Description

Die Erfindung betrifft ein Verbindungsstück zum Verbinden der Enden von Gewindestählen.The invention relates to a connector for Joining the ends of threaded steels.

Im Stahlbetonbau kommen häufig sogenannte Betonstähle zum Einsatz, die beispielsweise in Stahlbetonfertigteilplatten verwendet werden, wie sie etwa bei der Herstellung sogenannter fester Fahrbahnen für den Hochgeschwindigkeits-Schienenverkehr üblich sind. Hierbei sind die Betonstähle als Bewehrung in den Beton eingelegt und dienen dazu, die Zugkräfte aufzunehmen und auf den Beton zu übertragen (die auftretenden Druckspannungen übernimmt vorzugsweise der Beton).So-called reinforcing bars are often used in reinforced concrete construction used for example in Precast reinforced concrete slabs are used as they are for example in the manufacture of so-called solid Roadways for high-speed rail traffic are common. Here are the Reinforcing bars inserted as reinforcement in the concrete and serve to absorb the tensile forces and on the Transfer concrete (the compressive stresses that occur preferably takes over the concrete).

In diesem Zusammenhang erweist es sich in der Praxis oftmals als sinnvoll, die Betonstähle als sogenannte Bewehrungsmatten auszubilden und in den Beton einzulassen. Bei derartigen Bewehrungsmatten handelt es sich um geschweißte Betonstahlmatten, die aus sich rechtwinklig kreuzenden Stäben bestehen, welche Stäbe durch Widerstandspunktschweißen scherfest miteinander verbunden sind. Ausgangsmaterial sind kaltgewalzte gerippte Betonstähle mit Durchmessern von 4 mm bis 12 mm.In this context it turns out in practice often makes sense, the reinforcing bars as so-called Reinforcement meshes form and in the concrete involved. Acting in such reinforcement meshes it is welded reinforcing steel mesh that is made up of itself bars crossing at right angles are made up of which bars by shear-resistant welding with each other are connected. The raw material is cold rolled ribbed reinforcing bars with diameters from 4 mm to 12 mm.

Zur Sicherung des Stahl-Beton-Verbundsystems und der Verankerung im Beton sind die Oberflächen der Betonstähle in der Regel mit Rippen versehen, die zusätzlich der optischen Kennzeichnung dienen. Glatte und (mit wenig ausgeprägten Rippen) profilierte Betonstähle sind nur für spezielle geschweißte Bewehrungselemente zugelassen. Sind hierbei die Betonstähle oder jedenfalls ihre Enden mit einem Gewinde versehen, so spricht man von Gewindestählen.To secure the steel-concrete composite system and the Anchoring in concrete are the surfaces of the Reinforcing bars are usually provided with ribs that also serve as visual identification. Smoothness and profiled (with little pronounced ribs) Reinforcing steels are only for special welded ones Reinforcement elements approved. Here are the Reinforcing bars or at least their ends with a Providing threads, this is called threaded steels.

Zur Verbindung der Enden derartiger Gewindestähle sind aus dem Stand der Technik eine Reihe von Verbindungsstücken bekannt. Diese Verbindungsstücke sind jedoch in der praktischen Anwendung meist nur für einen bestimmten Gewindestahltyp einsetzbar, wobei in der Vergangënheit häufig Probleme beispielsweise in dem Fall aufgetreten sind, daß die zu verbindenden Enden der Gewindestähle nicht ganz koaxial zueinander stehen. Abgesehen davon sind die bekannten Verbindungsstücke auch von kompliziertem und mithin kostspieligem Aufbau sowie umständlich zu montieren.For connecting the ends of such threaded steels are a number of prior art Known connectors. These connectors are, however, mostly only in practical use can be used for a specific thread steel type, problems in the past for example in the event that the ends of the threaded steels to be connected are not quite are coaxial to each other. Apart from that, they are known connectors also of complicated and therefore expensive to set up and cumbersome assemble.

