본 발명은 합성수지관의 이중 삼각형 보강구조 및 그 제조방법에 관한 것으로, 더욱 상세하게는 중앙에 세로 방향으로 중앙 보강대가 설치된 삼각 보강대를 일체형으로 성형한 후 삼각 보강대의 외측을 이종재질로 코팅한 피복 부재를 프로파일의 중공에 공급하여 프로파일과 일체형으로 성형함으로써 강도를 크게 향상시키도록 하는 합성수지관의 이중 삼각형 보강구조 및 그 제조방법에 관한 것이다.The present invention relates to a double triangular reinforcement structure of a synthetic resin pipe and a method of manufacturing the same, and more particularly, after forming a triangular reinforcement unit having a central reinforcement in the longitudinal direction at the center integrally formed coating the outer side of the triangular reinforcement coated with a dissimilar material The present invention relates to a double triangular reinforcement structure of a synthetic resin tube and a method of manufacturing the same, in which a member is supplied to the hollow of a profile to be molded integrally with the profile to greatly improve strength.

종래 이중벽 하수관은 사각형의 프로파일로 형성되며 내부에 사각형의 중공이 형성되어 압출된 후 냉각과정을 거쳐 와인딩 장치에 나선형으로 공급될 때 프로파일의 사이에 연결부재가 공급되어 원통형으로 성형 된다.The conventional double wall sewer pipe is formed into a rectangular profile, and when the hollow inside is formed to be extruded and extruded and then spirally supplied to the winding device through a cooling process, the connecting member is supplied between the profiles to be formed into a cylindrical shape.

그리고 복층벽 하수관은 사각형의 프로파일 내부에 형성되는 사각형의 중공에 열십자 형태로 보강대를 일체형으로 성형하면서 압출된 후 냉각과정을 거쳐 와인딩 장치에 나선형으로 공급될 때 프로파일의 사이에 연결부재가 공급되어 원통형으로 성형 된다.And the multi-layered sewer pipe is extruded while integrally forming the reinforcing rod in the form of a cross in a hollow hollow formed inside the rectangular profile, and then connected to the member when the spiral is supplied to the winding device through the cooling process. It is molded into a cylinder.

그러나 상기에서 설명한 이중벽 하수관과 복층벽 하수관은 모두 동일한 재질로 성형하는 것이어서 성형한 후에 강도가 낮아 토압이 많아 발생하거나 낮은 깊이에 설치하는 경우, 그리고 하중이 크게 발생하는 장소에 설치하는 경우 하중에 의 해서 연결부재 주변에서 끊기거나 분리 및 관의 형상이 변형되어 결국에는 파손되는 결점이 발생한다.However, the double wall sewer pipe and the double wall sewer pipe described above are all molded with the same material, so that the strength is low after molding, so that the earth pressure is high due to low earth pressure, or when it is installed at a low depth, and when it is installed in a place where a large load occurs. This results in breakage around the connecting member or deformation and separation of the tube and eventually breakage.

또한, 복층벽 하수관의 경우에는 내부에 열십자형으로 보강대를 성형하게 되므로 쉽게 냉각되지 않아서 냉각시간의 소모가 많아 생산성이 저하되며, 원료의 소모가 많아 원료의 소모에 비하여 하중의 향상이 이루어지지 못하는 결점이 있었다.In addition, in the case of the double-walled sewer pipe, since the reinforcing rod is formed inside the crosshairs, it is not easily cooled and thus the cooling time is increased, thus the productivity is lowered. As the consumption of the raw material is high, the load cannot be improved compared to the consumption of the raw material. There was a flaw.

본 발명은 이러한 종래의 결점을 해소하기 위하여 안출된 것으로, 삼각 보강대의 중앙으로 세로 방향에 중앙 보강대를 형성하여 보강하고 삼각 보강대의 전체면을 다른 재질(P.P)로 코팅하여 강도를 부여한 후 프로파일의 중공에 삼각 보강대를 삽입하여 합성수지관을 성형함으로써 강도를 크게 향상시키도록 함을 목적으로 한다.The present invention has been devised to solve such a conventional drawback, the center of the triangular reinforcement to form a reinforcement in the longitudinal direction to the center of the reinforcement, and the entire surface of the triangular reinforcement coated with a different material (PP) to impart strength and then It is intended to greatly improve the strength by inserting a triangular reinforcement in the hollow to form a synthetic resin tube.

이러한 목적으로 이루어진 본 발명을 바람직한 실시예를 통하여 상세하게 설명하기로 한다.The present invention made for this purpose will be described in detail through preferred embodiments.

