Stair Railings - Parameters (3-D SE)

Use the following tabs to set the parameters for stair railings:

Handrail + Posts
Infill
Mounting position

Once you have made all required parameter specifications, exit the window with OK. Identify one of the stringer sections of the staircase to fit the railing.

For stairs with railings on both sides you create a main part called RAILING, with two sub-parts, RAILING RIGHT and RAILING LEFT, for stairs with railings on only one side you create a main part with one sub-part RAILING LEFT or RAILING RIGHT, respectively.

Example

Handrail + Posts

In this tab you set the parameters for handrail and posts of the railing.

The railing can either be created on the external side of the staircase or on both sides, depending on the selected symbol .

Handrail

Select the desired handrail type from the listbox.
Specify the required dimensions by clicking the button above the listbox.
If required, change the railing height HR.

Posts

Select the post type from the appropriate list box, then specify the dimensions via the button above the list box.
If required, change

the maximum distance between the post, PMax
the distance "first post<-> step" DXPA,
the distance "last post<-> step" DXPE.

If you want to trim the post to the handrail, activate the appropriate checkbox. If the checkbox is active, the cut will be adapted accordingly, otherwise the cut will be straight.

Start/End

Select the handrail type at the beginning and the end by clicking the appropriate icon. Depending on the type, you can then select the design of the pipe bend. The values DXA and DXE determine the excess length of the handrail at the beginning and the end.

Infill

This tab allows you to define the parameters for booms,rods and knee rails of the railing. Which of the input fields are active depends on the selected railing type. The following options are available:

railing with lower boom,
railing with lower and upper boom,
railing with knee rails.

You select the desired type by activating the appropriate icons .

After selecting the railing type the preview image is updated accordingly, and the default values for the railing data are shown in the input fields.

Boom

Select the required type from the appropriate list box, then specify the dimensions by clicking the button above the list box.
If required, change

the distance "lower boom <-> floor " DXU and
the distance"upper boom<-> handrail " DXO .

If you want to trim the boom to the handrail, activate the appropriate checkbox. If the checkbox is active, the cut will be adapted accordingly, otherwise it will be straight.

Rod

Select the required type from the appropriate list box, then specify the dimensions by clicking the button above the list box.
If required, change the maximum fill spacing FMAX.
If you want to trim the rod to the handrail, activate the appropriate checkbox. If the checkbox is active, the cutting will be adapted accordingly, otherwise it will be straight.

Knee rail

Select the required type from the appropriate list box, then specify the dimensions by clicking the button above the list box.
Select the number of knee rails.
If you want to trim the knee rail to the post, activate the appropriate checkbox. If the checkbox is active, the cut will be adapted accordingly, otherwise it will be straight.
Specify the data for the bores on the post.

Proceed likewise to specify the data for the skirting.

Mounting position

Top/Lateral	Activate the corresponding checkbox to define whether you want the railing to be top-mounted on the upper edge of the stringer (top) or front-mounted on the side of the stringer (lateral). For stringers that do not have a flange (e.g. wide flat steels), only a lateral mounting will be possible. Therefore the selection options are deactivated in such cases.
With base plate	Activate the With base plate checkbox if you want the railing to be fitted with a base plate. Which of the input fields are active depends on the selected base plate type. The parameter specifications will be displayed in the preview graphic
Base plate	If you have activated the With base plate checkbox, specify the data for the base plate. Which input fields are active depends on the selected base plate form. The meaning of the parameters can be seen by a corresponding preview graphic. Select the desired base plate form. Enter the desired dimensions for the plate.
Distance plate	If you have activated the With base plate and selected the lateral mounting type, you can additionally insert a distance plate. Activate the corresponding checkbox and specify the data for the plate.
Bolting	If you have activated the With base plate checkbox, you can specify the bolting here. The boltings that are available for the railings care defined in the file Railing Screw Joint.ini (in the HiCAD subdirectory KATALOGE\SYS\CONFIGS). Predefined are configurations for bolts of the type DIN 7990 and a strength of 5.6, with a flat washer, a wedge disc 5%, a wedge disc 8%, and a wedge disc 14%. bolts of the type DIN EN 14399-4 and a strength of 10.9, with a flat washer, a wedge disc 5% and a wedge disc 8%. To change these default configurations, activate the 3-D Standard tab and select Standard Parts > New bolting . In the selection box, all valid bolting configurations from the file Railing Screw Joint.ini are displayed. Valid are configurations with a common nominal diameter for all bolting elements (bolt, washer, nut, bore), and a washer /wedge disc on the nut's side with the inclination of the flange of the stair stringer. A further selection box for the last chosen valid configuration will be initialised, with all valid nominal diameters. Valid are all nominal diameters which apply to all elements of the configuration. If the configuration file does not exist, cannot be read, or does not contain a valid configuration, the Bolting selection box will be inactive, and the text Without bolting will be displayed. When you close the dialogue with OK, the message No valid bolting exists! will be shown, and the query Create railing without boltings? appears. If you answer Yes, the dialogue will be closed and the railing will be created without boltings. If you select No, the dialogue will not be closed. You can then either change the settings or end the dialogue with Cancel.
