Description

Die vorliegende Erfindung betrifft ein Bauelement zur Wärmedämmung zwischen zwei zu betonierenden Bauteilen, insbesondere zwischen einem Gebäude und einem vorkragenden Außenteil mit den Merkmalen des Oberbegriffs von Anspruch 1.The present invention relates to a component for thermal insulation between two components to be concreted, in particular between a building and a projecting outer part with the features of the preamble of claim 1.

Derartige Bauelemente werden beispielsweise zwischen einem Balkon und der zugehörigen Geschossdecke eingebaut, um eine Kältebrücke in diesem Bereich weitestgehend zu vermeiden, wobei Bewehrungsstäbe, die an beide Bauteile, also an den Balkon und an die Geschossdecke, unter Durchquerung des Isolierkörpers angeschlossen sind, für die nötige Übertragung der auftretenden Zug-, Quer- und Druckkräfte sorgen. Im Regelfall - wie er z. B. in der EP-A 0 831 183 offenbart ist - bestehen diese Bewehrungselemente im Fugenbereich aus Edelstahl, der ausreichenden Schutz vor Korrosion bietet und auf der anderen Seite auch gute Wärmedämmeigenschaften besitzt. Nachteilig an den Edelstahl-Bewehrungsstäben sind aber insbesondere die hohen Kosten, vor allem wenn - wie es bei den Druckelementen der Fall ist - zur Erzielung einer ausreichenden Tragfähigkeit Bewehrungselemente mit relativ großen Querschnitten verwendet werden müssen.Such components are installed, for example, between a balcony and the associated floor ceiling to avoid a cold bridge in this area as far as possible, with reinforcing bars, which are connected to both components, ie to the balcony and the floor slab, traversing the insulator, for the necessary Transmission of the occurring tensile, transverse and compressive forces provide. As a rule - as he z. B. in the EP-A 0 831 183 discloses - consist of these reinforcing elements in the joint area of stainless steel, which provides adequate protection against corrosion and on the other hand also has good thermal insulation properties. However, a disadvantage of the stainless steel reinforcing bars is in particular the high costs, especially if - as is the case with the printing elements - reinforcing elements with relatively large cross sections have to be used in order to achieve adequate load-bearing capacity.

Im Stand der Technik sind zwar bereits Lösungsansätze (s. z.B. EP-A 0 121 685 ) dafür bekannt, wie man den Einsatz von Edelstahl-Druckelementen umgeht und statt dessen alternative Materialien verwendet: So schlägt beispielsweise die DE 34 26 538 vor, die Druckelemente aus Ortbeton herzustellen, wobei sich diese Betondruckelemente sowohl durch einen günstigen Preis als auch durch ausreichend günstige Korrosionsbeständigkeit auszeichnen. Nachteilig an - auch aus DE-A 31 16 381 bekannten - Betondruckelementen ist jedoch die vergleichsweise schlechte Wärmedämmeigenschaft von Beton, die ja gerade durch die Verwendung des Bauelements zur Wärmedämmung im Fugenbereich umgangen werden sollte.In the prior art, although already solution approaches (szB EP-A 0 121 685 ) for how to avoid the use of stainless steel printing elements and instead uses alternative materials: For example, proposes the DE 34 26 538 Prior to producing the pressure elements of in-situ concrete, these concrete pressure elements are characterized both by a low price and by sufficiently favorable corrosion resistance distinguished. Disadvantageous - even out DE-A 31 16 381 However, known - concrete pressure elements is the relatively poor thermal insulation property of concrete, which should be bypassed just by the use of the device for thermal insulation in the joint area.

Hiervon ausgehend liegt nun der vorliegenden Erfindung die Aufgabe zugrunde, ein Bauelement zur Wärmedämmung der eingangs genannten Art zur Verfügung zu stellen, dessen Druckelemente sich durch gute Wärmedämmeigenschaften, eine gute Korrosionsbeständigkeit und durch günstige Kosten auszeichnen.Proceeding from this, the present invention has the object to provide a device for thermal insulation of the type mentioned above, the pressure elements are characterized by good thermal insulation properties, good corrosion resistance and low cost.

Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Anspruchs 1.This object is achieved by the features of claim 1.

