Site

Slotted holes

You can define slotted, oversized, or tapped holes.

Option

Description

Default

Forked plate position on bracing

Option Descripton Example

Select the position of the forked plate on the bracing.

This option is useful especially with flat plates.

Cut part B in fork

Define whether the forked part is cut if the bracing rod goes through the forked part. The forked part cut adapts to the bracing rod size.

Tensioner T add to secondary

Select whether the tensioner is added to the secondary part or handled as a loose part and welded to the bracing rod.

  • Yes adds the tensioner to the bracing rod.

  • No welds the tensioner to the bracing rod as a loose part.

Extra tensioners tab

Use the Extra tensioners tab to add extra tensioners. Two different tensioner types can be defined.

Extra tensioners

If there is one bracing, define the tensioner on the Tensioner tab. If there are more bracings, define the tensioners for the second, third, etc. bracing on the Extra tensioners tab. Define the bracing numbers in the Apply on tensioner number box.

The tensioners whose numbers are not entered are created with the properties defined on the Tensioner tab.

For instructions on tensioner bracing dimensions, Cut part B in fork and Tensioner T add to secondary, see the instructions on the Tensioner tab.
