Description

철근콘크리트 강합성 파형강판 구조물{CORRUGATED STEELPLATE STRUCTURE OF STEEL CONCRETE STEEL COMPOSITION}Reinforced concrete composite corrugated steel sheet structure {CORRUGATED STEELPLATE STRUCTURE OF STEEL CONCRETE STEEL COMPOSITION}

본 발명은 철근콘크리트 강합성 파형강판 구조물에 관한 것으로서, 특히 파형강판이 길이방향으로 설치되어진 베이스아치구조물의 상부에 철근콘크리트보강구조가 구비되어지도록 함으로써, 단면적을 넓혀 하중이 고르게 분포되어질 수 있도록 하는 가운데 저항력을 높여 변형이나 파손을 방지할 수 있도록 한 것이다.The present invention relates to a reinforced concrete composite corrugated steel sheet structure, and in particular, by having a reinforced concrete reinforcing structure is provided on top of the base arch structure in which the corrugated steel sheet is installed in the longitudinal direction, so that the load can be evenly distributed Increased resistance in the middle to prevent deformation or breakage.

일반적으로 산과 골이 반복되는 형태로 절곡된 파형강판을 축방향으로 결합시켜 얻어진 구조물은 지하통로, 용수로, 배수로, 호안용 셀, 배수로, 지붕 및 창고 등 여러 용도로 사용되어지고 있다.In general, a structure obtained by axially combining a corrugated steel sheet bent in a repeating shape of a mountain and a valley is used for various purposes such as underground passages, water passages, drainage passages, revetment cells, drainage passages, roofs, and warehouses.

파형강판 구조물은 크기가 작을 경우, 벤딩된 하나의 강판이 이용되어지고, 크기가 클 경우, 벤딩 공정에서 벤딩율을 크게하여 제조된 것을 겹쳐 볼팅 조립공정으로 설치되어지게 된다.When the corrugated steel sheet structure is small in size, one bent steel sheet is used. When the corrugated steel sheet structure is large in size, the corrugated steel sheet structure is installed by a bolting assembly process by overlapping the one manufactured by increasing the bending rate in the bending process.

파형강판을 이용한 구조물의 시공은 기초지반에 시공된 채널에 볼팅으로 파형강판의 하부가 직각 되도록 설치된 후 설치된 파형강판의 가장자리에 다른 파형강판의 가장자리가 서로 겹쳐지게 맞대어진 상태에서 볼팅작업을 반복하여 파형강판으로 이루어진 구조물을 얻을수 있게 된다.The construction of the structure using the corrugated steel plate is installed so that the lower part of the corrugated steel plate is perpendicular to the channel installed on the foundation ground, and then the bolting operation is repeated while the edges of the corrugated steel sheet are overlapped with each other and overlapped with each other. A structure consisting of corrugated steel sheet can be obtained.

이러한 파형강판 구조물은 얇은 파형강판에 주름이 연속되어지는 형태를 갖도록 형성되어 있음으로써, 경간의 길이가 짧은 곳에는 사용하기 충분하나 경간의 길이가 긴 경우, 종단면적이 작아 압축력에 대한 저항력이 줄어들어 부분적인 변형이 발생되는 원인이 있었다.Since the corrugated steel sheet structure is formed to have a continuous corrugation form on the thin corrugated steel sheet, the corrugated steel sheet is sufficient to be used where the span is short, but when the span is long, the longitudinal section is small and the resistance to compressive force is reduced. There was a cause for partial deformation.

이러한 원인을 해소하기 위한 방안으로 등록특허 698028(2007.3.15)호의 파형강판 구조물의 보강방법 및 보강구조가 제안되었고, 제안된 보강구조는 파형강판의 앵커볼트 삽입홈에 앵커볼트가 결합되어지고, 앵커볼트가 철근과 와이어로 결속되어진 상태에서 파형강판의 둘레를 따라 콘크리트가 경화되어지는 라이어에 의하여 보강되어지도록 하였으나, 천공된 앵커볼트에 의한 단면이 감소됨에 따라 국부적인 하중이 작용하게 될 경우, 변형이 발생되는 문제점이 있었다.As a method for solving this cause, a reinforcing method and a reinforcing structure of the corrugated steel sheet structure of Patent No. 698028 (2007.3.15) have been proposed, and the proposed reinforcing structure has an anchor bolt coupled to the anchor bolt insertion groove of the corrugated steel sheet, When anchor bolts are bound with reinforcing bars and wires, the concrete is reinforced by a liar that hardens concrete along the circumference of the corrugated steel sheet. There was a problem that deformation occurs.

본 발명은 파형강판의 단면이 감소되는 것을 방지할 수 있도록 하는 가운데 변형을 방지하여 수명이 단축되는 것을 막을 수 있도록 하고, 아울러 파형강판 구조물의 내면이 미려하게 될 수 있도록 한 것이다. The present invention is to prevent the reduction of the cross section of the corrugated steel sheet to prevent deformation and to prevent the shortened life, and also to make the inner surface of the corrugated steel sheet structure beautiful.
