Description

Die Erfindung betrifft eine frei auskragende Stufe einer Treppe, wobei die Stufe an einem Bauteil eines Gebäudes angeordnet ist, wobei in der Stufe mindestens ein sich in Längsrichtung der Stufe erstreckender stangenförmiger Zuganker angeordnet ist, wobei durch den mindestens einen Zuganker die Stufe auf Druck vorgespannt ist, wobei die Stufe zur Aufnahme des mindestens einen stangenförmigen Zugankers ein sich in Längsrichtung der Stufe erstreckendes Sackloch aufweist, wobei der Zuganker in dem Sackloch verankert ist.The invention relates to a cantilevered step of a staircase, wherein the step is arranged on a component of a building, wherein in the step at least one extending in the longitudinal direction of the step bar-shaped tie rod is arranged, is biased by the at least one tie rod, the stage on pressure wherein the step for receiving the at least one bar-shaped tie rod has a blind hole extending in the longitudinal direction of the step, the tie rod being anchored in the blind hole.

Aus der DE 20 25 938 A1 ist eine Treppe mit freiliegenden Treppenstufen bekannt, wobei die Treppenstufen an ihren freiliegenden Enden durch z. B. Bolzen, Schrauben oder dergleichen lösbar verbunden sind. Die untereinander an ihrem freiliegenden Ende lösbar verbundenen Treppenstufen der Treppe sind darüber hinaus an ihrem anderen Ende lösbar an einem Träger angeordnet, der an einer Wand befestigt ist. Die jeweilige Konstruktion dient dazu verschlissene Treppenstufen austauschen zu können.From the DE 20 25 938 A1 is a staircase with exposed stairs known, the stairs at their exposed ends by z. B. bolts, screws or the like are releasably connected. The stair steps of the stairs, which are detachably connected to one another at their exposed end, are furthermore detachably arranged at their other end on a support which is fastened to a wall. The respective construction is used to replace worn stairs.

Treppen mit frei auskragenden Treppenstufen sind aus dem Stand der Technik hinreichend bekannt. So ist beispielsweise aus der DE 10 2005 035 560 B3 eine Treppenstufe einer Treppe bekannt, bei der die Stufe frei auskragend durch ein Gebäudeteil aufnehmbar ist, wobei zur Aufnahme der aus mehreren Glasschichten bestehenden Stufe an dem Gebäudeteil eine Befestigungsvorrichtung vorgesehen ist. Die Befestigungsvorrichtung umfasst Backen mit Spannmitteln, wobei die Spannmittel die Stufe zwischen den Backen eingespannt halten. Die Spannmittel können hierbei als Schraubbolzen ausgebildet sein.Stairs with cantilevered steps are well known in the art. For example, from the DE 10 2005 035 560 B3 a step of a staircase known, in which the step freely cantilevered by a building part is receivable, wherein for receiving the existing layer consisting of several layers of glass on the building part a fastening device is provided. The fastening device comprises jaws with clamping means, wherein the clamping means hold the step between the jaws clamped. The clamping means may be formed here as a bolt.

