The invented device for swinging gaebangsik wall building outer wall is directed to a device that is opened to swing structure forms the walls of buildings, is provided between the pillars and the pillars of the building frame having a fixed upper beam and a left / right side beam; Swing wall is provided inside of the holding frame which forms a wall surface and swing up and down; The fixed frame and is disposed between the right and left opposite sides of the swing wall, one side is linked to the coupling side coupled to the other so as to rotate on the fixed frame side so as to rotate the swing wall is the wall to swing the swing; A swing block coupled to the pivot joint of the bottom side wall of the swing link; Lifting shaft for moving the swing block up and down in conjunction downward perpendicular to the swing block; And a lifting driver to lift the axis moves up and down in conjunction with the lift shaft; there is an effect that it is possible to open the whole wall so that the function of carrying out at the same time the internal space as a general building wall and characterized in that it includes an open space . In addition, there is an effect that it is possible to completely open the opening portion, it is possible to control the degree of opening of the opening portion, the to maintain the controlled state a stable effect, and structurally stable and easily broken by an external force acting from the outside to the effect that a failure does not occur.
