본 발명은 복부파형강판과 피에스씨 콘크리트가 합성된 교량의 상부 구조 형식에서 복부 파형강판과 콘크리트를 기역형강(ㄱ자형강)과 스터드로 결합시킨 복부파형강판과 콘크리트의 합성 방법에 관한 것으로서, 더욱 상세히 설명하면 복부파형강판 상·하단에서 좌·우 양측에 대칭으로 기역형강(ㄱ자형강)을 보울트로서 결합하여 이를 콘크리트와 합성시키는 것에 관한 것이다.The present invention relates to a method for synthesizing an abdominal corrugated steel sheet and concrete in which an abdominal corrugated steel sheet and concrete are combined with a base steel (a-shaped steel) and a stud in a superstructure type of a bridge in which an abdominal corrugated steel sheet and a PSC concrete are synthesized. In the description, the upper and lower abdomen of the abdominal corrugated steel sheet is symmetrically coupled to the left and right sides (a-shaped steel) as a bolt to combine it with concrete.

예시도 1은 종래의 합성구조에 관한 사시도로서, 복부파형강판(1)의 상·하단에 플랜지가 부착되고 그 플랜지(2)에는 다수의 스터드(3)가 부착된다. Exemplary Fig. 1 is a perspective view of a conventional composite structure in which a flange is attached to the upper and lower ends of the abdominal corrugated steel sheet 1, and a plurality of studs 3 are attached to the flange 2.

예시도 2는 예시도 1의 단면도로서 플랜지 위에 콘크리트가 합성된 것을 나타낸다. Exemplary FIG. 2 is a cross-sectional view of Exemplary FIG. 1 showing that concrete is synthesized on a flange.

이러한 방법은 복부파형강판(1)의 상·하단에 플랜지를 용접에 의하여 부착함에 있어서 파형의 요철부를 연속하여 용접을 하여야 하는바 이로 인한 상당한 번거로움이 수반되며 또한 예시도 2 와 같이 콘크리트가 플랜지 위의 스터드를 감싸서 그로 인한 부착력 만으로 결합되므로서 보다 더 견고한 합성을 기대하기 어렵게 된다.In this method, the flanges are attached to the upper and lower ends of the abdominal corrugated steel sheet 1 by welding. Therefore, the convex and concave and convex portions must be continuously welded. By wrapping the studs above and combining them only with the resulting adhesion, it becomes difficult to expect a more robust synthesis.

예시도 3은 종래 합성구조에 관한 또다른 예시도로서, 복부파형강판의 상·하단에 일정간격으로 다수의 관통공(7)을 천공하고 그 관통공 속으로 결합 철근(5)을 배치하고 그 결합 철근(5)을 고정시키기 위한 종방향 철근(6)을 배치하여 결합 철근과 종방향 철근을 가는 철선 등으로 묶어서 고정시키게 된다. Exemplary FIG. 3 is another exemplary diagram of a conventional composite structure, which drills a plurality of through holes 7 at regular intervals at upper and lower ends of an abdominal corrugated steel sheet, and arranges coupling bars 5 into the through holes. The longitudinal reinforcing bars 6 are disposed to fix the coupling reinforcing bars 5, and the binding reinforcing bars and the longitudinal reinforcing bars are bundled and fastened with thin wires.

예시도 4는 예시도 3의 단면도로서 복부파형강판의 상단에 콘크리트가 합성된 형상의 단면도이다. FIG. 4 is a cross-sectional view of the shape in which concrete is synthesized on the upper end of the abdominal corrugated steel sheet as a cross-sectional view of FIG.

이와 같은 합성 방법은 복부파형강판(1)의 상·하단에 수많은 관통공을 천공하여야만 하는 번거로움이 있으며 또한 콘크리트가 관통공 속의 결합 철근과 함께 파형강판 상·하단의 일정 부분을 감싸서 부착 결합되는 형태이기는 하지만 콘크리트와 파형강판의 박리 및 탈락에 저항하는 것은 근본적으로 관통공속의 결합 철근이므로 이 또한 보다 더 견고하고 충분한 합성을 기대하기는 어렵다.Such a synthetic method has the hassle of having to drill a large number of through holes in the upper and lower ends of the abdominal corrugated steel sheet (1). Although it is morphological, it is difficult to expect more robust and sufficient synthesis since it is basically a binding reinforcing bar through the resistance to peeling and dropping of concrete and corrugated sheet.

