Description

Die vorliegende Erfindung betrifft ein Kragplattenanschlusselement zum isolierten, kraftschlüssigen Verbinden mit einer auskragenden Platte, mit einem quaderförmigen Isolationskörper und diesen durchsetzenden Armierungsstäben.The present invention relates to a cantilever plate connecting element for insulated, non-positive connection with a cantilever plate, with a cuboid-shaped insulation body and reinforcing bars passing through it.

Bis anhin gab es zwei Möglichkeiten, einen Kragplattenanschluss zu erstellen, nämlich erstens, eine Betonplatte ununterbrochen vom aufliegenden Teil zum auskragenden Teil durchzuziehen oder zweitens, die Betonplatte zwischen aufliegendem Teil und aussenliegendem Teil zu trennen. Im ersten Fall ergeben sich grosse Temperaturunterschiede in den innen- und aussenliegenden Teilen, welche zu Rissbildungen im Beton führen. Die Armierung kann bei Eintreten des Wassers in die Risse durch Rostbildung beschädigt oder sogar zerstört werden. Dies bedingt jeweils aufwendige Sanierungsmassnahmen. Wird die Armierungsbeschädigung zu spät entdeckt, so kann der Verlust der Tragfähigkeit bis zum Bruch der Kragplatte führen. Im zweiten Fall werden mittels Kragplattenanschlusselementen die entsprechende, isolierte Verbindung hergestellt.Up to now, there were two options for creating a cantilever slab connection: firstly, continuously pulling a concrete slab from the overlying part to the cantilevered part, or secondly, separating the concrete slab between the overlying part and the external part. In the first case, there are large temperature differences in the inner and outer parts, which lead to crack formation in the concrete. If the water enters the cracks, the reinforcement can be damaged by rust formation or even destroyed. This requires time-consuming renovation measures. If the reinforcement damage is discovered too late, the loss of the load-bearing capacity can lead to the cantilever plate breaking. In the second case, the corresponding, insulated connection is made using cantilever plate connection elements.

Aus der EP-A 034 332 ist ein Kragplattenanschlusselement mit einem lsolationskörper und diesen durchsetzenden Armierungsorganen bekannt. Unter Einwirkung der Schwerkraft auf die Kragplatte entsteht ein Drehmoment, welches bekanntlich durch zwei parallele entgegengesetzte Kräfte verursacht wird. Diese Kräfte werden im Kragplattenanschlusselement gemäss der EP-A 034 332, einerseits durch gestreckte Armierungseisen für die Zugkräfte, andererseits durch Druckelemente im Isolationskörper für die entgegengesetzten Druckkräfte, aufgenommen und auf den Baukörper übertragen.EP-A 034 332 discloses a cantilever plate connection element with an insulation body and reinforcing members passing through it. Under the influence of gravity on the cantilever plate, a torque is created, which is known to be caused by two parallel opposite forces. These forces are absorbed in the cantilever plate connection element according to EP-A 034 332, on the one hand by stretched reinforcement bars for the tensile forces, on the other hand by pressure elements in the insulation body for the opposite pressure forces, and transmitted to the structure.

Die Verwendung von Druckelementen und Zugstäben, die beide den druckfesten Isolationskörper durchsetzen, ist herstellungstechnisch relativ aufwendig. Das gesamte Kragplattenanschlusselement ist zudem relativ sperrig und unstabil. Obwohl das genannte Kragplattenanschlusselement relativ aufwendig ist, ist es statisch nicht optimal gestaltet.The use of pressure elements and tension rods, both of which pass through the pressure-resistant insulation body, is relatively complex to manufacture. The entire cantilever panel connection element is also relatively bulky and unstable. Although the cantilever plate connection element mentioned is relatively complex, it is structurally not optimally designed.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Kragplattenanschlusselement zu schaffen, welches die vorgenannten Nachteile behebt.It is therefore the object of the present invention to provide a cantilever plate connection element which overcomes the aforementioned disadvantages.

Diese Aufgabe löst ein Kragplattenanschlusselementdereingangs genannten Art mit den Merkmalen des Patentanspruches 1. Die Gestaltung der Armierungsstäbe in Form von vertikal verlaufenden Schlaufen ermöglicht es durch dasselbe Organ sowohl die Zug-, wie die Druckkräfte aufzunehmen. Das gesamte Element ist besser zu handhaben, da die Schlaufen untereinander durch Querstäbe verbunden sind.This problem is solved by a cantilever plate connecting element of the type mentioned at the beginning with the features of claim 1. The design of the reinforcing bars in the form of vertically extending loops enables the same organ to absorb both the tensile and compressive forces. The entire element is easier to handle because the loops are connected to each other by cross bars.

