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.

Its also possible to add longitudinal bars at mesh ends and mesh cut outs - The bars will be inserted according to the Grid longitudinal value and end overshoot value for the mesh.

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.

Figure 8: Spacing transverse

The same setting as the Spacing longitudinal but in the transverse direction.

Figure 9: Setting to move bars automatic

Move from small holes and cims is a function that test if it possible to move the reinforcement a certain distance without needing to cut them (se picture above). If it's not possible to move the reinforcement with the grid and the within the certain distance the bar will keep its distance and it will be cut instead.

Figure 10: Description of move from small holes and cim

The function will only be in play if we the hole or cast in material has a setting to cut the bar. IMPACT will move the bar to the right if possible - If that isn't possible then will IMPACT move it to the left.

Figure 11: Setting to cut bar/mesh for holes

Figure 12: Setting to cut bar/mesh for cast in materials

These modifiers can modify the bars to meet minimum production requirements after they have been cut.

Figure 13: 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.

Figure 14: Transverse direction at a CIM

This will later on be cut manually in production. This means bars that is longer than “Remove bars shorter than” and Min transversal bar.

Figure 15: Remove and min transverse settings

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

Figure 16: Mesh length

Mesh length sets the minimum and maximum length for each mesh. If the mesh in the element exceed the max length will there be inserted a second mesh with a gab to the first mesh.

Override rules when exceeding max length changes the minimum and maximum length values if the max length is exceeded.

Figure 17: Mesh width

Mesh width sets the minimum and maximum width for each mesh. If the mesh in the element exceed the max width will there be inserted a second mesh with a gab to the first mesh.

Swap rules for length/width when exceeding max width does that the minimum and maximum width takes a reference in the minimum and maximum length and vise versa.

Figure 18: Mesh mass

Sets the max mass for each mesh.

Bended mesh settings

In Q1/2024 are there added more rules when producing bent meshes.

Under the "General Settings" are there added a new option called "Bended Mesh" - If this setting is enabled will it be possible to set 5 general rules for the bent mesh.

The first rule is "Max number of bends per bar end". As the picture below shows is it possible to have 4 bends. Setting the "max number of bends per bar end" sets the rules for how many bends are allowed. 

The Second rule "Reject overlapping bends" sets if the length of the second bend is allowed to overlap each other.

The third rule "Reject overlapping outer corner" sets if the bent bars are allowed to overlap in the elements' outer corners. 

The fourth rule "Reject overlapping inner corner" sets if the bent bars are allowed to overlap in the elements' inner corners at openings and recesses.  

The fifth and last rule is "Min gap between opposing bar ends". This sets the minimum distance between the bars before they are bent. Configuring this makes sure that none of the bars clash before they are bent.

Under the "Bar Dimensions" is there added "Bending" for all the dimensions - This will make it possible to make a specific set of bending rules for each dimension.

Under the bending rules for each dimension is it possible to define minimum and maximum values for each jig radius (Bending die radius) in the specific dimension. It's important that one Radius is marked with the "Default Value".

1) A - Radius = This is the Bending die radius used in the bar mesh machine - This value needs to be unique.
2) Default = Sets the default Bending die radius for the selected reinforcement dimension. The default bending die radius is used for the automatic bending with endcaps, and it’s also used in the command “Bend Bars...” as a default value which can be changed through a dropdown with all available bending die radiuses for the current bar diameter. 
3) B - Min = The Minimum distance of the first bend.
4) B - Max = The Maximum distance of the first bend.
5) C - Min = The Minimum distance of the second bend.
6) C - Max = The Maximum distance of the second bend.
7) D - Min = The Minimum distance of the third bend.
8) D - Max = The Maximum distance of the third bend.
9) E - Min = The Minimum distance of the fourth bend.
10) E - Max = The Maximum distance of the fourth bend.
11) Max Flying End -  The Max projection for the specific radius.
12) F - Min = Minimum distance from the middle of the die to the edge of the nearest parallel bar.
13) G - Min = Minimum distance to nearest parallel bar, "Closed side with thread in"
14) H - Min = Minimum distance bending die to the nearest crossbar “Front"
15) I - Min = Minimum distance bending die to the nearest crossbar "Back"

In AutoCAD is it possible to choose the bending radius for the "Bending die" and get the rules applied.
