[산업상 이용분야][Industrial use]

본 고안은 내압 합성수지나선관용 보강철판 매립구조에 관한 것으로, 특히 내압합성수지나선관의 관벽 내부에 매립되는 보강철판의 상호간을 겹이음 되도록 하여 그 보강철판의 상호간이 견고하게 연결되도록 할 뿐만 아니라 재료의 절감을 실현시켜 줄 수 있도록 된 내압 합성수지나선관용 보강철판 매립구조에 관한 것이다.The present invention relates to a reinforcing steel plate embedded structure for a pressure-resistant synthetic resin spiral pipe, and in particular to overlap the reinforcing steel plates embedded in the pipe wall of the pressure-resistant synthetic resin spiral pipe so that the reinforcing steel plates are firmly connected to each other as well as the material The present invention relates to a reinforcing steel plate embedded structure for pressure-resistant synthetic resin spiral pipes that can realize savings.

[종래기술][Private Technology]

일반적으로 합성수지나선관은 금속재의 강관에 비하여 경량이며 취급이 용이한 등의 이유로 상·하수도관 및 그 외의 용도로 폭 넓게 사용되고 있는 바, 이와 같은 합성수지나선관은 파형으로 절곡되는 외면과 그 외면의 내부에 평활면으로서 내면이 일체로 용접되는 구조로 제조되어, 합성수지재질이 가지는 구조적 강도가 취약한 결점을 보완하도록 하였다.In general, synthetic resin spiral pipes are widely used for water and sewage pipes and other purposes because of their light weight and ease of handling, compared to metal steel pipes. The inner surface is integrally welded as a smooth surface inside, so as to compensate for the weak structural strength of the synthetic resin material.

그러나, 이러한 파형구조의 합성수지나선관 역시 지중에 매설된 상태에서 작용되는 토압, 국부적인 하중 등에 구조적인 강도를 가지지 못하여 쉽게 변경되거나 파손되는 등의 결함이 있었다.However, the synthetic resin spiral tube of such a corrugated structure also has a defect such as not easily changed or broken due to the lack of structural strength, such as earth pressure, local load acting in the underground state.

상기한 문제점을 감안하여 최근에는 관벽내부에 보강철판이 일체로 매립되어서 구조적인 강도가 보완되도록 된 내압 합성수지관이 개발되어 사용되고 있다.In view of the above problems, recently, pressure-resistant synthetic resin tubes have been developed and used so that structural strength is complemented by reinforcing steel plates integrally embedded in the pipe walls.

이와 같은 내압 합성수지관 중의 하나는 국내 실용신안공보 제92-6733호에 나선형 보강철판의 보강돌부 양측벽에 횡방향으로 연장되는 양측 연장부의 연부에 서로 겹쳐져 맞물리는 절곡 접합단이 형성되고, 그 양측 절곡 접합단이 서로 밀착된 상태로 걸려지는 걸림 접합부로서 일연체로 연결 접합되는 구조로서 보강철심이 합성 수지나선관의 관벽 내·외면에 일체로 매립되도록 된 내압 합성수지나선관이 출원공고되었다.One of such pressure-resistant synthetic resin pipes is formed in Korea Utility Model Publication No. 92-6733, bent joint ends overlapping each other on the edges of both side extensions extending laterally on both side walls of the reinforcement protrusions of the spiral reinforcement steel plate. A pressure-resistant synthetic resin spiral tube has been disclosed that a reinforcing iron core is integrally embedded in the inner and outer surfaces of a synthetic resin spiral tube as a structure in which the bending joint ends are held in close contact with each other.

[종래기술의 문제점][Problems with Prior Art]

그런데, 이는 합성수지나선관의 관벽에 매립되는 보강철판의 양측 연장부를 연결하여 일연체로 걸어물려 접합시킴으로써, 여기에 작용되는 토압이나 국부적인 하중에 대응되는 구조적인 강도를 가지는 장점은 있으나, 이와 같은 종래의 내압 합성수지나선관은 보강철판 양측단에 절곡 접합단이 걸려 접합되어 그 보강철심 상호간이 연결되므로, 제작상의 문제와 함께 재료비가 상승되는 문제점이 있었다.However, this has the advantage of having a structural strength corresponding to the earth pressure or local load applied thereto by connecting the two side extensions of the reinforcing steel plate embedded in the pipe wall of the synthetic resin spiral pipe and hooked together in a single body, Since the conventional pressure-resistant synthetic resin spiral tube is bent and joined to both ends of the reinforcing steel plate and the reinforcing iron cores are connected to each other, there is a problem in that the material cost is increased along with manufacturing problems.

즉, 이와 같은 이유는 첫째, 보강철판의 상호간이 걸려 접합하기 위한 절곡 접합단이 형성되고, 그 절곡 접합단을 압착하여야 하는 등의 문제로 작업공정이 복합한 제작상의 문제점이 있고, 둘째 보강철판의 양측단에 형성되는 절곡 접합단의 절곡부위 만큼의 불필요한 재료의 사용으로 인한 제작원가가 상승되는 등의 문제점이 있었다.That is, the reason for this is, first, there is a problem in the production of a composite work process due to the problem that the bending joint ends for forming the joints of the reinforcing steel sheet to each other, and crimping the bending joint ends, and the second reinforcing steel sheet There was a problem that the production cost is increased due to the use of unnecessary material as much as the bent portion of the bent joint formed on both side ends of the.

[고안의 목적][Purpose of designation]

이에 본 고안은 상기한 바와 같은 제문제점을 해결하기 위하여 안출된 것으로서, 보강철판의 양측단에 최소폭을 가지는 대접면 상호간이 겹이음되는 구조로 연결되어, 첫째 전체적인 구조적 강도의 증진과 함께 겹이음부의 강도를 증대시키고, 둘째, 불필요한 재료의 사용을 배제하여 전체적인 원가를 절감시켜 줄 수 있도록 한 내압 합성수지나선관용 보강철판 매립구조를 제공하는데 그 목적이 있다.Therefore, the present invention was devised to solve the problems as described above, and is connected to the structure in which the mating surfaces having the minimum width are overlapped with each other at both ends of the reinforcing steel plate, so that the first layer is improved with the improvement of the overall structural strength. The purpose of the present invention is to provide a reinforcing steel plate embedded structure for pressure-resistant synthetic resin spiral pipes to increase the strength of the joint and to reduce the overall cost by eliminating unnecessary materials.
