Abstract

The invention relates to a dowel pin for web reinforcements for reinforced concrete slabs, with several dowels (3) arranged parallel with and at a distance from each other. Said dowels are fixed with a dowel head (5, 6) at one end to a single dowel anchor channel (2) with a positive fit or by spot welding.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer Dübelleiste für Schubbewehrungen für Stahlbetonplatten, mit mehreren, parallel und im Abstand zueinander angeordneten Dübeln, die an beiden Enden ihres Dübelschaftes jeweils einen z. B. tellerförmig verbreiterten Dübelkopf aufweisen und mit ihrem einen Ende an einer gemeinsamen Dübelhalteschiene mittels mindestens eines stirnseitig angeformten Verbindungsstücks befestigt sind.The invention relates to a method for producing a Dowel bar for shear reinforcement for reinforced concrete slabs, with several, arranged in parallel and at a distance from each other Dowels, one at each end of their dowel shaft z. B. have plate-shaped widened dowel head and with one end on a common dowel holding rail by means of at least one connecting piece formed on the end face are attached.

Aus Dübelleisten aufgebaute Schubbewehrungen dienen in Platten oder Balken aus Stahlbeton im Bereich von Auflagerstellen, insbesondere im Bereich von Stützenanschlüssen, der Aufnahme der dort infolge der Stützenkräfte auftretenden Querkräfte und bilden somit eine Durchstanzbewehrung.Shear reinforcements made of dowel bars serve in Reinforced concrete slabs or beams in the area of support points, especially in the area of column connections, the Inclusion of those occurring there as a result of the support forces Transverse forces and thus form a punching shear reinforcement.

Um die Herstellung der Dübelleisten zu vereinfachen, ist es bekannt (EP 0 744 508 A1), die Dübel an der Dübelhalteschiene lösbar zu befestigen, beispielsweise anzuschrauben.To simplify the manufacture of dowel strips, it is known (EP 0 744 508 A1), the dowels on the dowel holding rail to be releasably attached, for example screwed on.

Es ist ebenfalls bekannt (DE A 2 829 941 oder DE A 2 631 505), die Befestigung kraftschlüssig durch Drehung eines Verbindungsstücks herzustellen. Bei einer solchen Ausführung ist keine Schraube und kein Werkzeug für die Befestigung des Dübels der Dübelhalteschiene erforderlich. Das Verbindungsstück ist beispielsweise ein der Stirnseite des Dübels angeformtes T-Stück, das durch eine Öffnung der Dübelhalteschiene gesteckt und verdreht wird, so daß seine seitlichen Arme die Dübelhalteschiene hintergreifen.It is also known (DE A 2 829 941 or DE A 2 631 505), the attachment by turning a Manufacture connector. With such an execution is not a screw and not a tool for fastening the Dowels of the dowel holding rail required. The connector is for example one of the face of the anchor molded T-piece, which through an opening of the dowel holding rail is inserted and twisted so that its lateral Arms reach behind the dowel holding rail.

Diese formschlüssige Verbindung zwischen dem Dübel und der Dübelhalteschiene ist zwar einfach, z. B. auf einer Baustelle auszuführen, sie kann jedoch ebenso einfach wieder gelöst werden bzw. sich einfach lösen. Dadurch besteht die Gefahr, daß einzelne oder mehrere Dübel auf der Baustelle von der Dübelhalteschiene absichtlich entfernt werden oder sich unbemerkt bzw. ungewollt lösen und abfallen. Die Schubbewehrung entspricht dann nicht mehr der für die statische Berechnung zugrunde gelegten Ausführung. Eine solche Abweichung von der vorgegebenen Ausführung kann nach dem Betonierung der Stahlbetonplatte nicht mehr festgestellt werden. Um dieses Risiko einer unzureichenden Bewehrung auszuschließen, ist es daher erforderlich, den Einbau der Schubbewehrung bis zum Betoniervorgang so zu überwachen, daß sichergestellt ist, daß keine Dübel von der Dübelhalteschiene gelöst und entfernt werden.This positive connection between the dowel and the Dowel holding rail is simple, e.g. B. on a construction site to perform, however, it can be solved just as easily will or just come loose. This creates the risk that single or multiple dowels on site from the Dowel holding rail to be removed intentionally or yourself solve unnoticed or unintentionally and fall off. The shear reinforcement then no longer corresponds to that for the static one Calculation based on execution. Such Deviation from the specified execution can after Concreting of the reinforced concrete slab no longer found become. To avoid this risk of insufficient reinforcement exclude, it is therefore necessary to install the Monitor the shear reinforcement until the concreting process so that it is ensured that no dowels from the dowel holding rail be solved and removed.

