At Home In The Woods

The joists are looking good. I'm also comfused by the 19.2" spacing. Although, I just did the math and it does work out for 8ft sheets. Must not be a 4ft offset between rows.

The 8'x4' subflooring sheets will be installed perpendicular to the floor trusses. Thus, it takes 5 19.2" spans (6 trusses) to span 8 feet.

Bracing
Glue will go under the flooring and also in the tongue and grooves. The truss designer said that the trusses will be in good shape using these steps.

I never heard of gluing the T&G's. Guess it can't hurt. Don't wear your good shoes..

I have to admit the 19.2" made me look for my calculator...

Eddie: I haven't done any calculations on this, but do you think these trusses being 3.5" wide instead of only 1.5" for dimensional lumber provides enough resistance to them tipping onto their sides to eliminate the need for the diagonal braces?

There's a 1" thick OSB piece that usually goes across the ends of the trusses in place of the 2x in conventional framing. Not just sheathing. That's on the ply-web type that I've used anyway.

Obed,

Thanks for the update. Nice to hear the engineers reasoning and how they want it done. I would have braced it. Still might if it was mine, but that's just me.

We built 3 years ago and looks like we have similar taste.

I have most of the build documented here if you're really bored.

WBWI, your place looks awesome. I love the back deck and the windows looking out the back. I bet you enjoy looking out those windows.

The Advantech manufacturer's instructions specified gluing the tongue and grooves.

The trusses on the end of the house beside the main floor garage are top chord bearing. The concrete walls at this point are 12' high in order to get the garage slab on grade with only a 7" step into the kitchen. The top chord bearing trusses hang on the walls by the top chord. The rest of the concrete and framed walls are 10' high and have bottom chord bearing trusses sitting on top of the walls.

With your 19 inch centers, what will you use for the ceilings? 1/2 inch or 5/8 sheetrock? or are you using sheetrock?

I like the trusses. I've never worked with that style of truss, so I'm finding them to be very interesting. Did you compare them to engineered I beams? Just curious what the difference was that made you decide on this type of truss.

Thanks,
Eddie

Eddie, when we finish the basement we'll put in a drop ceiling. I like having access to the plumbing, etc. so prefer to avoid sheetrock in the basement ceiling if possible.

These trusses make it easy to run plumbing, ductwork, electrical, etc. through the trusses. While I'm not a builder, it seems to me that running stuff through I-joists would be harder because you have to cut holes in the I-joists to run things through them. We specified 24" trusses in the house plans to give ample room for running ductwork, etc. Do the I-joists come in 24" heights? The ones I've seen aren't that tall.

I had to check to make sure, but it looks like Weyerhaeuser has them up to 20 inches deep. I've never used, or even seen them that tall in person.

I have seen them with the cutouts already in them, but never bought them myself. Cutting the holes for ductrwork is one of those things that your AC guy gets to do. They do it all the time, and send in the teenagers to do those jobs. LOL Same with the plumbers and getting their lines through them.

Did you go with this style truss to save on work for your subs? or was their a price advantage?

Thanks,
Eddie
