Glulam beam how can you fasten to the floor without angle brackets?

[kladde]

It might have worked with an ordinary angle bracket.
Screw the angle bracket to the floor, place the post on the angle bracket, then screw the protruding part of the angle bracket into the side of the post.
Then cover the protruding part of the angle bracket with the skirting board.

Yes, that was suggested by the company that calculated it. But then they wanted large angle brackets with reinforcement. This would make parts stick out too much, and the skirting board wouldn't be able to cover it. Didn't feel like arguing about it, so now it'll have to be with rebar.
