WIND TURBINE ROTOR BLADE AND METHOD FOR ASSEMBLING A WIND TURBINE ROTOR BLADE

Provided is a wind turbine rotor blade with a longitudinal direction, at least one first rotor blade section with a first front side and one second rotor blade section with a second front side and a separation point between the first and second rotor blade sections. The first and second front sides abut against each other at the separation point. The first front side has a plurality of first recesses, and the second front side has a plurality of second recesses. Further provided is a fastening unit, which is designed to fasten the first and second rotor blade sections to each other at the separation point. The fastening unit has a plurality of first inserts made out of metal, which are arranged in the first recesses, and a plurality of second inserts made out of metal, which are arranged in the second recesses. The first inserts each have a first end and a second end. The second inserts each have a first end and a second end. The first ends of the first and second inserts are each arranged at the separation point. The fastening unit has a plurality of clamping units, which are suitable for bracing the first and second inserts against each other, wherein the respective first ends of the first and second inserts abut against each another and are braced against each other in the braced state.
