Description

Die vorliegende Erfindung betrifft eine Ankerschiene zum Verankern von Hammerkopfschrauben und anderen Befestigungsmitteln an einem Betonteil, mit einem ersten Schienenteil und einem zweiten Schienenteil, die aus Metall hergestellt sind und senkrecht zu ihrer Längsrichtung eine Vielzahl von Ankerstegen aufweisen und einen durch ein Füllungselement ausgefüllten Kanal umschließen, an dem auf der zu den Ankerstegen abgewandten Seite ein Schlitz zur Aufnahme von Befestigungsmitteln ausgebildet ist, wobei integral mit dem ersten und dem zweiten Schienenteil beabstandet von dem Schlitz mehrere Verbindungsstege ausgebildet sind, die miteinander verschweißt sind.The present invention relates to an anchor rail for anchoring T-head bolts and other fasteners to a concrete part, with a first rail part and a second rail part, which are made of metal and have a large number of anchor webs perpendicular to their longitudinal direction and enclose a channel filled with a filling element. on the side facing away from the anchor webs a slot for receiving fastening means is formed, wherein a plurality of connecting webs are formed integrally with the first and the second rail part at a distance from the slot, which are welded to one another.

Die EP 3 081 707 A1 offenbart eine Ankerschiene zur Verankerung in Beton, um Schrauben zu befestigen, insbesondere Hammerkopfschrauben. Die Ankerschiene ist als U-förmiges Profil mit nach innen gerichteten Stegen an den beiden Schenkeln ausgebildet, um die Hammerkopfschrauben zu fixieren. An der Schiene sind mehrere Anker fixiert, die der Schiene nach dem Eingießen in Beton Halt geben sollen. Die Herstellung der Ankerschiene mit den separat angebrachten stiftförmigen Ankern ist vergleichsweise aufwändig und erfordert eine Vielzahl von separat hergestellten Bauteilen. Zudem sind die Verbindungsstellen zwischen den Ankern und der Schiene belastet, wenn eine Kraft auf die Hammerkopfschraube wirkt, so dass die Haltekräfte abhängig von der Stabilität der Befestigung der Anker sind.the EP 3 081 707 A1 discloses an anchor channel for anchoring in concrete to fasten screws, in particular T-head screws. The anchor rail is designed as a U-shaped profile with webs on the two legs pointing inwards in order to fix the T-head bolts. Several anchors are fixed to the rail, which are intended to hold the rail in place after it has been cast in concrete. The manufacture of the anchor rail with the separately attached pin-shaped anchors is comparatively complex and requires a large number of separately manufactured components. In addition, the connection points between the anchors and the rail are loaded when a force acts on the T-head bolt, so that the holding forces are dependent on the stability of the attachment of the anchors.

In der DE 10 2008 029 838 A1 ist eine aus zwei Schienenteilen gebildete Ankerschiene offenbart, bei der die Schienenteile miteinander verschweißt sind.In the DE 10 2008 029 838 A1 discloses an anchor rail formed from two rail parts, in which the rail parts are welded to one another.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Ankerschiene zu schaffen, die einfach herstellbar ist und hohe Haltekräfte aufnehmen kann.It is therefore the object of the present invention to create an anchor rail that is easy to produce and can absorb high holding forces.

Diese Aufgabe wird mit einer Ankerschiene mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with an anchor rail having the features of claim 1.

Die erfindungsgemäße Ankerschiene umfasst ein erstes Schienenteil und ein zweites Schienenteil aus Metall, die eine Vielzahl von Ankerstegen aufweisen, wobei integral mit dem ersten und dem zweiten Schienenteil beabstandet von einem Schlitz zur Aufnahme von Befestigungsmitteln Verbindungsstege ausgebildet sind, die miteinander verschweißt sind. Dadurch kann die Ankerschiene aus nur zwei Schienenteilen hergestellt sein, die im Bereich der Verbindungsstege miteinander verschweißt sind, wobei die Kraftabtragung von dem Kanal für die Befestigungsmittel weitgehend unmittelbar über die Ankerstege erfolgt, so dass der Bereich der Verbindungsstelle zwischen den beiden Verbindungsstegen kaum belastet ist. Dadurch gewährleistet die Ankerschiene eine stabile und genaue Fixierung von Befestigungsmitteln und lässt sich einfach in unterschiedlichen Längen herstellen.The anchor rail according to the invention comprises a first rail part and a second rail part made of metal, which have a plurality of anchor webs, wherein connecting webs are formed integrally with the first and the second rail part at a distance from a slot for receiving fastening means and are welded to one another. As a result, the anchor rail can be made from just two rail parts, which are welded together in the area of the connecting webs, with the force being dissipated from the channel for the fastening means largely directly via the anchor webs, so that the area of the connection point between the two connecting webs is hardly loaded. As a result, the anchor rail ensures stable and precise fixing of fasteners and can be easily manufactured in different lengths.