In der den nächstliegenden Stand der Technik bildenden FR-A 342078 wird die Verbindung von Betonstäben mit einem Verbindungsstück gezeigt. Das Verbindungsstück weist im Bereich von Widerlagern Langlöcher auf, wodurch das Verbindungsstück über die Betonstähle aufgesetzt werden kann. Die Betonstähle weisen jeweils an ihren Enden Köpfe auf, welche mit den Widerlagern des Verbindungsstücks zusammenwirken. Nachteilig bei dieser Ausführung ist es, daß, um dieses Verbindungsstück einsetzen zu können, die Betonteile, aus denen die Betonstähle herausragen und die beiden Köpfe der Betonstähle äußerst exakt zueinander positioniert sein müßten. Andernfalls könnte, beispielsweise bei einem zu großen Abstand der Köpfe der Betonstähle voneinander, das Verbindungsstück nicht über die Enden der Betonstähle aufgesetzt werden. Auch wenn die Köpfe der Betonstähle zu nah aneinander angeordnet sind, wäre es nicht möglich, das Verbindungsstück in eine feste Verbindung mit den beiden Betonstählen zu bringen, da zwischen dem Kopf und dem Widerlager des Verbindungsstücks Spiel wäre, welches nicht auszugleichen ist. Diese im Jahre 1904 angemeldete Vorrichtung, hat sich offenbar aus diesen Nachteilen nicht bewährt. In FR-A 342078, which forms the closest prior art, the Connection of concrete bars shown with a connector. The Connector has elongated holes in the area of abutments, which makes Connector over which reinforcing steel can be placed. The reinforcing bars each have heads at their ends, which with the abutments of the Interact with the connector. The disadvantage of this design is that to use this connector, the concrete parts that make up the Concrete bars protrude and the two heads of the concrete bars are extremely precise should be positioned to each other. Otherwise, for example with a too large a distance between the heads of the reinforcing bars, the connecting piece not placed over the ends of the reinforcing bars. Even if the heads of the Reinforcing bars are too close together, it would not be possible for that To bring the connector into a firm connection with the two reinforcing bars, since there would be play between the head and the abutment of the connector, which cannot be compensated. This device, registered in 1904, has apparently not proven itself from these disadvantages.

Ausgehend von den vorgenannten Unzulänglichkeiten und Nachteilen liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Verbindungsstück zum Verbinden der Enden von Gewindestählen bereitzustellen, das durch einfache mechanische Maßnahmen schnell und problemlos zu montieren ist. Des weiteren zielt die vorliegende Erfindung auf ein Verbindungsstück zum Verbinden der Enden von Gewindestählen ab, das breit und flexibel einsetzbar ist, wobei auch der Fall Berücksichtigung finden soll, in dem die zu verbindenden Enden der Gewindestähle nicht ganz koaxial zueinander orientiert sind.Based on the above shortcomings and Disadvantages of the present invention Task based on a connector for connecting the ends of threaded steels to provide that through simple mechanical measures quickly and is easy to assemble. Furthermore, the present invention on a connector for Joining the ends of threaded steels off that wide and can be used flexibly, which is also the case Should be taken into account, in which the connecting ends of the threaded steels are not quite are coaxially oriented.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention the object is achieved by the features of claim 1.

Ist das Verbindungsstück erfindungsgemäß in der vorgenannten Weise ausgebildet, so ermöglichen die einseitig offenen Langlöcher in den sich rechtwinklig zu den Verbindungsstegen erstreckenden Widerlagern, daß das Verbindungsstück direkt über die Enden der Gewindestähle sowie über die zuvor auf die Enden der Gewindestähle aufgeschraubten Muttern gelegt werden kann. Im Anschluß daran werden die Muttern mit der Hand oder mit einem passenden Ringschlüssel angezogen.Is the connector according to the invention in the trained above, so allow oblong holes open on one side in the right angle abutments extending to the connecting webs, that the connector is directly over the ends of the Thread steels as well as those previously on the ends of the Threaded steels are screwed on nuts can. Then the nuts with the Hand or with a suitable ring spanner dressed.

Obwohl das Verbindungsstück gemäß der vorliegenden Erfindung eine relativ einfache und klar konzipierte Struktur aufweist, vermag es die technische Funktion des Verbindens der Enden von Gewindestählen auf überzeugende Weise zu erfüllen, wobei es als besonders überraschend und für den Fachmann in dieser Form nicht vorhersehbar angesehen werden kann, daß die technische Ausgestaltung der Erfindung es auch erlaubt, die Enden von Gewindestählen miteinander zu verbinden, die nicht exakt koaxial zueinander angeordnet sind. Des weiteren wird man es nicht zuletzt unter dem Gesichtspunkt der Zeit- und Kostenersparnis zu schätzen wissen, daß das vorgenannte Verbindungsstück eine schnelle Montage gestattet. Sollte sich hierbei wider Erwarten herausstellen, daß die Montage nicht ordnungsgemäß erfolgt ist, so ist es bei der vorliegenden Erfindung jederzeit möglich, durch Lösen der festgezogenen Muttern das Verbindungsstück noch einmal abzunehmen, korrekt zu positionieren und wieder festzulegen.Although the connector according to the present Invention a relatively simple and clearly designed Has structure, it can perform the technical function connecting the ends of threaded steels convincing way to fulfill it as particularly surprising and for the expert in this Form can not be foreseen that the technical design of the invention it too allowed the ends of threaded steels to close together connect that are not exactly coaxial to each other are arranged. Furthermore, you will not lastly from the point of view of time and Cost savings appreciate that aforementioned connector a quick assembly allowed. Should be contrary to expectations point out that the assembly is not correct is done, it is in the present invention possible at any time by loosening the tightened Nuts to remove the connector again, to position and fix correctly.

