Lamella Structure joints

I am attempting to fabricate a lamella structure which I have succeeded in creating in grasshopper. However, I am unable to figure out how to create joinery details at every point that there is an intersection. If anyone has any clue as to how to solve this any advice would be greatly appreciated.

Best,

Matthew

How do you intend to manufacture this?

If you construct it as a "waffle" construction (halfway slots in each section piece that slot together) then because the sections are not at 90degrees the slots would need to be cut at an angle to the surface which is difficult to do.

You could allow for the angle and make the slots wider and normal to the surface, so they could be laser cut or cnc machined, based on the angle and thickness of the sections. This won't look so good though.

I think it's important to understand how you will make this before trying to generate the detail otherwise you might spend time drawing something that cannot be made. Do you have any info on how similar things have been made?

As Martyn said.

BTW: in case of a "waffle" this is the most primitive join imaginable (don't attempt it for serious spans/loads).

As usual (attachment not worked). BTW: this is 3DPDF

This is a good example... it shows sections crossing at 90 degrees. When they cross at different angles then I think you need a different solution or a very good carpenter!

Term "primitive" used ... er ... for good reason. Of course there's 666 other possible solutions (from extra cheap and ugly to mega expensive and ugly).

I'll post later my favorite "jack-for-all-trades" (the N666, what else?).

Sounds good, especially if it utilises a nail gun and a big hammer

JFAT (N666) requires only a sledgehammer (the bigger the better). It's not that cheap but if you order more than 666 assemblies I can offer a rather generous 0.0123% discount (sledgehammer is included to the package).

Use ModelTree in Reader (3DPDF around) and the section thingy.

As usual ... any attachment is impossible. I'll try later

yeah, that's a nice solution.

If the structure were to have panes of glass, for example, how would they be fitted?

I would strongly suggest "hinged" extrusions mounted on top of the beams kinda like the custom systems that my best friend Stefanos uses in Dubai (and in many other places):

BTW: WOT (the Big Brother in Modzila) reports that the above site has a poor reputation. But since Stefanos he's just a genius ... I do hope that the competition (if any, that is) ... blah, blah.

If this sounds expensive (it is) try ATRIUM type of systems like:
