체(1, 1')는 애뉼라밴드(5, 6 : annular band)를 이용하기 위한 재굴곡 공정을 통과하면서, 본체 중앙부(2)에 스파이럴형 산과 골을 갖고, 양 끝단부(3)에 일자형 산과 골을 갖는다. 그리고, 파형강관의 본체(1, 1')는 일정한 길이, 예컨대 대략 길이 6미터로 절단된 후, 밀봉재를 칠하는 등의 마무리 가공 과정을 거쳐 하나의 파트로 완성된다. 이렇게 완성된 파형강관 파트들은 실제 토목분야 또는 건축분야에서 사용될 때, 길이 방향으로 배관된다.특히, 배관시 관이음 수단으로 사용되는 애뉼라밴드(5, 6)는 반환형의 밴드들로서, 끝단부 또는 그 근처에 고정 형성된 연장단들(7, 8)을 각각 스터드 볼트와 너트로 체결함으로써, 본체들(1, 1')을 관 연결시키도록 되어 있다.그러나, 종래의 피복강관은 애뉼라밴드에 의한 관이음 방식을 취함으로써, 본체들간의 축방향이 서로 일치하지 않을 경우 양호하지 못한 결합상태를 유지하거나, 본체들을 배관하는데 많은 시간 소요가 뒤따르고, 비효율적인 배관작업 환경을 제공하는 단점이 있다.또한, 종래의 피복강관은 애뉼라밴드를 이용하기 때문에 플랜지 방식과 비교할 때, 내압 발생시 수밀성 유지가 어렵고, 비교적 강관들 간의 결합력이 약하기 때문에, 결합부위에 변형이 발생될 위험이 있다.따라서, 근래 들어 양 끝단에 플랜지를 부착시킨 파형강관의 시제품이 개발되고 있으나, 이는 대구경을 갖는 본체의As shown in Fig. 1, the corrugated steel pipe forms a corrugation composed of mountains and valleys on the steel sheet by transferring the hot-dip galvanized steel sheet obliquely with a roller-type die, and then has a spiral strip shape by a guide roller and a forming roller, and is welded together Alternatively, the side contact portions are coupled to each other by means of sheet metal coupling, so that the body 1, 1' in the shape of a continuous spiral pipe with a constant diameter is obtained. : While passing through the re-bending process for using an annular band), it has spiral-shaped peaks and troughs in the central part of the body (2), and straight peaks and troughs at both ends (3). In addition, the main bodies 1 and 1' of the corrugated steel pipe are cut to a predetermined length, for example, approximately 6 meters in length, and then go through a finishing process such as applying a sealing material to complete one part. The corrugated steel pipe parts thus completed are actually piped in the longitudinal direction when used in the civil engineering field or construction field. In particular, the annular bands 5 and 6 used as pipe joint means during piping are circular bands, and By fastening the extension ends (7, 8) fixedly formed in the vicinity thereof with stud bolts and nuts, respectively, the main bodies (1, 1') are pipe-connected. By adopting a pipe joint method by .In addition, since the conventional coated steel pipe uses an annular band compared to the flange method, it is difficult to maintain watertightness when internal pressure is generated, and since the bonding force between the steel pipes is relatively weak, there is a risk of deformation at the bonding site. Therefore, Recently, a prototype of a corrugated steel pipe with flanges attached to both ends has been developed, but this

외경에 플랜지를 수동으로 용접하여 부착하는 방법으로 제작되고 있으며, 따라서 대량 생산을 위한 설비의 부재로 인하여 제작 단가가 매우 높고, 이중 코팅된 고품질의 제품을 양산시킬 수 없는 문제점이 있다.특히, 종래의 파형강관은 플랜지를 본체에 용접하여 부착하기 때문에 용접 부위에 부식이 발생되기 쉬우며, 이는 건It is manufactured by manually welding and attaching a flange to the outer diameter. Therefore, the manufacturing cost is very high due to the absence of equipment for mass production, and there are problems in that it is not possible to mass-produce a double-coated high-quality product. Corrosion easily occurs in the welded area because the corrugated steel pipe of

