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.

Scripting

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

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

RebarGroup = makeSingleTieFourRebars(l_cover_of_tie, r_cover_of_tie, t_cover_of_tie, b_cover_of_tie, offset_of_tie, bent_angle,
                                     extension_factor, dia_of_tie, number_spacing_check, number_spacing_value, dia_of_rebars,
                                     t_offset_of_rebars, b_offset_of_rebars, rebar_type="StraightRebar",
                                     hook_orientation="Top Inside", hook_extend_along="x-axis", l_rebar_rounding=None,
                                     hook_extension=None, structure=None, facename=None)
  • Creates a RebarGroup 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.
  • l_cover_of_tie, r_cover_of_tie, t_cover_of_tie, b_cover_of_tie and offset_of_tie are inner offset distances for the tie elements with respect to the faces of the structure. They are respectively the left, right, top, bottom and front/rear offsets.
  • bent_angle define the angle of the tip of the reinforcement loop.
  • extension_factor define the length of the tip of the reinforcement loop, expressed in times the diameter.
  • dia_of_tie is the diameter of the ties.
  • number_spacing_check if it is True it will create as many ties as given by number_spacing_value; if it is False it will create ties separated by the numerical value of number_spacing_value.
  • number_spacing_value specifies the number of ties, or the value of the separation between them, depending on number_spacing_check.
  • dia_of_rebars is the diameter of the main rebars.
  • t_offset_of_rebars and b_offset_of_rebars are inner offset distances for the main rebars with respect to the top and bottom faces of the structure, respectively.
  • rebar_type is the type of the main rebars; it can be "StraightRebar" or "LShapeRebar".
  • hook_orientation specifies the orientation of LShaped hook; it can be: "Top Inside", "Top Outside", "Bottom Inside", "Bottom Outside", "Top Right", "Top Left", "Bottom Right" or "Bottom Left".
  • hook_extend_along specifies direction for hook extension; it can be "x-axis" or "y-axis".
  • l_rebar_rounding is the parameter that determines the bending radius of the LShaped main rebars, expressed as times the diameter.
  • hook_extension is the length of hook of LShaped rebars.


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")
