Description

Verankerungselement und Verfahren zur Montage einer Ankerschiene in einem Baukörper aus Beton Anchoring element and method for assembling an anchor rail in a concrete structure
Die vorliegende Erfindung betrifft ein Verankerungselement zum Vergießen in Beton, mit einer Ankerschiene mit einer Vielzahl von Ankerstegen und einer leistenförmigen Aufnahme zur Montage von Befestigungsmitteln, wobei an der Ankerschiene mindestens ein Haltebügel fixiert ist, der die Ankerschiene senk recht zu ihrer Längsrichtung übergreift und über den die Ankerschiene an ei nem Schalungsbauteil festlegbar ist, wobei an dem Haltebügel mindestens ein seitlich von der Ankerschiene hervorstehender Flansch ausgebildet ist und ein Verfahren zur Montage einer Ankerschiene in einem Baukörper aus Beton. The present invention relates to an anchoring element for casting in concrete, with an anchor rail with a plurality of anchor webs and a strip-shaped receptacle for mounting fasteners, with at least one retaining bracket being fixed to the anchor rail, which engages over the anchor rail perpendicular to its longitudinal direction and over the the anchor rail can be fixed to a formwork component, with at least one flange protruding laterally from the anchor rail being formed on the retaining bracket, and a method for assembling an anchor rail in a concrete structure.
Die DE 102008029838 A1 offenbart eine Ankerschiene zur Fixierung von Be festigungsmitteln an einem Baukörper aus Beton, wobei die Ankerschiene eine Vielzahl von Ankerstegen aufweist, die in den Beton eingegossen werden. Um eine solche Ankerschiene vor dem Vergießen von Beton zu positionieren, ist es bekannt, die Ankerschiene über Nägel an einem Schalungsbauteil zu fixieren. Nach dem Vergießen von Beton wird das Schalungsbauteil dann entfernt, wo bei die Nägel im Beton verbleiben. Dies führt zu dem Nachteil, dass die Nägel ein Verletzungsrisiko darstellen und sich Roststellen an den Nägeln bilden. Zu dem besteht der Nachteil, dass die Nägel im Montagebereich der Ankerschiene störend sind. Das Einbringen von Nägeln in kleine Öffnungen an der Anker schiene ist zudem im Hinblick auf die Montage aufwändig, da die Nägel nicht mit sogenannten Nagelpistolen eingeschossen werden können. DE 102008029838 A1 discloses an anchor rail for fixing loading fastening means on a structure made of concrete, the anchor rail having a plurality of anchor bars which are cast into the concrete. In order to position such an anchor rail before concrete is poured, it is known to fix the anchor rail to a formwork component by means of nails. After the concrete has been poured, the formwork component is then removed, where the nails remain in the concrete. This leads to the disadvantage that the nails pose a risk of injury and rust spots form on the nails. In addition, there is the disadvantage that the nails in the assembly area of the anchor rail are disruptive. The introduction of nails into small openings on the anchor rail is also complex in terms of assembly, since the nails cannot be shot with so-called nail guns.
Die US 2005/0217197 A1 offenbart eine Klammer zur Fixierung einer Schiene in einem Betonbauteil, bei der an einem Bügel zwei hülsenförmige Befesti gungselemente angeformt sind, die dann beim Abnehmen einer Schalung ab gerissen werden. In der Schalung sind Öffnungen ausgebildet, in die die hül senförmigen Befestigungselemente einfügbar sind. Die Montage dieser Klam mern mit den Befestigungselementen ist daher aufwändig. US 2005/0217197 A1 discloses a clamp for fixing a rail in a concrete component, in which two sleeve-shaped fastening elements are formed on a bracket, which are then torn off when a formwork is removed. Openings are formed in the formwork, into which the sleeve-shaped fastening elements can be inserted. The assembly of these Klam numbers with the fasteners is therefore complex.
