Description

유리섬유 복합관{GLASS FIBER REINFORCED PLASTIC PIPE}Glass fiber composite pipe {GLASS FIBER REINFORCED PLASTIC PIPE}

본 발명은 유리섬유 복합관에 관한 것으로, 더욱 상세하게는 내부에 보강판이 유리섬유를 사이에 두고 순차적으로 적층됨에 따라 외부 충격에 매우 강하며, 내부에 고압력을 견디는 힘을 강화시킨 소구경을 포함하여 대구경도 손쉽게 제작할 수 있도록 한 유리섬유 복합관에 관한 것이다.The present invention relates to a glass fiber composite pipe, and more particularly, the reinforcement plate is laminated to the glass fiber in between, and thus is very resistant to external impact, including a small diameter reinforced strength to withstand high pressure therein The present invention relates to a glass fiber composite tube that enables easy manufacture of large diameters.

종래에 사용되는 상하수도 배관으로는 강관이나 주철관이 있으나 최대의 단점은 부식이 매우 심하고, 매우 무겁다는 점이다. 더욱이 상기 주철관의 경우에는 충격에 매우 약하다는 단점도 있다.Water and sewage pipes conventionally used include a steel pipe or a cast iron pipe, but the biggest disadvantage is that the corrosion is very severe and very heavy. Moreover, in the case of the cast iron pipe, there is a disadvantage that it is very weak to impact.

지하에 매설된 상수도관이 부식되거나 충격에 의해 균열이 발생할 경우, 누수에 의해 막대한 재정적 손실을 가져옴은 물론 외부 오염 물질 유입이나 내부 부식부위에 발생한 오염 물질에 의해 수질이 악화되는 결과를 초래한다. 상기와 같은 부식을 방지하기 위하여 강관에 에폭시를 도포하여 사용하기도 하고, 주철관에는 아스팔트나 콘크리트를 코팅하여 사용하기도 한다.If the underground water pipes are corroded or cracked due to impacts, they can lead to huge financial losses due to leakages, as well as the deterioration of water quality due to the inflow of external pollutants or contaminants generated at internal corrosion sites. In order to prevent the corrosion as described above may be used by applying epoxy to steel pipe, cast iron pipe may be used by coating asphalt or concrete.

이 경우, 도포된 에폭시나 아스팔트, 콘크리트 등이 쉽게 파손되고 벗겨지므로 여전히 부식의 위험성을 안고 있으며, 또한 코팅에 의해 생산비용이 증대함으로 써 일반적인 사용에 제약 요인이 되고 있다. 상하수도용 배관의 경우, 지하매설용으로 사용되는 경우가 많으므로 더욱 문제가 된다.In this case, since the coated epoxy, asphalt, concrete, etc. are easily broken and peeled off, there is still a risk of corrosion, and the production cost is increased by coating, which is a limiting factor for general use. Water and sewage piping is more problematic because it is often used for underground laying.

상기의 에폭시나 아스팔트, 콘크리트 등의 도포제는 단순히 부식을 방지하기 위한 코팅제에 불과하므로 코팅을 하더라도 강관이나 주철관의 두께를 감소시킬 수 없다. 따라서 무거운 중량에 의해 작업성과 운반성이 나쁘다는 단점이 여전히 남아 있게 된다.The coating agent such as epoxy, asphalt, concrete, etc. is merely a coating agent for preventing corrosion, so even if the coating can not reduce the thickness of the steel pipe or cast iron pipe. Therefore, the disadvantage of poor workability and transportability by heavy weight still remains.

한편, 부식 문제를 해결하기 위하여 합성수지관이 사용되기도 한다. 그러나 합성수지관은 내식성은 우수하지만 내압성이 매우 작음에 따라 관경이 클 경우 더욱 문제가 되고 있다. 중대형관은 지하 매설용으로 많이 사용되는데 내압성이 떨어질 경우, 관을 매우 두껍게 제작하여야 함에 따라 중량이 무거워지고 제작비용은 매우 높아지게 되는 단점이 있다.On the other hand, synthetic resin pipes are also used to solve the corrosion problem. However, synthetic resin pipes are excellent in corrosion resistance, but the pressure resistance is very small, which is more problematic when the diameter is large. Medium and large size pipes are often used for underground burial, but if the pressure resistance is low, the pipes have to be made very thick, which results in heavy weight and very high manufacturing costs.

