If it has the larger diameter, the compression takes place after the anchor bolt is fastened in the rail, the existence of the intermediate section 8, in particular with the step 17, also being advantageous.

Abstract

An anchor channel for use in the construction industry is provided having outwardly directed protuberances in the web of the channel with openings therethrough which are penetrated by the shaft of an anchor bolt. The bevel of the countersunk head of the anchor bolt is fitted tightly in the protuberance the inner surface of which due to material deformation is attached by a press fit to the circumferential surface of the anchor bolt. The inner surface of the opening is the shape of a truncated cone and arranged with the smaller diameter directed toward the web of the channel. The thereby formed wedge between the surface of the opening and the anchor bolt is filled by squeezing or upsetting a connecting section of the anchor bolt which has a greater cross-section or diameter and projects along the anchor bolt shaft from the countersunk head of the anchor bolt.

Description

Die Erfindung betrifft eine Ankerschiene für die Bautechnik, mit auf dem Schienenrücken aufwärts gerichteten Ausformungen, in denen Öffnungen vorgesehen sind, die vom Schaft eines Ankerbolzens durch­griffen sind, welch letzterer mit seiner Senkkopfschräge passend in der Ausformung einliegt, und deren Innenfläche zufolge Materialver­formung im Preßsitz liegt zur Mantelfläche des Ankerbolzens.The invention relates to an anchor rail for construction engineering, with upward-directed formations on the rail back, in which openings are provided which are penetrated by the shaft of an anchor bolt, the latter of which lies with its countersunk head fitting in the form, and the inner surface of which lies in the press fit due to material deformation to the outer surface of the anchor bolt.

Eine derartige Ausgestaltung ist bekannt aus der DE-PS 3 407 801, wobei der Ankerbolzen als Senkkopfschraube ausgestaltet ist mit über den gesamten Schaft reichendem Außengewinde. Die Ausformung setzt sich dabei in einen auswärts gerichteten Hals fort, welcher im An­schluß an den Senkkopf auf den Schaft aufgepreßt ist. Dieser Bau­form mangelt es an der genügenden Stabilität. Die Übergangsstelle zwischen dem Senkkopf und Schaft ist die am meisten bruchgefährdete. Die Erzeugung eines genügend materialstarken Halses ist umformtech­nisch sehr schwierig. Die Sicherung der Anlagestellung der Kopfschrä­ge zur Ausformung ist während des Verpressens des Halses nur mit erheblichem Aufwand gewährleistet.Such an embodiment is known from DE-PS 3 407 801, the anchor bolt being designed as a countersunk screw with an external thread extending over the entire shaft. The shape continues in an outward-facing neck, which is pressed onto the shaft following the countersunk head. This design lacks sufficient stability. The transition point between the countersunk head and the shaft is the most vulnerable to breakage. The creation of a sufficiently strong neck is very difficult from a forming point of view. Securing the position of the head slope for shaping is ensured only with considerable effort during the pressing of the neck.

Desweiteren ist eine Bauform bekannt, bei welcher das Ankerelement etwa Doppel-T-förmig gestaltet ist. Von dem dem Schienenrücken zu­gekehrten Auflageschenkel des Ankerelements geht ein konisch gestal­tetes Einsteckende aus. Dieses durchgreift die Öffnung und wird dann gestaucht. Das Stirnende wird dabei nietartig zu einem Kopf verformt, der im wesentlichen in der Ausdrückung versenkt einliegt. Es läßt sich jedoch nicht vermeiden, daß nach dem Nietvorgang eine gewisse Rückverformung auftritt, was die Befestigungsstabilität des Ankerbolzens an der Ankerschiene mindert.Furthermore, a design is known in which the anchor element is approximately double T-shaped. A conical insertion end extends from the support leg of the anchor element facing the rail back. This passes through the opening and is then compressed. The front end is deformed into a rivet-like head, which lies substantially recessed in the expression. However, it cannot be avoided that after the riveting process certain recovery occurs, which reduces the stability of the anchor bolt on the anchor rail.