In der GB 2243395 A ist eine Schiene über Klammern an einer Schalung fi xiert, um die Schiene in eine Betonbauteil zu vergießen. Die Klammer wird über Nägel an der Schalung befestigt, die beim Entfernen der Schalung aus der Klammer herausgezogen werden sollen. Falls die Nägel in der Klammer ver- bleiben, stehen die Spitzen der Nägel von dem Betonteil hervor und stellen ein Verletzungsrisiko dar. In GB 2243395 A, a rail is fixed to formwork using brackets in order to cast the rail in a concrete component. The bracket is attached to the formwork with nails that are intended to be pulled out of the bracket when the formwork is removed. If the nails get caught in the clamp remain, the tips of the nails protrude from the concrete part and pose a risk of injury.
Es ist daher Aufgabe der vorliegenden Erfindung, ein Verankerungselement mit einer Ankerschiene sowie ein Verfahren zur Montage einer Ankerschiene in ei nem Baukörper aus Beton zu schaffen, die eine einfache Montage und eine si chere Positionierung der Ankerschiene gewährleisten. It is therefore the object of the present invention to provide an anchoring element with an anchor rail and a method for mounting an anchor rail in egg nem structure made of concrete, which ensure simple assembly and secure positioning of the anchor rail.
Diese Aufgabe wird mit einem Verankerungselement mit den Merkmalen des Anspruches 1 sowie einem Verfahren zur Montage einer Ankerschiene mit den Merkmalen des Anspruches 12 gelöst. This object is achieved with an anchoring element having the features of claim 1 and a method for assembling an anchor rail having the features of claim 12.
Bei dem erfindungsgemäßen Verankerungselement ist eine Ankerschiene mit einer Vielzahl von Ankerstegen und einer leistenförmigen Aufnahme zur Mon tage von Befestigungsmitteln, wie Hammerkopfschrauben, vorgesehen, wobei die Ankerschiene über mindestens einen Haltebügel fixiert ist, über den die An kerschiene an einem Schalungsbauteil festlegbar ist. Der Haltebügel ermöglicht eine sichere Positionierung und Ausrichtung der Ankerschiene an dem Scha lungsbauteil und eine indirekte formschlüssige Befestigung der Ankerschiene, da die Ankerschiene über den mindestens einen Haltebügel an dem Scha lungsbauteil festlegbar ist. Die Fixierung der Haltbügel erleichtert die Montage der Ankerschiene vor dem Vergießen von Beton. In the anchoring element according to the invention, an anchor rail with a plurality of anchor webs and a strip-shaped receptacle for Mon days of fasteners, such as hammer head screws, is provided, the anchor rail being fixed via at least one bracket, via which the anchor rail can be fixed to a formwork component. The retaining bracket enables secure positioning and alignment of the anchor rail on the formwork component and an indirect form-fitting fastening of the anchor rail, since the anchor rail can be fixed to the formwork component via the at least one retaining bracket. The fixation of the retaining brackets makes it easier to assemble the anchor rail before pouring concrete.
Dabei übergreift der mindestens eine Haltebügel die Ankerschiene senkrecht zu ihrer Längsrichtung. An dem Haltebügel ist mindestens ein seitlich von der Ankerschiene hervorstehender Flansch ausgebildet, bevorzugt ist an gegen überliegenden Seiten jeweils ein Flansch vorgesehen. Jeder Flansch ist dabei über eine Sollbruchstelle mit einem mittleren Abschnitt des Haltebügels ver bunden. Dies ermöglicht eine Fixierung der Ankerschiene über Fixierelemente, wie Nägel oder Heftklammern, die in den Flansch eingebracht werden. Beim Entfernen des Schalungsbauteils kann dann der Flansch zusammen mit dem Fixierelement von der Ankerschiene entfernt werden, so dass an dem Baukör per aus Beton keine Fixierelemente verbleiben. Beim Entfernen des Scha lungsbauteils werden kann die Flansche von dem mittleren Abschnitt des Hal tebügels abgetrennt. Die durch das Entfernen des Flansches entstehende Ver tiefung in dem Betonkörper ist im Hinblick auf die Haltekräfte der Ankerschiene und die optische Beeinträchtigung vernachlässigbar. Der Flansch kann bei spielsweise eine Dicke von weniger als 5 mm besitzen, vorzugsweise zwischen 1 mm bis 4 mm, so dass dieser leicht durchdrungen werden kann und die im Beton verbleibende Vertiefung durch das Entfernen des Flansches gering ist. Die Größe jedes Flansches kann beispielsweise zwischen 1 cm2 bis 4 cm2 be tragen und ist somit bei der Montage leicht zu treffen. The at least one retaining bracket engages over the anchor rail perpendicular to its longitudinal direction. At least one flange protruding laterally from the anchor rail is formed on the retaining bracket; a flange is preferably provided on each opposite side. Each flange is connected via a predetermined breaking point with a central section of the retaining bracket a related party. This enables the anchor rail to be fixed using fixing elements, such as nails or staples, which are introduced into the flange. When removing the formwork component, the flange can then be removed from the anchor rail together with the fixing element, so that no fixing elements remain on the building body made of concrete. When removing the formwork component, the flanges can be separated from the central portion of the bracket. The resulting recess in the concrete body by removing the flange is negligible with regard to the holding forces of the anchor rail and the visual impairment. The flange can for example have a thickness of less than 5 mm, preferably between 1 mm to 4 mm, so that it can be easily penetrated and the im Concrete recess remaining by removing the flange is small. The size of each flange can be, for example, between 1 cm 2 to 4 cm 2 and is therefore easy to meet during assembly.
