본 고안은 새로운 단면 구성의 합성수지제 2중나선관에 관한 것이다.The present invention relates to a synthetic double helix tube of a new cross-sectional configuration.

더욱 상세하게 설명하면 본 고안은 합성수지나선관의 관체를 내벽과 외벽의 2중이 되게함과 동시에 내, 외벽 사이에 중공부와 격벽을 형성하도록 구성한 2중나선관에 있어서 내압성을 보다 증대시킴으로써 상, 하수도용을 비롯한 기타 각종 지하매설용 대경(大徑)관체로서 유효하게 사용할 수 있는 개량된 단면구조를 가진 합성수지제 2중 나선관을 제공함을 목적으로 한 것이다.In more detail, the present invention makes the tubular body of the synthetic resin spiral tube double between the inner wall and the outer wall, and at the same time, further increases the pressure resistance in the double spiral tube configured to form the hollow portion and the partition wall between the inner and outer walls. An object of the present invention is to provide a synthetic resin double-stranded pipe having an improved cross-sectional structure that can be effectively used as a large diameter pipe for sewage and other various underground laying.

종래 하수도용 또는 농업(배수)용으로서 많이 사응되고 있는 2중관체는 예를들면 제1(a)도, 제2(a)도에 예시된 바와같이(일본실용신안출원공고번호 소 48-25214), 내외벽 사이에 형성된 격벽이 내, 외벽(a)(b)에 대하여 수직을 이루고 있어 관체에 수직으로 작용되는 외압에 대하여서는 강한 저항력을 나타낼수가 있으나 관체에 대하여 경사방향으로 작용되는 외력에 대하여서는 취약한 결함이 있었다.Conventionally, a double pipe that has been widely used for sewerage or agriculture (drainage) is, for example, as illustrated in Figs. 1 (a) and 2 (a) (Japanese Utility Model Application Publication No. 48-25214 ), The partition wall formed between the inner and outer walls is perpendicular to the inner and outer walls (a) and (b), so it can show strong resistance against external pressure acting perpendicularly to the tube. There was a weak flaw.

본 고안에서는 상기와 같은 문제점들을 해결하기 위하여 내, 외벽(a),(b)사이에 형성되는 격벽(1)을 단면형으로 연속 구성되도록 하였는바, 첨부된 도면에 의거하여 본 고안을 실시예에 따라서 상술하면 다음과 같다.In the present invention in order to solve the above problems, the partition wall (1) formed between the inner, outer walls (a), (b) cross section It was to be configured in a continuous bar, according to the present invention according to the embodiment based on the accompanying drawings as follows.

제1(a)도에서 종래관체는 내벽(a)와 외벽(b)로 구성되고 이들 내, 외벽(a),(b)사이에는 격벽(1)이 일정한 간격을 두고 내, 외벽(a),(b)에 대하여 거의 수직으로 입설되어 있고 이들 격벽(1)과 내, 외벽(a),(b)사이에는 중공부(2)가 형성되어 있다.In FIG. 1 (a), the conventional tubular body is composed of an inner wall (a) and an outer wall (b), and the partition wall (1) is spaced between the inner walls, the outer walls (a), and (b) at regular intervals. It is placed perpendicularly to (b), and the hollow part 2 is formed between these partition walls 1 and the inner side, outer wall a, and b.

이와같은 2중 관체는 예를들면 제2(a)도에 도시된 바와같이 좌, 우양측의 격벽(1')와 (1'')는 중앙격벽(1)을 경사방향으로 절단한 상태를 한 한단위의 합성수지 대상체(帶狀體)를 반연화상태에서 다이스로부터 압출하고, 이것을 회전권취봉 위에 나선상으로 권회하여 인접한 대상체의 연부(1')와 (1'') 또는 (1'')와 (1')가 서로 겹쳐져서 융착 일체화되도록하여 구성되는 것으로 관체에 대한 수직방향의 외압에는 강한 저항력을 나타낼 수 있으나, 관체에 대하여 경사방향으로 외력이 작용되면 수직격벽(1)이 절손될 취약점이 있다.For example, as shown in FIG. 2 (a), the double walls of the double tube have a state in which the central bulkhead 1 is cut in an inclined direction. One unit of synthetic resin is extruded from the die in a semi-softened state, and it is wound spirally on a rotary winding rod, so that the edges (1 ') and (1' ') or (1' ') of adjacent objects are wound. And (1 ') are overlapped with each other so as to be fusion-integrated and may exhibit a strong resistance to external pressure in the vertical direction to the tube, but when the external force is applied in an oblique direction to the tube, the vertical bulkhead (1) may be broken. There is this.

