Tower for a Wind Power Installation

Abstract

The invention relates to a tower for a wind power installation, wherein the walls of the tower are at least partially produced from individual wall sections which are connected to one another by means of connection means. The object of the invention is therefore to provide a tower which can be assembled with a sufficient degree of precision. It is also the object of the invention to provide a method for erecting a tower of this kind. The object according to the invention in respect of a tower of this kind is achieved in that an empty framework is at least partially provided in the interior of the tower and the wall sections are retentively connected to said empty framework.

         35 . The tower as claimed in  claim 1 , characterized in that the wall sections at least partially in joints have slots which are arranged transversely to the direction of the joint or longitudinally to the direction of the joint. 
     
     
         36 . The tower as claimed in  claim 35 , characterized in that the connection means, in a preferred manner metal plates, in a particularly preferred manner perforated plates, are arranged in the slots and are preferably bonded in the slots. 
     
     
         37 . The tower as claimed in  claim 1 , characterized in that the individual wall sections are produced from as wood material wherein in a preferred manner the wood material is laminated plywood or a wood composite material. 
     
     
         38 . The tower as claimed in  claim 1 , characterized in that the tower is assembled on site from the individual wall sections. 
     
     
         39 . The tower as claimed in  claim 1 , characterized in that the surface of the exterior of the tower is provided with a coating. 
     
     
         40 . The tower as claimed in  claim 39 , characterized in that the coating absorbs at least part of the tensile stress acting on the surface of the tower and seals the surface of the exterior of the tower against the environmental influences, in particular moisture, which act on the surface from the outside. 
     
     
         41 . The tower as claimed in  claim 39 , characterized in that the coating is applied onto the surface of the exterior of the tower at least partially over the entire area. 
     
     
         42 . The tower as claimed in  claim 39 , characterized in that the coating is a laminate, a foil, a woven fabric, a plate or a textile, wherein in as preferred manner the coating is a plastics material, a plastics material plate, a woven fabric or a textile made from a plastics material, which, in a preferred manner, are produced from poly propylene, polyurethane, polyvinyl chloride, polyester, polycarbonate or polythene. 
     
     
         43 . The tower as claimed in  claim 39 , characterized in that the coating is bonded at least partially onto the tower surface, wherein in a preferred manner, the coating consists of individual sections which are connected together, in a preferred manner bonded or welded together. 
     
     
         44 . The tower as claimed in  claim 43 , characterized in that the vapor permeability of the coating is less than that of the wood material. 
     
     
         45 . The tower as claimed in  claim 39 , characterized in that a heat generator is arranged in the interior of the tower, wherein, in a preferred manner, this is the power electronics of a wind power installation. 
     
     
         46 . The tower as claimed in  claim 39 , characterized in that the support structure of the tower is constructed at least partially from materials which are not suitable for exterior use.
