Abstract
Description
Die Erfindung betrifft einen Adapter zur Anbringung von Positionierungselementen an einer einzubetonierenden Halteschiene, ein Haltesystem mit einem Adapter und einem Positionierungselement sowie ein Haltesystem mit einer einzubetonierenden Halteschiene und einem Adapter.The invention relates to an adapter for mounting positioning elements on a holding rail to be einzubetonierenden, a holding system with an adapter and a positioning element and a holding system with a einzubetonierenden holding rail and an adapter.
Um Bauteile, beispielsweise Fassadenelemente oder Dachaufbauten, an einem Betonbauteil anzubringen, werden Halteschienen verwendet, die teilweise in das Betonbauteil eingegossen sind. Die Halteschienen werden vor dem Betoniervorgang des Betonbauteils an der gewünschten Position an oder in der Verschalung des Betonbauteils angebracht, sodass die Halteschienen beim Einfüllen des flüssigen Betons von diesem teilweise umschlossen werden. Beim Aushärten des Betons entsteht zwischen der Halteschiene bzw. zwischen rückseitig an der Halteschiene vorgesehenen Ankerelementen und dem Betonbauteil eine formschlüssige Verbindung, durch die eine gute Lastübertragung zwischen Halteschiene und Betonbauteil möglich ist. Während des Betonierens muss die Halteschiene sicher in der gewünschten Position gehalten werden, da eine spätere Veränderung der Lage nicht mehr möglich ist.In order to attach components, such as facade elements or roof structures, to a concrete component, retaining rails are used, which are partially cast in the concrete component. The support rails are attached before the concreting of the concrete component at the desired position on or in the casing of the concrete component, so that the support rails are partially enclosed during the filling of the liquid concrete of this. When curing of the concrete is formed between the support rail or between the rear of the support rail provided anchor elements and the concrete component a positive connection through which a good load transfer between support rail and concrete component is possible. During concreting, the retaining rail must be securely held in the desired position, since a subsequent change in position is no longer possible.
Bei geschlossenen Verschalungen, beispielsweise einer Wandverschalung, kann die Halteschiene an der Innenseite der Verschalung befestigt werden, wodurch eine Lageveränderung der Schiene während des Einfüllens des Betons verhindert ist. Bei offenen Verschalungen, beispielsweise für eine Geschossdecke, ist eine solche Anbringung nicht möglich. Die Halteschiene kann aus konstruktiven und statischen Gründen aber auch nicht über die Ankerelemente auf der Bewehrung abgestützt werden. Eine Möglichkeit der Positionierung der Halteschiene besteht in einer Haltevorrichtung, wie sie in der
Aufgabe der Erfindung ist es, eine Positionierungsvorrichtung für eine Halteschiene bereitzustellen, die eine schnelle, individuelle und zuverlässige Positionierung der Halteschiene vor und während des Betoniervorgangs ermöglicht.The object of the invention is to provide a positioning device for a retaining rail, which allows a fast, individual and reliable positioning of the retaining rail before and during the concreting process.
