Description

Die vorliegende Erfindung betrifft eine Montageschiene gemäß dem Oberbegriff des Anspruches 1 und ein Bauwerk oder eine Bauwerkskomponente gemäß dem Oberbegriff des Anspruches 12.The present invention relates to a mounting rail according to the preamble of claim 1 and a building or a building component according to the preamble of claim 12.

Ankerschienen oder Montageschienen werden in der Bautechnik in Beton eingegossen oder eingebettet, so dass lediglich eine Oberseite oder ein Außenbereich eines Tragprofiles der Montageschiene frei zugänglich ist. Die Montageschiene leitet die in sie eingetragenen Kräfte durch einen Kontakt bzw. eine Verbindung mit dem umgebenden Beton in den Beton ein. Die Montageschiene weist dabei im Allgemeinen rückwärtig Anker auf. Zentrisch angreifende Kräfte werden dabei im Allgemeinen im Wesentlichen von den Ankern in den Beton eingeleitet. An der Ankerschiene angreifende Querkräfte werden von seitlichen Schenkeln des Tragprofils der Montageschiene in den Beton eingeleitet. Bei großen Querkräften kommt es zu Rissen und damit verbunden zu einer Bruchscholle an dem Beton. Die Risse breiten sich unter verschiedenen Winkeln im Beton aus, wobei mit dem Winkel das Volumen der ausgebrochenen Bruchscholle und damit verbunden die Auszugskraft steigt. Es tritt somit bei Querkräften ein relativ frühres Versagen der Montageschiene aufgrund eines flachen Risses bzw. einer kleinen Bruchscholle auf.Anchor rails or mounting rails are poured or embedded in the construction technique in concrete, so that only an upper side or an outer region of a supporting profile of the mounting rail is freely accessible. The mounting rail initiates the forces introduced into it by a contact or a connection with the surrounding concrete in the concrete. The mounting rail has generally backward anchor. Centrally attacking forces are generally introduced essentially by the anchors in the concrete. Transverse forces acting on the anchor rail are introduced into the concrete by lateral limbs of the supporting profile of the mounting rail. In the case of large transverse forces, cracks occur and, as a result, a broken block on the concrete. The cracks spread out at different angles in the concrete, with the angle increasing the volume of the broken fragment and thus the pull-out force. It thus occurs at shear forces on a relatively early failure of the mounting rail due to a shallow crack or a small broken clod.

Aus der DE 101 25 970 A ist eine Montageschiene bekannt, welche zwei in Längsrichtung verlaufende Halbschienen aufweist, die miteinander verbunden sind. Die Halbschienen sind dabei mittels Verbinder miteinander verbunden, wobei die Verbinder vorzugsweise als Klemmverbinder ausgebildet sind. Die Montageschiene ist zum Einbetonieren in eine Decke oder eine Wand eines Gebäudes vorgesehen.From the DE 101 25 970 A a mounting rail is known, which has two longitudinally extending half rails, which are interconnected. The half rails are connected to each other by means of connectors, wherein the connectors are preferably designed as a clamp connector. The mounting rail is intended to be embedded in a ceiling or wall of a building.

Die DE 35 31 998 A1 zeigt eine in Beton einbettbare, im Querschnitt als C-Profil gestaltete Ankerschiene mit am Schienenrücken vorstehenden Ankern in Form von mindestens im Endbereich mit Gewinde ausgestatteten Bolzen, auf welches Gewinde die Muttern aufgeschraubt sind, welche die Ankerflügel bilden, wobei die einseitige Aufschraubstellung der Mutter blockiert ist.The DE 35 31 998 A1 shows an embeddable in concrete, designed in cross-section as a C-profile anchor rail with anchoring on the rail spine in the form of at least end-threaded with bolts on which thread the nuts are screwed, which form the wings, the one-sided Aufschraubstellung blocked the mother is.

Die DE 26 02 164 A1 beschreibt eine Ankerschiene, bei der Anerkelemente auf zwei gegenüberliegenden Längsseiten der Schiene angeordnet sind, so dass die Ankerelemente die Schiene teilweise abdecken.The DE 26 02 164 A1 describes an anchor rail, are arranged in the Anerkelemente on two opposite longitudinal sides of the rail, so that the anchor elements partially cover the rail.

Die US 4,700,923 beschreibt I-Träger, die so in Beton eingegossen werden, dass um die Träger herum betonfreie Ausnhemungen gebildet sind.The US 4,700,923 describes I-beams that are poured into concrete so that concrete-free Ausnhemungen are formed around the carrier.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Montageschiene zur Verfügung zu stellen, bei dem eine mögliche Bruchscholle groß ist, so dass von der Montageschiene große Kräfte aufgenommen werden können, und weiter darin, ein Bauwerk oder eine Bauwerkskomponente mit solch einer Montageschiene anzugeben.The object of the present invention is to provide a mounting rail in which a possible fragmentary block is large, so that large forces can be absorbed by the mounting rail, and further to specify a building or a building component with such a mounting rail.

Diese Aufgabe wird gelöst mit einer Montageschiene zum Einbetten in einen erhärtbaren Baustoff, z. B. Beton, mit einem Tragprofil und vorzugsweise einem Mittel zum Befestigen wenigstens eines Anbauteiles an der Montageschiene, so dass das Tragprofil außenseitig an einem Einbettbereich eine unmittelbare Verbindung mit dem erhärtbaren Baustoff aufweist, wobei an dem Tragprofil außenseitig an dem Einbettbereich eine Auflage befestigt ist, so dass das Tragprofil außenseitig an dem Einbettbereich teilweise keinen unmittelbaren Kontakt mit dem erhärtbaren Baustoff aufweist, wobei die Auflage kompressibel ist und aus Schaumstoff oder einem Gewebe aus Kunststoff gebildet ist.This object is achieved with a mounting rail for embedding in a hardenable building material, for. As concrete, with a support profile and preferably a means for attaching at least one attachment to the mounting rail, so that the support profile on the outside of a Einbettbereich a direct connection with the hardenable building material wherein on the support profile on the outside of the Einbettbereich a support is attached, so that the support profile outside of the Einbettbereich partially no direct contact with the hardenable building material, wherein the support is compressible and is formed of foam or a fabric made of plastic.

