Description

플랜지형 파형강판{Flange type corrugated steelplate}Flanged type corrugated steelplate

본 발명은 플랜지형 파형강판에 관한 것으로서, 특히 강판산부와 강판골부를 갖는 파형강판의 장방향 양측에 각각 수평관통홀을 갖는 플랜지가 결합되어지도록 하여 파형강판이 수평방향으로 맞대어져 굴착식 터널에 이용될 수 있도록 한 것이다.The present invention relates to a flanged corrugated steel sheet, and in particular, the flanges having horizontal through-holes are coupled to both long sides of the corrugated steel sheet having a steel plate peak portion and a steel plate corrugated portion, so that the corrugated steel sheets are oriented in a horizontal direction so as to be excavated in the excavated tunnel. It can be used.

일반적으로 원통형 구조물이나 하천 배수관 등에는 강판을 소재로 한 파형강판이 사용되어지고 있다. 파형강판은 강판에 가로 또는 세로방향으로 반복되는 파형의 굴곡을 형성하여 형상강도를 높인 것으로 기존의 콘크리트 구조물에 비하여 사용이 간편하고 제조비용이 저렴한 장점을 갖는다. In general, corrugated steel sheets made of steel sheets are used for cylindrical structures and river drains. Corrugated steel sheet is formed in the steel plate to be repeated in the longitudinal or transverse wave form to increase the strength of the shape compared to the existing concrete structure has the advantage of ease of use and low manufacturing cost.

파형강판은 등록특허 10-785398(2007.12.6)호의 종래기술 및 도면에 도시된 바와 같이, 일측의 가장자리와 타측의 가장자리에 중심이 일치되는 관통홀이 각각 형성되어 하나의 파형강판에 다른 파형강판의 가장자리가 상부에서 하부로 겹쳐지고, 중심이 일치된 관통홀을 통해 볼트를 삽입하여 너트로 체결하는 과정의 반복을 통해 원통형 구조물이나 하천 배수관을 얻을 수 있게 된다.Corrugated steel sheet, as shown in the prior art and the drawings of Korean Patent No. 10-785398 (2007.12.6), through-holes are formed on the edge of one side and the other edge of the other side is formed in each of the other corrugated steel sheet By overlapping the edge of the upper to the lower, through the hole through the center coincidence through the process of fastening with a nut it is possible to obtain a cylindrical structure or river drain pipe.

그러나 이러한 파형강판을 이용한 구조물은 먼저 구조물이 설치되어지도록 한 후 구조물의 상부에 복토를 해서 덮는 개착식 터널에만 적용이 가능할 뿐 굴착식 터널의 경우, 사용하기에 어려운 원인이 있었다. 즉, 하나의 파형강판과 다른 파형강판의 가장자리가 맞대어진 상태에서 상부나 하부로부터 볼트와 너트를 체결해야 되나 국착된 터널의 내면과 파형강판의 외면 사이의 간격이 협소하고, 가로방향으로 깊어지게 됨에 따라 볼트와 너트를 관통홀에 삽입하는 것부터 난해한 원인이 있었다. 이러한 원인으로 인하여 시공기간이 길어지게 됨과 동시에 시공비가 증가되는 또 다른 문제점이 있었다.However, the structure using the corrugated steel sheet can be applied only to the open-type tunnel covered by covering the upper part of the structure after the structure is installed first, and in the case of the excavated tunnel, it was difficult to use. That is, the bolt and nut should be fastened from the top or the bottom in the state where the edges of one corrugated steel sheet and the other corrugated steel sheet are butted together, but the gap between the inner surface of the tunnel and the outer surface of the corrugated steel sheet is narrow and deep in the horizontal direction. As a result, it was difficult to insert the bolt and nut into the through hole. Due to this cause, the construction period is long and at the same time, there is another problem that the construction cost increases.