Die Erfindung basiert auf der Erkenntnis, dass die Ankerschiene beim Vergießen häufig mit einem Rüttelgerät belastet ist, so dass der Beton noch im flüssigen Zustand auf die Ankerschiene drückt und diese verformen kann. Die Verbindung der Schienenteile ohne zwischengeschaltete Verbindungsstücke aus Kunststoff erhöht die Positionsgenauigkeit der Befestigungsmittel an der Ankerschiene, die unter 1mm liegt, vorzugsweise unter 0,5mm liegt. Durch das Herausbiegen der Verbindungsstege für die Verbindung an dem Boden des Kanals ist die Ankerschiene ausreichend stabilisiert.The invention is based on the finding that the anchor rail is often loaded with a vibrating device during casting, so that the concrete presses on the anchor rail while it is still in the liquid state and can deform it. The connection of the rail parts without intermediate connecting pieces made of plastic increases the positional accuracy of the fastening means on the anchor rail, which is less than 1 mm, preferably less than 0.5 mm. The anchor rail is sufficiently stabilized by bending out the connecting webs for the connection at the bottom of the channel.

Erfindungsgemäß sind die Verbindungsstege jeweils durch Ausstanzen und Biegen eines Abschnittes eines Ankersteges gebildet. Durch das Stanzen und Biegen eines Verbindungssteges wird eine Aussparung innerhalb eines Ankersteges gebildet, wobei wahlweise jeder Ankersteg, jeder zweite oder jeder dritte Ankersteg mit einem Verbindungssteg versehen sein kann. Es ist nicht zwingend erforderlich, dass an jedem Ankersteg ein Verbindungssteg vorgesehen ist.According to the invention, the connecting webs are each formed by punching out and bending a section of an anchor web. A recess is formed within an anchor bar by punching and bending a connecting bar, with each anchor bar, every second or every third anchor bar optionally being able to be provided with a connecting bar. It is not absolutely necessary for a connecting web to be provided on each anchor web.

Für die Verbindung der beiden Schienenteile können die Verbindungsstege auf Stoß miteinander verschweißt sein, was den Materialeinsatz reduziert. Der Stoß kann dabei linienförmig verlaufen, aber auch gestuft oder anderweitig profiliert sein, um die beiden Verbindungsstege an ihren Stirnkanten miteinander zu verbinden. Die Verbindungsstege können jeweils im Bereich einer Seitenwand des Kanals mit einem Ankersteg verbunden sein, so dass in Querschnittsansicht ein Boden des Kanals durch die Verbindungsstege gebildet wird, und die Ankerstege die Seitenwände und einen nach innen gerichteten Steg ausbilden, zwischen denen der Schlitz zur Aufnahme von Befestigungsmitteln ausgebildet ist. Optional können an den Verbindungsstegen zumindest teilweise Öffnungen ausgebildet sein, beispielsweise um die Verbindungsstege an einem Untergrund über Nägel oder andere Befestigungsmittel zu fixieren, bevor ein Vergießen von Beton erfolgt.To connect the two rail parts, the connecting webs can be butt-welded together, which reduces the amount of material used. The joint can run linearly, but also be stepped or profiled in some other way in order to connect the two connecting webs to one another at their front edges. The connecting webs can each be connected to an anchor web in the area of a side wall of the channel, so that in a cross-sectional view a bottom of the channel is formed by the connecting webs, and the anchor webs form the side walls and an inwardly directed web, between which the slot for receiving Fastening means is formed. Optionally, openings can be formed at least partially on the connecting webs, for example in order to fix the connecting webs to a substrate using nails or other fastening means before concrete is poured.

