OldieNewbie Posted August 13 Share Posted August 13 Hi all, I was walking past a house in my locality that is having renovation work done. The back of the house has several red pieces of steel passing through the back wall. What is the purpose of these? Is it to hold the wall and internal walls in place? (I have attached a file picture for better explanation) Who would decide the location of these? Is it down to the contractor or the architect? Is there rules of thumb in regard to the steel being used, i.e steel should be a certain grade and twice the width of the wall it’s carrying etc? Cheers, Link to comment Share on other sites More sharing options...
ProDave Posted August 13 Share Posted August 13 Yes those are temporary supports holding up the back wall while they insert that big steel beam then it looks like they are going to knock out all or part of the back wall downstairs to join through into the extension. A structural engineer would normally specify that. 2 Link to comment Share on other sites More sharing options...
saveasteading Posted August 13 Share Posted August 13 Absolutely has to be by an SE. Rules of thumb have their place at feasibility stage, but this has to be calculated to suit the individual building. Then the geometry have to be vondidwred eg the beam fits and is below the walls. Then the walls supporting the beam need strengthening, maybe even extra foundations. 1 Link to comment Share on other sites More sharing options...

"Geometry has to be considered" would have been a better phrase. Vondidwred, an obscure term used in vonstruvtion for vombining practicality with svienve.

Super_Paulie Posted August 13 Share Posted August 13 just dont do what my builder did and install the supports onto my old chipboard floor to hold up the rest of the house with some knackered bits of timber... "Rough" would be the word. Horribly dangerous would be another id imagine. Link to comment Share on other sites More sharing options...
