Concrete construction of modular design

A concrete construction of modular form for a wind-energy installation, the construction comprising

• at least two upright precast concrete wall elements alongside one another and one above the other, with two narrow sides that after joining together of the precast concrete wall elements form
• a vertical joint therebetween,
• an upper side and a lower side that after joining together of the precast concrete wall elements include a horizontal joint therebetween,
• a front side and a rear side;
• a first support anchored in one of the narrow sides, the opposite narrow side having a recess or depression;
• a further support anchored in the recess in such a way that when the narrow sides of the two precast concrete wall elements are assembled with formation of the vertical joint the two supports are connectable by connecting means;
• and
• a reinforced elastomer bearing in a recess or depression of the lower side of the precast concrete wall elements and, when the concrete construction is assembled, supported on the upper side of the precast concrete wall element disposed thereunder to form the horizontal gap, the supports each consisting of a profile member having a flange on which anchoring elements projecting into the concrete for anchorage with the precast concrete wall elements are mounted and on which a web for connecting together two wall elements is mounted, the web of the profile member of the support extending at an angle to the flange of ≦90° and that the anchoring elements extend by the shank thereof substantially parallel to wall planes of the wall elements.