Die DE 195 03 582 C2 zeigt eine Spindeltreppe mit frei auskragend an der Spindel angeordneten nicht miteinander verbundenen Treppenstufen aus Naturstein. Eine jede dieser Treppenstufen besitzt zwei parallel zur Längsachse sich in der Treppenstufe erstreckende Bewehrungsstäbe, die an beiden Stirnseiten der Treppenstufe austreten. Endseitig weisen die Bewehrungsstäbe jeweils ein Gewinde zur Aufnahme einer Mutter auf, wobei die Muttern gegen die Stufe auf der Spindel verspannt werden. Die Anordnung solcher Bewehrungsstäbe in einer Natursteinstufe ist aus folgenden Gründen erforderlich. Naturstein kann hohen Druckkräften standhalten, wie dies auch bei Beton der Fall ist, ist allerdings nur in geringem Umfange auf Zug beanspruchbar. Durch die in der Treppenstufe angeordneten Bewehrungsstäbe, die gegen die Treppenstufe vorgespannt werden, wird die einzelne Treppenstufe durch die Bewehrungsstäbe auf Druck beansprucht. Bei Belastung der Treppenstufe wird nun aufgrund der Biegebeanspruchung der Stufe die Druckbeanspruchung der Stufe entsprechend dem auf der Stufe aufstehenden Gewicht abgebaut. Dieses Prinzip ist an sich wie dies bereits beschrieben wurde aus dem Stand der Technik hinreichend bekannt.The DE 195 03 582 C2 shows a spiral staircase with freely cantilevered arranged on the spindle unconnected steps made of natural stone. Each of these steps has two parallel to the longitudinal axis in the step extending reinforcing bars, which emerge at both ends of the step. The end of the reinforcing bars each have a thread for receiving a nut, wherein the nuts are braced against the step on the spindle. The arrangement of such reinforcing bars in a natural stone stage is required for the following reasons. Natural stone can withstand high compressive forces, as is the case with concrete, but can only be claimed to a limited extent on train. By the reinforcing bars arranged in the step, which are prestressed against the step be, the single step is claimed by the reinforcing bars on pressure. When loading the step, the compressive stress of the step is reduced due to the bending stress of the step corresponding to the weight standing on the step now. As already described, this principle is sufficiently known from the prior art.

Nachteilig hierbei ist, dass von außen die Bewehrungsstäbe, die sich parallel zur Längsachse der Stufe in der Stufe erstrecken, erkennbar sind. Zwar ist bekannt, im Bereich des freien stirnseitigen Endes einer Treppenstufe an die Bewehrungsstäbe Halterungen für das Geländer anzubringen, jedoch stört auch dies den optischen Gesamteindruck einer solchen Treppe. Dies auch insofern, als das Geländer häufig eher auf der Treppenstufe angebracht wird.The disadvantage here is that from the outside the reinforcing rods, which extend parallel to the longitudinal axis of the step in the stage, are recognizable. Although it is known to mount brackets for the railing in the region of the free end face of a step on the reinforcing bars, but this also disturbs the overall visual impression of such a staircase. This also insofar as the railing is often placed more on the step.

Aus der DE 3506329 A1 ist eine Stufe gemäß dem Oberbegriff des Anspruches 1 bekannt. Die Verankerung in der Stufe erfolgt dadurch, dass in das Sackloch der Stufe eine aushärtbare Masse eingebracht wird, in die ein Zuganker eingeschoben wird. Nach Aushärten der Masse wird auf das Ende des mit einem Gewinde versehenen Zugankers eine Mutter aufgesetzt und so die Stufe vorgespannt. Nachteilig hierbei ist, dass sich beim Anziehen der Mutter auf dem Zuganker gegen die Stirnseite der Stufe der Zuganker aus der ausgehärteten Masse lösen kann. In einem solchen Fall muss das Sackloch nochmals aufgebohrt werden, um den Zuganker erneut zu befestigen.From the DE 3506329 A1 is a step according to the preamble of claim 1 is known. The anchoring in the step takes place in that a hardenable mass is introduced into the blind hole of the step, into which a tie rod is inserted. After hardening of the mass, a nut is placed on the end of the threaded tie rod and thus biased the step. The disadvantage here is that when tightening the nut on the tie rod against the front side of the stage of the tie rod can be released from the hardened mass. In such a case, the blind hole must be drilled again to fix the tie rod again.

Die der Erfindung zugrunde liegende Aufgabe besteht demzufolge darin, bei einer frei auskragenden Stufe einer Treppe der eingangs genannten Art, den mindestens einen Zuganker in der Stufe derart anzubringen, dass er gegen die Stufe vorgespannt werden kann, ohne dass die Gefahr besteht, dass er ausreißt.The object underlying the invention is therefore, in a cantilevered step of a staircase of the type mentioned, the at least one tie rod in the stage to install such that it can be biased against the stage without the risk that he tears ,

Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, dass die Stufe zur Aufnahme des mindestens einen stangenförmigen Zugankers in dem Sackloch, eine in dem Sackloch verankerte Hülse mit einem Innengewinde zur Aufnahme des mit einem Außengewinde versehenen Zugankers aufweist.To achieve the object, the invention proposes that the stage for receiving the at least one rod-shaped tie rod in the blind hole, an anchored in the blind hole sleeve having an internal thread for receiving the externally threaded tie rod.