Die beiden Schienenteile können zu einer Mittelebene in Längsrichtung symmetrisch ausgebildet sein.The two rail parts can be symmetrical to a center plane in the longitudinal direction.

Das Füllungselement in dem Kanal umfasst vorzugsweise einen elastischen Schaumstoff, der in der Ankerschiene belassen wird, wenn die Befestigungsmittel, insbesondere Hammerkopfschrauben, in den Schlitz der Ankerschiene eingefügt werden. Dann wird der Schaumstoff im Bereich des Kopfes der Befestigungsmittel komprimiert und kann das Befestigungsmittel gegen die nach innen gerichteten Stege der Ankerschiene vorspannen. Dies kann die Montage vereinfachen, indem ein Herausdrehen des Kopfes der Befestigungsmittel durch den Schaumstoff verhindert wird. Das Füllungselement mit dem Schaumstoff verbleibt in der Ankerschiene und muss daher nicht entsorgt werden, was einen weiteren Montageschritt notwendig macht.The filling element in the channel preferably comprises a resilient foam which is left in the anchor channel when the fastening means, in particular hammer head screws, are inserted into the slot of the anchor rail. The foam is then compressed in the area of the head of the fastening means and can pretension the fastening means against the inwardly directed webs of the anchor rail. This can simplify assembly by preventing the head of the fastener from unscrewing through the foam. The filling element with the foam remains in the anchor rail and therefore does not have to be disposed of, which necessitates an additional assembly step.

Optional kann zwischen dem Füllungselement und den Verbindungsstegen eine Bodenleiste, insbesondere aus Kunststoff oder Metall, vorgesehen sein, die verhindert, dass Beton in den Schaumstoff eindringt. Die Bodenleiste kann beispielsweise aus einer streifenförmigen Folie bestehen.Optionally, a base strip, in particular made of plastic or metal, can be provided between the filling element and the connecting webs, which prevents concrete from penetrating the foam. The bottom bar can consist of a strip-shaped film, for example.

In einer weiteren Ausgestaltung sind integral mit den Ankerstegen seitlich nach außen hervorstehende Laschen ausgebildet. An den Laschen können eine oder mehrere Öffnungen für Befestigungsmittel vorgesehen sein, so dass die Ankerschiene auch im Bereich der Laschen vorfixiert werden kann.In a further embodiment, laterally outwardly protruding lugs are formed integrally with the anchor webs. One or more openings for fastening means can be provided on the lugs, so that the anchor rail can also be pre-fixed in the area of the lugs.

Um eine Verunreinigung der Ankerschiene im Bereich des Schlitzes zu vermeiden, kann der Schlitz durch eine Abnehmbare Abdeckung überdeckt sein, die mit der Ankerschiene und/oder dem Füllungselement verklebt ist. Die Abdeckung kann dann vor dem Einbringen der Befestigungsmittel abgezogen oder mit einer Öffnung versehen werden.In order to avoid contamination of the anchor rail in the area of the slot, the slot can be covered by a removable cover which is glued to the anchor rail and/or the filling element. The cover can then be peeled off or provided with an opening before inserting the fasteners.

In einer weiteren Ausgestaltung kann in zumindest einem Teil der Ankerstege eine Aussparung ausgebildet sein, in die eine Bewehrung eingefügt ist. Die Bewehrung kann beispielsweise aus U-förmiger Stab ausgebildet sein, der lose in die Ankerstege eingehängt wird. Dabei durchgreift die Bewehrung eine Aussparung an einem Ankersteg an dem ersten Schienenteil und eine weitere Aussparung an einem Ankersteg an dem zweiten Schienenteil. Alternativ kann die Bewegung auch zwei Aussparungen an zwei Ankerschienen an dem ersten Schienenteil oder dem zweiten Schienenteil durchgreifen, also nur an einem der beiden Schienenteile fixiert sein. In einer dritten Ausgestaltung kann die Bewehrung sowohl einen Ankersteg an dem ersten Schienenteil als auch einen Ankersteg an dem zweiten Schienenteil durchgreifen, so dass insgesamt vier Ankerstege durch die Bewehrung durchgriffen sind.In a further embodiment, a recess into which a reinforcement is inserted can be formed in at least part of the anchor webs. The reinforcement can be formed, for example, from a U-shaped bar that is hung loosely in the anchor webs. The reinforcement passes through a recess in an anchor web on the first rail part and a further recess in an anchor web on the second rail part. Alternatively, the movement can also pass through two recesses on two anchor rails on the first rail part or the second rail part, ie it can only be fixed on one of the two rail parts. In a third embodiment, the reinforcement can pass through both an anchor bar on the first rail part and an anchor bar on the second rail part, so that a total of four anchor bars pass through the reinforcement.