Die kompressible, vorzugsweise elastische, Auflage verhindert im Wesentlichen die Übertragung von Kräften von dem Tragprofil auf den Beton im Bereich der Auflage. Die Auflage ist dabei vorzugsweise an einem Endabschnitt des Tragprofiles im Bereich des Außenbereiches angeordnet, so dass dadurch die in den Baustoff einzuleitenden Kräfte, insbesondere Querkräfte, außerhalb der Oberfläche des Baustoffes in den erhärtbaren Baustoff in tieferen Schichten einleitbar sind. Eine Resultierende aus den in die Montageschiene eingeleiteten Kräften tritt damit in tieferen Baustoffschichten auf, so dass dadurch eine Bruchscholle mit einem größeren Volumen erreicht werden kann und in die Montageschiene damit größere Kräfte, insbesondere Querkräfte, eingeleitet werden können, ohne dass ein Versagen oder ein Bruch des erhärtbaren Baustoffes eintritt.The compressible, preferably elastic, support essentially prevents the transmission of forces from the support profile to the concrete in the region of the support. The support is preferably arranged at an end portion of the supporting profile in the region of the outer region, thereby thereby the forces to be introduced into the building material, in particular Transverse forces, outside of the surface of the building material in the hardenable building material in deeper layers can be introduced. A resultant of the introduced into the mounting rail forces thus occurs in deeper layers of building material, so that a fragmentary clod can be achieved with a larger volume and in the mounting rail so that larger forces, in particular lateral forces can be initiated without a failure or breakage the hardenable building material occurs.

In einer weiteren Ausgestaltung ist der erhärtbare Baustoff Mörtel oder ein, vorzugsweise mineralischer, Zuschlag, z. B. Kies oder Sand, mit einem Bindemittel, z. B. Zement oder Bitumen.In a further embodiment, the hardenable building material is mortar or a, preferably mineral, aggregate, z. As gravel or sand, with a binder, eg. As cement or bitumen.

In einer zusätzlichen Ausgestaltung endet die Auflage oberseitig an einem Außenbereich der Tragschiene oder mit einem Abstand von weniger als 5 cm, 3 cm oder 1 cm zu dem Außenbereich des Tragprofiles. Dadurch werden die von der Montageschiene aufgenommenen Kräfte in dem Beton im Wesentlichen in tieferen Schichten des Baustoffes eingeleitet, so dass dadurch eine Resultierende aus den von der Montageschiene aufgenommenen Kräften im Wesentlichen in tieferen Schichten des Baustoffes auftritt und dadurch eine größere Bruchscholle bedingt ist.In an additional embodiment, the support ends on the upper side at an outer region of the mounting rail or at a distance of less than 5 cm, 3 cm or 1 cm to the outer region of the supporting profile. As a result, the forces absorbed by the mounting rail are introduced into the concrete essentially in deeper layers of the building material, so that thereby a resultant of the forces absorbed by the mounting rail substantially in deeper layers of the building material occurs and thus a larger fragmentation block is conditional.

Insbesondere ist die Auflage stoffschlüssig, insbesondere mittels eines Klebstoffes, an dem Tragprofil befestigt und/oder die Auflage ist mehrteilig.In particular, the support is firmly bonded, in particular by means of an adhesive, attached to the support section and / or the support is in several parts.

In einer weiteren Ausgestaltung ist die Auflage außenseitig an dem Einbettbereich des Tragprofiles nur teilweise ausgebildet, so dass das Tragprofil nur teilweise keinen unmittelbaren Kontakt mit dem erhärtbaren Baustoff aufweist.In a further embodiment, the support is only partially formed on the outside of the embedding region of the support profile, so that the support profile only partially has no direct contact with the hardenable building material.

In einer ergänzenden Ausführungsform ist die Auflage in Richtung einer Längsachse der Montageschiene nur teilweise oder vollständig ausgebildet und/oder die Auflage ist senkrecht zu der Längsachse der Montageschiene nur teilweise oder vollständig ausgebildet und/oder der Einbettbereich weist in einer Richtung parallel zu der Längsachse eine Verbindung und keine Verbindung zu dem erhärtbaren Baustoff auf und/oder der Einbettbereich weist in einer Richtung senkrecht zu der Längsachse eine Verbindung und keine Verbindung zu dem erhärtbaren Baustoff auf.In a supplementary embodiment, the support in the direction of a longitudinal axis of the mounting rail is only partially or completely formed and / or the support is only partially or completely formed perpendicular to the longitudinal axis of the mounting rail and / or the embedding has a connection in a direction parallel to the longitudinal axis and no Connection to the hardenable building material and / or the embedding area has a connection in a direction perpendicular to the longitudinal axis and no connection to the hardenable building material.

Vorzugsweise ist die Auflage außenseitig am Einbettbereich der Montageschiene streifenförmig angeordnet.Preferably, the support is arranged on the outside of the Einbettbereich the mounting rail strip-shaped.

Erfindungsgemäß ist die Auflage wenigstens teilweise, insbesondere vollständig, aus Schaumstoff, vorzugsweise Styropor, oder einem Gewebe aus Kunststoff gebildet.According to the invention the support is at least partially, in particular completely, made of foam, preferably polystyrene, or a fabric made of plastic.

Zweckmäßig ist das Tragprofil im Querschnitt im Wesentlichen C-förmig ausgebildet und/oder das Mittel umfasst zum Befestigen von Anbauteilen wenigstens einen Bolzen, Schraube, z. B. eine Hakenkopfschraube, eine Nut, einen Schlitz oder einen von dem Tragprofil umschlossenen Innenraum mit einer Öffnung als Nut oder Schlitz.Suitably, the support profile in cross-section is substantially C-shaped and / or the means comprises for attaching attachments at least one bolt, screw, z. As a hook head screw, a groove, a slot or enclosed by the support profile interior with an opening as a groove or slot.

In einer weiteren Ausführungsform weist die Montageschiene wenigstens einen, vorzugsweise mehrere, Anker zum Einbetten in den erhärtbaren Baustoff auf und vorzugsweise ist der wenigstens eine Anker an dem Tragprofil befestigt.In a further embodiment, the mounting rail has at least one, preferably a plurality, anchors for embedding in the hardenable building material, and preferably the at least one anchor is fastened to the support profile.

