PURPOSE:To easily and surely perform the installation work of a reinforcement plate to a frame, by installing the reinforcement plate in such a method that slender slits are provided in the reinforcement plate and the slits and the frame are welded. CONSTITUTION:Laterally slender slits 9 about 1cm in width are provided in a reinforcement plate 1. The reinforcement plate 1 with the slits 9 is placed on a frame 8. Then the slits 9 and the frame 8 are welded and jointed while filling up concaves of the slits 9. And contact points 10 of the other reinforcement plate 1 and the frame 8 are sporadically welded. In this way, a uniform thickness of the frame 8 and the reinforcement plate 1 can be obtained without causing a distortion due to the work of welding, resulting in the improvement of strength. |
