Abstract

A segmented wind turbine rotor blade includes sleeve-shaped pressure pieces arranged between rotor blade segments, each of which is mounted on a connecting bolt. Each pressure piece includes one or more cylindrical sections and a tool engaging section for an assembly tool). Each pressure piece is connected to a corresponding connecting bolt in a form fit manner, so that a screwing force can be applied to the corresponding connecting bolt via the assembly tool via the pressure piece. A diameter of the cylindrical section(s) is less than a diameter of the tool engaging section. Each two adjacent pressure pieces are arranged rotated by 180° relative to one another.
