pouring concrete in pole building

chucko · Mar 16, 2004

Dude if you put the metal up to protect the truss the open barn will become a big wing like on a plane. Very little wind will case a lot more uplift than you might think. Wedge shaped or not you must strap those post! . run a strap down the side of the wedge and up the side of the post (on each side of the post).....
If you buy insuranse on it and it blows down and they find that it was built below code they will not pay you one dime.

You're right if the sides are left open for very long. Better get those closed up pretty soon to prevent the roof becoming a wing. Another reason to postpone a concrete floor. Better to have walls to stop the wind in the first place than to try to use a slab as an anchor.

and if the sides are up and the wind blows, the bottom of the unanchored post could blow out and the whole thing come down. Just like putt you truck against the post and pushing....last time I am saying it ....you got to anchor those post!

</font><font color="blue" class="small">( Peter you summed it up quite nicely.

I also put up a 24 X 36 pole barn 2 years ago. The concrete work is very nice but that only because I hired it out. I'm not a concrete man and I know my limitations. That's one challenge that I'm glad I didn't take on myself. )</font>

I also have a pole barn. 28 x 40 (3 bay + workshop) with a 6" reinforced fiber slab with NO expansion joints.It was built in 6-2002 and the floor poured in 6-2003.This is the 1st. winter for the floor and so far found NO cracks.I had ALL work done by the pros,both were 3 men crew.(built and poured).I waited a year for settling before pouring and believe that makes a huge difference in the overall outcome of the project as a whole.I'll try to get some photos posted.

Another idea to throw out to others for consideration. Would there be any benefit to placing the metal roofing on except leaving out a few sofit-to-ridge strips of roofing on both sides of the ridge in one or two spots? Essentially creating big wide gaps in the roof until you can get the anchoring done. That may give you some protection to the trusses but decrease the "wing risk."

I think the anchor bolt idea is still the winner--even though some posts are only 6"deep they will be tied to bedrock--can't get better than that.

Let others comment if my idea has any merit. It is just and idea...never tried it before. Just trying to help if able...good luck

I think it's a good idea to leave as many openings in the roof while still sheltering the trusts from weather until you get the sides on and the posts anchored. The more openings the less lift. But I agree with chucko that until you anchor that side into the bedrock you'll be taking risks.

Hi
You might try renting a core drilling machine and drill holes next the each post and set pipe to anchor the post too. drill the holes at a 45 degree angle if possible check this link for the type drill I am referring to.

hey MOPO

I'm with the others, you HAVE to anchor the posts,
get some ANGLE IRON either made or buy small pieces. 1/4" thick, by 3 or 4 and 6" long. drill and anhcor them to the rocks using 6" or longer RED HEAD ANCHORS available from grainger they are not that expensive and can be had in lenghts up to 12" long by 3/4" dia. two per post is what I'd use and use a HAMMER DRILL which I would rent with the bits.

I'm with Chuck. I don't see anyway you can get that building safe. Even when anchoring to concrete you need footing that are 3-4' in the ground. It won't take any kind of a wind to pick that thing up and destroy it. Even if you pour a slab you are asking alot for a 4-6" slab to hold down the building. I don't think it will do it all.

You are a good go-getem type person. I wish I had your ambition & spunk.

No go do exactly what Spiker said. Or what all of us are saying - I just happen to like Spikers specific directions. You need those posts anchored _down_, not sideways. I thought this issue was solved several weeks ago. Without a proper footing/ anchor, your building is fairly worthless. If you need to cut costs, skip the floor for now. Skip the siding. But you need it held _down_. There is no shortcut for this. Most especially anything less than 2' in the ground.

Just do it. /forums/images/graemlins/smile.gif Anchor _down_.