Insbesondere ist der wenigstens eine Anker im Wesentlichen senkrecht zu einer Streifenachse der als Streifen ausgebildeten Auflage ausgerichtet und/oder ist senkrecht zu der Längsachse der Montageschiene ausgerichtet.In particular, the at least one armature is aligned substantially perpendicular to a strip axis of the strip formed as a support and / or is aligned perpendicular to the longitudinal axis of the mounting rail.

In einer weiteren Ausgestaltung weist das Tragprofil eine oder zwei Schrägschenkel auf, die in einem spitzen Winkel, insbesondere mit einem Winkel zwischen 20° und 70°, zu einer Zentralebene ausgerichtet sind, wobei die Zentralebene senkrecht auf einer von der Öffnung aufgespannten Öffnungsebene steht und vorzugsweise die Längsachse der Montageschiene schneidet. Aufgrund der geneigten Schrägschenkel kann die von der Montageschiene aufgenommene Last in tiefere Schichten des Baustoffes eingeleitet werden, so dass damit eine weitere Vergrößerung der Bruchscholle verbunden ist und damit die von der Montageschiene aufnehmbaren Lasten bzw. Kräfte, insbesondere Querkräfte, weiter erhöht werden können.In a further embodiment, the support profile on one or two skew limbs, which are aligned at an acute angle, in particular at an angle between 20 ° and 70 °, to a central plane, wherein the central plane is perpendicular to an opening plane spanned by the opening and preferably the longitudinal axis of the mounting rail cuts. Due to the inclined skew leg recorded by the mounting rail load can be introduced into deeper layers of the building material, so that thus a further increase in the Fractional block is connected and thus the loads can be absorbed by the mounting rail or forces, in particular lateral forces, can be further increased.

In einer ergänzenden Variante besteht die Montageschiene, insbesondere das Tragprofil, wenigstens teilweise, insbesondere vollständig, aus Metall, z. B. Eisen, Stahl oder Aluminium, und/oder aus KunststoffIn a supplementary variant, the mounting rail, in particular the support profile, at least partially, in particular completely, made of metal, for. As iron, steel or aluminum, and / or plastic

Es kann ein Verfahren zum Einbetten einer in dieser Schutzrechtsanmeldung beschriebenen Montageschiene in einen erhärtbaren Baustoff, z. B. Beton oder Mörtel, vorgesehen sein, mit den Schritten: Anordnen der Montagschiene mit einem Tragprofil an der einzubettenden Stelle, Einbringen eines erhärtbaren Baustoffes in einen von einer Schalung begrenzten Raum, so dass das Tragprofil mit dem erhärtbaren Baustoff in Verbindung gebracht wird, Erhärten des Baustoffes, wobei der Baustoff dahingehend in den Raum eingebracht und vorzugsweise aus dem Raum entfernt wird, dass außenseitig an einem Einbettbereich des Tragprofiles der Baustoff nur teilweise, insbesondere unmittelbar, mit dem Tragprofil in Verbindung steht.It may be a method of embedding a mounting rail described in this patent application in a hardenable building material, eg. As concrete or mortar, be provided with the steps: arranging the mounting rail with a support section at the point to be embedded, introducing a hardenable building material in a limited space of a formwork, so that the supporting profile is associated with the hardenable building material, hardening the building material, wherein the building material is introduced into the room and preferably removed from the room, that on the outside of an embedding of the support profile of the building material only partially, in particular directly, is in communication with the support profile.

In einer Variante wird vor dem Anordnen der Montageschiene am Einbettbereich des Tragprofiles eine, vorzugsweise kompressible, Auflage befestigt. Aufgrund des Befestigens der Auflage an dem Tragprofil tritt im Bereich der Auflage der eingebrachte Baustoff nicht in unmittelbaren Kontakt oder Verbindung zu dem Tragprofil. Dadurch werden nach dem Erhärten des Betons von der Tragschiene im Bereich der Auflagen im Wesentlichen keine Kräfte in den Baustoff eingeleitet.In a variant, a, preferably compressible, pad is fixed before arranging the mounting rail on the embedding of the support section. Due to the attachment of the support to the support profile occurs in the area of the support of the introduced building material is not in direct contact or connection to the support profile. As a result, substantially no forces are introduced into the building material after hardening of the concrete from the mounting rail in the area of the supports.

In einer weiteren Ausgestaltung werden vor dem Einbringen des Baustoffes am Einbettbereich des Tragprofiles teilweise Füllkörper angelegt und nach dem Einbringen und/oder Erhärten des Baustoffes werden die Füllkörper entfernt, so dass eine Ausnehmung zwischen dem Tragprofil und dem Baustoff gebildet wird und/oder nach dem Einbringen oder Erhärten des Baustoffes wird der Baustoff im Bereich des Tragprofiles teilweise entfernt, so dass eine Ausnehmung zwischen dem Tragprofil und dem Baustoff gebildet wird und/oder die Montageschiene wird dahingehend, insbesondere zu hoch, an der einzubettenden Stelle angeordnet, dass nach dem Einbringen des Baustoffes der Einbettbereich des Tragprofiles nur teilweise, insbesondere nur in einem unteren Bereich, mit dem Baustoff in Verbindung steht.In a further embodiment, partial fillers are applied before the introduction of the building material at Einbettbereich the support section and after introduction and / or hardening of the building material, the filler are removed, so that a recess between the support profile and the building material is formed and / or after insertion or hardening of the building material, the building material is partially removed in the area of the supporting profile, so that a recess between the support profile and the building material is formed and / or the mounting rail is to the effect, especially too high, arranged at the point to be embedded, that after the introduction of the building material of the embedding of the support section only partially, especially only in a lower area, communicates with the building material.

Die Erfindung umfasst auch ein Bauwerk oder eine Komponente, z. B. Wand oder Decke, des Bauwerkes aus einem erhärtbaren Baustoff mit einer in den Baustoff eingebetteten Montageschiene, wobei die Montageschiene als eine erfindungsgemäße Montageschiene ausgebildet ist. Das Bauwerk oder die Komponente des Bauwerkes kann mit einem in dieser Schutzrechtsanmeldung beschriebenen Verfahren hergestellt sein.The invention also includes a building or a component, e.g. As wall or ceiling of the building of a hardenable building material with an embedded in the building material mounting rail, wherein the mounting rail is formed as a mounting rail according to the invention.

