What load-bearing timber?

[Tiggrawastaken]

Hello! I have widened an existing window and installed double doors to the patio. I have installed two 45x170 beams, screwed with Waf screws, glued together, and placed under the 100x100 beam/post that needed to be supported! (the old beams) (the house was built in '42)

Now to the problem: the existing support beam for the upper floor joists is notched about 15-20 into the (100x100) posts and about 20 +/- is hanging freely with only some form of tongue-and-groove beneath it.

HOW do I support this if I can only use 36x145 as suitable timber to secure the wall, since there is no 36 thick timber classified as load-bearing... Help

And yes, I should have made the support beam wider so it would fit directly, but now I've messed up so...

Hello! I have widened an existing window and installed a double door to the patio.
I have installed two 45x170 screwed with Waf screws and glued together, placed under the 100x100 beam/post that needed to be bypassed! (the old beams)
(the house was built in -42)

Now to the problem: the existing load-bearing beam for the floor above is notched about 15-20 in (100x100) in the posts, and about 20 +/- is free-hanging with only some form of beadboard beneath it.

HOW do I bypass this if I can only have 36x145 as suitable timber to assemble the wall? Since there is no 36 thick rated as load-bearing timber... Help

And yes, I should have made the bypass wider so it fit directly, but I messed up, so...

Whether this will hold without settling, I have my doubts...
But you can buy 12mm construction plywood and rip strips of 145mm that you screw and glue up with wood glue, meaning three layers...

Why would you need any specifically graded construction wood?
Follow the excellent advice of 3 layers of K-plyfa or nail up a wide knot-free one-inch board and glue an osb on.

But you can buy construction plywood 12mm and cut strips of 145mm that you screw and glue with wood glue, in three layers..

I thought because it will support the bearing beam above as I have removed 1 stud/post (100x100) that it was notched into

I thought because it will support the main beam above since I've removed 1 rule/post (100x100) that it was notched into

There probably isn't any other classified construction timber in a house from the forties, so you'll probably manage with a board.

There is probably no other classified construction timber in a 1940s house, so you're probably fine with a board.

Haha true true!
