Abstract

The connector has a rectangular insulating body (11) through which reinforcement bars pass. These bars are in pairs one above the other, and are secured either side of the body in end plates (12) made from a rustproof material. The bars nearest the floor plate are divided into sections (13), and are parted off at the side of one end plates furthest from the joint seam (7), where they have screwed ends to engage anchors. The bars can be enclosed in rustproof sleeves (131) which pass through the end plates, with the space between the bars and sleeves being filled with a hardening material to form a core. The bars may be steel bars as used in building work, with screwed ends protruding from the sleeves.

Description

Die vorliegende Erfindung betrifft ein Kragplattenanschlusselement zum isolierten, kraftschlüssigen Verbinden einer Bodendeckenplatte mit einer auskragenden Platte mit einem quaderförmigen Isolationskörper und diesen durchsetzenden Armierungsstäben, die jeweils zu zweien vertikal übereinander je beidseitig des Isolationskörpers in Stirnplatten aus korrosionsbeständigem Material gehalten sind.The present invention relates to a cantilever panel connection element for the isolated, non-positive connection of a floor cover plate with a cantilevered plate with a cuboid insulating body and this passing through reinforcing rods, which are held vertically to each other vertically on each side of the insulating body in face plates made of corrosion-resistant material.

Ein Kragplattenanschlusselement der eingangs genannten Art ist aus der EP-B-0 338 972 (Bau-Box Ewiag) bekannt. Es handelt sich hierbei um ein Bauelement, das insbesondere zur Verbindung einer Bodendeckenplatte und einer Balkonplatte eingesetzt wird. Dieses, heute der Anmelderin gehörende, Schutzrecht hat erstmals ein im Fugenbereich korrosionsgeschütztes Kragplattenanschlusselement geschaffen, das zudem dank Stirnplatten die Betonerosion durch den Einfluss der Wechselbelastungen vermeidet. Das Element war entweder vollständig aus rostfreiem Stahl gefertigt oder wies Hülsen aus rostfreiem Stahl auf, die die den Fugenspalt überbrückenden und den Isolationskörper durchsetzenden Armierungsstäbe schützend umgeben, wobei der Zwischenraum zwischen den Hülsen und den Armierungsstäben mit einem härtenden Material ausgegossen ist.A cantilever connection element of the aforementioned type is known from EP-B-0 338 972 (Bau-Box Ewiag). This is a component that is used in particular for connecting a floor ceiling panel and a balcony slab. This protective right, which belongs to the applicant today, has for the first time created a cantilevered connection element protected against corrosion in the joint area, which, in addition, avoids concrete erosion due to the influence of the alternating loads thanks to faceplates. The element was either entirely made of stainless steel or stainless steel sleeves which protectively surround the reinforcing bars bridging the joint gap and passing through the insulator body, the space between the sleeves and the reinforcing bars being filled with a hardening material.

Aus der CH 678 076 ist ein isolationselement für kragplattenauschlüsse bekannt, das aus einem Körper aus isolierenden Material und mindestens eines Hülseneinheit, enthaltend mindestens zwei parallele gleichlange, den Körper durchdringende stahlhülsen zur Aufnahme von Armierungsstählen, besteht. Auf der Kragplattenseite ist eine kupplung mit Gewinde zur Aufnahme eines Auschlussarmierung vorgesehen.From CH 678 076 an insulation element for cantilever plate exclusions is known, which consists of a body made of insulating material and at least one sleeve unit containing at least two parallel equal length, the body penetrating steel sleeves for receiving reinforcing steels. On the cantilever plate side a threaded coupling is provided for receiving a Auschlussarmierung.

Weitere Kragplattenanschlusselemente verschiedenster Bauart sind bekannt. Rein beispielsweise wird hier auf die Dokumente DE-A-31 16 381, EP-A-0 119 165 oder DE-A-34 46 006 verwiesen, wobei letztere Variante neben Druck- und Zugstäben auch noch Querstäbe aufweist, die im Fugenbereich mit korrosionsbeständigen Manschetten versehen sind.Other Kragplattenanschlusselemente various types are known. For example, reference is made here to the documents DE-A-31 16 381, EP-A-0 119 165 or DE-A-34 46 006, the latter variant, in addition to pressure and tension rods, also having cross bars which are corrosion-resistant in the joint area Cuffs are provided.

