Описание

Инструмент Helical Rebar позволяет пользователю создавать в структурном элементе арматурный стержень с изогнутой формой.

This command is part of the Reinforcement Addon, that you can install with the Addon Manager, via the menu Tools → Addon manager → Reinforcement.

Использование

  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. Give the inputs like front cover, right side cover, left side cover, bottom cover and diameter of the rebar.
  6. Select the mode of distribution either amount or spacing.
  7. If spacing is selected, a user can also opt for custom spacing.
  8. Pick selected face is used to verify or change the face for rebar distribution.
  9. Click OK or Apply to generate the rebars.
  10. Click Cancel to exit the task panel.

Свойства

  • ДанныеSide Cover: The distance between rebar to the curved face.
  • ДанныеTop Cover: The distance between rebar from the top face of the structure.
  • ДанныеBottom Cover: The distance between rebar from the bottom face of the structure.
  • ДанныеPitch: The pitch of a helix is the height of one complete helix turn, measured parallel to the axis of the helix.
  • ДанныеDiameter: Diameter of the rebar.

Сценарии

The Helical Rebar 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.

Example

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)