Dem Gegenstand der Erfindung liegt die Aufgabe zugrunde, eine Ankerschiene der in Rede stehenden Art in herstellungstechnisch einfacher Weise so auszugestalten, daß neben einer äußerst stabilen Festlegung der Ankerbolzen an der Ankerschiene keine die Belastbar­keit mindernde Bruchzone im Bereich der Übergangsstelle zwischen Senkkopfschräge und Schaft auftritt.The object of the invention is based on the task of designing an anchor rail of the type in question in a technically simple manner in such a way that, in addition to an extremely stable fixing of the anchor bolts on the anchor rail, there is no breaking zone in the region of the transition point between countersunk bevel and shaft which reduces the load capacity.

Gelöst wird diese Aufgabe durch das Kennzeichen des Anspruchs 1.This problem is solved by the characterizing part of claim 1.

Die Unteransprüche stellen vorteilhafte Weiterbildungen dar.The subclaims represent advantageous developments.

Zufolge derartiger Ausgestaltung ist eine gattungsgemäße Ankerschiene angegeben, die sich durch eine große Haltbarkeit und Stabilität aus­zeichnet. Der nach der erfindungsgemäßen Lehre erzielte Formschluß zwischen Ankerbolzen und Ankerschiene ist optimal, so daß höchste Belastungen schadfrei aufgefangen werden. Erstmals wird ein von einem Senkkopf ausgehender Zwischenabschnitt so vernietet, daß bei diesem Vorgang der Zwickel zwischen Öffnungsinnenfläche und Zwi­schenabschnitt vollständig ausgefüllt wird. Insbesondere läßt sich dieses im Wege des Kaltstauchens vornehmen, wobei der sich an den Senkkopf anschließende, Zwischenabschnitt zu einer gleichmäßigen höheren Festigkeit im Bereich der Übergangsstelle zwischen Senkkopf­schräge und Zwischenabschnitt führt, was mit Sicherheit dort eine bruchbegünstigte Zone ausschließt. Die entsprechende Querschnitts­form der Öffnung führt dazu, daß keine Rückverformung auftritt, die ein etwaiges Lösen des Ankerbolzens begünstigen würde. Der Stauch­druck setzt sich dabei bis in die Ausformung fort unter Erzielung einer engen Anlage der Ausformung an der Senkkopfschräge. Diese Verbindung ist sogar flüssigkeitsdicht. Haarrisse können nicht auf­treten, die einen Durchtritt von Feuchtigkeit zulassen würden. Um die entsprechende kegelstumpfförmige Ausrichtung der Öffnungsinnen­ fläche zu erhalten, ist es möglich, zuerst im Schienenrücken die Öff­nung zu stanzen bzw. zu bohren. Durch das anschließende Drücken der Ausformung erhält die Öffnungsinnenfläche ihre kegelstumpfförmige Ausrichtung. Dieses führt zu einer Herstellungsvereinfachung verbun­den mit verringerten Herstellungskosten. Durch eine entsprechend größere Materialdehnung auf der Außenseite der Ausformung bricht das Loch beim Stanzen kegelstumpfförmig aus. Auch kann die Öffnung noch zwischen der Ausformung gestanzt sein. Es empfiehlt sich dabei, jede Ausformung aus mehreren winklig aneinanderanschließenden Ein­zelabschnitten zusammenzusetzen. Der zentrale Einzelabschnitt dient zur Aufnahme der Senkkopfschräge, während der bzw. die sich an­schließenden Einzelabschnitte zu einer Versteifung des Schienenrückens führen zwecks Erhöhung der Belastungsstabilität und Verringerung auftretender Verformungen unter Belastung. Insbesondere trägt hierzu die Maßnahme bei, einen zum Schieneninneren hin brückenförmig durch­gewölbten Ausformungs-Einzelabschnitt beiderseits des Senkkopf-­Aufnahmeraumes vorzusehen. Damit u. a. auch eine stabile Lage­sicherung des Ankerbolzens beim Vorgang des Gewindewalzens ge­währleistet ist, ist er im Bereich seines freien Endes mit zwei Ge­windeabschnitten ausgestattet, die zwischen sich einen gewindefreien Bolzenabschnitt belassen. Hierdurch wird eine Doppelfunktion er­reicht. Einerseits lassen sich die Gewindeabschnitte günstiger her­stellen. Andererseits dienen diese Gewindeabschnitte zur Halterung einer Mutter, welche sich an den beiden Gewindeabschnitten kontert und dadurch