본 발명은 상술한 바와 같은 종래의 결점을 해결하기 위한 것으로서, 복부파형강판의 상·하단에서 좌·우 대칭으로 기역형강(ㄱ자형강)을 보울트로서 결합하고 기역형강(ㄱ자형강)에는 다수의 스터드를 취부하여 시공성이 뛰어나고, 콘크리트와 부착 결합력을 한층 더 향상시키는 복부파형강판과 콘크리트의 합성구조를 제공함에 목적이 있다.The present invention is to solve the conventional drawbacks as described above, combining the left and right symmetrical steel (A-shaped steel) as a bolt in the upper and lower symmetry of the abdominal corrugated steel sheet and a number of studs in the base steel (A-shaped steel) The purpose of the present invention is to provide a composite structure of the abdominal corrugated steel sheet and concrete, which is excellent in workability and further improves adhesion to concrete.

상기와 같은 기술적 목적을 실현시키기 위한 본 발명은 복부파형 강판의 상·하단에 기역형강(ㄱ자형강)을 좌·우 양측에 대칭형으로 결합하되 기역형강(ㄱ자 형강)과 복부 파형강판의 각 접착면에는 보울트를 체결하여 복부파형강판과 기역형강(ㄱ자형강)을 일체로 조립하고, 기역형강(ㄱ자형강)의 수평면에는 다수의 스터드를 취부 결합하여 이들 전체가 콘크리트 속에 일체 구조를 매립되도록 한 것이다.According to the present invention for realizing the above technical object, the bonded surface of the base steel (A-shaped steel) and the abdominal corrugated steel sheet are symmetrically coupled to both the left and right sides of the abdominal corrugated steel sheet at the upper and lower ends of the abdominal corrugated steel sheet. The abdominal corrugated steel plate and the reinforcement section steel (a-shaped steel) are integrally assembled by fastening bolts, and a plurality of studs are attached to the horizontal surface of the reinforcement section steel (a-shape steel) so that the entire structure is embedded in concrete.

본 발명은 복부파형강판과 콘크리트를 합성함에 있어서 부착 결합력을 한층 더 향상시키기 위하여 복부파형강판(1)의 상·하단에서 종방향으로 기역형강(ㄱ자형강)(8)을 좌·우 양측에 대칭이 되도록 결합하되 기역형강(ㄱ자형강)(8)의 수직부와 접하는 복부파형강판(1)의 각 접합면에는 결합보울트(9)를 체결하고, 기역형강(ㄱ자형강)(8)의 수평부에는 다수의 스터드(3)를 용접 취부하여 복부파형강판(1)의 상·하단과 기역형강(ㄱ자형강)(8) 및 스터드(3)가 콘크리트 속에 일체형으로 매립되도록 한 것이다.In the present invention, in order to further improve the bonding strength in synthesizing the abdominal corrugated steel sheet and concrete, symmetrical steel (a-shape steel) 8 is symmetrically formed on both sides of the abdominal corrugated steel sheet 1 in the longitudinal direction from the upper and lower ends thereof. The coupling bolt (9) is fastened to each joint surface of the abdominal corrugated steel sheet (1) in contact with the vertical portion of the base steel (A-shaped steel) (8), and the horizontal portion of the base steel (8) There are a plurality of studs (3) by welding to the upper and lower ends of the abdominal corrugated steel sheet (1) and the base steel (a-shaped steel) (8) and the stud (3) to be integrally embedded in the concrete.

복부파형강판(1)의 상·하단에 결합되는 기역형강(ㄱ자형강)(8)은 각각 파형강판(1)의 굴곡면에 따라 일정간격으로 순차적으로 접하게 되며, 이와 같이 파형강판(1)과 기역형강(ㄱ자형강)(8)이 접하는 각 면에는 적당한 수의 결합보울트(9)를 체결하는 것이다.The base-type steel (a-shape steel) 8 coupled to the upper and lower ends of the abdominal corrugated steel sheet 1 is sequentially contacted at predetermined intervals according to the curved surface of the corrugated steel sheet 1, and thus the corrugated steel sheet 1 and On each side of the base steel (a-shaped steel) (8) is to fasten a suitable number of coupling bolts (9).

결합보울트(9)가 체결되는 부위는 복부파형강판의 각 굴곡면에 의해 일정하게 항상 공간이 형성되므로 작업성이 뛰어나고, 콘크리트를 합성시킬 때 상기 공간부에 콘크리트가 채워지므로 더욱더 견고한 부착 결합력을 갖게 된다.Part of the coupling bolt 9 is fastened because the space is always formed constantly by each curved surface of the abdominal corrugated steel sheet is excellent in workability, and the concrete is filled in the space when synthesizing concrete has a more firm attachment bond strength do.

