I’m opening up the side of a room – creating a span of 2450mm. At one end the beam is supported on a brick pier (remainder of existing wall) creating a 300mm bearing, at the other by going into the wall perpendicular to it – 150mm bearing. Walls are 225mm solid brick (commons). Beam is two 178x102 UBs side by side.
My drawing from the structural engineer shows one p.c.c. padstone spreader 675w x 150l x 150dp to go into the wall perpendicular to the beam – but the wall is 225 thick. Should it be situated in the middle of the wall, the side away from the span or nearest it? Or should it just be as big as the wall thickness?
The pier has a p.c.c. padstone 225w x 300l x 150dp – presume this is right and it doesn’t need to be any longer the bearing of the beam? Also – a few quick web searches showed some BCO guidelines suggesting a minimum of 225 depth for padstones supporting beams of this gauge spanning over 1.8m.
Would it really matter if I made the padstones 225dp anyway – just in case?
Many thanks,
M
