Abstract

PURPOSE: To balance the strengths of flat parts and rising part without welding by so continuously forming the frame material from one sheet of plate that the upper flat parts become of two plies and the web portions become of single ply.
CONSTITUTION: A metal plate of a required thickness is continuously formed from one sheet in such a manner that the top and bottom flat parts become of two plies and the web portion 2 being the rising part between these becomes of a single ply, whereby the seamless I-frame body 1 is produced. The seamless constitution enables the process of welding to be saved and enables the quality of the frame material 1 to be improved through the strength balancing of each part.
