It is a system that is used when it is not possible to install curtain formwork on both sides of the curtain, the thickness of the curtain wall is too much to use an anchor shaft and the use of anchors is not suitable. In this system, the concrete pressure coming to the mold is transmitted to the permanent anchors previously placed in the concrete at the ground part of the curtain wall by means of load braces. The single-sided support formwork system to be used according to the height of the curtain wall varies. Dams, retaining walls, insulated curtain walls can be shown as examples of usage areas. They are used when the double surfaces of the curtains cannot be molded.