Bei einer Dübelleiste (DE 296 12 053 U1) der eingangs genannten Gattung ist das Verbindungsstück als federbelastete Klemmvorrichtung ausgestaltet. Mittels der Klemmvorrichtung können die einzelnen Dübeln an der Dübelhalteschiene angebracht und mit einer zusätzlichen Befestigungsvorrichtung arretiert werdenIn the case of a dowel bar (DE 296 12 053 U1) mentioned type is the connector as a spring-loaded Designed clamping device. By means of the clamping device the individual dowels on the dowel holding rail attached and with an additional fastening device be locked

Bei einer anderen bekannten Dübelleiste (EP 0 495 334 B1) sind die Dübel an die Dübelhalteschiene angeschweißt. Die bei einer solchen Schweißverbindung erforderliche Erhitzung kann dazu führen, daß sich die Dübelhalteschiene verformt und deshalb nachträglich gerichtet werden muß. Durch den Schweißvorgang der bekannten Art können auch Materialveränderungen im Dübelkopf auftreten, die zu einer Verminderung der Belastbarkeit führen.In another known dowel bar (EP 0 495 334 B1) the dowels are welded to the dowel holding rail. The at such a welded connection may require heating cause the dowel holding rail to deform and therefore must be judged later. By the Welding process of the known type can also material changes occur in the dowel head, which leads to a reduction in the Resilience.

Aufgabe der Erfindung ist es daher, eine Dübelleiste der eingangs genannten Gattung so auszubilden, daß sie einfacher, kostengünstiger und zuverlässiger, d.h. ohne Beeinträchtigung der Funktionen von Dübelhalteschiene und/oder Dübel, hergestellt werden kann, daß aber eine nachträgliche Veränderung durch Lösen einzelner Dübel ausgeschlossen ist.The object of the invention is therefore a dowel bar trained in the beginning so that they are easier, cheaper and more reliable, i.e. without interference the functions of the dowel holding rail and / or dowel, can be produced, but that a subsequent Modification by loosening individual dowels is excluded.

Diese Aufgabe wird bei einer Dübelleiste der eingangs genannten Art allgemein dadurch gelöst, daß das stirnseitige Verbindungsstück des Dübelkopfes durch einen Kaltformvorgang zu einem formschlüssigen Verbindungseingriff mit der Dübelhalteschiene verformt ist. Das einfach gestaltete Verbindungsstück erfordert nur einen geringen Mehraufwand bei der Herstellung des Dübels. Die Dübel können bereits vorgefertigt oder direkt auf der Baustelle beispielsweise durch Verstemmen schnell und dauerhaft mit der Dübelhalteschiene verbunden werden. Ein unbeabsichtigtes Lösen der Dübel von der Dübelhalteschiene ist nicht möglich.This task is the beginning of a dowel bar mentioned type generally solved in that the front Connector of the dowel head through a cold forming process for a positive connection intervention with the Dowel holding rail is deformed. The simply designed Connector requires little additional effort the manufacture of the dowel. The dowels can already prefabricated or directly on site, for example by caulking quickly and permanently with the dowel holding rail get connected. An unintentional loosening of the Dowels from the dowel holding rail are not possible.

Einer besonders vorteilhaften Ausgestaltung des Erfindungsgedankens zufolge, wobei das Verbindungsstück formschlüssig in einer Öffnung der Dübelhalteschiene aufgenommen wird, ist vorgesehen, daß das formschlüssig in der Öffnung der Dübelhalteschiene aufgenommene Verbindungsstück ein stirnseitig am Dübelkopf angeformter Nietzapfen ist, der durch die Öffnung der Dübelhalteschiene ragt und vernietet wird. A particularly advantageous embodiment of the inventive concept according to, wherein the connector is form-fitting in an opening of the dowel holding rail is received provided that the form-fitting in the opening of the Dowel holding rail included connector rivet is formed on the face of the dowel head protrudes and rivets through the opening of the dowel holding rail becomes.

