Descrição

The Reinforcement HelicalRebar tool allows the user to create a continuous helical reinforcing bar inside an Arch Structure object.

This tool is part of the Reinforcement Workbench, an external workbench that can be installed with the Addon Manager.

One continuous helical reinforcement bar inside an Arch Structure

Utilização

1. Select any face of a previously created Arch Structure object.
2. Then select Helical Rebar from the rebar tools.
3. A task panel will pop-out on the left side of the screen as shown below.
4. Select the desired orientation.
5. Populate the inputs like 'Left Cover', 'Right Cover', 'Top Cover', 'Bottom Cover', 'Front Cover', 'Bent Angle', 'Bent Factor', 'Rounding' and 'Diameter' of the rebar.
6. Select the mode of distribution either 'Amount' or 'Spacing'.
   • If 'Spacing' is selected, a user can also opt for custom spacing.
7. Pick Selected Face is used to verify or change the face for rebar distribution.
8. Click OK or Apply to generate the rebars.
9. Click Cancel to exit the task panel.

Task panel for the tool

Propriedades

• DadosSide Cover: The distance between rebar to the curved face.
• DadosTop Cover: The distance between rebar from the top face of the structure.
• DadosBottom Cover: The distance between rebar from the bottom face of the structure.
• DadosPitch: The pitch of a helix is the height of one complete helix turn, measured parallel to the axis of the helix.
• DadosDiameter: Diameter of the rebar.

Scripting

See also: Arch API, Reinforcement API and FreeCAD Scripting Basics.

The Reinforcement HelicalRebar tool can be used in macros and from the Python console by using the following function:

Rebar = makeHelicalRebar(s_cover, b_cover, diameter, t_cover, pitch, structure=None, facename=None)

• Creates a Rebar object from the given structure, which is an Arch Structure, and facename, which is a face of that structure.
  • If no structure nor facename are given, it will take the user selected face as input.
• s_cover, b_cover, and t_cover are inner offset distances for the rebar with respect to the faces of the structure. They are respectively the side, bottom, and top offsets.
• diameter is the diameter of the reinforcement spiral inside the structure.
• pitch is the parameter that determines how close or far apart each spiral loop is to each other.

Exemplos

import FreeCAD, Draft, Arch, HelicalRebar

Circle = Draft.makeCircle(radius=250)
Structure = Arch.makeStructure(Circle)
Structure.ViewObject.Transparency = 80
FreeCAD.ActiveDocument.recompute()

Rebar = HelicalRebar.makeHelicalRebar(10, 50, 8, 50, 50, structure, "Face2")

Edition of the rebar

You can change the properties of the rebar with the following function

editHelicalRebar(Rebar, s_cover, b_cover, diameter, t_cover, pitch, structure=None, facename=None)

• Rebar is a previously created HelicalRebar object.
• The other parameters are the same as required by the makeHelicalRebar() function.
• structure and facename may be omitted so that the rebar stays in the original structure.

import HelicalRebar

HelicalRebar.editHelicalRebar(Rebar, 20, 100, 20, 20, 100)
