Winding Stairs

Steel Engineering > Stairs/Railings > Industrial staircase

In contrast to straight stairs, winding stairs give rise to straight and skewed stairs

Skewed stairs have a stair start of straight steps in the tread line; the stair start is smaller at the internal stringer and larger at the external stringer. The dimensions change from step to step.

The prerequisite for creating winding stairs is that a sketch for the stairwell contour should exist in the drawing. To create the appropriate sketch, use the Sketch function from the New menu. If the sketch exists, call the Industrial staircase function  and activate the Winding stairs tab.

Proceed as follows:

1. Construct or load the sketch for the stairwell contour.

2. Activate the Industrial staircase function. The Stairs dialogue window is displayed 
3. On the Winding stairs tab, define the stair parameters. These are:
4. the height above datum for the stair start, the stair end and the unfinished floor,
5. the step type
6. the type of stair start and stair end,
7. the stringer and step type,
8. specifications for the stairwell as well as for the rails, stringers and steps.

4. Once you have completed the settings, choose OK to exit the window 
5. Identify the sketch for the stairwell.
6. The possible rise variants for the stairs are displayed. Select the desired variant.
7. Click Fit to generate the stairs .

Notes:

• The Stairs dialogue window is always defaulted with the values that were last specified.
• Winding stairs are fitted as a assembly with the designation (article number) WSTAIRS.
• From Version 2008 on, all fitted stairs will get a special stairs ID, and the stairs data will be saved with the drawing. This enables you to apply subsequent changes to stairs with the Change staircase function whenever you want. The dialogue windows will then be defaulted with the data of the identified stairs.
