Unitechnik export: Reinforcement tab

Use the Reinforcement tab to control the Unitechnik reinforcement export properties.

You can export single reinforcing bars, groups of straight and bent reinforcing bars, and rectangular or polygonal or bent meshes. The reinforcing bar group, or rectangular or polygonal mesh is divided into several single reinforcing bars. All reinforcing bars are exported in the RODSTOCK block.

Option

Description

Rebars export

When set to Yes , straight reinforcing bars are exported.

Hooks are supported. You can define the setting separately for straight or bent rebars.

When set to Collected , uncollected reinforcement is excluded.

Meshes export

When set to Yes , polygonal or rectangular meshes are exported. Hooks are supported. You can define the setting separately for straight or bent meshes.

You can also select whether to unfold along longest line or parallel to pallet.

Bent reinf. as unfolded

When set to Yes , bent reinforcement is exported as unfolded.

Hooks are also supported for unfolded reinforcement, and you can select Yes, with end hooks. Hooks form 0, 2 and 5 are detected.

Bent meshes with end hooks exports end hook shapes L, S and U (flection form 1, 4 and 5) as terminal hooks according to the Unitechnik specification. Other shapes are exported as free flection forms like before.

Using the option Only meshes , you can export bent meshes as unfolded, while other bent reinforcement is exported as bent.

You can select between two reinforcement starting points: Origin in unfolded rebar or Origin in start rebar point. Origin in unfolded rebar uses the first point of the main leg of rebar or mesh wire depending on the rebar orientation in export. The option also affects the z level of the reinforcement in the resulting Unitechnik file. The start points are unaffected by unfolding options.

Export meshes as

Set the rotation of the mesh plane in the export file. The options are:

Standard

Embeds : Exported as mountparts.

Turned to pallet : All meshes will be individually rotated in line with the pallet axes.

Braced girder classes or names

Enter the class or name of reinforcing bars, steel rods or profiles representing braced girders. For example, 15 17 5 means that parts with class 15, 17, or 5 are considered braced girders. If the Braced girder export and Braced girder classes or names boxes are not used, the braced girders will be exported incorrectly as reinforcement or embeds.

Braced girders are represented as a single line, placed according to your selection:

  • As braced girder top chord (default): The geometry of the main chord (top chord) with all information is included in the export.

  • As braced girder bottom chords : The braced girder is exported as one object but with the quantity number 2 with the spacing included.

  • As braced girder all chords : One object like above but with the quantity number 3.

  • As top chord with end symbols : 2 Mountpart symbols are placed at the top chord end points towards the braced girder direction, line 20 mm long. In addition, the above-mentioned BRGIRDER information.

  • As bottom chords with end symbols : 4 Mountpart symbols are placed at the bottom chord end points towards the braced girder direction, line 20 mm long. In addition, the above-mentioned BRGIRDER information.

  • Only top chord end symbols : 2 Mountpart symbols are placed at the top chord end points towards the braced girder direction, line 20 mm long. No BRGIRDER.

  • Only bottom chord end symbols : 4 Mountpart symbols are placed at the bottom chord end points towards the braced girder direction, line 20 mm long. No BRGIRDER.

Reinforcement export type

Define the structure of the exported file for reinforcement.

Plant with lying robot only

All reinforcement including mesh objects will be exported as individual rodstocks within slabdate.

Fabrication of welded rebars

If Export type is set to Fabrication of welded rebars , bar groups are exported as individual rodstocks, mesh objects are exported as rodstocks within STEELMAT blocks.

The structure of the output file (one SLABDATE is shown only):

 

Collect reinforcement

The structure of the output file is the same as for Fabrication of welded rebars. This option allows you to collect mesh, single reinforcing bars and reinforcing bar groups into groups exported in one STEELMAT block. The groups are collected based on the Collect based on field. You can also collect meshes which belong to different cast units.

1 (orange color): The mesh belongs to the bottom panel of the cast unit, mesh name is MESH1.

2 (blue color): Two single bars, the name is MESH1.

3 (green color): One reinforcing bar group belongs to the top panel, the name is MESH1.

If Reinforcement export type is set to Collect reinforcement and Collect based on is set to Name , all three different reinforcement types are collected into one mesh, which is exported in one STEELMAT block.

Other non-designated rebar groups are exported as individual rodstocks. If the collected mesh has only one rebar, it is exported as an individual rodstock without a STEELMAT.

Collect based on

Select how meshes are collected. Meshes with one bar are exported as a single reinforcing bar.

