We will be installing a structural UB in a few weeks in the rear wall of a existing dwelling.
The beam is approx 750kg. The engineer has calculated the beam, and has told us it will have a deflection of 15mm, the span is around 8m.
Does anyone have any advice on installing this, as I am concerned about the deflection?
We have installed hundreds of beams, we do this most weeks, so completely fine with the building practice in doing so, but I can’t get my head round the issue of the beam deflecting under load when the props are released, causing fairly serious damage to the property.
I have thought about releasing the props slowly over a period of time, but the eventual load will still be the same, so may not have any effect.
I am also considering discussing getting stiffness welded in the web of the deadlink help minimise the deflection.
Any advice on how to handle this will be great.
A tidy job is a happy job.
