Description

Die Erfindung betrifft ein thermisch isolierendes Bauelement der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The invention relates to a thermally insulating component of the type specified in the preamble of claim 1.

Die EP 1 892 344 A1 beschreibt ein thermisch isolierendes Bauelement zum Einsatz in Trennfugen zwischen zwei in einer Längsrichtung aneinandergrenzenden Bauwerksteilen, insbesondere einer Gebäudedecke und einer Balkonplatte. Das Bauelement umfasst zwei übereinander befindliche etwa quaderförmige Isolierkörper mit darin angeordneten und quer zu deren Längsachse verlaufenden Zugankern sowie Druck- und Schublagern. Die Isolierkörper sind jeweils durch einen Kasten gebildet, der mit einem Isoliermaterial, beispielsweise Steinwolle gefüllt ist.The EP 1 892 344 A1 describes a thermally insulating component for use in joints between two adjoining in a longitudinal direction structural parts, in particular a building ceiling and a balcony slab. The component comprises two superimposed approximately cuboid insulating body arranged therein and extending transversely to the longitudinal axis of tie rods and pressure and thrust bearings. The insulating bodies are each formed by a box which is filled with an insulating material, for example rock wool.

Die EP 2 138 641 A2 beschreibt ein Bauelement zur Wärmedämmung zwischen zwei Bauteilen, insbesondere zwischen einem Gebäude und einem vorkragenden Außenteil. Das Bauelement besteht aus einem zwischen den Bauteilen zu verlegenden Isolierkörper mit zumindest integrierten Druckelementen, die im eingebauten Zustand des Bauelementes im Wesentlichen horizontal und quer zur im Wesentlichen horizontalen Längserstreckung des Isolierkörpers durch diesen hindurch verlaufen und jeweils an beide Bauteile anschließbar sind. Der Isolierkörper ist von Zugkraftbewehrungselementen durchsetzt. Weiter ist ein Druckkraftbewehrungselement vorgesehen, das stirnseitige, treppenstufenförmige Vorsprünge aufweist, die in die angrenzenden Betonbauteile vorstehen.The EP 2 138 641 A2 describes a component for thermal insulation between two components, in particular between a building and a projecting outer part. The component consists of an insulator to be laid between the components with at least integrated pressure elements which extend in the installed state of the component substantially horizontally and transversely to the substantially horizontal longitudinal extent of the insulating body therethrough and are connectable to both components. The insulating body is penetrated by tensile reinforcement elements. Further, a Druckkraftbewehrungselement is provided which has frontal, stair-step-shaped projections which protrude into the adjacent concrete components.

Der Erfindung liegt die Aufgabe zugrunde, ein thermisch isolierendes Bauelement der gattungsgemäßen Art zu schaffen, das in einem Bereich nahe zumindest einer Oberfläche eines angrenzenden Bauwerkteils eine verbesserte Verbindung des Bauelementes mit dem Bauwerksteil ermöglicht.The invention has for its object to provide a thermally insulating component of the generic type, in an area near at least one surface an adjacent building part allows an improved connection of the component with the building part.

Diese Aufgabe wird erfindungsgemäß durch ein thermisch isolierendes Bauelement mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a thermally insulating component with the features of claim 1.

Durch die erfindungsgemäße Anordnung und entsprechende Ausrichtung der Leisten wird über die Länge des Bauelementes ein zusätzlicher Formschluss des Betons beim Gießen des angrenzenden Bauwerkteils erreicht, so dass insbesondere im Bereich nahe der Oberflächen der angrenzenden Bauwerksteile eine verbesserte Verankerung gegeben ist.As a result of the arrangement according to the invention and the corresponding alignment of the strips, an additional positive connection of the concrete during casting of the adjacent structural part is achieved over the length of the structural element, so that an improved anchoring is provided, in particular in the region near the surfaces of the adjacent structural parts.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass der erste Kasten an der dem zweiten Kasten abgewandten Seite bezogen auf den Querschnitt des Kastens einen verbreiterten Abschnitt aufweist, der durch sich entlang beider Seitenwände des Kastens erstreckende Ausformungen gebildet ist und an einem äußeren Rand der Ausformungen Leisten angeordnet sind, die sich in einem Abstand parallel zu Seitenwänden des ersten Kastens erstrecken. Auf diese Weise wird sowohl an der Oberseite als auch an der Unterseite des Bauwerksteils der zusätzliche Formschluss erreicht.According to a preferred embodiment of the invention it is provided that the first box on the side facing away from the second box relative to the cross section of the box has a widened portion which is formed by extending along both side walls of the box moldings and at an outer edge of the formations Bars are arranged, which extend at a distance parallel to side walls of the first box. In this way, the additional positive locking is achieved both at the top and at the bottom of the building part.

Eine vorteilhafte Ausgestaltung besteht darin, dass der zumindest eine Kasten aus einem Kunststoffmaterial besteht und die Leisten an den äußeren Rändern angeformt sind. Auf diese Weise können die Leisten gleichzeitig mit dem Kastenprofil beim Extrudieren hergestellt werden. Als zweckmäßige Form des verbreiterten Abschnitts der Kästen wird angesehen, dass sich der verbreiterte Abschnitt neben einer äußeren Wand des zumindest einen Kastens befindet und die Ausformungen durch einen geneigt zur äußeren Wand verlaufenden Wandabschnitt und einem rechtwinklig zur Seitenwand verlaufenden Wandabschnitt gebildet sind.An advantageous embodiment is that the at least one box is made of a plastic material and the strips are integrally formed on the outer edges. In this way, the strips can be produced simultaneously with the box profile during extrusion. As an expedient form of the widened portion of the boxes, it is considered that the widened portion is adjacent to an outer wall of the at least one box and the formations are formed by a wall portion sloping towards the outer wall and a wall portion extending at right angles to the side wall.

