Описание

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

The Helical Rebar tool is also integrated into BIM Workbench.

This command is part of the Reinforcement Workbench, an external workbench that can be installed with the AddonManager.svg Addon Manager via the Tools → Addon manager → Reinforcement menu.

Применение

  1. Select any face of a previously created Arch Structure.svg Arch Structure object.
  2. Then select Arch Rebar Helical.svg 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'.
  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.

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.

Пример

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)
