Fastening Angle Bracket to Concrete Threshold

[naikon]

Hi, the old threshold iron for the garage had rusted away, and now I plan to attach a new angle iron.

I don't have the energy to do a complete recasting of the edge, so I have cut off the reinforcement on the new threshold so that it becomes like a regular angle iron.



However, I thought of casting a repair for the actual concrete edge so that it forms a good 90-degree angle. The edge is almost completely crumbled, as you can see.

But how do I best attach the angle iron to the concrete edge afterward? I drive in with the car a few times a year, so it doesn't have to withstand daily loads.
Just glue it with construction adhesive?
Or drill holes and use about 3 or 4 concrete screws or expansion bolts?

It will never hold long-term not to secure it permanently.

It will never hold long-term if it is not cast in place..

Alright, then I have to bite the bullet and redo it. What happens if you screw/bolt it down then?

That it is not fixed firmly, and every time you put weight on the iron, it moves and then the galvanization on the iron disappears and rusting begins..

That it doesn't lie rigidly and every time you load the iron, it moves and then the zinc disappears from the iron and the rusting begins..

Ah ok yes that's probably correct. But as I said, it will probably only be loaded with a car a few times per year. In the worst case, I'll have to plan to redo it in a few years then.