Daneben ist aus der DE-A-4 427 962 eine vorrichtung zur statisch tragenden, korrosionsgeschützten, thermisch gedämmten verbindung zweier Baukörper bekannt, bei der die Tragelemente an ihren beiden Enden mit Muffen versehen sind, an die Bewehrung des anliegenden Bauteile schließbar ist.In addition, from DE-A-4 427 962 a device for statically supporting, corrosion-protected, thermally insulated connection of two structures known in which the support members are provided at both ends with sleeves, can be closed to the reinforcement of the adjacent components.

Alle bekannten Varianten sind Lösungen, die für den Ortsbetonbau konzipiert sind. Zwar lassen sich diese Kragplattenanschlusselemente allesamt auch verwenden bei vorfabrizierten Kragplatten, beispielsweise Balkonplatten, doch verlangt dies oftmals speziell dimensionierte Elemente oder die Armierungsstäbe des Kragplattenanschlusselementes müssen mühsam angepasst werden.All known variants are solutions that are designed for local concrete construction. Although these cantilever panel connection elements can all also be used in prefabricated cantilever panels, for example balcony panels, this often requires specially dimensioned elements or the reinforcing rods of the cantilever panel connection element must be tediously adjusted.

Ferner ragen jene Armierungsstäbe des Kragplattenanschlusselementes, welche zum Einbau der in Ortsbetonbauweise zu erstellenden Bodendeckenplatten dienen, weit aus dem Fertigbetonteil heraus und sind ungeschützt. Entsprechend ist die Gefahr gross, dass diese Armierungsstäbe vor dem Einbau beim Transport oder bei der Lagerung sowie beim Einbau und dem Handling verbogen werden.Furthermore, those reinforcing bars of the cantilevered connection element, which serve for the installation of the ground concrete slabs to be produced in the method of local concrete, protrude far out of the precast concrete part and are unprotected. Accordingly, there is a great risk that these reinforcing bars are bent before installation during transport or storage, as well as during installation and handling.

Ein weiteres Problem ist, dass für verschiedene Kragplatten verschiedene relativ sperrige Kragplattenanschlusselemente an Lager gelegt werden mussten. Auch der Platzbedarf für die Lagerung und den Transport der fertigen Kragplatten war entsprechend enorm.Another problem is that different relatively bulky cantilever panel connection elements had to be stored for different cantilevers. The space required for the storage and transport of the finished cantilever plates was correspondingly enormous.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Kragplattenanschlusselement der eingangs genannten Art zu schaffen, welches besonders für die Herstellung von vorfabrizierten Kragplatten geeignet ist und die vorgenannten Nachteile meidet.It is therefore an object of the present invention to provide a cantilever connection element of the type mentioned, which is particularly suitable for the production of prefabricated cantilever plates and avoids the aforementioned disadvantages.

Diese Aufgabe löst ein Kragplattenanschlusselement mit den Merkmalen des Patentanspruchs 1.This object is achieved by a cantilever panel connection element having the features of patent claim 1.

Die beidseits mit Gewinden versehenen Armierungsstababschnitte eigeben ein universales Kragplattenanschlusselement, an dem beidseits anwendungsspezifische Verankerungselemente anschraubbar sind.The reinforcing bar sections provided with threads on both sides provide a universal cantilevered connection element to which application-specific anchoring elements can be screwed on both sides.

Weitere erfindungsgemässe Ausgestaltungsformen gehen aus den abhängigen Patentansprüchen hervor.Further inventive embodiments will become apparent from the dependent claims.

