Die Erfindung betrifft ferner eine Schienenanordnung aufweisend eine Profilschiene und eine solche Endkappe, gemäss Anspruch 6, und eine Befestigungsanordnung aufweisend eine solche Schienenanordnung und einen Befestigungsstift, gemäss Anspruch 7. The invention relates to an end cap for a profile rail according to the preamble of claim 1. Such an end cap is formed with a connector for connecting the end cap to the profile rail and with at least one opening, through which a fastening pin for mounting the profile rail, in particular on a formwork, can be passed.

Zum Befestigen von Anbauteilen, beispielsweise Vorhangfassaden, an Betonelementen, sind als Ankerschienen ausgebildete Profilschienen bekannt. Solche Ankerschienen werden häufig an der Schalung des Betonelements fixiert, beispielsweise festgenagelt, und dann im Beton eingegossen. Um ein stirnseitiges Eindringen von Beton in die Ankerschienen zu vermeiden und/oder um ein Widerlager für Befestigungsstifte zum Befestigen der Ankerschienen an der Schalung bereitzustellen, kann eine Ankerschienen eine Endkappe aufweisen. Endkappen für Ankerschienen, insbesondere mit Öffnungen für Befestigungsstifte zum Fixieren der Ankerschienen an einer Schalung, sind beispielsweise aus DE2916005 C2, US2014250825 A1 , DE1814195 U und GB687272 A bekannt. For attaching attachments, such as curtain walls, concrete elements, designed as anchor rails rails are known. Such anchor rails are often fixed to the formwork of the concrete element, for example, nailed down, and then poured into the concrete. In order to avoid a frontal intrusion of concrete into the anchor channels and / or to provide an abutment for attachment pins for attaching the anchor channels to the formwork, an anchor channel may have an end cap. End caps for anchor channels, in particular with openings for fastening pins for fixing the anchor channels to a formwork, are known, for example, from DE2916005 C2, US2014250825 A1, DE1814195 U and GB687272 A.
Aufgabe der Erfindung ist es, eine Endkappe für eine Profilschiene, eine Schienenanordnung aufweisend eine Profilschiene und eine solche Endkappe, und eine Befestigungsanordnung aufweisend eine solche Endkappe, eine Profilschiene und einen Befestigungsstift anzugeben, welche bei geringem Aufwand, insbesondere Herstellungsaufwand, und hoher Zuverlässigkeit eine besonders einfache, präzise und zuverlässige Montage der Profilschiene an einer Schalung ermöglichen. The object of the invention is to provide an end cap for a rail, a rail assembly comprising a rail and such an end cap, and a fastening arrangement comprising such an end cap, a rail and a fixing pin, which at low cost, especially manufacturing cost, and high reliability a particularly enable easy, precise and reliable mounting of the rail on a formwork.
Die Aufgabe wird erfindungsgemäss durch eine Endkappe mit den Merkmalen des Anspruchs 1 , eine Schienenanordnung mit den Merkmalen des Anspruchs 6 und eine Befestigungsanordnung mit den Merkmalen des Anspruchs 7 gelöst. Bevorzugte Ausführungsformen sind in den abhängigen Ansprüchen angegeben. The object is achieved by an end cap with the features of claim 1, a rail assembly with the features of claim 6 and a Fastening arrangement with the features of claim 7 solved. Preferred embodiments are given in the dependent claims.
Eine erfindungsgemässe Endkappe ist dadurch gekennzeichnet, dass die zumindest eine Öffnung der Endkappe eine lokale Querschnittsverengung zum Vorfixieren des Befestigungsstifts in der Öffnung aufweist. An end cap according to the invention is characterized in that the at least one opening of the end cap has a local cross-sectional constriction for prefixing the attachment pin in the opening.
