Why add extra reinforcement to welded mesh?
For a factory with a mesh welding machine, it's very important that as much of the reinforcement that design think is needed for the element is added to the welded mesh. This will, of course, result in an easier process in the production when the element shall be put together. This article is about how to add reinforcement to the mesh for a FormSlab element.
Production settings
In Standard Admin there is a production setting that will be used when the command check producibility is used.
Figure 1: Check producibility FormSlab
If changes are made to the Reinforcement the Producibility check will be used to check limitations. All not producible bars will be shown in red.
Figure 2: Bar Dimensions in Production settings
The setting Bar Dimension will reduce which possible bar diameters that are available and all other bar diameters will be red if the element is checked.
Figure 3: Directions and definitions
Longitudinal bars always lie parallel to the lattice girders in the tensioning direction.
Figure 4: Production settings intersection points
If the setting only orthogonal bars is set to yes only right-angled bars are allowed.
The setting Welded mesh controls whether the bars should be specified as Rodstock (checked) or Steelmat (unchecked) in the Unitechnik export.
Minimum intersection points mean that the bar needs to be crossed by another bar that many times.
Figure 5: Grid longitudinal
The Grid longitudinal value is the interval of longitudinal bars. The bar is shifted to the nearest grid position. If the grid position is already occupied, the bars are fused together.
Figure 6: Spacing longitudinal
These values if the settings are activated (not in this example) are telling the max and min values for the placement of the longitudinal bars.
Figure 7: Grid transverse
The same setting as the Grid longitudinal value but in the transverse direction.
These modifiers can modify the bars to meet minimum production requirements after they have been cut.
Figure 8: Production modifiers
A: this is for the transverse direction means that the bar is allowed to extend longer than it’s allowed because of a CIM or a hole to meet the criteria needed to produce the mesh in the machine.
This will later on be cut manually in production. This means bars that is longer than “Remove bars shorter than” and Min transversal bar.
B: the distance
C: The same as A above but in the longitudinal direction
D: The same as B above but in the longitudinal direction
E: If two bars are overlapping each other in the transversal direction they will be combined to one bar
F: Same as E above but for longitudinal bars
Note:
Exports can also be made by typing commands in the command box.
New commands for executing exports silent on the current shop drawing.
“-IMP_EXPORT_TO_UNITECHNIK”
“-IMP_EXPORT_TO_BVBS”
“-IMP_EXPORT_TO_PXML”

How to do it
The movie below describes with an example how to get the extra bars into the welded mesh for FormSlabs.
