Definitions
- the invention relates to a component for thermal insulation between two components to be concreted, in particular between a building and a cantilevered outer part, consisting of one to be installed in between Insulating body with at least integrated pressure elements, which in the installed state of the component essentially horizontally and transversely to the essentially horizontal longitudinal extent of the insulating body run through it and to both Components can be connected.
- Such printing plates in particular disc-shaped are formed and parallel to the longitudinal extension of the Insulator and perpendicular to that through the insulator extending pressure elements are arranged however, the disadvantage that the central axis the pressure elements not as deep as possible in the thermal insulation component can be arranged. Because for one can the height offset between the central axis of the Printing elements and printing plate underside not in larger Dimensions are reduced while maintaining the printing plate function and the other a certain concrete or. Insulation body thickness to be adhered to Pressure plate and thus the corrosion-prone pressure element protect against corrosion. This will, however prevents what is generally sought, namely the distance between tension and compression elements if possible large to choose, thereby the on the pressure element to be able to enlarge transmitted moment.
- Another component of the type mentioned is known from DE-U 93 18 354 and has printing elements Plastic material whose longer, effective cross-sectional axis is the vertical axis so it too be suitable for shear force absorption and also a certain one lateral movement or lateral movement in horizontal Direction and transverse to the longitudinal extent of this Allow items.
- Such printing elements have but precisely because of their vertical orientation the disadvantage of a smaller lever arm effective central axis of the pressure elements compared to the Tension rod axis, whereby that which can be transmitted through the pressure element Moment is correspondingly smaller.
- the pressure elements each have a plurality of vertically extending elements when the component is installed
- the printing elements of the stand dertechnik Vertical and horizontal extension in the The level of the joint usually does not differ as this are designed to be rotationally symmetrical Printing element of the present invention characterized in that there is only one orientation of the printing element within the Thermal insulation element that meets the requirements of the Pressure element met.
- the pressure element according to the invention is due to the vertical, parallel to each other running pressure bars in the vertical direction stiff and thus kink-resistant, but smooth in the horizontal direction trained, which makes it lateral temperature-related Changes in length of the projecting outer part not disabled in front of the building. At a installation of the pressure element incorrectly rotated by 90 ° could only be a fraction of the pressure forces record for a long time.
- the printing element for the requirements that for each of the different stress directions within the joint exist by directional adjustment the dimension of the pressure bars optimally designed. This leads to drastic material savings.
- the vertical direction of the webs says that the entire pressure element starting from one component horizontal and thus transverse to the longitudinal extent of the joint to the other component, but here the pressure bars within this horizontal pressure element are at least partially arranged vertically.
- the pressure bars are expediently by at least connected a connecting web running transversely to this, that in the direction of the longitudinal extent of the insulating body is either vertical or horizontal, a mutual fixation of the webs to each other causes and this to a profile body connects.
- the profile body consists of at least three pressure bars and is the length of the pressure elements at least three times their height, which means a good relationship for each printing element between the cross section or the pressure element height and the compressive strength or the recordable torque.
- the webs advantageously extend exactly in Vertical direction through the insulator to meet the requirement vertical stiffness and horizontal To ensure thrust softness.
- the pressure bars can also be theirs Recommend inclination from the vertical, in some areas Should not exceed 45 °.
- the pressure elements in parallel on the sides facing the concrete component extending to the longitudinal direction of the insulating body have plate-shaped contact profiles, which are expedient at the same time replace the connecting bridge can by connecting the pressure bars with each other.
- the contact profile surfaces are the serve to absorb the compressive forces, essentially so dimensioned as large as the one circumscribed by the pressure bars Cross-sectional area of the pressure element, so that at least the vertical extension of the pressure element through the Contact profiles is not increased. This allows the distance of the contact profile from the lower edge of the Minimize the insulating body and therefore due to the larger Lever arm between the push and pull elements that to be picked up Increase moment.
- the plate-shaped design the contact profile includes in particular rough, ribbed or generally provided with protrusions Surfaces that are in contact with the adjacent concrete components improve.
- the plate-shaped Contact profile flatter and therefore wider be there on its back at short intervals of the pressure bars running perpendicular to it is supported and secured against bending. Consequently, the contact profile must be the same Force absorption no vertical projection over the also have reduced pressure webs in height.