Ein erster Grundgedanke der Erfindung kann darin gesehen werden, eine Einrichtung zum Vorfixieren des Befestigungsstifts, also insbesondere des Nagels, in der Öffnung während der Montage vorzusehen. Diese Einrichtung zum Vorfixieren des Befestigungsstifts hält den Befestigungsstift während der Montage vorläufig an der Profilschiene, und der Befestigungsstift wird automatisch mitsamt der Profilschiene an seine korrekte Position zum Fixieren der Profilschiene an der Schalung verbracht. Insbesondere kann dies in besonders einfacher Weise eine Montage durch nur einen einzigen Monteur, vorzugsweise ohne weitere Hilfsmittel, ermöglichen. Gemäss einem weiteren Grundgedanken der Erfindung wird die Einrichtung zum Vorfixieren des Befestigungsstifts durch eine lokale, das heisst lediglich bereichsweise, Querschnittsverengung in der Öffnung gebildet. Diese Querschnittsverengung kann am Befestigungsstift, insbesondere an dessen Schaft, anliegen und den Befestigungsstift damit gegen ein ungewolltes Lösen bei den während der Montage typischerweise auftretenden Kräften sichern, das heisst die Querschnittsverengung kann den Befestigungsstift vorfixieren. Zugleich kann die durch die Querschnittsverengung bewirkte Vorfixierung hinreichend locker sein, um ein anschliessendes Eintreiben des Befestigungsstifts in die Schalung und damit verbunden eine Bewegung des Befestigungsstifts relativ zur Endkappe zu ermöglichen. Dies kann mittels einer Querschnittsverengung in besonders einfacher und zugleich zuverlässiger Weise gewährleistet werden. A first basic idea of the invention can be seen in providing a device for prefixing the fastening pin, that is to say in particular the nail, in the opening during assembly. This means for pre-fixing the fixing pin provisionally holds the fixing pin to the rail during installation, and the fixing pin is automatically moved together with the rail to its correct position for fixing the rail to the formwork. In particular, this can in a particularly simple manner allow assembly by only a single fitter, preferably without further aids. According to a further basic concept of the invention, the device for prefixing the fastening pin is formed by a local, that is to say only in regions, cross-sectional constriction in the opening. This cross-sectional constriction can rest on the fastening pin, in particular on its shaft, and thus secure the fastening pin against undesired loosening during the forces typically occurring during assembly, that is to say the cross-sectional constriction can pre-fix the fastening pin. At the same time caused by the cross-sectional constriction prefixing may be sufficiently loose to allow subsequent driving of the fixing pin in the formwork and associated movement of the fixing pin relative to the end cap. This can be ensured by means of a cross-sectional constriction in a particularly simple and reliable manner.
Die Endkappe besteht vorzugsweise aus einem Kunststoffmaterial. Der Verbinder kann beispielsweise als Steckverbinder ausgebildet sein. Vorzugsweise kann der Verbinder ein Einsteckverbinder sein, der zum Verbinden der Endkappe mit der Profilschiene in die Profilschiene, vorzugsweise in einen Schienenkörper der Profilschiene, einsteckbar ist. Für eine besonders gute Verbindung mit der Profilschiene, insbesondere durch Erhöhung der Reibung mit der Profilschiene, kann der Verbinder beispielsweise Lamellen aufweisen. The end cap is preferably made of a plastic material. The connector may be formed, for example, as a connector. Preferably, the connector may be a male connector, which is insertable for connecting the end cap with the rail in the rail, preferably in a rail body of the rail. For a particularly good connection with the rail, in particular by increasing the friction with the rail, the connector may for example have lamellae.
Die Öffnung ist insbesondere so angeordnet, dass der Befestigungsstift durch die Öffnung zum Montieren der Profilschiene an einer Schalung hindurchführbar ist, das heisst die Öffnung verläuft zweckmässig senkrecht zur Längserstreckung der Profilschiene, senkrecht zur Längserstreckung des gegebenenfalls vorhandenen Einsteckverbinders und/oder senkrecht zu einer Ebene, welche durch einen Schienenschlitz der Profilschiene aufgespannt wird. The opening is in particular arranged so that the fastening pin can be passed through the opening for mounting the rail on a formwork, that is, the opening extends expediently perpendicular to the longitudinal extension of the rail, vertically to the longitudinal extent of the optional male connector and / or perpendicular to a plane which is spanned by a rail slot of the rail.
Der Befestigungsstift dient insbesondere zum Fixieren der Endkappe und somit der Profilschiene an einer Schalung. Der Befestigungsstift kann ein Nagel, aber auch eine Schraube sein. Der Befestigungsstift weist geeigneterweise einen Kopf und einen Schaft auf, wobei der Kopf zweckmässigerweise zum Halten der Endkappe querschnittsgrösser als die Öffnung ist. Vorzugsweise ist die Querschnittsverengung so ausgebildet, dass die Querschnittsverengung zum Vorfixieren des Befestigungsstifts gegen den Schaft des Befestigungsstifts wirkt. The fastening pin is used in particular for fixing the end cap and thus the profile rail to a formwork. The attachment pin can be a nail, but also a screw. The fixing pin suitably has a head and a shank, the head being expediently larger than the opening for holding the end cap. Preferably, the cross-sectional constriction is formed so that the cross-sectional constriction acts to pre-fix the fastening pin against the shank of the fastening pin.
