본 고안은 도로의 지하 배수관 등과 같이 토압 또는 차량하중이 크게 작용하는데 사용되는 구조용 합성수지 파이프에 관한 것이다.The present invention relates to a structural synthetic resin pipe used to act largely on earth pressure or vehicle load, such as underground drainage pipes.

종래에도 구조적으로 큰하중에 견딜 수 있도록 하여주는 여러가지의 구조용 합성수지 파이프들이 사용되어 왔다. 그 중 하나는 그 단위체의 내부에 엔지니어링 플라스틱이나 강판등의 보강재를 매설시켜서 보다 큰 집중 하중에 견딜 수 있도록 하여주는 보강합성 수지 파이프가 최근에 알려져 사용되어 왔다. 이러한 보강 합성수지 파이프는 많은 힘을 받는 것은 사실이지만, 용착면부가 되는 단위체의 하부 용착살부분에는 보강재가 매설 못하였다.Conventionally, various structural synthetic pipes have been used to withstand structurally heavy loads. One of them has recently been known and used a reinforced synthetic resin pipe to embed a reinforcing material such as engineering plastics or steel sheet inside the unit to withstand a greater concentrated load. It is true that such a reinforced plastic pipe receives a lot of force, but a reinforcing material was not buried in the lower welding portion of the unit to be a welding surface portion.

따라서 이러한 용착살부분이 국부적으로 취약한 부분이 될 수밖에 없는데, 이는 다른 부분은 중공부를 사이에 두고 형성되는 상부 및 하부 플랜지가 웨브를 통하여 전달되는 하중을 공동으로 부담하게 되는데 비하여, 용작면부가 되는 하부 용착살부분은 날겹으로서 모든 하중을 부담해야 하기 때문이다. 이러한 구조상의 결함으로 인하여 이러한 종류의 합성수지 파이프는 항시 하부 용착살부분에서 파손되는 사례가 많이 발생하는 결함이 있었다.Therefore, the welded portion must be a locally weak portion, which is a lower portion that is the lower surface portion, while the other portion jointly bears the load transmitted through the web between the upper and lower flanges formed with the hollow portion interposed therebetween. This is because the weld strip must bear all the load as the blade. Due to such structural defects, this kind of synthetic pipe had a defect that a lot of cases are always broken in the lower welding portion.

예컨데, 단위체사이에 보강편을 접착한 합성수지재 나선 보강 파이프(실용신안공고번호 제88-3531호)는 지층에 뭍힌 상태에서 심한 하중을 받게 되면 이 접착 부위가 파이프체의 단위체로부터 떨어지거나 찢기는 폐단이 있어 접합부위의 보강력과 안정성이 저하되는 결함이 있었다.For example, a synthetic resin spiral reinforcing pipe (Utility Model No. 88-3531), which has a reinforcing piece bonded between units, is a closed end where the adhesive site falls or tears from the unit of the pipe body when subjected to heavy loads in the state of being laid in the ground. There was a defect that the reinforcement and stability of the joint is reduced.

이러한 결함을 해소하고자 선출원(실용신안공고번호 제91-8118호)한 합성수지재 나선 보강 파이프는, 크기가 상호 다른 대, 소단위체를 교호로 반복되게 나선방향으로 권회시킨 뒤 그 대단위체 또는 소단위체의 중공부내의 지그재그로 절곡된 파형의 보강대를 나선방향으로 삽입하여 각 단위체에 보강대의 상, 하측단을 매설하여 일체화하여 구성하였으나, 이 보강대는 첫째, 상기 보강대는 파형으로 형성되어 있어 절곡된 한 단면을 보면 그 자체로는 토압에 충분히 견딜 수가 있겠으나 토압이 파이프의 원주방향에서 중심방향으로 집중 작용하게 될 때 지그재그로 절곡된 파형이 변형되기 때문에 강력한 강도를 유지하지 못하는 폐단이 있으며, 둘째, 보강대를 파형으로 제작하는데 있어 매우 까다로워 작업상의 비용이성으로 인한 생산단가가 높게 설정되는 비경제적인 폐단이 있었다.The synthetic resin spiral reinforcing pipe, which has been filed earlier (Utility Model Publication No. 91-8118) to solve such defects, is wound in a spiral direction in which the subunits of different sizes are alternately repeated. The reinforcing bar of the corrugated bent by zigzag in the hollow part of the hollow part was inserted in the helical direction, and the upper and lower ends of the reinforcing bar were embedded in each unit to be integrated, but the reinforcing bar was first formed in a corrugated form. The cross section can withstand the earth pressure by itself, but when the earth pressure is concentrated in the circumferential direction of the pipe, the zigzag bent wave is deformed, so there is a closed end that cannot maintain strong strength. It is very difficult to fabricate the reinforcement with wave shape, so the production cost is high due to the cost-effectiveness of operation. Which had a non-economic evils.

