PURPOSE:To improve the efficiency of conjoining work on the outer panel of a vehicle body wherein framework members are coupled to each other by a flat coupling plate, by providing the flat coupling plate with through holes in positions corresponding to the coupled portions of the framwork members. CONSTITUTION:A framework member 3 is vertically laid and has such a T- shaped cross section that flanges 12 extend on both the sides of a web 10 extending along the center of the width of the member 3. Another framework member 4 is laid perpendicularly to the framework member 3 and has such a T- shaped cross section that flanges 12 extend on both the sides of a web 11 extending along the center of the width of the member 4. A flat coupling plate 9, which corresponds to the webs 10, 11 of the framework members 3, 4 and couple them to each other, is provided with through holes 18, which are located in positions corresponding to the coupled portion of the framework members and serve for the sake of coupling tools 17. According to this constitution, the coupling tools 17 are allowed to have a straight form, and do not need to be rotated even if the coupled portions 5-8 of the framework members 3, 4 are sequentially coupled to each other. |