Die Profilschiene weist zweckmässigerweise einen von Schienenlippen flankierten Schienenschlitz auf, an welchem Hammerkopfelemente, beispielsweise Hammerkopfschrauben, festgelegt werden können. Insbesondere kann die Profilschiene eine Ankerschiene sein. Eine solche Ankerschiene weist zumindest einen Anker auf, der am Schienenkörper der Profilschiene vorsteht. The rail advantageously has a rail slot flanked rail slats on which hammer head elements, such as hammer head screws can be set. In particular, the rail can be an anchor rail. Such an anchor rail has at least one anchor, which protrudes on the rail body of the rail.
Besonders bevorzugt ist es, dass die Querschnittsverengung durch Zungen gebildet ist. Diese Zungen stehen in den Querschnitt der Öffnung vor und bilden somit die Querschnittsverengung. Eine solche Ausgestaltung kann in herstellungstechnisch besonders einfacher Art und Weise realisiert werden und ist zugleich besonders zuverlässig. Vorzugsweise sind die Zungen integral mit der Endkappe ausgestaltet, was die Herstellung, beispielsweise in einem Spritzgussverfahren, noch weiter vereinfachen kann. Vorzugsweise haben die Zungen jeweils die Form eines Kreissektors. It is particularly preferred that the cross-sectional constriction is formed by tongues. These tongues protrude into the cross section of the opening and thus form the cross-sectional constriction. Such a configuration can be realized in manufacturing technology particularly simple manner and is also very reliable. Preferably, the tongues are integral with the end cap, which can further simplify manufacture, for example, in an injection molding process. Preferably, the tongues each have the shape of a circular sector.
Die Öffnung der Endkappe kann insbesondere eine Durchgangsöffnung sein. Es kann auch eine vom Befestigungsstift durchstossbare Membran vorgesehen sein, welche die Öffnung teilweise oder vollständig abschliesst. Diese Membran kann insbesondere eine Schwimmhaut sein, die sich bei der Herstellung in einem Spritzgussverfahren einstellt. Insbesondere kann die Öffnung zylindrisch ausgeführt sein. Die Endkappe umgibt vorzugsweise die Öffnung ringartig. The opening of the end cap may in particular be a passage opening. It is also possible to provide a membrane puncturable by the fastening pin which closes the opening partially or completely. In particular, this membrane can be a flea skin which sets itself up during manufacture in an injection molding process. In particular, the opening may be cylindrical. The end cap preferably surrounds the opening in an annular manner.
Weiterhin ist es besonders vorteilhaft, dass die Querschnittsverengung an einem Ende der Öffnung, insbesondere an einem der Schalung abgewandten Ende der Öffnung, angeordnet ist. Der hierdurch in der Öffnung geschaffene Raum kann eine Deformation der Zungen besonders gut aufnehmen. Darüber hinaus kann der Herstellungsaufwand noch weiter reduziert werden, insbesondere in einem Spritzgussverfahren, da das Entformen erleichtert sein kann. Furthermore, it is particularly advantageous that the cross-sectional constriction is arranged at one end of the opening, in particular on an end of the opening facing away from the formwork. The space created thereby in the opening can absorb a deformation of the tongues particularly well. In addition, the manufacturing cost can be even further be reduced, especially in an injection molding process, since the demolding can be facilitated.
Eine weitere bevorzugte Ausgestaltung der Erfindung liegt darin, dass sie eine Zentrierungsmarkierung zum Zentrieren der Profilschiene aufweist. Diese Zentrierungsmarkierung ist zweckmässigerweise in der Verlängerung des Schienenschlitzes der mit der Endkappe verbundenen Profilschiene angeordnet. Die Zentrierungsmarkierung kann die korrekte Positionierung der Profilschiene bei besonders geringem Herstellungsaufwand noch weiter vereinfachen. Vorzugsweise ist die Zentrierungsmarkierung eine Zentrierungskerbe. Eine solche Zentrierungskerbe ist besonders gut sichtbar und besonders einfach und materialsparend zu fertigen. A further preferred embodiment of the invention is that it has a centering mark for centering the profile rail. This centering mark is expediently arranged in the extension of the rail slot of the profile rail connected to the end cap. The centering mark can further simplify the correct positioning of the profile rail with a particularly low production outlay. Preferably, the centering mark is a centering notch. Such a centering notch is particularly visible and very easy to manufacture and save material.

