Abstract

The element (1) has a thrust plate (3) penetrating an insulating body (2) and running perpendicular to a longitudinal extension, where the length of the thrust plate is same as the width of the insulating body. One of U-shaped handles (6) made of reinforcing steel is attached to both vertical faces (7) of the thrust plate, where the vertical faces run in a plane stretched by the thrust plate. Upper and lower side pieces (60, 61) of the handles run away protruding from the thrust plate. A connecting piece (62) between the side pieces of the handles runs straight.

Description

Die vorliegende Erfindung betrifft ein wärmedämmendes Kragplattenanschlusselement, mit einem Isolationskörper und mindestens einer Schubplatte, welche den Isolationskörper durchsetzt und senkrecht zu dessen Längsausdehnung verläuft, wobei die Schubplatte beidseitig mit ihren Stirnseiten aus der Isolationsplatte hinausragt.The present invention relates to a heat-insulating cantilever connection element, comprising an insulation body and at least one thrust plate, which passes through the insulation body and extends perpendicular to its longitudinal extent, wherein the thrust plate protrudes on both sides with their end faces from the insulation plate.

Wärmedämmende Kragplattenanschlusselemente sind seit Anfang der 1980er Jahren bekannt. Durch wärmedämmende Kragplattenanschlusselemente werden gegenüber dem Gebäudekörper auskragende Platten mit dem Baukörper verbunden. Üblicherweise besitzen sowohl die Bodendeckenplatte als auch die Kragplatte je ein unteres und ein oberes Armierungsnetz und die Kragplattenanschlusselemente verbinden diese Netze über die Fuge hinweg zwischen diesen beiden Platten. Hierzu weisen die bekannten Kragplattenanschlusselemente obere Zugstäbe und untere Drucksstäbe auf. Die Zugstäbe und die Druckstäbe durchsetzen den Isolationskörper.Heat-insulating cantilever connection elements have been known since the early 1980s. By insulating Kragplattenanschlusselemente over the building body projecting plates are connected to the building. Usually, both the bottom cover plate and the cantilever plate each have a lower and an upper reinforcing mesh and the Kragplattenanschlusselemente connect these networks across the joint between these two plates. For this purpose, the known Kragplattenanschlusselemente upper tie rods and lower pressure bars. The tension rods and the pressure rods pass through the insulation body.

So zeigt beispielsweise bereits die EP 0 034 332 ein derartiges Kragplattenanschlusselement. Allerdings ist nur der Zugstab als Stab ausgeführt, während statt des Druckstabes ein Druckelement im unteren Bereich den Isolationskörper durchsetzt. Zusätzlich ist zur Aufnahme der Querkräfte ein Querkraftstab vorhanden, mittels dem die Querkräfte beziehungsweise Schubkräfte übernommen werden.For example, shows the already EP 0 034 332 Such Kragplattenanschlusselement. However, only the tension rod is designed as a rod, while instead of the pressure rod, a pressure element in the lower region passes through the insulation body. In addition, a transverse force rod is provided for receiving the transverse forces, by means of which the transverse forces or shear forces are taken over.

Bei der Verwendung von Querkraftstäben ist die Einbaulage des Kragplattenanschlusselementes exakt definiert. Ein falscher Einbau führt entsprechend zu Schäden. Um dies zu vermeiden, zeigt die EP 0 119 165 ein Kragplattenanschlusselement bei dem die Zug- und Druckstäbe als geschlossenen Schlaufen ausgebildet sind um so eine symmetrische Anordnung zu erreichen und die Querkräfte durch das geschlossene System der Schlaufen aufzufangen ohne das hierzu spezielle Querkraftstäbe erforderlich sind.When using transverse force bars, the installation position of the cantilevered connection element is exactly defined. Incorrect installation will result in damage. To avoid this, shows the EP 0 119 165 a Kragplattenanschlusselement in which the tension and compression bars are designed as closed loops so as to achieve a symmetrical arrangement and absorb the transverse forces through the closed system of loops without this special shear force rods are required.

