Description

Technisches GebietTechnical area

Die vorliegende Erfindung beschreibt ein Kragplattenanschlusselement für den Einbau zwischen einer Boden- oder Deckenplatte und einer Kragplatte, umfassend einen wärmedämmenden Isolationskörper, durch den Druckelemente aus Beton mit jeweils einem Verbindungssteg und beidseitigen Druckauflageabschnitten sowie Zugmittel verlaufen, wobei das Kragplattenanschlusselement im eingebauten Zustand mit der Boden- oder Deckenplatte und der Kragplatte in Wirkverbindung steht.The present invention describes a cantilevered connection element for installation between a floor or ceiling plate and a cantilevered plate, comprising a heat-insulating insulation body, through which pressure elements made of concrete each have a connecting web and two-sided pressure bearing sections and traction means, wherein the cantilevered connection element in the installed state with the floor or ceiling plate and the cantilever is in operative connection.

Stand der TechnikState of the art

Kragplattenanschlusselemente besitzen üblicherweise eine Lage oberer Zugstäbe und eine Lage unterer Druckstäbe, sowie Elemente zur Aufnahme der Querkräfte, wobei die Bauteile mindestens teilweise innerhalb eines Isolationskörpers verlaufend oder querend angeordnet sind, wodurch das Kragplattenanschlusselement eine wärmedämmende Wirkung aufweist.Cantilever connection elements usually have a layer of upper tension rods and a layer of lower pressure rods, as well as elements for receiving the transverse forces, wherein the components are at least partially disposed within an insulating body extending or crossing, whereby the cantilever panel connection element has a heat-insulating effect.

Die EP34332 beschreibt statt der Verwendung von Druckstäben, Druckelemente, die innerhalb des Isolationskörpers von Kragplattenanschlusselementen verlaufend angeordnet sind. Diese Druckelemente sind einfache, über die gesamte Länge denselben Querschnitt aufweisende Stahlkörper, aus Rundstäben oder aus Stäben mit rechteckigem Querschnitt. Diese Stahlkörper wiesen somit über die gesamte Länge denselben Querschnitt auf.The EP34332 describes, instead of the use of pressure rods, pressure elements inside of the insulating body of Kragplattenanschlusselementen are arranged running. These pressure elements are simple, over the entire length of the same cross-section having steel body, round rods or rods of rectangular cross-section. These steel bodies thus had the same cross section over the entire length.

In einer Weiterentwicklung der Druckelemente ging man in der DE3403240 zu metallischen Druckelementen umfassend Abschnitte mit verschiedenen Querschnittsflächen über, nämlich zu Varianten mit einem Stababschnitt in der Isolationsplatte und mit Endplatten ausserhalb der Isolationsplatte, wodurch die Stabilität erhöht und der spezifische Flächenandruck des Druckelementes gesenkt werden konnte. Um die Korrosion der Druckelemente weitgehend vermeiden zu können, wurden rostfreie Stahlsorten verwendet.In an advancement of the pressure elements one went in the DE3403240 to metallic printing elements comprising sections with different cross-sectional areas, namely to variants with a rod portion in the insulation plate and with end plates outside the insulation plate, whereby the stability increased and the specific Flächenandruck the pressure element could be lowered. In order to avoid corrosion of the printing elements as far as possible, stainless steel grades were used.

Sowohl bei der Verwendung von Normalstahl als auch bei der Verwendung von nichtrostendem Stahl muss beim Einbau der Kragplattenanschlusselemente darauf geachtet werden, dass die sogenannte Überdeckung der metallischen Armierungsbauteile, der Abstand zwischen den Aussenflächen der Druckelemente und den Aussenflächen der Boden- oder Deckenplatte aus Beton, definierte Werte überschreiten. Andernfalls treten Korrosionsschäden in Form des Abplatzens von Beton auf, da die Druckelemente nicht ausreichend von Beton überdeckt sind.Both when using standard steel and when using stainless steel, when installing the cantilevered connection elements, care must be taken that the so-called overlap of the metal reinforcement components, the distance between the outer surfaces of the pressure elements and the outer surfaces of the concrete floor or ceiling slab, is defined Exceed values. Otherwise, corrosion damage occurs in the form of the spalling of concrete, since the pressure elements are not sufficiently covered by concrete.

