Precast segment for wind turbine tower and method for building a wind turbine tower using said precast segment

摘要

Precast segment for wind turbine tower especially designed to be used in wind turbine towers installed in cold climates, and which comprises joint flanges (3) showing a configuration intended to establish the boundaries for forming the joints (4) between said precast segment and an adjacent precast segment and which comprises conduits (2) provided with an inlet (9) and an outlet (10), situated in the proximity of the joint flanges (3) of the precast segment intended to house some heating cables (1) that generate heat. The method comprises the use of the described precast segment and the stages of introducing heating cables in the conduits of the precast segment, applying current to said cables and removing the cables when a filler material used in the joint between precast segments has set.