Zur Lösung der Aufgabe ist ein Adapter zur Anbringung von Positionierungselementen an einer einzubetonierenden Halteschiene vorgesehen, wobei der Adapter eine Aufnahme aufweist, in die die Halteschiene eingesetzt werden kann, und mindestens einen Anschluss, mittels dem ein Positionierungselement am Adapter angebracht werden kann. Die Halteschiene wird durch den Adapter, an dem verschiedene Positionierungselemente befestigt werden können, in der vorgegebenen Position gehalten und zusammen mit diesem in den Beton eingegossen. Das Positionierungselement kann aus einer Vielzahl von Positionierungselementen ausgewählt werden, wodurch in Verbindung mit dem Anschluss, der einen schnellen Austausch der Positionierungselemente ermöglicht, eine schnelle und individuelle Anpassung der Position des Adapters und somit der Halteschiene möglich ist. Die Positionierung der Halteschiene erfolgt also vollständig unabhängig von den Ankerelementen der Schiene ausschließlich durch die Auswahl bzw. die Anpassung der Positionierungselemente. Der Adapter kann somit für verschiedene handelsübliche Schienen verwendet werden, ohne weitere Anpassungen an der Halteschiene vornehmen zu müssen. Da der Adapter nicht in die Schiene eingreift, kann diese, um ein Eindringen von Beton zu verhindern, während des Betoniervorgangs abgedeckt bzw. mit einem Schaum oder Styropormaterial gefüllt sein.To solve the problem, an adapter for attaching positioning elements is provided on a einzubetonierenden retaining rail, wherein the adapter has a receptacle into which the retaining rail can be used, and at least one terminal, by means of which a positioning element can be attached to the adapter. The holding rail is held in the predetermined position by the adapter, to which various positioning elements can be attached, and cast together with this in the concrete. The positioning element can be selected from a plurality of positioning elements, which in conjunction with the connection, which allows a quick replacement of the positioning elements, a quick and individual adjustment of the position of the adapter and thus the support rail is possible. The positioning of the retaining rail thus takes place completely independently of the anchor elements of the rail exclusively by the selection or the adaptation of the positioning elements. The adapter can thus be used for various commercially available rails, without having to make any further adjustments to the support rail. Since the adapter does not engage in the rail, it may, in order to prevent ingress of concrete, covered during the concreting process or be filled with a foam or polystyrene material.
Die Aufnahme ist vorzugsweise U-förmig mit einer Basis und zwei Schenkeln ausgebildet, sodass die Halteschiene formschlüssig aufgenommen werden kann. Somit sind an der Schiene keine zusätzlichen Befestigungsmittel notwendig.The receptacle is preferably U-shaped with a base and two legs, so that the holding rail can be received positively. Thus, no additional fastening means are necessary on the rail.
Bei dieser Ausführungsform ist vorzugsweise an der Basis und/oder an einem oder beiden Schenkeln jeweils zumindest ein Anschluss vorgesehen. Der Adapter hat vorzugsweise an zumindest zwei zueinander senkrechten Richtungen einen Anschluss für ein Positionierungselement, wodurch eine Einstellung der Position in zwei zueinander senkrechten Richtungen, beispielsweise in horizontaler und vertikaler Richtung, möglich ist.In this embodiment, at least one connection is preferably provided in each case on the base and / or on one or both legs. The adapter preferably has a connection for a positioning element in at least two mutually perpendicular directions, whereby an adjustment of the position in two mutually perpendicular directions, for example in the horizontal and vertical directions, is possible.
Um die Halteschiene in der Aufnahme zu sichern, kann an zumindest einem Schenkel ein Befestigungselement vorgesehen sein, an dem ein Fixierelement angebracht ist. Das Fixierelement schließt die Aufnahme, wodurch der Adapter die Halteschiene in Umfangsrichtung vollständig umfasst, sodass die Halteschiene vor und während des Betoniervorgangs sicher in der Aufnahme gehalten ist. Nach dem Aushärten des Betons ist die Halteschiene fest in das Betonbauteil eingegossen. Das Fixierelement kann nach dem Betonieren entfernt werden, sodass die Halteschiene über die gesamte Länge ohne Einschränkungen genutzt werden kann.In order to secure the retaining rail in the receptacle, a fastening element can be provided on at least one leg, to which a fixing element is attached. The fixing member closes the receptacle, whereby the adapter completely surrounds the retaining rail in the circumferential direction, so that the retaining rail is securely held in the receptacle before and during the concreting process. After hardening of the concrete, the retaining rail is firmly embedded in the concrete component. The fixing element can be removed after concreting, so that the retaining rail over the entire length can be used without restrictions.
Die Befestigungselemente können beispielsweise Ösen sein und das Fixierelement ein Kabelbinder, der sich durch die beiden Ösen erstreckt. Mit einem solchen Kabelbinder ist ein einfaches Schließen der Aufnahme ohne zusätzliche Werkzeuge möglich. Zudem ist nach dem Betonieren ein einfaches Entfernen des Kabelbinders möglich.The fasteners may be, for example, eyelets and the fixing a cable tie, which extends through the two eyelets. With such a cable tie a simple closing of the recording is possible without additional tools. In addition, a simple removal of the cable tie is possible after concreting.
