Hi,
Seeking clarity on above before engaging engineer for calcs.
I have built two houses so building is not new to me, I have built a steel boat so steelwork is also familiar but I seem to have a mental block when trying to marry the two.
The job entails widening two picture windows in a 10" conc block cavity wall such that they meet at the corner of the building. The existing corner/column of block work ( approx 1m x 1m wide) will be replaced by a 4/5" steel box column supporting two inverted T section steels ( 8" flange) which will sit under the existing conc lintels, the web section inside the cavity.
My thought was to remove the block work down to dpc in way of the corner, pour concrete L shaped seperate pads (thus keeping the cavity) and bolt the sole plate to these new pads, block work then made good around them. New cill height would be 450mm off dpc and new span is 2.2m approx, the column sitting mid way on the wall. I am not seeking calcs for the steel on this but more a better idea of the methodology of introducing the steel column to the existing building.
Does this appear reasonable to you steelmen out there or am I missing the obvious once again. Any thoughts or advice would be most welcome.
Thanks
