Description

Die Erfindung betrifft eine Schraubverbindung für kraftübertragende Stäbe, insbesondere Bewehrungsstäbe für Stahlbetonteile der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The invention relates to a screw connection for force-transmitting rods, in particular reinforcing rods for reinforced concrete parts of the type specified in the preamble of claim 1.

In der EP 0 059 680 B1 ist eine Ankerverbindung beschrieben, mittels der in zwei verschiedenen Betonabschnitten angeordnete Anker verbunden werden. Dabei ist an einem der Anker an einem Ende durch Schmieden des Ankermaterials ein Aufnahmekopf gestaltet, in dem eine Bohrung mit Innengewinde angeordnet ist. An einem Ende des anderen Ankers ist ein vorzugsweise durch Gewinderollen gefertigtes Gewinde vorgesehen, wobei der Durchmesser am Grund der Schraubennut mindestens dem Ursprungsdurchmesser des Ankers entspricht. Dazu ist es erforderlich, dieses Ende des Ankers zuvor im Durchmesser zu vergrößern, was ebenfalls in geeigneter Weise durch Schmieden erfolgt.EP 0 059 680 B1 describes an anchor connection, by means of which anchors arranged in two different concrete sections are connected. In this case, a receiving head is designed on one of the anchors at one end by forging the anchor material, in which a bore is arranged with internal thread. At one end of the other armature, a thread preferably made by thread rolling is provided, wherein the diameter at the bottom of the screw groove corresponds at least to the original diameter of the armature. For this purpose, it is necessary to increase this end of the anchor previously in diameter, which also takes place in a suitable manner by forging.

Die EP 0 077 952 A1 offenbart ein Verfahren zur Herstellung eines Stabendes für die Verbindung von Bewehrungsstäben im Stahlbetonbau. Dabei ist ein mit konischer Aufweitung im Bereich des auslaufenden Gewindes geschältes Stabende vorgesehen, auf das mit einem Gewinderollwerkzeug ein Gewinde aufgerollt ist. Um die Gewindespitzen auch im Bereich des auslaufenden Gewindes voll auszubilden, muß die konische Aufweitung entsprechend bestimmt sein.EP 0 077 952 A1 discloses a method for producing a bar end for the connection of reinforcing bars in reinforced concrete construction. Here, a shelled with conical expansion in the region of the expiring thread bar end is provided, on which a thread is rolled up with a thread rolling tool. To fully develop the thread crests in the region of the expiring thread, the conical expansion must be determined accordingly.

Aus der DE 197 53 755 C2 ist eine schlupfarme Schraubverbindung für Stäbe im Bauwesen bekannt. Damit sollen zwei Bauteile verbunden werden, von denen das eine ein stabförmiges Element ist und das andere ein muffenförmiges Element, in das der Stab eindrehbar ist. Eines der Elemente weist an seiner dem anderen Element zugekehrten Kontur eine Gewindeform auf. Zum besseren Einspuren der ineinanderzufügenden Elemente kann am vorderen Ende des Stabes ein Teilgewinde oder an der Muffe eine flache Fase vorgesehen sein.From DE 197 53 755 C2 a slip screwed connection for rods in construction is known. Thus, two components are to be connected, one of which is a rod-shaped element and the other a sleeve-shaped element into which the rod is screwed. One of the elements has a thread shape on its contour facing the other element. For better meshing of the elements to be joined, a partial thread or a flat bevel can be provided on the sleeve at the front end of the rod.

In der DE 196 26 649 A1 ist eine Schraubkupplung für kraftübertragende Stäbe, insbesondere Bewehrungsstäbe für Stahlbetonteile, beschrieben. Dabei ist eine Hülse vorgesehen, die einen Abschnitt mit einem Innengewinde aufweist und die mit ihrem anderen Abschnitt durch radiales Verpressen mit einem Ende des einen Bewehrungsstabes verbunden ist. Das Ende des anderen Bewehrungsstabes besitzt einen Kopf mit einem Außengewinde, wobei der Kopf als zunächst separates Teil, das dann durch Stumpfschweißung am Bewehrungsstab befestigt wird oder als durch Anstauchung umgeformtes Ende ausgeführt sein kann.In DE 196 26 649 A1 a threaded coupling for force-transmitting rods, in particular reinforcing rods for reinforced concrete parts, is described. In this case, a sleeve is provided which has a portion with an internal thread and which is connected to its other portion by radial compression with one end of a reinforcing bar. The end of the other reinforcing bar has a head with an external thread, the head as a first separate part, which is then attached by butt welding to the reinforcing bar or can be designed as an upset by compression end.