- the plate-shaped thrust bearing is not larger than the cross-sectional area circumscribed by the pressure bars have to be executed and still the storage area is larger than the cross-sectional area of the web is carried out in the insulating body, so that the thrust bearing their function of introducing the compressive forces into the Can guarantee pressure element.
- the contact profiles positively connected to the adjacent concrete components are what by individual, extending into the concrete Projections, a correspondingly executed Surface or by extending into the concrete component Contact profile can take place.
- This will the horizontal thrust movements between the two Transfer components directly to the pressure element, which according to the invention is carried out smoothly is. This allows relative movements between the concrete components and the pressure element, which leads to an overuse the thrust bearing surface up to its Destruction can be prevented.
- the contact profiles at least partially embedded in the insulating body are and only to a small extent in the concrete component protrude so as to maintain a sufficient distance of to comply with the reinforcement in the concrete component. This means that the positioning of the pressure elements not consider the position of the reinforcement elements be taken.
- Pressure elements and not just the contact profiles at least partially protrude beyond the insulating body and be anchored in the adjacent concrete component, so one Establish positive locking, in particular the transmission favored by horizontal movements.
- the pressure elements made in particular of alkali-resistant, fiber-reinforced Plastic, for example made of glass fiber reinforced Thermoplastics or thermosets, because of this less heat conduction through the insulating body results.
- a plastic pressure element is required no concrete or insulating material covering, since it is not sensitive to corrosion. Rather, the plastic pressure element can be flush with the adjoining concrete components are laid, which means that Manageability is improved.
- a simplification in the assembly of the component for thermal insulation and a reduction in processing costs results from the fact that the length of the Pressure element correspond to the length of the insulating body can and therefore only one pressure element per insulator with a correspondingly large number of pressure bars for Must be made available.
- the pressure elements can also be made in a modular design individual webs and / or contact profiles assembled be or individual printing elements to one composite pressure element variable in length be combined.
- combining can via a connecting bridge or via suitable connecting means especially by mutual gluing, Clip on or snap into place.
- a pressure element 1 is shown in plan view, that is between a building part A and a projecting outer part B, for example a concrete slab, extends.
- the pressure element 1 consists of eight vertical webs 2, at the end of each plate-shaped extending perpendicular to the pressure bars

- the contact profile 3 for the transmission of Pressure forces on the balcony slab B, while the contact profile 4 flat on the building component A connected.
- Any means of positive locking Anchoring the contact profiles in the concrete components - for example in the form of protrusions - are of simplicity not shown in the principle drawings.
- an insulating body 5 is also arranged in the joint between the building component A and the balcony slab B, which extends along the entire joint and has only recesses for the tensile, transverse force and pressure elements to be introduced.
- the insulating body also extends above the pressure element 1 in the joint in order to prevent sound and heat transmission through the joint. It can also be seen from the sectional view in FIG. 2 that the length of the pressure element 1 in the direction of the longitudinal extent of the insulating body is a multiple of its vertical height, namely twice in the present case.
- Figure 3 finally shows the pressure element 1 in side view and leaves the arrangement of the pressure element within recognize the joint between the two concrete components. It is particularly evident that the Pressure element in the lowest possible position within the joint can be installed, in particular the two plate-shaped contact profiles 3 and 4 not protrude downward from the pressure webs 2. In particular if the pressure element 1 is made of plastic it is not subject to corrosion, if it is flush with the underside of the component in the joint is arranged and thus exposed to the surrounding climate is.
- the contact profiles 3 and 4 are flush with the two concrete components A and B. However, they can also do the same anchored in the concrete components by means of projections be or be partially or wholly in this Extend concrete components flat.

Abstract
Description
Die Erfindung betrifft ein Bauelement zur Wärmedämmung zwischen zwei zu betonierenden Bauteilen, insbesondere zwischen einem Gebäude und einem vorkragenden Außenteil, bestehend aus einem dazwischen zu verlegenden Isolierkörper mit zumindest integrierten Druckelementen, die in eingebautem Zustand des Bauelementes im wesentlichen waagerecht und quer zur im wesentlichen waagerechten Längserstreckung des Isolierkörpers durch diesen hindurch verlaufen und jeweils an beide Bauteile anschließbar sind.The invention relates to a component for thermal insulation between two components to be concreted, in particular between a building and a cantilevered outer part, consisting of one to be installed in between Insulating body with at least integrated pressure elements, which in the installed state of the component essentially horizontally and transversely to the essentially horizontal longitudinal extent of the insulating body run through it and to both Components can be connected.
