    • A frame structure for a vehicle body which has a first frame member having a web portion and flanges, which stand from opposite ends of the web portion, a second frame member having a web portion and flanges which stands from opposite ends of the web portion, and a reinforcement having a web portion and flanges, which stands from opposite ends of the web portion. The reinforcement is inserted within the first frame member, and the web portion of the reinforcement is in contact with the web portion of the first frame member. The flanges of the reinforcement are in contact with the flanges of the first frame member, and the edges of the flanges of the second frame member strike against the edges of the flanges of the reinforcement. The flanges of the reinforcement have upper portions and lower portions. The edges of the flanges of the second frame member strike against the edges of the upper portions, and the lower portions of the reinforcement are welded to the flanges of the first frame member. Thus, if the strength required for the frame structure is constant, the thickness of the outer and inner channels can be reduced because of the disposition of the reinforcement.
    • 一种用于车体的框架结构,其具有第一框架构件和第二框架构件,第一框架构件具有腹板部分和从腹板部分的相对端支撑的凸缘,具有腹板部分的第二框架构件和从腹板部分的相对端竖立的凸缘, 以及具有腹板部分和凸缘的加强件,其从腹板部分的相对端站立。 加强件插入第一框架构件内,并且加强件的腹板部分与第一框架构件的腹板部分接触。 加强件的凸缘与第一框架构件的凸缘接触,并且第二框架构件的凸缘的边缘抵靠加强件的凸缘的边缘。 加强件的凸缘具有上部和下部。 第二框架构件的凸缘的边缘抵靠上部的边缘,并且加强件的下部焊接到第一框架构件的凸缘。 因此,如果框架结构所需的强度是恒定的,则由于加强件的布置,外通道和内通道的厚度可以减小。