Als weiterer entscheidender Vorteil kann bei der vorliegenden Erfindung aufgeführt werden, daß der Abstand zwischen den Enden der Gewindestähle relativ klein gehalten werden kann, da, wie vorstehend erläutert, die Muttern vor der Montage des Verbindungsstücks aufgeschraubt werden. Diese Tatsache wirkt sich insbesondere auf die Stabilität beispielsweise von Stahlbetonfertigteilplatten positiv aus, die durch Verbindungsstücke gemäß der vorliegenden Erfindung zueinander fixiert werden.Another decisive advantage of the present invention listed that the Distance between the ends of the threaded steels relative can be kept small since, as above explains the nuts before installing the Be screwed on. This The fact affects stability in particular for example of precast reinforced concrete slabs positive by the connectors according to the present invention are fixed to each other.

Gemäß einer besonders erfinderischen Ausführungsform ist das Verbindungsstück als längliches hohles quaderförmiges Teil ausgebildet, dessen beide voneinander am weitesten beabstandeten Stirnseiten die Widerlager und dessen mindestens eine, vorzugsweise zwei die Widerlager verbindenden Seitenflächen die Verbindungsstege definieren. Hierbei wird die einfache und schnelle Montage durch Festziehen der Muttern insbesondere dann begünstigt, wenn mindestens eine, vorzugsweise zwei Seitenflächen des quaderförmigen Teils zwischen den Widerlagern ausgespart sind, so daß die Muttern gut per Hand oder mit einem Ringschlüssel zugänglich sind. According to a particularly inventive embodiment is the connector as an elongated hollow cuboid part formed, both of which most distant end faces the abutments and its at least one, preferably two connecting the abutments Side surfaces define the connecting webs. Here, the simple and quick installation Tightening the nuts particularly favors if at least one, preferably two side surfaces the cuboid part between the abutments are recessed so that the nuts can be done by hand or are accessible with a ring spanner.

In diesem Falle erweist es sich als zweckmäßig, wenn die Langlöcher zu einer der ausgesparten Seitenflächen des quaderförmigen Teils hin offen sind, so daß das Verbindungsstück ohne weiteres auf die Enden der Gewindestähle aufgesetzt werden kann und im Anschluß daran die Muttern beispielsweise mit einem passenden Ringschlüssel festgezogen werden können.In this case it proves useful if the elongated holes to one of the recessed Side faces of the cuboid part open are so that the connector is easily on the ends of the threaded steels can be put on and then, for example, the nuts be tightened with a suitable ring spanner can.

Gemäß einer vorteilhaften Weiterbildung der vorliegenden Erfindung ist die Breite der Langlöcher zumindest gleich dem Durchmesser der Gewindestähle. Hierbei kann es empfehlenswert sein, zur Kompensation geringfügiger Toleranzen die Breite der Langlöcher etwas größer als den Durchmesser der Gewindestähle zu wählen. Auch die letztgenannte technische Maßnahme dient dazu, gegebenenfalls die Tatsache auszugleichen, daß die Enden der zu verbindenden Gewindestähle nicht ganz koaxial zueinander angeordnet sind.According to an advantageous development of the The present invention is the width of the elongated holes at least equal to the diameter of the threaded steels. Here it can be recommended for compensation minor tolerances the width of the elongated holes slightly larger than the diameter of the threaded steels choose. Also the latter technical measure serves the fact if necessary balance that the ends of the to be joined Thread steels are not completely coaxial with each other are arranged.

Eine besondere Stabilität verleiht das Verbindungsstück gemäß der vorliegenden Erfindung den zu verbindenden Elementen dann, wenn die Länge der Langlöcher in etwa gleich der Hälfte der Höhe der Widerlager ist, denn in diesem Fall verteilen sich sowohl die Zugspannungen als auch die Druckkräfte gleichmäßig über das Verbindungsstück.This gives it particular stability Connector according to the present invention elements to be connected if the length of the Elongated holes approximately equal to half the height of the Abutment is because in this case they spread out both the tensile stresses and the compressive forces evenly over the connector.