Zur Verbesserung des Korrosionsschutzes offenbart die DE4033505 Kragplattenanschlusselemente mit Druckelementen, die korrosionsgeschützt eingepackt sind. Durch einen vor Korrosion schützenden Überzug, werden die Druckelemente bedeckt, wobei dieser Überzug gegen Verletzungen geschützt werden muss. Dieser Korrosionsschutz ist somit mit zusätzlichen Massnahmen verbunden und kompliziert und verteuert die Herstellung von Kragplattenanschlusselementen entsprechend.To improve the corrosion protection discloses the DE4033505 Cantilever plate connection elements with pressure elements that are protected against corrosion. An anti-corrosion coating covers the printing elements, protecting the coating against injury. This corrosion protection is thus associated with additional measures and complicates and increases the cost of manufacturing Kragplattenanschlusselementen accordingly.

Die meist aus Stahl gefertigten Druckelemente bilden eine Kältebrücke. Dies wurde erkannt und die DE-C-3302719 zeigt eine Lösung auf, bei der das Druckelement mehrteilig ist und aus einer gummielastischen Platte und zwei beidseitig angeordneten, vorzugsweise klebverbundene Druckverteilungselemente besteht. Auch diese Lösung ist fertigungstechnisch aufwendig und entsprechend teuer.The mostly steel-made printing elements form a cold bridge. This was recognized and the DE-C-3302719 shows a solution in which the pressure element is multi-part and consists of a rubber-elastic plate and two arranged on both sides, preferably adhesively bonded pressure distribution elements. This solution is also expensive to manufacture and correspondingly expensive.

Aus der DE-19652165 ist ein Kragplattenanschlusselement als Fertigbauteil bekannt, welches aus einer Fertigteilplatte mit zahnartigen Verlängerungen versehen ist, wobei diese Verlängerungen in Aussparungen im Isolationskörper eingreifen. Diese Lösung ist nur für Fertigbauteile geeignet und bedingt, dass die gesamte Fertigteilplatte mit den Druckaufnahmeverlagerungen aus ultrahochfestem Beton gefertigt ist, der äusserst kostspielig und schwer zu verarbeiten ist.From the DE-19652165 is a Kragplattenanschlusselement known as prefabricated, which is provided with a prefabricated plate with tooth-like extensions, these extensions engage in recesses in the insulating body. This solution is only suitable for prefabricated components and requires that the entire prefabricated panel with the pressure absorption displacements made of ultra-high-strength concrete, which is extremely expensive and difficult to work.

Eine Lösung, die sich gestalterisch exakt an bekannten Druckelementen aus Metall orientiert, ist aus der DE-10 2008 049 868 bekannt. Hier wird das Druckelement aus einem Verbindungssteg und daran beidseitig angeformten Druckverteilungsplatten angeformt sind, die aus den Isolationskörper heraus ragen und grösser sind als der Ausschnitt in dem Isolationskörper, den sie durchsetzen, gefertigt.A solution that is designed exactly to known pressure elements made of metal, is from the DE-10 2008 049 868 known. Here, the pressure element from a connecting web and on both sides molded pressure distribution plates are formed, which protrude from the insulation body and are larger than the cutout in the insulation body, they enforce made.

Ultrahochfester Beton vermag zwar extrem hohe Druckkräfte übertragen, doch ist das Material äusserst spröde und somit schlagempfindlich. Zudem ist die Aushärtezeit gross, so dass die Verwendung des Isolationskörpers selber als verlorene Schalung aus Platzgründen nicht in Frage kommt.Although ultrahigh-strength concrete can transmit extremely high compressive forces, the material is extremely brittle and therefore impact-sensitive. In addition, the curing time is great, so that the use of the insulating body itself as lost formwork for reasons of space is out of the question.

Aus der DE-3116381-A ist ein Kragplattenanschlusselement bekannt, welches als Druckelement eine ein- oder mehrmalige Scheibe vorsieht, die etwa mittig im Isolationskörper gehalten ist.From the DE-3116381-A is a Kragplattenanschlusselement known, which provides a single or multiple disc as a pressure element, which is held approximately centrally in the insulating body.

