Please use the code=cpp tag to post code!
I then suggest to use English variable names, so someone not speaking your language will immediately understand your code, it's also kind of what everyone does.
We won't be programming your game, so I don't know how we can help. You first need to figure out, what you want to do exactly. "How to load a map?" just doesn't say anything. Maps can be 3D, 2D, tilebased, isometric, etc. etc. - there are endless possibilities!
You need to first comeup with what you want your game to be and then you go and look at the documentation of SFML, use google and your brain and think about how you could implement it. If you have basic knowledge in C++, then you're quite comfortable with OOP, right? So you can easily come up with a nice OOP way of handling objects etc etc.