Mit Hilfe derartiger Bauelemente werden vorkragende Wandteile wie beispielsweise Balkone mit einer entsprechenden Zwischendecke eines Gebäudes unter weitgehendem Ausschluß von Kältebrücken verbunden. Zur Aufnahme von Druckkräften weisen die Druckelemente in der Regel an ihren Enden in den Betonbauteilen verankerte Druckplatten auf, die die Krafteinleitung in die Druckelemente begünstigen und die Verankerungslänge im Beton reduzieren.With the help of such components cantilever Wall parts such as balconies with a corresponding False ceiling of a building under extensive Exclusion of cold bridges connected. To record of pressure forces have the pressure elements in the Usually anchored at their ends in the concrete components Pressure plates on the force transmission into the pressure elements favor and the anchoring length in the concrete to reduce.
Derartige Druckplatten, die insbesondere scheibenförmig ausgebildet sind und prallel zur Längserstreckung des Isolierkörpers und senkrecht zu den durch den Isolierkörper verlaufenden Druckelementen angeordnet sind, haben allerdings den Nachteil, daß durch sie die Mittelachse der Druckelemente nicht beliebig tief im Wärmedämmungsbauelement angeordnet werden kann. Denn zum einen kann der Höhenversatz zwischen Mittelachse der Druckelemente und Druckplattenunterseite nicht in größerem Maße reduziert werden bei gleichzeitiger Aufrechterhaltung der Druckplattenfunktion und zum anderen muß unterhalb des Drucklagers eine bestimmte Beton-bzw. Isolierkörperdicke eingehalten werden, um die Druckplatte und somit das korrosionsgefährdete Druckelement vor Korrosion zu schützen. Hierdurch wird jedoch verhindert, was allgemein angestrebt wird, nämlich den Abstand zwischen Zug- und Druckelementen möglichst groß zu wählen, um hierdurch das auf das Druckelement übertragene Moment vergrößern zu können.Such printing plates, in particular disc-shaped are formed and parallel to the longitudinal extension of the Insulator and perpendicular to that through the insulator extending pressure elements are arranged however, the disadvantage that the central axis the pressure elements not as deep as possible in the thermal insulation component can be arranged. Because for one can the height offset between the central axis of the Printing elements and printing plate underside not in larger Dimensions are reduced while maintaining the printing plate function and the other a certain concrete or. Insulation body thickness to be adhered to Pressure plate and thus the corrosion-prone pressure element protect against corrosion. This will, however prevents what is generally sought, namely the distance between tension and compression elements if possible large to choose, thereby the on the pressure element to be able to enlarge transmitted moment.
Ein weiteres Bauelement der eingangs genannten Art ist aus DE-U 93 18 354 bekannt und weist Druckelemente aus Kunststoffmaterial auf, deren längere, wirksame Querschnittsachse die vertikale Achse ist, so daß sie auch zur Schubkraftaufnahme geeignet sein und auch eine gewisse seitliche Bewegung oder Querbewegung in horizontaler Richtung und quer zur Längserstreckung dieser Elemente zulassen sollen. Derartige Druckelemente besitzen aber gerade aufgrund ihrer vertikalen Orientierung den Nachteil eines verkleinerten Hebelarms der wirksamen Mittelachse der Druckelemente gegenüber der Zugstabachse, wodurch das durch das Druckelement übertragbare Moment entsprechend kleiner ausfällt.Another component of the type mentioned is known from DE-U 93 18 354 and has printing elements Plastic material whose longer, effective cross-sectional axis is the vertical axis so it too be suitable for shear force absorption and also a certain one lateral movement or lateral movement in horizontal Direction and transverse to the longitudinal extent of this Allow items. Such printing elements have but precisely because of their vertical orientation the disadvantage of a smaller lever arm effective central axis of the pressure elements compared to the Tension rod axis, whereby that which can be transmitted through the pressure element Moment is correspondingly smaller.
