Model Under Way

This is my model for the project. It is a model of how the roof connects to the purlin and how the purlin then connects to the rafter. This is it before i paint in and also before i have fully put it together. I disconnected the purlin from the cleat so it made transportation easier but i will bolt this back on when i get it into uni.

This the I-beam and cleat before if has the purlin and the rest of the roofing structure attatched to it. I got all the measurements from a steel mass book i got from one steel or metalland (they seem to be the same thing as far as i can tell). I found it hard to know which I-beams and size purlins i needed to use as it was all done in how many kg per meter not in actual spanning distance. So i just took a stab as i did not know how to work out how many kg per meter my roof would weigh.

This is just the I-beam again form a different angle.
This it the roof part of the model looking from the top. I know that this is actually incorrect as this roofing would not be appropriate on this size building as the corrigations are not big enough to drain the water fast enough. But this was the closest sheet roofing i could find to what would actually be used and was something i could afford.

This is a picture of the z-purlin, mesh and insulation. The z-purlin still needs to be painted but after it is painted it will bolt to the cleat which it attatched to the I-beam. The insulation is also not the correct insulation for this type of construction as it has no sarking on it. But to get insulation with sarking on it you had to buy a $90 roll of it which i could not afford where this insulation was much cheaper. Also the piece of wood you can see to the right of the picture would not actually be there. It is just there to hold the mesh and insulation to the sheet roofing otherwise it all sages and doesnt look very good.