Im weiteren bezieht sich die Erfindung auf eine Verwendung des Kragplattenanschlusselementes zur Verbindung einer Wohndecke mit einer Balkonbodenplatte. Bevorzugte Ausführungsbeispiele der Erfindung ergeben sich aus den abhängigen Ansprüchen.Furthermore, the invention relates to a use of the cantilever panel connection element for connecting a living ceiling to a balcony floor panel. Preferred embodiments of the invention result from the dependent claims.

Im folgenden wird anhand der beiliegenden Zeichnung ein Ausführungsbeispiel der Erfindung näher beschrieben.In the following an embodiment of the invention will be described with reference to the accompanying drawings.

Das Kragplattenanschlusselement 1 gemäss Fig. 1 umfasst einen quaderförmigen Isolationskörper 2 sowie senkrecht zu zwei seiner Aussenflächen in gleichen Abständen parallel angeordnete schlaufenförmige Armierungsstäbe 3, 4, 5 und 6. Auf beiden Seiten des Isolationskörpers sind oben und unten innerhalb der schlaufenförmigen Armierungsstäbe 3, 4, 5 und 6 untereinander parallel und parellel zu den obengenannten Aussenflächen des Isolationskörpers 2 angeordnete obere Querstäbe 7, 8, 9 und 10 sowie untere Querstäbe 11,12,13 und 14 vorgesehen. Die schlaufenförmigen Armierungsstäbe 3, 4, 5 und 6 sind vorzugsweise aus verzinktem Stahl III oder aus rostfreiem Stahl mit einem Durchmesser von 14 mm oder 16 mm hergestellt. Die Querstäbe 7 bis 14 sind vorzugsweise aus Stahl III mit einem Durchmesser von 6 mm gefertigt. Der Isolationskörper 2 ist vorzugsweise aus wasserabstossender Steinwolle gefertigt und damit auch brandsicher. Vorzugsweise weisen die Armierungsstäbe 3 bis 6 untereinander einen Abstand von ca. 25 cm auf. Die Querstäbe werden mit den Armierungsstäben verschweisst und an den Stabenden zum Schutz gegen Verletzungsgefahr mit nichtdargestellten Plastikhütchen versehen. Der Isolationskörper kann für einen besseren Schutz gegen Wasser oder Dampf auch mit einer nichtdargestellten Schutzfolie ganz oder teilweise eingepackt werden. An den äusseren Armierungsstäben 3 und 6 des Kragplattenanschlusselementes 1 sind am unteren Teil je zwei äussere, winkelförmige Distanzhalter 15, 16, 17 und 18 sowie je zwei innere, radförmige Distanzhalter 19, 20, 21 und 22 vorgesehen.1 comprises a cuboid-shaped insulation body 2 as well as loop-shaped reinforcement bars 3, 4, 5 and 6 arranged in parallel at equal intervals perpendicular to two of its outer surfaces. On both sides of the insulation body, the loop-shaped reinforcement bars 3, 4, 5 and 6 mutually parallel and parallel to the above-mentioned outer surfaces of the insulating body 2 arranged upper cross bars 7, 8, 9 and 10 and lower cross bars 11, 12, 13 and 14 are provided. The loop-shaped reinforcing bars 3, 4, 5 and 6 are preferably made of galvanized steel III or stainless steel with a diameter of 14 mm or 16 mm. The cross bars 7 to 14 are preferably made of steel III with a diameter of 6 mm. The insulation body 2 is preferably made of water-repellent rock wool and thus also fire-proof. The reinforcing bars 3 to 6 are preferably at a distance of approximately 25 cm from one another. The cross bars are welded to the reinforcement bars and provided with plastic hats (not shown) at the bar ends to protect against the risk of injury. For better protection against water or steam, the insulation body can also be packed in whole or in part with a protective film (not shown). On the outer reinforcing bars 3 and 6 of the cantilever plate connection element 1, two outer, angular spacers 15, 16, 17 and 18 and two inner, wheel-shaped spacers 19, 20, 21 and 22 are provided on the lower part.

