Description
본 발명은 압출하는 구조에 따라서 다양한 단면의 형상으로 연속 생산되는 합성수지물을 나선형으로 감으면서 회전시켜 보강성을 유지시키는 합성수지관을 성형함과 동시에 외부에 고강도 필름을 피복시켜 강도를 크게 향상시키도록 하는 강도가 향상된 합성수지관에 관한 것이다.The present invention is to form a synthetic resin tube to maintain the reinforcement by rotating while winding the synthetic resin continuously produced in a variety of cross-sectional shape according to the extrusion structure to at the same time to coat the high-strength film on the outside to greatly improve the strength It relates to a synthetic resin tube with improved strength.
합성수지관은 지중에 매설되어 배수관로의 용도로 사용되어 왔으며, 이러한 합성수지관은 콘크리트관이나 주철관에 비하여 가격이 저렴하고 경량이어서 취급 및 시공성이 우수한 장점을 가지고 있다.Synthetic resin pipes have been buried in the ground and used for drainage pipes. These synthetic pipes have the advantages of low cost and light weight compared to concrete pipes and cast iron pipes.
일반적인 합성수지관은 길이 방향을 따라 일정한 형상을 갖는 원료를 나선형으로 공급하면서 원형의 중공관을 성형하게 된다.In general, the synthetic resin tube is to form a circular hollow tube while spirally feeding the raw material having a certain shape along the longitudinal direction.
그러나 합성수지로만 이루어진 중공관은 하중강도가 약하여 토압이나 윤압에 매우 취약한 결점을 가지고 있다.However, hollow pipes made only of synthetic resins have a weak load strength and are very vulnerable to earth pressure and rotation pressure.
이러한 결점을 제거하기 위하여 실용신안공개번호 제95-30687호(1995. 11. 22)는 내부에 보강철심재를 삽입하여 외적인 하중이나 토압에 견딜 수 있도록 하는 장점을 제공하였다.In order to eliminate this drawback, Utility Model Publication No. 95-30687 (November 22, 1995) provided the advantage of being able to withstand external loads or earth pressure by inserting reinforcing iron cores therein.
그러나 보강철심재를 매설하여 단순 접합되어 있어서 큰 하중을 집중적으로 받게되면 수지층과 보강철심재가 쉽게 분리되어 변형되거나 파손되어 수명을 단축시키는 원인이 된다.However, when the reinforcing iron core is buried and simply joined to receive a large load, the resin layer and the reinforcing iron core are easily separated and deformed or broken, which causes a shortening of life.
또한 합성수지로만 구성되는 합성수지관은 도 1 과 같이 내부에 중공(31)이 형성된 사각관(30)을 나선형으로 연결시킨 합성수지관(10)을 제공하게 되나 강도가 떨어져 사용이 어려운 관계로 보강을 하기 위해서는 두께가 두꺼워져 재료의 손실이 많이 발생하는 결점이 있으므로 다양한 형태의 구조를 제공하여 강도를 향상시키거나 보강하는데는 한계가 있다.In addition, the synthetic resin tube consisting of only synthetic resin to provide a synthetic resin tube (10) spirally connected to the square tube 30, the hollow 31 is formed therein as shown in FIG. In order to improve the strength or reinforcement by providing various types of structures, there is a drawback in that a loss of material is caused due to a thick thickness.
본 발명은 합성수지 압출물이 일정한 형태의 보강부재로 제공되기 위하여 연속적으로 생산될 때 임의의 직경을 갖도록 나선형으로 회전함과 동시에 보강부재의 사이에 또 다른 합성수지 압출물을 공급하여 합성수지관을 제조함에 있어서, 합성수지 압출물의 형태를 통하여 강도를 향상시키도록 하는 것이다.The present invention is to manufacture a synthetic resin pipe by supplying another synthetic resin extrudates between the reinforcing member and at the same time to rotate in a spiral to have an arbitrary diameter when the synthetic resin extrudate is continuously produced to provide a reinforcement member of a certain form In order to improve the strength through the form of the synthetic resin extrudate.
본 발명은 나선형의 합성수지관을 성형시키는 과정에서 합성수지관의 외주연에 고강도 필름을 피복시켜 합성수지 압출물간의 결합력과 합성수지관의 강도를 크게 향상시키도록 하는 것이다.The present invention is to coat the high-strength film on the outer periphery of the synthetic resin tube in the process of forming the spiral synthetic resin tube to greatly improve the bonding strength between the synthetic resin extrudate and the strength of the synthetic resin tube.
