Abstract
A strengthening structure for a wind turbine blade includes at least one first reinforcement part adapted to be connected to a first blade part of the wind turbine blade, and at least one second reinforcement part adapted to be connected to a second blade part of the wind turbine blade. The strengthening structure is characterized in that the at least one first reinforcement part and/or the at least one second reinforcement part includes an adjusting mechanism enabling that the first reinforcement part and the second reinforcement part are displaceable in relation to each other, at least during the assembly of the wind turbine blade and wherein the adjusting mechanism includes a force mechanism capable of forcing the first reinforcement part and the second reinforcement part away from each other. A wind turbine blade, a method for assembling a wind turbine blade and a use thereof are also contemplated .