Ein völlig anderes Konzept zeigt hingegen die EP 0 499 590 . Hier sind die Zug- und Druckstäbe durch den Isolationskörper hindurchgeführt, während distanziert dazu, zwischen zwei benachbarten oberen Zugstäben und unteren Druckstäben, jeweils eine Schubplatte integriert ist. Diese Schubplatte übernimmt die Übertragung der Querkräfte und sie ragt beidseitig einerseits in die Bodendeckenplatte und andererseits in die Kragplatte hinein. Die Schubplatten sind untereinander durch querverlaufende Stäbe parallel zur Längsrichtung des Isolationskörper verlaufend miteinander verbunden. Optional sind schliesslich auch noch die Enden der Zugstäbe und Druckstäbe über sogenannte Endplatten miteinander verbunden um die erforderliche Festigkeit zu erreichen. Diese Endplatten sind jedoch statisch nicht erforderlich sondern erleichtern und erhöhen lediglich die Festigkeit des Kragplattenanschlusselementes bei dessen. Durch die Vielzahl der verschiedenen Stäbe und Schubplatten die durch den Isolationskörper hindurch geführt werden müssen, ist die Fertigung eines solchen Kragplattenanschlusselementes aufwendig.A completely different concept, however, shows the EP 0 499 590 , Here, the tension and compression rods are passed through the insulation body, while distanced to, between two adjacent upper Zugstäben and lower pressure rods, each a thrust plate is integrated. This thrust plate takes over the transfer of the shear forces and it protrudes on both sides, on the one hand in the ground cover plate and on the other hand into the cantilever. The thrust plates are mutually parallel by transverse bars Longitudinal direction of the insulating body running connected to each other. Optionally, finally, the ends of the tension rods and pressure rods are connected to each other via so-called end plates to achieve the required strength. However, these end plates are not required statically but facilitate and only increase the strength of the cantilever plate connection element in its. Due to the large number of different rods and thrust plates which must be guided through the insulation body, the production of such cantilever panel connection element is expensive.

Vom selben Anmelder wurde dieses Kragplattenanschlusselement geringfügig dadurch verbessert, dass zusätzlich die Zugstäbe und Druckstäbe durch aufgeschweisste, parallel zur Längsrichtung des Isolationskörpers verlaufenden Querstäben vereinfacht um so die Endplatten zu vermeiden. Diese Lösung ist in der CH 689 231 offenbart.By the same applicant, this cantilever panel connection element has been slightly improved by additionally simplifying the tension bars and pressure bars by means of welded-on transverse bars running parallel to the longitudinal direction of the insulating body so as to avoid the end plates. This solution is in the CH 689,231 disclosed.

Es wurde erkannt, dass es wenig sinnvoll ist die Zugstäbe und Druckstäbe von den Schubplatten distanziert separat durch den Isolationskörper hindurch zu führen. Entsprechend wird in der EP 0 822 299 vorgeschlagen die Zugstäbe und die Druckstäbe entlang der oberen beziehungsweise der unteren Längskante der Schubplatte anzuschweissen, wodurch mit sehr viel weniger Aufwand alle statischen Bedingungen erfüllt werden konnten.It was recognized that it makes little sense to keep the tie rods and push rods spaced from the push plates separately through the insulator body. Accordingly, in the EP 0 822 299 proposed to weld the tension rods and the pressure rods along the upper or lower longitudinal edge of the thrust plate, which could be met with much less effort all static conditions.