In Fig. 2 ist das Kragplattenanschlusselement 1 in eingebautem Zustand zwischen einer vertikalen Hausinnenwand 23 und einer vertikalen Hausaussenwand 24 dargestellt. Eine linke Schlaufe 25 des Armierungselementes 3 erstreckt sich in eine Balkonbodenplatte 26 und eine rechte Schlaufe 27 des Armierungselementes 3 in eine Wohnungsdecke 28. Ein Netz aus Armierungsstäben 29 und 30 in der Balkonplatte ist mit dem linken Teil 25 der Armierungsstäbe des Kragplatteanschlusselementes verbunden. Oberhalb und unterhalb des Isolationskörpers 2 gemäss Fig. 2 erstreckt sich die Isolation zwischen der Hausinnenwand 23 und der Hausaussenwand 24 in vertikaler Richtung nach unten und oben weiter. Zwischen der Balkonplatte 26 und der Hausaussenwand 24 kann unterhalb der Balkonplatte eine Trennmatte 32 vorgesehen sein. Um ein Benetzen oder ein Verschmutzen der Isolation unterhalb des Kragplattenanschlusselementes, d.h. im bestehenden Mauerwerk zu vermeiden, kann im unteren Bereich des Isolationskörpers 2 beidseits ein Füllschaumstoff 33 zur sauberen Abtrennung zwischen Betondecke und Isolation angebracht werden. Die Länge der Armierungsstäbe wird so gewählt, dass die Kraftübertragung auf das Armierungsnetz 29, 30 und die Platte 26 gewährleistet ist und die erforderliche Verankerungslänge eingehalten wird.2 shows the cantilever plate connecting element 1 in the installed state between a vertical house inner wall 23 and a vertical house outer wall 24. A left loop 25 of the reinforcement element 3 extends into a balcony floor slab 26 and a right loop 27 of the reinforcement element 3 into a ceiling 28. A network of reinforcement bars 29 and 30 in the balcony slab is connected to the left part 25 of the reinforcement bars of the cantilever plate connection element. Above and below the insulation body 2 according to FIG. 2, the insulation between the inside wall 23 and the outside wall 24 extends vertically downwards and upwards. A separating mat 32 can be provided between the balcony plate 26 and the outside wall 24 of the house below the balcony plate. In order to avoid wetting or soiling of the insulation beneath the cantilever panel connection element, ie in the existing masonry, a fill can be provided on both sides in the lower region of the insulation body 2 Foam 33 for clean separation between the concrete ceiling and insulation are attached. The length of the reinforcement bars is chosen so that the force transmission to the reinforcement net 29, 30 and the plate 26 is ensured and the required anchoring length is maintained.

In Fig. 3 ist ein Ausschnitt des Kragplattenelementes 1 in vergrössertem Massstab dargestellt. Dabei ist der gemäss Fig. 2 in die Balkonbodenplatte hineinragende Teil 25 des vordersten Armierungsstabes mit den Distanzhaltern 15 und 19 dargestellt. Der äussere Distanzhalter 15 ist zwischen den Querstäben 11 und 12 und der innere Distanzhalter zwischen dem Querstab 12 und dem Isolationskörper im unteren Teil der Armierungsschlaufe 3 angebracht.3 shows a detail of the cantilever plate element 1 on an enlarged scale. The part 25 of the foremost reinforcing bar projecting into the balcony floor slab according to FIG. 2 is shown with the spacers 15 and 19. The outer spacer 15 is mounted between the cross bars 11 and 12 and the inner spacer between the cross bar 12 and the insulation body in the lower part of the armoring loop 3.

Gemäss Fig. 4 besteht der äussere Distanzhalter 15 aus einem mit dem Armierungsstab 3 verschweissten Winkeleisen mit zwei Schenkeln 34und 35, wobei im unteren Schenkel 35 ein Loch zum Einschlagen eines Nagels in die Holzverschalung unterhalb der Betondecke vorgesehen ist. Auf dem unteren Schenkel 35 wird vorzugsweise ein nichtdargestellter Kunststoffhut aufgesetzt.4, the outer spacer 15 consists of an angle iron welded to the reinforcing rod 3 with two legs 34 and 35, a hole being provided in the lower leg 35 for driving a nail into the wooden casing below the concrete ceiling. A plastic hat (not shown) is preferably placed on the lower leg 35.

Der innere Distanzhalter 19 gemäss Fig. 5 ist vorzugsweise aus Kunststoff in der Form eines Naben 37 aufweisenden Rades dargestellt. Durch einen Schlitz 38 kann der Distanzhalter 19 auf den Armierungsstab 3 aufgesetzt werden.The inner spacer 19 according to FIG. 5 is preferably made of plastic in the form of a wheel 37 having hubs. The spacer 19 can be placed on the reinforcing bar 3 through a slot 38.

