Abstract

The invention concerns a self-supporting spiral stairway. The object of the invention is to allow construction of a sturdy stairway of this kind, comprising a small number of prefabricated components which are easy to adapt to the conditions prevailing on the building site, e.g. to the available space. A stairway in accordance with the invention is constructed from a vertical screen element (1) which forms the inner bend of the stairway, which is curved in the winding direction of the stairway and which is supported on the ground, from a number of vertical supporting rods which form the outer bend of the stairway and which also are supported on the ground, and from treads (4) arranged in a fan-shape and extending between the screen element and the supporting rods with the tread ends anchored respectively in the screen element and in the supporting rods.