All diese Lösungen bilden Optimierungen zur Erfüllung der immer gleichen statischen Bedingungen. Dabei müssen selbstverständlich auch Kompromisse eingegangen werden. So ist es selbstverständlich vorteilhaft, wenn die Höhe der Schubplatte möglichst maximal ausgelegt werden kann. Bei der zuletzt genannten Lösung gemäss der EP 0 822 299 ist dies jedoch nur bedingt möglich, da die Zugstäbe beziehungsweise Druckstäbe entlang der oberen Kanten der Schubplatte verlaufen, beeinflusst dies automatisch dass die Höhe der Schubplatte maximal der Distanz zwischen Zugstäben und Druckstäben entspricht. Diese Höhe wird durch den Betonkörper vorgegeben und ist wesentlich geringer als die Dicke der Kragplatte beziehungsweise der Bodendeckenplatte, da sowohl die Zugstäbe als auch die Druckstäbe eine festgelegte minimale Betonüberdeckung verlangen.All these solutions form optimizations to fulfill the same static conditions. Of course, compromises must be made. So it is of course advantageous if the height of the thrust plate can be designed as maximum as possible. In the latter solution according to the EP 0 822 299 However, if this is only possible to a limited extent, since the tension rods or pressure rods run along the upper edges of the thrust plate, this automatically influences that the height of the thrust plate corresponds at most to the distance between tension rods and pressure rods. This height is dictated by the concrete body and is much smaller than the thickness of the cantilever plate or the floor cover plate, since both the tension bars and the pressure bars require a specified minimum concrete coverage.

Die Integration sowohl der Zug- und Druckstäbe als auch der Schubplatte in dem Isolationskörper ist problematisch, insbesondere da der Durchmesser der Zug- und Druckstäbe grösser ist als die Dicke der Schubplatte. Ein Einlegen dieser Elemente in den Isolationskörper, verlangt dass in diesen entsprechende Ausnehmungen angebracht sind. Dabei verbleiben Spalten durch die oftmals gewisse Betonmengen durchdringen können und damit unerwünschte Nebeneffekte auftauchen können.The integration of both the tension and compression rods and the thrust plate in the insulation body is problematic, especially since the diameter of the tension and compression rods is greater than the thickness of the thrust plate. An insertion of these elements in the insulating body, requires that appropriate recesses are mounted in these. This leaves columns through which often certain amounts of concrete can penetrate and thus undesirable side effects can occur.

Es ist daher die Aufgabe der vorliegenden Erfindung ein wärmedämmendes Kragplattenanschlusselement zu schaffen, welches optimaler auf die Gegebenheiten angepasst ist und mit dem entsprechend bei gleichen Querschnitten der Zug- und Druckstäbe höhere Kräfte übertragen werden können.It is therefore the object of the present invention to provide a heat-insulating cantilever connection element, which is more optimally adapted to the circumstances and with the corresponding higher cross-sections of the tension and compression rods higher forces can be transmitted.

Diese Aufgabe löst ein wärmedämmendes Kragplattenanschlusselement, welches die Merkmale des Patentanspruches 1 aufweist.This object is achieved by a heat-insulating cantilever connection element, which has the features of claim 1.

In der Zeichnung ist ein bevorzugtes Ausführungsbeispiel des Erfindungsgegenstandes in vereinfachter Form dargestellt und anhand der nachfolgenden Beschreibung erläutert. Es zeigt:

In der Zeichnung ist das Kragplattenanschlusselement insgesamt mit 1 bezeichnet. Das Element umfasst eine Wärmedämmplatte beziehungsweise einen Isolationskörper 2 dessen Höhe der Dicke der Bodendeckenplatte beziehungsweise der Kragplatte entspricht. Die Bodendeckenplatte, die selbstverständlich nicht Teil der Erfindung ist, ist mit 10 bezeichnet. In fluchtender Fortsetzung der Bodendeckenplatte 10 verläuft die Kragplatte 20. Zwischen der Bodendeckenplatte 10 und der Kragplatte 20 verläuft die Fuge 30. Die Fuge 30 bestimmt somit die Dimension des Isolationskörpers 2. Dieser Isolationskörper 2 wird üblicherweise aus den bekannten Wärmedämmmaterialien gefertigt. Insbesondere Glaswolle, Steinwolle und geschäumte Kunststoffmaterialien kommen hierfür in Frage und sind auf dem Markt als Platten unterschiedlicher Dicken erhältlich.In the drawing, the cantilever connection element is designated overall by 1. The element comprises a heat insulation board or an insulation body 2 whose height corresponds to the thickness of the ground cover plate or the cantilever plate. The bottom cover plate, which of course is not part of the invention, is designated 10. In alignment continuation of the bottom cover plate 10 extends the cantilever 20. Between the bottom cover plate 10 and the cantilever 20 extends the joint 30. The joint 30 thus determines the dimension of the insulating body 2. This insulating body 2 is usually made of the known thermal insulation materials. In particular, glass wool, rock wool and foamed plastic materials come into question and are available on the market as plates of different thicknesses.

