PREFABRICATED H-BEAM WITH REINFORCED FLANGE INTENSITY

摘要

PURPOSE: A prefabricated H-beam in which flange intensity is reinforced is provided to increase the tensile strength and compressive strength by reinforcing the rigidity of a vertical part. CONSTITUTION: A prefabricated h-beam comprises a horizontal part(610) and a pair of vertical part. The horizontal part is classified into a middle part and two side parts. A pair of vertical parts is upward bent at the two end parts from the end of the horizontal part. The two end parts of the horizontal part and thickness of the vertical part is bent and expanded from when the vertical part is formed in order to make the thickness of the vertical part to thicker than the thickness of the center part of the horizontal part.
