Well, the time has come. I have been pushing my house up for about a year and a half. Finally dug some footings in the basement and I am ready to move my basment stairs.

New beam runs perpandicular to floor joists, from end to end right in the middle of the span.

House is balloned framed, no real interior load bearing walls.
The only thing that carries any weight in the house is the beam that runs directly underneath one side of the stair way. This beam carrys the one side of staircase and then a partition wall upstairs.

I am going to fab some steel columns for east and west ends.

What I am looking for is a pre fabbed permanet post for under this beam, that still has the ability to be adjusted.

I am sure I can fab one up using some big ACME rod and nuts. I am not sure how I would want this to work though.

Any help, any links, any past experience would be great!!

P.S. I use 4 Screw Jacks to do this, not those stupid adjustable columns.

I guess I missed something.

Anyway, seeing those pics makes me laugh because we've all jacked up beams in old houses the same way by putting a new temporary post right on the slab. Nothing bad happens, but when we make it permanent, we have to dig a big hole, hump buckets in and out and pour concrete. The temp posts hold all that weight just sitting on the slab for days/weeks/months. Yet, when it's "for real" that slab just ain't good enough.

Just like when you drive by someone who is temporarily supporting a massive front entry portico with two wedged-in 2x4s on a steep angle in the dirt. Go figure....

Hey I resemable that Greg. I tried using my big screw jacks directley on the floor but they pushed through the 1 1/2" of concrete. You are right, it would make more sense to dig the foorters first then jack. I have been at this for 18 months. I carried about 20 buckets out too.

I once had a huge porch held up with a few FJ 2x6's kicked way out. I even told the HO I could save her some money and just leave them there!!

At least it makes me feel better that most of us think alike!!

Can't blame them.
After hand digging the last 3+ feet
to make it a basement, they probably
felt like hand mixing concrete for 1½"
was plenty!
After one of those punched through
early in my misbegotten life, I started
to build cribbed up temp pads for
jacking.
Typically a couple 24" 2X12's
side by side with a couple of
2X12's stacked cross wise
to set the jack/post on.

Lately I use some 16" or 18"
LVL scraps...nice pads.

Yeah I had all sorts of boards speard out.

This half of my basement was only a crawl starting out, the other part was full.

Can you imagine when someone decided they wanted some more storage in the basment, grabbed a few shovels and got to it?
