본 발명은 철도차량에 사용되는 알루미늄 구조체의 용접에 관한 것으로, 특히 두께가 과도하게 상이한 부재간의 용접시 사용되는 알루미늄 용접 연결용 부재에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the welding of aluminum structures used in rolling stock, and more particularly, to an aluminum welding connection member used for welding between members with excessively different thicknesses.

종래, 철도차량의 알루미늄 구조체에서, 두께가 과도하게 상이한 알루미늄 부재간을 직접 용접하는 경우에는 응력집중이나 변형 등에 의하여 용접 개소나 그 주변이 변형되는 경우가 발생하였다. Conventionally, in the aluminum structure of a railway vehicle, when directly welding between aluminum members of which thickness differs too much, the welding part or its periphery deforms by stress concentration or deformation | transformation.

최근, 이를 보완하기 위하여 도 4 및 도 5 에 나타내는 바와 같이, 압출되어 이루어지는 알루미늄재의 베이스 판넬 (110) 과, 상기 베이스 판넬 (110) 의 특정 개소에 용접되는 알루미늄 부재 (120) 가 구비되어 있다. 4 and 5, in order to supplement this, the base panel 110 of the aluminum material extruded and the aluminum member 120 welded to the specific location of the said base panel 110 are provided.

상기 베이스 판넬 (110) 은 중공형의 것으로 표면 (111) 은 박판으로 이루어지고, 소정 간격을 두기 위하여 중간에 간재 (112) 가 대각선으로 연속하여 형성되어 있으며, 상기 베이스 판넬 (110) 과 용접되는 알루미늄 부재 (120) 는 두께가 두꺼운 대략 "T"자 형상으로 형성되어 있다.The base panel 110 is a hollow one, the surface 111 is made of a thin plate, the interstitial material 112 is formed diagonally in the middle in order to space a predetermined interval, and is welded to the base panel 110 The aluminum member 120 is formed in the substantially "T" shape which is thick.

한편, 상기 베이스 판넬 (110) 의 용접 부위는 도 5 에 나타내는 확대도와 같이 강도를 확보하기 위하여 두께를 두껍게 압출한 보강부 (113) 로 이루어져 있어, 상기 "T"자형 알루미늄 부재 (120) 와 용접이 이루어질 때, 용접성을 향상시킬 수 있으며, 변형을 방지할 수 있어, 전술한 종래의 문제점을 해결할 수 있었다. On the other hand, the welded portion of the base panel 110 is composed of a reinforcing portion 113 extruded thick in order to secure strength, as shown in the enlarged view shown in FIG. 5, to weld the T-shaped aluminum member 120. When this is done, the weldability can be improved, deformation can be prevented, and the aforementioned conventional problems can be solved.

그러나, 알루미늄재의 압출방식의 특성상 어느 한 방향 예컨대, X 방향만의 두께 조절이 가능하고, 다른 방향 예컨대, Y방향에 대해서는 조절이 불가능하여, 용접이 이루어지지 않는 길이 방향 (Y방향) 전체의 불필요한 부분까지 보강부 (113) 가 형성됨으로써, 베이스 판넬 (110) 의 중량이 증가하게 되어 차량 중량이 증가하는 문제점이 발생하였다. 또한, 보강부 (113) 가 Y방향 전체로 형성됨으로써, 재료 비용이 상승하여 구조체의 제작비용이 증가한다는 문제점도 있었다.However, due to the characteristics of the extrusion method of the aluminum material, it is possible to adjust the thickness in only one direction, for example, the X direction, and impossible to adjust the other direction, for example, the Y direction, so that the entire length direction (Y direction) where welding is not made is unnecessary. Since the reinforcement portion 113 is formed up to the portion, the weight of the base panel 110 is increased, resulting in an increase in vehicle weight. Moreover, since the reinforcement part 113 was formed in the whole Y direction, there existed a problem that material cost rose and manufacturing cost of a structure increased.

본 발명은 전술한 종래기술의 문제점을 해결하기 위해 안출된 것으로, 철도차량의 알루미늄 구조체에 있어서, 과도하게 두께가 상이한 부재간의 용접시에 사용함으로써, 용접 품질향상을 도모할 수 있고, 베이스 판넬의 불필요한 두께 증대를 방지하여 차량의 중량을 겸감시킬 수 있으며, 용접부위의 변형을 방지할 수 있는 알루미늄 용접 연결용 부재를 제공하는 것을 목적으로 한다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and in the aluminum structure of a railway vehicle, the welding quality can be improved by using it at the time of welding between members having excessively different thicknesses. An object of the present invention is to provide an aluminum welding connection member capable of preventing a thickness increase and a vehicle weight, and preventing deformation of a welded portion.

또한, 베이스 판넬의 제작 비용을 저렴하게 할 수 있는 알루미늄 용접 연결용 부재를 제공하는 것을 목적으로 한다.In addition, another object of the present invention is to provide an aluminum welding connection member which can reduce the manufacturing cost of the base panel.

As a result, the material cost can be reduced because the material is not used unnecessarily.

본 발명은 과도하게 두께가 상이한 부재간의 용접시에 알루미늄 용접 연결용 부재를 사용함으로써, 용접 품질향상을 도모할 수 있고, 베이스 판넬(압출재)의 불필요한 두께 증대를 방지하여 차량의 중량을 겸감시킬 수 있으며, 용접부위의 변형을 방지할 수 있다.The present invention can improve the welding quality by using the aluminum welding connection member at the time of welding between members having excessively different thicknesses, and can prevent the unnecessary increase of the thickness of the base panel (extruded material) to allow the weight of the vehicle to be combined. And it can prevent the deformation of the welding part.

또한, 베이스 판넬의 특정 개소에 대한 두께를 조절할 필요가 없어, 용이하고 빠르게 제작할 수 있어, 베이스 판넬의 제작 비용을 낮게 할 수 있다.In addition, it is not necessary to adjust the thickness of a specific part of the base panel, and it is possible to manufacture easily and quickly, thereby lowering the manufacturing cost of the base panel.
