본 발명은 콘크리트 슬래브(slab) 구조물의 거푸집 설치에 사용되는 구조재 및 이를 이용한 거푸집의 설치구조로서, 콘크리트의 양생시 슬래브 하부의 거푸집을 지지하는 가설구조물을 설치함에 있어서, 3개의 폐단면이 조합되어 구성된 삼중폐단면강과 형강 등을 조합하되, 동바리 등의 수직구조물에 의하여 지지되고 서로 평행한 한쌍의 형강 사이에 다수의 삼중폐단면강을 밀착배열함으로써 거푸집 하부 수직부재를 최소화할 수 있도록 한 것이다.The present invention is a structural material used to install the formwork of the concrete slab (slab) structure and the installation structure of the formwork using the same, in the installation of the temporary structure to support the formwork under the slab during curing of concrete, three closed sections are combined Combining the configured triple-closed section steel and section steel, but to support the vertical structure of the copper barrier and a plurality of triple-closed section steel in close contact between the pair of section steel parallel to each other to minimize the formwork lower vertical member.

콘크리트 슬래브 구조물의 타설 및 양생에 있어서, 슬래브용 거푸집은 기둥이나 벽체용 거푸집과 달리 그 구조적 특성상 자립할 수 없으며, 슬래브에 소기의 강도가 확보될 때까지 동바리와 같은 가설 수직부재나 기설 구조물에 의하여 지지되어야 한다.In the casting and curing of the concrete slab structure, unlike the column or wall formwork, the slab formwork cannot be self-supporting due to its structural characteristics. Should be supported.

일반적인 콘크리트 구조물의 설계 및 시공에 있어서, 거푸집은 타설되는 콘크리트를 소정의 형태로 적재하는 주형의 역할만을 수행할 뿐, 콘크리트의 자중을 지지하지는 못하는 것으로 간주되며, 따라서 도 1에서와 같이, 거푸집(200)의 하부에는 다수의 장선(210) 및 멍에(220)가 설치되어 콘크리트(400)의 자중을 분담하여 수직 가설구조물인 동바리(300)에 전달하게 된다.In the design and construction of a general concrete structure, the formwork is only considered to serve as a mold for loading the cast concrete in a predetermined form, and does not support the weight of the concrete. Therefore, as shown in FIG. A plurality of joists 210 and the yoke 220 are installed in the lower part of the 200 to share the weight of the concrete 400 and transmit it to the copper bar 300 which is a vertical construction.

그러나, 이러한 종래의 슬래브용 거푸집(200)은 그 구조가 복잡하고 과도한 자재가 소요될 뿐 아니라, 양생간 거푸집(200) 및 하부구조물의 변형을 방지하기 위하여 많은 수의 동바리(300)가 소요되는 문제점이 있었다.However, the conventional slab formwork 200 is not only complicated in structure and takes excessive material, but also requires a large number of copper wheels 300 to prevent deformation of the formwork 200 and the substructure during curing. There was this.

특히, 도로 상부를 통과하는 교량구조물의 경우 과도한 동바리(300)의 설치로 도로를 잠식하게 되어 교통체증을 유발할 뿐 아니라, 거푸집(200)의 설치 및 해체시 숙련공이 필요하고 장시간의 작업시간이 소요되는 심각한 문제점이 있었다.In particular, in the case of a bridge structure passing through the upper part of the road, the installation of excessive copper wheels 300 may encroach on the road, causing traffic jams, and skilled workers are required for installing and dismantling the formwork 200, which takes a long time. There was a serious issue of becoming.

본 발명은 전술한 문제점을 감안하여 창안한 것으로, 강철판을 절곡하여 3개의 폐단면이 조합된 삼중폐단면강을 구성하고, 한쌍의 평행한 형강의 플랜지와 플랜지 사이에 다수의 삼중폐단면강을 끼워서 밀착 배열함으로써, 우수한 강성의 슬래브 거푸집 지지구조물을 시공할 수 있도록 한 것이다.The present invention was devised in view of the above-described problems, and the steel plate is bent to form a triple closed cross section steel in which three closed cross sections are combined, and a plurality of triple closed cross sections are inserted between the flanges and the flanges of a pair of parallel section steels. By arranging, it is possible to construct a slab formwork supporting structure of excellent rigidity.