Die vorliegende Erfindung geht von der US-A-5,131,204 aus und ihr liegt die Aufgabe zugrunde, eine Schraubverbindung für kraftübertragende Stäbe, insbesondere Bewehrungsstäbe, zu schaffen, die einfacher und kostengünstiger herzustellen ist.The present invention is based on US-A-5,131,204 and its object is a screw connection for force-transmitting rods, in particular Reinforcing bars to create, which is easier and cheaper to produce.

Diese Aufgabe wird durch eine Schraubverbindung für kraftübertragende Stäbe mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a screw connection for force-transmitting rods with the features of claim 1.

Bei der erfindungsgemäßen Schraubverbindung kann das Gewinde unmittelbar an dem Ende des zweiten Stabes aufgerollt werden, ohne daß eine vorherige Bearbeitung des Stabendes erforderlich ist. Der konische Verlauf des Innengewindes innerhalb der Kupplungsmuffe, zumindest über eine Teillänge, führt zu einer Reduzierung des Gewindedurchmessers, was den Vorteil hat, daß die Muffe insgesamt ein kleineres Volumen aufweist und somit auch ein geringeres Volumen am Ende des ersten Stabes umgeformt werden muß. Dadurch werden die Bearbeitungsschritte zur Herstellung der Schraubverbindung vereinfacht, ohne die Schraubverbindung hinsichtlich der Kraftübertragung zu schwächen.In the screw connection according to the invention, the thread can be rolled up directly at the end of the second rod, without any previous processing of the rod end is required. The conical course of the internal thread within the coupling sleeve, at least over a partial length, leads to a reduction of the thread diameter, which has the advantage that the sleeve has a smaller overall volume and thus a smaller volume at the end of the first rod must be transformed. As a result, the processing steps for producing the screw connection are simplified, without weakening the screw connection with respect to the power transmission.

Als besonders zweckmäßig wird angesehen, daß das Außengewinde am Anschlußkopf zumindest über eine Teillänge einen gegenüber dem Durchmesser des zweiten Stabes geringeren Außendurchmesser aufweist. Dabei ist es zweckmäßig, daß das Außengewinde an seinem zum zweiten Stab verlaufenden Übergangsbereich die gleiche Konusform besitzt, wie der konische Gewindeabschnitt am äußeren Ende der Muffe.It is considered particularly expedient that the external thread on the connection head has a smaller outer diameter than the diameter of the second rod, at least over a partial length. It is expedient that the external thread on its extending to the second rod transition region has the same cone shape, as the conical threaded portion at the outer end of the sleeve.

Gemäß der Erfindung ist der Außendurchmesser des Gewindes über eine Teillänge konstant. Als zweckmäßig hat sich eine Gestaltung des Gewindes erwiesen, bei der die Teillänge des konischen Abschnitts das 0,15- bis 0,3-fache der Gesamtlänge des Gewindes beträgt. Eine den geforderten Zugbeanspruchungen gerecht werdende Kraftübertragung wird selbst dann gewährleistet, wenn der Außendurchmesser des Außengewindes geringer ist als der Durchmesser des zweiten Stabes selbst. In weiterer Ausgestaltung der Erfindung wird daher als zweckmäßig angesehen, daß der Außendurchmesser des Außengewindes etwa das 0,9-fache des Durchmessers des zweiten Stabes beträgt.According to the invention, the outer diameter of the thread is constant over a partial length. As appropriate, a design of the thread has proven, in which the partial length of the conical section is 0.15 to 0.3 times the total length of the thread. A force transmission which meets the required tensile stresses is ensured even if the outer diameter of the outer thread is smaller than the diameter of the second rod itself. In a further embodiment of the invention, it is therefore considered expedient that the outer diameter of the outer thread be approximately 0.9 times the diameter of the second rod is.

In Fig. 1 ist das Ende eines ersten Stabes 2 gezeigt, das durch Schmieden im Durchmesser erweitert und als Kupplungsmuffe 4 ausgeführt ist. Diese Kupplungsmuffe 4 umfaßt eine Bohrung 5 mit einem Innengewinde 6, wobei zu dem offenen Ende der Bohrung 5 hin ein konischer Gewindeabschnitt 7 vorgesehen ist. Das vordere Ende der Kupplungsmuffe 4 ist als Flansch 8 gestaltet, in dem sich Bohrungen 9 befinden, die beispielsweise zum Durchtritt von Befestigungsmitteln an einer Schalung dienen. Das Innengewinde 6 hat eine Gesamtlänge 1, wobei das Innengewinde 6 über eine Teillänge l1 einen konstanten Durchmesser aufweist, wohingegen der konische Gewindeabschnitt 7 sich über die wesentlich kürzere Teillänge l2 erstreckt.In Fig. 1 the end of a first rod 2 is shown, which is expanded by forging in diameter and designed as a coupling sleeve 4. This coupling sleeve 4 comprises a bore 5 with an internal thread 6, wherein to the open end of the bore 5 through a conical threaded portion 7 is provided. The front end of the coupling sleeve 4 is designed as a flange 8, in which are bores 9, which serve for example for the passage of fastening means on a formwork. The internal thread 6 has an overall length 1, wherein the internal thread 6 over a partial length l 1 has a constant diameter, whereas the conical threaded portion 7 extends over the much shorter part length l 2 .

