Bridging or not?


of course if you are required to have a framing inspection and the problem is discovered .... could lead to delays and extra work

GBrackins.... Looks like I'll be changing those two 2-1/2' i-joists to doubled 2xs. Just thought that a 2-1/2' length under a closet floor would be ok. Thanks for your input and concerns. Learn something new every day. David.

The 3/4" t&g OSB is not down yet, so removing the offending i-joists and replacing them with doubled 2x12s will not be a problem. One of tomorrow's projects. David.

just trying to keep you safe and sound, and without a hitch if you have to have an inspection. I was a fire inspector at one time so I know how they can be.

we all learn new things everyday myself included. Hope your project comes out exactly as you envision it.

GBrackins.... Gary, No inspections here in my area, but I do want to keep the project as safe and proper as is possible. That's part of why I ask the questions.Apparently the last one to work on this house (orig. build 1861) just patched at everything he came in contact with, and I'm left to try to correct the problems. Just a part of buying someone else's project I guess. I do appreciate everyone's comments and suggestions. Thanks, David.

I hear you about old homes. The oldest I've worked on was built in 1719. I'm never amazed and what people can do.

Enjoy the process!

3/4" T&G?

How long do you plan to keep the house? I did my upstairs addition with 1 1/8" T&G......NO REGRETS......I thought the architect was crazy...but now I understand why......the original part of my house is 3/4"....and you can tell a big difference.

Just saying...seeing how you have not put down your floor yet....that 1 1/8" T&G feels almost like walking on a slab....

Bridging or not?


ddawg16.... I'm going to complete the upstairs floor w/ 3/4" t&g, as the part the previous owner had completed was w/ that material. Don't need a "tripping" place in the floor. There is already a space (floor area) of about 10 x 24 completed out of a total of 24 x 28 area. As I understand it from relatives of the previous owner, most of the lower floor areas were re-done about 1960 w/ 3/4" particle board and t&g. Still are rock solid, (as compared w/ other parts of this house). The bathroom and one bedroom were not redone, and the original floor joists and flooring are failing, mostly due to being about 2"-3" above the soil (no crawl space here!). Absolutely suspect a moisture problem (wonder why?). The upstairs area (24 x 28) has no interior walls as of yet, so I will have to make a floor plan after the area is dried in. Sort of backwards, but got to work w/ what is already in place. Yet another project. Thanks, David.

Update:
The "offending" i-joists have now been replaced w/ doubled 2x12s, resting also on doubled 2x12s.

Tomorrow I will be attaching the rimboards, and begin to put down the 3/4" t&g OSB for the remaining floor area. Weather looks to be cloudy, possible showers for the next three or four days. Time for the tarps!!

David.

Your not supposed to mix i-joists with dimensional lumber.

Joe Carola.... The new doubled 2x12s are resting on doubled 2x12s, not on i-joists, therefore no mixing of i-joists w/ dimensional lumber, if that was what your reference was to. If not, sorry for the assumption. The i-joists are in a different area from the 2x12s. The rim board was ordered from the same manufacturer (GAF) as the i-joists, and they say that it is compatible, and made for i-joist structure. A question though, about the fastening of the rim board to the i-joist. Mfg. instructions say use two #8 nails for each i-joist connection, one on the upper rail, and one on the lower. Doesn't seem like much to hold that rim board. I believe that the flooring (decking) also attaches to the upper edge (correct?), so maybe that's where the extra hold will come into play. Thanks, David

It's the same floor right? Am I missing something? Maybe a different area. I-joists are 12" .....2x12's are at most11-1/2" in height. You already have a 1/2" difference in height and dimensional lumber shrinks.
