Abstract

If concrete ceilings (1) are to be connected to walls (2) while maintaining between them expansion joints, dowels (4) have to be inserted. As the steel pins (5) and the bushings (6) have a round cross-section and as they can transmit without causing damages nothing but relatively small loads to the concrete surrounding them, the steel pins (5) as well as the bushings (6) are interconnected by junction plates (7, 8), thereby implying an increase of the bearing surfaces. Important loads may thereby be transmitted without damages to the concrete elements through a dowel (4). A front plate (9) connected to the sleeves (6) further facilitates the mounting of the dowel (4) in the cofferings by enabling its nailing to the latter.

Description

SCHUBDUEBEL PUSH DOWEL
Die vorliegende Erfindung betrifft einen Schubdübel, insbe¬ sondere für das Verbinden von Betondecken unter sich und mit Betonwänden, derart, dass zwischen den einzelnen Deckenele- raenten oder der Decke und der Wand eine Dilatationsfuge ver- bleibt.The present invention relates to a push dowel, in particular for connecting concrete ceilings to themselves and to concrete walls, in such a way that a dilatation joint remains between the individual ceiling elements or the ceiling and the wall.
Bei Bauwerken mit Wänden und Decken stellt sich immer das Pro¬ blem, die Decken derart zwischen oder auf die Wände zu legen, dass durch die natürliche Dilatation keine Schäden entstehen. Herkömmlicherweise ist dies derart geschehen, dass man die Decke in jeder Richtung zumindest einseitig auf Auflegern ab¬ gestützt und nicht fest mit der Wand verbunden hat. Um Schub¬ schäden am Aufleger und damit der Wand zu vermeiden, hat man zwischen Aufleger und Decke Gleitlager eingelegt.In buildings with walls and ceilings, the problem always arises of placing the ceilings between or on the walls in such a way that no damage occurs as a result of the natural dilatation. Conventionally, this was done in such a way that the ceiling was supported on supports at least on one side in each direction and was not firmly connected to the wall. In order to avoid thrust damage to the support and thus the wall, plain bearings have been inserted between the support and the ceiling.
Diese Technik hat sich an sich sehr bewährt, weist aber den Nachteil auf., dass wegen der dafür notwendigen Auflager die Wände übermässig dick gehalten werden müssen, was sich preis¬ lich negativ auswirkt. Zudem ist es notwendig, die Gleitlager sorgfältig einzulegen, um deren korrekte Funktion sicherzustel¬ len.This technique has proven itself in itself, but has the disadvantage that the walls have to be kept excessively thick because of the necessary supports, which has a negative price effect. In addition, it is necessary to carefully insert the slide bearings in order to ensure their correct functioning.
Um diese Nachteile zu vermeiden, sind Schubdübel entwickelt worden, bei welchen ein Stahldorn einseitig in eine Hülse hin¬ einragt, derart, dass, wenn er einseitig fest in die Wand oder Stirnseite einer Decke einbetoniert wird, das gegenüberliegende Element, also die Decke, in die die Hülse einbetoniert ist, auf dem freien Ende des Dornes gleiten kann. Damit lassen sich Auflager und Gleitlager umgehen, ohne der Decke das Dilatationsspiel zu nehmen.To avoid these disadvantages, push dowels have been developed in which a steel mandrel protrudes into a sleeve on one side, such that when it is firmly concreted on one side in the wall or front side of a ceiling, the opposite one Element, i.e. the ceiling, in which the sleeve is concreted, can slide on the free end of the mandrel. This means that supports and plain bearings can be bypassed without taking away the dilation play from the ceiling.
Diese bekannten Schubdübel weisen aber ebenfalls Nachteile auf, indem durch sie der Beton um sie herum enormen Belastun¬ gen ausgesetzt ist, wird doch das ganze Gewicht der sich auf sie abstützenden Decke in sehr kleinen Zonen in die Wand übertragen, was leicht zu Rissbildungen und sektoriell übermässigen Pressung des Betons führt. Dies wirkt sich aber direkt auf die Sicherheit des Bauwerkes aus und kann nur da¬ durch vermieden werden, dass eine grosse Zahl von Schubdübeln eingesetzt wird, was wiederum teuer zu stehen kommt.However, these known push dowels also have disadvantages in that the concrete around them is exposed to enormous stresses, since the entire weight of the ceiling which is supported on them is transferred into the wall in very small zones, which easily leads to cracks and is sectoral leads to excessive compression of the concrete. However, this has a direct impact on the safety of the building and can only be avoided by using a large number of push-in anchors, which in turn is expensive.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Schub- dübel zu schaffen, der die Vorteile der bekannten Elemente dieser Art aufweist, ohne ihre Nachteile zu übernehmen und dadurch sicherheitsmässig und wirtschaftlich gegenüber diesen interessanter ist.The invention is therefore based on the object of providing a push-in dowel which has the advantages of the known elements of this type without taking on their disadvantages and is therefore more interesting in terms of safety and economy than these.
Erfindungsgemäss wird diese Aufgabe durch einen Schubdübel ge- löst, wie er im Patentanspruch 1 definiert ist.According to the invention, this object is achieved by a push dowel as defined in claim 1.
Im folgenden wird eine vorteilhafte Ausführungsform des erfin- dungsgemässen Schubdübels anhand der Zeichnung erläutert. In dieser zeigtAn advantageous embodiment of the push anchor according to the invention is explained below with reference to the drawing. In this shows