Die Bewehrung kann U-förmig ausgebildet sein, wobei vorzugsweise im Bereich des Bügelabschnittes eine Abkröpfung vorgesehen ist, so dass der Bügelabschnitt nicht mehr der durch die Schenkel aufgespannten Ebene angeordnet ist. Dies erleichtert die Montage und Ausrichtung der Bewehrung. Die Bewehrung kann dabei in der eingebauten Position sowohl parallel zur Ebene der Verbindungsstege mit den Stäben verlaufen als auch senkrecht hierzu, je nachdem, in welche Richtung die Belastungen auf die Ankerschiene ausgeübt werden.The reinforcement can be U-shaped, with a bend preferably being provided in the area of the stirrup section, so that the stirrup section is no longer arranged in the plane spanned by the legs. This facilitates the assembly and alignment of the reinforcement. In the installed position, the reinforcement can run both parallel to the plane of the connecting webs with the bars and perpendicular thereto, depending on the direction in which the loads are exerted on the anchor rail.

Zur Befestigung an den nach innen gerichteten Stegen können jeweils Verzahnungen ausgebildet sein, die formschlüssig zur Fixierung eines Kopfes einer Hammerkopfschraube oder eines anderen Befestigungsmittels dienen.For attachment to the inwardly directed webs, teeth can be formed in each case, which serve to fix a head of a hammer-head screw or another attachment means in a form-fitting manner.

Bei der erfindungsgemäßen Ankerschiene ist vorzugsweise zwischen den Ankerstegen ein Schlitz im Bereich der Seitenwände an dem Kanal ausgebildet, der ein Abtrennen der Ankerschiene in der gewünschten Länge erleichtert. Zudem kann der Schlitz zwischen den Ankerstegen im Bereich der Seitenwände für eine Elastizität in Längsrichtung sorgen, so dass die Ankerschiene auch in einem gebogenen Zustand verarbeitet werden kann.In the case of the anchor rail according to the invention, a slot is preferably formed between the anchor webs in the area of the side walls on the channel, which slit makes it easier to cut off the anchor rail to the desired length. In addition, the slot between the anchor webs in the area of the side walls can ensure elasticity in the longitudinal direction, so that the anchor rail can also be processed in a bent state.

Die beiden Schienenteile 1a und 1b weisen jeweils eine Vielzahl von Ankerstegen 2 auf, die sich senkrecht zur Längsrichtung erstrecken und in der montierten Position in Beton eingebettet sind.An anchor rail 1 comprises a first rail part 1a and a second rail part 1b, both of which are made of metal, in particular by bending and stamping a steel sheet. The two rail parts 1a and 1b each have a multiplicity of anchor webs 2, which extend perpendicular to the longitudinal direction and are embedded in concrete in the mounted position.

Jeder Ankersteg 2 umfasst einen verbreiterten Fußabschnitt 20, der über einen aufspreizenden Abschnitt 21 mit einer Seitenwand 23 verbunden ist, die einen rohrförmigen Kanal umgibt, in dem ein Füllungselement 5 angeordnet ist. Integral mit der Seitenwand 23 sind nach innen gerichtete Stege 24 ausgebildet, an denen eine Verzahnung 7 vorgesehen ist. Zwischen den beiden Verzahnungen 7 an den beiden Stegen 24 ist ein Schlitz 6 zur Aufnahme von Befestigungsmitteln vorgesehen.Each anchor web 2 comprises a widened foot section 20 which is connected via a spreading section 21 to a side wall 23 which surrounds a tubular channel in which a filling element 5 is arranged. Inwardly directed webs 24 are formed integrally with the side wall 23, on which a toothing 7 is provided. Between the two toothings 7 on the two webs 24 there is a slot 6 for receiving fastening means.