이에 합성수지관의 취약점인 내압성을 해결하기 위하여 합성수지관의 제조시 수지 내부에 부분적으로 금속편을 삽입하는 방법이 도입되었다.In order to solve the pressure resistance, which is a weak point of the synthetic resin pipe, a method of partially inserting a metal piece into the resin was introduced during the production of the synthetic resin pipe.

그러나 이 경우 내압성이 어느정도는 향상될 수는 있으나 대형관에서 요구되는 정도로 대폭 향상되지는 않으며, 특히 합성수지만으로 된 부분은 충격에 매우 약하여 외부에서 큰 충격이 가해지면 파손될 가능성이 많은 단점을 안고 있다.However, in this case, although the pressure resistance may be improved to some extent, it is not significantly improved as required in a large pipe. Particularly, the part made of synthetic resin is very weak to impact, and thus has a lot of damage that can be damaged when a large impact is applied from the outside.

본 발명은 상기한 문제점을 해결하기 위하여 창안된 것으로, 본 발명의 목적은 부식이 발생하지 않고, 무게가 금속관 만큼 무겁지 않으면서도 내압성 또한 뛰어나 소구경 관 뿐만 아니라 대형관까지도 제작할 수 있으며, 특히 내부에 보강판이 유리섬유를 사이에 두고 순차적으로 적층된 상태로 이루어짐에 따라 외부 충격에 매우 강하며, 이에 따라 수명연장으로 설치 후 장기간 사용이 가능한 유리섬유 복합관을 제공함에 있다.The present invention was devised to solve the above problems, and the object of the present invention is that corrosion does not occur, the weight is not as heavy as a metal tube, but also excellent in pressure resistance, so that not only a small diameter tube but also a large tube can be manufactured. As the reinforcing plate is made in a state of being laminated sequentially with glass fibers in between, it is very resistant to external shocks, and thus provides a glass fiber composite tube that can be used for a long time after installation as an extension of life.

이하, 첨부된 도면을 참조하여 본 발명의 유리섬유 복합관을 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a glass fiber composite tube of the present invention.

도 1은 본 발명에 의한 유리섬유 복합관의 단면을 보인 상태도이고, 도 2는 본 발명에 의한 롤링방식으로 회전되는 보강판을 보인 상태도이며, 도 3은 본 발명에 의한 개별 링으로 구비되는 보강판을 보인 상태도이다.1 is a state diagram showing a cross-section of the glass fiber composite tube according to the present invention, Figure 2 is a state diagram showing a reinforcing plate rotated by a rolling method according to the present invention, Figure 3 is a reinforcing plate provided with an individual ring according to the present invention Is a state diagram.

상기 도면에 도시된 바와 같이, 본 발명에 의한 유리섬유 복합관은 관의 내부식성 및 내마모성을 향상시키기 위해 유리섬유로 강화시킨 것으로서, 상기 복합수지가 첨가된 유리섬유(15)를 감싸도록 보강판(20)이 구비되고, 상기 보강판(20)의 외부에 다른 복합수지가 첨가된 유리섬유(15)가 감싸여져 이루어진다.As shown in the figure, the glass fiber composite tube according to the present invention is reinforced with glass fiber to improve the corrosion resistance and abrasion resistance of the tube, the reinforcement plate to surround the glass fiber (15) to which the composite resin is added ( 20) is provided, and is made of the glass fiber 15, the other composite resin is added to the outside of the reinforcing plate 20 is wrapped.

다시 말해, 일정 관경을 갖는 수지관(10)의 외표면에 수지관(10)을 감싸도록 복합수지가 첨가된 유리섬유(15)가 적층되고, 상기 복합수지가 첨가된 유리섬유(15)의 외표면에 복합수지가 첨가된 유리섬유(15)를 감싸도록 보강판(20)이 적층되며, 상기 보강판(20)의 외표면으로 상기 복합수지가 첨가된 유리섬유(15)와 보강판(20)이 순차적으로 다수 적층되어 이루어지게 된다.In other words, the glass fiber 15 to which the composite resin is added is laminated on the outer surface of the resin tube 10 having a predetermined diameter so as to surround the resin tube 10, and the composite of the glass fiber 15 to which the composite resin is added is laminated. The reinforcing plate 20 is laminated to surround the glass fiber 15 to which the composite resin is added to the outer surface, and the glass fiber 15 and the reinforcing plate to which the composite resin is added to the outer surface of the reinforcing plate 20 ( 20) is made of a plurality of sequentially stacked.

