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.

Trusses from Thomann, or not?

Then, yesterday:

Do you know web shops that advertise goods as "in stock", or "in stock in 2-5 days", and the moment you ordered suddenly appear to have no stock, and delay delivery? www.thomann.de is such a shop. The moment we ordered one of the items had a 2-5 days in stock time, but when I looked later "June 15", that is in 3 weeks. Plus delivery time.

Of course you at first hope that is because of your order, so their stock is depleted, and the new stock will ariive in 3 weeks, but no.

"Unfortunately, the supplier has delay with this item."

The terms&conditions of Thomann state that "In such a case, the customer shall be notified immediately", but even that: no. I just happened to look, and saw the new date. For the time being I think Thomann is an untrustworthy party that shifts its responsibility to its supplier. If I happen to see the goods somewhere else I'll cancel the order. Assh*les.

Pergola and Trusses

Now the terrace is shaping up it's time for a pergola, for shadow. You can build pergolas in one hundred and a half way. It seems that we are going to do something with aluminum trusses. You know trusses, pop concerts, and so on. Aluminum alloy beams made of tubes with zigzag joints, like:

Those who likes it can check out the GlobalTruss website. A delicious meccano system with liggers, corner pieces, etc, in all sizes and shapes. And even arches, ideally suited for romantic bowers.

The intention is now to fidge a construction in front of the house, where at the top a piece of fabric is positioned for shadow. Here's a simple impression of a 12 meter long pergola with the "deco" truss variant F14, 10x10cm, and also with the larger (and more expensive) variant F24, measuring 29x29cm.

Dont forget to imagine some climbing flowering plants.

This is 18 meters, 3 sections of 6 meters:
