の割合は上記範囲内で選ぶべきである。The part that should be on the inside in the bending direction has a plate-shaped part that can be bent in the thickness direction, and the tension side surface of this plate-shaped part is provided with ribs that extend in the length direction. If the ratio of the height of the rib to the thickness of the material is 0.5 to 2, and the ratio of the width of the rib to the width of the plate part is 0.2 to 0.8, the plate When the portion is bent in the thickness direction, the ribs prevent the formation of wrinkles or depressions on the compression side of the plate-like portion. However,
If the ratio of the height of the rib to the thickness of the plate-shaped part is less than 0.5, or if the ratio of the width of the rib to the width of the plate-shaped part is less than 0.2, the above effects cannot be obtained, The ratio of the height of the rib to the thickness of the plate-like part is greater than 2, or
Alternatively, if the ratio of the width of the rib to the width of the plate-like portion is greater than 0.8, the weight of the extruded material becomes large. Therefore, the height of the rib and the ratio of the width of the rib to the width of the plate-like portion should be selected within the above range.