이는 도 1에서와 같이 상기 수지관(10)의 외부에 제1유리섬유(16)가 감싸여지고, 제1유리섬유(16)의 외부에 제1보강판(21)이 감싸여지며, 상기 제1보강판(21)의 외부에 제2유리섬유(17)와 제2보강판(22)과 제3유리섬유(18) 및 제3보강판(23)이 순차적으로 적층되어 복합관을 이루게 되며, 상기 유리섬유와 보강판은 관경에 따라 그 갯수를 달리하면 된다.As shown in FIG. 1, the first glass fiber 16 is wrapped around the outside of the resin tube 10, and the first reinforcing plate 21 is wrapped around the outside of the first glass fiber 16. On the outside of the first reinforcing plate 21, the second glass fiber 17, the second reinforcing plate 22, the third glass fiber 18 and the third reinforcing plate 23 are sequentially stacked to form a composite pipe. The number of glass fibers and reinforcement plates may vary depending on the diameter.

여기서, 상기 수지관(10)은 기계적 강도를 향상시키기 위해 복합수지에 유리섬유를 혼합하여 경화시킨 유리섬유복합관이고, 상기 보강판(20)에는 보강판(20)을 기준으로 안쪽과 바깥쪽에 적층되는 복합수지가 서로 연통하도록 일정 간격으로 통공(25)이 타공되어 형성된 것이 바람직하다.Here, the resin tube 10 is a glass fiber composite tube cured by mixing the glass fiber in the composite resin to improve the mechanical strength, the reinforcement plate 20 is laminated on the inside and the outside based on the reinforcement plate 20 It is preferable that the through holes 25 are formed at a predetermined interval so that the compound resins communicate with each other.

따라서, 상기 통공(25)을 통해 복합수지가 통과된 상태로 복합관이 완성됨에 따라 복합수지가 첨가된 유리섬유(15)와 보강판(20)이 서로 박리되지 않을 뿐만 아 니라 더욱 견고하게 접합되어 내구성이 향상되어 지게 된다.Therefore, as the composite tube is completed while the composite resin is passed through the through hole 25, the glass fiber 15 and the reinforcing plate 20 to which the composite resin is added are not peeled from each other, but more firmly bonded together. Durability is improved.

여기서, 본 발명의 상기 보강판(20)은 관성형기에 의해 회전되면서 상기 복합수지가 첨가된 유리섬유(15)의 일측 외표면에서 타측 외표면으로 감겨져 감싸여지는 철판인 것이 바람직하다. 이때 상기 철판은 상기 복합수지가 첨가된 유리섬유(15)를 사이에 두고 적층되는 경우 철판과 철판의 사이로의 압력차이를 방지하기 위해 도 1에서와 같이 서로 지그재그형으로 적층되게 한다.Here, the reinforcing plate 20 of the present invention is preferably an iron plate which is wound around the outer surface of the outer surface of one side of the glass fiber 15 to which the composite resin is added while being rotated by an inertial molding machine. In this case, the iron plates are stacked in a zigzag shape as shown in FIG. 1 in order to prevent a pressure difference between the iron plate and the iron plate when the composite resin is laminated with the glass fiber 15 added therebetween.

또한, 다른 실시예로서 상기 보강판(20)은 일정 폭을 갖는 고리형의 개별링으로서, 상기 복합수지가 첨가된 유리섬유(15)의 외표면에 다수개 결속되게 하여 상기 복합수지가 첨가된 유리섬유(15)를 감싸도록 할 수 있다.In another embodiment, the reinforcing plate 20 is a ring-shaped individual ring having a predetermined width, and the composite resin is added to bind to the outer surface of the glass fiber 15 to which the composite resin is added. It can be wrapped around the glass fiber (15).

