Can I get an acrow prop longer than 4.85 meters?
It's about 5.1 meters from my downstairs floor to the upstairs ceiling I
want to prop up, but I may have to pull up those downstairs floorboards
and rest it on the earth.
I dont trust the upstairs floor to hold all the weight when slipping a
new lintel under the beam.
If you are only propping up the ceiling or roof, the upstairs floor is more
than strong enough, trust me, we used them last year, from December to March
holding up the roof of an house we had taken the front elevation out of (we
had to wait for the bricky to build the downstairs walls, then for calcs for
the steel beam over for the wall between downstairs and upstairs, then order
Lay a plank inline with the floorboards so that the prop is utilising
several joists, and also make sure the bottom of the prop is directly on top
of a joist and all will be well.
You can get long acrows but they tend to be unstable
Can you not fix two Acrows together, end to end? I'm not sure whether the
plates have holes for bolts in them - but if not, you could use G clamps.
But - as others have said - that may not be all that stable!
That would be a very dangerous option. It is buckling rather than
stability in general that is the real problem. The combination of 2
Acrows linked end to end would be far weaker than the rated capacity of
the individual Acrow.
Thanks everyone for the discussion.
i've sawed away some plaster from the ceiling
using my bosch PMF (as mentioned here a year ago)
and fitted an acrow from the downstairs floor to the bottom of a joist
of the upstairs floor.
I'm not worried about it buckling.
I will look at it for a few more days before removing the broken lintel
(which holds up half the roof)
