Working with I-Beams
« on: June 06, 2005, 07:55:52 PM »
Can anyone help me out with some general information about how you work with I-Beams?

I'm curious about how you'd go about doing the blocking between them, as well as how you'd attach the rim joists (if you use them at all?). For instance, assuming you were nailing plywood sheathing down the side of your wall such that it overlapped the subfloor & joists, you wouldn't want to nail into the sides of your I-beams, or the ends of them I'd imagine, so what happens here?

Lastly, if you were using I-Beams for the floor of a second story, can you use normal framing techniques for building the opening for the stairs, where one of the joists has to be cut shorter than the rest, and some kind of double/triple header put in between the two on either side for it to attach to?

I'm not sure if I've described this very well.

Andre, you attach the rim joists by nailing into the ends of the I-joist flanges. You can nail your wall sheathing into the rim joists. And yes, you head off stairwells and other openings using techniques similar to those used for dimensional lumber. The main difference is that you need extra blocking to pack out the webs to the same thickness as the flanges. Probably any detail you'd need is illustrated in TJM's "Pocket Guide", available here (bearing in mind that other manufacturers might have slightly different requirements)...

JLC also has an article on "Framing Floors With I-Joists"...