Bei der Herstellung der Dübel kann der Nietzapfen in einfacher Weise und mit nur geringem zusätzlichem Fertigungsaufwand angeformt werden. Die Dübelhalteschiene wird vorzugsweise nur an denjenigen Stellen mit jeweils einer Öffnung als Bohrung oder Stanzung versehen, an denen nach den statischen Vorgaben ein Dübel angeordnet werden soll. Die Verbindung geschieht in einfacher Weise dadurch, daß der durch die Öffnung gesteckte Nietzapfen vernietet wird. Die so hergestellte formschlüssige Verbindung ist nachträglich nicht lösbar, so daß einzelne Dübel nicht entfernt werden können.The rivet pin can be used in simple way and with little additional manufacturing effort be molded on. The dowel holding rail is preferably only in those places with one each Provide the opening as a hole or a punch on which according to the static an anchor should be arranged. The Connection happens in a simple way that the rivets inserted through the opening. The so Established positive connection is not retrospectively detachable so that individual dowels cannot be removed.

Anstelle oder zusätzlich zu der zuvor erwähnten formschlüssigen Aufnahme eines stirnseitig angeformten Verbindungsstücks in der Öffnung der Dübelhalteschiene kann gemäß einer anderen vorteilhaften Ausführung des grundsätzlichen Erfindungsgedankens auch vorgesehen sein, daß die Dübelhalteschiene in eine stirnseitige Quernut des Dübelkopfes eingelegt wird und daß die beiden die Quernut begrenzenden stirnseitigen Ränder des Dübelkopfes seitlich zur Dübelhalteschiene verstemmt werden.Instead of or in addition to the previously mentioned positive Inclusion of a connecting piece formed on the face in the opening of the dowel holding rail can according to another advantageous embodiment of the basic idea of the invention also be provided that the dowel holding rail in a front transverse groove of the dowel head is inserted and that the two front edges of the transverse groove delimiting the Dowel head are caulked sideways to the dowel holding rail.

Die der Erfindung zugrunde liegende Aufgabe läßt sich gemäß einer weiteren Ausführung bei einer Dübelleiste der eingangs genannten Art jedoch auch ohne besonderes Verbindungsstück auf einfache Weise auch dadurch lösen, daß die Dübelhalteschiene jedenfalls in dem für die Dübel vorgesehenen Abstand Öffnungen aufweist und die Dübel stirnseitig durch in den Öffnungen vorgesehene Schweißpunkte mit der Dübelhalteschiene verbunden werden.The object underlying the invention can be according to Another version with a dowel bar at the beginning mentioned type but also without a special connector solve in a simple manner that the dowel holding rail at least in the distance provided for the dowels Has openings and the end of the dowels in the Weld spots provided for openings with the dowel holding rail get connected.

Die Anformung eines stirnseitigen Verbindungsstücks an den Dübeln ist also dabei entbehrlich. Die Art der vorgeschlagenen Punktschweißung führt zudem zu keiner nachteiligen Verformung der Dübelhalteschiene und zu keiner Verminderung der Belastbarkeit der Verbindung, wie dies bei dem oben erwähnten an sich bekannte Anschweißen der Fall ist. Ein weiterer Vorteil ist, daß die in den Öffnungen vorgesehenen Schweißpunkte gegenüber der Stärke der Dübelhalteschiene nicht auftragen. Auf diese Weise wird eine besonders einfache Schweißverbindung ermöglicht, die schnell und mit geringem Aufwand herstellbar ist.The molding of an end connector on the Dowelling is therefore unnecessary. The type of proposed Spot welding also does not lead to any disadvantage Deformation of the dowel holding rail and no reduction the resilience of the connection, as in the above known welding is the case. On Another advantage is that the provided in the openings Spot welds against the strength of the dowel holding rail do not apply. This way it becomes a particularly simple one Allows welded joint to be made quickly and with little Effort can be produced.

Von Vorteil ist es, wenn die Schweißpunkte die Öffnungen in der Dübelhalteschiene jedenfalls seitlich vollständig oder im wesentlichen vollständig ausgefüllt werden, um die Aufnahme von Kräften weiter zu verbessern.It is advantageous if the weld spots in the openings the dowel holding rail at least laterally completely or in to be filled in substantially to complete the inclusion of forces to improve further.

