  • Patent number: 10513866
    Abstract: The present invention refers to a wind turbine tower and a respective foundation base, comprising a central column with a central column foundation, upper tensile structural elements with upper ends attached to a tensile structure element bearing portion of the central column and tensile structural element foundations around the central column foundation. The structural system is characterized in that each lower end of the upper tensile structural elements is attached to a respective compressive structural element that connects said lower end of the respective upper tensile structural element with a compressive structural element bearing portion of the central column and that each lower end of the upper tensile structural elements is attached to a respective lower tensile structural element that connects said lower end of the respective upper tensile structural element with one of the tensile structural element foundations.

  • Patent number: 8955274
    Abstract: A windfence supporting tower with tension-integrity, includes a tubular metal tower having a central tubular post and four inclined tubular structural tensile elements attached to the post via the coupling ring and the lower ends attached to the free ends of a yoke of compression tubes, which is in turn attached to the post by the reaction flange of the yoke, further receiving at the free ends of the yoke four vertical tensile structural elements which are tensioned and anchored to the ground through four independent foundations located around the foundation of the central tube. These vertical ties pull on the connection point of the yoke and in turn the inclined structural elements connected to the coupling ring, thereby providing stability with tension-integrity, which is the main feature of the present supporting tower for absorbing forces caused by the wind.

    Abstract: The present invention relates to a windfence supporting tower with tension-integrity, comprising a tubular metal tower comprising a central tubular post (1) and four inclined tubular structural tensile elements (2) attached to the post via the coupling ring (3) and the lower ends attached to the free ends of a yoke of compression tubes (4), which is in turn attached to the post (1) by means of the reaction flange of the yoke (5), further receiving at the free ends of the yoke (4) four vertical tensile structural elements (6) which, by means of tensioners (7), are tensioned and anchored to the ground through four independent foundations (8) located around the foundation of the central tube. These vertical ties pull on the connection point of the yoke and in turn the inclined structural elements connected to the coupling ring, thereby providing stability with tension-integrity, which is the main feature of the present supporting tower for absorbing forces caused by the wind.