Es ist somit Aufgabe der vorliegenden Erfindung, ein Bauelement zur Wärmedämmung mit einem Druckelement zur Verfügung zu stellen, dessen geometrische Anordnung und Gestaltung die Übertragung größerer Momente als herkömmliche Lösungen ermöglicht, wobei jedoch die Wärmedämmeigenschaften nicht herabgesetzt werden sollen. It is therefore an object of the present invention Component for thermal insulation with a pressure element for To make available, its geometric arrangement and Design the transmission of larger moments than conventional ones Solutions enables, however, the thermal insulation properties should not be belittled.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Druckelemente jeweils mehrere in eingebautem Zustand des Bauelementes im wesentlichen vertikal verlaufende Druckstege aufweisen, die jeweils zu einem Profilkörper miteinander verbunden sind, wobei die Länge der Druckelemente in Richtung der Längserstreckung des Isolierkörpers, also die Länge der Anlage am angrenzenden Betonbauteil, ein Vielfaches ihrer vertikalen Höhe beträgt. Während sich bei den Druckelementen des Standes der Technik Vertikal- und Horizontalerstreckung in der Ebene der Fuge in der Regel nicht unterscheiden, da diese rotationssymmetrisch ausgeführt sind, zeichnet sich das Druckelement der vorliegenden Erfindung dadurch aus, daß es nur eine Orientierung des Druckelements innerhalb des Wärmedämmelementes gibt, die die Anforderungen an das Druckelement erfüllt. Denn das erfindungsgemäße Druckelement ist aufgrund der vertikalen, parallel zueinander verlaufenden Druckstege in Vertikalrichtung steif und somit knickstabil, hingegen in Horizontalrichtung schubbewegungsweich ausgebildet, wodurch es seitliche temperaturbedingte Längenänderungen des vorkragenden Außenteils gegenüber dem Gebäude nicht behindert. Bei einem fälschlicherweise um 90° gedrehten Einbau des Druckelementes ließe sich nur ein Bruchteil der Druckkräfte über längere Zeit aufnehmen.This object is achieved in that the pressure elements each have a plurality of vertically extending elements when the component is installed Have pressure bars, each to a profile body are interconnected, the length of the Pressure elements in the direction of the longitudinal extent of the insulating body, thus the length of the system on the adjacent one Concrete component that is a multiple of its vertical height. While the printing elements of the stand der Technik Vertical and horizontal extension in the The level of the joint usually does not differ as this are designed to be rotationally symmetrical Printing element of the present invention characterized in that there is only one orientation of the printing element within the Thermal insulation element that meets the requirements of the Pressure element met. Because the pressure element according to the invention is due to the vertical, parallel to each other running pressure bars in the vertical direction stiff and thus kink-resistant, but smooth in the horizontal direction trained, which makes it lateral temperature-related Changes in length of the projecting outer part not disabled in front of the building. At a installation of the pressure element incorrectly rotated by 90 ° could only be a fraction of the pressure forces record for a long time.
Somit ist das Druckelement für die Anforderungen, die für jede der verschiedenen Beanspruchungsrichtungen innerhalb der Fuge bestehen, durch richtungsabhängige Anpassung der Dimension der Druckstege optimal ausgelegt. Dies führt zu einer drastischen Materialersparnis.Thus, the printing element for the requirements that for each of the different stress directions within the joint exist by directional adjustment the dimension of the pressure bars optimally designed. This leads to drastic material savings.
Auf der anderen Seite führt das Vorsehen mehrerer Druckstege dazu, daß sich die Höhe jedes einzelnen Druckstegs reduzieren läßt, da sich die aufzunehmende Belastung entsprechend verteilt. On the other hand, the provision of several leads Pressure ridges that the height of each one Pressure web can be reduced because the Load distributed accordingly.
Die Vertikalrichtung der Druckstege besagt, daß zwar das gesamte Druckelement vom einen Bauteil ausgehend horizontal und damit quer zur Längserstreckung der Fuge zum anderen Bauteil verläuft, hierbei aber die Druckstege innerhalb dieses horizontal verlaufenden Druckelements zumindest teilweise vertikal angeordnet sind.The vertical direction of the webs says that the entire pressure element starting from one component horizontal and thus transverse to the longitudinal extent of the joint to the other component, but here the pressure bars within this horizontal pressure element are at least partially arranged vertically.
