The invention relates to a device permitting the production of a stairway step without any special tooling equipment. It comprises a prefabricated reinforced concrete module 11 representing, in one piece, the nosing 12 of the step and the riser 1. A horizontal face 2 and a vertical face 3 delimit the nosing. A mould 4 connects the face 1 and the face 2. A quadrant 5 is situated between the vertical plane 3 and the vertical plane 6 followed by the horizontal plane 7. The slope 8 follows, then a vertical plane 9, and finally a horizontal plane 10. This module comprises fastening irons permitting the connection of the cast concrete, which are associated with the reinforcement network of the module. This device according to the invention is intended in particular for the production of a stairway step. <IMAGE>
