<p>PURPOSE: A curtain wall system using a roll-forming frame and a steel flat bar is provided to improve the constructionability manufacturability, and the external appearance of the curtain wall and to have sufficient rigidity by using a roll-forming frame with high rigidity. CONSTITUTION: A curtain wall system using a roll-forming frame and a steel flat bar comprises a horizontal frame(20), a vertical frame(30), a steel flat bar(40), and connecting members(70A,70B). The vertical frame is perpendicularly combined with the horizontal frame; integrally roll-formed to a steel material; combined with a glass supporting unit for supporting a glass structure(10). The steel flat bar is combined in the vertical frame in order to reinforce the vertical frame. The connecting members are equipped on both sides of the vertical frame to combine the horizontal frame with each vertical frame.</p> |
