Building 2nd floor of outdoor shed?

Question

The Yahoo community helped greatly to select the size of the materials to build a 2nd florr for my shed. 2 X 6 beams with 3/4 inch plywood is what I will use.

Question: With 2 X 6 beams, I assume I will need 8 " nails to secure the beams to the wood frame. How many nails on each end to lay the beams?

Also, what size nails or screws to secure the flooring to the 2 X 6 beams?

Answer 1

I think you should get someone to help you because if you think that you would use an eight inch nail to nail a 2x6, there is something wrong and it could be dangerous.

You have me lost here but I will try to straighten you out if time permits.
The joist should lay on top of the framing if posible. If you are starting the floor, say half way up the wall, you need to put a band (2x6) around the perimeter of the room to secure the joist to.
You need to find a starting place in one of the corners and use a level of some type, 4 ' carpenters lever, or better is a cheap lazer level. You can buy the cheap ones for 20 or 30 bucks, but you need to get a lone all the way around the room to put the band to.
Use 1/4" or 5/16" lags screws 3 1/2"s long. Set each piece of the band up there as you go and mark the center of each stud and then drill a hole the same size as the lags you are useing.
Set each piece back up there and drill a pilot hole through the holes you have already drilled and then bolt it up.
If you have a cordless drill, measure down from the line you have made 5 1/2" s for a 2x6, 7 1/4"s for a 2x8, etc.
I didn't catch the first question you asked, but if the floor is going to be more than 9' wide, you will need to go to a larger timber than a 2x6 and I am looking at the code book. A 2x8 will go up to 13' 2". A 2x10 will stretch out to 16' 10 ". That is for spruce joist. southern yellow pine will go a little further.
Look, I have got to go, but if you e-mail me at [e-mail], I will get back with you on it before you get started and listen to the wrong person and do something wrong.
I will tell you exactly whats in the code book.
God bless

P.S. I will try to find this question again and give a better answer but construction is my thing and I get lost on this dang comtraption, LOL.

Answer 4

You won't be nailing the 2x6 through the long way. a 16 penny nail will do for securing the 2x6 to the wood frame. The 2x6 will be up and down the same as your frame will be. you should put at least 3 nails per end 1 in the center and 1 on top and bottom about 3/4 inch to 1 inch from the end. screwing down the plywood i would suggest at least a 1 1/4 inch wood screw. That will give you the 3/4 inch plywood plus 1/2 inch into the floor joice.

Answer 5

Just use 16 penny to toenail the beams in place. Two nails each side. I assume you are placing the joists on the top plate of the first floor. If you are dropping the floor down and nailing to the studs, you could end nail with 10 penny nails. But you might want to add some blocking under the joists. For the decking, just use 8 penny every 8" or so. You can use some construction adhesive on the joist, but for a shed, I wouldn't worry about it.

Answer 6

don't just use nails bro, if you want this to hold up, use joist hangers for 2x6's and you nail them with fairly small nails....otherwise wind and walking on the 2nd floor will make sure those nails come loose and then you have big problems......i'm supposing the first floor is stable enough to support a second floor, esp. if you have walls and another ceiling...you might need to strengthen the lower part first, like with plywood sheathing inside or out, not just drywall........you need to have lateral support, not just horizontal. For the decking, you can get coated screws that screw in MUCH easier. 2 1/2" screws would be plenty long enough....better to have more screws than fewer longer ones. {if you're using particle or chip board, don't let it get rained on...it's sucky material anyway, if you can afford it get real plywood}

Answer 7

No! Use 3 1/2" nails and toenail- put them in at an angle from the sides. \|_|/ . Three nails from each side. For the flooring, if you use two inch you will need 3 1/2" nails or screws. I would advise not to use 1" flooring. Not strong enough. 3/4" plywood is OK if you space the floor joists at 16" oc.

Answer 8

It's best to use Liquid nails and 3" screws.....Don't use 8" nails that would be a spike;)