In Fig. 1 ist eine aus dem Stand der Technik bekannte Montageschiene 1 oder Ankerschiene 1 dargestellt. Die Montageschiene 1 besteht aus einem Tragprofil 2 aus Metall, insbesondere Stahl oder Aluminium. An einem unteren, in Fig. 1 horizontal ausgerichtetem Schenkel des Tragprofiles 2 ist ein Anker 15 befestigt. Neben dem oben beschriebenen horizontal ausgerichteten Schenkel des Tragprofiles 2 weist das Tragprofil 2 auch zwei vertikal ausgerichtete Schenkel auf. Am oberen Ende der vertikal ausgerichteten Schenkel des Tragprofiles 2 sind zwei horizontal ausgerichtete Streifenschenkel 22 vorhanden. Die Schenkel und der Streifenschenkel 22 des Tragprofiles 2 sind dabei im Wesentlichen rechteckförmig zueinander ausgerichtet. Außenseitig stehen der untere im Wesentlichen horizontal ausgerichtete Schenkel und die beiden vertikal ausgerichteten Schenkel des Tragprofiles 2 an einem Einbettbereich 6 in unmittelbarer Verbindung mit Beton 5 als erhärtbaren Baustoff 4, z. B. als Wand eines Bauwerkes. Damit stellen diese Schenkel außenseitig den Einbettbereich 6 des Tragprofiles 2 zur Verfügung. Die beiden Streifenschenkel 22 stehen an der Oberseite 7 nicht mit dem Beton 5 in Verbindung, d. h. bilden einen Außenbereich 7 oder eine Oberseite 7 des Tragprofiles 2. Das Tragprofil 2 schließt einen Innenraum 17 ein. In dem Innenraum 17 kann eine Hammerkopft- oder Hakenkopfschraube 18 als Mittel 3 zum Befestigen von nicht dargestellten Anbauteilen fixiert werden.In Fig. 1 a known from the prior art mounting rail 1 or anchor rail 1 is shown. The mounting rail 1 consists of a support section 2 made of metal, in particular steel or aluminum. At a lower, in Fig. 1 horizontally aligned leg of the support section 2, an anchor 15 is attached. In addition to the above-described horizontally oriented legs of the support section 2, the support section 2 also has two vertically oriented legs. At the upper end of the vertically oriented legs of the support section 2, two horizontally aligned strip legs 22 are present. The legs and the strip leg 22 of the support profile 2 are aligned substantially rectangular to each other. On the outside are the lower substantially horizontally oriented leg and the two vertically oriented legs of the support section 2 at a Einbettbereich 6 in direct connection with concrete 5 as hardenable building material 4, z. B. as a wall of a building. Thus, these legs outside the embedding 6 of the support section 2 available. The two strip legs 22 are not connected to the top 5 with the concrete 5 in connection, ie form an outside area 7 or an upper side 7 of the support section 2. The support section 2 includes an interior space 17 a. In the interior 17, a hammerhead or hook-headed screw 18 can be fixed as a means 3 for fixing attachments, not shown.

Dadurch ist es möglich, dass von der Montageschiene 1 eine Last L, welche in Fig. 1 mit einem Pfeil dargestellt ist, aufgenommen werden kann. Die Last L kann dabei - wie in Fig. 1 dargestellt - in horizontaler Richtung angreifen; die Last L kann aber auch als horizontale Komponente einer unter einem Winkel von 0° bis 90° angreifenden Last bzw. Kraft verstanden werden. Dies führt zu einer Resultierenden R als resultierenden Kraft in dem Beton 5. Die Resultierende R bzw. die an dem rechten vertikal ausgerichteten Schenkel des Tragprofiles 2 auf den Beton 5 wirkenden Kräfte werden dabei auch am oberen Betonrand in den Beton 5 eingeleitet, so dass aufgrund der sich ausbreitenden Risse 19 eine Bruchscholle 20 entsteht. Damit können von der Montageschiene 1 nur geringe Kräfte, insbesondere Querkräfte, in den Beton 5 eingeleitet werden.This makes it possible that of the mounting rail 1, a load L, which in Fig. 1 is shown with an arrow can be recorded. The load L can - as in Fig. 1 shown - attack in a horizontal direction; However, the load L can also be understood as a horizontal component of an attacking at an angle of 0 ° to 90 ° load or force. This results in a resultant R as a resultant force in the concrete 5. The resultant R or the force acting on the right vertically aligned leg of the support section 2 on the concrete 5 forces are introduced at the upper concrete edge in the concrete 5, so that due the spreading cracks 19 a broken block 20 is formed. Thus, only small forces, in particular lateral forces, can be introduced into the concrete 5 from the mounting rail 1.