Hierdurch ergibt sich der Vorteil eines Druckelementes, das nicht nur kostengünstiger als Edelstahl-Druckelemente ist, sondern bei größerer Tragfähigkeit auch eine bessere Wärmedämmung aufweist. Wenn in besonders vorteilhafter Weise das Druckelement durch Extrusion hergestellt wird, lassen sich in einfacher Weise Hohlräume in das Beton-Druckelement einbringen, die erst für die gegenüber Edelstahl verbesserte Wärmedämmung sorgen. Mit anderen Worten ermöglicht das Extrusionsverfahren ein Druckelement in Leichtbauweise mit schlanken und dennoch tragfähigen Druckstegen und mit einem zwischen den Druckstegen eingeschlossenen Isolierelement, das in einfachster Weise aus Luft besteht und damit beste Dämmeigenschaften besitzt.This results in the advantage of a pressure element that is not only less expensive than stainless steel pressure elements, but also has better thermal insulation at greater load capacity. If the pressure element is produced by extrusion in a particularly advantageous manner, cavities can be introduced into the concrete pressure element in a simple manner, which only provide for the improved thermal insulation compared to stainless steel. In other words, the extrusion process allows a pressure element in lightweight construction with slim yet sustainable pressure bars and with a trapped between the pressure bars insulating, which consists of air in the simplest way and thus has the best insulating properties.

Die Leichtbauweise wird dadurch begünstigt, dass die Druckelemente an ihren den Betonbauteilen zugewandten Stirnseiten Kontaktprofile zur Druckkrafteinleitung bzw. Druckkraftausleitung aufweisen. Diese Kontaktprofile erstrecken sich zweckmäßigerweise parallel zur Längserstreckung des Isolierkörpers und sind plattenförmig ausgebildet mit einer den Betonbauteilen zugewandten vertikalen Fläche, die in ihrer Größe zumindest der von den Druckstegen umschlossenen Vertikalquerschnittsfläche entspricht. Mit anderen Worten sollen die Kontaktprofile eine großflächige Druckkrafteinleitung bzw. -ausleitung ermöglichen und hierbei die Druckkraft an die demgegenüber kleinere Querschnittsfläche der Druckstege weitergeben. Damit die Druckstege der Druckkraft besser Stand halten, verbinden die Kontaktprofile die zumindest zwei Druckstege zu einem Profilkörper, so dass die Kontaktprofile den Druckstegen weitere Stabilität verleihen können.The lightweight construction is facilitated by the fact that the pressure elements have contact profiles for the introduction of pressure force or pressure force discharge at their end faces facing the concrete components. These contact profiles extend expediently parallel to the longitudinal extension of the insulating body and are plate-shaped with a concrete components facing vertical surface which corresponds in size at least the area enclosed by the pressure webs vertical cross-sectional area. In other words, the contact profiles are to enable a large-scale introduction of pressure or -ausleitung and this the compressive force to the contrast smaller cross-sectional area of the Pass on pressure bridges. In order for the pressure ridges to better withstand the compressive force, the contact profiles connect the at least two pressure ridges to form a profile body, so that the contact profiles can give the pressure ridges further stability.

Darüber hinaus kann es herstellungsbedingt von Vorteil sein, wenn die Druckstege über eine den Hohlraum durchquerende Querstrebe miteinander verbunden sind, die das Einknicken des nach dem Extrusionsvorgang noch nicht ausgehärteten Druckelements im Bereich der schlanken Druckstege verhindert. So wie sich die Querstrebe problemlos durch das erfindungsgemäße Extrusionsverfahren in die Druckelemente einbringen lässt, können ohne größeren Aufwand zusätzliche die Stabilität einerseits und die Wärmedämmung andererseits begünstigende konstruktive Maßnahmen getroffen werden, was bei den üblichen Edelstahldrucklagern kaum bzw. mit nur unverhältnismäßig hohem Aufwand möglich wäre.In addition, it can be production-related advantage if the pressure bridges are connected to one another via a transverse strut crossing the cavity, which prevents the buckling of the pressure element not yet cured after the extrusion process in the region of the slender pressure webs. Just as the crossbar can be easily introduced by the extrusion process according to the invention in the printing elements, additional stability on the one hand and the thermal insulation on the other hand favoring constructive measures can be taken without much effort, which would be possible in the usual stainless steel pressure bearings hardly or only with disproportionately high effort.

Was die Extrusionsrichtung bei dem erfindungsgemäßen Druckelement betrifft, so empfiehlt es sich, dass der Hohlraum durch die Kontaktprofile gegenüber dem Betonbauteilen abgeschirmt ist, also das Druckelement so herzustellen, dass sich die Hohlraumachse und damit die Extrusionsrichtung in der Ebene des Isolierkörpers horizontal in Richtung der Längserstreckung des Isolierkörpers oder senkrecht hierzu in Vertikalrichtung erstreckt.As for the extrusion direction in the pressure element according to the invention, it is recommended that the cavity is shielded by the contact profiles relative to the concrete components, so the pressure element to produce so that the cavity axis and thus the extrusion direction in the plane of the insulating horizontally in the direction of the longitudinal extent of the insulating body or extending perpendicular thereto in the vertical direction.