drehgesichert wird. Ein weiterer Vorteil ist darin zu sehen, daß der Kern-Durchmesser im Gewindebereich kleiner ist als im Bereich des Zwischenabschnitts. Dies führt zu einer Vereinfachung der Herstellung. Schließlich ist es belastungstechnisch noch vorteil­haft, daß die Öffnungsinnenfläche etwa senkrecht steht zur Kegel­stumpfmantelfläche des Senkkopfes, d. h., der Senkkopfschräge. Der äußere Gewindeabschnitt braucht nur wenig größer zu sein als die Höhe einer entsprechenden Mutter. Er kann evtl. sogar länger als deren Höhe sein.As a result of such a design, a generic anchor rail is specified which is distinguished by great durability and stability. The positive connection between anchor bolt and anchor rail achieved according to the teaching of the invention is optimal, so that the highest loads are absorbed without damage. For the first time, an intermediate section starting from a countersunk head is riveted in such a way that the gusset between the inner opening surface and the intermediate section is completely filled in this process. In particular, this can be carried out by cold upsetting, the intermediate section adjoining the countersunk head leading to a uniformly higher strength in the region of the transition point between the countersunk head slope and the intermediate section, which certainly precludes a break-prone zone there. The corresponding cross-sectional shape of the opening means that no reshaping occurs, which would favor any loosening of the anchor bolt. The upsetting pressure continues into the formation, achieving a tight fit of the formation on the countersunk bevel. This connection is even liquid-tight. Hairline cracks cannot occur that would allow moisture to pass through. To the corresponding frustoconical orientation of the inside of the opening To preserve the surface, it is first possible to punch or drill the opening in the back of the rail. The inner surface of the opening gets its truncated cone shape by subsequently pressing the shape. This leads to a simplification of production combined with reduced production costs. Due to a correspondingly larger material expansion on the outside of the formation, the hole breaks out in the shape of a truncated cone during punching. The opening can also be punched between the shape. It is advisable to assemble each shape from several individual sections that adjoin one another at an angle. The central individual section serves to accommodate the countersunk head slope, while the subsequent individual section or sections lead to a stiffening of the rail back in order to increase the load stability and reduce deformations occurring under load. In particular, the measure contributes to this by providing a single shaping section that is arched in a bridge shape towards the inside of the rail on both sides of the countersunk head receiving space. So that, among other things, a stable positional securing of the anchor bolt is ensured during the thread rolling process, it is equipped in the region of its free end with two threaded sections, which leave a thread-free bolt section between them. This achieves a double function. On the one hand, the threaded sections can be manufactured more cheaply. On the other hand, these threaded sections serve to hold a nut which is countered on the two threaded sections and is thereby secured against rotation. Another advantage is the fact that the core diameter is smaller in the thread area than in the area of the intermediate section. This leads to a simplification of manufacture. Finally, it is also advantageous in terms of load technology that the inner surface of the opening is approximately perpendicular to the truncated cone surface of the countersunk head, ie the countersunk bevel. The outer threaded section need only be a little larger than the height of a corresponding nut. It may even be longer than their height.

