With the object of providing a stairway that is of light-weight construction and is efficiently produced and constructed and that creates an airy feeling, a stairway is constructed using a pair of lateral girders and steps (12) that are formed by truss structures (10). Each truss structure (10) is composed of an upper chord (1) and a lower chord (2) that are inclined with a stairway gradient, and a plurality of lattice members (4) that connect the upper and lower chords (1, 2). Fixed between the truss structures (10) are a plurality of connecting members (11) that connects them and are horizontally disposed each at the level of the rise, these connecting members (11) having the steps (12) supportively fixed thereto.

L'objet de cette invention est de fournir un escalier ayant une structure légère, construit pour donner toute satisfaction et dont l'aspect est aérien. Pour construire cet escalier, on utilise une paire de poutres et de marches latérales (12) formées par des structures en treillis (10). Chacune de ces structures (10) se compose de deux membrures, supérieure (1) et inférieure (2), inclinées selon un gradient de l'escalier, et de plusieurs pièces d'entrecroisement (4) reliant les deux membrures (1, 2). Entre les structures en treillis (10) se trouvent plusieurs barres de raccordement (11), servant à relier ces structures, et qui sont, chacune, placées au niveau de chaque degré et sur lesquelles sont fixées les marches.
