Thread: Acrow prop, how to use? and advice please

once you get the acroiw prop, i think it will be self explanatory how to use it - though a tip is to always secure the top with nails through the plate holes, and if it is against a painted surface then the prop is nailed to a piece of 4*2 so the weight is spread wider than just the plate of the acrow prop - BTW clockwise is to to tighten (ie lengthen) - if its anti clockwise you have it upside down

that post looks suspiciously like its bolted to the wall to me and that is where the weight bearing is - regardless, you might be better advised to make the existing concrete base flat and stable (ie remove cracked and broken concrete), and either ramset concrete anchor or chemset in 2 bolts to hold it down - using the post brackets that have a base plate and 2 holes for securing. Tie down is equally important to weight bearing so both must be considered.

Thankyou pharmaboy2.

Further pictures added for clarification. (the pics took ages, dialup sux)

I have had another look at the acrow prop. It has been let sieze up, and has filled with sand. I have got it moving enough to work out what bits I need to get unseized so that I can use it . Guess who I will not be lending anything else to again.

Ok, the bottom of the post, here looks like it has two bolts running from it into the concrete.
The "T blade post stirrup" from here was something like I was thinking of using, except the one that I want to use has a "U" at the top for the post to be bolted into. I was thinking if I just concrete the bottom half of this bracket into the concrete when I do it, that should hold it pretty well, as long as the concrete p[atch is tied back into the existing concrete pretty well.
Ok, a pic of the back verandah, (yes, is is now pretty bad, has slowly been degrading for many more years than I can remember) The timber uprights between the louvre windows have rotted out, and are basically holding nothing.
I have recently noticed that between the post and stonework a gap is appearing that hasnt been there before, and the concrete corner has finally cracked off.

Now, regarding the acrow prop, do I just use that to lift up the beam that the post is attatched to, I assume that I will need some diagonal bracing to stop any potential sideways movement of the verandah.
How long after the concrete is poured would I need to leave the weight off for, eg, leave the acrow prop set up?

Nice tip for siezed up metal parts- spray them or if possible soak them in Diesel fuel for a day- then coat with blue grease. works a treat.
