In the known framework standing structure for the foundation of a wind turbine, three pairs of pillars are provided, which each consist of two pillars that are inclined and bent twice and which intersect above the centre of said pillars. In order to be able to bear greater loads and to compensate torsional forces better, in the framework standing structure (01) according to the invention, a further pair of pillars (15) is arranged in front of or behind each first pair of pillars (12) consisting of first pillars (02) that intersect at crossing points (13), the further pillars (16) of which further pair of pillars intersect at a further crossing point (19), which is however situated below the centre of said pillars. None of the first and further pairs of pillars (12, 15) touch each other. Owing to the diagonal arrangement of the pillars (02, 16) all the effective forces are largely distributed uniformly to said pillars, the effective forces being distributed to two levels owing to the contact-free duplication of the pairs of pillars (12, 15). The centre of the framework standing structure (01) remains free. It can absorb both torsional forces and bending forces particularly well and distribute them uniformly. Together with a very low weight of relatively few, structural elements that can be readily pre-assembled, particular advantages are produced for the offshore installation of wind turbines. |