  • Name

    Meshes, single reinforcing bars and reinforcing bar groups with the same name are collected into meshes. Meshes, single reinforcing bars and reinforcing bar groups with the same name equals one mesh in the exported file.

  • Class

    Meshes, single reinforcing bars and reinforcing bar groups with the same class number are collected into meshes. Meshes, single reinforcing bars and reinforcing bar groups with one class number equal one mesh in the exported file.

  • Grade

    Meshes, single reinforcing bars and reinforcing bar groups with the same grade are collected into meshes.

  • UDA

    Meshes, single reinforcing bars and reinforcing bar groups with the same user-defined attribute are collected into meshes.

    The value you enter in the box next to this option is the UDA value.

Collect if distance is lower then

Define the maximum distance between the mesh rebars to be collected together into one STEELMAT.

Rebar grouping

Group similar rebars with equal spacing. Similar rebars are exported using one RODSTOCK row with correct quantity and spacing. The options are Yes and No (default).

The rebar grouping is primarily intended to be used in the production of simple mesh and reinforcement.

Reinforcing bars length

Select how the reinforcing bar length is calculated.

  • Lines in the middle

  • Lines at the edge (total length only)

  • Lines at the edge (all leg lengths) calculates the lengths of the reinforcing bar legs at the edge of the bars.

  • GetValue(Length) (total length only)

Reinforcing bars diameter

Select how the reinforcing bar diameter is exported. The options are:

This selection affects the results of the Rebar length option.

Rebar direction angle limit

Select whether the reinforcing bars starting direction in XY plane is limited, as required in some production interfaces.

  • No

    The reinforcing bars exported as they're modeled in Tekla Structures.

  • From 0 to 180

    The reinforcing bars are exported so that they have a start angle limit to be under 180 degrees, and therefore always oriented to start in positive pallet y direction.

    In this case the rebar start point will be always be the rebar end with smallest Y-coordinate

  • From 0 to 180 ordered

    Same as above but the reinforcing bars are sorted according to the direction angle of the reinforcing bar: the reinforcing bars with lower angles are first.

  • From 180 to 0 ordered

    The reinforcing bars are sorted according to the direction angle of the reinforcing bar: the reinforcing bars with higher angles are first.

First bending angle

Allows setting the first bending angle of free-flection rodstock to be positive or negative (as required by certain interfaces). The options are:

  • Always positive

  • Allow positive or negative

Reinforcement types

Select the reinforcing bar type in a mesh to be exported.

1 and 2 are for the rods in the bottom face longitudinal and cross bars.

5 and 6 are for the rods in the top face longitudinal and cross bars.

4 is for other rebars placed in the element reinforcement.

8 is for loose bars welded into prefabricated meshes.

Classes for loose rebars type 8

Enter the classes of loose reinforcing bars to be collected. The bars are a part of a mesh and are exported as reinforcing bar type 8.

Classes for non-automated rebars

Enter the classes of reinforcing bars to be tagged for non-automated production.

Spacer type

You can add spacer type information to the first layer of the reinforcement (Unitechnik reinforcement type 1). The spacer type is added to the respective spacer type block in the rodstock within the Unitechnik file. The options are:

Automatic : Calculates the spacer type automatically according to the cover thickness. The cover thickness is divided by 5 and rounded up to the nearest integer. For example, if the cover thickness is 21 - 25 mm, the spacer type is 5, and if it is 26 - 30 mm, the spacer type is 6. Enter the allowed types in the adjacent field, or leave blank to allow any.

User defined spacer type : Enter the spacer type to be input in all first layer rebars.

No : Leaves 0 as spacer type.

Spacer start position

Enter the first spacer start position from the start point of the rebar, for example, 500 (mm).

Spacer pitch

Enter the spacer pitch information from start point onwards, for example, 1000 (mm).

Add mesh stabilizing wires

Select whether to extend reinforcement mesh wires through openings to stabilize the mesh. Use for meshes with large openings.

Stabilization wire max spacing

Enter a value to define the maximum spacing of the wires that stabilize the reinforcement mesh. As a result, the minimum amount of extra wires will be extended within this spacing value from the closest full wire near opening.

Meshes sort

Select whether meshes are sorted.

Meshes offset

Select whether the mesh has an offset defined in the STEELMAT block. If the option is set to Yes , the value for X and Y direction is set to zero. If the option is set to No , the X and Y values are exported according to modeled situation.
