HORIZONTAL JOINT ASSEMBLY BETWEEN TWO TELESCOPIC WIND TURBINE TOWER PORTIONS AND METHOD OF INSTALLING SAME

摘要

The present invention relates to a horizontal joint assembly between two telescopic wind turbine tower portions comprising the head fraction of a lower tower portion (1), the base fraction of an upper tower portion (2), and anchoring means (6) for anchoring said head fraction to said base fraction, said upper portion (2) being intended for being lifted above said lower portion (1) along the inner face of said lower tower portion (1); said horizontal joint assembly further being characterized in that said head fraction is provided with a thickening (3) in its inner face and in that said base fraction is provided with a thickening (4) in its outer face, such that both thickenings (3,4) substantially contact one another when the upper segment is lifted.