Die statisch relevanten Teile des Kragplattenanschlusselementes bestehen aus den Schubplatten 3, die senkrecht zur Verlaufsrichtung der Fuge angeordnet sind und damit auch senkrecht zur Längsachse A des Isolationskörpers 2 verlaufen. Die Schubplatten 3 sind untereinander parallel und in regelmässigen Abständen verlaufend angeordnet. Bevorzugterweise wird man diese Schubplatten 3 aus rostfreiem Stahl fertigen. Selbstverständlich ist es jedoch auch möglich die Platten aus einem üblichen Baustahl zu fertigen und mit einem Korrosionsschutzmittel zu versehen. Die Schubplatten sind bevorzugterweise absolut eben und haben in der Ausführungsform gemäss den Figuren 1 und 2 eine rechteckige Grundform. Die oberen und unteren Horizontalkanten enden etwa auf der Höhe der oberen Armierungsnetze 11 in der Bodendeckenplatte 10 beziehungsweise auf der Höhe der oberen Armierungsnetze 21 in der Kragplatte 20 sowie unten auf der Höhe der unteren Armierungsnetze 12 beziehungsweise 22 in der Bodendeckenplatte 10 beziehungsweise der Kragplatte 20. Prinzipiell ist diese Relation jedoch nicht zwingend. Die Schubplatte kann auch höher oder weniger hoch ausgestaltet sein als hier dargestellt und beschrieben.The statically relevant parts of the Kragplattenanschlusselementes consist of the thrust plates 3, which are arranged perpendicular to the direction of the joint and thus also perpendicular to the longitudinal axis A of the insulating body 2. The thrust plates 3 are arranged mutually parallel and extending at regular intervals. Preferably, these thrust plates 3 will be made of stainless steel. Of course, it is also possible to produce the plates of a standard structural steel and to provide with a corrosion inhibitor. The push plates are Preferably absolutely flat and have in the embodiment according to the Figures 1 and 2 a rectangular basic shape. The upper and lower horizontal edges end approximately at the level of the upper Armierungsnetze 11 in the bottom cover plate 10 and at the height of the upper Armierungsnetze 21 in the cantilever 20 and at the bottom of the lower Armierungsnetze 12 and 22 in the bottom cover plate 10 and the cantilever 20th In principle, however, this relation is not mandatory. The pusher plate can also be made higher or less high than shown and described here.

Die Breite der Schubplatte 3 entspricht mindestens der Dicke des Isolationskörpers, doch ist sie bevorzugterweise länger und ragt daher beidseitig aus dem Isolationskörper 2 hinaus. Der Überstand der Schubplatte 3 ist mit 5 bezeichnet. Dieser Überstand 5 ist so gewählt, dass dieser mindestens der Mindestüberdeckung der Armierung entspricht. Im Normalfall entspricht dies etwa mindestens 10 maximal 30 Millimeter.The width of the thrust plate 3 corresponds at least to the thickness of the insulating body, but it is preferably longer and therefore protrudes on both sides of the insulating body 2 addition. The supernatant of the thrust plate 3 is denoted by 5. This supernatant 5 is chosen so that it corresponds to at least the minimum coverage of the reinforcement. Normally, this corresponds to at least 10 to a maximum of 30 millimeters.