따라서, 본 고안의 목적은 단면상 사각형으로 형성되게 나선방향으로 권회된 단위체의 측벽사이에 띠상의 보강대를 단면상으로 세워서 나선방향으로 권회시킬 때 보강대를 직선형으로 일체화되게 매설하도록 하고, 보강대에 소정의 위치마다 구멍을 뚫어서 단위체들의 측벽의 합성수지가 구멍로 매입되어 각 단위체와 보강대를 일체화되게 하므로써, 구조적으로 견고하여 큰 집중하중도 충분히 견디어 낼 수 있는 구조용 합성수지 파이프를 제공하기 위한 것이다.Accordingly, an object of the present invention is to erect a band-shaped reinforcing bar in a cross-section between the side walls of the unit wound in the spiral direction to be formed in a quadrangular cross section so that the reinforcing bar may be integrally embedded in a straight line when it is wound in a spiral direction, and a predetermined position is provided on the reinforcing bar. It is to provide a structural synthetic pipe that is structurally robust and can withstand large concentrated loads by making holes per hole so that the synthetic resin of the sidewalls of the units is embedded into the holes to integrate each unit and the reinforcing bar.

이하 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail.

본 고안도 그 재질은 합성수지재로서 일정한 살두께의 측벽(11)을 가지면서 단면상 사각형으로 형성되게 단위체(10)를 나선형으로 계속 밴딩하여 합성수지 파이프를 제조하는 것은 종래의 것과 다를 바 없다.The material of the present invention is a synthetic resin material, which has a side wall 11 having a constant flesh thickness, and continuously manufactures a synthetic resin pipe by spirally bending the unit body 10 to be formed in a square in cross section.

단, 본 고안에서 상기 단위체(10)의 측벽(11)내에는 그 폭이 측벽(11)보다는 약간 작은 띠상의 보강대(20)가 직선형으로 세워서 매설되도록 하므로써, 구조적으로 견고하여 큰 집중하중도 충분히 견디어 낼 수 있는 구조용 합성수지 파이프를 제공하는 것을 그 기술적 구성상의 기본적인 특징으로 한다.However, in the present invention, the band-shaped reinforcing bar 20 is slightly smaller than the side wall 11 in the side wall 11 of the unit body 10 so as to be buried in a straight line, so that it is structurally strong and a large concentrated load is sufficient. Providing a structural synthetic pipe that can withstand it is a fundamental feature of its technical construction.

또, 보강대(20)에 소정의 위치마다 구멍(21)을 뚫어서 단위체들(10)의 측벽(11)의 합성수지가 구멍(21)으로 매입되어 각 단위체(10)와 보강대(20)를 일체화되게 하는 것을 본 고안의 부수적인 특징이다.In addition, the holes 21 are drilled at predetermined positions in the reinforcing table 20 so that the synthetic resin of the side walls 11 of the units 10 is embedded into the holes 21 so that each unit 10 and the reinforcing table 20 are integrated. It is an ancillary feature of the present invention.

여기에서 상기 단위체(10)가 사각 파이프의 형상을 가지도록 하는 이유는, 보강대(20)에 측벽(11)의 합성수지가 균일한 두께로 용착되어 용착살부가 충분한 강도를 가지도록 하기 위함이다.The reason why the unit 10 has a square pipe shape is that the synthetic resin of the side wall 11 is welded to the reinforcing table 20 to a uniform thickness so that the welding salve has sufficient strength.