Bei dieser und den anderen Ausführungen kann die Dübelhalteschiene zur Drehsicherung in einer stirnseitigen Quernut des Dübelkopfes aufgenommen werden.In this and the other versions, the dowel holding rail can to prevent rotation in a front transverse groove of the Dowel head are included.

Besonders vorteilhaft ist es, wenn die Dübelhalteschiene aus Flachstahl ausgeführt ist.It is particularly advantageous if the dowel holding rail is made of Flat steel is executed.

Die Dübelleiste 1 besteht aus einer Dübelhalteschiene 2 und mehreren daran im Abstand und parallel zueinander angeordneten Dübeln 3. Jeder Dübel 3 weist einen länglichen Dübelschaft 4 auf, der glatt oder mit Rippen versehen sein kann. An beiden Enden des Dübelschaftes 4 ist jeweils ein tellerförmig verbreiterter Dübelkopf 5 bzw. 6 mit einer ebenen oder im wesentlichen ebenen Stirnfläche 11 für die Anlage an der Dübelhalteschiene 2 angeformt oder angeschweißt.The dowel bar 1 shown in Fig. 1 is used for construction one consisting of several such dowel strips Shear reinforcement in a reinforced concrete slab or similar Reinforced concrete section. The dowel bar 1 consists of a Dowel holding rail 2 and several at a distance and dowels arranged parallel to each other 3.Each dowel 3 has an elongated dowel shaft 4 which is smooth or with Ribs can be provided. At both ends of the dowel shaft 4 is in each case a plate-shaped widened dowel head 5 or 6 with a flat or essentially flat end face 11 molded onto the dowel support rail 2 or welded.

    Jeweils der eine Dübelkopf 5 ist an der Dübelhalteschiene 2 formschlüssig befestigt. Die Dübelhalteschiene 2 ist eine aus Flachstahl bestehende Blechschiene, die an der Stirnseite der Dübelköpfe 5 anliegt.One dowel head 5 each is on the dowel holding rail 2 positively attached. The dowel holding rail 2 is one of Flat steel existing sheet metal rail on the front of the Dowel heads 5 abut.

    An den für die Anordnung eines Dübels 3 bestimmten Stellen ist aus der Dübelhalteschiene 2 jeweils eine Öffnung 7 gebohrt oder gestanzt (Fig. 2). Am Dübelkopf 5 ist stirnseitig ein aus der Stirnfläche 11 herausragendes, als Nietzapfen 8' ausgebildetes Verbindungsstück 8 angeformt, welches bei der Montage der Dübelleiste 1 durch die Öffnung gesteckt und durch Vernieten mit einem Nietkopf 9 versehen wird (Fig. 3).At the points intended for the arrangement of a dowel 3 is an opening 7 from the dowel holding rail 2 drilled or punched (Fig. 2). The end of the dowel head 5 a protruding from the end face 11 as a rivet 8 'formed connecting piece 8, which at the installation of the dowel bar 1 through the opening and is provided with a rivet head 9 by riveting (FIG. 3).

    In Fig. 4 ist gezeigt, daß im Bereich des stirnseitig angeformten Nietzapfens 8 eine Quernut 10 in der Stirnfläche 11 des Dübelkopfes 5 vorgesehen werden kann, um eine Verdrehsicherung der in der Quernut 10 aufgenommenen Dübelhalteschiene 2 zu bilden.In Fig. 4 it is shown that in the area of the front molded rivet 8 a transverse groove 10 in the end face 11 of the dowel head 5 can be provided to a Protection against rotation of those accommodated in the transverse groove 10 To form dowel support rail 2.

    Das Ausführungsbeispiel nach Fig. 5 unterscheidet sich von den vorher beschriebenen Ausführungsbeispielen im wesentlichen dadurch, daß auf einen Nietzapfen 8 und Öffnungen 7 verzichtet wird. Die aus Flachstahl bestehende Dübelhalteschiene 2 ist hierbei in die stirnseitige Quernut 10 des Dübelkopfes 5 eingelegt. Sodann sind die Ränder 10a der Quernut 10 so nach innen verstemmt, daß sie die Dübelhalteschiene 2 unlösbar festhalten.5 differs from the previously described embodiments essentially in that on a rivet 8 and openings 7th is waived.