도 2 와 같이 중앙의 세로 방향에 중앙 보강대(64)를 세우고 그 양측에 삼각형의 공간(65)을 갖는 삼각 보강대(63)가 삼각 보강대 압출기(10)에서 공급하는 합성수지(P.E)에 의해 압출 노즐(11)을 통과하면서 일체형으로 성형한다.As shown in FIG. 2, an extrusion nozzle is formed by a synthetic resin (PE) supplied from a triangular reinforcing rod extruder 10 by a triangular reinforcing rod 63 having a central reinforcing rod 64 in a vertical longitudinal direction and having triangular spaces 65 on both sides thereof. Molded in one piece while passing through (11).

압출 노즐(11)을 통과하면서 성형한 삼각 보강대(63)는 전방의 냉각기(12)를 통과하면서 냉각이 이루어지며 전방의 피복 노즐(21)을 통과하면서 피복 압출기(20)에서 공급하는 다른 재질(P.P)에 의해 외부의 전체면에서 피복 부재(66)가 얇게 코팅이 이루어진다.The triangular reinforcement 63 formed while passing through the extrusion nozzle 11 is cooled while passing through the cooler 12 in front of the other material supplied from the coated extruder 20 while passing through the front coating nozzle 21 ( The coating member 66 is thinly coated on the entire outer surface by PP).

상기 피복 부재(66)는 삼각 보강대(63)의 재질이 P.E인 경우 강도가 더 높은 P.P를 사용하는 것이 바람직하다.The covering member 66 is preferably P.P having a higher strength when the material of the triangular reinforcement 63 is P.E.

삼갈 보강대(63)의 외측 전체면을 피복 부재(66)로 코팅한 후 프로파일 노즐(31)에 공급하여 프로파일 압출기(30)에서 공급하는 합성수지가 중공(62)에 피복 부재(66)가 위치하도록 프로파일(61)을 압출하는 것이다.After coating the entire outer surface of the samba reinforcement 63 with the coating member 66, the synthetic resin supplied from the profile extruder 30 to supply to the profile nozzle 31 so that the coating member 66 is located in the hollow 62. The profile 61 is extruded.

상기 냉각기(12)는 필요에 따라서 피복 노즐(21)의 전방이나 프로파일 노즐(31)의 전방에도 설치할 수 있는 것이다.The said cooler 12 can also be provided in front of the coating nozzle 21 and the front of the profile nozzle 31 as needed.

삼각 보강대(63)와 피복 부재(66)가 중공(62)에 일체형으로 성형 된 프로파일(61)은 와인딩 장치(40)의 드럼에 나선형으로 연속해서 공급이 이루어진다.The profile 61 in which the triangular reinforcement 63 and the covering member 66 are integrally formed in the hollow 62 is continuously supplied to the drum of the winding device 40 in a spiral manner.

와인딩 장치(40)에 프로파일(61)이 나선형으로 공급될 때 연결부재 압출기(50)에서 프로파일(61)과 동일한 재질의 합성수지가 용융되어 프로파일(61)의 사이에 연결부재(67)로 공급되어 합성수지관(60)을 성형한다.When the profile 61 is spirally supplied to the winding device 40, the synthetic resin of the same material as the profile 61 is melted in the connecting member extruder 50 and supplied to the connecting member 67 between the profiles 61. The synthetic resin tube 60 is molded.

합성수지관(60)이 연속해서 성형되면 전방의 절단장치(70)에서 일정한 길이(약 6m)로 절단하여 배출한다.When the synthetic resin tube 60 is continuously molded, the cutting device 70 is cut into a predetermined length (about 6 m) and discharged from the front cutting device 70.

상기 프로파일(61)은 사각형으로 성형하는 것을 보통으로 하며, 내부의 중공(62)에 삼각 보강대(63)를 피복 부재(66)로 코팅하여 일체형으로 성형하는 것이며, 프로파일(61)의 사이에는 연결부재(67)가 공급되어 평활한 합성수지관(60)을 성형한다.The profile 61 is usually formed in a rectangular shape, and is formed by coating a triangular reinforcement 63 with a covering member 66 on the inner hollow 62 to be integrally formed and connected between the profiles 61. The member 67 is supplied to shape the smooth synthetic resin tube 60.

상기 프로파일(61)은 내부에 중공(62)이 성형 되도록 압출하는 것이지만, 도 7 에 도시한 바와 같이 피복부재(66)의 외측에 중공(62)이 없이 전체면을 채워서 일체형으로 성형하는 채움 프로파일(70)을 성형하는 것도 가능하며, 이러한 기술내용은 본 발명의 기술범주에 속하는 것이다.The profile 61 is extruded so that the hollow 62 is molded therein, but as shown in FIG. 7, the filling profile is formed integrally by filling the entire surface without the hollow 62 outside the coating member 66. It is also possible to mold 70, and this description belongs to the technical category of the present invention.

이러한 구성으로 이루어진 본 발명의 실시예를 상세하게 설명하기로 한다.An embodiment of the present invention having such a configuration will be described in detail.