Für eine einfache Montage der Flaltebügel können diese auf die Ankerschiene aufgesteckt werden. Die Flaltebügel können dabei klemmend oder rastend an der Ankerschiene fixiert werden. An einer Innenseite des Haltbügels kann eine Positionierhilfe, beispielsweise ein Steg oder ein Vorsprung, vorgesehen sein, der in eine Aufnahme oder Aussparung an der Ankerschiene eingreift, um ein Verschieben der Ankerschiene in Längsrichtung zu verhindern. For easy assembly of the folding brackets, they can be attached to the anchor rail. The folding brackets can be fixed to the anchor rail by clamping or locking. A positioning aid, for example a web or a projection, which engages in a receptacle or recess on the anchor rail in order to prevent displacement of the anchor rail in the longitudinal direction, can be provided on an inside of the retaining bracket.
Jede Ankerschiene wird vorzugsweise über mehrere Haltebügel an einem Schalungsbauteil fixiert. Der Haltebügel ist vorzugsweise aus Kunststoff herge stellt, kann aber auch aus anderen Materialien gefertigt werden. Each anchor rail is preferably fixed to a formwork component by means of several retaining brackets. The retaining bracket is preferably made of plastic Herge, but can also be made of other materials.
Das Verankerungselement wird vorzugsweise vor dem Vergießen zu einer Ein heit montiert, bei der die Ankerschiene über mindestens einen Haltebügel an einem plattenförmigen Schalungsbauteil fixiert ist. Dabei ist der mindestens ei ne Haltebügel über mindestens ein Fixierelement, vorzugsweise über jeweils einen Nagel an einem hervorstehenden Flansch des Schalungsbauteils, fixiert. The anchoring element is preferably assembled into a unit before casting, in which the anchor rail is fixed to a plate-shaped formwork component via at least one retaining bracket. In this case, the at least one retaining bracket is fixed to a protruding flange of the formwork component via at least one fixing element, preferably via a nail in each case.
Eine solche Einheit kann auch in beliebiger Länge hergestellt werden, wobei zur Ausrichtung zweier benachbarter Ankerschienen ein Haltebügel eingesetzt wird, der im Stoßbereich beide Ankerschienen übergreift. Dadurch können die beiden Ankerschienen über den Haltebügel fluchtend ausgerichtet werden. Such a unit can also be produced in any length, with a retaining bracket being used to align two adjacent anchor rails, which extends over both anchor rails in the joint area. This allows the two anchor rails to be aligned using the retaining bracket.