Die Befestigungsanordnung weist eine Profilschiene 10, zumindest eine Endkappe 30 und zumindest einen Befestigungsstift 60 auf. The fastening arrangement has a profile rail 10, at least one end cap 30 and at least one fastening pin 60.
Die Profilschiene 10 ist zum Eingiessen in Beton vorgesehen und weist einen Schienenkörper 1 1 auf. Die Profilschiene 10 ist als Ankerschiene ausgebildet und weist als solche eine Vielzahl von Ankern 18 auf, die am Schienenkörper 1 1 angeordnet sind. Der Schienenkörper 1 1 ist C-förmig ausgestaltet und weist an seiner Oberseite einen länglichen Schienenschlitz 13 auf, durch den ein Zugang in den Innenraum des Schienenkörpers 1 1 möglich ist. Der Schienenschlitz 13 wird von zwei gegenüberliegenden Schienenlippen 14 begrenzt, an denen eine durch den Schienenschlitz 13 hindurchgeführte Hammerkopfschraube festlegbar ist. Die Anker 18 sind in der dargestellten Ausführungsform auf der dem Schienenschlitz 13 entgegengesetzten Rückseite des Schienenkörpers 1 1 mit Schienenkörper 1 1 verbunden. Grundsätzlich ist aber auch eine andere Anordnung der Ankern 18, zum Beispiel seitlich am Schienenkörper 1 1 , denkbar. The rail 10 is provided for pouring into concrete and has a rail body 1 1. The rail 10 is formed as an anchor rail and has as such a plurality of anchors 18, which are arranged on the rail body 1 1. The rail body 1 1 is designed C-shaped and has on its upper side an elongated rail slot 13 through which access into the interior of the rail body 1 1 is possible. The rail slot 13 is bounded by two opposite rail lips 14, on which a guided through the rail slot 13 hammer head screw can be fixed. The armature 18 are connected in the illustrated embodiment on the rail slot 13 opposite rear side of the rail body 1 1 with rail body 1 1. In principle, however, another arrangement of the anchors 18, for example laterally on the rail body 1 1, conceivable.
Der Schienenkörper 1 1 wird von zwei entgegengesetzt angeordneten Stirnseiten begrenzt, zwischen denen sich der Schienenschlitz 13 erstreckt. Zumindest eine dieser Stirnseiten der Profilschiene 10 ist von einer Endkappe 30 abgeschlossen. Die Endkappe 30 weist einen als Einsteckverbinder ausgestalteten Verbinder 32 auf, der in den Schienenkörper 1 1 eingesteckt ist. Für eine noch bessere Verbindung mit der Profilschiene 10 ist der Verbinder 32 hier beispielhaft mit umlaufenden Kontaktlamellen versehen, die aber auch entfallen können. The rail body 1 1 is bounded by two opposite end faces, between which the rail slot 13 extends. At least one of these end faces of the profile rail 10 is closed by an end cap 30. The end cap 30 has a plug-in connector designed as a connector 32 which is inserted into the rail body 1 1. For an even better connection with the rail 10, the connector 32 here exemplified with rotating contact blades, but can also be omitted.
Die Endkappe 30 weist ferner einen Befestigungsschenkel 33 zum Befestigen des Schienenkörpers 1 1 und somit der Profilschiene 10 an einer Schalung auf. Der Befestigungsschenkel 33 weist eine Kontaktoberfläche 95 für die Schalung auf, die zumindest annähernd in der vom Schienenschlitz 13 und/oder den Schienenlippen 14 aufgespannten Ebene verläuft. The end cap 30 further includes a mounting leg 33 for attaching the rail body 1 1 and thus the rail 10 on a formwork. The fastening leg 33 has a contact surface 95 for the formwork, which extends at least approximately in the plane defined by the rail slot 13 and / or the rail lips 14.
