[산업의상의 이용분야][Application Field of Industrial Costume]
본 발명은 내측탱크상부이외의 외측에 간격을 마련하여 외측탱크를 형성한 2중 탱크의 구조에 관한 것이다.The present invention relates to a structure of a double tank in which an outer tank is formed by providing a gap outside the upper portion of the inner tank.
[종래의 기술][Prior art]
일반적으로, 급유소의 지하에 매설되는 지하탱크는 2중구조로 하여 만일 내측탱크가 손상하여도 내측탱크내의 기름이 외측탱크에 의해서 외부로 유출되지 않도록 되어 있다. 그러한 2중 탱크는 본출원인에 의한 일본 특공평3-75434호 공보에 개시되어 있다. 그렇지만 그러한 2중 탱크는 그의 구조상 중량이 무겁고 또 제조가 번거로워지게 되어 있었다.In general, underground tanks buried underground in a gas station have a double structure so that oil in the inner tank does not flow out to the outside by the outer tank even if the inner tank is damaged. Such a double tank is disclosed in Japanese Patent Application Laid-Open No. 3-75434 by the present applicant. Such a double tank, however, was heavy in structure and cumbersome to manufacture.
[발명이 해결하고져 하는 과제][Problem to Solve Invention]
따라서 본 발명의 목적은 비교적 가볍고도 튼튼하며, 또한 제조가 용이한 2중 탱크의 구조를 제공하는데에 있다.It is therefore an object of the present invention to provide a structure of a double tank which is relatively light and robust and which is easy to manufacture.
[발명을 해결하기 위한 수단][Means for solving the invention]
본 발명에 의하면 내측 탱크 상부 이외의 외측에 간격을 마련하여 외측 탱크를 형성한 2중 탱크의 구조에 있어서, 상기 외측 탱크가 섬유강화플라스틱으로 구성되며, 상기 내측 탱크의 상부 표면에는 섬유강화플라스틱으로 형성된 외측이 피복되어 있으며 상기 피복된 외층의 하단이 상기 외측탱크와 만탱크시의 액면 위치 부근에서 접속되어 있는 것을 특징으로 하고 있다.According to the present invention, in the structure of the double tank in which the outer tank is formed outside the upper portion of the inner tank to form an outer tank, the outer tank is made of fiber reinforced plastic, and the upper surface of the inner tank is made of fiber reinforced plastic. The formed outer side is coat | covered, The lower end of the coat | covered outer layer is connected with the said outer tank in the vicinity of the liquid surface position at the time of a full tank, It is characterized by the above-mentioned.
[작용효과의 설명][Description of Effect]
따라서 섬유강화플라스틱(이하 단지 FRP라고 한다)은 철강에 비해서 가볍고 또 가공이 용이하며 더구나 접착이나 용착에 의해 일체화가 용이하다. 특히 본 발명의 FRP는 외부의 토사와 접하게 도지만 FRP는 그 자체가 방식성능을 갖고 있어서, 외측탱크의 방식처리가 불필요하게 된다.Therefore, fiber-reinforced plastics (hereinafter referred to simply as FRP) are lighter and easier to process than steel, and are more easily integrated by adhesion or welding. In particular, the FRP of the present invention is in contact with the external soil, but the FRP itself has an anticorrosive performance, so the anticorrosive treatment of the outer tank is unnecessary.
또 발명에서는 외측탱크와 내측탱크와의 사이에 스페이서등을 사용하지 않는다. 그러기 때문에 탱크의 일부에서는 내측탱크가 외측탱크와 접속하도록 되지만, 부분적으로 접촉하여도 다른 부분에 약간의 간격이 있게되며, 누설된 액은 그의 간격으로 부터 흘러내려 하부에 고여서 액의 누설을 검지할 수 있게 된다.In the present invention, a spacer or the like is not used between the outer tank and the inner tank. Therefore, in some tanks, the inner tank is connected to the outer tank, but even in partial contact there is a slight gap in the other part, and the leaked liquid flows out of the gap and collects at the bottom to detect the leakage of liquid. You can do it.
그리고 탱크의 상부는 FRP에 의해 피복되어져 있으므로 상기와 같이 내측탱크와 외측탱크와의 사이에 상대적인 변위가 생겨도 전체적으로 내외측의 양 탱크는 일체화 되어 있어서 접촉한 곳 이외에서는 간격이 존재한다. 그리고 내측탱크의 상부를 노출한 것에 대해서 강도적으로도 바람직하다.In addition, since the upper part of the tank is covered by the FRP, even if a relative displacement occurs between the inner tank and the outer tank as described above, both inner and outer tanks are integrated so that there is a gap other than the contact point. It is also preferable in strength to expose the upper portion of the inner tank.
[바람직한 실시의 양태][Preferred Embodiment]
본 발명의 실시에 있어서, 외측탱크를 형성하려면, FRP의 평판을 구부려서 가공해도 좋고, 또 내측 탱크의 탱크 형상에 따르는 형상으로 만곡된 판을 사용하여도 좋다.In the practice of the present invention, in order to form the outer tank, the plate of the FRP may be bent and processed, or a plate curved in a shape conforming to the tank shape of the inner tank may be used.
또, 내측탱크는 강판으로 제작하므로 그의 용접부에 두툼한 부분이 생기나 이 두툼한 부분이 외측 탱크 내면에 접촉하므로서 내외측탱크 사이에 형성된 공간부(간격)가 연통되지 아니하고 단절되는 현상을 방지하기 위하여 그 두툼한 부분에 대향하는 외측탱크의 연결부위는 직접 맞대어 설치하지 않고 간격을 벌려서 FRP판을 설치하고 그의 벌려진 외측으로 다른 FRP판을 접착 또는 융착하므로써 용접부의 두툼한 부분이 외측탱크 바닥면에 닿지 않도록 한다.In addition, since the inner tank is made of steel sheet, a thick portion is formed in the welded portion thereof, but the thick portion is in contact with the inner surface of the outer tank, so that the space (thickness) formed between the inner and outer tanks is not communicated with each other to prevent disconnection. The connection part of the outer tank facing the part should be spaced apart without direct installation but the FRP plate is installed and the thick part of the weld is not allowed to touch the bottom of the outer tank by gluing or fusion of another FRP plate.