Bei dem erfindungsgemäßen Verfahren zur Montage einer Ankerschiene in ei nem Baukörper aus Beton wird zunächst eine Ankerschiene an einem Scha lungsbauteil positioniert, um dann mindestens einen Haltebügel über der An kerschiene anzuordnen. Anschließend wird der Haltebügel über mindestens ein Fixierelement, insbesondere einen Nagel, an dem Schalungsbauteil fixiert, um dann die Ankerschiene in Beton zu vergießen. Anschließend wird das Scha lungsbauteil mit dem mindestens einen Fixierelement von der Ankerschiene entfernt. Dadurch kann das Fixierelement an dem Baukörper aus Beton kein Sicherheitsrisiko mehr darstellen oder zu einer optischen Beeinträchtigung durch Rost führen. Vorzugsweise wird beim Entfernen mindestens ein Flansch des Haltebügels mit dem Fixierelement entfernt, wobei der Flansch entlang ei ner Sollbruchstelle von einem mittleren Abschnitt des Haltebügels abgetrennt wird. Dadurch stört kein Fixierelement im Montagebereich des Kanals der An- kerschiene. Für eine effektive Montage sind die Fixierelemente als Nägel aus gebildet sind und werden über eine Nagelpistole in das Schalungsbauteil ein geschossen werden. In the method according to the invention for mounting an anchor rail in egg nem structure made of concrete, an anchor rail is first positioned on a formwork component in order to then arrange at least one bracket over the anchor rail. The retaining bracket is then fixed to the formwork component via at least one fixing element, in particular a nail, in order then to cast the anchor rail in concrete. The formwork component with the at least one fixing element is then removed from the anchor rail. As a result, the fixing element on the concrete structure can no longer pose a safety risk or lead to a visual impairment due to rust. Preferably, at least one flange of the retaining bracket with the fixing element is removed during removal, the flange being separated from a central section of the retaining bracket along a predetermined breaking point. As a result, no fixing element in the assembly area of the channel interferes with the kerschiene. For effective assembly, the fixing elements are designed as nails and are shot into the formwork component using a nail gun.

Jeder Haltebügel 20 weist dabei einen mitt leren bügelförmigen Abschnitt 21 auf, an dem an gegenüberliegenden Seiten jeweils ein Flansch 22 angeformt ist. Der Flansch 22 kann über ein Fixierele ment 11 , wie einen Nagel oder eine Heftklammer, mit dem Schalungsbauteil 10 verbunden werden, um die Ankerschiene 1 mittelbar über die Haltebügel 20 an dem Schalungsbauteil 10 festzulegen. The anchor rail 1 comprises a plurality of anchor webs 2 which protrude from a strip-shaped rail part with a receptacle for mounting fasteners supply means. Each anchor bar 2 has a widened end section and is poured into concrete. A shaped body 4 made of an elastic material is inserted into the receptacle of the rail part, which prevents concrete from penetrating into the receptacle. The anchor rail 1 can be made from two rail parts which are fixed to one another via connecting webs 5. On the side facing the formwork component 10, a channel-shaped receptacle for fastening means, such as hammer head screws, can be formed. The anchor rail 1 can be designed as is disclosed in document DE 102019 106 155. The at least one retaining bracket 20 engages over the anchor rail 1 in a direction perpendicular to the longitudinal direction. Each retaining bracket 20 has a middle bracket-shaped section 21 on which a flange 22 is formed on opposite sides. The flange 22 can be connected to the formwork component 10 via a fixing element 11, such as a nail or a staple, in order to fix the anchor rail 1 indirectly via the retaining bracket 20 on the formwork component 10.
In den Figuren 2A bis 2D ist die Ankerschiene in einer an einem Schalungsbau teil 10 montierten Position gezeigt. Dabei sind zwei Haltebügel 20 an dem Schalungsbauteil 10 montiert. Der in Figur 2A auf der linken Seite gezeigte Hal tebügel 20 ist über Fixierelemente 11 in Form von Nägeln an dem Schalungs bauteil 10 festgelegt, wobei die Nägel jeweils in den Flansch 22 an dem Halte bügel 20 eingebracht sind. Der Haltebügel 20 auf der rechten Seite in Figur 2A ist ebenfalls über einen Nagel als Fixierelement 11 an dem Schalungsbauteil 10 festgelegt, wobei das Fixierelement 11 einen bügelförmigen mittleren Ab schnitt 21 des Haltebügels 20 durchgreift, so dass nur ein Nagel verwendet wird statt der zwei Nägel für den Haltebügel 20 auf der linken Seite. In FIGS. 2A to 2D, the anchor rail is shown in a position mounted on a formwork component 10. Two retaining brackets 20 are mounted on the formwork component 10. The Hal tebügel 20 shown in Figure 2A on the left side is fixed by fixing elements 11 in the form of nails on the formwork component 10, the nails are each introduced into the flange 22 on the holding bracket 20. The retaining bracket 20 on the right-hand side in Figure 2A is also fixed by a nail as a fixing element 11 on the formwork component 10, the fixing element 11 passing through a bracket-shaped central section 21 of the retaining bracket 20, so that only one nail is used instead of the two nails for the retaining bracket 20 on the left side.