Die Befestigungselemente können aber auch Haken sein und das Fixierelement ein Deckel, der an den Haken eingehakt ist.But the fasteners may also be hooks and the fixing a lid that is hooked to the hook.
Der Deckel kann auch an einem der Schenkel mit einem Scharnier befestigt sein, sodass dieser unverlierbar am Adapter gehalten ist.The lid can also be attached to one of the legs with a hinge, so that it is held captive on the adapter.
Um das Positionierungselement sicher am Adapter zu befestigen, weist der Anschluss vorzugsweise einen Hinterschnitt auf, insbesondere in der Form einer Nut, einer Schiene, eines Bajonettverschlusses oder eines Gewindes. Diesen Anschlussformen ist gemeinsam, dass sie einen einfachen und schnellen Austausch des Positionierungselements, beispielsweise durch Verschieben, Ausschrauben oder durch Drehen des Positionierungselements, ermöglichen. Zudem ist das Positionierungselement durch den Hinterschnitt in einer Richtung senkrecht zum Anschluss zug- und druckfest am Adapter gehalten.In order to securely fasten the positioning element to the adapter, the connection preferably has an undercut, in particular in the form of a groove, a rail, a bayonet closure or a thread. These connection forms have in common that they allow a simple and quick replacement of the positioning element, for example by moving, unscrewing or by rotating the positioning element. In addition, the positioning element is held by the undercut in a direction perpendicular to the connection tensile and pressure resistant on the adapter.
Des Weiteren ist erfindungsgemäß ein Haltesystem vorgesehen mit einem Adapter nach der vorstehend genannten Art und zumindest einem Positionierungselement, das am Anschluss des Adapters befestigt ist. Das Positionierungselement kann aus einer Vielzahl von verschiedenen vorgefertigten Positionierungselementen ausgewählt werden, wodurch eine spezifische Anpassung an die gewünschte Position der Halteschiene möglich ist.Furthermore, a holding system according to the invention is provided with an adapter according to the aforementioned type and at least one positioning element which is attached to the connection of the adapter. The positioning element can be selected from a variety of different prefabricated positioning elements, whereby a specific adaptation to the desired position of the retaining rail is possible.
Das Positionierungselement ist beispielsweise ein Stab, der als Abstandshalter dienen kann. Der Stab kann sich an der Innenseite der Verschalung oder auch an einem Teil der Bewehrung abstützen. Vorzugsweise steht eine Vielzahl von verschiedenen Stablängen zur Auswahl, um eine schnelle, individuelle Anpassung zu ermöglichen.The positioning element is, for example, a rod which can serve as a spacer. The bar can be supported on the inside of the casing or on a part of the reinforcement. Preferably, a variety of different rod lengths are available for quick, customization.
Alternativ ist es aber auch denkbar, dass der Stab längenverstellbar ist, sodass eine Längenanpassung des Positionierungselements ohne Austausch des Positionierungselements möglich ist.Alternatively, it is also conceivable that the rod is adjustable in length, so that a length adjustment of the positioning element without replacement of the positioning element is possible.
Die Längenverstellung kann aber auch über den Anschluss bzw. ein weiteres Bauteil des Positionierungselements erfolgen. Der Stab kann also auch einstellbar am Adapter angebracht werden, sodass mit einer Stablänge verschiedene Positionierungen möglich sind.The length adjustment can also be done via the connection or another component of the positioning element. The rod can therefore also be adjustably mounted on the adapter, so that different positions are possible with a rod length.
Es ist auch denkbar, dass das Positionierungselement einen Sockel aufweist, mit dem sich der Adapter abstützen kann. Der Sockel bietet eine breitere Aufstandsfläche, sodass sich das Positionierungselement beispielsweise auf einem Teil der Bewehrung abstützen kann.It is also conceivable that the positioning element has a base with which the adapter can be supported. The pedestal provides a wider footprint, allowing the positioning element to rest on, for example, a portion of the rebar.