그리고, 보강대(20)를 단면상 직선형으로 세워서 나선방향으로 권회시키면서 측벽(11)에 매설되게 하는 이유는, 원주방향에서 중심방향으로 작용하는 토압을 효율적으로 견디면서 제작이 편리하도록 하기 위한 것이다.The reason why the reinforcing table 20 is erected in a straight line in cross section and embedded in the side wall 11 while being wound in a helical direction is to make it convenient to withstand the earth pressure acting in the circumferential direction in the center direction.

또, 상기 보강대(20)에 필요한 간격마다 필요로 하는 크기로 뚫려지는 구멍(21)은, 상기 보강대(20)가 단위체(10)의 측벽(11)내에 일체로 매설될 때 용착되는 측벽(11)의 합성수지가 매입되도록 하므로써, 마치 보강대(20)의 양측면에 합성수지의 측벽이 형성되게 하는 동시에 그 구멍(21)에 매입된 합성수지재에 의하여 양측측벽을 상호 연결하여 단위체(10)와 보강대(20)를 일체로 매설되도록 하는 역할을 수행한다.In addition, the holes 21 drilled to the required size at intervals necessary for the reinforcing bar 20 are welded to the side wall 11 when the reinforcing bar 20 is integrally embedded in the side wall 11 of the unit body 10. By embedding the synthetic resin of), it is as if the side wall of the synthetic resin is formed on both sides of the reinforcing rod 20, and at the same time, the two side walls are interconnected by the synthetic resin material embedded in the hole 21, the unit 10 and the reinforcing rod (20) ) To be buried integrally.

따라서 토압의 작용시 보강대(20)가 원주방향에서의 토압을 충분히 견디어 주면서 구멍(21)에 의해 상호 연결된 측벽(11)에 의해서 단위체(10)와 보강대(20)가 일체화 되어 단위체(10)의 상, 하면 즉, 파이프의 내, 외주면이 국부적으로 변형될 염려가 없는 우수한 구조용 합성수지 파이프를 제공할 수가 있는 것이다.Therefore, the unit 10 and the reinforcing bar 20 are integrated by the side wall 11 interconnected by the holes 21 while the reinforcing bar 20 sufficiently withstands the earth pressure in the circumferential direction when the earth pressure is applied. It is possible to provide an excellent structural synthetic resin pipe that does not have to worry about local deformation of the upper and lower surfaces, that is, the inner and outer peripheral surfaces of the pipe.

한편, 상기 보강대(20)의 재질은 강판 또는 엔지니어링 플라스틱이 선택될 수 있다. 특히, 보강대(20)의 재질이 강판으로 선택되는 경우에, 상기 구멍(21)은 보강대(20)와 단위체(10)들의 열응력이나 집중하중에 의하여 재료분리가 발생되는 것을 방지하는 데에도 큰 역할을 수행한다.On the other hand, the material of the reinforcing table 20 may be selected from steel or engineering plastics. In particular, when the material of the reinforcing rod 20 is selected as the steel sheet, the hole 21 is also large in preventing material separation from occurring due to thermal stress or concentrated load of the reinforcing rod 20 and the unit 10. Play a role.

또한 보강대(20)는 단순히 띠상의 강판 또는 엔지니어링 플라스틱을 권취하도록 되어 있어 하중을 효율적으로 받으면서 제작이 편리하고 가격이 저렴한 구조용 합성수지 파이프를 제공할 수가 있는 것이다.In addition, the reinforcing rod 20 is simply to be wound around the strip-shaped steel sheet or engineering plastics to provide a structural synthetic pipe that is easy to manufacture and low-cost while receiving the load efficiently.

상기와 같은 기술적 구성을 가지는 본 고안은 단위체가 맞닿아 용착되는 측벽내에 보강대를 직선형으로 세워서 매설되므로써, 그 용착부분이 충분한 강도를 가지게 되고 국부적인 취약부분이 존재하지 않게 되는 효과가 있는 것이다.The present invention having the technical configuration as described above has the effect that the welded portion has a sufficient strength and there is no local weakened portion by embedding the reinforcing rod in a straight line in the side wall where the unit is welded to contact.
