Olf Posted December 16, 2020 Share Posted December 16, 2020 'The 50*50SHS 2.5mm thick S275 steel should be fixed to the existing concrete sub wall below with a 6mm S275 steel base plate and 2 no. M10 bolts.' says structural engineer report. Surely that will make a cold bridge - should I be concerned at all, considering relatively small cross section of the post? Is there any way (non-compressible pad?) used to avoid such thermal bridging? Link to comment Share on other sites More sharing options...

Russell griffiths Posted December 16, 2020 Share Posted December 16, 2020 What is that holding u, as it looks smaller than anything I’ve ever used in house construction, apart from a lightweight carport. Link to comment Share on other sites More sharing options...
Olf Posted December 16, 2020 Author Share Posted December 16, 2020 @TonyT - big thanks, 'Structural Thermal Break' is what i need to shop around for. 1 hour ago, Russell griffiths said: What is that holding 127*76 RSJ supporting a half of the first floor (marked red). Currently there is 50x50 steel box profile at 0.37m from the central wall (believed to be a temporary support, left hidden inside the wall) and 90x90 wooden post at 1.52m from central wall. To accomodate the wardrobe I need to move the wooden post and SE calcs showed (I trust) that single 50x50 on the side of the wardrobe is enough.