Fig. 1 einen teilweisen Längsschnitt durch diesen Schubdübel, von der Seite her gesehen,1 is a partial longitudinal section through this dowel, seen from the side,
Fig. 2 einen teilweisen Längsschnitt durch denselben Schubdü¬ bel von oben her gesehen, und2 a partial longitudinal section through the same push dowel seen from above, and
Fig. 3 einen Querschnitt durch diesen Schubdübel.Fig. 3 shows a cross section through this push anchor.
In Fig. 1 erkennt man, in strichpunktierten Linien dargestellt, eine Betondecke 1, die mit einer Wand 2, in welche eine wei-In Fig. 1 one can see, shown in dash-dotted lines, a concrete ceiling 1, which with a wall 2, in which a white
OMPI tere Betondecke 3 eingelegt ist, über einen erfinduηgsge- mässen Schubdübel 4 verbunden ist. Letzterer besteht, wie am besten aus Fig. 2 hervorgeht, aus zwei Stahldornen 5 und zwei Hülsen 6. Die beiden Stahldorne 5 sind oben und unten durch Stahlplatten 7 miteinander verbunden, genau¬ so wie die beiden Hülsen 6 mittels zwei Stahlplatten 8 miteinander verbunden sind. Die Verbindung zwischen Stahl¬ platten und Stahldornen resp. Hülsen geschieht vorteilhaf¬ terweise durch Schweissung, und zwar in der Art, dass die Längsachsen M der Stahldorne 5 mit den Längsachsen m der Hülsen 6 zusammenfallen. Dadurch ist sichergestellt, dass die Hülsen 6 problemlos über die Stahldorne 5 gleiten kön¬ nen.OMPI tere concrete ceiling 3 is inserted, is connected via a push dowel 4 according to the invention. The latter consists, as best shown in FIG. 2, of two steel mandrels 5 and two sleeves 6. The two steel mandrels 5 are connected to one another at the top and bottom by steel plates 7, just as the two sleeves 6 are connected to one another by means of two steel plates 8 . The connection between steel plates and steel mandrels respectively. Sleeves are advantageously made by welding, in such a way that the longitudinal axes M of the steel mandrels 5 coincide with the longitudinal axes m of the sleeves 6. This ensures that the sleeves 6 can slide easily over the steel mandrels 5.
Die mittels der Stahlplatten 8 verbundenen Hülsen 6 sind ferner mit einer Frontplatte 9 verbunden, die dem einfachen Einlegen des Schubdübels 4 in die Schalung der Betondecke 1 vor dem Betonieren dient, da er mittels Nägeln, die durc die dafür vorgesehenen Löcher 10 (Fig. 3) eingeführt werden können, auf das Sσhalungsbrett der Stirnseite der Decke 1 von der Deckeninnenseite her aufgenagelt werden kann.The sleeves 6 connected by means of the steel plates 8 are also connected to a front plate 9, which is used for the simple insertion of the push dowel 4 into the formwork of the concrete ceiling 1 before concreting, since it is by means of nails which are provided by the holes 10 provided therefor (FIG. 3 ) can be introduced, can be nailed onto the board of the front of the ceiling 1 from the inside of the ceiling.
Indem für den erfindungsgemässen Schubdübel 4 ausschliess- lich hochfeste Werkstoffe, die auch korrosionsbeständig sind, verwendet werden, kann er problemlos überall eingesetzt wer¬ den. Dadurch, dass sowohl die Stahldorne 5 als auch die Hül- sen 6 durch Platten 7 und 8 verbunden sind, ergibt sich eine gegenüber den bekannten Schubdübeln wesentlich verbesserte Lastverteilung im Beton, was zu einer merklich verringerten Anzahl benötigter Schubdübel bei gleicher Belastbarkeit der Decke führt. Die lokale Pressung des Betons und damit die. Rissbildung im Bereich der einzelnen Dübel wird wesentlich verringert, was die Sicherheit des Bauwerkes erhöht.By using only high-strength materials which are also corrosion-resistant for the push-in dowel 4 according to the invention, it can be used anywhere without problems. The fact that both the steel mandrels 5 and the sleeves 6 are connected by plates 7 and 8 results in a significantly improved load distribution in the concrete compared to the known push-in anchors, which leads to a noticeably reduced number of push-in anchors required, with the same load capacity of the ceiling. The local pressure of the concrete and thus the. Cracking in the area of the individual dowels is significantly reduced, which increases the safety of the building.
Da je Schubdübel zwei Stahldorne Kräfte aufnehmen und über¬ tragen können, wird die für das Einlegen der für die vorge-Since two steel mandrels can absorb and transmit forces per push dowel, the one used to insert the
OMPI sehene maximale Belastung der Decke benötigten Elemente gegenüber herkömmlichen, einfachen Schubdübeln praktisch halbiert, was sich sehr positiv auf die Kosten auswirkt. Der erfindungsgemässe Schubdübel weist demnach gegenüber den bekannten Elementen dieser Art wesentliche Vorteile auf.OMPI seen maximum load on the ceiling required elements compared to conventional, simple push dowels practically halved, which has a very positive effect on costs. The push dowel according to the invention accordingly has significant advantages over the known elements of this type.
Gegenüber der beschriebenen AusführungsVariante lässt sich der erfindungsgemässe Schubdübel in einigen Punkten abändern, ohne dass dadurch Vorteile verloren gingen. So ist es möglich, die Hülsen 6 mit den sie verbindendenCompared to the embodiment variant described, the push dowel according to the invention can be modified in some points without any advantages being lost. So it is possible to connect the sleeves 6 with them
Platten 8 und die Frontplatte 9 nicht aus korrosionsfestem Stahl, sondern einteilig aus hochfestem Kunststoff zu fer¬ tigen. Ferner können auch mehr als zwei Dorne und Hülsen mittels Verbindungsplatten zu Einheiten verbunden werden.Plates 8 and the front plate 9 not made of corrosion-resistant steel, but in one piece from high-strength plastic. Furthermore, more than two mandrels and sleeves can be connected to units by means of connecting plates.
