A stairway forming system (10) includes a plurality of stacked, elongate stair riser form carriers (12-20), the carriers (12- 20) being longitudinally displaceable relative to one another. An anchoring unit (24) anchors at least a lowermost riser form carrier (12) in position relative to a substrate (26). A positioning assembly (28) is attached to at least one of the riser form carriers (12-20) and cooperates with the remaining riser form carriers for displacing the carriers (14-20) in unison relative to one other to adopt a staggered operative configuration approximating an angle of the stairway to be formed.
Un système de formation d'escaliers (10) comprend plusieurs supports de coffrage de contremarches allongés empilés (12-20), lesdits supports (12-20) mobiles longitudinalement les uns par rapport aux autres. Une unité d'ancrage (24) ancre au moins un support de coffrage de contremarche (12) dans une position par rapport à un substrat (26). Un ensemble de positionnement (28) est fixé à au moins un support de coffrage de contremarche (12-20) et coopère avec les supports de coffrage de contremarches restants pour déplacer les supports (14-20) à l'unisson les uns par rapport aux autres de manière à adopter une configuration en quinconce approchant un angle de l'escalier à former.
