Choice of fastener!? pillar vs ridge beam

[draparn]

Hello all DIY enthusiasts and professionals!

I am in the process of adding a gable roof to my existing flat leaking garage roof. I have hired a designer who has made the drawings and sized the construction. He has gone on holiday for four weeks and I am considering the fastenings between the pillars, ridge beam, and load-bearing beam.

I have an idea to put some material between both sides of the ridge beam and the load-bearing beam to get the same dimension as the pillars and then pull everything together with nail plates, but the anchor nails I find measure 40 mm, so at the load-bearing beam, only 17 mm will be fixed, and in the ridge beam, 28 mm. An alternative to this would be to notch the pillar and run a through bolt, but there won’t be much material to attach to. Only 34 mm in the case of the ridge beam?

Attached is a picture. The picture shows the pillar at the bottom and the principle of both the ridge beam and load-bearing beam as seen "from behind."
Grateful for answers!

Use angle brackets.

Use angle brackets.

Maybe I don't understand what you mean, but isn't that also too little to attach to? On the post, there will be 17mm to attach on each side of the ridge beam? Or am I way off?

Do as you planned but drill the holes in the plates so you can fit 6x80 mm screws with a round head through them.

Perhaps you can replace the spikplåten in your proposal with plywood. And use something other than ankarskruv

Good suggestions both!
Thank you for the help!

Maybe I don't understand what you mean, but won't that still be too little to attach to? On the post, it will be 17mm to attach on each side of the ridge beam?
Or am I off track?

Basically like this:

Ah, I understand, great
Now I have three proposals to consider!
