I am soon to replace 2 large 7 facet bay windows, the ground floor one though has me concerned, it has 1138mm projection, 3000mm opening, 1750mm height.
I have calculated the ground floor bay has a combined load of 3 tonne sitting on this old wooden frame, maybe some of this load is supported by the floor above.
The barrel is single leaf brick, with timbers running vertically between the upper and lower floor window frame transoms.
To get the one piece welded uPVC sill in place and start assembling the window - all the old load bearing frames will need to come out - which is a scary prospect with 3 tonne above my head.
Attached is an image of acro's being used to support a bay wall.
I am interested to know how I would support this, in my mind 5 acro's used around the base perimeter of the brick bay wall would suffice, at a slight angle it keeps the bay pushed against the return wall - and props it up at the same time.
I also see the first floor Joists act as a sort of cantilever - running the length of the bedroom, and project out over a steel beam (which spans the opening) - these joists finish inside the single leaf brick wall - with brick laid on top and around them - could I assume that some load is taken by these floor joists ?
