[0002] Curtain walls, as building envelopes, are widely used in commercial buildings. Sealing is required at the corners where two vertical curtain wall panels meet. Existing curtain walls often use the corner joint structure disclosed in authorization announcement number CN221143215U. This structure uses an isosceles trapezoidal connector lacking a base, consisting of an upper base and two waists. A fastener is connected to the center of the upper base, and the ends of the two waists furthest from the upper base press against the outer sides of two vertically arranged curtain wall panels.