Two embodiments of the invention are shown in the drawing. It shows
  • 1 is a perspective view of the anchor rail with the anchor bolts attached to it, relating to the first embodiment,
  • 2 shows the section along the line II-II in Fig. 1,
  • 3 shows a representation corresponding to FIG. 2, the anchor bolt being inserted but not yet riveted,

  • 4a a variant of this,
  • Fig. 5 shows the section along the line VV in Fig. 4 and

Die Ankerschiene 1 besitzt im Querschnitt ein C-Profil. Im einzelnen besteht die Ankerschiene aus dem Schienenrücken 2, den rechtwinklig von diesem ausgehenden C-Schenkeln 3, an welche sich einwärts abge­winkelte, gegeneinander gerichtete Endabschnitte 4 anschließen. Letztere belassen zwischen sich einen Längsschlitz 5 zum Einführen nicht dargestellter Befestigungselemente.The anchor rail 1 has a C-profile in cross section. In detail, the anchor rail consists of the rail back 2, the C-legs 3 extending at right angles from this, to which inward angled, mutually directed end sections 4 are connected. The latter leave a longitudinal slot 5 between them for inserting fastening elements, not shown.

Von dem Schienenrücken 2 gehen in vorgegebenem Abstand zueinander angeordnete Ankerbolzen 6 aus. Jeder Ankerbolzen 6 bildet eine Senkkopf 7 aus. An letzterem schließt sich ein Zwischenabschnitt 8 an, der sich in einen querschnittsabgesetzten Schaft 9 fortsetzt. Die Länge x des gegenüber dem Schaft 9 querschnittsgrößeren Zwischen­abschnitts 8 ist etwa doppelt so groß wie die Dicke y der Wandstärke der Ankerschiene.Anchor bolts 6 arranged at a predetermined distance from one another extend from the rail back 2. Each anchor bolt 6 forms a countersunk head 7. An intermediate section 8 adjoins the latter and continues into a shaft 9 with a cross-section. The Length x of the intermediate section 8, which is larger in cross-section than the shaft 9, is approximately twice the thickness y of the wall thickness of the anchor rail.

Der Ankerbolzen 6 ist im Bereich seines freien Endes mit zwei hinter­einanderliegenden Gewindeabschnitten 10 und 11 ausgestattet, die zwischen sich einen gewindefreien Bolzenabschnitt 12 belassen. Der endseitige Gewindeabschnitt 10 ist kürzer als der vorgeordnete Ge­windeabschnitt 11 und trägt die Ankermutter M. Der Durchmesser des Bolzenabschnitts 12 entspricht dabei dem Durchmesser des Schaftes 9. Das bedeutet, daß die Gewindeabschnitte 10, 11 einen größeren Durch­messer haben als der Schaft 9. Der Kern-Durchmesser der Gewindeab­schnitte 10, 11 ist jedoch kleiner als derjenige des Bolzenabschnitts 12. Auf den Gewindeabschnitt 10 kann eine Mutter M aufgedreht werden, die dann in Konterstellung zum Abschnitt 12 oder evtl. zu dem Gewinde des Abschnittes 11 tritt oder einer dortigen Konter­mutter.The anchor bolt 6 is equipped in the region of its free end with two thread sections 10 and 11 lying one behind the other, which leave a thread-free bolt section 12 between them. The end threaded section 10 is shorter than the upstream threaded section 11 and carries the anchor nut M. The diameter of the bolt section 12 corresponds to the diameter of the shaft 9. This means that the threaded sections 10, 11 have a larger diameter than the shaft 9. The core The diameter of the threaded sections 10, 11 is, however, smaller than that of the bolt section 12. A nut M can be screwed onto the threaded section 10, which nut then comes into counter position to section 12 or possibly to the thread of section 11 or a lock nut there.

Zur Festlegung der Ankerbolzen 6 bildet die Ankerschiene 1 auf dem Schienenrücken 2 aufwärts gerichtete Ausformungen 13 aus, welche zentral mit einer Öffnung 14 ausgestattet sind.To fix the anchor bolts 6, the anchor rail 1 forms upward-directed formations 13 on the rail back 2, which are provided centrally with an opening 14.