Die Verwendung des gesamthaft mit der Bezugszahl 10 bezeichneten Kragplattenanschlusselementes ist in der Figur 1 dargestellt. In der Figur links erkennt man die Kragplatte 1 und rechts die Bodendeckenplatte 2. Die Aussenwand ist mit 3 bezeichnet. Diese ist mit einer Aussenisolation 4 versehen, auf der ein Verputz 5 aufgebracht ist. Zwischen der Kragplatte 1 und der Bodendeckenplatte 2 verbleibt somit eine Fuge 7. Sowohl auf der Kragplatte 1 als auch auf der Bodendeckenplatte 2 ist eine Deckschicht 6, ein sogenannter Estrich aufgebracht. In der mit der Aussenisolation 4 fluchtenden Fuge 7 kommt der Isolationskörper 11 des Kragplattenanschlusselementes 10 zu liegen. Hierdurch wird eine optimale Wärmedämmung erreicht, so dass die Außentemperatur der Kragplatte 1 sich nicht auf die Bodendeckenplatte 2 überträgt.The use of the Kragplattenanschlusselementes generally designated by the reference numeral 10 is shown in the figure 1. In the figure on the left you can see the cantilever 1 and right the ground cover plate 2. The outer wall is denoted by 3. This is provided with an external insulation 4, on which a plaster 5 is applied. Thus, a joint 7 remains between the cantilever plate 1 and the bottom cover plate 2. Both on the cantilever plate 1 and on the bottom cover plate 2, a cover layer 6, a so-called screed, is applied. In the aligned with the outer insulation 4 joint 7 of the insulation body 11 of the cantilever panel connection element 10 comes to rest. As a result, an optimal thermal insulation is achieved, so that the outside temperature of the cantilever 1 does not transfer to the bottom cover plate 2.

Das Kragplattenanschlusselement 10 besteht im wesentlichen aus einem Isolationskörper 11, der zwischen zwei Stirnplatten 12 angeordnet ist. Der Isolationskörper 11 kann prinzipiell aus einem beliebigen Isolationsmaterial gefertigt sein. Dies ist entweder ein geschäumter Kunststoff oder bevorzugterweise ein Körper aus einer Mineralfaserplatte. Die beiden Stirnplatten 12 sind aus rostfreiem Stahl gefertigt und liegen im eingebauten Zustand in der Stirnfläche der Kragplatte 1, respektive in der Stirnfläche der Bodendeckenplatte 2. Beide Stirnplatten 12, die sich in der Fugenlängsrichtung erstrecken, werden von einer Vielzahl von Armierungsstababschnitten 13 durchsetzt. Diese Armierungsstababschnitte 13 sind entweder gerade verlaufende Armierungsstababschnitte 13', wenn es sich dabei um Abschnitte von Zug- oder Druckstäben handelt, oder zweifach gebogene Armierungsstababschnitte 13'', wenn es sich hierbei um Abschnitte von Querkraftstäben handelt. Prinzipiell sind jeweils zwei gerade verlaufende Armierungsstababschnitte 13' paarweise vertikal übereinander angeordnet. Die der Querkraftübertragung dienenden Armierungsstababschnitte 13" verlaufen im Fugenbereich schräg von unten nach oben. Die Armierungsstababschnitte 13 enden kurz nach dem Durchtritt durch die Stirnplatte 12, zumindest bodendeckenplattenseitig in Schraubgewinden 14. Erfindungsgemäß enden die Armierungsstababschnitte 13 aber auch kragplattenseitig in Gewinden 14.The Kragplattenanschlusselement 10 essentially consists of an insulating body 11 which is arranged between two end plates 12. The insulating body 11 can in principle be made of any insulating material. This is either a foamed plastic or preferably a body of mineral fiber board. The two end plates 12 are made of stainless steel and are in the installed state in the end face of the cantilever 1, respectively in the end face of the bottom cover plate 2. Both end plates 12, which extend in the longitudinal direction of the joint, are penetrated by a plurality of Armierungsstababschnitten 13. These Armierungsstababschnitte 13 are either straight Armierungsstababschnitte 13 ', if these are sections of tension or compression bars, or doubly curved Armstabstababschnitte 13' ', if these are sections of transverse force bars. In principle, two straight reinforcing bar sections 13 'are arranged vertically one above the other in pairs. The reinforcement rod sections 13 terminate shortly after passing through the end plate 12, at least on the bottom cover plate side in screw threads 14. According to the invention, the reinforcing rod sections 13 also terminate in threads 14 on the faceplate side.