In den Figuren 3A bis 3C ist die Situation nach dem Vergießen von Beton ge zeigt, wenn die Ankerschiene 1 mit den Ankerstegen 2 in einem Baukörper aus Beton eingegossen ist, der zur vereinfachten Darstellung nicht gezeigt ist. Dann kann das Schalungsbauteil 10 von der Ankerschiene 1 entfernt werden, wobei bei dem Haltebügel 20 auf der linken Seite beim Entfernen des Schalungsbau teils 10 die Fixierelemente 11 an dem Schalungsbauteil 10 verbleiben und ein Flansch 22 über eine Sollbruchstelle 24 von einem mittleren Abschnitt 21 des Haltebügels 20 abgetrennt wird. Dadurch können die Fixierelemente in Form von Nägeln von dem Baukörper aus Beton entfernt werden. In Figures 3A to 3C, the situation after the pouring of concrete is shown when the anchor rail 1 is cast with the anchor webs 2 in a structure made of concrete, which is not shown for the sake of simplicity. Then the formwork component 10 can be removed from the anchor rail 1, the fixing elements 11 remaining on the formwork component 10 with the retaining bracket 20 on the left side when removing the formwork component 10 and a flange 22 from a central section 21 of the retaining bracket via a predetermined breaking point 24 20 is separated. As a result, the fixing elements in the form of nails can be removed from the concrete structure.
Bei dem Haltebügel 20 auf der rechten Seite in Figur 3A ist zu erkennen, dass das Fixierelement 11 durch das Schalungsbauteil 10 nicht abgenommen wird und optional nun entfernt werden kann. In the case of the retaining bracket 20 on the right-hand side in FIG. 3A it can be seen that the fixing element 11 is not removed by the formwork component 10 and can optionally now be removed.
In den Figuren 4A bis 4D ist der Haltebügel 20 in Detail gezeigt. Der Haltebügel 20 ist als Formkörper aus Kunststoff hergestellt, kann aber auch aus einem an deren Material bestehen. Der Haltebügel 20 umfasst einen mittleren bügelför migen Abschnitt, der die Ankerschiene 1 in der montierten Position übergreift. Auf der Innenseite des bügelförmigen Abschnittes ist ein Steg oder Vorsprung 23 ausgebildet, der in eine Nut oder Aufnahme an der Ankerschiene 1 einfüg- bar ist, um die Ankerschiene gegen ein Verschieben zu sichern und um den Haltebügel 20 klemmend oder rastend vorzufixieren. Von dem mittleren bügel förmigen Abschnitt 21 erstrecken sich an beiden Seiten Flansche 22, die im Wesentlichen plattenförmig ausgebildet sind und über eine Sollbruchstelle 24 mit dem mittleren Abschnitt 21 verbunden sind. Die Sollbruchstelle 24 kann durch eine Materialschwächung, also eine Reduzierung des Materialquerschnit tes, hergestellt sein, beispielsweise durch Reduzierung der Dicke oder durch eine Perforation, so dass der Flansch 22 sicher von dem mittleren Abschnitt 21 abgetrennt werden kann. An dem mittleren Abschnitt 21 ist eine Verstärkungs strebe 25 ausgebildet, die im Bereich benachbart zu der Sollbruchstelle 24 ver stärkt. The retaining bracket 20 is shown in detail in FIGS. 4A to 4D. The retaining bracket 20 is made as a molded body made of plastic, but can also consist of one of their material. The retaining bracket 20 comprises a central bügelför shaped section which overlaps the anchor rail 1 in the assembled position. On the inside of the bow-shaped section, a web or projection 23 is formed, which can be inserted into a groove or receptacle on the anchor rail 1. bar is to secure the anchor rail against displacement and to pre-fix the retaining bracket 20 by clamping or locking. From the middle bow-shaped section 21, flanges 22 extend on both sides, which are essentially plate-shaped and are connected to the middle section 21 via a predetermined breaking point 24. The predetermined breaking point 24 can be produced by weakening the material, that is to say by reducing the material cross section, for example by reducing the thickness or by a perforation, so that the flange 22 can be securely separated from the central section 21. On the central portion 21, a reinforcement strut 25 is formed, which strengthens ver in the area adjacent to the predetermined breaking point 24.
