  • Tower internal-equipment bracket structure and wind turbine generator
    Patent number: 8573950
    Abstract: A tower-internal-equipment bracket structure with a welded structure that can ensure a fatigue strength classification equal to or greater than that of butt welding (BW) or that requires no welding and a wind turbine generator provided with this tower-internal-equipment bracket structure are provided. In a tower-internal-equipment bracket structure provided inside a pole-type steel tower, employing a cylindrical shell (11), to support tower internal equipment, a ring-shaped member (20) having a protruding portion (21) toward the tower interior is interposed, by means of butt welding (BW), between divided portions formed by dividing the cylindrical shell (11) at a desired position in an axial direction, and the protruding portion (21) serves as a bracket-member support portion for the tower internal equipment.