이 경우에도 상기 보강판(20)은 상기 복합수지가 첨가된 유리섬유(15)를 사이에 두고 적층되면서 발생될 수 있는 압력차이를 미연에 방지하도록 도 1에서와 서로 지그재그형으로 적층되게 한다.Even in this case, the reinforcing plate 20 is laminated in a zigzag shape with each other in FIG. 1 so as to prevent a pressure difference that may occur while being laminated with the glass fiber 15 to which the composite resin is added.

또한, 상기 보강판(20)을 개별 링으로 형성하는 경우 상기한 바와 같이 지그재그형으로 적층시키지 않고, 최하측 보강판과 동일하게 적층시킬 수 있으며, 상기 복합수지가 첨가된 유리섬유(15)를 사이에 두고 결합되는 경우 양측 주연부가 서로 간섭되도록 밀착결합되게 한다.In addition, when the reinforcing plate 20 is formed as an individual ring, it may be laminated in the same manner as the lowermost reinforcing plate without being stacked in a zigzag shape as described above, and the glass fiber 15 to which the composite resin is added may be laminated. When coupled in between, the two peripheral edges are to be closely coupled so as to interfere with each other.

한편, 또 다른 실시예로서 상기 보강판(20)은 일정 직경을 갖는 철선으로, 상기 복합수지가 첨가된 유리섬유(15)의 외표면에 체크무늬형으로 직조되게 얽혀지게 하여 구비할 수 있다.Meanwhile, as another embodiment, the reinforcing plate 20 may be provided as an iron wire having a predetermined diameter and woven in a checkered pattern on the outer surface of the glass fiber 15 to which the composite resin is added.

이때, 상기 철선은 짜여지면서 구멍이 형성됨에 따라 그 사이로 유리섬유에 혼합된 상기 복합수지가 통과하게 된다.At this time, as the iron wire is woven, the composite resin mixed with the glass fiber passes through the hole.

상기와 같이 구성된 본 발명의 작용 및 효과를 도 1을 참조하여 살펴보면, 제작하고자 하는 구경의 수지관(10)을 제조한 후 상기 수지관(10)의 외부를 제1유리섬유(16)로 감싸고, 제1유리섬유(16)의 외부를 제1보강판(21)으로 감싼다. 그리고 나서 순차적으로 제2유리섬유(17)와 제2보강판(22)과 제3유리섬유(18)과 제3보강판(23)을 적층시켜 복합관을 형성하면 된다.Looking at the operation and effect of the present invention configured as described above with reference to Figure 1, after producing the resin tube 10 of the diameter to be manufactured, the outer surface of the resin tube 10 is wrapped with a first glass fiber 16 The outer surface of the first glass fiber 16 is wrapped with the first reinforcing plate 21. Then, the second glass fiber 17, the second reinforcing plate 22, the third glass fiber 18 and the third reinforcing plate 23 may be sequentially laminated to form a composite pipe.

이때, 상기한 각각의 보강판은 통상 벽돌을 적층시키는 방식과 같이 서로 지그재그형식으로 적층되게 하며, 이러한 적층방식에 따라 설치 후 압력차이를 방지할 수 있게 된다.At this time, each of the reinforcement plate is to be laminated in a zigzag form with each other, such as a method of stacking the usual brick, it is possible to prevent the pressure difference after installation in accordance with this stacking method.

또한, 상기 각각의 보강판에는 통공(25)이 형성되어 있어 상기 통공(25)을 통해 각층에 구비되는 복합수지가 서로 연통됨에 따라 박리되지 않은 상태로 더욱 견고하게 일체로 접합되면서 복합관이 형성되어 지게 된다.In addition, each of the reinforcing plate is formed with a through-hole 25, the composite resin is provided in each layer through the through-hole 25 is in communication with each other, the composite pipe is formed while more integrally bonded without being peeled off You lose.

따라서, 설치 후 외부압력이 작용하더라도 손쉽게 파손되지 않을 뿐만 아니라 대구경인 경우에도 유리섬유와 보강판의 박리를 방지하며, 내구성을 높인 상태로 제작할 수 있게 된다.Therefore, even if the external pressure is applied after installation, not only is not easily damaged, but also prevents peeling of the glass fiber and the reinforcement plate even in the case of large diameter, it is possible to manufacture in a state of high durability.
