PURPOSE: A coupling structure of a steel curtain wall is provided to shorten a period of construction by assembling a curtain wall easily in a high-rise building, to insulate thermally or to prevent a water leakage by increasing the airtightness of pair glass, to cut down the cost by forming a vertical frame and a horizontal frame with steel, to prevent the absorption of horizontal displacement and interlayer displacement by wind and earthquake, and to have decorative effect and to harmonize with the surroundings by improving the appearance of a vertical frame. CONSTITUTION: In a coupling structure of a steel curtain wall, a dovetail groove(111) is formed longitudinally in the center of a fixing plate(110) at the front of a steel frame(10), a ∩v-shaped wedge piece(40) is inserted to the dovetail groove, an inner gasket(50) is provided to two fixing plates of the dovetail groove, an outer gasket(60) corresponded to the inner gasket is provided to the inside of a bracket(20), and the edges of pair glass(G) are placed face to face between the inner gasket and the outer gasket to couple a washer bolt(30) to the wedge piece inserted to the dovetail groove of the steel frame on the outside of the bracket.