Zweckmäßigerweise sind die Druckstege durch zumindest einen hierzu quer verlaufenden Verbindungssteg verbunden, der in Richtung der Längserstreckung des Isolierkörpers entweder vertikal oder horizontal verläuft, eine gegenseitige Lagefixierung der Druckstege zueinander bewirkt und diese zu jeweils einem Profilkörper verbindet. Insbesondere besteht der Profilkörper aus zumindest drei Druckstegen und ist die Länge der Druckelemente zumindest dreimal so groß wie deren Höhe, wodurch sich für jedes Druckelement ein gutes Verhältnis zwischen dem Querschnitt bzw. der Druckelementhöhe und der Druckfestigkeit bzw. dem aufnehmbaren Moment ergibt.The pressure bars are expediently by at least connected a connecting web running transversely to this, that in the direction of the longitudinal extent of the insulating body is either vertical or horizontal, a mutual fixation of the webs to each other causes and this to a profile body connects. In particular, the profile body consists of at least three pressure bars and is the length of the pressure elements at least three times their height, which means a good relationship for each printing element between the cross section or the pressure element height and the compressive strength or the recordable torque.
Vorteilhafterweise erstrecken sich die Stege genau in Vertikalrichtung durch den Isolierkörper, um die Anforderung der vertikalen Steifigkeit und der horizontalen Schubweichheit zu gewährleisten. Bei bestimmten Ausgestaltungen der Druckstege kann sich jedoch auch deren Neigung aus der Vertikalen empfehlen, die in Teilbereichen 45° nicht übersteigen sollte.The webs advantageously extend exactly in Vertical direction through the insulator to meet the requirement vertical stiffness and horizontal To ensure thrust softness. With certain configurations however, the pressure bars can also be theirs Recommend inclination from the vertical, in some areas Should not exceed 45 °.
Zur weiteren Einsparung des Druckelementmaterials, was zu einer Erhöhung der Wärmedämmung führt, empfiehlt es sich, wenn die Druckstege mit sie im Bereich des Isolierkörpers durchdringenden Aussparungen versehen sind.To further save the printing element material, what it leads to an increase in thermal insulation if the pressure bars with them in the area of the insulating body penetrating recesses are provided.
Es ist darüberhinaus vorteilhaft, wenn die Druckelemente an den dem Betonbauteil zugewandten Seiten sich paralell zur Längsrichtung des Isolierkörpers erstreckende plattenförmige Kontaktprofile aufweisen, die zweckmäßigerweise gleichzeitig den Verbindungssteg ersetzen können, indem sie die Druckstege miteinander verbinden. Hierbei sind idealerweise die Kontaktprofilflächen, die zur Aufnahme der Druckkräfte dienen, im wesentlichen so groß bemessen wie der von den Druckstegen umschriebene Querschnittsbereich des Druckelements, so daß zumindest die vertikale Erstreckung des Druckelementes durch die Kontaktprofile nicht erhöht wird. Hierdurch läßt sich der Abstand des Kontaktprofils von der Unterkante des Isolierkörpers minimieren und somit aufgrund des größeren Hebelarms zwischen Druck- und Zugelementen das aufzunehmende Moment erhöhen. Die plattenförmige Gestaltung der Kontaktprofile umfaßt insbesondere auch rauhe, gerippte oder ganz allgemein mit Vorsprüngen versehene Oberflächen, die den Kontakt mit den angrenzenden Betonbauteilen verbessern.It is also advantageous if the pressure elements in parallel on the sides facing the concrete component extending to the longitudinal direction of the insulating body Have plate-shaped contact profiles, which are expedient at the same time replace the connecting bridge can by connecting the pressure bars with each other. Ideally, the contact profile surfaces are the serve to absorb the compressive forces, essentially so dimensioned as large as the one circumscribed by the pressure bars Cross-sectional area of the pressure element, so that at least the vertical extension of the pressure element through the Contact profiles is not increased. This allows the distance of the contact profile from the lower edge of the Minimize the insulating body and therefore due to the larger Lever arm between the push and pull elements that to be picked up Increase moment. The plate-shaped design the contact profile includes in particular rough, ribbed or generally provided with protrusions Surfaces that are in contact with the adjacent concrete components improve.
