Footing Tubes

[kentuckycabin2]

Does anybody have experience using the footing tubes found at www.foottube.com?

Do you use a simpson connector with these?  How do you fill with rebar?



Many Thanks In Advance!

These appear to be a variation on Sonotubes with Bigfoot bases attached----a setup in very common use here in Alaska with excellent results. Rebar cages are fabricated and placed inside prior to pouring concrete. Standard Simpson connectors are used with them.

These are tapered so the ground doesn't freeze to the piers and lift them.  It say straight piers can lift and snap. 
Anyone here seen or heard of a pier snap from heave?
I suppose in extreme seasonal temps and the right soil, a weak pier with no steel in it may.

Thank you very much. I was trying to figure a way to get the piers with footings for the barndominium -- these look excellent

I should be able to dig the holes with the tractor and post hole auger too

loading is spec'ed at 2000 per pier under worst case soil (soft clay) -- way more than I will need

the directions say you can put rebar into the tube before you pour or even into wet cement (before seems easier to me )

And I just checked dealers --there is one only 30 miles from the farm !!!

relief !!

thank you

How do you attach the simpson bracket to the tube?

[John Raabe]

You can wire the bracket to a couple of sticks sitting on top of the tube. The sticks hold it in position while the concrete sets up.

You can also attach the brackets to the beam first, position the beam properly with temporary supports and then fill the tubes.

These aren't sono tubes but you could do a similar thing  above the forms / tubes your setting.

Hi Peg, Just curious. Those beautifully mitered forms. Was it just easier to make them that way, or were they intended to be left there?
You do such beautiful work it's not always clear what's going on.
The old jar head here.

  The forms where left in place, architects house he may even have made the boxes / forms for us I don't remember. But they did stay. You can see some other PT 2x4's that defined the walk way and attempted to hold the gravel in place.