축용도 또는 토목용도로 사용되는 파형강관의 특성상 매우 큰 문제점으로 야기되고 있다.또한, 종래에는 파형강관에 피복을 한 피복강관의 제품들이 강관 제품으로 속속 출하되고 있으나, 이는 금속표면 또는 도금표면 위에 금속과 다른 재질의 수지가 피복되어 층(layer)을 형성하기 때문에, 소정 사용 시간이 경과한 피복강관의 경우, 수지층이 강관으로부터 이격되거나 박리되는 형상을 발생시킨다.특히, 종래의 피복파형강관은 다수의 나사골 또는 나사산에 의한 절곡 나선형 표면 형상을 갖기 때문에, 균일한 두께의 수지층을 외주표면에 형성하기 어렵거나, 피복 작업이 매우 번거럽고 대량 생산이 어려워 상대적으로 제조 단가가 고가인 단점이 있다.The characteristics of the corrugated steel pipe used for shaft or civil engineering are causing a very big problem. Also, conventionally, the products of the coated steel pipe coated with the corrugated steel pipe are shipped one after another as steel pipe products, but this is on the metal surface or the plated surface. Since the resin of a material different from the metal is coated to form a layer, in the case of a coated steel pipe after a predetermined usage time has elapsed, a shape is generated in which the resin layer is separated from or peeled off from the steel pipe. Since silver has a spiral surface shape bent by a number of threads or threads, it is difficult to form a resin layer of uniform thickness on the outer peripheral surface, or the coating operation is very cumbersome and mass production is difficult, so the manufacturing cost is relatively high. there is.

상기한 종래 기술들의 단점을 고려할 때, 가격과 생산성의 입장에서 대량 생산을 위한 설비의 개발이 시급한 실정인것이다.Considering the disadvantages of the prior art, it is an urgent situation to develop a facility for mass production from the standpoint of price and productivity.

이런 파형강관의 본체(1, 1')는 애뉼라밴드(5, 6 : annular band)를 이용하기 위한 재굴곡 공정을 통과하면서, 본체중앙부(2)에 스파이럴형 산과 골을 갖고, 양 끝단부(3)에 일자형 산과 골을 갖는다. 그리고, 파형강관의 본체(1, 1')는 일정한 길이, 예컨대 대략 길이 6미터로 절단된 후, 밀봉재를 칠하는 등의 마무리 가공 과정을 거쳐 하나의 파트로 완성된다. 이렇게 완성된 파형강관 파트들은 실제 토목분야 또는 건축분야에서 사용될 때, 길이 방향으로 배관된다.The body (1, 1') of this corrugated steel pipe has a spiral-shaped mountain and a valley in the central part of the body (2) while passing through a re-bending process for using an annular band (5, 6: annular band), and both ends (3) has straight peaks and valleys. In addition, the main bodies 1 and 1' of the corrugated steel pipe are cut to a predetermined length, for example, approximately 6 meters in length, and then go through a finishing process such as applying a sealing material to complete one part. The corrugated steel pipe parts thus completed are actually piped in the longitudinal direction when used in the civil engineering field or the building field.

특히, 배관시 관이음 수단으로 사용되는 애뉼라밴드(5, 6)는 반환형의 밴드들로서, 끝단부 또는 그 근처에 고정 형성된 연장단들(7, 8)을 각각 스터드 볼트와 너트로 체결함으로써, 본체들(1, 1')을 관 연결시키도록 되어 있다.In particular, the annular bands (5, 6) used as pipe joint means during piping are return-type bands, and by fastening the extension ends (7, 8) fixedly formed at or near the ends with stud bolts and nuts, respectively, It is adapted to connect the bodies 1, 1' by a tube.

그러나, 종래의 피복강관은 애뉼라밴드에 의한 관이음 방식을 취함으로써, 본체들간의 축방향이 서로 일치하지 않을 경우 양호하지 못한 결합상태를 유지하거나, 본체들을 배관하는데 많은 시간 소요가 뒤따르고, 비효율적인 배관작업 환경을 제공하는 단점이 있다.However, the conventional coated steel pipe adopts a pipe joint method by an annular band, so that when the axial directions between the main bodies do not coincide with each other, a poor coupling state is maintained, or it takes a lot of time to pipe the main bodies, There is a disadvantage of providing an inefficient piping work environment.

