Cross bracing 4 new sub floor - duct in way!
Posted: Sun Jul 17, 2011 10:14 am
Good Morning my friends!
I call you this because so many of you have helped me in your own problems and solutions on this forum. Love it, love it, love it!
I need help and can't find my exact problem on here, but I am probably missing it.
I have a 97 Clayton La Vista (single wide) and needed to replace the vinyl as well as part of the sub floor. We have the sub floor repair area (about 2 1/2 feet wide by about 3 1/2 feed long) mostly pulled up. The length of this cut runs perpendicular to the joists. We pulled up small sections of the sub floor between joists to work on one at a time. We are placing 2x4 cross bracing under the old sub floor, allowing for some of the 2x4 to show to act as support for the new sub floor. This area, if you can imagine, is the center walk area of the bathroom. The bathroom is about 5 x 5 on floorspace. The tub sits at the back of the room and it's length runs parallel with the joists. The toilet and vanity are to the right of this repair and a wall is only inches to the left.
Here is my problem. We have soft spots because pieces of the sub floor met in between joists. On top of this, one corner of the sub floor met in between joists at the floor register. That section of floor became incredibly weak. I **thought** that the air duct (sheet metal box) was below the floor and a collar of some sort came up to meet the floor. I planned on bracing on each side of what I thought would be there. Oh no! This duct - cross over from the main trunk- simply has a hole cut into it and was somehow attached to the underneath of the sub floor. It rests in between joists which I need to cross brace for the new sub floor. The vent was positioned, in all their infinite wisdom, directly in front of the tub and toilet so you MUST walk on it. I don't see not bracing it being an option.
So....how in the heck do you manage cross bracing when the air duct lies in between the joists with the top duct being flush with the top of your joists? Can the duct be removed? We have to keep the register closed anyways because it gets too cold/hot for that small of a space. And, if we can remove it, any suggestions how to maybe cut it, pinch the edges and seal it off from the inside of the house without going underneath and cutting into the underbelly?
Since this involves sub floor repair, I didn't use the HVAC forum. Please correct me if that was wrong. Also, this is my first post. I read details are needed, but was this too much?
Thanks for any advice!
