Shed floor sheeting question

Post by tmccar » Wed Aug 15, 2018 6:32 am

When sheeting a shed floor with plywood, the normal spacing for the joists is 16". So what happens at the edge when starting off - is the edge of the plywood lined up with the centre of the joist (as it will be at the other side)?
Or is the outside edge of the plywood made flush with the outside of the frame? For this to work, wouldn't the first spacing need to be smaller by 3/4" ?

So when measuring for the layout of the framing hook your tape on the outside of the outside end of the rim joists.So for example with both rim joist laying in front of you hook your tape on the right end and stretch your tape out to the left along the rim joists ,now working from right to left mark a line at 15.25,31.25,47.25,63.25 and so on. At each of those lines mark an X on the left side. The mark is the edge of the floor joists and the sit on the X side of the line. All your joists are now on 16" centres . If you prefer you can mark them by hooking your tape on the left end of the rims as well.

This.

Do as Shannon described, or, put a screw into the center of your rim joist and hook your tape on that so that you can use the 16" markings on the tape. Be sure to use the X method so you know which side of the mark to put the joist, it's easy to forget half way through and install on the wrong side.
