Post base for horizontal forces

[Discharged]

I'm planning to set up a noise barrier and am considering which anchoring I should use down towards my piers. There are a couple of different types of post bases, and I'm wondering which is best for absorbing the force, especially from wind. Will a regular U-shaped post base for casting work, or is there a risk that it will become a weak point and start to sway in the wind?

The frame will be built from either 95x95mm, 125x125mm, or two 45x120mm, so the post base should be 90, 95, or 125mm.

Does anyone have experience with this? Could an alternative be to partially cast in even the post base attachment itself? Meaning concrete so it is completely embedded?

No regular pole shoes that look like a U, they cause wobbling, they are too short. Below are different ones for embedding and they are long and hold well. There should be an iron on each side of the post. And it's possible to use fully threaded rods with nuts on both sides. The wood in between dries and settles, it's good to be able to retighten. Depending on the wind direction, they are cast with the flat side against the wind. To get the correct distance between the irons, take a piece of post, tighten it with threaded rod and place the ends of the irons in the concrete, preferably with a small wooden block between the post piece and the concrete. For alignment lengthwise, use a string so you know the posts won't be crooked in their mounts.

Perhaps I should have clarified that the casting already exists, so I could, for example, use

and attach with anchor mass. I can also cast an additional 5 - 15 cm on top of the existing casting.

Ah, then it becomes a bit more difficult. You can try to attach plank iron on both sides, but it might be a bit of a hassle to get it right. Drill large holes so that you have some wiggle room; otherwise, follow jonaserik's instructions for fastening.

I might have clarified that the casting already exists, so I could then use, for example

and attach with anchor compound. I can also cast 5 - 15cm on top of the existing casting.

It might work, but a bar on each side is probably preferable; with just one bar, it can twist/bend due to the wind. The entire package/cover is like a sailboat, and the force is great to drive one forward, everything is calculated in m2 for wind uptake.
