    Shed floor framing question

    I am building a base for an arrow metal shed.

    Size is 10x12

    Thought I had this all figured out but now sid (self imposed doubt) popped around just after I got home from HD this evening.

    My plan was 3 deck blocks down each 12th side of shed.

    Then using 2x6x12 across top of row of three deck blocks.

    Then simply screwing 2x6x10 across from side to side to act as joists for floor.

    Typing that with cheap Osb tongue and groove for floor.

    1) So do I need to use joist hangers to secure the 2x6x10 to the 2x6x12's end to face? . Option 1 in very rough sketch.


    Or should I be getting a couple more 2x6x12's and resting my 2x6x10's on the existing 2x6x12's as supports for the joists? Opt 2cin very rough sketch

    Funny you should ask.

    I built a 10x12 shed 30 years ago. Now I am just starting a new 10x12 shed.

    My old shed was 2x6 with NO joist hangers. I don't remember how many support blocks I used but I think 6. I did not use any PT at all. I used to park my Suzuki 850 in the shed.

    My new shed will also be 2x6 but WITH joist hangers. I just like the added strength, and they don't really cost all that much. I am also using 9 support blocks. 8 blocks around the perimeter and one on the center, spanning 2 - 10' joints on the middle. I don't believe I did that 30 years ago, and the floor is still strong.

    I don't know how thick the floor is on the old shed - I think 3/4. The new shed is going to be 3/4 plywood, not PT.

    What is correct - I don't know, but my old shed lasted 30 years and the new shed is going to be better built.

    I will post a couple of pics in the next days or a week or so. I plan to have the decking done this coming weekend.

    A 10' span for 2x6 is pretty far so depends on what you plan to store in it, I'd consider 2x8 s. Option 1 should work (your pic is upside down btw). If you're screwing them on, probably can get by without joist hangers, again just depends on what you plan to put in there. they aren't that expensive, so I'd just add them.

    I agree with Darren on bumping the floor joists up to 2x8's. The old rule of thumb used to be if you are nailing through your rim joist into the floor joist then you don't need hangers. I am guessing the old timers were counting on the shear strength of the nail. I would not trust the 12 footers to carry the load alone and would doubling them up. And would get 3/4 adventack for the floor. As the tile guy says 'There is never enough time to do it right, but always enough time to do it twice.

    oh boy, here i was thinking i was overkilling it. lol

    BTW thanks for feedback guys where would i be without your advice.

    will return the 2×6 and go for 2×8 and get hangers.
    This is only a 5.5ft high shed and its only temp while we here.
    Dont think i will keep it when we move. more likely end up in trash.
    Going to do what Allen did long time ago and that is get the wood out of the shop. And some other space eaters.
    Maybe ,maybe lawnmower in winter.

    If you have half as much wood scrap as I do you'll be glad you went with the 8"

    10 x 12 shed for scrap wood. How ever will you decide which half goes into the shed and what stays outside?

    I had to use more wall space in the shop once I put the drum sander and snow blower back in the shed.
    I only store sheet goods in the shed now. Its not so much the foot print of space they use, its the constant having to move them every time they are in the way of something I need to get too. small shops, a lot of moving stuff constantly.

    This was not going to be a 10x 12 and after digesting the consequences of my actions and your feedback I wish I had stuck to my original plan. Dang. It's my fault and I will sort it out.
    cheers