Darüber hinaus kann hierdurch das plattenförmige Kontaktprofil flacher und dafür breiter ausgeführt werden, da es auf seiner Rückseite in kurzen Abständen von den senkrecht hierzu verlaufenden Druckstege unterstützt und gegen Durchbiegen gesichert wird. Folglich muß das Kontaktprofil bei gleicher Kraftaufnahme keinen vertikalen Überstand gegenüber den ebenfalls in ihrer Höhe reduzierten Druckstegen aufweisen.In addition, the plate-shaped Contact profile flatter and therefore wider be there on its back at short intervals of the pressure bars running perpendicular to it is supported and secured against bending. Consequently, the contact profile must be the same Force absorption no vertical projection over the also have reduced pressure webs in height.
Somit ist offensichtlich, daß durch diese Lamellenbauweise die Bauhöhe des Druckelements einschließlich der Druckplatten verringert werden kann, ohne daß dies zu einem größeren Querschnittsbereich des Druckelementmaterials und somit zu einer größeren Wärmeleitung durch den Isolierkörper führen würde.So it is obvious that this slat construction including the overall height of the pressure element of the printing plates can be reduced without this to a larger cross-sectional area of the pressure element material and thus to greater heat conduction would lead through the insulating body.
Durch den lamellenartigen Aufbau der Druckelemente ergibt sich, daß die plattenförmigen Drucklager nicht größer als der von den Druckstegen umschriebene Querschnittsbereich ausgeführt werden müssen und dennoch die Lagerfläche größer als die Stegquerschnittsfläche im Isolierkörper ausgeführt ist, so daß die Drucklager ihre Funktion der Einleitung der Druckkräfte in das Druckelement gewährleisten können.Due to the lamellar structure of the pressure elements themselves that the plate-shaped thrust bearing is not larger than the cross-sectional area circumscribed by the pressure bars have to be executed and still the storage area is larger than the cross-sectional area of the web is carried out in the insulating body, so that the thrust bearing their function of introducing the compressive forces into the Can guarantee pressure element.
Zum einen ist es empfehlenswert, daß die Kontakprofile formschlüssig mit den angrenzenden Betonbauteilen verbunden sind, was durch einzelne, sich in den Beton erstreckende Vorsprünge, eine entsprechend ausgeführte Oberfläche oder durch ein sich in das Betonbauteil erstreckendes Kontaktprofil erfolgen kann. Hierdurch werden die horizontalen Schubbewegungen zwischen den beiden Bauteilen direkt auf das Druckelement übertragen, welches erfindungsgemäß schubbewegungsweich ausgeführt ist. Somit können Relativbewegungen zwischen den Betonbauteilen und dem Druckelement, welche zu einer Überbeanspruchung der Drucklageroberfläche bis hin zu deren Zerstörung führen können, verhindert werden. Zum anderen ist es aber auch empfehlenswert, wenn die Kontaktprofile zumindest teilweise in den Isolierkörper eingebettet sind und nur in geringem Maße in das Betonbauteil vorstehen, um so einen ausreichenden Abstand von der im Betonbauteil befindlichen Bewehrung einzuhalten. Hierdurch muß bei der Positionierung der Druckelemente nicht auf die Position der Bewehrungselemente Rücksicht genommen werden. Schließlich können ganz allgemein die Druckelemente und nicht nur die Kontaktprofile zumindest teilweise über den Isolierkörper hinausragen und im angrenzenden Betonbauteil verankert sein, um so einen Formschluß herzustellen, der insbesondere die Übertragung von Horizontalbewegungen begünstigt.First, it is recommended that the contact profiles positively connected to the adjacent concrete components are what by individual, extending into the concrete Projections, a correspondingly executed Surface or by extending into the concrete component Contact profile can take place. This will the horizontal thrust movements between the two Transfer components directly to the pressure element, which according to the invention is carried out smoothly is. This allows relative movements between the concrete components and the pressure element, which leads to an overuse the thrust bearing surface up to its Destruction can be prevented. On the other hand but it is also recommended if the contact profiles at least partially embedded in the insulating body are and only to a small extent in the concrete component protrude so as to maintain a sufficient distance of to comply with the reinforcement in the concrete component. This means that the positioning of the pressure elements not consider the position of the reinforcement elements be taken. Finally, in general, Pressure elements and not just the contact profiles at least partially protrude beyond the insulating body and be anchored in the adjacent concrete component, so one Establish positive locking, in particular the transmission favored by horizontal movements.
