Abstract

PURPOSE:To efficiently assemble a steel frame with high accuracy by assembling the steel frame with a first roller group to support flanges and a second roller group to adjust a web to the fitted position and welding the web to the contact surface of the flanges. CONSTITUTION:When the web which is temporarily assembled almost in a H-shape and two flanges are sent to an assembling device 3, an inlet side web pressing roller falls to press the web against web rollers 83 and 83a. Next, an outlet side web pressing roller falls and stops so as to provide some clearance between the roller and the web. During this period, the web and the flanges continue to advance and collide against a stopper 129 and the tips of the web and the flanges are put in order. Next, the inlet side web pressing roller rises to press the web and both the flanges against a side roller 96, etc., at the fixed side by a side roller 196a, etc., and the flange pressing rollers at the inlet side and the outlet side and the web pressing roller at the inlet side fall at the same time to press the web and both the flanges. Further, the side roller 196a, etc., are retreated and the flange pressing roller is pressed against the flange roller, etc., to form the complete H-shape.
