Post Anchors - Need Help

[daBear]

Come spring time I will start a pole barn sort of structure over a 16'x40' concrete slab. I will use treated 6"x6" for post and I almost fainted when I saw post anchors were going for $20 to $50 each these days. I am just talking about galvanized two sided or four sided metal that folds up and is nailed to the bottom of the post. The post sets on a u shaped perch inside that to keep the water out. Man this is high priced. The anchors will cost as much as the post.

Tell me how to anchor a 6x6 post to bare concrete without spending that on anchors.

Why didn't you just set the poles in the ground first then pour the cement later?

Cause the cement has been hardening for about two years.

Drill a 5/8 hole in the concrete and a 5/8 hole in the bottom of the post and use rebar to help anchor the rascal. It will at least keep it from sliding around.........

If you do use rebars, slipping some large galvanized washers over the bars before adding the posts will keep them off the floor and dry.

I don't have a good replacement for the post anchors. However, the suggestion about the rebar is not going to work. The post anchors are required for uplift, to hold the wood structure down in case of high winds or seismic movement. The rebar isn't going to do that.

I suppose you could fool around with some expansion bolts and short pieces of angle iron but that would probably be just as costly as the anchors. If you haven't set anything in the concrete when you poured it then you are going to need some sort of pricey anchor bolt or adhesive anchor anyway.

Happy, you are right on target. I never intended to put a roof over this pad but you know, plans change. Now I am going to have to pay the price for at least $20 apiece anchors. I was just having sticker shock yesterday as the post don't cost much more than that. PHOEY!!!

Get some length of strap iron, bend them in an L shape, fasten them to the pole with lag bolts, hammerdrill and fasten to the concrete ???

Just a thought ....

how about drilling normal pole building holes on the outside of the slab and then build your pole barn. You could always pour a finish 12'' strip around the edge. This would make for a more sturdy building. Thoughts All????

You could use treated 2x6 as a "sill plate" and fasten your posts to it (like traditional frame construction) then bolt the 2x6 to the pad. Gives you a bottom nailer for the sheathing or siding too