Die beiden Schienenteile 1a und 1b sind über eine Vielzahl von Verbindungsstegen 3 miteinander verbunden, die integral mit den Ankerstegen 2 ausgebildet sind. Dabei ist an jedem Ankersteg eine Aussparung 22 ausgebildet, die durch Stanzen und Biegen eines Verbindungssteges 3 hergestellt ist, der winklig zu dem Ankersteg 2 ausgerichtet ist. Zwei Verbindungsstege 3 sind dabei in einem Stoßbereich 4, also an einer Stirnkante der Verbindungsstege 3, miteinander verschweißt. Der Stoßbereich 4 ist in dem dargestellten Ausführungsbeispiel als gerade Kante ausgebildet, kann aber auch stufenförmig oder anderweitig profiliert sein.The two rail parts 1a and 1b are connected to one another via a large number of connecting webs 3 which are formed integrally with the anchor webs 2 . A recess 22 is formed on each anchor bar, which is produced by punching and bending a connecting bar 3 which is aligned at an angle to the anchor bar 2 . Two connecting webs 3 are welded together in a joint area 4, ie at a front edge of the connecting webs 3. The abutting area 4 is designed as a straight edge in the exemplary embodiment shown, but it can also be stepped or profiled in some other way.

Wie in Figur 1C gezeigt ist, spreizen die Ankerstege 2 des Schienenteils 1a und des Schienenteils 1b nach außen auf und besitzen im Bereich der Fußabschnittes 20 eine größere Breite als die Breite des Kanals. Die Ankerstege sind in einem Winkel α zur Seitenwand 23 ausgerichtet, der beispielsweise zwischen 10° und 30° liegt.As in Figure 1C is shown, the anchor webs 2 of the rail part 1a and the rail part 1b spread outwards and have a greater width in the area of the foot section 20 than the width of the channel. The anchor webs are aligned at an angle α to the side wall 23, which is between 10° and 30°, for example.

In dem Kanal, der an der Unterseite durch die Verbindungsstege 3, an dem beiden Seiten durch die Seitenwände 23 und an der Oberseite zumindest am Rand durch die nach innen gerichteten Stege 24 begrenzt wird, ist ein Füllungselement 5 eingefügt, das aus einem elastischen Material, insbesondere einem elastischen Schaumstoff, hergestellt ist. Dadurch wird ein Eindringen von Beton in den Kanal vermieden. Der elastische Schaumstoff kann nach dem Vergießen von Beton in dem Kanal verbleiben. Um eine Verunreinigung des Schlitzes 6 und des Füllungselementes 5 zu vermeiden, ist vorzugswiese eine Abdeckung 8 vorgesehen, beispielsweise eine Klebefolie, die mit dem Füllungselement 5 und/oder den nach innen gerichteten Stegen 24 verklebt ist. vor der Montage von Befestigungsmitteln kann die Abdeckung 8 entfernt oder aufgeschnitten werden.In the channel, which is delimited on the underside by the connecting webs 3, on both sides by the side walls 23 and on the top at least at the edge by the inwardly directed webs 24, a filling element 5 is inserted, which consists of an elastic material, in particular an elastic foam. This prevents concrete from entering the channel. The elastic foam can after Pouring concrete left in the channel. In order to avoid contamination of the slot 6 and the filling element 5, a cover 8 is preferably provided, for example an adhesive film which is glued to the filling element 5 and/or the inwardly directed webs 24. before mounting fasteners, the cover 8 can be removed or cut open.

In den Figuren 1A bis 1D ist in jedem Ankersteg 2 ein Verbindungssteg 3 integral ausgebildet. Es ist natürlich möglich, die Anzahl der Verbindungsstege 3 zu reduzieren und nur in jedem zweiten Ankersteg oder jedem dritten Ankersteg 2 einen Verbindungssteg 3 auszuformen.In the Figures 1A to 1D a connecting web 3 is integrally formed in each anchor web 2 . It is of course possible to reduce the number of connecting webs 3 and to form a connecting web 3 only in every second anchor web or every third anchor web 2 .