Gemäß den Fig. 1 bis 3 setzt sich jede Ausformung aus drei winklig aneinanderanschließenden Einzelabschnitten 13ʹ, 13ʺ und 13‴ zusam­men. Sie erstrecken sich dabei bei einer besonders zweckmäßigen Ausführungsform in konzentrischer Anordnung. Der mittlere Einzel­abschnitt 13ʺ liegt dabei jenseits des Kopf-Aufnahmeraums 15 und verläuft etwa parallel zum Schieneninneren. Das bedeutet, daß sein Scheitel S die Höhlung H des randseitigen Einzelabschnitts 13‴ auf einer etwas höher als die Schienenrückeninnenfläche leigenden Ebene begrenzt.1 to 3, each shape is composed of three angularly adjoining individual sections 13ʺ, 13ʺ and 13 ‴. In a particularly expedient embodiment, they extend in a concentric arrangement. The middle individual section 13ʺ lies beyond the head receiving space 15 and runs approximately parallel to the interior of the rail. This means that its apex S limits the concavity H of the edge-side individual section 13 ‴ on a plane that is slightly higher than the inner surface of the rail back.

Die Öffnung 14 ist nach dem Herstellen der Ausformung 13 durch Stanzen vom Schieneninneren her erzeugt. Es liegt eine kegelstumpf­ förmig ausgerichtete Öffnungsinnenfläche 14ʹ vor derart, daß der größere Durchmesser zum Schienenrückenäußeren hin weist. Der kleinere Durchmesser der Öffnung 14 entspricht etwa dem Außen­durchmesser des Zwischenabschnitts 8. Wird nun der Ankerbolzen 6 vom Schieneninneren her eingesetzt, so durchgreift der Zwischenab­schnitt 8 die Öffnung 14, während die Senkkopfschräge 7ʹ in Anlage­stellung zur Innenwand des zentralen Einzelabschnitts 13ʹ gelangt. Auf diese Weise wird zwischen der Öffnungsinnenfläche 14ʹ und Zwi­schenabschnitt 8 ein ringförmig umlaufender Zwickel 16 gebildet, der durch anschließendes Stauchen des Zwischenabschnitts 8 ausgefüllt ist, vergl. insbesondere Fig. 2. Das entsprechende, nicht dargestellte Stauchwerkzeug greift dabei an der Stufe 17 zwischen Schaft 9 und Zwischenabschnitt 8 an. Durch den Stauchvorgang tritt eine Gefüge­verdichtung ein. Die Länge des Zwischenabschnitts 8 verkürzt sich einhergehend. Gleichzeitig wird der Zwickel 16 ausgefüllt unter Er­zielung einer stabilen formschlüssigen Halterung des Ankerbolzens 6 an der Ankerschiene 1 im Preßsitz. Der Stauchdruck setzt sich bis in die Wandung der Öffnung 14 fort und bewirkt eine dichte Anlage des ent­sprechenden Bereichs des Zwischenabschnitts 8 an der Öffnungsinnen­fläche 14ʹ. Aus Fig. 2 ist zu ersehen, daß die Öffnungsinnenfläche 14ʹ etwa senkrecht steht zur Kegelstumpfmantelfläche, d. h. Schräge 7ʹ, des Senkkopfes 7.After the formation 13 has been produced, the opening 14 is produced by punching from the inside of the rail. There is a truncated cone shaped inner opening surface 14ʹ in front such that the larger diameter points towards the back of the rail. The smaller diameter of the opening 14 corresponds approximately to the outer diameter of the intermediate section 8. If the anchor bolt 6 is now inserted from the inside of the rail, the intermediate section 8 passes through the opening 14, while the countersunk bevel 7 'comes into contact with the inner wall of the central individual section 13'. In this way, an annular gusset 16 is formed between the opening inner surface 14ʹ and the intermediate section 8, which is filled by subsequent upsetting of the intermediate section 8, see in particular FIG. 2. The corresponding upsetting tool, not shown, engages the step 17 between the shaft 9 and intermediate section 8. The compression process results in a structural compression. The length of the intermediate section 8 is shortened. At the same time, the gusset 16 is filled in to achieve a stable, form-fitting retention of the anchor bolt 6 on the anchor rail 1 in a press fit. The upsetting pressure continues into the wall of the opening 14 and causes the corresponding area of the intermediate section 8 to bear tightly against the opening inner surface 14ʹ. From Fig. 2 it can be seen that the inner opening surface 14ʹ is approximately perpendicular to the truncated cone surface, ie slope 7ʹ, of the countersunk head 7th

