Abstract (en)
The formwork consists of standardisable modules each corresponding to a step grouping together all the surfaces which may be produced using formwork or only the selected ones. They may include a finished step surface which can be placed at the time of pouring the concrete. The same modules can be made to fit all heights of stairs and, in a version in separate parts, several widths. Special modules are available for forming circular or helicoid shapes. These modules remain incorporated in the stairs and constitute the finishing thereof. <IMAGE>
