Planning to build a canopy that will be approximately 4x2 meters, with a slope of about 20 degrees and posts at the corners as well as in the middle of both long sides. The roof will be corrugated plastic.
Along the high long side is a fence with 95x95mm pressure-treated posts, along the low side the roof will rest on 95x95 pressure-treated posts, and there won't be any walls there or on the "gable ends".
So there will be 3 beams between the long sides and two beams along the long sides (green), and then an as yet undetermined number of beams between these (blue).
I'm considering what would be suitable to use for the rafters of the roof construction. Snow zone 1.5 (but 200 meters above sea level so rather zone 2, there's usually significantly more snow here than a few kilometers away).
Will 45x95 mm work? Is there a place to calculate for a canopy like this?
45x95 C24, center distance 300 mm works. I have then planned that the roof joists lie on the long side as below.
Thanks! And nice drawing compared to my scribbles... Unfortunately too late, I've already been shopping...
Changed the construction so that it will be roughly as you drew, but with 8 roof beams and then "battens" on top of that. My original idea was to have the longitudinal joists between the roof beams, but realized that it involves significantly less measuring and sawing if I have more roof beams and a thinner longitudinal batten on top of them instead.
At the risk of using the terms a bit wrongly/carelessly, it will be something like this...
Pillar: 700mm, 4" post iron (the concrete should protrude about 20cm above ground level, hence 700mm)
Posts: 95x95
Header (along the long sides): 45x170
Roof beams (on top of the "headers"): 45x145, cc 800mm
Battens (on top of the roof beams): 45x45, cc 400mm
