Hi,
I'm wanting to explore the possibility of replacing a floating chipboard floor with a screed for a house built in 1999.
The subfloor is block and beam but the beams appear to be a lot less beefy than their modern equivalent. From the measurements I've been able to do they appear to be 35x150x80mm (in cross section; the longest span is 3.6m). For modern designs there are tables online which give an indication of span VS load but I can't find any similar examples for (or indeed reference to) beams of this size.
Has anyone came across similar before or know where I might look for technical specs. I appreciate that this would differ between products/blocks used but I'm just looking for a starting point. For reference the beams appear to have 3 reinforcing rods from what I can see.
So far the closest to these dimensions I have been able to find is this product:

I'd be greatful for any help on this. Thanks.