Letztlich ist aus der EP-1225282 A eine Lösung bekannt mit den Merkmalen des Oberbegriffes des Standes der Technik. Hierbei ragt das Druckelement ein- oder beidseitig aus der Isolationsplatte hinaus und greift mit dem auskragenden Teil in die Kragplatte und/oder in die Boden-Deckenplatte hinein. Da zwischen der Kragplatte einerseits und der Boden-Deckenplatte andererseits unterschiedliche Temperaturen und somit unterschiedliche Längendehnungsverhältnisse bestehen, wirken Schwerkräfte. Die Folge sind entweder Abplatzungen am Beton in denen das Druckelement hineinragt oder die Zerstörung des Druckelementes, welches ebenfalls aus Beton gefertigt ist.Ultimately, out of the EP-1225282A a solution known with the features of the preamble of the prior art. In this case, the pressure element protrudes on one or both sides of the insulation plate and engages with the projecting part in the cantilever and / or in the floor ceiling plate. As between the cantilever plate on the one hand and the floor ceiling plate On the other hand, different temperatures and thus different elongation ratios exist, gravitational forces act. The result is either flaking on the concrete in which the pressure element protrudes or the destruction of the pressure element, which is also made of concrete.

Es ist die Aufgabe der vorliegenden Erfindung ein Kragplattenanschlusselement der eingangs-genanten Art so zu verbessern, dass die zuvor beschriebenen Schädigungen vermieden werden können, ohne dass hierzu das aus Beton gefertigte Druckelement gesondert umhüllt sein muss, beispielsweise durch eine verlorene Schalung.It is the object of the present invention to improve a cantilever panel connection element of the aforementioned type such that the damage described above can be avoided without the pressure element made of concrete having to be wrapped separately, for example by a lost formwork.

Das Kragplattenanschlusselement 1 gemäss der Figur 1 weist einen Isolationskörper 8 auf, welcher in seiner Querrichtung von mindestens einem oberen Zugstab 2 und einem unteren Druckelement 5 durchsetzt ist. Entsprechend ihrer Bezeichnung nehmen die oberen Zugstäbe 2 Zugkräfte und die Druckelemente 5 Druckkräfte auf, wenn das Kragplattenanschlusselement 1 zwischen einer Boden- oder Deckenplatte B und einer Kragplatte K eingebaut und mit beiden Platten B, K wirkverbunden ist. Zusätzlich können bei dieser Version des Kragplattenanschlusselementes auch Querkraftstäbe 4 vorhanden sein. Die zwar angedeuteten Druckstäbe 3 sind nicht erforderlich, sondern können völlig durch die erfindungsgemäss gestalteten Druckelemente 5 ersetzt sein.The cantilever connection element 1 according to the FIG. 1 has an insulating body 8, which in its transverse direction of at least one upper tie rod 2 and a lower pressure element 5 is traversed. According to their designation, the upper tension rods 2 absorb tensile forces and the pressure elements 5 pressure forces when the cantilevered connection element 1 is installed between a floor or ceiling plate B and a cantilever K and is operatively connected to both plates B, K. In addition, in this version of the Kragplattenanschlusselementes also transverse force rods 4 may be present. Although indicated pressure rods 3 are not required, but can be completely replaced by the pressure elements 5 designed according to the invention.

Wie aus Figur 1 hervorgeht, queren die oberen Zugstäbe 2 den Isolationskörper 6 und ragen in die Boden- oder Deckenplatte B bzw. in die Kragplatte K zu beiden Seiten des Isolationskörpers 8. Wobei die Länge des in die Boden- oder Deckeplatte B hineinragenden Teils des oberen Zugstabes 2 grösser als die Dicke des Isolationskörpers 8 ist. Die oberen Zugstäbe 2 ragen aus dem Isolationskörper 8 in die benachbarte Boden- oder Deckenplatte B bzw. in die Kragplatte K hinein und werden dort einbetoniert. Zur Anwendung kommen neben Baustahl zur Vermeidung von Korrosion, korrosionsgeschützter Stahl bzw. rostfreier Stahl.How out FIG. 1 shows the upper tie rods 2 the insulation body 6 and protrude into the bottom or ceiling plate B or in the cantilever K on both sides of the insulating body 8. Where the length of the protruding into the bottom or top plate B part of the upper tie rod 2 larger as the thickness of the insulating body 8 is. The upper tension rods 2 protrude from the insulation body 8 into the adjacent floor or ceiling panel B or into the cantilever K and are embedded in concrete there. In addition to structural steel to prevent corrosion, corrosion-protected steel or stainless steel are used.