Mit Hilfe des beschriebenen Kragplattenanschlusselementes kann eine einwandfreie Wärmeisolation erzielt werden, was sich auf eine K-Wert-Verbesserung gegenüber konventionellen Methoden auswirkt. Die häufig auftretenden grauen bis schwarzen Verfärbungen an den Deckenrändern im Wohnbereich entstehen nicht mehr, da durch die korrekt isolierte Trennung eine Wärmebrücke vermieden wird. Im weiteren besteht ein Vorteil darin, dass keine zusätzliche Stützkonstruktion erstellt werden muss. Der Isolationskörper des Kragplattenanschlusselementes dient beim Bauvorgang gleichzeitig als Abschalung. Die Kragplatte kann also, wenn dies für den Baufortschritt einen Vorteil bringt, nachträglich erstellt werden, ohne dass dadurch zusätzliche Arbeit entstehen würde. Mit den Armierungsstäben des Kragplattenanschlusselementes wird das grösste auftretende Moment in der Kragplatte aufgenommen. Da das Moment vom Auflagepunkt aus sehr rasch kleiner wird, ist das massgebende Moment für die Armierung des Kragplattenanschlusselementes wesentlich kleiner. Das bedeutet, dass sich im Normalfall eine bemerkenswerte Armierungsaussparung ergibt. Durch das Verwenden eines brandsicheren Isolationsmaterials für das Isolationselement kann ohne weiteres ein Feuerschutz F 90 gemäss den öffentlichen Brandschutzvorschriften erreicht werden.With the aid of the cantilever plate connection element described, perfect thermal insulation can be achieved, which has an effect on an improvement in the K value compared with conventional methods. The frequently occurring gray to black discolourations on the edges of the ceiling in the living area no longer occur, since the correctly insulated separation prevents a thermal bridge. Another advantage is that no additional support structure has to be created. The insulation body of the cantilever panel connection element also serves as formwork during the construction process. The cantilever plate can therefore, if this brings an advantage for the progress of the construction, be created without additional work. The greatest moment that occurs in the cantilever plate is absorbed with the reinforcing bars of the cantilever plate connecting element. Since the moment from the point of contact decreases very quickly, the decisive moment for the reinforcement of the cantilever plate connection element is considerably smaller. This means that there is normally a remarkable reinforcement recess. By using a fire-proof insulation material for the insulation element, fire protection F 90 in accordance with the public fire protection regulations can be achieved.

Bei korrektem Einbau des Kragplattenanschlusselementes sollten die Armierungsstäbe desselben nicht mit Wasser in Berührung kommen. Um jedoch ganz sicherzugehen, kann ein wasserabstossendes Material für den Isolationskörper 2 sowie rostfreier oder verzinkter Stahl für die Armierungsstäbe verwendet werden, um ein rostunanfälliges Element herzustellen. An der Stelle, wo die Armierungsstäbe durch den Isolationskörper hindurchtreten, kann auf dieselben Leim aufgetragen werden.If the cantilever plate connection element is installed correctly, the reinforcing bars of the same should not come into contact with water. However, to be on the safe side, a water-repellent material for the insulating body 2 and stainless or galvanized steel for the reinforcing bars can be used to produce a rust-resistant element. At the point where the reinforcing bars pass through the insulation body, glue can be applied to the same.

Ein weiterer Vorteil des Kragplattenanschlusselementes liegt darin, dass die Trittschallübertragung von der Kragplatte zur aufliegenden Platte, also z.B. von der Balkonbodenplatte zur Wohnungsdecke, wesentlich kleiner wird und somit eine Verbesserung des Wohnkomforts bewirkt.Another advantage of the cantilever panel connection element is that the impact sound transmission from the cantilever panel to the overlying panel, i.e. e.g. from the balcony floor slab to the ceiling, becomes much smaller and thus improves living comfort.

Ein weiterer Vorteil beim Einsatz der Kragplattenanschlusselemente liegt darin, dass die freie Wahl des günstigsten Zeitpunktes für die Erstellung der Kragplatte besteht, sowie ein rationelles Armieren erfolgen kann.Another advantage of using the cantilever panel connection elements is that there is a free choice of the cheapest time for the creation of the cantilever panel, as well as an efficient reinforcement.

