Pergola - trusses - blocks (new!)

Our pergola is made with aluminium trusses, and basically not attached to anything. It's not light in total, but with stiff winds we've seen the whole structure being lifted up a bit, and banging down again. We did not like that much. We prefer not to have a totally fixed permanent structure. Both because we don't know exactly how and where, and want to be flexible. But also because they tax fixed structures like pergolas.

So, ingenieur Jansen went to work and made concrete blocks with a threaded M14 rod inside the concrete. Holes in the bottom plates of trusses, rings, bolts, and ready.