Besonders vorteilhaft ist es, wenn die Druckelemente aus insbesondere alkalibeständigem, faserverstärktem Kunststoff bestehen, beispielsweise aus glasfaserverstärkten Thermoplasten oder Duroplasten, da sich hierdurch eine geringere Wärmeleitung durch den Isolierkörper ergibt. Darüberhinaus braucht ein solches Kunststoffdruckelement keine Beton- bzw. Isoliermaterialüberdeckung, da es nicht korrisionsempfindlich ist. Vielmehr kann das Kunststoffdruckelement bündig mit den angrenzenden Betonbauteilen verlegt werden, wodurch die Handhabbarkeit verbessert wird.It is particularly advantageous if the pressure elements made in particular of alkali-resistant, fiber-reinforced Plastic, for example made of glass fiber reinforced Thermoplastics or thermosets, because of this less heat conduction through the insulating body results. In addition, such a plastic pressure element is required no concrete or insulating material covering, since it is not sensitive to corrosion. Rather, the plastic pressure element can be flush with the adjoining concrete components are laid, which means that Manageability is improved.
Im Fall des Einbaus eines Kunststoffdruckelementes ohne Betonüberdeckung empfiehlt es sich, wenn die Druckelemente auf ihrer Unterseite mit einem Brandschutzmaterial geschtürzt sind, da sie sonst im Falle eines Brandes schnell zerstört würden, woraufhin die ganze Lagerung erneuert werden müßte. Ein derartiges Brandschutzmaterial empfiehlt sich darüberhinaus auch für diejenigen Außenseiten des Isolierkörpers, die nicht von Beton beaufschlagt sind, da das Isoliermaterial hierdurch im Hinblick auf Wärme- bzw. Schalldämmung ausgelegt werden kann, ohne auf Brandschutzeigenschaften Rücksicht nehmen zu müssen. In the case of installing a plastic pressure element without Concrete cover is recommended if the pressure elements on the bottom with a fire protection material are fallen, otherwise they would be in the event of a fire would be destroyed quickly, whereupon the whole storage would have to be renewed. Such a fire protection material is also recommended for those Outside of the insulating body that is not made of concrete are acted on, since the insulating material thereby With regard to thermal or acoustic insulation can take fire protection properties into account to have to.
Eine Vereinfachung bei der Bestückung des Bauelements zur Wärmedämmung und eine Reduzierung des Verarbeitungsaufwandes ergibt sich dadurch, daß die Länge des Druckelementes der Länge des Isolierkörpers entsprechen kann und somit pro Isolierkörper nur ein Druckelement mit einer entsprechend großen Anzahl an Druckstegen zur Verfügung gestellt werden muß.A simplification in the assembly of the component for thermal insulation and a reduction in processing costs results from the fact that the length of the Pressure element correspond to the length of the insulating body can and therefore only one pressure element per insulator with a correspondingly large number of pressure bars for Must be made available.
Ebenso können die Druckelemente in Modulbauweise aus einzelnen Druckstegen und/oder Kontaktprofilen zusammengesetzt seien oder einzelne Druckelemente zu einem in der Länge variierbaren zusammengesetzten Druckelement kombiniert werden. Hierbei kann das Kombinieren über einen Verbindungssteg oder über geeignete Verbindungsmittel insbesondere durch gegenseitiges Verkleben, Anklipsen oder Verrasten erfolgen.The pressure elements can also be made in a modular design individual webs and / or contact profiles assembled be or individual printing elements to one composite pressure element variable in length be combined. Here, combining can via a connecting bridge or via suitable connecting means especially by mutual gluing, Clip on or snap into place.

Figur 2 ersichtlich - in der Fuge auch oberhalb des
Druckelementes 1, um eine Schall- und Wärmeübertragung
durch die Fuge zu verhindern.
Aus der Schnittdarstellung der Figur 2 ist außerdem zu
erkennen, daß die Länge des Druckelementes 1 in Richtung
der Längserstreckung des Isolierkörpers ein Vielfaches
seiner vertikalen Höhe beträgt, nämlich im vorliegenden
Fall das Doppelte.In addition to the
It can also be seen from the sectional view in FIG. 2 that the length of the
Figur 3 zeigt schließlich das Druckelement 1 in Seitenansicht
und läßt die Anordnung des Druckelementes innerhalb
der Fuge zwischen den beiden Betonbauteilen erkennen.
