이러한 본 발명의 차량의 누수방지 루프는 조립시, 도 6에 도시된 바와 같이, 상기 루프패널(100)의 루프패널접합부(110) 상측에 동판(C)을 삽입한 후, 상기 루프패널접합부(110) 하측에 루프사이드아우터패널접합부(210)와 루프사이드인너패널접합부(310)를 순서대로 적층시키고, 상기 루프사이드인너패널접합부(310)의 하측면에 용접건(G)을 접촉시켜 차체내부에서 용접 체결함으로써, 용접시 발생하는용접 체결부위의 변형을 효과적으로 방지하여 용접강도를 향상시키게 된다.When the leakage preventing loop of the vehicle of the present invention is assembled, as shown in Figure 6, after inserting the copper plate (C) on the upper side of the roof panel junction portion 110 of the roof panel 100, the roof panel junction portion ( 110) the roof side outer panel joint portion 210 and the roof side inner panel joint portion 310 are sequentially stacked on the lower side, and the welding gun G is brought into contact with the lower side of the roof side inner panel joint portion 310 to form an interior of the vehicle body. By welding in the welding, it is possible to effectively prevent the deformation of the welding joint generated during welding to improve the welding strength.

이와 같이 하여, 차량의 루프에 루프패널접합부(110), 루프사이드아우터패널접합부(210) 및 루프사이드인너패널접합부(310)의 용접 체결부위를 물이 고이게 되는 루프사이드아우터패널(200)의 고임부(220) 보다 높은 위치로 이동시키고, 상기 용접 체결부위의 내, 외측단부에 각각 씰러(400)를 도포함으로써, 상기 고임부(220)에 고인 물이 차체 내부로 유입되어 발생하는 차체의 부식을 방지하는 동시에, 차체 조립시, 용접 체결부위를 차체 내부에서 동판(C)과 용접건(G)을 이용하여 용접 체결함으로써, 용접 체결시 발생하는 변형을 방지하게 된다.In this way, the weld joints of the roof panel junction 110, the roofside outer panel junction 210, and the roofside inner panel junction 310 are accumulated in the roof of the vehicle. By moving the sealer 400 to a higher position than the pregnant part 220 and applying the sealer 400 to the inner and outer ends of the weld joint part, water accumulated in the stub part 220 flows into the vehicle body, resulting in corrosion of the vehicle body. At the same time, when the vehicle body is assembled, the welding joint is welded using the copper plate C and the welding gun G inside the vehicle body, thereby preventing deformation occurring during the welding joint.

이상과 같은 본 발명은 차량의 루프패널, 루프사이드아우터패널 및 루프사이드인너패널의 접합 체결부위를 차실내에서 용접 체결함으로써 용접부위의 변형을 방지할 수 있어 차량의 용접신뢰성을 향상시킬 수 있으며, 이러한 용접 체결부위를 루프사이드레일에 형성된 고임부보다 높은 위치로 이동시키고 이를 양단에서 씰링함으로써, 루프사이드레일에 고인 물이 차실내로 유입되는 것을 방지하여 차량의 상품성을 증대시킬 수 있는 발명인 것이다.The present invention as described above can prevent the deformation of the welding portion by welding the joint fastening portion of the roof panel, the roof side outer panel and the roof side inner panel of the vehicle in the vehicle interior can improve the welding reliability of the vehicle, By moving the welding fastening portion to a position higher than the ridges formed on the roofside rail and sealing it at both ends, it is an invention that can prevent the water accumulated in the roofside rail from entering the interior of the vehicle and increase the merchandise of the vehicle.