Zur Vermeidung von Verletzungen, die sich die montierenden Personen in der Vergangenheit häufig zugezogen haben, ist es empfehlenswert, die Ränder der Verbindungsstege und die Ränder der Widerlager bündig miteinander abschließen zu lassen. Dies erleichtert auch die Lagerhaltung sowie den Transport der Verbindungsstücke in gestapelter Form.To avoid injury to yourself assemblers in the past frequently have drawn, it is recommended the edges the connecting webs and the edges of the abutments to be flush with each other. This also facilitates warehousing and transportation of the connectors in a stacked form.

Bildet man das Verbindungsstück in besonders erfinderischer Weise weiter, so ist in den Eckbereichen zwischen Verbindungssteg und Widerlager jeweils eine Nase angeordnet. Diese Nasen entfalten ihre Wirkung, wenn die Muttern nach Aufsetzen des Verbindungsstücks angezogen sind, wobei die Nasen als Sicherung für die Muttern dienen und ein Abfallen oder Abrutschen des Verbindungsstücks von den Enden der Gewindestähle verhindern.Forming the connector in particular inventive way, is in the Corner areas between connecting bridge and abutment one nose each. These noses unfold their effect when the nuts after putting on the Connector are tightened, the lugs as Secure the nuts and prevent them from falling off or the connector slips off the ends prevent the thread steels.

Hierzu sind die Nasen zweckmäßigerweise der ausgesparten Seitenfläche des quaderförmigen Teils zugeordnet, zu welcher ausgesparten Seitenfläche die Langlöcher hin offen sind. In der Praxis hat es sich als vorteilhaft herausgestellt, die Nasen in rechteckiger Form auszubilden.For this purpose, the noses are expediently the recessed side surface of the cuboid part assigned to which recessed side surface the Elongated holes are open. In practice it did turned out to be advantageous, the noses in to form a rectangular shape.

Hinsichtlich der Formgebung des Verbindungsstücks ist des weiteren eine Ausgestaltung bevorzugt, bei der die Verbindungsstege von rechteckiger Form und/oder die Widerlager von quadratischer Form sind.Regarding the shape of the connector further preferred an embodiment in which the connecting webs of rectangular shape and / or the abutments are square in shape.

Weitere Ausgestaltungen, Merkmale und Vorteile der vorliegenden Erfindung werden nachfolgend anhand des in den Figuren 1 und 2 exemplarisch dargelegten Ausführungsbeispiels erläutert. Es zeigt:

Further refinements, features and advantages of the present invention are explained below on the basis of the exemplary embodiment illustrated by way of example in FIGS. 1 and 2. It shows:
Figure 1
a bottom view of an embodiment of a connector for connecting the ends of threaded steel according to the present invention; and
Figure 2
2 shows a view of an end face of the exemplary embodiment from FIG. 1.

Das in Fig. 1 gezeigte Verbindungsstück dient dazu, die Enden von Gewindestählen 10 und 12 miteinander zu verbinden. Hierbei handelt es sich bei den Gewindestählen 10 und 12 um Betonstähle, die mit einem Gewinde versehen sind, auf das in den jeweiligen Endbereichen Muttern 60 und 62 aufschraubbar sind.The connector shown in Fig. 1 is used the ends of threaded steels 10 and 12 together connect. This is the Threaded steels 10 and 12 um reinforcing bars that with are provided with a thread in the respective end areas nuts 60 and 62 can be screwed on.

Das Verbindungsstück weist hierbei zwei sich in Längsrichtung erstreckende Verbindungsstege 20 und 22 auf, an deren Enden jeweils ein sich zu diesen Verbindungsstegen 20 und 22 rechtwinklig erstreckendes Widerlager 30 und 32 angeordnet ist, von denen jedes ein einseitig offenes Langloch 40 und 42 aufweist. Hierbei ist der Darstellung der Fig. 1 entnehmbar, daß das Langloch 40 dem Widerlager 30 und das Langloch 42 dem Widerlager 32 zugeordnet ist, wobei das Ende des Gewindestahls 10 im Widerlager 30 (vgl. auch Fig. 2) und das Ende des Gewindestahles 12 im Widerlager 32 Aufnahme findet.The connector has two in here Connecting webs 20 and 22 extending in the longitudinal direction at the ends of each one of them Crosspieces 20 and 22 at right angles extending abutment 30 and 32 is arranged, each of which has a slot 40 and 42 has. Here is the representation of Fig. 1st Removable that the slot 40, the abutment 30 and the slot 42 is assigned to the abutment 32, the end of the threaded steel 10 in the abutment 30 (see also FIG. 2) and the end of the threaded steel 12 takes place in the abutment 32.

