Casting for gate AGAIN.... SIGH!!!!

[naresjo]

Hello
I have now cast for a small cozy garden gate designed to keep the outlaws (my little guys) on the right side. The gate and posts were pre-painted and ready, started fastening the posts to the respective joist hanger. And what happens, the darn post starts giving in... In other words, it's too weak for the heavy gate...

So now I'm considering removing the existing ones, making new posts that I will put DOWN into the cement about 50 cm, attaching a crossbar to each embedded post, filling the holes with cement AGAIN, and saying a quiet prayer...

What do you think, will it hold??
Or are there BETTER options to do?

Embedded wood will unfortunately rot.

Was it the joist hanger that bent, or was it the wood?

If it was the wood, I would place a support post about a meter from the first one and then create a triangle with the post as the vertical side.

Was it the joist hanger that buckled or was it the wood?

If it was the wood, I would place another post holder say a meter from the first and then make a triangle with the post as the vertical side.

I completely agree that embedded wood is a "no-no". If it was the joist hanger that buckled, then construct your own, stronger joist hangers and cast your own post holder. Make sure not to attach the post with a French wood screw, but rather with a through-bolted stainless steel screw+nut.

Then maybe you should consider whether the gate is properly constructed; it sounds like a very heavy gate? Unnecessarily heavy perhaps?

It doesn't rot that quickly. My entire fence is made this way, and it was surely 20 years ago that all the posts were pressed into the concrete, and none have rotted yet. Say it lasts for 30 years, isn't that enough?

Then it is probably pressure-treated timber, likely class A.

I used a beam shoe of model L. But I'm trying to use existing posts and type flat iron on either side of the post, with through bolts (as you said, I listen sometimes). I'm considering casting a "channel" between the posts where I lay rebar to stabilize it further.

What do you think about that?

Was it the foundation itself that failed? If so, it might help, but if it was the post's mounting in the foundation that failed, then it naturally doesn't help at all.

If it was the plint that folded, the triangle model is also recommended but with a significantly larger rear plint. The goal now is to balance the gate and the rear plint against each other.

The post is a glulam post 90x90, nice fn quality! It is probably the beam shoe and the attachment itself that don't hold.

Now I'm trying with new iron and channel.

If that doesn't work, I saw some nice granite posts for a little less than 2500 SEK each. And if I keep at it for a while longer, I'll soon reach that amount...
