Coupler/end anchorage (schema)

Tool(s): Coupler, Thread, Connecting Bar

You can use Coupler/end anchorage (schema) to apply couplers or end anchorage to schema bars. Couplers defined using the partial schema are only created for the relevant placement. This modified placement gets a new mark number.

To apply couplers or end anchorage to schema bars

1. Click Coupler, Thread, Connecting Bar (How).
   

   Activate Coupler, Thread, Connecting Bar in one of the following ways

   • Menu bar: Create Engineering Bar Reinforcement

   • Palette: Tools Create area in the following module(s):

   Bar Reinforcement

   • Configuration: Engineering Display flyout
2. Select the desired manufacturer.
3. Select Coupler/end anchorage (schema) on the context toolbar and click OK to confirm.
4. Click the end of the schema bar where you want to create a coupler. Requirement: the bar end in question must not have a hook.

   The Selection of Articles dialog box opens and you can select a catalog. All the classes and articles that match the current parameters (e.g. diameter, bending shape) are displayed.
   Clicking a manufacturer in the tree view displays information on this manufacturer in the right pane. Click Options ... to specify whether the Selection name or the Company name is displayed in the tree view.

5. Select the relevant coupler and, in the case of the SAH thread bar coupling system, the load type and click OK to confirm the dialog box .
   

   Available couplers and accessories

   The couplers and accessories that are available to you depend on the selected manufacturer.

   • Couplers and accessories of the SAH thread bar coupling system
   • Couplers of the LENTON rebar splicing system
   • BARTEC screwed-sleeve joints
   • ARMATURIS rebar couplers

   After having checked the boundary conditions, the program shortens the selected bar segment so that the end of the coupler (including accessories, if any) is exactly the same as the original end of the bar. A symbol representing the coupler is added to the schema bar and the relevant placement(s). If the coupler has been applied to the partial schema, a new mark number will be assigned.
   In addition, the label for the schema bar includes information on the coupler type, lock nut and accessories. Furthermore, the changed length of the bar segment is displayed, and the length including coupler and/or coupler body appears in brackets if Label Segment is selected.
   

   

   Checking the boundary conditions

   When couplers, threads and connecting bars are created, the program checks certain boundary conditions. When these conditions are not adhered to, the program displays an appropriate message and does not create the relevant couplers, threads and connecting bars.

   The program checks the following boundary conditions:

   • Minimum distance of coupler or lock nut to bend
   • Distance of bars placed (spacing) for end anchorage and partially for coupler connections.
     The minimum distance must be observed when coupler connections are created. Otherwise, the torque wrench cannot be used.

   Note: The program does not check the edge-to-edge offset and the axial spacing between bars placed individually (single placement) or between neighboring placements!
   Observing these conditions is the responsibility of every individual user.

Note: Whereas the name of the coupling system is always included in schema labels for bars with couplers and/or threads as well as for connecting bars, this information only appears in labels for the placement when the Steel grade parameter is selected.
