Abstract
PURPOSE: To reduce the man-hour of welding, and to fabricate titled box type structure in which the generation of strain is reduced, by forming through the press work the U-type member for the straight zone and two L-type members for the curved zone, and by combining these members on a curved flat plate, and then, by welding these members together with.
CONSTITUTION: The bottom sheet 1 is bent at a specified bending radius, and a U- type press work is carried out to form U-type members 2, 3, into a specified construction; thus obtained U-type members 2, 3, are applied to the straight zone later. In the meantime, for the curved zone, L-type members 4, 5, are formed by the press machine, and then, the end part of the curved edge is cut by automatic gas cutting; hereby, the dimensional accuracy of L-type members can be secured. Next, members 4, 5, are combined to form U-type, and the joint portions of them together with respective other members 1, 2, 3, are welded; hereby, a curved box type structure is obtained; in this box type structure, the joint portions between the curved zone and straight zone are made the same shape, so that the stress concentration is reduced, and the improvement of strength can be contrived.
