Abstract

PURPOSE: A method for constructing the cross section of a monorail-type crane girder is provided to eliminate an unnecessary space and to improve safety and work efficiency because a fastening work is not required. CONSTITUTION: A method for constructing the cross section of a monorail-type crane girder is as follows. A top plate(1) is vertically welded in a pair of side plates(2A,2B). The vertical side plates are inclinedly welded in a pair of bottom plates(3A,3B) in order to form a pentagonal hollow box shape. An I-beam girder(4) is inserted between the inclined bottom plates in order to complete the cross section of a crane girder.

Description

모노레일형 크레인거더의 단면구성방법{Section Structure Method of Monorail Type Crane Girder}Section Structure Method of Monorail Type Crane Girder

본 발명은 운반물류기계인 크레인 분야에 관한 것으로서 특히 모노레일형 크레인 거더의 단면구성방법에 관한 것이다.TECHNICAL FIELD The present invention relates to the field of cranes, which are conveying logistics machines, and more particularly to a cross-sectional configuration method of a monorail crane girder.

일반적으로 모노레일형 크레인거더의 단면구성은 도 3에서 도시된 바와 같이사다리꼴 모양으로 된 하나의 상판(31)과; 하나의 하판(33)과; 한 쌍의 측면판(32A, 32B)으로서; 4각형 중공박스형태로 용접접합 또는 절곡하였고 그 아래에 하나의 하판(33)하부와 I빔형강(34)상부의 접촉지점에 2지점 용접접합되어 완성된 전체의 크레인거더로 이루어진다.In general, the cross-sectional configuration of the monorail crane girder is one top plate 31 of the trapezoidal shape as shown in Figure 3; One lower plate 33; As a pair of side plates 32A and 32B; Welded or bent in the form of a quadrangular hollow box, it consists of a whole crane girder completed by two points welded to the contact point of the bottom of one lower plate 33 and the upper portion of the I-beam steel 34.

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 lower plate 33 and the upper portion of the I-beam steel 34 have a two-point welded joint together with a bolt and nut fastening at the risk machine safety certification examination. Recommended.

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-beam steel 34.

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-beam steel 34, and to fix the welding fixation at two points. To increase the point to provide safety and work efficiency.

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 lower plates 3A, 3B, 23A, 23B; As a pair of side plates 2A and 2B; Welded in the form of a pentagonal or triangular hollow box, and under the pair of lower plates 3A and 3B, the I beam steels 4 and 24 are inserted upwards and the I beam steel sides 4A and 24A. The pair of lower plates 3A, 3B, 23A, 23B; It is completed to be joined to 4 points and used as crane girder.

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-beam steels 4 and 24 are inserted into the pair of lower plates 3A, 3B, 23A, and 23B to be welded and fixed at four points, bolt and nut fastening operations are excluded, thereby improving work efficiency. And increased safety due to the increased cross-sectional area from the vertical loads coming from below the floor.