Vorzugsweise weist die Leiste eine Höhe von 1 mm bis 10 mm und eine Dicke von mindestens 1mm auf. Der Abstand zwischen der Längsseitenwand und der Leiste beträgt vorzugsweise etwa 9 mm. In weiterer Ausgestaltung des thermisch isolierenden Bauelementes ist es vorteilhaft, dass zwischen dem ersten Kasten und dem zweiten Kasten ein weiterer Kasten angeordnet ist. Durch dieses Baukastenprinzip lassen sich Bauelemente mit unterschiedlichen Bauhöhen zusammenstellen, je nach Bedarf.Preferably, the strip has a height of 1 mm to 10 mm and a thickness of at least 1 mm. The distance between the longitudinal side wall and the strip is preferably about 9 mm. In a further embodiment of the thermally insulating component It is advantageous that between the first box and the second box another box is arranged. Due to this modular principle, components with different heights can be assembled as needed.

Die Kästen 2, 3 bilden gemeinsam einen Isolierkörper 6 (vgl. Fig. 2). Die Bewehrungsstäbe 4 erstrecken sich orthogonal zur Längsachse des ersten Kastens 2 durch diesen hindurch. Die Lager 5 sind im zweiten Kasten 3 so angeordnet, dass sie mit ihren Schmalseiten aus den Seitenwänden dieses zweiten Kastens 3 hervorstehen, um sich an dem jeweils angrenzenden Bauwerksteil abzustützen (vgl. Fig. 2).In Fig. 1 a thermally insulating component 1 is shown, which consists of two superimposed elongated boxes 2, 3 and reinforcing bars 4 for the tensile reinforcement and bearings 5 for receiving pressure and shear forces.

Die Fig. 4 zeigt eine Ausführungsvariante zu Fig. 1 mit einem Bauelement 25, bei dem ein Isolierkörper 26 (vgl. Fig. 5) aus einem zwischen einem ersten Kasten 32 und einem zweiten Kasten 33 angeordneten dritten Kasten 30 besteht. Der erste Kasten 32 hat eine geringere Bauhöhe als der erste Kasten 2 in Fig. 1. Durch dieses Baukastenprinzip lassen sich Bauelemente 1, 25 mit unterschiedlichen Bauhöhen zusammenstellen, je nach Bedarf. Die Bezugszeichen für gleiche Teile stimmen mit denjenigen der Fig. 1 überein. Der erste Kasten 32 ist mit Leisten versehen, von denen in dieser Perspektive lediglich eine Leiste 24 erkennbar ist. Das Gleiche gilt für den zweiten Kasten 33 an dem lediglich eine Leiste 48 zu sehen ist. Wird der erste Kasten 32, der eine gegenüber dem ersten Kasten 2 in Fig. 1 geringere Höhe aufweist, mit dem zweiten Kasten 33 ohne Zwischenschaltung des dritten Kastens 30 verbunden, so ergibt sich ein Bauelement von geringerer Höhe, so dass je nach gewünschter Höhe unterschiedliche Kombinationen möglich sind.The Fig. 4 shows an alternative embodiment Fig. 1 with a component 25 in which an insulating body 26 (cf. Fig. 5 ) consists of a arranged between a first box 32 and a second box 33 third box 30. The first box 32 has a lower height than the first box 2 in Fig. 1 , By this modular principle, components 1, 25 can assemble with different heights, as needed. The reference numerals for the same parts agree with those of Fig. 1 match. The first Box 32 is provided with strips, of which in this perspective only a bar 24 can be seen. The same applies to the second box 33 on which only one bar 48 can be seen. Is the first box 32, one opposite the first box 2 in Fig. 1 has lower height, connected to the second box 33 without the interposition of the third box 30, the result is a component of lesser height, so that different combinations are possible depending on the desired height.

Die Fig. 5 zeigt eine Ansicht auf die Längsseite des Bauelementes 25 gemäß Fig. 4, allerdings im montierten Zustand. Der Isolierkörper 26 des Bauelements 25 wird aus den Kästen 30, 32, 33 gebildet, die übereinander gestapelt und fest miteinander verbunden sind. Die drei Kästen 30, 32, 33 bestehen vorzugsweise aus demselben Material. Aus dieser Ansicht sind eine äußere Wand 28 am ersten Kasten 32 und eine äußere Wand 29 am zweiten Kasten 33 zu sehen und außerdem Ausformungen 27 und 31, an denen jeweils Leisten 24, 48 angeordnet sind. Die im regelmäßigen Abstand angeordneten Bewehrungsstäbe 4 sind ersichtlich und ebenso die Lager 5.The Fig. 5 shows a view on the longitudinal side of the device 25 according to Fig. 4 , but in assembled condition. The insulating body 26 of the device 25 is formed from the boxes 30, 32, 33, which are stacked one above the other and firmly connected. The three boxes 30, 32, 33 are preferably made of the same material. From this view, an outer wall 28 on the first box 32 and an outer wall 29 on the second box 33 can be seen and also formations 27 and 31, on each of bars 24, 48 are arranged. The regularly spaced reinforcing bars 4 are visible and also the bearings. 5
