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 a bout how to add reinfocement 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 produciability is used.


Figure 1: Check produciability FormSlab

If changes are made to the Reinforcement the Producability 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 elment 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 are set to yes only right angled bars are allowed.

The setting Welded mesh controls wether the bars should be specified as Rodstock (checked) or Steelmat (unchecked) in the Unitechnik export.

Minimum intersection points means 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

How to do it

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