또한, 종래의 피복강관은 애뉼라밴드를 이용하기 때문에 플랜지 방식과 비교할 때, 내압 발생시 수밀성 유지가 어렵고, 비교적 강관들 간의 결합력이 약하기 때문에, 결합부위에 변형이 발생될 위험이 있다.In addition, since the conventional coated steel pipe uses an annular band, it is difficult to maintain watertightness when internal pressure is generated compared to the flange method, and since the bonding force between the steel pipes is relatively weak, there is a risk of deformation at the bonding site.

따라서, 근래 들어 양 끝단에 플랜지를 부착시킨 파형강관의 시제품이 개발되고 있으나, 이는 대구경을 갖는 본체의 외경에 플랜지를 수동으로 용접하여 부착하는 방법으로 제작되고 있으며, 따라서 대량 생산을 위한 설비의 부재로 인하여 제작 단가가 매우 높고, 이중 코팅된 고품질의 제품을 양산시킬 수 없는 문제점이 있다.Therefore, in recent years, a prototype of a corrugated steel pipe with flanges attached to both ends has been developed, but it is manufactured by manually welding and attaching a flange to the outer diameter of a body having a large diameter, and thus there is no equipment for mass production. Due to this, the manufacturing cost is very high, and there is a problem in that it is not possible to mass-produce a double-coated high-quality product.

특히, 종래의 파형강관은 플랜지를 본체에 용접하여 부착하기 때문에 용접 부위에 부식이 발생되기 쉬우며, 이는 건축용도 또는 토목용도로 사용되는 파형강관의 특성상 매우 큰 문제점으로 야기되고 있다.In particular, since the conventional corrugated steel pipe is attached by welding the flange to the body, corrosion is likely to occur at the welded portion, which is a very big problem due to the characteristics of the corrugated steel pipe used for construction or civil engineering purposes.

또한, 종래에는 파형강관에 피복을 한 피복강관의 제품들이 강관 제품으로 속속 출하되고 있으나, 이는 금속표면 또는 도금표면 위에 금속과 다른 재질의 수지가 피복되어 층(layer)을 형성하기 때문에, 소정 사용 시간이 경과한 피복강관의 경우, 수지층이 강관으로부터 이격되거나 박리되는 형상을 발생시킨다.In addition, conventionally, products of coated steel pipe coated with corrugated steel pipe are shipped one after another as steel pipe products. In the case of a coated steel pipe over time, a shape is generated in which the resin layer is separated from the steel pipe or peeled off.

특히, 종래의 피복파형강관은 다수의 나사골 또는 나사산에 의한 절곡 나선형 표면 형상을 갖기 때문에, 균일한 두께의 수지층을 외주표면에 형성하기 어렵거나, 피복 작업이 매우 번거럽고 대량 생산이 어려워 상대적으로 제조 단가가 고가인 단점이 있다.상기한 종래 기술들의 단점을 고려할 때, 가격과 생산성의 입장에서 대량 생산을 위한 설비의 개발이 시급한 실정인 것이다.In particular, since the conventional coated corrugated steel pipe has a curved helical surface shape by a number of threads or threads, it is difficult to form a resin layer of uniform thickness on the outer peripheral surface, or the coating operation is very cumbersome and mass production is difficult. There is a disadvantage in that the manufacturing cost is high. Considering the disadvantages of the prior art, it is urgent to develop a facility for mass production from the standpoint of price and productivity.

본 발명의 목적은 파형강관에 플랜지를 용접시공 한 후, 파형강관의 내, 외측 표면에 다중으로 수지 코팅층을 형성시키는 플랜지형 피복파형강관을 효율적이고 대량으로 생산할 수 있는 플랜지형 피복파형강관의 제조설비를 제공하려는 데 그 목적이 있다.It is an object of the present invention to manufacture a flange-type coated corrugated steel pipe that can efficiently and mass produce a flange-type coated corrugated steel pipe in which multiple resin coating layers are formed on the inner and outer surfaces of the corrugated steel pipe after the flange is welded to the corrugated steel pipe The purpose is to provide facilities.
