Hi,
I'm installing an RSJ so I can knock through a 100mm brick internal wall which supports
1 set of floor joists above and a 1st floor brick wall.
(I've installed 3-4 RSJ's before but always with new piers, etc)
The wall is 3750mm wide, the opening is to be 2400mm and the steel is an 8" x 4" at 3500mm length. The engineer has spec'd it overside so that instead of having the usual 150mm-200mm overhang on pad stones/prestressed lintel, there is the best part of 600mm overhang of steel bedded directly into the existing brick work on a bed or dry 3:1 mortar.
The issue I have is that because of the configuration of the brick courses, if I lay the steel on the nearest whole course of bricks, it's leaves a gap from the top of the steel to the underside of the brickwork of 50-60mm.
Is this gap too large to pack out with slates followed by mortar pointing? I could try and lay another course of bricks on the bottom of 30-40mm thickness, but I don't know if this would be worse then just a large packed gap?
I'm waiting to hear from building control but they are very busy so am trying here first.
Cheers.
