The invention relates to a stairway, made notably of a wooden material, in which the stair treads are at one end fixed to the masonry and with their other end held by bars fixed to a handrail. To reduce structural complexity, provide a secure support for the stair treads and simplify assembly the invention provides for the stair treads (5) to be fixed at their face ends (5') to shaped iron sections, such as angle iron sections (9) or such like, which are fixed to the masonry, for each of the other face ends (5'') to be supported by at least one bar (4), which bars are fixed in a handrail (1) supported by the floor area (2) and the masonry (3) of a building, and for successive stair treads (5) to be fixedly joined by a riser (13). |