Gemäß der in den Fig. 4 bis 6 dargestellten zweiten Ausführungsform ist der Ankerbolzen 6 unverändert gestaltet. Dagegen weist die Aus­formung 18 ein abweichend geformtes Querschnittsprofil auf. Sie besitzt einen zentralen Ausformungs-Einzelabschnitt 18ʹ mit der Öff­nung 14. Beiderseits des Senkkopf-Aufnahmeraumes 15 erstrecken sich zum Schieneninneren hin brückenförmig durchgewölbte Ausfor­mungsabschnitte 18ʺ, die in auswärts gewölbte Einzelabschnitte 18‴, übergehen. Auch durch diese Querschnittsprofilierung wird eine Ver­steifung im Bereich der Ausformung 18 erreicht, so daß der an dem Schienenrücken 2 festgelegte Ankerbolzen eine Lagenstabilisierung er­ fährt. Das Festlegen der Ankerbolzen geschieht in der vorbeschrie­benen Weise.According to the second embodiment shown in FIGS. 4 to 6, the anchor bolt 6 is designed unchanged. In contrast, the formation 18 has a differently shaped cross-sectional profile. It has a central single shaping section 18ʹ with the opening 14. Both sides of the countersunk receiving space 15 extend towards the inside of the rail and are shaped in the form of bridging sections 18ücken which merge into outwardly curved single sections 18‴. This cross-sectional profiling also results in stiffening in the region of the formation 18, so that the anchor bolt fixed to the rail back 2 stabilizes the position moves. The anchor bolts are fixed in the manner described above.

Fig. 4 und Fig. 4a unterscheiden sich dadurch, daß in Fig. 4a die Einzelabschnitte 18‴ Teilbereiche einer Gesamtausführung sind, so daß auf etwa ganzer Ausfomungsbreite die brückenförmige Durchwölbung auftritt und nicht nur in der Ankerbolzen-Längsschnittebene.Fig. 4 and Fig. 4a differ in that in Fig. 4a the individual sections 18 ‴ are partial areas of an overall design, so that the bridge-shaped arching occurs over approximately the entire width of the shape and not only in the longitudinal section of the anchor bolt.

Alternativ zu den mit Muttern versehenen Gewindeabschnitten kann der Ankerbolzen an seinem freien Ende mit einem angestauchten Ankerkopf versehen sein. Der angestauchte Ankerkopf, der einen größeren Querschnitt als der Schaft besitzt, erfüllt dieselbe Aufgabe, nämlich Bildung eines Widerlagers gegenüber dem Einbettungsmaterial für die Ankerschiene, und ist kostengüntiger herstellbar. Hat er den größe­ren Durchmesser, so erfolgt die Anstauchung nach Befestigung des Ankerbolzens in der Schiene, wobei die Existenz des Zwischenabschnit­tes 8, insbesondere mit der Stufe 17, ebenfalls vorteilhaft ist.As an alternative to the threaded sections provided with nuts, the anchor bolt can be provided with an upset anchor head at its free end. The upset anchor head, which has a larger cross section than the shaft, fulfills the same task, namely forming an abutment with respect to the embedding material for the anchor rail, and is less expensive to produce. If it has the larger diameter, the compression takes place after the anchor bolt is fastened in the rail, the existence of the intermediate section 8, in particular with the step 17, also being advantageous.

Alle in der Beschreibung erwähnten und in der Zeichnung dargestell­ten neuen Merkmale sind erfindungswesentlich, auch soweit sie in den Ansprüchen nicht ausdrücklich beansprucht sind.All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
