In this case, the question is about the installation of a house of 2.4 x 6.0 m. However, in the long run, I expect that if not a hut, something else will stand on the same. The situation is complicated by the presence of the slope with a difference of height 40cm.
In the ground poles – at 1m with a sand cushion and the expansion of the bottom. Pillars with fittings D = 8mm. In the ground – a round hole with a drill 200mm. On top – the formwork (boxes) of boards 200x200, with a height of 700mm.
I think it would be a good idea to tie the posts together for rigidity. There is an 80 channel and somewhere the same level of angle. Question: How do I put the channel (angle tube)? Feet or wide (narrow) shelf up? Do I have to attach the embedding bars and weld the channel to them? After all, the design is not heavy, and the channel was treated solely as a strapping, without the function of support for the house.
Nevertheless, it turns out that the channel performs the role of the beam. Maybe install it below rather than on top of it?
I was thinking of just inserting the channel into the boxes. To make sure there are no voids, to sink the metal into the mix just poured...
What is wrong with my plan? Or how best to complete the strapping of the posts already ready for concreting, with or without the use of the channel bars, with minimal cost? That said, there are difficulties with welding.
