Abstract: The invention relates to a support construction (1) for fabrication equipment of microscopic structures, comprising a monolithic foundation body (3) on which, for fixing the fabrication equipment, a fixing element (6) is provided comprising a resilient element. The fixing element further comprises a rigid element (10) whose rigidity decreases significantly when applying a dynamic force to the fixing element which force exceeds a predetermined threshold value. The support construction is further designed such that, regardless of the size of the dynamic force applied to the fixing element, a static force applied to the fixing element is substantially transmitted via the resilient element to the foundation body.

Abstract: The invention relates to a mast (10) for a wind turbine, which mast tapers towards the top and comprises at least two superposed annular mast sections (12, 14, 16, 18, 20). Every annular mast section consists of a plurality of prefabricated wall parts (A, B, C, D, E, F), wherein at least a part of which has a curved section, at least the curved sections of prefabricated wall parts in different annular mast sections having at least identical cross-section.

Abstract: A wind turbine, comprising a stationary vertical mast (or tower) on which a moving part of the wind turbine is arranged, which mast is at least partly composed from prefabricated wall parts, with several adjacent wall parts forming a substantially annular mast section. The invention also relates to a mast for a wind turbine, to a prefabricated wall part and to a method for building a wind turbine.