Während die Figur 1 eine herkömmliche Gestaltung des eigentlichen Kragplattenanschlusselementes 1 zeigt, ist in der Figur 2 eine neue Variante gezeigt, mit einer Schubplatte, wie aus den Dokumenten EP-A-0822299 und CH-A-00070/2008 bekannt. Diese Schubplatte überträgt durch den Isolationskörper hindurch sowohl die Zug- wie die Druckkräfte als auch die Querkräfte und erübrigt damit den Einsatz von Querstäben 4.While the FIG. 1 shows a conventional design of the actual cantilever panel connection element 1, is in the FIG. 2 a new variant shown, with a push plate, as from the documents EP-A-0822299 and CH-A-00070/2008 known. This push plate transmits through the insulating body through both the tensile and the compressive forces and the shear forces and thus eliminates the use of transverse bars. 4

Zur Übertragung der Druckkräfte, welche in der unteren Hälfte des Kragplattenanschlusselementes 1 auftreten, sind neben eventuellen Druckstäben 3 die Druckelemente 5 den Isolationskörper 8 in Querrichtung mindestens annähernd vollständig durchsetzend in Ausschnitte 80 des Isolationskörpers 8 eingesetzt. Die Querrichtung q des Kragplattenanschlusselementes 1 ist zur Veranschaulichung in Figur 2 gezeigt, während Figur 1 einen Schnitt in diese Querrichtung q verlaufend zeigt.In order to transmit the compressive forces which occur in the lower half of the cantilever panel connection element 1, in addition to any pressure rods 3, the pressure elements 5 are inserted into the insulation body 8 in the transverse direction at least approximately completely penetrating into cutouts 80 of the insulation body 8. The transverse direction q of Bracket plate connection element 1 is for illustrative purposes in FIG. 2 shown while FIG. 1 shows a section in this transverse direction q running.

Die Druckelemente 5 sind im Wesentlichen hantelartig ausgeführt und vollständig aus ultrahochfestem Beton in Gussformen 6 hergestellt. Die Druckelemente 5 verbleiben bis zur genügenden Aushärtung in den Gussformen 6 und können in der Gussform 6 in den wärmedämmenden Isolationskörper 8 in entsprechende Aussparungen 80 eingepresst, werden jedoch bevorzugt zuvor entformt. Hierzu weisen die Einweg-Gussformen 6 mindestens eine Reissnaht 61 (siehe Figur 3) auf. Bevorzugt sind zwei parallele Reissnähte 61 vorhanden, die einen wegreissbaren Streifen 62 definieren. Dieser Streifen 62 erstreckt sich wie die Reissnähte 61 über die gesamte achsiale Erstreckung der Einweggussformen und kann mit einer Reisslasche 63 versehen sein.The pressure elements 5 are designed substantially dumbbell-like and made entirely of ultra-high-strength concrete in molds 6. The pressure elements 5 remain until sufficient curing in the molds 6 and can be pressed in the casting mold 6 in the insulating insulating body 8 in corresponding recesses 80, but are preferably previously removed from the mold. For this purpose, the disposable molds 6 at least one tear seam 61 (see FIG. 3 ) on. Preferably, there are two parallel tear seams 61 defining a tear-away strip 62. This strip 62 extends like the tear seams 61 over the entire axial extension of the disposable molds and may be provided with a tear tab 63.

