  • Patent number: 8607517
    Abstract: The foundation structure includes a plurality of structural members. A first end of each structural member is coupled to a central shaft. In appropriate soil conditions, the foundation structure is buried in the soil and the soil itself constrains the mass at the base of the foundation and keeps it from moving. The foundation structure is made of structural components comprises a material, including concrete pre-cast concrete, cast-in place concrete, reinforced concrete, pre-stressed concrete, pre-tensioned concrete and post-tensioned concrete, for resisting the expected forces transferred from the tower.

  • Patent number: 8590276
    Abstract: The invention concerns a tower element for a tower, preferably for a wind power plant, where several tower elements with an outer surface and an inner surface are mounted on top of each other, where the periphery of the tower element is made up of a number of segments provided with inwardly facing flanges at the longitudinal sides, the flanges being connected to corresponding flanges on laterally arranged segments. The individual segments are made with an overlap on the outer surface in the transverse joints and with a butt joint at the inwardly facing flanges. By the invention there is achieved flexibility in production and during transport and mounting. With an overlap on the outer surface between two segments, mechanical joining can be performed between two segments in transverse direction. This mechanical joint between two segments results in a more stable construction and a rigidity substantially corresponding to the rigidity that may be achieved in segments joined by welding.