Die vertikalen Stirnseiten der Schubplatte 3 sind mit 7 bezeichnet. An diesen vertikalen Stirnseiten 7 sind Bügel 6 angeschweisst. Diese Bügel 6 sind U-förmig gestaltet. Die Bügel 6 weisen obere Schenkeln 60 und untere Schenkel 61 auf, die parallel zueinander verlaufen und über ein Verbindungsstück 62 miteinander verbunden sind. Gemäss der Version die in den Figuren 1 und 2 dargestellt ist, ist dieses Verbindungsstück 62 gerade verlaufend und ist über deren gesamten Länge oder einer Teillänge über eine Schweissnaht 8 mit der Stirnseite 7 der Schubplatte 3 fest verbunden. Die Länge der Verschweissung beziehungsweise der Schweissnaht 8 muss mindestens der statisch erforderlichen Länge entsprechen. Dies ist für den Fachmann eine übliche Festigkeitsberechnung. Bei kleinen Dimensionen wird die Schweissnaht praktisch über die gesamte Länge des Verbindungsstückes 62 verlaufen, während bei Kragplattenanschlusselemente für dicke Kragplatten lediglich im oberen und unteren Bereich Schweissnähte mit je einer Länge von beispielsweise 20 - 60 mm genügen. Oben auf den oberen Schenkel 60 ist das obere Armierungsnetz 21 aufliegend verlegt während der untere Schenkel 61 auf ein unteres Armierungsnetz 22 aufliegt. Diese oberen Netze 11, 21 in der Bodendeckenplatte 10 beziehungsweise Kragplatte 20 werden bauseitig mit entsprechenden Abbinddrähten miteinander verbunden. Die hier dargestellte Verlegungsart ist eine mögliche Verlegungsart, jedoch nicht die verbreiteste. Häufiger werden die Kragplattenanschlusselemente zuerst verlegt und danach die Armierungsnetze 21, 22 gelegt. Dabei ist es üblicher das untere Armierungsnetz 22 auf die obere Seite der unteren Schenkel 61 aufzulegen, während das obere Armierungsnetz 21 unter den oberen Schenkeln 60 der Bügel 6 gelegt wird. Bei dieser Verlegungsweise kommen die Drähte der Netze die parallel zu den Schenkeln 60 beziehungsweise 61 verlaufen in dieselbe Ebene zu liegen und wären somit nicht sichtbar.The vertical end faces of the thrust plate 3 are denoted by 7. At these vertical end faces 7 bracket 6 are welded. These brackets 6 are U-shaped. The brackets 6 have upper legs 60 and lower legs 61, which are parallel to each other and connected to each other via a connecting piece 62. According to the version in the Figures 1 and 2 is shown is this connector 62 is straight and is firmly connected over its entire length or a partial length via a weld 8 with the end face 7 of the thrust plate 3. The length of the weld or the weld 8 must be at least the statically required length. This is a normal strength calculation for the person skilled in the art. For small dimensions, the weld will run virtually over the entire length of the connecting piece 62, while in Kragplattenanschlusselemente for thick cantilevers only in the upper and lower weld seams, each with a length of for example 20 - 60 mm suffice. At the top of the upper leg 60, the upper reinforcing mesh 21 is laid resting while the lower leg 61 rests on a lower reinforcing mesh 22. These top nets 11, 21 in the bottom cover plate 10 and cantilever 20 are connected to each other with appropriate Abbinddrähten on site. The type of installation shown here is one possible way of laying, but not the most common one. More often, the Kragplattenanschlusselemente be laid first and then the Armierungsnetze 21, 22 laid. It is more common to place the lower reinforcement net 22 on the upper side of the lower legs 61, while the upper reinforcing mesh 21 is placed under the upper legs 60 of the bracket 6. In this way of laying the wires of the nets come parallel to the legs 60 and 61, respectively are in the same plane and would therefore not be visible.

