When a picture tells 1000 words. The images are self-explanatory. We use screws or welding to hold them together. Preferably screws as explained in previous sections.
Note that at the end …. (where we don’t have a building below) the metal beams need some X,Z,V shaped REINFORCEMENT to make it stronger. Especially where its heavy snowfall. It’s quite a big opening. It needs it. Didn’t draw it. We don’t get lost in details :))
It’s not a do it yourself thing. Your certified, licensed engineer should calculate the shape and size for your given climate and wind profile. Just giving you the guidelines … what type of construction method to follow.
Laughing meanwhile. Most will overcomplicate it :). They will say it can’t be done … It’s foolish. It will break etc. And they will come up with a drawing … a brick house with 10 cm polystyrene on it.
Don’t be cheap. Find a really good engineer that is specialized in metal constructions … and pay it like a king. It will make your money back 10 fold. It seems complicated at first but actually it solves the air movement at keeps water and moisture away from insulation and the house itself.
Basically we push a false façade away from the building. This way hot air can leave immediately in the summer and the cold winds will be stopped as well. All of it bone dry. Even while it’s raining. The created space its not empty. A big chuck would be occupied by the shaders. The shaders are for privacy and for blocking the summer sun maybe winds hitting the glazing.
