Abstract
Description
Die Erfindung betrifft ein vorgefertigtes Bauelement mit zwei durch Verbindungsstücke zueinander im Abstand gehaltenen Schalen und einer gegen eine Betonoberfläche einer der Schalen anliegenden, mit dieser Schale verbundenen Dämmung.The invention relates to a prefabricated component with two mutually spaced by connecting pieces spaced shells and a voltage applied to a concrete surface of one of the shells, associated with this shell insulation.
Ein solches Bauelement mit zwei Schalen und einer innenliegenden Dämmung ist aus der
Mit zunehmender Festigkeit der Dämmung kommt es durch die flächenhafte Anhaftung der Dämmung an den Beton der Betonschale infolge unterschiedlicher Wärmedehnungen von Dämmung und Betonschale zu Beeinträchtigungen sowohl des Betons als auch der Dämmung, insbesondere zu Rissen.With increasing strength of the insulation, the areal adhesion of the insulation to the concrete of the concrete shell as a result of different thermal expansions of insulation and concrete shell leads to impairments of both the concrete and the insulation, in particular to cracks.
Der Erfindung liegt die Aufgabe zugrunde, ein neues Bauelement der eingangs erwähnten Art mit verminderter Empfindlichkeit gegen Wärmeeinwirkungen und Spannungen zu schaffen.The invention has for its object to provide a new device of the type mentioned above with reduced sensitivity to heat and stress.
Das diese Aufgabe lösende Bauelement nach der Erfindung ist dadurch gekennzeichnet, dass die Dämmung mit der Schale durch von der Dämmung in den Beton der Betonoberfläche hinein vorstehende Verbindungselemente oder/und an die Verbindungsstücke gekoppelte Halteelemente verbunden und eine Anhaftung der Dämmung an der Schale beim Abbinden des Betons durch die Beschaffenheit der der Betonoberfläche der Schale zugewandten Oberfläche der Dämmung vermieden oder zumindest reduziert ist.The problem solving device according to the invention is characterized in that the insulation connected to the shell by from the insulation in the concrete concrete surface protruding into connecting elements and / or coupled to the connecting elements holding elements and an adhesion of the insulation to the shell during setting of Concrete is avoided or at least reduced by the nature of the concrete surface of the shell facing surface of the insulation.
Gemäß der Erfindung erfolgt die Verbindung der Dämmung mit der Schale durch Verbindungselemente unter Meidung einer flächenhaften, Eigenspannungen hervorrufenden Anbindung der Dämmung an den Schalenbeton. Die Bildung von Rissen in der Dämmung durch solche Spannungen ist mit sehr lauten, insbesondere im Wohnungsbau völlig unakzeptablen Knallgeräuschen verbunden.According to the invention, the connection of the insulation with the shell by means of connecting elements under the avoidance of a two-dimensional, intrinsic stresses causing connection of the insulation to the shell concrete. The formation of cracks in the insulation by such voltages is associated with very loud, especially in housing totally unacceptable blast noise.
In einer bevorzugten Ausführungsform der Erfindung ist die Haltekraft zwischen der Schale und der Dämmung infolge Anhaftung, zumindest in zur Schalenebene paralleler Richtung, kleiner als die durch die Verbindungs- bzw. Halteelemente erzeugte, der Steifigkeit der Verbindungs- bzw. Halteelemente beruhenden Haltekraft.In a preferred embodiment of the invention, the holding force between the shell and the insulation due to adhesion, at least in the plane parallel to the shell plane, smaller than that produced by the connecting or holding elements, the rigidity of the connecting or holding elements based holding force.
Vorzugsweise beträgt die Haltekraft infolge Anhaftung höchstens 50%, vorzugsweise 25% und insbesondere höchstens 10% der durch die Verbindungselemente erzeugten Haltekraft.Preferably, the holding force due to adhesion is at most 50%, preferably 25% and in particular at most 10% of the holding force generated by the connecting elements.
Während es möglich ist, durch die Materialwahl der Dämmung eine nicht anhaftende Oberfläche zu erzeugen, ist die betreffende Oberfläche in einer besonders bevorzugten Ausführungsform der Erfindung durch eine der Anhaftung entgegenwirkende Beschichtung gebildet.While it is possible to create a non-adherent surface by the choice of material of the insulation, the surface in question is formed in a particularly preferred embodiment of the invention by a coating counteracting the adhesion.
Insbesondere weist diese Beschichtung ein gegen chemische Reaktionen mit dem abbindenden Beton resistentes Material auf, insbesondere ein Kunststoffmaterial.In particular, this coating has a material resistant to chemical reactions with the setting concrete, in particular a plastic material.
Die Beschichtung kann auf einer Kaschierung der Dämmung, insbesondere der häufig für Dämmplatten verwendeten Aluminiumkaschierung, gebildet sein. So verhindert die Beschichtung Reaktionen der Kaschierung mit dem abbindenden Beton.The coating may be formed on a lamination of the insulation, in particular the aluminum lamination often used for insulation boards. Thus, the coating prevents reactions of the lamination with the setting concrete.
In weiterer vorteilhafter Ausgestaltung der Verbindung sind die Verbindungselemente Bolzenelemente, die vorzugsweise aus einem Kunststoff bestehen.In a further advantageous embodiment of the compound, the connecting elements are bolt elements, which preferably consist of a plastic.
Zweckmäßig weisen die Verbindungselemente einen die Dämmung hintergreifenden Kopf auf, so dass die Dämmung formschlüssig an der betreffenden Schale gehalten ist.Suitably, the connecting elements have a head engaging behind the insulation, so that the insulation is held in a form-fitting manner on the relevant shell.
In einer Ausführungsform der Erfindung ist der Kopf innerhalb der Dämmung im Abstand zu deren der Betonoberfläche abgewandten Oberfläche angeordnet. Vorteilhaft wirkt diese Maßnahme infolge verringerter Einspannwirkung der Bildung die Dämmung durchsetzender Risse entgegen.In one embodiment of the invention, the head is disposed within the insulation at a distance from the surface facing away from the concrete surface. Advantageously, this measure counteracts the insulation penetrating cracks due to reduced clamping action of education.
