Title: Cold-roll molded lightweight section steel having different thickness cross section
Inventor: KAWABATA YOSUKE
IPC: B21B1/08
Filed: 2019-03-29
Abstract: To provide a cold-roll molded lightweight section steel having a differential thickness cross section which can obtain high efficiency in a cross section, and does not cause the lowering of productivity.SOLUTION: In lightweight section steel having a cross section in which a heavy-thickness plate side (flange) 12 and a thin-thickness plate side (web) 11 continue to each other via a bent part 14, a plate thickness t of the heavy-thickness plate side 12 is homogeneous, and a plate thickness t1 of the thin-thickness plate side 11 is thinly and gradually changed from a terminal point Q of the bent part 14 little by little while having a curvature radius face (plate-thickness gradual change cross section part 11a). When using a web width direction as a strong axial direction, since the web is the thin-thickness plate side, and the flange is the heavy-thickness plate side, a cross section area can be reduced without lowering structure performance. Since the bent part 14 is not abruptly changed to the plate thickness of the thin-thickness plate side from the plate thickness of the heavy-thickness plate side, but mildly changed, roll-molding can be applied to a raw material steel plate having no step part which is not abruptly changed in the plate thickness. In a raw material steel plate having a step part which is abruptly changed in the plate thickness, a variety of kinds of problems occur at roll-molding, however, in this lightweight section steel, such a problem does not occur.SELECTED DRAWING: Figure 1
