Medeek Floor

[medeek]

Adding in the advanced floor options into the Global Settings:

I am working on adding in metal bridging with some associated parameters:

P.S.
I was going to combine the metal bridging with the solid blocking however after some thought I realized there might be cases where you might combine both forms of bracing in one floor (solid blocking and metal bridging). Hence I need a separate module for blocking. Unlike the wall blocking floor blocking may be regular lumber or I-Joist blocking so that further complicates the matter slightly.

The parameters for the blocking module will probably be:

1.) Blocking Type: Lumber/I-Joist

If blocking type is Lumber:

Blocking Width: 1.5 in (default)

Blocking Material: Lumber / PT Lumber / LSL / PSL / LVL etc...

If blocking type is I-Joist

Blocking I-Joist Family:

Blocking I-Joist Type:

other general parameters are:

Row Spacing: 96 in. (default)

Stagger Blocking: Yes/No

Remove Row: empty by default

Quite a few more parameters (8) to add into a number of files, this will keep me busy for a couple of days at least.

First look at metal bridging (I-joist and Lumber):

Geometrically a lot simpler and more lightweight than the preconfigured component that I made based off of the Simpson IFC model. I'm using my galvanized texture/material but I may change it slightly. There are quite a few parameters that one can adjust to customize the look and feel of these metal bridging straps, hopefully that should make things configurable enough for most power users.

As noted per the Simpson literature the crossing straps should not be in direct contact to avoid screeching noises when they move under load. Hence the default 1/8" gap, but this can be modified as can be seen in the menu.

I've also included a thickness parameter for the straps. The correct thickness for a 20 gauge strap is probably around 0.035" however I've rounded the default value to an even 0.04".

Version 0.9.8 - 09.27.2024

• Made the polyline/face icon (draw mode) in the draw menu clickable.
• Added a joist direction toggle button/icon to the draw and edit menus.
• Added a stagger joist option to the Draw and Edit menus.
• Updated the insulation, blocking, metal bridging and hanger modules to accommodate staggered joists.

[medeek]

So yes, staggered joist present a few issues. For example if the blocking doesn't land in the lapped region of the joist layout you end up with this:

Right at the moment I'm not sure how to address this or actually determine when the blocking lands in the non-lapped sections of the layout. The easy way out would be to do a boolean subtraction using the joists themselves, but then I would need to separate the resulting (multi-body) group into a bunch of groups/solids, this one is a bit of headache.

[medeek]

With staggered joists I am tracking how many rows of joists I need, the joist length and lapped length, so given that information (three variables) I can then run a quick check on each blocking row to see how it pencils out. This little block of code does the trick:

if @Spanno < 2
			stoffset = 'NEG'
		else
			lapcount = 1
			for lapi in @Stjarray
				if (distx > lapi[0]) && (distx < lapi[1])
					stoffset = 'LAP'
					break
				elsif distx < lapi[0]
					if lapcount.odd?
						stoffset = 'NEG'
					else
						stoffset = 'POS'
					end
					break
				elsif (distx > lapi[1]) && (lapcount == (@Spanno - 1))
					if lapcount.odd?
						stoffset = 'POS'
					else
						stoffset = 'NEG'
					end
					break
				end

				lapcount = lapcount + 1
			end
				
		end

As one can see there are really only three possibilities for the blocking: Lapped, Positive or Negative.

The end result is this:

Problem solved. Now I just need to apply this same logic to the metal bracing and implement it. Insulation is somewhat different so I still don’t have a good solution for that one just yet.

[medeek]

After another three hours of some productive thought and hacking away at some rather large blocks of code (and a few choice words) I managed to pull together a fairly efficient and robust algorithm for the cavity insulation between those irregular joists.

Ladies and Gentlemen, I give you “Batt Insulation with Staggered Joists”:

I’m exhausted, tomorrow I might take a small break.

what if i want them staggered the other way? LOL J.K. nicely done!

[medeek]

First look at skewed hangers with staggered joists:

A little bit more complicated than regular joists due to the offsets but overall its pretty much the same routine. Pretty excited that I actually can get this to work, at first I wasn't really sure if it was even feasible.

Version 0.9.9 - 10.01.2024

• Further updated the insulation, blocking, metal bridging and hanger modules to accommodate staggered joists.
• Added skewed hanger options into the Floor tab of the Global Settings.
• Added skewed hangers to the Draw and Edit menus.

Version 0.9.9b - 10.01.2024

• Updated the Floor tab of the Global Settings with additional parameters for joist construction.
• Fixed a minor bug with the hanger module for double ply staggered studs.
• Fixed a bug in the Draw and Edit menus so that all hangers in the library are properly displayed.
• Added the following skewed (45 degree) Simpson hangers into the built-in library (skew_hangers): SUL410, SUL414, SUL214_2, SUL210_2, SUL26_2, SUR410, SUR414, SUR214_2, SUR210_2, SUR26_2

Version 0.9.9c - 10.03.2024

• Enabled diagonal deck boards with the addition of a Board rotation parameter.
• Enabled 2-Ply rim joists with our without an air gap.

[medeek]

Version 0.9.9d - 10.03.2024

• Fixed critical bugs with saving of floor presets.
• Improved robustness of floor attribute library and data lookup methods.

Some incremental improvements but necessary.

IMPORTANT
Note that the last few updates prior to this update introduced a number of new features that effectively disabled the saving of floor presets. Please download this latest update to restore the ability to save floor presets.

Double rim joists with air gap, lapped and extended:

A quick test of the non-orthogonal floor types shows that the algorithm holds up as it should:

[medeek]

Version 0.9.9e - 10.04.2024

• Updated 2-Ply rim joists with air gap to extend joists that are in a lapped configuration.