An dem Haltebügel 20 kann ferner eine Markierung 26 oder Typenkennzeich nung vorgesehen sein, die beispielsweise Informationen darüber enthält, wel che Ankerschiene 1 in dem Baukörper vergossen wurde. On the retaining bracket 20, a marking 26 or type identification can also be provided, which contains, for example, information about wel che anchor rail 1 was potted in the structure.
Im Bereich der Flansche 22 kann an der Oberseite eine Profilierung zur Ver hinderung des Abrutschens des Fixierelementes, wie eine Riffelung, Rasterung oder ein Lochmuster, ausgebildet. Eine solche Profilierung kann auch an dem bügelförmigen mittleren Abschnitt 21 vorgesehen sein. In the area of the flanges 22, a profiling to prevent the fixing element from slipping off, such as a corrugation, grid or a hole pattern, can be formed on the upper side. Such a profile can also be provided on the bow-shaped central section 21.
In Figur 5 ist eine Einheit aus einem Schalungsbauteil 10, beispielsweise einer Holzwerkstoffplatte, und zwei Ankerschienen 1 gezeigt. Eine erste Ankerschie ne 1 ist bereits durch zwei Haltebügel 20 an dem Schalungsbauteil 10 fixiert, wobei beide Haltebügel 20 über Fixierelemente 11 in Form von Nägeln an dem Schalungsbauteil 10 gehalten sind, die in den Flanschen 22 eingebracht sind. Um die zweite Ankerschiene 1 fluchtend zu der ersten Ankerschiene 1 ausrich- ten zu können, ist ein Haltebügel 20 im Stoßbereich angeordnet und überdeckt eine Stirnseite der ersten Ankerschiene 1. Dadurch kann eine Stirnseite der zweiten Ankerschiene 1 unter den schon fixierten Haltebügel 20 eingeschoben werden, wie dies durch den Pfeil 30 schematisch dargestellt ist. Dadurch las sen sich auf einfache Weise zwei Ankerschienen 1 fluchtend ausrichten. In Figure 5, a unit of a formwork component 10, for example a wood-based panel, and two anchor rails 1 is shown. A first anchor rail 1 is already fixed to the formwork component 10 by two retaining brackets 20, with both retaining brackets 20 being held on the formwork component 10 by means of fixing elements 11 in the form of nails which are introduced into the flanges 22. In order to be able to align the second anchor rail 1 in alignment with the first anchor rail 1, a retaining bracket 20 is arranged in the joint area and covers an end face of the first anchor rail 1. As a result, an end face of the second anchor rail 1 can be pushed under the retaining bracket 20 that has already been fixed, as shown schematically by arrow 30. As a result, two anchor rails 1 can be aligned in a simple manner.
In den dargestellten Ausführungsbeispielen ist jeder Haltebügel mit zwei Flan schen 22 versehen, die jeweils über eine Sollbruchstelle 24 mit einem mittleren Abschnitt 21 verbunden sind. Es ist optional möglich, nur einen der Flansche 22 über ein Fixierelement an einem Schalungsbauteil 10 zu fixieren, um eine Ankerschiene 1 an dem Schalungsbauteil 10 festzulegen. Der Haltebügel 20 kann statt als Formkörper aus Kunststoff auch aus anderen Materialien, wie Metall, Pappe, Papier oder einer Kunststofffolie oder einem Vliesstoff, hergestellt sein. In the illustrated embodiments, each retaining bracket is provided with two flan's 22, which are each connected to a central section 21 via a predetermined breaking point 24. It is optionally possible to fix only one of the flanges 22 to a formwork component 10 via a fixing element in order to fix an anchor rail 1 on the formwork component 10. The retaining bracket 20 can also be made of other materials, such as metal, cardboard, paper or a plastic film or a nonwoven fabric, instead of being a molded body made of plastic.
