Description

The Column Reinforcement tool allows the user to create reinforcing bars inside a Column Arch Structure object.

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

Column Reinforcement inside a Column Arch Structure

How to use

1. Select any face of a previously created Arch Structure object.
2. Then select Column Reinforcement from the rebar tools.
3. A dialog box will pop-out on screen as shown below.

Properties

Ties:

  • DataLeft Cover: The distance between the left end of the tie to the left face of the structure.
  • DataRight Cover: The distance between the right end of the tie to right face of the structure.
  • DataTop Cover: The distance between tie from the top face of the structure.
  • DataBottom Cover: The distance between tie from the bottom face of the structure.
  • DataOffset: The distance between tie and selected face.
  • DataNumber: The number of ties.
  • DataSpacing: The distance between the axes of each tie.

Tie1:

  • DataDiameter: Diameter of the tie1.
  • DataBent Angle: Bent angle defines the angle at the ends of a tie1.
  • DataExtension Factor: Extension Factor defines length of end of tie1.

Main Rebars: Rebars present at corners of tie

  • DataRebar Type: Type of main rebars.
  • DataHook Orientation: Orientation of LShaped hooks.
  • DataHook Extend Along: Direction for hook extension.


Scripting

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

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

Rebar = makeStraightRebar(f_cover, coverAlong, rt_cover, lb_cover,
                          diameter, amount_spacing_check, amount_spacing_value, orientation="Horizontal",
                          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.
  • f_cover, coverAlong, rt_cover, and lb_cover are inner offset distances for the rebar elements with respect to the faces of the structure.
    • f_cover is the frontal cover offset.
    • coverAlong is a tuple (position, value) that defines the offset value in one position (top, bottom, left, right) depending on the orientation.
    • rt_cover is either the right or the top cover offset, depending on the value of coverAlong and orientation.
    • lb_cover is either the left or the bottom cover offset, depending on the value of coverAlong and orientation.
  • diameter is the diameter of the reinforcement bars inside the structure.
  • amount_spacing_check if it is True it will create as many reinforcement bars as given by amount_spacing_value; if it is False it will create reinforcement bars separated by the numerical value of amount_spacing_value.
  • amount_spacing_value specifies the number of reinforcement bars, or the value of the separation between them, depending on amount_spacing_check.
  • orientation specifies the orientation of the rebar; it can be "Horizontal" or "Vertical".

Depending on the orientation of the rebar, the function can be called in two general ways by setting coverAlong appropriately.

The rebar is horizontal

Rebar = makeStraightRebar(f_cover, ("Top Side", value), right_cover, left_cover, ...)
Rebar = makeStraightRebar(f_cover, ("Bottom Side", value), right_cover, left_cover, ...)
  • coverAlong is a tuple with either a "Top Side" or a "Bottom Side" offset value.
  • In this case rt_cover refers to the right_cover offset, and lb_cover refers to the left_cover offset.

The rebar is vertical

Rebar = makeStraightRebar(f_cover, ("Left Side", value), top_cover, bottom_cover, ...)
Rebar = makeStraightRebar(f_cover, ("Right Side", value), top_cover, bottom_cover, ...)
  • coverAlong is a tuple with either a "Left Side" or a "Right Side" offset value.
  • In this case rt_cover refers to the top_cover offset, and lb_cover refers to the bottom_cover offset.

Example horizontal

import Arch, Draft, StraightRebar

Structure = Arch.makeStructure(length=1000, width=1000, height=400)
Structure.ViewObject.Transparency = 80
FreeCAD.ActiveDocument.recompute()

Rebar = StraightRebar.makeStraightRebar(50, ("Bottom Side", 20), 100, 100,
                                        12, True, 5, "Horizontal", Structure, "Face4")
Rebar.ViewObject.ShapeColor = (0.9, 0.0, 0.0)

Rebar2 = StraightRebar.makeStraightRebar(50, ("Bottom Side", 50), 100, 100,
                                         12, True, 5, "Horizontal", Structure, "Face6")
Rebar2.ViewObject.ShapeColor = (0.0, 0.0, 0.9)

Example vertical

import Arch, Draft, StraightRebar

Structure2 = Arch.makeStructure(length=1000, width=1000, height=400)
Structure2.ViewObject.Transparency = 80
Draft.move(Structure2, FreeCAD.Vector(1500, 0, 0))
FreeCAD.ActiveDocument.recompute()

Rebar3 = StraightRebar.makeStraightRebar(50, ("Left Side", 20), 100, 100,
                                         12, True, 5, "Vertical", Structure2, "Face4")
Rebar3.ViewObject.ShapeColor = (0.9, 0.5, 0.0)

Rebar4 = StraightRebar.makeStraightRebar(50, ("Left Side", 50), 100, 100,
                                         12, True, 5, "Vertical", Structure2, "Face6")
Rebar4.ViewObject.ShapeColor = (0.0, 0.5, 0.5)

Edition of rebar

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

editStraightRebar(Rebar, f_cover, coverAlong, rt_cover, lb_cover,
                  diameter, amount_spacing_check, amount_spacing_value, orientation,
                  structure=None, facename=None)
  • Rebar is a previously created StraightRebar object.
  • The other parameters are the same as required by the makeStraightRebar() function.
  • structure and facename may be omitted so that the rebar stays in the original structure.

Example:

import StraightRebar

StraightRebar.editStraightRebar(Rebar, 50, ("Top Side", 20), 100, 100,
                                24, True, 7, "Horizontal")

StraightRebar.editStraightRebar(Rebar2, 50, ("Top Side", 50), 100, 100,
                                24, True, 7, "Horizontal")

StraightRebar.editStraightRebar(Rebar3, 50, ("Right Side", 20), 100, 100,
                                24, True, 7, "Vertical")

StraightRebar.editStraightRebar(Rebar4, 50, ("Right Side", 50), 100, 100,
                                24, True, 7, "Vertical")