Der Befestigungsstift 60 ist mit einem Schaft 62 und einem im Vergleich zum Schaft 62 querschnittsgrösseren Kopf ausgeführt. Im dargestellten Ausführungsbeispiel ist der Befestigungsstift 60 gewindefrei als Nagel ausgeführt. Er kann aber auch als Schraube ausgestaltet sein. Der Befestigungsstift 60 dient zum Befestigen, insbesondere Festnageln, der Schienenanordnung an der Schalung. The fastening pin 60 is designed with a shaft 62 and a cross-sectionally larger head than the shaft 62. In the illustrated embodiment, the fixing pin 60 is thread-free executed as a nail. But it can also be configured as a screw. The fastening pin 60 is used for fastening, in particular pinning, the rail arrangement on the formwork.
Die Endkappe 30 weist in ihrem Befestigungsschenkel 33 eine Öffnung 40 auf, welche den Befestigungsschenkel 33 der Endkappe 30 von hinten nach vorne durchläuft, welche in die Kontaktoberfläche 95 für die Schalung mündet und/oder welche zum Durchführen des Schafts 62 des Befestigungsstifts 60 vorgesehen ist. Die Öffnung 40 ist querschnittskleiner als der Kopf 61 des Befestigungsstifts 60 ausgebildet, so dass der Kopf 61 den durch die Öffnung 40 hindurchgeführten Befestigungsstift 60 an der Endkappe 30 verankern kann. The end cap 30 has in its mounting leg 33 an opening 40 which passes through the attachment leg 33 of the end cap 30 from back to front, which opens into the contact surface 95 for the formwork and / or which is provided for performing the shaft 62 of the fixing pin 60. The opening 40 is formed smaller in cross section than the head 61 of the fixing pin 60 so that the head 61 can anchor the fixing pin 60 passed through the opening 40 to the end cap 30.
Die Endkappe 30 weist weiterhin vier kreissektorförmige Zungen 42 auf, die am rückwärtigen Ende, das heisst an dem der Kontaktoberfläche 95 für die Schalung angewandten Ende, der Öffnung 40 in die Öffnung 40 vorstehen. Diese Zungen 42 bilden eine flexible lokale Querschnittsverengung 41 , welche den Schaft 62 des Befestigungsstifts 60 während der Montage der Schienenanordnung an der Schalung vorläufig halten kann. The end cap 30 also has four circular sector-shaped tongues 42 which project into the opening 40 at the rear end, that is to say at the end applied to the contact surface 95 for the formwork. These tongues 42 form a flexible local cross-sectional constriction 41 which can provisionally hold the stem 62 of the attachment pin 60 during assembly of the track assembly to the formwork.
Im dargestellten Ausführungsbeispiel weist die Endkappe 30 im Befestigungsschenkel 33 noch zwei weitere Öffnungen 40' für weitere Befestigungsstifte auf (der Übersichtlichkeit halber nur in Figur 2 mit Bezugszeichen versehen), welche in Analogie zur Öffnung 40 ebenfalls mit Zungen zum Bilden einer Querschnittsverengung ausgebildet sind. Die weiteren Öffnungen 40' sind im dargestellten Ausführungsbeispiel beispielhaft querschnittsgrösser als die Öffnung 40 ausgeführt. In the illustrated embodiment, the end cap 30 in the mounting leg 33 still two more openings 40 'for further mounting pins (for clarity, only provided in Figure 2 with reference numerals), which are also formed with tongues for forming a cross-sectional constriction in analogy to the opening 40. The further openings 40 'are in the illustrated embodiment, for example, cross-section larger than the opening 40 executed.
Für eine besonders einfache Positionierung der Schienenanordnung weist die Endkappe 30 eine Zentrierungsmarkierung 38 auf, die in der Verlängerung des Schienenschlitzes 13 angeordnet ist, und die somit eine einfache Positionierung des Schienenschlitzes 13 der Profilschiene 10 ermöglicht. Die Zentrierungsmarkierung 38 ist hier beispielhaft als Kerbe in der Endkappe 30 ausgeführt. For a particularly simple positioning of the rail arrangement, the end cap 30 has a centering marking 38, which in the extension of the rail slot 13 is arranged, and thus allows easy positioning of the rail slot 13 of the rail 10. The centering mark 38 is embodied here by way of example as a notch in the end cap 30.
Für eine besonders robuste, aber auch materialsparende Ausgestaltung weist die Endkappe 30 einen innenseitige Versteifungsverrippung 39 auf. For a particularly robust, but also material-saving embodiment, the end cap 30 on an inside ribbing 39 on.