Der Adapter kann beispielsweise zumindest teilweise aus Kunststoff bestehen. Kunststoff bietet zum einen den Vorteil, dass dieser im ausgehärteten Beton nicht korrodiert, sodass eine spätere Schädigung des Betons ausgeschlossen werden kann. Zum anderen kann Kunststoff auch mit auf einer Baustelle üblichen Werkzeugen bearbeitet werden, sodass eine einfache Anpassung beispielsweise der Länge des Positionierungselements möglich ist.The adapter may, for example, at least partially made of plastic. On the one hand, plastic offers the advantage that it does not corrode in the hardened concrete, so that later damage to the concrete can be ruled out. On the other hand, plastic can also be processed with conventional tools on a construction site, so that a simple adaptation, for example, the length of the positioning element is possible.
Es ist aber auch denkbar, dass das Positionierungselement teilweise aus Beton oder einem zementgebundenen Material besteht. Falls sich das Positionierungselement an einem Verschalungsteil abstützt, entstehen so beispielsweise bei Sichtbeton keine sichtbaren Fehlstellen. Zudem weist das Positionierungselement so die gleichen mechanischen Eigenschaften wie der umgebende Beton auf.However, it is also conceivable that the positioning element consists partly of concrete or a cement-bonded material. If the positioning element is supported on a casing part, no visible defects arise, for example, in exposed concrete. In addition, this indicates Positioning element so on the same mechanical properties as the surrounding concrete.
Des Weiteren ist erfindungsgemäß ein Haltesystem mit einer einzubetonierenden Halteschiene und einem Adapter nach einem der vorhergehenden Ansprüche vorgesehen, wobei die Halteschiene fest im Adapter aufgenommen ist und am Adapter ein ausgewähltes Positionierungselement aus einer Vielzahl von verfügbaren Positionierungselementen angebracht ist.Furthermore, a holding system according to the invention is provided with a holding rail to be einzubetonierenden and an adapter according to one of the preceding claims, wherein the holding rail is firmly received in the adapter and the adapter is a selected positioning of a plurality of available positioning elements attached.

Beim Betonieren des Betonbauteils wird die Halteschiene 50 so in das Betonbauteil eingegossen, dass die Nut auf der Außenseite des Betonbauteil zugänglich ist, um Bauteile, beispielsweise Dachaufbauten, an der Schiene zu befestigen. Durch die Ankerelemente 54 ist die Halteschiene 50 nach dem Aushärten des Betons formschlüssig im Betonbauteil gehalten.When concreting the concrete component, the retaining
Der Adapter 10 hat eine Aufnahme 14, die hier U-förmig mit einer Basis 16 und zwei gegenüberliegenden Schenkeln 18, 20 ausgebildet ist (
Auf der vom Aufnahmeraum 12 abgewandten Außenseite des Adapters 10 ist an der Basis 16 sowie an den Schenkeln 18, 20 jeweils ein Anschluss 36, 38, 40 für ein Positionierungselement vorgesehen. Die Anschlüsse 36, 38, 40 sind hier jeweils als Schiene mit einem schwalbenschwanzförmigen Querschnitt und hinterschnittenen Anschlussflächen 41 ausgebildet.On the side facing away from the receiving
An der dem Aufnahmeraum 12 zugewandten Innenseite der Schenkel 18, 20 ist jeweils ein in Richtung zum Aufnahmeraum 12 weisendes Federelement 42, 44 vorgesehen. Diese können die Halteschiene 50 in der Aufnahme 14 festklemmen, indem sie beim Einsetzen der Halteschiene 50 hinter Verdickungen 53 einrasten, die auf der Außenseite der Halteschiene 50 vorgesehen sind.At the receiving
Wie in