Durch die Verwendung von ultrahochfestem Beton ist sichergestellt, dass der Wärmeausdehnungskoeffizient und die Wärmeleitzahl der daraus hergestellten Druckelemente 5 in etwa den entsprechenden Werten der, dem Kragplattenanschlusselement 1 benachbarten, Boden- oder Deckenplatten B und Kragplatte K entspricht.The use of ultra-high-strength concrete ensures that the thermal expansion coefficient and the thermal conductivity of the pressure elements 5 produced therefrom approximately correspond to the corresponding values of the floor or ceiling panels B and cantilever K adjacent to the cantilevered connection element 1.

Ultrahochfester Beton (UHFB/englisch Ultra High Performance Concrete (UHPC)), wurde erst in den letzten Jahren immer weiter entwickelt und in dieser Anmeldung wird unter diesem Begriff Beton mit Druckfestigkeiten oberhalb von 150 N/mm2 verstanden. In der Praxis sind Druckfestigkeiten von bis zu 250 N/mm2 erreicht worden und theoretisch scheinen 800 N/mm2 möglich. Dieser ultrahochfeste Beton zeichnet sich neben einem Gehalt von Zement, Wasser und Gesteinskörnungen durch eine Beimengung von Zusatzstoffen, beispielsweise Mikrosilika und Quarzmehl aus, wobei Korngrössen von unter 0.125 mm eingesetzt werden. Ein weiterer entscheidender Unterschied zwischen UHFB und anderem Beton ist das geringere Wasser-Zement-Verhältnis von mindestens annähernd 0.2 im Vergleich zu Normalbeton ab 0.45 aufwärts. Dem UHFB können zusätzlich noch Fasern, beispielsweise aus Kunststoffen oder Metallen zugesetzt sein, wodurch die Sprödigkeit reduzierbar ist.Ultrahigh-strength concrete (UHFB / English Ultra High Performance Concrete (UHPC)), was only in recent years always further developed and in this application is understood by this term concrete with compressive strengths above 150 N / mm2. In practice, compressive strengths of up to 250 N / mm2 have been achieved and, theoretically, 800 N / mm2 seem possible. In addition to a content of cement, water and aggregates, this ultra-high-strength concrete is characterized by the addition of additives such as microsilica and quartz powder, with particle sizes of less than 0.125 mm being used. Another crucial difference between UHFB and other concrete is the lower water-cement ratio of at least approximately 0.2 compared to normal concrete from 0.45 upwards. The UHFB may additionally be added fibers, such as plastics or metals, whereby the brittleness is reducible.

Bevorzugt in den Druckelementen 5 eingesetzter UHFB weist Druckfestigkeiten von 150 MPa oder grösser, sowie Zugfestigkeiten von mindestens 10 MPa und Biegezugfestigkeiten von mehr als 30 MPa auf.UHFB preferably used in the printing elements 5 has compressive strengths of 150 MPa or greater, as well as tensile strengths of at least 10 MPa and bending tensile strengths of more than 30 MPa.

Aufgrund der extrem hohen Gefügedichte und geringen Porenanteilen des UHFB, ist UHFB nahezu dicht gegen Flüssigkeiten und Gase, was zu hoher Haltbarkeit und Widerstandsfähigkeiten führt, wodurch der Einsatz in Druckelementen 5 vorteilhaft ist.Due to the extremely high surface density and low pore content of the UHFB, UHFB is nearly impermeable to liquids and gases, resulting in high durability and resistance, making it advantageous to use in pressure elements 5.

Jedes untere Druckelement 5 weist drei einander folgende Abschnitte auf, einen mittleren Verbindungssteg 52, welcher mittig innerhalb des Isolationskörpers 6 angeordnet ist, sowie zwei an den Verbindungssteg 52 seitlich angrenzende Druckauflageabschnitte 50, wobei eine insgesamt etwa hantelförmige Ausgestaltung der unteren Druckelemente 5 resultiert. Der etwa hantelförmige Querschnitt des Druckelementes 5 liegt dabei in einer Ebene parallel zur Verlaufsebene von Boden- oder Deckenplatte B und Kragplatte K.Each lower pressure element 5 has three successive sections, a central connecting web 52, which is arranged centrally within the insulating body 6, and two to the connecting web 52 laterally adjacent Druckauflageabschnitte 50, wherein a total of about dumbbell-shaped configuration of the lower pressure elements 5 results. The approximately dumbbell-shaped cross section of the pressure element 5 lies in a plane parallel to the plane of the floor or ceiling plate B and cantilever K.

