Abstract
The invention provides a tower construction e.g. for a wind mill and a method of laying a foundation of a tower construction. The tower construction (1) comprises a concrete element (2), and a base flange (3) from which a tower wall (4) extends upwardly. The base flange is supported by an intermediate support structure (5) positioned on the concrete element (2). The support structure (5) is more rigid than the concrete element (2) and comprises a resilient pressure distributing element (6) which is soft relative to the concrete element (2). Furthermore, the invention provides a support structure for a tower construction.
Claims15
A tower construction comprising:
- a concrete element;
- a base flange comprising a lower surface and an opposite upper surface from which a tower wall extends upwardly, the base flange being supported by an intermediate support structure positioned on the concrete element, the support structure being more rigid than the concrete element;
- and
- a second casting layer located between the concrete element and the base flange, the second casting layer being provided to distribute a pressure on the support structure to the concrete element;
- the support structure comprising a resilient pressure distributing element and a levelling structure being located between the lower surface and the pressure distributing element, the resilient pressure distribution element being soft relative to the concrete element and the levelling structure being provided to level the base flange relative to the concrete element,
- wherein the rigidity of the combination of the resilient pressure distributing element and the levelling structure is in the range of the rigidity of the second casting layer.
A method of laying a foundation of a tower construction which comprises a base flange with a lower surface and an opposite upper surface, from which a tower wall extends upwardly, the method comprising the steps of:
- casting a concrete element;
- providing an intermediate support structure being more rigid than the concrete element, the support structure comprising a resilient pressure distributing element and a levelling structure, the resilient pressure distributing element being soft relative to the concrete element;
- arranging the support structure on an upper mounting plane of the concrete element;
- lowering the base flange onto the support structure;
- levelling the base flange relative to the concrete element;
- arranging a second casting layer between the concrete element and the base flange, the rigidity of the combination of the resilient pressure distributing element and the levelling structure being in the range of the rigidity of the second casting layer;
- and
- fixating the base flange to the concrete element.