본 발명은 합성수지 압출기를 통하여 내부에 중공이 형성된 보강부재를 공급함과 동시에 합성수지 압출기에서 연결부재를 나선형으로 연결시켜 합성수지관을 제조함에 있어서,The present invention provides a synthetic resin pipe by spirally connecting the connecting member in the synthetic resin extruder while supplying a reinforcing member having a hollow formed therein through the synthetic resin extruder,
상기 보강부재와 연결부재를 성형기에서 나선형으로 연결시켜 합성수지관을 성형하는 합성수지관의 성형과정 후 5∼10cm의 폭을 갖는 고강도 필름을 겹치게 공급하면서 외주연에 일체형으로 융착되도록 함을 특징으로 한다.The reinforcing member and the connecting member are helically connected to the outer periphery while supplying a high-strength film having a width of 5 to 10 cm after the forming process of the synthetic resin tube forming a synthetic resin tube by spirally connecting the molding machine.

본 발명은 비닐하우스에서 수거된 비닐이나 여러가지 경로를 통하여 수거된 합성수지를 파쇄한 재생원료공급(2) 과정에서 재생원료가 공급되면 합성수지 압출기(4)를 통하여 소정의 두께, 폭과 넓이를 통하여 일정한 형태의 보강부재(9)를 균일하게 공급하는 것이다.In the present invention, when the recycled raw material is supplied in the process of supplying the recycled raw material (2) which is crushed from the vinyl collected in the plastic house or the synthetic resin collected through various paths, the synthetic resin is extruded through a predetermined thickness, width, and width through the extruder (4). It is to uniformly supply the reinforcing member 9 of the form.
또한 재생원료가 아닌 정상적인 원료가 원료공급(3) 과정에서 공급되면 합성수지 압출기(5)를 통하여 연결부재(12)가 공급되는 것이다.In addition, when the normal raw material, not the recycled raw material, is supplied in the raw material supply 3 process, the connecting member 12 is supplied through the synthetic resin extruder 5.
합성수지 압출기(4)에서는 보강부재(9)가 연속적으로 균일하게 공급되어 성형기(6)에서 나선형으로 감기는 공급과정에서 합성수지 압출기(5)로부터 공급되는 연결부재(12)가 성형기(6)에 공급되어 보강부재(9)의 일측으로 연결부재(12)가 공급되는 것이다.In the synthetic resin extruder 4, the connecting member 12 supplied from the synthetic resin extruder 5 is supplied to the molding machine 6 in the feeding process in which the reinforcing member 9 is continuously uniformly supplied and spirally wound in the molding machine 6. The connection member 12 is supplied to one side of the reinforcement member 9.
즉, 성형기(6)에 공급되는 보강부재(9)는 나선형으로 감기면서 일측으로 공급되는 연결부재(12)와 함께 내,외측이 로울러로 압축되면서 이송되는 과정을 통하여 원형의 합성수지관(10)이 성형되는 것이다.That is, the reinforcing member 9 supplied to the molding machine 6 is circular synthetic resin tube 10 through a process in which the inside and the outside are compressed and transported together with the connecting member 12 supplied to one side while being spirally wound. This is to be molded.
보강부재(9)는 재생원료이므로 접착성이 약하나 연결부재(12)는 접착성이 강한 재료이므로 보강부재(9)를 안정되고 견고하게 연결시켜 결합력을 향상시키는 것이다.Since the reinforcing member 9 is a regenerated raw material, the adhesiveness is weak, but the connecting member 12 is a strong adhesive material, so that the reinforcing member 9 is stably and firmly connected to improve the bonding force.
이때 보강부재(9)와 연결부재(12)의 내,외측은 라운드부(13)를 크게 형성시켜 접촉단면적을 크게 하여 결합력을 더욱 향상시키는 것이다.At this time, the inner and outer sides of the reinforcing member 9 and the connecting member 12 to form a large round portion 13 to increase the contact cross-sectional area to further improve the bonding force.

The high-strength film 11 is spirally supplied while covering the outer side of the synthetic resin tube 1, but a portion of the high-strength film 11 overlaps and is pressed while applying pressure to the roller from the outside to reinforce the member (7). 9) and the outer periphery of the connecting member 12 is welded integrally to form a finished product (8).
고강도 필름(11)은 합성수지관(1)의 외부에 피복되어 외부물체와의 충돌로 인한 파손과 찍힘을 방지하고, 외부의 압력을 견디며 사계절 동안 온도의 변화에 따른 수축과 팽창을 방지하여 온도변화로 인하여 발생되는 누수 및 시트로 전기융착방법에 의하여 연결되는 연결부분의 손상을 방지하는 것이다.The high-strength film 11 is coated on the outside of the synthetic resin tube 1 to prevent breakage and chipping due to collision with an external object, to withstand external pressure, and to prevent shrinkage and expansion due to temperature change during the four seasons, thereby changing the temperature. It is to prevent the damage of the connecting portion connected by the electrofusion method to the leak and sheets generated by.
