As far as I understand, many people do it this way. They put threaded rods into the reinforcement when pouring. And then they put the wall batten on them and screw it on top with nuts. This is quite convenient.
But here's a question – how often and what diameter studs are needed? Specifically, I have a building measuring 10.5 x 10 m, the roof is hipped with a slope of about 20 degrees. But I would like to understand the general mechanism of calculation.
