OUTER PLATE REINFORCING METHOD FOR VEHICLE AND BODY STRUCTURE USING THIS METHOD

摘要

PROBLEM TO BE SOLVED: To reduce the weight of a device, to lower the cost, and to enable the sufficient strength by putting a corrugate plate on the inner surface of an outer plate along over the whole surface for integral connection. SOLUTION: In a side groove body A1, a metal corrugate plate 2 is put on the inner surface of a metal outer plate 1 along over the whole surface for integral connection so as to reinforce the outer plate 1. The outer plate 1 and the corrugate plate 2 are connected to each other by spot welding or the like. Both the outer plate 1 and the corrugate plate 2 are formed of a stainless steel plate capable of formed thinner than an aluminum base plate in consideration of strength and weight reduction. The corrugate plate 2 formed with continuous recessed parts 2a and projecting parts 2b in the longitudinal direction of a vehicle is used for a wainscot panel part A1a and a frieze board A1b of a side groove body A1, sand the corrugate plate 2 formed with continuous recessed parts 2a and projecting parts 2b in a direction at a right angle against the longitudinal direction of the vehicle is used for a part A1c between openings 7a, 8a of an window 7 and an entrance 8 of the side groove body A1 and between the wainscot panel part A1a and the frieze board part A1b.