Das Kragplattenanschlusselement kann auch für andere Zwecke, z.B. zur Verbindung von beliebigen Betonteilen verwendet werden. Ein nachträgliches «Ausbiegen» der Armierungsstäbe ist nicht erforderlich, was wiederum zur Folge hat, dass die Armierungsstäbe des Kragplattenanschlusselementes nicht unnötigen oder sogar Tragfähigkeitsverlust bewirkenden Störungen unterzogen werden.The cantilever plate connection element can also be used for other purposes, e.g. can be used to connect any concrete parts. Subsequent “bending out” of the reinforcing bars is not necessary, which in turn means that the reinforcing bars of the cantilever plate connection element are not subjected to unnecessary or even loss of load-bearing capacity.

In Fig. 6 ist ein Bügel 39 aus Armierungsstahl sowie dessen Anordnung an den Armierungsstäben des Kragplattenanschlusselementes dargestellt. Der Bügel wird in Form einer Schlaufe jeweils auf beiden Seiten des Isolationskörpers um den schlaufenförmigen Armierungsstab 3 gelegt und dient zur Übertragung der Querkraft. An jedem der vier schlaufenförmigen Armierungsstäbe 3-6 eines Kragplattenanschlusselementes 1 werden je zwei Bügel 39 angebracht.6 shows a bracket 39 made of reinforcing steel and its arrangement on the reinforcing bars of the cantilever plate connection element. The bracket is placed in the form of a loop on both sides of the insulation body around the loop-shaped reinforcing bar 3 and serves to transmit the transverse force. Two brackets 39 are attached to each of the four loop-shaped reinforcing bars 3-6 of a cantilever plate connecting element 1.

In Fig. 7 ist in schematischer Art ein Eckelement 40 dargestellt, welches z.B. bei Balkonen verwendet wird, welche auf zwei Seiten eines Hauses vorgesehen sind. Die vier schlaufenförmigen Armierungsstäbe 41 sind schiefwinklig zum Isolationskörper angeordnet. Die parallel zum Isolationskörper verlaufenden Querstäbe 42 sind ebenfalls durch strichpunktieerte Linien dargestellt.In Fig. 7 a corner element 40 is shown in a schematic manner, which e.g. is used for balconies, which are provided on two sides of a house. The four loop-shaped reinforcing bars 41 are arranged at an oblique angle to the insulation body. The cross bars 42 running parallel to the insulation body are also shown by dash-dotted lines.

Im eigentlichen Eckbereich verlaufen die Kräfte anders und die Anordnung der Armierungseisen entspricht daher nicht der patentgemässen Lehre.In the actual corner area, the forces run differently and the arrangement of the reinforcing bars therefore does not correspond to the patented teaching.

Falls die Armierungsstäbe der Kragplattenanschlusselemente aus normalem Armierungsstahl gefertigt sind, werden sie vorzugsweise im Bereich des Isolationselementes bis einige Zentimeter ausserhalb des Elementes mit Rostschutz überzogen. Beispielsweise können die Armierungsstäbe in einem ersten Schritt sandgestrahlt oder blankgebürstet werden. In einem zweiten Schritt können sie mit Rostschutz, beispielsweise Epoxi-Bleimenning, eventuell in mehreren Phasen, versehen werden. In einem dritten Schritt kann auf den Rostschutz Quarzsand aufgebracht werden.If the reinforcing bars of the cantilever plate connection elements are made of normal reinforcing steel, they are preferably coated with rust protection in the area of the insulation element up to a few centimeters outside the element. For example, the reinforcing bars can be sandblasted or brushed bright in a first step. In a second step, they can be provided with rust protection, for example epoxy lead lining, possibly in several phases. In a third step, quartz sand can be applied to the rust protection.

Die Armierungsstäbe können auch aus normalem Armierungsstahl und rostfreiem Stahl kombiniert werden. In diesem Falle ist der rostfreie Stahl im Bereich des Isolationskörpers bis einige Zentimeter ausserhalb desselben vorgesehen. Die übrigen Teile der Armierungsstäbe würden dann aus normalem Armierungsstahl gefertigt werden. In diesem Falle wäre kein Aufbringen eines Rostschutzes ntowendig.The reinforcing bars can also be combined from normal reinforcing steel and stainless steel. In this case, the stainless steel is provided in the area of the insulation body up to a few centimeters outside the same. The remaining parts of the reinforcing bars would then be made from normal reinforcing steel. In this case, it would not be necessary to apply rust protection.

Die Bügel 39 gemäss Fig. 6 können mit Distanzhaltern in Richtung des Isolationskörpers 2 versehen sein, damit derselbe sich vor dem Betonieren nicht relativ zu den Armierungsstäben verschieben kann.The brackets 39 according to FIG. 6 can be provided with spacers in the direction of the insulating body 2, so that the same cannot move relative to the reinforcing bars before concreting.
