anchoring the arcs of our greenhouse
Good evening,
the structure for our greenhouse has arrived. While the previous owner claims that the arcs just need to be set on flat ground, I have a doubt, that the greenhouse can withstand the winds in this way. The arcs end in steel-boards with a “Z-profile”, like in this drawing (I hope you use a mono-spaced font for the news): | top right _________ left | /________/ | | | | | | | | | ( ) | | | | |________| | \__|_|__ /________/ | \ | bottom Does someone know this kind of greenhouse structure? The profile has certainly a meaning and my wife and me consider sinking the boards low enough into the ground to put weight on them; either stones or cement. The whole greenhouse will be 6x20m (120m²) with vertical “walls” up to about 1.9m, which means a considerable weight, but also a considerable surface. Even if I choose an intelligent orientation and a good compromise between insolation and wind resistance, some additional anchoring should be needed, I guess.
