Fitting a UB.

[trialscot]

HI,
I'm taking down an internal brick wall and replacing with a UB. All permissions and calculations in place.
What's the method of packing under the ends to level the beam off at the right height?. I'm thinking of holding it up against the joists with a couple of acrows and building up under it with slices of paving slab or something similar. Can I use sheets of steel?. Should the UB be bedded in mortar?.
Any advice welcome.

Just done a search and found most of the info.
My SE makes no mention of padstones just a 300mm bearing at each end. It's a 4m beam, 203x102, is there a standard padstone size for this?.

padstone sizing is done by the s.e. we tend to use cut to size builders lintels as these usually correspond with the existing brickwork.

a typical padstone would be at least 100mm past the steel each side and be three courses deep.

The beam should sit directly on the padstone, and if you have to bed it up, then it has to be a strong mix - minimum 2:1 I would say and a full bed.

But you would be better off bedding the padstone up - in which case you can use normal strength mortar

i personally find it easier to get the ub in place and all levelled up the cast a padstone in situ then it can't be wrong

S;late is usefull for packing if the set out of the padstone goes wrong
