Abstract: front page image
(EN)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.
(FR)Escalier en colimaçon autoporteur. L'objet de la présente invention est de permettre la construction d'un escalier robuste de ce type, comprenant un petit nombre de composants préfabriqués faciles à adapter aux conditions existantes sur le site de construction, c'est-à-dire à l'espace disponible. Selon la présente invention, l'escalier est construit à partir d'un élément plein vertical (1) qui forme la courbure interne de l'escalier et qui prend appui au sol, d'un certain nombre de barres de support verticales qui forment la courbure externe de l'escalier et qui prennent également appui au sol et de marches (4), disposées en forme d'éventail, qui s'étendent entre l'élément plein et les barres de support, les extrémités desdites marches étant fixées respectivement à l'élément plein et aux barres de support.