In den Fig. 2 bis 11 ist eine erfindungsgemäße Montageschiene 1 dargestellt. Die in Fig. 2 dargestellte, in den Beton 5 eingebettete Montageschiene 1 ist im Wesentlichen wie die in Fig. 1 aus dem Stand der Technik bekannte Montageschiene 1 aufgebaut, wobei jedoch das Tragprofil 2 eine andere Geometrie aufweist und ferner an dem Tragprofil 2 kompressible, vorzugsweise elastische, Auflagen 8 befestigt sind. Das Tragprofil 2 weist einen horizontal ausgerichteten Schenkel mit daran angeordneten Ankern 15 auf. An diesen, horizontal ausgerichteten Schenkel des Tragprofiles 2 schließen zwei Schrägschenkel 16 an und an die Schrägschenkel 16 schließen sich zwei vertikal ausgerichtete Schenkel des Tragprofiles 2 wiederum an. In analoger Weise zu dem Tragprofil 2 in Fig. 1 schließen sich an diese beiden vertikal ausgerichteten Schenkel des Tragprofiles 2 jeweils zwei Streifenschenkel 22 an der Oberseite 7 des Tragprofiles 2 an. An den beiden vertikal ausgerichteten Schenkeln des Tragprofiles 2 sind außenseitig am Einbettbereich 6 die kompressiblen Auflagen 8 angeklebt. Die Auflagen 8 sind dabei streifenförmig ausgebildet und weisen als Schaumstoffstreifen aus Kunststoff eine Höhe von 0,5 mm bis 10 mm, vorzugsweise von 1,5 mm bis 5 mm auf. Die Dicke der Auflage 8 liegt dabei insbesondere in einem Bereich zwischen 0,1 mm und 10 mm. Die Länge der streifenförmigen Auflage 8 entspricht dabei der Länge des Tragprofiles 2 (Fig. 5). Abweichend hiervon kann die Auflage 8 auch in seiner Längsausdehnung, d. h. in einer Ausdehnung senkrecht zu der Zeichenebene von Fig. 2, oder in Richtung einer Längsachse 9 der Montageschiene 1 nur abschnittsweise ausgebildet sein (Fig. 6). Beim Aufbringen der Last L als Querkraft auf das Tragprofil 2 wird aufgrund der leichten Verformbarkeit der Auflage 8 von dem Tragprofil 2 im Bereich der Auflage 8 im Wesentlichen keine Kraft in den Beton 5 eingeleitet. Dadurch wird die von dem Tragprofil 2 aufgenommene Last L in den Beton 5 als Resultierende R im Wesentlichen von dem geneigten Schrägschenkel 16 in den Beton 5 eingeleitet. Die Resultierende R an dem Schrägschenkel 16 ist dabei im Gegensatz zu der Resultierenden R im Stand der Technik gemäß Fig. 1 nicht horizontal, sondern nach unten geneigt ausgerichtet, so dass dadurch auch die Risse 19 bei einem möglichen Versagen des Betons 5 nicht flach im Beton verlaufen sondern geneigt mit einem Winkel von ungefähr 45° zu einer Horizontalen ausgerichtet sind (Fig. 2). Hierdurch wird die Bruchfläche und damit das Volumen der Bruchscholle vergrößert, was zu einer Anhebung der Auszugskraft führt. Weitere auf den Baustoff 5 wirkende Resultierende R sind in Fig. 2 nicht dargestellt, jedoch erforderlich damit ein geschlossenes Kraftdiagramm, z. B. ein Kraftdreieck, für ein Kräftegleichgewicht entsteht; diese nicht dargestellte(n) Resultierende(n) R, welche z. B. der Anker 15 in den Baustoff 4 einleitet, haben jedoch auf die Größe der Bruchscholle 20 im Wesentlichen keine Wirkung. Somit vergrößert sich die Bruchscholle 20 des Betons 5 bei einem möglichen Versagen, so dass dadurch aufgrund der großen Bruchscholle 20 von dem Tragprofil 2 größere Lasten L aufgenommen werden können. Die von dem Tragprofil 2 in den Beton 5 eingeleiteten Kräfte als Resultierende R werden somit im Wesentlichen unterhalb eines oberseitennahen Bereiches des Betons 5 in tieferen Schichten des Betons 5 geneigt eingeleitet. Dadurch kann die Bruchlast des Betons 5 erhöht werden und damit insgesamt die Tragfähigkeit der Montageschiene 1 vergrößert werden.In the Fig. 2 to 11 a mounting rail 1 according to the invention is shown. In the Fig. 2 illustrated, embedded in the concrete 5 mounting rail 1 is essentially as in Fig. 1 constructed from the prior art mounting rail 1, but wherein the support section 2 has a different geometry and further on the support section 2 compressible, preferably elastic, pads 8 are attached. The support profile 2 has a horizontally oriented leg with anchors 15 arranged thereon. At these, horizontally oriented legs of the support section 2 close to two skew legs 16 and the bevel leg 16 close two vertically aligned legs of the support section 2 turn on. In an analogous manner to the support profile 2 in Fig. 1 close to these two vertically oriented legs of the supporting profile 2 in each case two strip legs 22 on the top 7 of the support section 2 at. At the two vertically oriented legs of the support profile 2, the compressible supports 8 are glued to the outside of the embedding area 6 on the outside. The pads 8 are strip-shaped and have as plastic foam strips a height of 0.5 mm to 10 mm, preferably from 1.5 mm to 5 mm. The thickness of the support 8 is in particular in a range between 0.1 mm and 10 mm. The length of the strip-shaped support 8 corresponds to the length of the supporting profile 2 ( Fig. 5 ). Notwithstanding this, the support 8 in its longitudinal extent, ie in a Extension perpendicular to the drawing plane of Fig. 2 , or only in sections in the direction of a longitudinal axis 9 of the mounting rail 1 ( Fig. 6 ). When applying the load L as a lateral force on the support section 2 substantially no force is introduced into the concrete 5 due to the easy deformability of the support 8 of the support section 2 in the region of the support 8. As a result, the load L received by the support profile 2 is introduced into the concrete 5 as the resultant R essentially from the inclined beveled leg 16 into the concrete 5. The resultant R on the skew leg 16 is in contrast to the resultant R in the prior art according to Fig. 1 not oriented horizontally, but inclined downwards, so that the cracks 19 are not flat in the concrete in case of a possible failure of the concrete 5 but are inclined at an angle of approximately 45 ° to a horizontal ( Fig. 2 ). As a result, the fracture surface and thus the volume of the fractured block is increased, which leads to an increase in the pull-out force. Other resultant on the building material 5 Resulting R are in Fig. 2 not shown, but required so that a closed power graph, z. B. a force triangle, arises for a balance of power; these not shown (n) Resultierende (n) R, which z. B. introduces the anchor 15 in the building material 4, however, have on the size of the fragmentary clod 20 essentially no effect. Thus, the fracture block 20 of the concrete 5 increases in the event of a possible failure, so that larger loads L can thereby be absorbed by the support profile 2 due to the large fracture block 20. The forces introduced by the support profile 2 into the concrete 5 as resultant R are thus introduced inclined substantially below a region near the top of the concrete 5 in deeper layers of the concrete 5. As a result, the breaking load of the concrete 5 can be increased and thus the overall load capacity of the mounting rail 1 can be increased.