Gemäß Figur 1 sind die Zug- und Druckstäbe 13', die in der Kragplatte 1 liegen, einstückig mit den Armierungsstababschnitten 13 verbunden. Hierbei wird man vorzugsweise die Zug- oder Druckstäbe 13' aus handelsüblichem Baustahl fertigen. Diese Zug- oder Druckstäbe 13' durchsetzen die beiden Stirnplatten 12 und bilden somit gleichzeitig die Armierungsstababschnitte 13. In jenem Bereich, in dem sie die Armierungsstababschnitte 13 bilden, sind sie mit einer Hülse 132 umgeben. Ihr bodendeckenplattenseitiges Ende, welches aus den Hülsen 132 herausragt, ist mit einem Schraubgewinde 14 versehen. Die die Armierungsstababschnitte 13 durchsetzenden Teile der Zug- oder Druckstäbe 13' bilden somit den Kern der Armierungsstababschnitte 13. Erst kurz vor der Erstellung der Bodendeckenplatte 2 werden auf den Gewinden 14 die entsprechenden Verankerungselemente 15 aufgeschraubt. Im dargestellten Beispiel handelt es sich dabei um Zugstäbe 15' beziehungsweise Druckstäbe 15", die jeweils mit entsprechenden Schraubkupplungsteilen 16 ausgerüstet sind. Solche Armierungsstäbe mit Schraubkupplungsteilen 16 sind übliche Handelsware. Sie werden bisher zur Erstellung von überlangen Armierungsstäben eingesetzt.According to Figure 1, the tension and compression bars 13 ', which are in the cantilever 1, in one piece connected to the Armierungsstababschnitten 13. In this case, it is preferable to manufacture the tension or compression rods 13 'from commercially available structural steel. These tension or compression bars 13 'pass through the two end plates 12 and thus simultaneously form the Armierungsstababschnitte 13. In that area in which they form the Armierungsstababschnitte 13, they are surrounded by a sleeve 132. Your bottom cover plate side end, which protrudes from the sleeves 132 is provided with a screw thread 14. The Armierungsstababschnitte 13 passing through parts of the tension or compression bars 13 'thus form the core of Armierungsstababschnitte 13. Only shortly before the creation of the ground cover plate 2, the corresponding anchoring elements 15 are screwed onto the threads 14. In the example shown, these are tension rods 15 'or pressure rods 15 ", which are each equipped with corresponding threaded coupling parts 16. Such reinforcing rods with threaded coupling parts 16 are common commercial goods.

Prinzipiell wäre es möglich, das gesamte Kragplattenanschlusselement 10 mit den Armierungsstababschnitten 13 und den Zug- oder Druckstäben 13' vollständig auch aus rostfreiem Stahl zu fertigen. Dies lassen jedoch die Bauvorschriften in verschiedenen Ländern nicht zu. Auch aus Kostengründen wird man diese Lösung eher meiden. Die hier beschriebene Lösung, bei der nur die Stirnplatten und die Hülsen 132, die die Armierungsstababschnitte 13 ummanteln, aus rostfreiem Stahl gefertigt sind, ist erheblich kostengünstiger und daher bevorzugt.In principle, it would be possible to completely manufacture the entire cantilever connection element 10 with the reinforcing bar sections 13 and the tension or compression bars 13 'also from stainless steel. However, this does not allow the building codes in different countries. Also for cost reasons, one will rather avoid this solution. The solution described here, in which only the end plates and the sleeves 132 which encase the Armierungsstababschnitte 13 are made of stainless steel, is considerably cheaper and therefore preferred.

