As suggestions from me:
- Anchoring at the top: support in front of the beam, connection plate on the support with holes for Spax screws
- Anchoring at the bottom: open pavement in the area of the supports, small individual foundation 250mm deep with 500mm thickness
I would personally build the supports from galvanized steel. This way, the construction can initially remain uncovered without starting to rust. Since there is hardly any wind load and only small support spans, an HEA 100 to HEA 120 range will be completely sufficient.
As a wall, you could use sandwich panels (regardless of whether laid horizontally or vertically). This would have the advantage that you have some insulation, which however doesn’t add much in combination with PVC roof light panels anymore.
Alternatively, single-sheet trapezoidal sheets. But depending on the development plan, such walls are not allowed everywhere
p.s. den manta habe ich geschlachtet da ich teile für meinen anderen brauchte.
The main thing is to preserve one old sheet metal on the street!