Die Druckauflageabschnitte 50 können als Platten mit etwa quadratischem Querschnitt ausgeformt sein, an welche sich die Übergänge 53 anschliessen. Diese Übergänge 53 haben die Gestalt von Pyramidenstümpfe mit quadratischen oder rechteckigen Grundrissen, welche den Druckauflageabschnitt entspricht.The pressure bearing sections 50 can be formed as plates with approximately square cross section, to which the transitions 53 connect. These transitions 53 have the shape of truncated pyramids with square or rectangular plan views, which corresponds to the pressure application section.

Die Länge des Verbindungsstegs 52 ist kürzer als die Dicke des Isolationskörpers 8 in Querrichtung q des Kragplattenanschlusselementes 1. Der Isolationskörper 8 des Kragplattenanschlusselementes weist die entsprechenden Ausschnitte 80 bzw. Ausnehmungen auf, sodass das Druckelement 5 von der unteren Längskante des Isolationskörpers 8 her eingepresst werden kann. Hierbei kommen die Endflächen 51 der quadratischen Druckauflageabschnitte 50 bündig mit dem Isolationskörpers 8 des Kragplattenanschlusselementes 1 zu liegen, wie dies in den Figur 1 und 2 dargestellt ist.The length of the connecting web 52 is shorter than the thickness of the insulating body 8 in the transverse direction q of the cantilevered connection element 1. The insulating body 8 of the cantilevered connection element has the corresponding cutouts 80 or recesses so that the pressure element 5 can be pressed in from the lower longitudinal edge of the insulating body 8 , Here, the end surfaces 51 of the square pressure bearing sections 50 are flush with the Insulating body 8 of the cantilever panel connection element 1 to lie, as shown in the FIGS. 1 and 2 is shown.

Besonders vorteilhaft ist auch, dass die untere Grundfläche der Druckelemente 5 mit der unteren Grundfläche des Isolationskörpers 8 bündig gestaltet sind. Dies ergibt sich, da der UHF Beton nicht korrodieren kann und somit keine Überdeckung erfordert. Dies erleichtert die Platzierung im Isolationskörper 8 und erlaubt eine nachträgliche Einsetzung eines Teiles des ausgeschnittenen Isolationskörpers.It is also particularly advantageous that the lower base surface of the pressure elements 5 are designed to be flush with the lower base surface of the insulating body 8. This results because the UHF concrete can not corrode and thus requires no overlap. This facilitates the placement in the insulating body 8 and allows a subsequent insertion of a part of the cut-out insulation body.

In der Figur 3 ist eine Vielzahl von Gussformen 6 zur Herstellung der erfindungsgemässen Druckelemente dargestellt. In diese Gussformen 6, die einseitig oder beidseitig offen sein können, lässt sich der ultrahochfeste Beton mit oder ohne einen Zuschlag von Fasermaterial einfüllen. Solche Formen lassen sich in dichter Anordnung nebeneinander aufstellen und problemlos füllen. Eine entsprechende Vorrichtung kann somit eine Vielzahl von Einlassdüsen aufweisen, mittels der simultan mehrere solcher Gussformen 6 gefüllt werden können und gleichzeitig können an derselben Vorrichtung sogenannte Vibrationsnadeln vorhanden sein, mittels denen der eingefüllte Beton verdichtet wird um so Lunkerbildungen zu vermeiden.In the FIG. 3 a plurality of molds 6 for the production of the novel printing elements is shown. In these molds 6, which can be open on one side or both sides, the ultra-high-strength concrete can be filled with or without a supplement of fiber material. Such forms can be placed next to each other in a dense arrangement and fill easily. A corresponding device can thus have a plurality of inlet nozzles, by means of which simultaneously several such molds 6 can be filled and at the same time so-called vibrating needles can be present on the same device, by means of which the filled concrete is compressed so as to avoid voids.

Einseitig oder beidseitig können dann auch an den jeweiligen Endflächen 51 Gleitfolien 7 aufgelegt sein.On one side or both sides can then be placed on the respective end surfaces 51 sliding films 7.