Zur Vergrößerung des Hohlraums empfiehlt es sich darüber hinaus, dass die Druckelemente zumindest in eines der beiden Betonbauteile vorstehen und in diesem Betonbauteil verankert sind, insbesondere dass sich der Hohlraum auf der in das Betonbauteil vorstehenden Seite des Druckelementes etwa bis zum Betonbauteil erstrecken kann und nur noch durch das zugehörige Kontaktprofil gegenüber diesem Betonbauteil abgeschirmt ist. Hierdurch vergrößert sich darüber hinaus die Länge der Druckstege und damit des dünnwandigen Druckelementbereichs und somit verbessert sich auch die Wärmedämmung.To increase the cavity, it is also recommended that the pressure elements protrude at least in one of the two concrete components and anchored in this concrete component, in particular that the cavity on the projecting into the concrete component side of the pressure element may extend to the concrete component and only is shielded by the associated contact profile with respect to this concrete component. This also increases the length of the pressure ribs and thus of the thin-walled pressure element area and thus also improves the thermal insulation.

In Figur 2 ist ein Bauelement 1 zur Wärmedämmung auszugsweise dargestellt, das zwischen einem Gebäude A und einem vorkragenden Außenteil B eingebaut ist und aus einem zwischen den beiden Bauteilen verlegten Isolierkörper 2 und Bewehrungselementen in Form eines Druckelementes 3 besteht. Im allgemeinen ist das Bauelement nach oben verlängert und trägt dort Zugstäbe und Querkraftstäbe wie an sich bekannt.In FIG. 2 is a component 1 for thermal insulation extracts shown, which is installed between a building A and a cantilevered outer part B and consists of a laid between the two components insulating body 2 and reinforcing elements in the form of a pressure element 3. In general, the device is extended upward and there carries tension rods and transverse force rods as known per se.

Das Druckelement 3 weist zwei plattenförmige Kontaktprofile 5, 6 auf, die an den den beiden Betonbauteilen A und B zugewandten Stirnseiten des Druckelements 3 angeordnet sind und parallel zu der Längserstreckung des Isolierkörpers verlaufen. Die Kontaktprofile 5, 6 dienen zur Ein- bzw. Ausleitung der Druckkraft, wobei die Druckkraftübertragung durch die Fuge zwischen den beiden Bauteilen durch zwei Druckstege 7, 8 zur Verfügung gestellt wird, die demgemäss quer zur Längserstreckung des Isolierkörpers durch diesen hindurchverlaufen.The pressure element 3 has two plate-shaped contact profiles 5, 6, which are arranged on the two concrete components A and B facing end faces of the pressure element 3 and extend parallel to the longitudinal extent of the insulating body. The contact profiles 5, 6 are used for input and output of the pressure force, wherein the pressure force transmission through the joint between the two components by two pressure webs 7, 8 is provided, which accordingly run transversely through the longitudinal extent of the insulating body through this.

Die beiden Druckstege 7, 8 schließen zwischen sich einen Hohlraum 9 ein, der als Isolierelement fungiert und hierzu lediglich mit Luft gefüllt sein muss.The two pressure webs 7, 8 enclose between them a cavity 9, which acts as an insulating element and for this purpose only has to be filled with air.

Dadurch dass das Druckelement 3 in das Betonbauteil B im Bereich des Kontaktprofils 6 vorsteht, lässt sich das Hohlraumvolumen bzw. die Länge der Druckstege vergrößern und damit die durch das erfindungsgemäße Druckelement zur Verfügung gestellte Wärmedämmung weiter optimieren.Because the pressure element 3 projects into the concrete component B in the region of the contact profile 6, the void volume or the length of the pressure webs can be increased, thus further optimizing the thermal insulation provided by the pressure element according to the invention.

In den Figuren 3 und 4 ist ein Bauelement 21 zur Wärmedämmung dargestellt, dessen Druckelement 23 sich vom Druckelement 3 durch die Form des Extrusionsquerschnitts und durch die Einbauorientierung unterscheidet. Wie auch das Druckelement 3 weist das Druckelement 23 zwei an den den Betonbauteilen A, B zugewandten Stirnseiten vorgesehene Kontaktprofile 25, 26 auf und zwei sich zwischen den beiden Kontaktprofilen erstreckende Druckstege 27, 28.In the FIGS. 3 and 4 a component 21 is shown for thermal insulation, the pressure element 23 differs from the pressure element 3 by the shape of the extrusion cross-section and by the installation orientation. Like the pressure element 3, the pressure element 23 has two on the concrete components A, B facing end faces provided contact profiles 25, 26 and two extending between the two contact profiles pressure ridges 27, 28th