그러나 제1(b)도와 같은 본 고안의 경우는 제2(b)도와 같은 단위대상체를 상기와 같은 요령으로 나선상으로 권회하여 그 양단부가 겹쳐져서 용착일체화 되도록하여 구성되는 것으로, 관체에 대한 수직방향의 외압은 물론 경사방향에서 가하여지는 외력에 대하여서도 그 격벽(11)이 강하게 대항할수 있으므로 결국 관체에 가하여 지는 어떤 방향의 외력에 대하여서도 쉬이 파손되지 않고 오래 견딜 수 있는 효과를 나타내게 된다.However, in the present invention as shown in FIG. 1 (b), the unit object as shown in FIG. 2 (b) is wound in a spiral manner as described above, and both ends thereof are overlapped to form a single welded body. The partition 11 can be strongly opposed to the external force applied in the inclined direction as well as the external pressure, so that the external force in any direction applied to the tube can be easily sustained without breakage.

본 고안에서 사용되는 합성수지의 재질로서는 경질 내지 반경질의 PVC수지가 내구성, 내수성, 내약품성, 내후성, 내하중성, 관체연결작업성등면에서 바람직하다. 또 상기에서 반연화 상태라고 한것은 상접한 대상체의 연사가 서로 융착될 수 있는 정도의 가열된 상태이면서 동시에 소정의 형태를 유지할 수 있는 상태에 있을때를 말한다.As a material of the synthetic resin used in the present invention, hard to semi-rigid PVC resin is preferable in terms of durability, water resistance, chemical resistance, weather resistance, load resistance, pipe joint workability, and the like. In addition, the semi-softened state in the above refers to a state in which the yarns of the intimate objects are in a heated state such that they can be fused to each other while maintaining a predetermined form.

본 고안의 실시에 있어서 한단위의 대상체속에 몇개소의 격벽을 형성하느냐 하는 것은 관체의 구경의 크기나 용도등에 따라서 임의 선택 결정되어지나 제2(b)도에 예시한 경우가 기본적인 것으로 본다.In the practice of the present invention, how many partitions are formed in one unit of object is arbitrarily selected depending on the size and use of the diameter of the tube, but it is considered that the case illustrated in FIG.

또 제2(b)도에서 좌, 우측에서 융착되는 격벽의 합쳐진 폭은 반드시 중앙격벽의 폭과 동일하여야 하는 것은 아니며 경우에 따라서는 2배가 되게 할 수도 있으나, 이들의 폭을 동일하게 하는 경우가 기본적인 것으로 본다. 따라서 본 고안에 의한 합성수지제 2중나선관은 대구경 의하수도관, 상수도관, 기타 각종 배수관으로 사용하면 구경에 비하여 매우 경량이어서 운반하거나 작업상 취급하기 편리하고 그 재질상 쉬이 파손되지 않을뿐 아니라 연결잡업면에서도 신속 용이하게 실시할 수 있는 이점이 있고, 한꺼번에 길게 제조한 수 있어 작업성을 그만큼 향상시킬 수 있음과 동시에 그만큼 누수율을 감소시킬 수 있고, 2중으로 구성되어 있어 외벽이 파손되어도 내벽이 남아있어 내구적으로 사용될 수 있고 내외벽 사이에 중공부가 형성되어 있어 보온성이 좋은등 여러가지 이점을 나타낼 수가 있는 이외에도, 특히 본 고안에서는 내외벽(a)(b)사이에 형성되어 있는 격벽(11)이 경사방향으로 (단면형으로)연속형성되어 있어 관체에 가하여지는 외력의 방향에는 관계없이 항시 강력한 저항력을 나타낼수가 있어 격벽(11)이 외력에 의하여 절손될 우려가 거의 없는 이점을 나타낼 수가 있다.In FIG. 2 (b), the combined widths of the partition walls fused at the left and right sides are not necessarily the same as the width of the central partition wall, and may be doubled in some cases, but the widths thereof are the same. Seen as basic Therefore, the synthetic resin double helix tube according to the present invention is very light compared to the diameter when used as a large diameter sewage pipe, water pipe, and other various drainage pipes, which is convenient to carry or handle in operation, and does not break easily due to its material. In terms of advantages, it can be quickly and easily carried out, and it can be manufactured at a time for a long time, thereby improving workability and reducing the leak rate, and having a double structure, even if the outer wall is damaged, the inner wall remains. In addition to being able to be used internally and having a hollow portion formed between the inner and outer walls to exhibit various advantages such as good heat retention, in particular, in the present invention, the partition wall 11 formed between the inner and outer walls (a) and (b) is inclined. Direction (section Since it is continuously formed, it can exhibit a strong resistance at all times regardless of the direction of the external force applied to the tubular body, and can exhibit an advantage that the partition 11 is hardly damaged by the external force.
