Question

deck joist to post fastening


was wondering if there is any reason to use brackets with screws or nails when affixing 2x8 joists to 6x6 posts rather than just simply nailing them in with a framing nailer and hot-dipped galvanized 3" nails? or really anything else on a deck provided it can be reached with a big nailer?

also, when suspending 2x8 joists and using a U-shaped bracket, any reason to go with 10d 1.5" nails rather than 8d ? so far i've been using 8d and they work fine

For any connections, stick to manufacturer's specs, they are usually spec'd to accommodate building code.

Typically, using nails is fine (and recommended) unless you want to buy the special structural screws from simpson. Do not use normal deck screws.

For joist hangers, also stick to the manufacturer's specs.

Here is simpson's nailing guide. It lists nail replacements, but you need to adjust the load factor. Unless you are an engineer, you will have a tough (i.e. impossible) time convincing any municipal building inspector to accept your load calcs on anything outside the scope of building code or the typical manufacturer's specifications on structural fasteners.

Why would you be nailing joists to a 6x6? Don't you have a ledger against the house and a girder at the end where the joists sit ON TOP of?

For posts are you referring to a post-to-beam connection for a supporting post, or a deck railing post?

the deck is affixed to the house on one side and the shed on the other. it is about 90" wide and there are also 3 posts in the middle of the width that are 6x6 and sit on 3' deep concrete piers, for extra rigidity. both the shed and the house side have 2x8s that are perpendicular to the deck joists and that's what the ends of joists are suspended on.

so i guess there are2x8 ledgers on both the house and the shed. i can easily put a girder underneath the shed side ledger because i haven't sided the shed yet if you think that makes sense. both the ledgers and the joists are 2x8 and the posts are in the middle for added firmness, like i said because i didn't wanna just have joists suspended on the ends (this is probably an overkill but oh well)

Three posts that go right to the joists? so at only three joists? There is no girder?

You say it is 90" wide, but how long is it?

Why not? Why are you building a deck when you have no idea how to build one?

How come you don't have permits? Can you answer this? Why don't you do the right thing and ask your building inspector?

Why do you keep avoiding the question? How come you are not getting permits and inspections for your deck?

Are you above the rules? Do you always do illegal things and come on the internet and ask questions about doing something illegal?
