On Saturday, my father and I cemented the supports for the solar sail. The columns are each 3 m long, have a diameter of 121 mm and a wall thickness of 5 mm. We can welding at the top of a lid and a Öese for suspending the turnbuckle. At the lower end, we like to see on the second picture is of Clubs, 4 pieces of flat steel weld then the columns can still galvanize.
have to align the columns We created a holder of the battens, so that the supports at the right angle, parallel to the terrace and the Öesen at the same height.
Below are the foundation stones for the concrete supports on the right height and they are tied to two wings of rebar with wire, so as not to slip when pouring the concrete. We have a good cubic meters of concrete needed for the foundations.
Today was the installer of awnings company with us and has set the two attachment points in the wall. This can be seen on the following image to the right of the balcony on the suspended turnbuckles.
The mechanic has not measured the exact size of the sail, so that this can now be made.
I have now dismantled nor the holders of the supports.
