Abstract:
1. A method for assembling a structure formed from several structural modules disposed on top of each other or for assembling a wind power plant, wherein a first structural module of the structure is initially erected, and at least one further structural module is subsequently disposed onto the first structural module or onto a previously erected structural module by moving the at least one further structural module in an upward direction using a lifting gondola to a level of an assembly position thereof such that contact between the lifting gondola and the previously erected structural modules is avoided during movement of the lifting gondola, the method comprising the steps of: a) preparing a plurality of self-supporting auxiliary mast modules for erection parallel to and laterally of the structure to be erected, each of the self-supporting auxiliary mast modules having a length which approximately corresponds to a length of a respective one of the structural modules; b) detachably connecting each of the self-supporting auxiliary mast modules to each of the structural modules to form overall modules, each of the self-supporting auxiliary mast modules thereby being structured and dimensioned to accept a weight of the respective overall module; and c) sequentially lifting the overall modules, each formed from one of the plurality of self-supporting auxiliary mast modules and one of the structural modules, in an upward direction using the lifting gondola along a self-supporting auxiliary mast of previously erected auxiliary mast modules to a level of assembly position of the respective structural module; and d) repeating step c) until completion of assembly of all structural modules, wherein, during displacement of the lifting gondola along the self-supporting auxiliary mast, contact between the lifting gondola and the structure is avoided and an introduction, into the structure, of normal forces, transverse forces, twisting forces and bending moments generated by the loaded lifting gondola and by wind acting thereon is prevented, wherein each structural module has a height which can be adjusted relative to each respective auxiliary mast module, each structural module thereby being disposed at a higher level than each respective auxiliary mast module and can be lowered at least to a level of that respective auxiliary mast module.
