Simpson Beam Seat 1

[JStructsteel]

So it seems Simpson has a connector for everything, except a double 2x beam to a concrete pier. They have them for LVL (CCQM series), but not dimensional lumber.

Whats a good detail for a double 2x beam (deck beam) to a concrete column. Column 12"x12". I am thinking the META strap, but if not an intuitive item like a beam seat (where if they get it wrong, they are screwed) vs a strap they just jam in somewhere.

I thought maybe a nailer plate expansion anchored in and then some clips. Again, just seems alot of work for my end game.

I’ve seen contractors use post bases for this and pack out the extra space with plywood shims.

I've spec'ed post bases as Bones said. Sometimes dbl. A24's. They are not rated but they are 12ga so pretty stout.

Im not thrilled about having shims of plywood on a deck. To me it would look like we didnt know what we were doing.

I did find the ABA24-2Z base, its adjustable so it would fit nicely.

Are you sure they make an ABA24 base? I think the ABA44 is smallest and it is 3 1/2" wide so it needs shims. The adjustable part is the hole in the bottom for placement.

Oh, actually they do. Good to know. Looks like my catalog is old!

 

[JStructsteel]

Yes, looks relatively new

I didn't know about the ABA24 either. Good to know.

But keep in mind it's only 3.125" tall. I wouldn't count on it to provide meaningful rotational restraint for the beam.

Thanks phamENG, the beams will be restrained w/ joist framing into the side.
