또한, 도 3에서 도시된 바와 같이 종래 4각형 중공박스하판(33)과 I빔형강(34)상부의 접합구성에서는 2지점 용접접합과 함께 볼트 및 너트체결도 병행되도록 위험기계안전인증심사시에 권장되고 있다.In addition, as shown in FIG. 3, the conventional quadrangular hollow box
상기와 같은 단면구성방법은 볼트 및 너트의 풀림현상이 예측되었고 작업공정도 길어질 뿐 아니라 I빔형강(34)의 불필요한 공간을 줄이지 못하는 문제점이 있었다.The cross-sectional configuration method as described above has a problem that the loosening of the bolts and nuts is predicted and the working process is not only long but also does not reduce the unnecessary space of the I-
본 발명은 상기한 종래의 문제점들을 해결하기 위한 것으로서 그 목적은 크레인거더에 가하여지는 하중에 대하여 허용응력을 증가시킬 수 있고 I빔형강(34)의 불필요한 공간을 제거하며 용접고정을 2지점에서 4지점으로 증가시켜 안전성과 작업의 효율성을 제공하는 데 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and its object is to increase the allowable stress with respect to the load applied to the crane girder, to remove unnecessary space of the I-
상기의 과제를 해결하기 위해 본 발명은 하나의 상판(1, 21)과; 한 쌍의 하판(3A, 3B, 23A, 23B)과; 한 쌍의 측면판(2A, 2B)으로서; 5각형 또는 3각형 중공박스형태로 용접접합시키고 그 아래에 한쌍의 하판(3A, 3B)속으로 I빔형강(4, 24)이 위쪽방향으로 삽입되어져 I빔형강측면(4A, 24A)과 한 쌍의 하판(3A, 3B, 23A, 23B)이; 4지점 접합되어지게 완성하여 크레인거더로 사용되며 상기와 같이 단면구성방법을 기술적요지로 한다.In order to solve the above problems, the present invention includes a single top plate (1, 21); A pair of
상기와 같이 본 발명에 의하면 4각형 중공단면구성에 비하여 5각형 또는 3각형 중공단면구성은 단면적이 크게 증가되므로 동일한 하중조건에서 외형크기의 축소와 불필요한 공간을 제거하는 효과가 있다.As described above, according to the present invention, the pentagonal or triangular hollow section configuration has a larger cross-sectional area than the quadrangular hollow section configuration, thereby reducing the size and removing unnecessary space under the same load conditions.
또한, I빔형강(4, 24)이 한 쌍의 하판(3A, 3B, 23A, 23B)속으로 삽입되어 4지점에 용접고정되므로서 볼트 및 너트 체결작업이 제외되어 작업의 효율성이 향상될 수 있고 바닥아래방향에서 오는 수직하중으로부터 증가된 단면적에 따른 안전성증대 효과가 있다.In addition, since the I-

이하, 본 발명의 바람직한 실시예를 도면을 참조하여 보다 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명에 따른 모노레일형 크레인거더의 단면구성방법에서 도 1은 5각형 중공단면구성도이고 도 2는 3각형 중공단면구성도이다.In the cross-sectional configuration method of a monorail crane girder according to the present invention, Figure 1 is a pentagonal hollow cross-section configuration and Figure 2 is a triangular hollow cross-sectional configuration diagram.
먼저, 도 1에서 도시된 바와 같이 하나의 상판(1)과 한 쌍의 측면판(2A, 2B)이 수직교차로 용접접합되고; 수직상태인 한 쌍의 측면판(2A, 2B)과 한 쌍의 하판(3A, 3B)이 경사로 용접접합되어 5각형 중공박스형태로 구성되고; 경사된 한 쌍의 하판(3A, 3B)속으로 I빔형강(4)이 삽입되어져 I빔형강측면(4A)과 4지점용접접합되어진다.First, as shown in FIG. 1, one
이러한 단면구성방법에서 순차적인 구성실시순서를 예시로 나타내보면 I빔형강측면(4A)에 크레인거더의 처짐 한계비율인 1/800(한국산업안전공단기준)을 적용한 캠버계산결과값으로 제도하고 I빔형강측면(4A)과 한 쌍의 하판(3A, 3B)과 4지점에 용접고정한다.In this cross-sectional configuration method, the sequential construction procedure is shown as an example.The camber calculation result applying I / 800 (Korea Industrial Safety Corporation standard), the limit of deflection of crane girder, to the beam
다른 한편으로는 5각형 중공박스내부에 설치되어지는 다수의 보강판(5)을 하나의 상판(1)에 제도와 용접접합으로 수직취부 후 한 쌍의 측면판(2A, 2B)을 용접접합하여 닫는다.On the other hand, a plurality of reinforcing plates (5) to be installed in the pentagonal hollow box is vertically mounted by drawing and welding on one top plate (1) and then a pair of side plates (2A, 2B) by welding Close it.
상기와 같은 작업이 모두 이루어진 후 전체결합하여 한 쌍의 측면판(2A, 2B)과 경사된 한 쌍의 하판(3A, 3B)을 용접접합시켜 최종취부작업을 완료한다.After all of the above operations are completed, the entire combination is welded to the pair of
또한, 캠버 측정 및 레벨측정 후에 교정작업이 모두 이루어지고 나면 모노레일형 크레인거더가 완성된다.In addition, after the calibration work is completed after the camber measurement and level measurement, the monorail crane girder is completed.
상기와 같이 도 2에서 도시된 바와 같이 3각형 중공단면구성방법의 순차적인 구성실시순서는 도 1에서 도시된 한 쌍의 측면판을 제외한 나머지 순서는 동일하게 이루어진다.As described above, the sequential configuration of the triangular hollow cross-section configuration method as shown in FIG. 2 is the same except for the pair of side plates shown in FIG. 1.
