STAGE CARRIER FOR IN A PREDETERMINED PLAN FORM COURSE END STAIRS

摘要

Stage carrier for extending in a predetermined plan stairtread, especially for a spiral staircase, with a body (1) from a compact profile carrier material, wherein at least one supporting web (11) and at least a shaped flange (12) are provided; the web (11) has at least one curvature (13), which from a starting point (V`n) on a line of intersection (p) between the plane of the step bearing flange (12) and the plane of the web (11) under a bend (Alpha`n) is formed, its size in relation to the cutting line (p) by Beziehungcot (Alpha`n) = v / is given d`n wherein v is a fixed vertical interval, and d a fixed horizontal projection of the stepped carrier between two starting points (V`n) or between the end of the stage carrier and the first or the last point of departure (V`n), where the starting point (V`n) to the edge of the flange (12) at least one section (2) is performed and a distance (1`n) between adjacent output points (V`n) is given by the developed form of the stepped carrier.
