Good Morning Friends,

 Another Saturday has come around and today's quiz will follow;

 

In heavy construction of large concrete buildings, built with forms steel and concrete. Certain different methods are used. What is meant by the use of a stiff back?

Isn't that the method used for making detachable stiffeners. Usually employing a commercial device to temporarily fix a two by to the form panel?

I'll bet Morris has seen plenty in bridge construction.

So this has nothing to do with the British and a stiff upper lip?

 

got me. 

 

Tea?

If stiff back is the same a strong back it is the bracing holding the walers straight.  We had the vertical studs outside the plyform then 4x4s horizontal to hold the wall straight, then vertical  strongbacks to keep the walers in line.   This was for stick built forms, today they have new systems for forming.  Roly   (Glad I was a lot younger back then.)

Or is a stiff back what I get just thinking about those days.   Roly

Yeppir, stiff back is what I have from trying to do concrete work.

Roly is the man..

Here's the thing I was referring to. It holds the two by to the waler, to make the stiff back.

 

If this were that show "What's my Line", I'd go with Roly...or was it "I've got a secret"...I do however remember Dorothy Kilgalen and her stringy neck...

 

If I can't remember the shows how the heck am I supposed to remember horizontals, walers and verticals...cheez...

 

 

Bingo, Roly has it down pat and Gene Howe has the exact clip that is used to hold the stiff back timbers to the walers.  Good show this morning.

 

 

By the way, I ended up in the ER. this morning with a torn muscle in my right rotary cup of my shoulder. It will take a few days before we know if I have to have surgery.

Sorry to hear that Ralph, they should have pulled you out in the 6th inning instead of leaving you in through the 9th.

Say what was the answer to last weeks quiz?

Stiff backs is what we used  on the taller fall formwork,  like the 10'  and 25'  stuff.    They had their own wire clips, about twice as long as the whaler wires.   Usually, we'd nail the wires off to the 2xs.   We'd try to put a stiff back on a seam.   Usually every 4-8' spacing.   Sometimes, we'd use a bolt system that went through the walls.   with a doubled whaler and a doubled stiff back.   Turnbukles still were nailed to the whalers.    We'd get the wall lined up before the pour, and then come back and line it up after the pour.....10' tall wall @ 12" thick....takes a bit of work to move them back into straight....BTDT.

We used the long tailed snapties, or she bolts and cat heads.

That's too bad, Ralph. Sorry to hear that. Hope it can be alleviated without the knife.

Ouch. Very sorry to hear this Ralph. Hopefully since it's the muscle it will heal and through rehab be OK. If it was/is torn cartilage, then surgery will likely be required. Let's hope it remains with just the muscle. Regardless, still painful...take it easy as possible. 

Ralph, I sure hope you don't need that surgery. I had it about 7 years ago when i was a young 62, and while the surgery wasn't bad at all...the recovery time really sucked. Hoping for good news.

Ralph, bummer about the shoulder.  Here's praying that R&R will be the fix.  Like Fred said, the recovery time is brutal.

Get some rest for that shoulder Ralph.

Sure hope you can heal without surgery.