In der Figur 2 ist eine Variante des erfindungsgemässen Kragplattenanschlusselementes 10 dargestellt. Es zeigt einen Vertikalschnitt senkrecht zur Verlaufsrichtung der Fuge 7 im Bereich zweier senkrecht übereinander liegender, gerader Armierungsstababschnitte 13, die zur Zug- oder Druckkraftübertragung dienen. Man erkennt die beidseitig angeordneten Stirnplatten 12, zwischen denen der Isolationskörper 11 angeordnet ist. Der Isolationskörper 11 wird durch Armierungsstababschnitte 13 durchsetzt. Beidseitig sind an der der Fuge 7 abgelegenen Seiten der Stirnplatten 12 an den Armierungsstababschnitten 13 Schraubgewinde 14 angebracht. Hier erkennt man deutlich den Aufbau der Armierungsstababschnitte 13. Sie bestehen aus einem Kern 131, der länger ist als die sie umgebende Hülse 132. Die Hülse ist wiederum aus einem nichtkorrodierendem Material, vorzugsweise aus rostfreiem Stahl, gefertigt. Der Zwischenraum zwischen dem Kern 131 und der Hülse 132 ist durch ein härtendes Material 133, vorzugsweise ein Harz, ausgefüllt. Der Kern 131 ragt auf beiden Seiten aus der Hülse 132 heraus und ist mit den genannten Schraubgewinden 14 versehen. Auf die Schraubgewinde 14 können verschiedenartig ausgebildete Verankerungselemente 15 aufgeschraubt werden. Dies können entweder Zugstäbe 15', Druckstäbe 15'' oder Druckplatten 15"' sein. Bei den Druckplatten handelt es sich um einfache Stahlplatten, die mit einem Durchgangsloch mit Innengewinde 16 versehen sind. Die hier dargestellte Ausführungsform ist besonders bevorzugt, da sie alle Optionen für die weitere Verwendung offenlässt. Entsprechend können solche Elemente in grosser Stückzahl gefertigt werden und entsprechend den Bedürfnissen mit angepassten Verankerungselementen 15 komplementiert werden. Je nach den auftretenden Kräften genügt es, wenn die Kragplattenanschlusselemente 10 lediglich gerade verlaufende Armierungsstababschnitte 13 für den Anschluss von Zug- oder Druckstäben aufweisen. Sind jedoch die zu erwartenden Querkräfte relativ gross, so wird man in der Fugenlängsrichtung versetzt zwischen zwei benachbarten zug- bzw. druckbelasteten Armierungsstababschnitten 13' jeweils einen gebogen verlaufenden Armierungsstababschnitt 13" zur Übertragung der Querkräfte vorsehen. Ein solcher Armierungsstababschnitt 13" zur Übertragung der Querkräfte ist in der Figur 3 dargestellt. Dieser weist ansonsten denselben Aufbau auf, wie er anhand der Figur 2 beschrieben ist.FIG. 2 shows a variant of the cantilever panel connection element 10 according to the invention. It shows a vertical section perpendicular to the direction of the joint 7 in the region of two vertically superimposed, straight Armierungsstababschnitte 13, which serve for tensile or compressive force transmission. It can be seen on both sides arranged end plates 12, between which the insulation body 11 is arranged. The insulating body 11 is penetrated by Armierungsstababschnitte 13. On both sides of the joint 7 remote sides of the end plates 12 are attached to the Armierungsstababschnitten 13 screw 14. It consists of a core 131, which is longer than the surrounding sleeve 132. The sleeve is again made of a non-corrosive material, preferably made of stainless steel. The space between the core 131 and the sleeve 132 is filled by a hardening material 133, preferably a resin. The core 131 protrudes on both sides out of the sleeve 132 and is provided with said screw threads 14. On the screw thread 14 variously shaped anchoring elements 15 can be screwed. These can be either tension bars 15 ', pressure bars 15 "or pressure plates 15"' Printing plates are simple steel plates, which are provided with a through hole with internal thread 16. The embodiment shown here is particularly preferred because it leaves all options open for further use. Accordingly, such elements can be manufactured in large numbers and be complemented according to the needs with adapted anchoring elements 15. Depending on the forces occurring, it is sufficient if the cantilever panel connection elements 10 have only straight reinforcing bar sections 13 for the connection of tension or compression bars. If, however, the transverse forces to be expected are relatively large, then in the longitudinal direction of the joint between two adjacent tensioned or pressure-loaded reinforcing bar sections 13 'a curved reinforcing bar section 13 "will be provided for the transmission of the transverse forces shown in the figure 3. This otherwise has the same structure as described with reference to FIG 2.

Die Vorteile bezüglich der Verwendung, dem Transport, der Lagerung und dem Einbau sowie insbesondere bei der Erstellung von Fertigbetonkragplatten ist offensichtlich.The benefits in terms of use, transportation, storage and installation, and in particular in the preparation of precast cantilever panels is obvious.