Wie aus den verschiedenen Ausführungsformen ersichtlich, kann die Länge des Verbindungssteges 52 beliebig variiert werden. Im Extremfall, wie in der Figur 3 gezeigt, kann der Verbindungssteg 52 praktisch zur Verbindungsfläche zwischen den beiden Übergängen 53 zusammenfallen. Die Länge des Verbindungssteges 52 ist abhängig von der Dicke des Isolationskörpers 8, in den das Druckelement 5 eingesetzt wird. Die Querschnittsgrösse des Verbindungssteges 52 und der Endflächen 51 steht im direkten Verhältnis zu den zu übertragenden Kräften. Je grösser diese Kräfte sind, umso grösser ist die Querschnittsfläche des Verbindungssteges 52 und umso grösser wählt man vorteilhafterweise auch die Grösse der Endfläche 51, um den spezifischen Druck pro Quadratmillimeter nicht über das erlaubte Mass steigen zu lassen. Der Druckauflageabschnitt 50 wird in seiner Dicke praktisch konstant gewählt. Dies ist in den verschiedenen Ausführungsformen deutlich erkennbar.As can be seen from the various embodiments, the length of the connecting web 52 can be varied as desired. In extreme cases, as in the FIG. 3 shown, the connecting web 52 can practically coincide with the connecting surface between the two transitions 53. The length of the connecting web 52 is dependent on the thickness of the insulating body 8, in which the pressure element 5 is used. The cross-sectional size of the connecting web 52 and the end surfaces 51 is in direct proportion to the forces to be transmitted. The greater these forces are, the greater the cross-sectional area of the connecting web 52, and the greater the choice of advantageously the size of the end face 51 in order not to allow the specific pressure per square millimeter to rise above the permitted level. The pressure bearing section 50 is selected to be practically constant in its thickness. This is clearly visible in the various embodiments.

Der ultrahochfeste Beton hat wesentlich geringere Wärmeleitfähigkeiten als ein entsprechendes Druckelement aus Stahl. Somit wird die wärmedämmende Eigenschaft des Kragplattenanschlusselementes 1 insgesamt verbessert. Die hier beschriebene Form des Druckelementes 5 erlaubt eine optimale Krafteinleitung bei gleichzeitiger Materialvolumenreduktion. Dies ist durchaus von Bedeutung, da der ultrahochfeste Beton wesentlich teurer als herkömmlicher Beton ist. Er ist jedoch preiswerter als ein entsprechendes gleich grosses Element aus einem rostfreien Stahl. Zudem werden hiermit auch Gewichtseinsparungen erzielt, die wiederum die Transportkosten senken, was nicht unrelevant ist, da Anlagen zur Verarbeitung von ultrahochfestem Beton äusserst kostspielig sind und man daher längere Transportwege in Kauf nehmen wird.The ultra-high-strength concrete has significantly lower thermal conductivities than a corresponding pressure element made of steel. Thus, the heat-insulating property of the cantilever panel connection element 1 is improved overall. The shape of the pressure element 5 described here allows an optimal introduction of force while reducing the volume of material. This is quite important, because the ultra-high-strength concrete much more expensive than conventional Concrete is. However, it is cheaper than a corresponding equal size element made of stainless steel. In addition, this also weight savings are achieved, which in turn reduce transport costs, which is not unimportant, since systems for processing ultra-high-strength concrete are extremely expensive and you will therefore take longer transport routes into account.

Neben der hier dargestellten Version mit quaderförmigen Stegen 52 und kegelstumpfförmigen Übergängen 53 ist es durchaus auch möglich den Steg 52 im Querschnitt rund oder oval zu gestalten. Daraus angepasst werden dann auch die Übergänge eher kegelstupfförmig gestaltet.In addition to the version shown here with parallelepiped webs 52 and frustoconical transitions 53, it is quite possible to make the web 52 in cross-section round or oval. Adapted from this, the transitions are also designed more cone-shaped.

