How do you "attach" the posts at the base? Let them stand on rock/gravel and assume the pressure keeps them in place, or be super serious and drill in something like a post shoe into the rock?Larsa said:
I would preferably start the whole process by exerting upward pressure on the beam in some way and then casting a pier on the ledge. There is about 40-50 cm between the top of the rock ledge and the beam, so I don't know if it's easier to cast or build something. Does, for example, a 25 cm concrete tube with two rebars drilled 15 cm into the rock ledge suffice?
It is enough to place them on the ground/rock.
What you describe works excellently. You can fix the casting pipe in place by screwing struts into it so it stands still.
Then, wooden wedges are always good. You can cast close to the line and then after it has set, drive in wedges to get good tension on the load beam. Ready-made wedges are available for purchase at the building supply store.