복부파형강판의 상·하단에 좌·우 대칭형으로 각각 결합된 기역형강(ㄱ자형 강)의 수평면에서 용접으로 취부되는 스터드(3)는 파형강판과 기역형강(ㄱ자형강)을 결합하기 전 또는 결합 후에도 용접 취부가 가능하다.The stud (3), which is mounted by welding in the horizontal plane of the base steel (A-shaped steel), which is symmetrically coupled to the upper and lower ends of the abdominal corrugated steel sheet, respectively, is connected to the corrugated steel sheet and the base steel (A-shaped steel) before or Welding mounting is possible afterwards.

예시도 6 은 본 발명에 따른 복부파형강판과 콘크리트의 합성 상태를 나타낸 일부절개사시도로서 콘크리트 내에 파형강판(1)의 일부와 기역형강(ㄱ자형강)(8) 및 스터드(3)가 매립되어 일체형으로 된 것을 나타낸다.Exemplary FIG. 6 is a partial cutaway perspective view showing a composite state of an abdominal corrugated steel sheet and concrete according to the present invention. A portion of the corrugated steel sheet 1, the base steel (8) and the stud (3) are embedded in the concrete. Indicates that

이와 같이 콘크리트 속에 기역형강(ㄱ자형강)(8)과 스터드(3) 및 파형강판(1)의 일부가 일체형으로 결합되어 매립되므로 종래의 방법에 비하여 복부파형강판과 콘크리트의 부착 결합력이 한층 더 증가된 보다 더 견고한 합성구조를 기대할 수 있게 되는 것이다.Thus, part of the base steel (a-shaped steel) (8) and the stud (3) and corrugated steel sheet (1) is embedded in the concrete integrally embedded, so that the bonding bond strength of the abdominal corrugated steel sheet and concrete is further increased compared to the conventional method You can expect a more robust composite structure.

본 발명은 복부파형강판과 콘크리트를 합성함에 있어서 파형강판(1)의 상·하단에 수평 방향으로 기역형강(ㄱ자형강)(8)을 좌·우 양측에 대칭형이 되도록 결합하되 기역형강(ㄱ자형강)(8)의 수직부와 접하는 복부파형강판(1) 각 접합면에는 결합보울트(9)를 체결하고, 기역형강(ㄱ자형강)(8)의 수평부에는 다수의 스터드(3)를 용접 취부하여 파형강판(1)의 상·하단과 기역형강(ㄱ자형강)(8) 및 스터드(3)가 일체 구조로 결합되어 콘크리트 속에 매립되도록 한 것으로서 기역형강(ㄱ자형강)을 보울트로서 결합하도록 되어 있기 때문에 종래의 방법에 비하여 복부파형강판의 요철면을 따라 연속되는 플랜지의 용접작업과 수많은 관통공을 천공하는 등의 작업의 곤란성을 한층 더 개선시키면서도 복부파형강판의 상·하단과 기역형강(ㄱ자형강)과 스터드가 일체구조로 콘크리트 속에 매립되므로서 콘크리트와의 부착면 적이 한층 더 증가되어 보다 더 견고한 콘크리트와의 결합력을 기대할 수 있게 되는 것이다.The present invention combines the base steel (A-shaped steel) (8) in the horizontal direction at the upper and lower ends of the corrugated steel sheet and concrete to be symmetrical to both the left and right sides in synthesizing the abdominal corrugated steel sheet and concrete (A-shaped steel) Fastening bolts (9) are joined to each joint surface of the abdominal corrugated steel sheet (1) in contact with the vertical part of the (8), and a plurality of studs (3) are welded to the horizontal part of the base steel (8). The upper and lower ends of the corrugated steel sheet 1 and the base steel (a-shaped steel) (8) and the stud (3) are combined in an integrated structure to be embedded in concrete, and the base steel (a-shaped steel) is coupled as a bolt. Therefore, compared to the conventional method, the upper and lower ends of the abdominal corrugated steel sheet and the non-linear steel (A-shaped steel) can be further improved while further improving the difficulty of welding continuous flanges along the uneven surface of the abdominal corrugated steel sheet and drilling a large number of through holes. ) And studs Jolo so embedded in the document attached to the concrete surface of the concrete and have been further increased it is possible to expect a more robust bonding with the concrete more.