Da jeweils an der Basis 16 und den Schenkeln 18, 20 ein Anschluss 36, 38, 40 vorgesehen ist, kann der Adapter 10 durch entsprechende Positionierungselemente 46 sowohl in horizontaler als auf in vertikaler Position ausgerichtet und gehalten werden. In horizontaler Richtung können sich die Positionierungselemente 46 an der seitlichen Verschalung 82 abstützen, und in vertikaler Richtung ist eine Abstützung an der Bewehrung 86 oder der unteren Verschalung 84 möglich.Since a
Das Positionierungselement 46 weist eine Grundplatte 48 auf, auf der eine Hülse 56 befestigt ist. Auf der gegenüberliegenden Fläche der Grundplatte 48 sind zwei parallel zueinander verlaufende, hinterschnittene Schienen 55 vorgesehen, mit denen das Positionierungselement 46 an den hinterschnittenen Anschlussflächen 41 des Adapter 10 befestigt werden kann. In Längsrichtung der Schienen 55 sind am Rand der Grundplatte 48 zwei Rastelemente 57 vorgesehen, die am Rand des Anschlusses 38 einrasten und das Positionierungselement 46 in Längsrichtung fixieren.The
In die Hülse 56 kann ein Stab 60 eingesetzt werden. Die Länge des Stabes 60 kann so gewählt werden, dass sich der Stab 60 an der Verschalung 80 oder der Bewehrung 86 abstützen kann (
Die Stäbe 60 können in verschiedenen vorgefertigten Längen geliefert werden, sodass jeweils ein Stab 60 mit der passenden Länge ausgewählt werden kann. Es ist aber auch denkbar, dass der Stab 60 vor Ort an die gewünschte Länge angepasst wird oder längenverstellbar ausgebildet ist.The
Am zur Halteschiene 50 entgegengesetzten Ende des Stabes 60 können auch weitere Teile des Positionierungselements 46 angesetzt werden, beispielsweise ein Stützelement 62 oder ein Sockel 64, die jeweils die Auflagefläche des Positionierungselements 46 vergrößern.On the holding

Der Adapter 10 hält während des Betoniervorgangs die Halteschiene 50 in Position, bis der Beton ausreichend ausgehärtet ist. Der Adapter 10 sowie die Positionierungselemente 46, 48 verbleiben im ausgehärteten Beton, übernehmen aber keine lastabtragende Funktion. Die Lastübertragung zwischen Halteschiene und Betonbauteil erfolgt nach dem Aushärten des Betons ausschließlich über Formschluss zwischen dem Betonbauteil und den Ankerelementen 54 bzw. der Halteschiene 50. Der Deckel 22 kann deshalb nach dem Aushärten entfernt werden, um die Nut 52 der Halteschiene 50 über die gesamte Länge nutzen zu können. Da der Adapter 10 nicht in die Halteschiene 50 bzw. in die Nut 52 eingreift, kann die Nut 52 während des Betoniervorgangs abgedeckt werden, um ein Verschmutzen der Nut 52 zu verhindern. Die Nut 52 kann auch beispielsweise mit einem aufgeschäumten Material gefüllt sein, das nach dem Betonieren einfach entfernt werden kann.The
Um eine Korrosion des Adapters 10 oder des Positionierungselements 46 zu vermeiden, sind diese vorzugsweise aus einem Kunststoff gefertigt. Alternativ ist es auch denkbar, dass der Adapter 10 und das Positionierungselement 46 zumindest teilweise aus Beton oder einem anderen zementgebundenen Material bestehen.In order to avoid corrosion of the
Statt der hier gezeigten schienenförmigen Anschlüsse 36, 38, 40 sind auch andere Anschlussarten denkbar. Insbesondere kann der Anschluss 36, 38, 40 beispielsweise in Form eines Bajonettverschlusses oder eines Gewindes ausgebildet sein. In der in
Statt des hier gezeigten Ausführungsform mit einem klappbaren Deckels 22 ist es auch denkbar, das an beiden Schenkeln 18, 20 ein Rasthaken vorgesehen ist, in die der Deckel 22 eingerastet werden kann. Anstelle des Deckels können auch andere geeignete Fixierelemente verwendet werden, um die Aufnahme 14 zu schließen. Statt des Deckels 22 kann beispielsweise ein Kabelbinder 75 verwendet werden, der an jeweils einer an den freien Enden 24, 26 vorgesehenen Öse 66, 68 befestigt ist (
Eine weitere Ausführungsform eines längenverstellbaren Positionierungselements 46 ist in den