Hierbei ist insbesondere ersichtlich, daß das
Druckelement in der tiefstmöglichen Position innerhalb
der Fuge eingebaut werden kann, da insbesondere die
beiden plattenförmigen Kontaktprofile 3 und 4 nicht
gegenüber den Druckstegen 2 nach unten überstehen. Insbesondere
wenn das Druckelement 1 aus Kunststoff hergestellt
wird, unterliegt es auch dann keiner Korrosion,
wenn es bündig mit den Bauteilunterseiten in der Fuge
angeordnet wird und somit dem Umgebungsklima ausgesetzt
ist.Figure 3 finally shows the
Bei dem hier vorliegenden Ausführungsbeispiel liegen die Kontaktprofile 3 und 4 bündig an den beiden Betonbauteilen A und B an. Ebenso können diese jedoch auch mittels Vorsprüngen in den Betonbauteilen verankert sein bzw. sich teilweise oder vollständig in diese Betonbauteile flächig erstrecken. Are in the present embodiment the contact profiles 3 and 4 are flush with the two concrete components A and B. However, they can also do the same anchored in the concrete components by means of projections be or be partially or wholly in this Extend concrete components flat.
Die Figuren 4 bis 6 zeigen ein Druckelement 11, das
ähnlich dem Druckelement 1 aufgebaut ist, jedoch zu den
Druckstegen 12 zwei zusätzliche Verbindungsstege 13 und
14 (siehe Figuren 4 und 6) aufweist, die sich senkrecht
zu den Druckstegen 12 erstrecken und wiederum senkrecht
zueinander angeordnet sind. Mit Hilfe dieser Verbindungsstege
13 und 14 lassen sich insbesondere die Biegesteifigkeiten
und Druckfestigkeiten in den verschiedenen
Richtungen in geeigneter Weise steuern.Figures 4 to 6 show a
Die Figuren 7 bis 9 zeigen wiederum ein Druckelement
21, das sich von dem Druckelement 11 nur dadurch unterscheidet,
daß ein weiterer Verbindungssteg 25 parallel
zum Verbindungssteg 23 (der dem Verbindungssteg 13 aus
Figur 4 entspricht) vorgesehen ist.Figures 7 to 9 again show a
Schließlich ist in den Figuren 10 bis 12 eine Ausführungsform
eines Druckelementes 31 dargestellt. Dieses
Druckelement weist im Gegensatz zu den plattenförmigen
Druckstegen der Druckelemente 1, 11 und 21 solche
Druckstege 32 auf, die an ihren Enden bogenförmig auslaufen
und in die angrenzenden plattenförmigen Drucklager
33, 34 (siehe Figur 10) bzw. in die Verbindungsstege
35 bzw. 36 (siehe Figur 11) übergehen. Darüberhinaus
ist - wie aus Figur 12 erkennbar - jeder Drucksteg
32 mit einer Aussparung 37 versehen, um den Wärmeübergang
durch das Druckelement zu reduzieren.Finally, an embodiment is shown in FIGS. 10 to 12
a pressure element 31 shown. This

Zur Verbesserung der Wärme- und Schalldämmeigenschaften können die Zwischenräume zwischen den einzelnen Druckstegen in allen vier aufgezeigten Ausführungsformen mit Dämmmaterial versehen sein.To improve the heat and sound insulation properties can the spaces between the individual pressure bars in all four shown embodiments with Insulation material should be provided.
Zusammenfassend liegt der Vorteil der vorliegenden Erfindung darin, daß die Druckelemente aufgrund ihrer Lamellenbauweise in der tiefstmöglichen Position innerhalb der Fuge angeordnet werden können und selbst mit nur geringer Höhe ausgeführt sein können, wodurch das vom Druckelement aufzunehmende Moment vergrößert wird.In summary, the advantage of the present invention lies in that the pressure elements due to their lamella construction in the lowest possible position within the joint can be arranged and even with can only be carried out at a low height, which means that moment to be recorded by the pressure element is increased.