In den Verbindungsstegen 3 sind ferner Öffnungen 15 vorgesehen, die zur Fixierung der Ankerschiene 1 an einem Untergrund dienen können, beispielsweise durch Anbringen von Nägeln vor dem Gießen von Beton.Also provided in the connecting webs 3 are openings 15 which can be used to fix the anchor rail 1 to a substrate, for example by attaching nails before the concrete is poured.

Zwischen benachbarten Ankerstegen 2 sind ferner im Bereich der Seitenwand 23 Schlitze 28 ausgebildet, so dass benachbarte Ankerstege 2 nur über eine Materialverjüngung miteinander verbunden sind. Durch die Schlitze 28 kann die Ankerschiene 1 gebogen werden, um auch in gebogener Form verarbeitet zu werden. Zudem erleichtern die Schlitze 28 das Abtrennen der Ankerschiene 1 in der gewünschten Länge.Slots 28 are also formed between adjacent anchor bars 2 in the area of the side wall 23, so that adjacent anchor bars 2 are only connected to one another via a material taper. The anchor rail 1 can be bent through the slots 28 so that it can also be processed in a bent shape. In addition, the slots 28 make it easier to cut off the anchor rail 1 to the desired length.

In den Figuren 2A und 2B ist die Ankerschiene 1 der Figuren 1A bis 1D gezeigt, wobei zusätzlich eine Bewehrung 10 in Form eines U-förmigen Stabes montiert ist. Die Bewehrung 10 besitzt einen Bügelabschnitt 11 und zwei nach unten ragende Schenkel 12. Der Bügelabschnitt 11 durchgreift dabei Aussparungen 22 an zwei Ankerstegen 2, wobei ein Ankersteg 2 an dem ersten Schienenteil 1a und ein Ankersteg 2 an dem zweiten Schienenteil 1b durchgriffen wird.In the Figures 2A and 2B is the anchor rail 1 of Figures 1A to 1D shown, with an additional reinforcement 10 is mounted in the form of a U-shaped rod. The reinforcement 10 has a bracket section 11 and two downwardly projecting legs 12. The bracket section 11 reaches through recesses 22 on two anchor webs 2, with an anchor web 2 on the first rail part 1a and an anchor web 2 on the second rail part 1b being reached through.

In den Figuren 3A bis 3D ist eine modifizierte Ankerschiene 1' gezeigt, die ebenfalls zwei Schienenteile 1a' und 1b' aus einem Metallblech aufweist, die über Verbindungsstege 3 miteinander verbunden sind. Ferner umfasst jedes Schienenteil 1a' und 1b' Ankerstege 2 ähnlich dem vorangegangenen Ausführungsbeispiel. Alleedings sind nicht in jedem Ankersteg 2 integral Verbindungsstege 3 ausgebildet, sondern nur in jedem zweiten Ankersteg 2. Die Verbindungsstege 3 sind an dem Stoßbereich 4 miteinander verschweißt wie bei dem vorangegangenen Ausführungsbeispiel.In the Figures 3A to 3D 1 shows a modified anchor rail 1 ′, which also has two rail parts 1 a ′ and 1 b ′ made of sheet metal, which are connected to one another via connecting webs 3 . Furthermore, each rail part 1a' and 1b' comprises anchor webs 2 similar to the previous exemplary embodiment. However, connecting webs 3 are not formed integrally in every anchor web 2, but only in every second anchor web 2. The connecting webs 3 are welded to one another at the joint area 4, as in the previous exemplary embodiment.

Die Ankerstege 2 ohne Verbindungssteg 3 sind mit ausgestanzten Laschen 25 versehen, die statt nach innen zu der Unterseite des Kanals nach außen umgebogen sind. Wie dies aus der Figur 3C ersichtlich ist. In die von dem Kanal nach außen hervorstehenden Laschen 25 können an einer Öffnung 26 Nägel oder andere Befestigungsmittel zur Fixierung der Ankerschiene 1' an einem Untergrund eingebracht werden.The anchor bars 2 without a connecting bar 3 are provided with punched tabs 25 which are bent outwards instead of inwards towards the underside of the channel. Like this from the Figure 3C is evident. At an opening 26, nails or other fastening means for fixing the anchor rail 1' to a substrate can be introduced into the tabs 25 protruding outwards from the channel.

