PURPOSE: A method for forming curved shape steels using a corrugated member is provided to accurately and rapidly cope with the radius variation of curvatures and thickness variation on metal by-products used for atypical buildings. CONSTITUTION: A method for forming curved shape steels using a corrugated member is as follows: a step of calculating the control values of multiple pushing pieces mounted on a molding part (S10); a step of corrugating raw materials selected from rod steel, a pipe, C-shaped steel (S20); a step of elongating the corrugated materials from a stretching part to a yield point (S30); a step of forming the elongated materials to finished products having a curved surface set in the molding part (S40); and a step of determining whether or not the finished products are in an error range (S50); and a step of inputting a calibration value when the finished products are not in the error range. [Reference numerals] (AA) Yes; (BB) No; (CC) Complete; (S10) Multi-point control value calculation; (S20) Raw material corrugating process; (S30) Stretching-forming; (S40) Pressing-forming; (S50) Within an error range of a finished product?; (S60) Correction value input |