Der Isolationskörper 8 wird üblicherweise aus geschäumten Polystyrol oder aus Stein- oder Glaswolle gefertigt. Glas- oder Steinwolle werden gemeinsam als Mineralwollenplatten bezeichnet. Geschäumter Polystyrol besitzt für die Verwendung im Bereich der Bausisolationen eine Druckfestigkeit von 0.15 bis 0.35 N/mm2. Die Mineralwolleplatten habe eine etwas höhere Druckfestigkeit und die liegt üblicherweise im Bereich von 0.5 bis 0.8 N/mm2. Während des Einbaus wirkt der Isolationskörper 8 des Kragplattenanschlusselement 1 praktisch als Abschalungselement. Während der Fertigung im Ortsbau liegt somit der statische Druck des flüssigen Betons am Isolationskörper 8 an. Hierdurch wird das Isolationsmaterial geringfügig zusammengepresst. Hierdurch vermindert sich die Dicke des Isolationskörpers 8 um ein gewisses Mass. Dieses Mass ist selbstverständlich abhängig von der Dicke des Isolationskörpers und dürfte in etwa 1% bis 5% liegen. Würde man diese Massveränderung nicht berücksichtigen so ragt das Druckelement im eingebauten Zustand in die Kragplatte beziehungsweise die Bodenbeziehungsweise Deckenplatte hinein. Erfindungsgemäss wird nun das Druckelement mit einem Untermass in den Isolationskörper eingebaut. Dieses Untermass wird so bemessen, dass nach dem Einbau des Kragplattenanschlusselementes 1 die Endfläche 51 der Druckelemente 5 praktisch plan in der Aussenfläche des Kragplattenanschlusselementes 1 zu liegen kommen. Dies ist in den Figuren 4a und 4b dargestellt. Figur 4a zeigt dabei den Zustand vor dem Einbau und Figur 4b den eingebauten Zustand. Da der Isolationskörper für die jeweiligen Kragplattenanschlusselemente für die jeweilige Anwendung exakt bemessen sind, lassen sich die auftretenden Druckverhältnisse relativ exakt berechnen und hieraus ergeben sich auch die entsprechenden Längenveränderungen. Die Abweichung der Lage der Endflächen 51 relativ zu den Aussenflächen des Isolationskörpers 8 sind daher gering. Bei auftretenden Relativbewegungen zwischen der Kragplatte und der Boden- beziehungsweise Deckenplatte führt nun nicht mehr zu Zerstörungen. Falls erwünscht, lassen sich die Druckelemente 5 an den Endflächen 51 zusätzlich mit Gleitfolien schützen.The insulating body 8 is usually made of foamed polystyrene or stone or glass wool. Glass or rock wool are collectively called mineral wool plates. Foamed polystyrene has a compressive strength of 0.15 to 0.35 N / mm 2 for use in the field of building insulation. The mineral wool panels have a slightly higher compressive strength and is usually in the range of 0.5 to 0.8 N / mm 2 . During installation, the insulating body 8 of the cantilever panel connection element 1 practically acts as a shuttering element. During production in the local structure thus the static pressure of the liquid concrete is applied to the insulating body 8. As a result, the insulation material is slightly compressed. hereby the thickness of the insulating body 8 decreases by a certain amount. This dimension is of course dependent on the thickness of the insulating body and should be in about 1% to 5%. If you did not consider this mass change so the pressure element protrudes when installed in the cantilever or Bodenbeziehungsweise ceiling plate. According to the invention, the pressure element is now fitted with an undersize in the insulation body. This undersize is dimensioned so that after installation of the cantilever panel connection element 1, the end face 51 of the pressure elements 5 come to lie practically flat in the outer surface of the cantilever panel connection element 1. This is in the FIGS. 4a and 4b shown. FIG. 4a shows the condition before installation and FIG. 4b the installed state. Since the insulation body for the respective cantilever panel connection elements for the respective application are precisely dimensioned, the pressure conditions occurring can be calculated relatively accurately and from this results also the corresponding changes in length. The deviation of the position of the end surfaces 51 relative to the outer surfaces of the insulating body 8 are therefore small. When occurring relative movements between the cantilever and the floor or ceiling plate now no longer leads to destruction. If desired, the printing elements 5 can be additionally protected on the end surfaces 51 with sliding films.
