A description is given of a screen structure and of a process and an apparatus for the production thereof. The screen structure is distinguished in that it exhibits an anchoring portion which is designed as a concrete protrusion. In this manner, the screen can be mounted with the aid of a simple plug-in connection, whereas complex and time-consuming casting in concrete is dispensed with. In the process, the concrete protrusion is first of all produced on a suitable connection reinforcement, whereafter the connection reinforcement is connected to the principal reinforcement. The screen structure is then cast, the concrete protrusion being integrated. The apparatus comprises a special casting mould which is suitable for casting screens of different lengths.