Ferner ist bei der Ankerschiene 1' im Kanal auf den Verbindungsstegen 3 eine Bodenleiste 30 unter dem Füllungselement 5 angeordnet. Die Bodenleiste 30 kann aus einer Folie aus Kunststoff oder Metall gebildet sein, die streifenförmig in Längsrichtung des Kanals angeordnet ist und ein Eindringen von Beton in den Kanal verhindert. Dadurch wird gewährleistet, dass das Füllungselement 5, insbesondere der Schaumstoff, seine Elastizität beim Vergießen von Beton beibehält. Im Übrigen entspricht die Ankerschiene 1' dem vorangegangenen Ausführungsbeispiel, und gleiche Bauteile sind mit den gleichen Bezugszeichen versehen.Furthermore, a base strip 30 is arranged under the filling element 5 in the anchor rail 1 ′ in the channel on the connecting webs 3 . The bottom strip 30 can be formed from a foil made of plastic or metal, which is arranged in strips in the longitudinal direction of the channel and prevents concrete from penetrating into the channel. This ensures that the filling element 5, in particular the foam, retains its elasticity when pouring concrete. Otherwise, the anchor rail 1′ corresponds to the previous exemplary embodiment, and the same components are provided with the same reference numbers.

In den Figuren 4A und 4B ist die Ankerschiene 1' zusammen mit einem Befestigungsmittel 40 im montierten Zustand gezeigt. Das Befestigungsmittel 40 ist als Hammerkopfschraube ausgebildet und umfasst einen Kopfabschnitt 42, der in den Kanal der Ankerschiene 1' eingreift und das Füllungselement 5 komprimiert. Der Kopfabschnitt 42 ist dabei länglich ausgebildet und wird in den Schlitz 6 eingesteckt und dann um etwa 90° gedreht, so dass äußere Bereiche des Kopfabschnittes 42 die nach innen ragenden Stege 24 hintergreifen. Dabei gelangt eine Verzahnung 41 an dem Kopfabschnitt 42 in Eingriff mit der Verzahnung 7 an dem Schlitz 6. Von dem Kopfabschnitt 42 erstreckt sich ein Gewindeabschnitt 43 heraus, an dem Befestigungsmittel, wie eine Mutter, festgelegt werden können. Zur Montage der Hammerkopfschraube muss lediglich die Abdeckung 8 entfernt oder eine Öffnung in der Abdeckung 8 hergestellt werden.In the Figures 4A and 4B the anchor rail 1 'is shown together with a fastener 40 in the assembled state. The fastening means 40 is designed as a hammer head screw and comprises a head section 42 which engages in the channel of the anchor rail 1' and compresses the filling element 5. The head section 42 is elongate and is inserted into the slot 6 and then rotated by approximately 90°, so that the outer areas of the head section 42 engage behind the inwardly projecting webs 24 . A toothing 41 on the head section 42 comes into engagement with the toothing 7 on the slot 6. A threaded section 43 extends out from the head section 42, on which fastening means, such as a nut, can be fixed. To mount the hammer head screw, only the cover 8 has to be removed or an opening made in the cover 8.

Die Ankerschiene 1, 1' kann abgesehen von dem Füllungselement 5 und einer etwaigen Bodenleiste 30 aus nur zwei metallischen Schienenteilen 1a und 1b hergestellt werden, die über die Verbindungsstege 3 aneinander festgelegt sind. Dabei kann die Form der Ankerstege 2 variiert werden. Diese können auch in anderer Form von dem Kanal hervorstehen.Apart from the filling element 5 and any base strip 30, the anchor rail 1, 1' can be produced from only two metal rail parts 1a and 1b, which are fixed to one another via the connecting webs 3. The shape of the anchor bars 2 can be varied. These can also protrude from the channel in other forms.