Die Geometrie des Tragprofils 2 der in Fig. 2 dargestellten Montageschiene 1 weist zwischen den beiden Streifenschenkeln 22 eine Öffnung 12 auf. Die Öffnung 12 spannt dabei eine Öffnungsebene 13 auf. Die Öffnung 12 ist dabei als Nut 11 oder als Schlitz 10 ausgebildet und senkrecht auf der Öffnungsebene 13 steht eine Zentralebene 14, welche auch die Längsachse 9 des Tragprofiles 2 schneidet. Die Längsachse 9 des Tragprofiles 2 bzw. der Montageschiene 1 steht dabei senkrecht auf der Zeichenebene von Fig. 2. Die beiden Schrägschenkel 16 sind dabei in einem Winkel von ungefähr 45° zu der Zentralebene 14 ausgerichtet.The geometry of the supporting profile 2 of in Fig. 2 illustrated mounting rail 1 has between the two strip legs 22 an opening 12. The opening 12 spans an opening plane 13. The opening 12 is formed as a groove 11 or as a slot 10 and perpendicular to the Opening plane 13 is a central plane 14, which also intersects the longitudinal axis 9 of the support section 2. The longitudinal axis 9 of the support section 2 and the mounting rail 1 is perpendicular to the plane of Fig. 2 , The two skew legs 16 are aligned at an angle of approximately 45 ° to the central plane 14.

Der Beton 5 steht lediglich an dem unteren vertikal ausgerichteten Schenkel des Tragprofiles 2 und an den beiden Schrägschenkeln 16 in unmittelbarem Kontakt am Einbettbereich 6 mit dem Tragprofil 2. Am oberen vertikal ausgerichteten Schenkel des Tragprofiles 2 besteht keine unmittelbare Verbindung zwischen dem Tragprofil 2 und dem Beton 5, weil zwischen dem Tragprofil 2, d. h. dem vertikalen Schenkel des Tragprofiles 2, und dem Beton 5 die Auflage 8 angeordnet ist.The concrete 5 is only on the lower vertically oriented leg of the support section 2 and on the two skew legs 16 in direct contact with the embedding 6 with the support section 2. At the upper vertically oriented leg of the support section 2 there is no direct connection between the support section 2 and the concrete 5, because between the support profile 2, d. H. the vertical leg of the support section 2, and the concrete 5, the support 8 is arranged.

In Fig. 3 ist das in Fig. 2 dargestellte Tragprofil 2 bzw. die Montageschiene 1 ohne der Einbettung in den Beton 5 dargestellt und in der gleichen Weise ist in Fig. 4 ein zweites Ausführungsbeispiel der Montageschiene 1 ohne Einbettung in den Beton 5 abgebildet. In den Fig. 5 und 6 sind dabei Seitenansichten der Montageschienen 1 gemäß dem ersten Ausführungsbeispiel in Fig. 2 und 3 und dem zweiten Ausführungsbeispiel in Fig. 4 abgebildet. Die in den Fig. 3 und 4 dargestellten Montageschienen 1 stellen somit einen Schnitt senkrecht zu der Zeichenebene von Fig. 5 und 6 dar. In den in den Fig. 5 und 6 dargestellten Seitenansichten der Montageschiene 1 ist in Fig. 5 die streifenförmige Auflage 8 als durchgehender Streifen ausgebildet, so dass die Länge des Streifens als Auflage 8 der Länge des Tragprofiles 2 entspricht und damit die Auflage in Richtung der Längsachse 9 der Montageschiene 1 vollständig ausgebildet ist. In Fig. 6 ist die Auflage 8 lediglich abschnittsweise in Richtung der Längsachse 9 an dem Tragprofil 2 ausgebildet, so dass die Auflage 8 in Richtung der Längsachse 9 nur teilweise vorhanden ist. Darüber hinaus ist in einer Umfangsrichtung an dem Einbettbereich 6 des Tragprofiles 2 oder senkrecht zu der Längsachse 9 der Montageschiene 1 in Fig. 5 und 6 bzw. in Fig. 3 und 4 die Auflage 8 nur teilweise ausgebildet.In Fig. 3 is that in Fig. 2 shown support profile 2 and the mounting rail 1 without the embedding in the concrete 5 shown and in the same way is in Fig. 4 a second embodiment of the mounting rail 1 without embedding in the concrete 5 shown. In the Fig. 5 and 6 are side views of the mounting rails 1 according to the first embodiment in Fig. 2 and 3 and the second embodiment in Fig. 4 displayed. The in the 3 and 4 shown mounting rails 1 thus represent a section perpendicular to the plane of Fig. 5 and 6 In the in the Fig. 5 and 6 shown side views of the mounting rail 1 is in Fig. 5 the strip-shaped support 8 is formed as a continuous strip, so that the length of the strip as a support 8 corresponds to the length of the support profile 2 and thus the support in the direction of the longitudinal axis 9 of the mounting rail 1 is completely formed. In Fig. 6 the support 8 is only partially formed in the direction of the longitudinal axis 9 on the support section 2, so that the support 8 in the direction of the longitudinal axis 9 is only partially present. In addition, in a circumferential direction on the embedding 6 of the support section 2 or perpendicular to the longitudinal axis 9 of the mounting rail 1 in Fig. 5 and 6 or in 3 and 4 the edition 8 only partially formed.

In Fig. 7 ist die Montageschiene 1 in einem dritten Ausführungsbeispiel als Querschnitt dargestellt. Die Geometrie des Tragprofiles 2 ist dabei im Wesentlichen rechteckförmig ausgebildet mit einem unteren horizontal ausgerichteten Schenkel, zwei vertikal ausgerichteten Schenkeln und zwei Streifenschenkel 22 an der Öffnung 12. An den beiden vertikal ausgerichteten Schenkeln des Tragprofiles 2 sind außenseitig am Einbettbereich 6 des Tragprofiles 2 die Auflagen 8 befestigt. Bezüglich des vertikalen Schenkels des Tragprofiles 2 ist dabei die Auflage 8 an dem vertikalen Schenkel des Tragprofiles 2 in einer Richtung senkrecht zu der Längsachse 9 der Montageschiene 1 vollständig ausgebildet.In Fig. 7 the mounting rail 1 is shown in a third embodiment as a cross section. The geometry of the support section 2 is substantially rectangular in shape with a lower horizontally oriented legs, two vertically aligned legs and two strip legs 22 at the opening 12. On the two vertically aligned legs of the support section 2 are on the outside of the embedding 6 of the support section 2, the conditions 8 attached. With respect to the vertical leg of the support section 2 while the support 8 is completely formed on the vertical leg of the support section 2 in a direction perpendicular to the longitudinal axis 9 of the mounting rail 1.

