Will my metal poles contained by a concrete slab bend near side twirl? On a regular industrial concrete slab (maybe 6in deep) I am thinking...
On a regular industrial concrete slab (maybe 6in deep) I am thinking of core drilling holes (about 1 1/2 in surrounded by diameter) to insert metal poles of slightly smaller diameter that will stand 6ft tall above the slab surface.
These poles will support a standard panel wall.
Does anybody have any model how much lateral strength it would take to bring down these poles?
I am trying to think if they would bend or if the slab would crack under extreme bend pressures.
This is a serious question, so no joke please.
Answers: try to stay inside the slab about a foot or so...if your lucky you'll procure next to some reinforcement(like rebar). When you put the poles contained by, plumb them up good and re-fill the cleft left contained by the concrete with some non-shrink grout. I speak this because concrete mixes(in bags) are not quite as strong as ready-mix concrete(the stuff that your driveway is made of) and concrete shrinks as it cures. Non shrink grout doesn't-hence the entitle. You can buy this by the small container(like 5 lbs) or in a bigger bag(40 lb) at most hardware stores. The other suggestion I own is to fill the poles themselves next to concrete-to add rigidity. This is a adjectives practice for parking bolsters that are used to protect buildings and other objects. The if you do that, you can get away beside using a thinner walled pipe. The only other piece I'd do is auger the hole deeper into the soil, so you can get the pipe itself within the ground an additional 8" to a foot- that will make available you added ballast. Hope this gives you a few polite ideas!
they should be fine. Use a gummy walled pipe though