Die Fig. 2 zeigt die Ansicht gemäß Pfeil II in Fig. 1, d.h. die Vorderansicht des Flansches 8 mit der zentrisch angeordneten Bohrung 5 sowie Innengewinde 6 und konischem Gewindeabschnitt 7 und vier gleichmäßig über den Umfang verteilt angeordneten Bohrungen 9.Fig. 2 shows the view according to arrow II in Fig. 1, i. the front view of the flange 8 with the centrally disposed bore 5 and internal thread 6 and conical threaded portion 7 and four evenly distributed over the circumference arranged holes 9th

Die Fig. 3 zeigt einen Schnitt durch die Kupplungsmuffe 2 gemäß Fig. 1 sowie zusätzlich einen an einem zweiten Stab 3 ausgeführten Anschlußkopf 10 mit Außengewinde 11. Dieses Außengewinde 11 weist einen Übergangsbereich 12 zu dem zweiten Stab 3 hin auf. Wie aus Fig. 3 weiter ersichtlich ist, besitzt das Außengewinde 11 eine Teillänge l1 mit einem Außendurchmesser DG, der geringer ist als der Durchmesser D des zweiten Stabes 3. Im gezeigten Ausführungsbeispiel beträgt der Außendurchmesser DG des Außengewindes 11 des 0,9-fache des Durchmessers D des zweiten Stabes 3. Sowohl bezüglich der in Fig. 1 gezeigten Teillängen l1 und l2 als auch der in Fig. 3 gezeigten Teillängen l1 und l2 des Anschlußkopfes beträgt die Teillänge l2 das 0,15- bis 0,3-fache der Gesamtlänge 1 des Gewindes.Fig. 3 shows a section through the coupling sleeve 2 according to FIG. 1 and in addition a running on a second rod 3 connecting head 10 with external thread 11. This external thread 11 has a transition region 12 to the second rod 3 out. As is further apparent from Fig. 3, the external thread 11 has a partial length l 1 with an outer diameter D G , which is smaller than the diameter D of the second rod 3. In the embodiment shown, the outer diameter D G of the external thread 11 is 0.9 times the diameter D of the second rod 3. Both with respect to the partial lengths l 1 and l 2 shown in FIG. 1 and the partial lengths shown in FIG. 3 l 1 and l 2 of the connection head, the partial length l 2 is 0.15 to 0.3 times the total length 1 of the thread.

Fig. 4 zeigt eine durch Einschrauben des Anschlußkopfes 10 in die Kupplungsmuffe 4 erzeugte Schraubverbindung 1 für die kraftübertragenden ersten und zweiten Stäbe 2, 3. Da der konische Gewindeabschnitt 7 in der Kupplungsmuffe 4 die gleiche Kontur besitzt wie das konische Gewinde im Übergangsbereich 12, ist eine sehr günstige Kraftübertragung erreicht.4 shows a screw connection 1 produced by screwing in the connection head 10 into the coupling sleeve 4 for the force-transmitting first and second rods 2, 3. Since the conical threaded portion 7 in the coupling sleeve 4 has the same contour as the conical thread in the transitional region 12 achieved a very favorable power transmission.

Die Fig. 5 zeigt eine alternative Ausgestaltung der Kupplungsmuffe 4 am ersten Stab 2, wobei diese Kupplungsmuffe 4 am vorderen Ende mit einem kleineren Flansch 13 versehen ist als in der zuvor beschriebenen Ausführungsform.Fig. 5 shows an alternative embodiment of the coupling sleeve 4 on the first rod 2, said coupling sleeve 4 is provided at the front end with a smaller flange 13 than in the embodiment described above.

Die Fig. 6 zeigt eine Ansicht in Richtung des Pfeiles VI in Fig. 5. Durch den kleineren Flansch 13 der Kupplungsmuffe 4 ist die erforderliche Materialverformung geringer.Fig. 6 shows a view in the direction of arrow VI in Fig. 5. Due to the smaller flange 13 of the coupling sleeve 4, the required material deformation is lower.