Die wesentlichen Unterschiede liegen demgegenüber darin, dass die Kontaktprofile 25, 26 nicht plattenähnlich parallel zur Längserstreckung des Isolierkörpers angeordnet sind, sondern statt dessen gewölbt ausgebildet sind mit einer auf den Horizontalschnitt bezogenen etwa kreisbogenförmigen Außenform. Um das Ausknicken der Druckstege im Bereich des Hohlraums 29 zu verhindern, ist eine die beiden Druckstege verbindende Querstrebe 30 vorgesehen, die den Hohlraum 29 durchquert und in zwei Hohlraumhälften 29a, 29b teilt. Darüber hinaus sind die Druckstege 27, 28 mit konkav gekrümmten Außenseiten versehen und die Hohlräume 29a, 29b sind im Gegensatz dazu konvex gewölbt. Hierdurch weisen die beiden Druckstege im Horizontalschnitt ungefähr eine Kelchform auf, die eine optimale Druckkraftübertragung bei minimalen Querschnittsflächen und somit optimaler Wärmedämmung ermöglicht.The essential differences are in contrast to the fact that the contact profiles 25, 26 are not arranged plate-like parallel to the longitudinal extent of the insulating body, but instead are curved with a related to the horizontal section approximately circular arc-shaped outer shape. In order to prevent the buckling of the pressure ribs in the region of the cavity 29, a cross strut 30 connecting the two pressure webs is provided, which traverses the cavity 29 and divides it into two cavity halves 29a, 29b. In addition, the pressure ribs 27, 28 are provided with concavely curved outer sides and the cavities 29a, 29b are in contrast convexly curved. In this way, the two pressure bridges in horizontal section approximately on a cup shape, which allows optimal pressure force transmission with minimal cross-sectional areas and thus optimum thermal insulation.

Die gewölbte Außenform der Kontaktprofile 25, 26 hat aufgrund ihres konvexen Verlaufs den Effekt, dass das Druckelement wie ein Gelenk etwaigen temperaturbedingten Relativbewegungen zwischen den beiden Betonbauteilen durch Drehung bzw. durch Abwälzen in der horizontalen Ebene folgen kann.The convex outer shape of the contact profiles 25, 26 has the effect due to its convex profile that the pressure element can follow any temperature-related relative movements between the two concrete components by rotation or by rolling in the horizontal plane as a joint.

Das Druckelement weist kreisbogenförmig ausgebildeten Kontaktprofile auf und eine kontinuierlich und absatzlos von den Rändern der Kontaktprofile übergehende kelchartige Außenform, die sich zur Fugenmitte langsam verjüngt und anschließend auf dem Weg zum gegenüberliegenden Kontaktprofil wieder kontinuierlich verbreitert, um dort absatzlos in die Ränder des gegenüberliegenden Kontaktprofils überzugehen. Diese Form gewährleistet eine optimale Krafteinleitung von der Balkonplatte B in das Druckelement, eine optimale Druckkraftübertragung bei reduzierter Wärmeleitung durch die Fuge und eine optimale Druckkraftausleitung in das Gebäude A. Die Querschnitte sind hierbei so gestaltet, dass sie bei möglichst großer Krafteinleitungsfläche und möglichst schlanker Druckkraftübertragungsquerschnittsfläche bei gegenseitigem kontinuierlichem Übergang ein dennoch knickfestes, stabiles Druckelement mit - aufgrund der geringen Querschnittsfläche - dennoch günstiger Wärmedämmung ergeben, insbesondere wenn als Material für das Druckelement Beton verwendet wird.The pressure element has circular arc-shaped contact profiles and a continuously and without offset from the edges of the contact profiles passing gob-like outer shape, which tapers slowly to the center of the joint and then continuously widened again on the way to the opposite contact profile to there without overflow into the edges of the opposite contact profile. This shape ensures optimum introduction of force from the balcony plate B in the pressure element, optimum pressure force transmission with reduced heat conduction through the joint and an optimal pressure force discharge into the building A. The cross sections are designed so that they with the largest possible force introduction surface and slender Druckkraftübertragungsquerschnittsfläche mutual continuous transition yet kink-resistant, stable pressure element with - due to the small cross-sectional area - still give better thermal insulation, especially when used as a material for the pressure element concrete.

Zusammenfassend bietet die vorliegende Erfindung den Vorteil eines optimierten Druckelementes, das sich aufgrund der Herstellung durch Extrusion einfach mit Hohlräumen versehen und somit in Leichtbauweise herstellen lässt. Als Ergebnis erhält man ein Druckelement mit verbesserten Wärmedämmeigenschaften, besserer Tragfähigkeit und gleichzeitig günstigen Herstellungskosten.In summary, the present invention offers the advantage of an optimized printing element, which is easily provided with cavities due to the production by extrusion and thus can be produced in lightweight construction. The result is a printing element with improved thermal insulation properties, better load capacity and at the same time low production costs.
