Hi guys,

I had been having some discussions in another thread, but I think it ran out of steam! :-) So I hope it’s ok to start over with a couple of questions. So:

1. What is the best (accepted) way to join beams together? My lumber arrives tomorrow, 2×8’s. I have a 20’ ledger that I am assuming is ok to butt join on the wall (brick), and of course a rim beam of the same size.

How do I join them, should the split be in the middle, over a concrete pier, etc.

2. Using the existing concrete piers I will likely have to do some shimming. What material, and how will I secure the shims? This is only a couple of inches above the ground level, so no access from below.

Thanks again!!!!

Hugh

Whoops !

Sorry.

Thought you said Jim Beam, and I had a few ideas.

Never mind ;-)

There may be a building code issue, for your location, that specifies the maximum span of a 2×8. When connecting the joist to the rim joist some locations require joist hangers while others permit butt and nail with 16d. Also, if one of the rim joist is to be connected to an existing wall, and that rim joist must be “hung” from the existing wall there are probably code requirements for the size, number and location of the hanging bolts.

Hi lew,

I will be using joist gangers throughout, and I don’t have an issue with span – the concrete piers are 6 feet apart. The deck will be a cantilever, and hang around a foot beyond the front of the concrete piers.

I was wondering, if I join the beam on the front of the deck, how should that going be done? For example, would I butt join, then have a plate carriage bolted to to the inside face? If so, how many bolts, how long a plate, can the plate be the same 2×8 as the beam, etc. Make sense?

Thanks.

Hugh

Hugh just butt the beams together and split them half and half on the concrete .
You can buy metal plates that you can nail on the face of the beam to mend them together . They are the same plates they use to attach trusses .

You can get them at any lumber store .
