Connecting bar (schema)

Tool(s): Coupler, Thread, Connecting Bar

You can use Connecting bar (schema) to apply connecting bars or threads to schema bars. Connecting bars/threads defined using the partial schema are only created for the respective placement. This modified placement gets a new mark number.

To apply connecting bars or threads 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 required manufacturer.
3. Select Connecting bar (schema) on the context toolbar or click OK if this option has already been selected.
4. Use the input options to specify whether the bar segment is to be lengthened or not when the connecting bar/thread is created.
5. Click the end of the schema bar where you want to create the lock nut of the connecting bar or the thread. Requirement: the bar end in question must not have a hook.
6. Click the coupler for which you want to create a connecting bar. The program checks whether the selected coupler matches the diameter of the selected bar. In addition, load type is taken from the coupler clicked when you use the SAH thread bar coupling system.

   The Selection of Articles dialog box opens and you can select a catalog. The connecting bars/thread appropriate to the diameter is/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.

7. Click OK to confirm the Selection of Articles dialog box.

   After having checked the boundary conditions, the program adds symbols representing the lock nut of the connecting bar or the thread to the schema bar and the relevant placement(s), if necessary. With the lengthened option, the relevant bar segment is lengthened by the value specified for the coupler clicked or by the thread length. If the connecting bar/thread 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 lock nut of the connecting bar/thread.
   

   

   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.
