Poles for building

[chaosracing]

I am in the planning stages for a pole building. I am looking at trying to build it myself. I have built many other buildings in the past, both stick and pole. We built a pole barn at my dads place about 30 years ago. Part of it is below grade (its a barn for horses) and all below grade construction is pressure treated lumber. As of now, there are no issues whatsoever with rot, but then that was good treated lumber and we treated all cuts. All poles were set in ground with concrete around them.

I am looking at perma columns as I do not trust the newer wood to be in ground. However, I am also considering drilling holes, filling hole with concrete and putting a post anchor in the wet concrete, then attaching laminated poles to the anchor. I will also add rebar into the hole to reinforce the concrete. Since that basically is what a perma column is, is there any reason why this approach wont work?

As always, looking back I wish I wouldve just dug holes and did what youre describing. Fill the holes with concrete and anchor the laminated poles to the concrete. Its more expensive this way but I personally believe its optimal.

You have to define "post anchor" as you use it in the O.P. The post must be able to stand like a flagpole, on its own, and in addition, support the windload on many square feet of wall and not blow over in either direction (as viewed from the 4 flat vertical faces).

The steel you put into the concrete has to go deep enough under the surface and high enough to be bolted so it can maintain this basic feature of the structure. if its raw steel it should be galvanized or epoxy coated to resist corrosion.

Imo the perma columns solve all of these issues, buy it, set it, and forget it, no engineering or special prep involved.

That's basically what I did. I made my own base anchors and tied small pier cages.

Thats where I was getting the idea from. I would love to do it exactly, but not sure if I can afford a slab at present time. I am exploring all options.

Just a FYI, I am planning on a 26' x 38'x16' with scissor trusses. Would love to go bigger, but if I stay under 1000 sf ft, I only need zoning permit. Plus budget is an issue as well.

My anchors are 1/4" steel, 5" x 18". For embedment, there are 4 holes in the bottom that have #4 rebar with candy cane hooks on top and straight hooks on the bottom.
The cages are #5 rebar hooks with 6x6 wire.
I poured the piers monolithic with the slab, but considered using sonotube and pouring them to the top. I don't see why that wouldn't work, but I also wanted little rebar mats to tie them into the slab.

Just looking at options. I was planning on either building something like Shootinok did in the post above, or using Simpson strong tie CBPC column anchors, which I believe is what Perma column uses as well.

However you decide to set them, I would consider these engineered poles. I used them on my barn.

Get the perma columns! Like other told me when I was in the stages of design on our barndominium, "buy once cry once". We are very happy with our choice to have them installed! Look for my build thread I took some pictures of the columns and there install.

Morton makes something similar to Perma columns and I believe has an additional internal spline added. Not sure if you can buy them separately from Morton.
