Abstract
PURPOSE: To manufacture steel material with stiffening ribs with high efficiency, by manufacturing sheet material with ribs by installing projected ribs to sheet materials, and then, by forming the sheet material to a steel materal with stiffening ribs.
CONSTITUTION: A sheet mateial with ribs 1A is obtained by one-piece molding through rolling or by melt-sticking ribs 2 on the upper surfce 1a of the sheet material 1A. A press molding is performed on the sheet material 1A by bending the sheet material 1A at right angles in the direction parallel to the side margin of the sheet material 1A and ribs 2. Then, the sheet material 1A is passed through upper rolls 3, lower rolls 4, and plural pairs of side rolls 5aW5e clamping the sheet material 1A from both sides, and the seaming section is welded with a welding device 6 installed on the upper surface 5f of the final side rolls 5f, and thus, a rectangular steel pipe A, is obtained.
