The proppings are screwed onto the concrete slab for a temporary brace stiffening. The line of slots on the bottom of the tilted up panels allow the concrete slabs to join up with the panels, allowing the panels to act as a structural component to support the whole building. When this is done, the propping will be removed.
This photo shows how a tilt up panel is being lift up by a crane.
I found out that the proppings are actually installed during the lifting panels take place.
The steel bars could be allowing other joinings to be installed sometime later during the construction. Also notice the small slots in between each panels, these slots actually allow steel plates wielded to join the tilt panels together.