Das in Fig. 1 dargestellte Verbindungsstück ist insgesamt als längliches hohles quaderförmiges Teil ausgebildet, dessen beide voneinander am weitesten beabstandeten Stirnseiten (in Fig. 1 oben und unten) die Widerlager 30 und 32 und dessen beide die Widerlager 30 und 32 verbindenden Seitenflächen die Verbindungsstege 20 und 22 definieren. Um einen Zugang zu den Muttern 60 und 62 zu schaffen, die nach Aufsetzen des Verbindungsstücks festzuziehen sind, sind die zwei Seitenflächen 24 und 26 (vgl. Fig. 2) des quaderförmigen Teils zwischen den Widerlagern 30 und 32 ausgespart, wodurch bei der Darstellung der Fig. 1 eine freie Sicht auf die Enden der Gewindestähle 10 und 12 mit den darauf aufgeschraubten Muttern 60 und 62 ermöglicht wird. Hierbei ist der Darstellung der Fig. 2 entnehmbar, daß das Langloch 40 zur ausgesparten Seitenfläche 24 des quaderförmigen Teils hin offen ist. Obwohl dies aus perspektivischen Gründen der Darstellung der Fig. 2 nicht entnehmbar ist, gilt natürlich, daß das Langloch 42 ebenso zur ausgesparten Seitenfläche 24 des quaderförmigen Teils hin offen ist.The connector shown in Fig. 1 is overall as an elongated hollow cuboid part trained, the two of which are farthest from each other spaced end faces (in Fig. 1 above and below) the abutments 30 and 32 and both of which the Abutments 30 and 32 connecting the side surfaces Define connecting webs 20 and 22. To one To create access to nuts 60 and 62 that are after Attaching the connector must be tightened, are the two side surfaces 24 and 26 (see FIG. 2) of the cuboid part between the abutments 30 and 32 recessed, which means that in the representation of the Fig. 1 is a clear view of the ends of the Thread steels 10 and 12 with those on them screwed nuts 60 and 62 is made possible. 2 can be seen, that the slot 40 to the recessed side surface 24th of the cuboid part is open. Although this is for perspective reasons of the representation of Fig. 2 is not removable, of course it applies that the Elongated hole 42 also to the recessed side surface 24 of the cuboid part is open.

Um beispielsweise durch Nicht-Koaxialität der Enden der Gewindestähle 10 und 12 bedingte Toleranzen ausgleichen zu können, ist die Breite der Langlöcher 40 und 42 bei dem in den Figuren 1 und 2 gezeigten Ausführungsbeispiel geringfügig größer als der Durchmesser der Gewindestähle 10 und 12. Hierdurch wird ein einfaches und problemloses Aufsetzen des Verbindungsstücks auf den Enden der Gewindestähle 10 und 12 ermöglicht, bevor das Verbindungsstück dann durch Festziehen der Muttern 60 und 62 arretiert wird. Des weiteren ist Fig. 2 entnehmbar, daß die Länge des Langlochs 40 in etwa gleich der Hälfte der Höhe des Widerlagers 30 ist, was dem Verbindungsstück eine besonders gute mechanische Stabilität verleiht. Vorgenannte Dimensionierung gilt selbstverständlich in gleicher Weise für das Langloch 42.For example, by non-coaxiality of the ends of the threaded steels 10 and 12 conditional tolerances to be able to compensate is the width of the elongated holes 40 and 42 in that shown in Figures 1 and 2 Embodiment slightly larger than that Diameter of the threaded steels 10 and 12. Hereby becomes a simple and problem-free installation of the Connector on the ends of the threaded steel 10 and 12 allows before the connector then locked by tightening nuts 60 and 62 becomes. Furthermore, Fig. 2 can be seen that the Length of the elongated hole 40 is approximately equal to half the Height of abutment 30 is what the connector gives a particularly good mechanical stability. Of course, the aforementioned dimensioning applies in the same way for the elongated hole 42.

Die das Verbindungsstück montierende Person wird es zur Vermeidung von Verletzungen bei der Montage besonders zu schätzen wissen, daß die Ränder der Verbindungsstege 20 und 22 und die Ränder der Widerlager 30 und 32 bündig miteinander abschließen, wie dies für das Widerlager 30 exemplarisch in Fig. 2 gezeigt ist. The person assembling the connector becomes it to avoid injuries during assembly especially appreciate that the edges of the Crosspieces 20 and 22 and the edges of the Close abutments 30 and 32 flush with each other, as for the abutment 30 as an example in FIG. 2 is shown.

Wie vorstehend bereits ausgeführt, dienen die Muttern 60 und 62 der Arretierung des Verbindungsstücks gemäß der vorliegenden Erfindung.
