Bunch of added work and time GB but yeah, I think I'll have to do both of those things before I finish putting down any more flooring. Gotta say it's a royal pain in the knees to be climbing over those joists repeatedly...
You may be able to get by with just adding the joist to ground supports on every other joist and not every one.
Depends on the max load you ever intend for the floor to 'see'.
Heaviest load would probably be me at ~300#/sqft. Then again, since the goats weight is all on a small hoof, that may equate to more than that. Either way, no heavy machinery or bulk storage. I think I'll do the joist to ground on each and put a paver or brick under to keep it from sinking into the ground over time. I have extra of both pavers and bricks lying around. Think I'll put one each at the mid point of the 12' sill spans as well.
Yes, I meant to show the other 'legs' along the ends of the drawing's 'side view' but forgot.
Keep in mind, that the frame is already holding up significant weight...that of itself. With nothing to support the middle part, it will sag under it's own weight over time, the floor will become dish shaped and screws will begin to pull out from the ends of the joists and it won't take long to show up.
Place a 16' 2x6/8/or 10 on it's edge, with a brick @ each end, and within just a few weeks, the center will bow down from only it's own weight. Gravity, it's everywhere and it never sleeps..
looking like the girls are going to be snug as a bug in a rug this winter. i'm sorry you are having to deal with so much discomfort with your hands and knees. hope it gets better. and I hate to admit it but I did get a little chortle out of the flying pig comment. hate that you lost the board tho.
All of my aches and pains decided to migrate south yesterday afternoon and settle in my right ankle and foot. It got so bad I wanted to crawl vice walk and put any weight at all on it. I don't have a crutch and considered breaking out one of my shotguns to act the part. I did get animal chores done but it was so bad by 8:30 that I took an opiate pain killer combined with an Excedrin and a Ibuprofen and a new arthritis pain killer med they gave me (that I can't tell if it's working or not) and went to bed. Didn't finally get to sleep till after 1am. By this morning, most of the pain and swelling had subsided and I put on compression socks and compression knee sleeves. Been damp and misty here all day so decided no work today.
On the joist supports, I've decided to marry both examples GB showed. I'll nail in a "T" between joists with the center support down to a paver so I can support 2 joists at once.
I called and made an Enterprise rental car reservation for pickup Friday and return Monday. My truck is getting old and tired and it's not that I don't trust it for the trip this weekend, but with the better gas mileage from the rental, it won't cost me more and probably will work out cheaper to make the trip. They said I could park my truck there over the weekend. I reserved a Hyundai Elantra "class" vehicle but they can't guarantee make or model, so I have no idea what it will be. Guess it will have to be a surprise when I go to pick it up.
@CntryBoy777 Based on maps and projections, I should be at out meeting place between noon and noon:30 on Saturday. I'll let you know what I'll be driving so you'll recognize me (maybe)... I expect we will arrive at @Mike CHS's place some time around 3pm or a little later.
Rental cars are the way to go. When Teresa flew to Charleston last week she actually spent less on air fare and a rental car than I usually spend driving there and back.
