Constraints allow the administrator to specify the standard to be used for the step ladder and the default values. By default, SLH checks to make sure that the default values are between the minimum and maximum values specified in the standard.
The functionality available from the Constraints for Step Ladder part of the Create Defaults window is identical to that available from the Constraints for Stair Flight part of the Create Defaults window. Refer to Stair Flight Constraints for further information.
The Step Ladder part of the Create Defaults window allows the administrator to define the defaults for the step ladder.
|
Top Extension Min |
Input a value in the field to define the minimum top extension distance. |
|
Top Extension Max |
Input a value in the field to define the maximum top extension distance. |
|
Nosing Offset |
Input a value in the field to define the distance between the nose of the tread to the front edge of the stringer. This is measured from the nosing of the treads perpendicular to the front edge of the stringer. |
|
Top Stringer Gap |
Input a value in the field to define the distance for the stringer gap from the selected edge at the top of the step ladder. |
|
Bott Stringer Gap |
Input a value in the field to define the distance for the stringer gap from the selected edge at the bottom of the step ladder. |
|
Stringer Snipe |
Input a value in the field to define the distance for the stringer snipe. |
The Handrail part of the Create Defaults window allows the administrator to define the defaults for the handrail.
|
Top Post Offset |
Input a value in the field to define the distance from the top of the step ladder to the top post. |
|
Max Post spacing |
Input a value in the field to define the maximum distance between the posts. |
|
Post extension |
Input a value in the field to define the post extension distance. |
|
Bend radius |
Input a value in the field to define the bend radius for the exit handrails. |
|
Minimum Exit Height |
Input a value in the field to define the minimum height for the exit handrails. |
|
Exit Extension |
Input a value in the field to define exit handrail extension distance from the edge of the step ladder. |
Allowable Configurations
The Allowable configurations part of the Create Defaults window allows the administrator to define the available configurations for the step ladder.
The administrator can choose from:
-
To plane with top extension
-
To plane with no extensions
-
Top extension
-
No extensions
Use Top
Stringer GapSelect the check box to allow a top stringer gap for to plane with no extensions and no extensions step ladders.
Use Bottom
Stringer GapSelect the check box to allow a bottom stringer gap for top extension and no extensions step ladders.