In den Figuren 5A bis 5D ist die Ankerschiene 1 der Figuren 1 und 2 in einer teilweise eingebauten Position gezeigt, in der ein Betonblock 60 dargestellt ist. Eine Oberseite der Ankerschiene schließt dabei im Wesentlichen flächenbündig mit einer Oberseite des Betonblocks 60 ab. Die Ankerstege 2 sind in das Betonmaterial eingegossen, wobei zumindest in einige der Ankerstege 2 Bewehrungen 10' eingefügt sind. Die Bewehrungen 10' sind U-förmig ausgebildet und weisen einen Bügelabschnitt 11 und zwei stabförmige Schenkel 12 auf. Im Bereich des Bügelabschnittes 11 weist die Bewehrung 10' eine Abkröpfung 13 auf, so dass der Bügelabschnitt 11 nicht mehr in der durch die Schenkel 12 aufgespannten Ebene angeordnet ist, sondern geneigt hierzu verläuft, beispielsweise in einem Winkel zwischen 15° und 50°. Die Bewehrung 10' kann aus Draht hergestellt sein, insbesondere einem Betonrippenstahl, und für eine direkte Krafteinleitung an dem Übergang zwischen Ankerschiene und Bewehrung sorgen. Durch die Abkröpfung 13 kann die Bewehrung 10' mit unterschiedlicher Ausrichtung an der Ankerschiene 1 befestigt werden.In the Figures 5A to 5D is the anchor rail 1 of figures 1 and 2 shown in a partially installed position in which a concrete block 60 is shown. An upper side of the anchor rail terminates essentially flush with an upper side of the concrete block 60 . The anchor bars 2 are cast into the concrete material, with at least some of the anchor bars 2 having reinforcements 10' inserted therein. The reinforcements 10' are U-shaped and have a bracket section 11 and two rod-shaped legs 12. In the area of the stirrup section 11, the reinforcement 10' has a bend 13, so that the stirrup section 11 is no longer arranged in the plane spanned by the legs 12, but runs inclined thereto, for example at an angle between 15° and 50°. The reinforcement 10' can be made of wire, in particular a rebar, and ensure a direct introduction of force at the transition between the anchor rail and the reinforcement. Due to the offset 13, the reinforcement 10' can be attached to the anchor rail 1 with different orientations.

In den Figuren 5A bis 5B ist die Bewehrung 10' mit den Schenkeln 12 nach unten ausgerichtet, also senkrecht zu einer durch die Verbindungsstege 3 aufgespannten Ebene.In the Figures 5A to 5B the reinforcement 10 ′ is aligned with the legs 12 downwards, that is to say perpendicular to a plane spanned by the connecting webs 3 .

In den Figuren 6A bis 6C ist die Ankerschiene 1 ebenfalls in einer Einbausituation an einem Betonblock 50 dargestellt, allerdings ist die Bewehrung 10' mit den Schenkeln 12 um 90° versetzt angeordnet, so dass die Schenkel 12 im Wesentlichen parallel zu den Verbindungsstegen 3 an der Ankerschiene angeordnet sind. Die Bewehrung 10' ist durch die Aussparungen 22 an einer der beiden Scheinenteile 1a oder 1b eingesteckt. Dabei durchgreifen die Schenkel 12 zwei Aussparungen 22 an zwei benachbarten Ankerstegen 2.In the Figures 6A to 6C the anchor rail 1 is also shown in an installation situation on a concrete block 50, but the reinforcement 10' with the legs 12 is arranged offset by 90°, so that the legs 12 are arranged essentially parallel to the connecting webs 3 on the anchor rail. The reinforcement 10' is inserted through the recesses 22 on one of the two bar parts 1a or 1b. The legs 12 pass through two recesses 22 on two adjacent anchor bars 2.

Zudem ist es möglich, die Bewehrung 10' durch einen ersten Ankersteg 2 an dem Schienenteil 1a und einen zweiten Ankersteg 2 an dem zweiten Schienenteil 1b einzufügen, wie dies in Figur 6C beispielshaft dargestellt ist. Die Schenkel 12 können dann sowohl parallel zur Ebene der Verbindungsstege 3 als auch geneigt hierzu ausgerichtet sein.It is also possible to insert the reinforcement 10' through a first anchor bar 2 on the rail part 1a and a second anchor bar 2 on the second rail part 1b, as shown in Figure 6C is shown as an example. The legs 12 can then be aligned both parallel to the plane of the connecting webs 3 and inclined thereto.