Die oberen Schenkel 60 aller Bügel 6 und die unteren Schenkel 61 können auch jeweils mittels einem aufgeschweissten Querstab 9 miteinander verbunden sein. Diese Querstäbe 9 sind aus statischen Gründen nicht zwingend Teil der Kragplattenanschlusselemente. Die Querstäbe 9 dienen lediglich der Erhöhung der Festigkeit des Kragplattenanschlusselementes selbst und erhöht deren Handlichkeit beim Transport. Zudem können diese Querstäbe zur Verbindung der bereits erwähnten Netze 11, 21 beziehungsweise 12, 22 dienen. Zu demselben Zweck kann auch auf dem Verbindungsstück 62 ein Querstab 9' aufgeschweisst sein. Hierdurch sind die Schubplatten 3 nicht nur durch den Isolationskörper 2 relativ zueinander verbunden sondern auch durch diese Querstäbe 9 beziehungsweise 9' womit das ganze Kragplattenanschlusselement 1 eine erhöhte Festigkeit erhält.The upper leg 60 of all the bracket 6 and the lower leg 61 can also be connected to each other by means of a welded transverse bar 9. These cross bars 9 are not necessarily part of the cantilever plate connection elements for static reasons. The cross bars 9 serve only to increase the strength of the cantilever panel connection element itself and increases their handling during transport. In addition, these cross bars for connecting the already mentioned networks 11, 21 and 12, 22 serve. For the same purpose, a transverse bar 9 'can also be welded on the connecting piece 62. As a result, the thrust plates 3 are not only connected by the insulating body 2 relative to each other but also by these cross bars 9 and 9 'whereby the whole Kragplattenanschlusselement 1 receives increased strength.

In der Figur 3 ist eine Alternative des erfindungsgemässen Kragplattenanschlusselementes gezeigt. Das Kragplattenanschlusselement 1 ist wiederum mit einem Isolationskörper 2 versehen und durch diesen Isolationskörper 2 erstrecken sich quer zu deren Längsausdehnung und somit senkrecht zur Fugenlängsrichtung wiederum die Schubplatten 3. An den Schubplatten 3 sind in der Ebene, welche die Schubplatte aufspannt beidseitig wiederum Bügel 6 angeordnet.In the FIG. 3 an alternative of the invention Kragplattenanschlusselementes is shown. The Kragplattenanschlusselement 1 is in turn provided with an insulating body 2 and through this insulating body 2 extend transversely to the longitudinal extent and thus perpendicular to the joint longitudinal direction turn the thrust plates 3. At the thrust plates 3 are in the plane which spans the thrust plate on both sides again arranged bracket 6.

Diese Bügel 6 sind zwar wiederum U-förmig, doch im Gegensatz zum zuvor beschriebenen Beispiel verlaufen die Verbindungsstücke 62 in einem Halbkreis. Die vertikalen Stirnseiten 7 sind entsprechend im gleichen Radius gekrümmt ausgeschnitten. Die Schweissnaht 8 folgt entsprechend dieser Krümmung. Die Schubplatte 3 ist in dieser Version etwas höher als der Abstand der beiden parallelen Schenkel 60 und 61. Dies ist jedoch nicht zwingend und die Höhe der Schubplatte 3 kann auch geringer sein als der Abstand der Schenkel 60 und 61 der Bügel 6. Auch hier sind mittels Querstäben 9 die Verbindungstücke 62 und damit die Bügel 6 untereinander verbunden. Bei der Wahl dieser Ausführungsform werden grössere Biegeradien realisiert und entsprechend können die Bügel 6 als Armierungseisen mit einem wesentlich grösseren Querschnitt verwendet werden, so dass entsprechend auch hohe statische Kräfte übertragen werden können.Although these brackets 6 are again U-shaped, but in contrast to the example described above, the connecting pieces 62 extend in a semicircle. The vertical end faces 7 are cut corresponding curved in the same radius. The weld 8 follows according to this curvature. The thrust plate 3 is in this version slightly higher than the distance between the two parallel legs 60 and 61. However, this is not mandatory and the height of the thrust plate 3 may also be less than the distance between the legs 60 and 61 of the bracket 6. Again, here by means of transverse rods 9, the connecting pieces 62 and thus the bracket 6 connected to each other. In the choice of this embodiment, larger bending radii are realized and according to the bracket 6 can be used as a reinforcing bar with a much larger cross-section, so that correspondingly high static forces can be transmitted.

