Abstract (en)
[origin: EP2363549A1] The staircase has prefabricated convergent steps assembled at the level of a central load-bearing wall. Each step has an upper projection (6) that extends between a step deck and a riser part. The wall is constituted of superposition of prefabricated hollow concrete unit elements (2), where each unit element has a notch (5) formed within a side wall (4). The projection is supported at the level of the wall. The notch is shifted from one unit element to the adjacent unit element i.e. upper unit element. The wall receives two bearing reinforcement levels comprising metal bars (10).
