How to Attach Two Beams at 45 Degree Angle on top of 4x4 Post?


I'm building a deck and I want to attach two beams that meet at a 45 degree angle to the top of a 4x4 post. Is there hardware that can accomplish this? Thanks,

Kevin

Why don't you cut the top of the posts and the beams at 22.5 degrees and then they'll meet properly? There's probably some hardware that can accomplish something too.

After that, you can bolt them together.

Beams SITTING ON a post is a weak connection in most cases. What size are the beams? If they are 2x dimension lumber, you can use a circular saw and a hand saw to cut out 1-1/2" of the 4x4 on two faces, which will give the beams actual bearing, plus a little lateral support to the side of the post. The post can be extended up to just the top of the joists, or can be extended up three feet to be integrated into the deck's guard rail.

I would caution you in making a 45 degree cut to miter the ends of the beams together. Depending on the beam's width and how they land on the 4x4, there is a chance that cutting them that way will not provide adequate bearing surface.

I plan on using two 2x8's for the beam.

I'm having trouble visualizing what everyone is saying... Anyone have a picture???

I had a similar problem but was using 6x12 beams over 6x6 posts. I went down to my local lumberyard and had the salesman get a quote from Simpson for a special order connector, two saddles welded together at a 135 degree angle, comparable to their CCQ66, hot dip galvanized. They wanted $1,650 for fabricating three of them! Another manufacturer was willing to do them for $1,050. If you donít need hot dip galvanized Iím guessing they would be no more than half the cost, and cheaper still if you are using 4x material. The connectors look and feel strong. I figured I needed them since the deck was 12í high and I am on the California coast in earthquake country.

I have a friend living in California and he said nothing there comes cheap...But it sounds like you did the right thing in getting them well made...

Simpson ECCQ post cap - take a grinder and cut away half of one of the upright wings.
Position beams in cap and screw together with FastenMaster LedgerLock screws as well as running the Simpson SDS screws through all remaining holes in metal hardware.
I'd strongly suggest upgrading to a 6x6 post for increased bearing area.

That's a 90 degree angle though. I'm looking at a 45 degree angle??

Leroy; Yes you are. Call your local lumberyard and ask if Simpson makes a 45 bracket. If they dont know call Simpson, might be in a box in a back corner since it is not that common.

Oops. Misread your OP...

Try these - Simpson AC4 (AC6 if you have 6x6 posts)


The top wings can be bent into shape. Put one on each side of your post...