Sowohl bei dieser Lösung als auch bei der zuvor beschriebenen Lösung lassen sich die oberen Schenkel 60 beziehungsweise die unteren Schenkel 61 durch entsprechende Wahl der Höhe der Schubplatte 3 so gestallten, dass die horizontale Kante 4 mit der entsprechenden Oberseite der oberen Schenkel 60 beziehungsweise mit der untersten Kante der unteren Schenkel 61 fluchtend verlaufen.Both in this solution and in the solution described above, the upper leg 60 and the lower leg 61 can be made by appropriate choice of the height of the thrust plate 3 so that the horizontal edge 4 with the corresponding top of the upper leg 60 and the lowest Edge of the lower legs 61 are aligned.

Rein statisch gesehen könnte die Schubplatte auch lediglich gleich lang wie die Dicke der Isolationsplatte entsprechend sein. Bei der hier gewählten Ausführungsform ragt die Schubplatte jedoch beidseitig aus dem Isolationskörper 2 hinaus und im eingebauten Zustand ragt nun der entsprechende Überstand 5 in der angrenzenden Kragplatte 20 einerseits und in die angrenzende Bodendeckenkante andererseits hinein. Hierdurch wird erreicht, dass der geschweisste Bereich vollständig vom Beton überdeckt ist und somit nicht der Umwelt ausgesetzt wird. Dies ist bei Lösungen bei denen entsprechende Zugstäbe und Druckstäbe, die an den Oberkanten beziehungsweise Unterkanten der Schubplatten angeschweisst sind, nicht realisierbar.Purely statically speaking, the thrust plate could only be the same length as the thickness of the insulating plate be. In the embodiment selected here, however, the thrust plate protrudes on both sides of the insulating body 2 and in the installed state now protrudes the corresponding supernatant 5 in the adjacent cantilever plate 20 on the one hand and in the adjacent Bodendeckenkante the other. This ensures that the welded area is completely covered by the concrete and thus is not exposed to the environment. This is not feasible in solutions in which corresponding tension rods and pressure rods, which are welded to the upper edges or lower edges of the thrust plates, not feasible.

Ein weiterer Vorteil der erfindungsgemässen Lösung besteht auch darin, dass den Fugenspaltqueren lediglich die Schubplatten verbleiben und nicht noch zusätzlich die Zug- und Druckstäbe diesen Fugenspalt queren wobei entsprechend die Wärmeleitung minimiert wird.Another advantage of the inventive solution is also that the joint gap traverses remain only the thrust plates and not additionally traverse the tension and compression rods this joint gap and accordingly the heat conduction is minimized.

Die U-förmigen Bügel bilden selbstverständlich statisch gesehen wiederum Zugstäbe und Druckstäbe. Die Kräfte verlaufen als geschlossenes System direkt durch die Schubplatte hindurch. Über die Schubplatten wird zusätzlich auch die Querkraft übertragen. Gesonderte diagonal verlaufende Querkraftstäbe sind nicht erforderlich. Dank der symmetrischen Gestaltung des erfindungsgemässen Kragplattenanschlusselementes ist dieses bezüglich dem Einbau nicht mehr richtungsgebunden.Of course, the U-shaped stirrups again form tension rods and pressure rods in static terms. The forces run as a closed system directly through the thrust plate. In addition, the transverse force is transmitted via the thrust plates. Separate diagonal transverse force bars are not required. Thanks to the symmetrical design of the inventive Kragplattenanschlusselementes this is with respect to the installation no directional.