Das vierte in Fig. 8 abgebildete Ausführungsbeispiel der Montageschiene 1 unterscheidet sich von dem dritten Ausführungsbeispiel gemäß Fig. 7 dadurch, dass an den beiden vertikalen Schenkeln des Tragprofiles 2 die Auflagen 8 lediglich an der unteren Hälfte der vertikalen Schenkel des Tragprofiles 2 festgeklebt sind. Damit sind die Auflagen 8 bezüglich der vertikalen Schenkel des Tragprofiles 2 im vierten Ausführungsbeispiel senkrecht zu der Längsachse 9 der Montageschiene 1 nur teilweise ausgebildet. Die Ausdehnung der Auflagen 8 gemäß den in Fig. 7 und 8 dargestellten dritten und vierten Ausführungsbeispiel der Montageschiene 1 kann dabei senkrecht zu der Zeichenebene von Fig. 1, d. h. in einer Richtung parallel zu der Längsachse 9 der Montageschiene 1 vollständig oder nur teilweise ausgebildet sein, d. h. in analoger Weise zu der Ausführung der Auflage 8 in den Abbildungen 5 und 6.The fourth in Fig. 8 illustrated embodiment of the mounting rail 1 differs from the third embodiment according to Fig. 7 in that on the two vertical legs of the support profile 2, the supports 8 are glued only to the lower half of the vertical leg of the support section 2. Thus, the supports 8 with respect to the vertical legs of the support profile 2 in the fourth embodiment are formed perpendicular to the longitudinal axis 9 of the mounting rail 1 only partially. The extension of the supports 8 according to the in FIGS. 7 and 8 illustrated third and fourth embodiment of the mounting rail 1 can be perpendicular to the plane of Fig. 1 , ie, be formed completely or only partially in a direction parallel to the longitudinal axis 9 of the mounting rail 1, ie in an analogous manner to the embodiment of the support 8 in Figures 5 and 6.

In Fig. 9 ist ein fünftes Ausführungsbeispiel der Montageschiene 1 dargestellt. In dem in Fig. 9 dargestellten fünften Ausführungsbeispiel der Montageschiene 1 weist die Auflage 8 dabei eine unterschiedliche Dicke auf, so dass die Auflage 8 keilförmig am Beton 5 endet. Die Auflage 8 weist dabei an der Oberseite 7 der Montageschiene 1 eine größere Dicke auf als am unteren Ende der Auflage 8 am Beginn des Schrägschenkels 16 des Tragprofiles 2.In Fig. 9 a fifth embodiment of the mounting rail 1 is shown. In the in Fig. 9 illustrated fifth embodiment of the mounting rail 1, the support 8 has a different thickness, so that the support 8 ends wedge-shaped on the concrete 5. The support 8 has at the top 7 of the mounting rail 1 a greater thickness than at the lower end of the support 8 at the beginning of the oblique leg 16 of the support profile. 2

In Fig. 10 ist ein Querschnitt einer in Beton 5 eingebetteten Montageschiene 1 mit einer Ausnehmung 21 des Betons 5 an der Oberseite des Betons 5 dargestellt. Bei der Herstellung des Bauwerkes mit der Montageschiene 1 und dem erhärtbaren Baustoff 4 als Beton 5 wird zunächst die Montageschiene 1 an der einzubettenden Stelle angeordnet, beispielsweise entsprechend an einer Schalung befestigt. Anschließend wird in den von der Schalung eingeschlossenen Raum der Beton 5 eingebracht. Nach dem Einbringen des Betons 5 und der damit verbundenen Verbindung des Betons 5 mit dem gesamten Einbettbereich 6 des Tragprofiles 2 wird an den beiden vertikal ausgerichteten Schenkeln des Tragprofiles 2 der Beton 5 wieder entfernt, so dass sich die streifenförmige Ausnehmung 21 ausbildet und damit die beiden vertikalen Schenkel des Tragprofiles 2 nicht mehr in Verbindung mit dem Beton 5 stehen. Das Entfernen des Betons 5 kann dabei während oder nach dem Aushärten des Betons 5 durchgeführt werden. Das Herausarbeiten des Betons 5 an den Ausnehmungen 21 kann dabei beispielsweise schleifend mit einem Diamantwerkzeug, mit einer Fräse, bohrend, meißelnd oder durch eine Kombination der genannten Verfahren durchgeführt werden. Die Breite des Schlitzes liegt dabei in einem Bereich zwischen 0,5 mm und 20 mm, vorzugsweise im Bereich zwischen 1,5 mm und 5 mm. Die Höhe des Schlitzes, nämlich der Ausnehmung 21, entspricht dabei der Höhe des vertikalen Schenkels des Tragprofiles 2. Die Ausdehnung der Ausnehmung 21 senkrecht zu der Zeichenebene von Fig. 1 kann dabei entweder vollständig durchlaufend sein oder die Ausnehmung 21 ist an dem vertikalen Schenkel des Tragprofiles 2 senkrecht zu der Zeichenebene von Fig. 10, d. h. in einer Richtung parallel zu der Längsachse 9 des Tragprofiles 2, nur teilweise ausgebildet.In Fig. 10 is a cross section of an embedded in concrete 5 mounting rail 1 with a recess 21 of the concrete 5 at the top of the concrete 5 shown. In the manufacture of the building with the mounting rail 1 and the hardenable building material 4 as concrete 5, the mounting rail 1 is first arranged at the point to be embedded, for example, attached to a formwork accordingly. Subsequently, the concrete 5 is introduced into the space enclosed by the formwork. After the introduction of the concrete 5 and the associated connection of the concrete 5 with the entire embedding 6 of the support section 2, the concrete 5 is removed again at the two vertically oriented legs of the supporting section 2, so that the strip-shaped recess 21 is formed and thus the two vertical leg of the support section 2 no longer stand in conjunction with the concrete 5. The removal of the concrete 5 can be carried out during or after the curing of the concrete 5. The working out of the concrete 5 at the recesses 21 can be carried out, for example, grinding with a diamond tool, with a milling cutter, drilling, chiseling or by a combination of said methods. The width of the slot is in a range between 0.5 mm and 20 mm, preferably in the range between 1.5 mm and 5 mm. The height of the slot, namely the recess 21, corresponds to the height of the vertical leg of the support profile 2. The extension of the recess 21 perpendicular to the plane of Fig. 1 can either be completely continuous or the recess 21 is perpendicular to the vertical plane of the supporting profile 2 to the plane of Fig. 10 , ie, in a direction parallel to the longitudinal axis 9 of the support profile 2, only partially formed.

