Assembly type steel frame for curtain wall and its construction method

摘要

PURPOSE: A prefabricated curtain wall steel truss is provided to have no necessity of welding by connecting vertical and horizontal members by assembling binding plates without bolt holes for connecting a horizontal member to a vertical member and to strengthen corrosion-resistance and durability by reducing the damage of a corrosion-resistant member. CONSTITUTION: The prefabricated curtain wall steel truss comprises: a vertical member(100) liquefied and galvanized in an empty square pipe shape; a horizontal member(200) liquefied and galvanized in a long square angle shape having a horizontal plane(210) and a vertical plane(220); a front binding plate(300) composed of a front bending part(310) and a front coupling part(320); a back binding plate(400) composed of a back bending part and a back coupling part; and fixtures(500,500') coupling the front binding plate(300) and the back binding plate(400) or the front binding plate(300) and the horizontal member(200).
