Fastening glulam beam in post shoe

[Pappa1986]

Hi

I'm in the process of digging down pre-cast plinths. The post holder is 90 wide. The beams are 115x115. There are probably 2 options, cut one of the iron pieces sticking up and fasten from one side OR "hollow out" the beam so that you instead insert the iron piece into the beam. Or does anyone else have a better idea?

Thanks in advance
Regards

Place a 90 beam in the post base and then attach the 115 beam to it?

Attach a 90 beam to the post shoe and then attach the 115 beam to it?

Yes, that would work.
Then I can lay some 90 beams horizontally over all 6 piers and then place these 115 on top.
Attach the 115 beam with angle brackets to the 90 beam or what is recommended?

Isn't it a 115x115 laminated timber post you want to attach? In that case, the best solution is to cut off one of the irons using an angle grinder with a cutting disc. The post must have proper support underneath with only sill paper between the foundation block and the post. Wood can withstand much greater pressure along the grain than across the fibers. A 115x115 laminated timber post that is 2.5 m high can handle a load of around 13 tons; it's important that the rest can handle it too.

Isn't it a 115x115 glulam post you want to attach? If so, the best solution is to cut off one of the irons using an angle grinder with a cut-off wheel. The post must have proper support underneath with only a sole plate between the foundation and the post. Wood can withstand much greater pressure in the direction of the grain than across the fibers. A 115x115 glulam post that is 2.5 m high can handle a load around 13 tons, the rest needs to do so as well.

Spoke with the local building supply store today and I notched the beam and embedded it into the wood instead. No major difference (according to their calculation anyway)
Thanks

The difference may be marginal, but it is fundamentally wrong when it comes to load-bearing posts.

I'm in somewhat the same situation as you now. What did you do to solve the problem?

Talked to the local hardware store today and I notched the beam and embedded it in the wood instead. No major difference (according to their calculations anyway)

What weight do you think the post shoe on the pre-cast plinth can handle? I would guess it can't handle 12 tons, but that's just a guess.

On the other hand, the post is "on" sill paper and the concrete, so it mostly functions as a stabilizer, I can imagine.

What weight do you think the post bracket on the pre-cast plinth can handle? I would guess it can't handle 12 tons, but that's just a guess.