Abweichend von der oben beschriebenen Herstellungsweise für die Ausnehmung 21 kann die Ausnehmung 21 auch dadurch hergestellt werden, dass während des Einbringens des Betons 5 an den beiden vertikalen Schenkeln des Tragprofiles 2 ein nicht dargestellter Füllkörper angeordnet ist. Der Füllkörper kann dabei auch auf den vertikalen Schenkel des Tragprofiles 2 mittels Kleben befestigt sein. Nach dem Einbringen des Betons und dem teilweise oder vollständigen Erhärten des Betons 5 wird der nicht dargestellte Füllkörper wieder entfernt, so dass an dem Einbettbereich 6 des Tragprofiles 2 im Bereich der beiden vertikalen Schenkel die streifenförmige Ausnehmung 21 wiederum vorhanden ist. Auch auf diese Weise kann erreicht werden, dass am Tragprofil 2 in analoger Weise zu der Darstellung in Fig. 2 die Resultierende R aus der Last L in tieferen Schichten des Betons 5 geneigt nach unten in den Beton 5 eingeleitet wird. Dies bedingt eine große Bruchscholle 20 und von der Montageschiene 1 können große Lasten L, insbesondere Querkräfte, aufgenommen werden bei einer randnahen Einbindung der Montageschiene 1 in den Beton 5 bezüglich der Querkräfte.Notwithstanding the method of production described above for the recess 21, the recess 21 can also be produced in that during the introduction of the concrete 5 on the two vertical legs of the supporting profile 2, a packing, not shown, is arranged. The filler can also be attached to the vertical leg of the support section 2 by gluing. After the introduction of the concrete and the partial or complete hardening of the concrete 5 is the Not shown filling body removed again, so that the strip-shaped recess 21 is in turn present at the embedding 6 of the support section 2 in the region of the two vertical legs. Also in this way it can be achieved that on the support section 2 in an analogous manner to the illustration in Fig. 2 the resultant R from the load L in deeper layers of the concrete 5 is inclined downwards into the concrete 5 is introduced. This requires a large fragmentation block 20 and of the mounting rail 1, large loads L, in particular lateral forces are absorbed at a near-border integration of the mounting rail 1 in the concrete 5 with respect to the transverse forces.

In Fig.11 ist ein weiteres Ausführungsbeispiel zur Einbettung der Montageschiene 1 in den Beton 5 dargestellt. Die Montageschiene 1 ist dabei zu hoch in den Beton 5 eingebettet, so dass der Einbettbereich 6 des Tragprofiles 2 im Bereich der beiden vertikalen Schenkel des Tragprofiles 2 außerhalb des Betons 5 angeordnet ist. Damit sind lediglich die beiden Schrägschenkel 16 und der horizontal ausgerichtete Schenkel des Tragprofiles 2 in Verbindung mit dem Beton 5. Auch in dieser Ausgestaltung kann erreicht werden, dass die Resultierende R aus der Last L stärker geneigt nach unten in Richtung zu tieferen Schichten des Betons 5 in den Beton 5 eingeleitet werden kann und dadurch eine größere Bruchscholle 20 bedingt.In Figure 11 is a further embodiment for embedding the mounting rail 1 in the concrete 5 shown. The mounting rail 1 is embedded too high in the concrete 5, so that the embedding 6 of the support section 2 in the region of the two vertical legs of the support section 2 outside the concrete 5 is arranged. Thus, only the two skew legs 16 and the horizontally oriented legs of the support section 2 in conjunction with the concrete 5. Also in this embodiment can be achieved that the resultant R from the load L more inclined down towards deeper layers of the concrete. 5 can be introduced into the concrete 5 and thereby causes a larger fragmentation block 20.

Die verschiedenen Ausführungsbeispiele können miteinander kombiniert werden, sofern nichts Gegenteiliges erwähnt wird und/oder soweit es sinnvoll ist.The various embodiments may be combined with each other unless otherwise stated and / or as appropriate.

Insgesamt betrachtet sind mit der erfindungsgemäßen Montageschiene 1 wesentliche Vorteile verbunden. Die von der Montageschiene 1 mit dem Tragprofil 2 in den Baustoff 4 eingeleiteten Kräfte als Resultierende R aufgrund der auf die Montageschiene 1 wirkende Last L wird in tiefere Schichten geneigt in den Baustoff 4 eingeleitet, so dass dadurch eine große Bruchscholle 20 erzielt werden kann. Damit können von der Montageschiene 1 größere Kräfte als Last L aufgenommen werden. Dies ist insbesondere bei einer Einbindung der Montageschiene 1 randseitig in den Baustoff 4 mit angreifenden Querkräften als Last L von Vorteil. Bei der randseitigen Einbindung der Montageschiene 1 weist der Baustoff 4 von der Montageschiene 1 in Richtung der Querkraft bzw. der Last L zum Ende des Baustoffes 4 nur eine geringe Ausdehnung auf.Overall, significant advantages are associated with the mounting rail 1 according to the invention. The introduced from the mounting rail 1 with the support section 2 in the building material 4 forces resulting as R due to acting on the mounting rail 1 load L is inclined into deeper layers introduced into the building material 4, so that thereby a large fragmentation block 20 can be achieved. This allows greater forces to be absorbed by the mounting rail 1 as a load L. This is in particular with an integration of the mounting rail 1 edge in the building material 4 with attacking shear forces as a load L advantage. In the peripheral integration of the mounting rail 1, the building material 4 from the mounting rail 1 in the direction of the transverse force or the load L to the end of the building material 4 only a small extent.
