Abstract

Cet escalier préfabriqué comprend un limon, sur lequel sont fixés des plateaux de marche (10), lesdits plateaux de marche comprenant une tôle sous marche (11) en acier recevant un plateau béton (12). La tôle métallique dite sous marche (11) est munie sur sa face supérieure, c'est-à-dire sur la face recevant le béton, d'une pluralité de goujons (14), également métalliques, orientés sensiblement perpendiculairement par rapport au plan défini par la tôle sous marche (11), et répartis sensiblement sur toute la surface de ladite tôle. La tôle sous marche (11) est munie au niveau de ses deux extrémités de deux ailes latérales (15), orientées sensiblement perpendiculairement par rapport à la face principale (13) de la tôle, et destinées à assurer le positionnement et la fixation du plateau de marche (10) sur le limon.This prefabricated staircase comprises a stringer, on which are fixed the walking platforms (10), said walking platforms comprising a steel sheet under the step (11) receiving a concrete platform (12). The so-called under-step metal sheet (11) is provided on its upper face, that is to say on the face receiving the concrete, with a plurality of studs (14), also metallic, oriented substantially perpendicular to the plane defined by the sheet under step (11), and distributed substantially over the entire surface of said sheet. The under-step sheet (11) is provided at its two ends with two lateral wings (15), oriented substantially perpendicularly to the main face (13) of the sheet, and intended to ensure the positioning and fixing of the plate walk (10) on the stringer.
