I'm not getting anywhere googling on this, not exactly DIY either but what
the hell.
Does anyone know the technical term for those tie rods used on old buildings
with bulging walls etc.?
More specifically I'm interested in how the steel bars were heated, then the
nuts tightened, and on cooling produced the inwards tension.
Was it just steam jackets or was it higher temperatures from an exothermic
chemical reaction.?


When we fitted them to our house, there was no heating - the structural
engineer simply specified a torque to tighten the nuts to, that's all.
