Document Type and Number:
WIPO Patent Application WO/2020/004703
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing and correcting a high-strength beam reinforcing member having a closed section and, more specifically, to a beam reinforcing member manufacturing method, which: improves a conventional beam reinforcing member manufacturing process of manufacturing a profile of a beam reinforcing member by roll forming and then manufacturing a closed section profile through welding; manufactures and corrects a beam reinforcing member, which has a closed section profile formed by using a steel pipe, through a process combined with a process of correction by a profile drawing roll; increases process efficiency; and improves the strength of the beam reinforcing member. The method for manufacturing and correcting a beam reinforcing member having a closed section according to the present invention can use a steel pipe to form a curved closed section, can simplify a beam reinforcing member manufacturing process, and can increase the strength of the beam reinforcing member.