Hieraus wird deutlich, dass zunächst eine Hülse in das Sackloch eingeschoben wird, die Hülse im Inneren des Sackloches mit der Stufe verbunden wird, beispielsweise durch einen geeigneten Klebstoff, wie dies auch schon in Bezug auf die zuvor beschriebene Ausführungsform erwähnt worden ist. Im Einzelnen kann hierbei vorgesehen sein, dass die Hülse auf ihrem Außenumfang eine Verzahnung, insbesondere ein Gewinde aufweist, um eine stabile Verbindung zwischen der Hülse einerseits und dem sie umgebenden Material der Treppenstufe herzustellen.From this it is clear that first a sleeve is inserted into the blind hole, the sleeve is connected in the interior of the blind hole with the step, for example by a suitable adhesive, as has already been mentioned in relation to the embodiment described above. Specifically, it can be provided here that the sleeve on its outer circumference has a toothing, in particular a thread to produce a stable connection between the sleeve on the one hand and the surrounding material of the step.

Die Verspannung des mindestens einen in der Treppenstufe geführten Zugankers gegen die Treppenstufe selbst zur Erzeugung einer Druckkraft auf die Treppenstufe erfolgt durch eine auf der dem Bauteil zugewandten Stirnseite der Treppenstufe angeordneten Spannplatte, wobei der mindestens eine Zuganker im Bereich der Spannplatte ein Gewinde zur Aufnahme eines Spanngliedes aufweist, um den Zuganker gegen die Spannplatte vorzuspannen. Hieraus wird deutlich, dass der Zuganker auf Zug und korrespondierend hierzu die Stufe über die Spannplatte auf Druck beansprucht wird.The tension of the at least one guided in the step tie rod against the step itself to produce a compressive force on the step by a arranged on the component end face of the step arranged clamping plate, said at least one tie rod in the clamping plate a thread for receiving a tendon has to bias the tie rod against the clamping plate. From this it is clear that the tie rod to train and corresponding to the step on the clamping plate is subjected to pressure.

Im Einzelnen ist vorgesehen, dass die Spannplatte ein Senkloch zur Aufnahme einer Mutter aufweist, die auf dem Zuganker aufsitzt. Das Senkloch weist hierbei eine Tiefe auf, die mindestens der Höhe der Mutter entspricht, sodass bei entsprechender Länge des Zugankers, der Zuganker mit der Mutter plan zur Oberseite der Spannplatte abschließt.In detail, it is provided that the clamping plate has a countersunk hole for receiving a nut which rests on the tie rod. The countersunk hole in this case has a depth which corresponds at least to the height of the mother, so that with a corresponding length of the tie rod, the tie rod with the mother plan to the top of the clamping plate concludes.

Nach einem weiteren Merkmal der Erfindung ist die Spannplatte mit einer Ankerplatte verbunden, die der Befestigung am Bauteil des Gebäudes dient. Die Ankerplatte selbst, die mit der Spannplatte beispielsweise verschweißt ist, kann in dem Beton des Bauteils eingegossen sein, oder aber die Ankerplatte wird mit dem Bauteil, beispielsweise einer Wand, verdübelt.According to a further feature of the invention, the clamping plate is connected to an anchor plate which serves the attachment to the component of the building. The anchor plate itself, which is welded to the clamping plate, for example, may be cast in the concrete of the component, or the anchor plate is pegged to the component, such as a wall.

Durch die Anordnung eines Sackloches, das sich parallel zur Längsachse von der einen Stirnseite ausgehend in die Treppenstufe erstreckt, zur Aufnahme des mindestens einen Zugankers, wird nunmehr erreicht, dass die Bewehrung der Treppe von außen nicht sichtbar ist, denn an der Stirnseite der Stufe mit dem Sackloch ist die Stufe am Bauteil des Gebäudes, z. B. einer Wand, befestigt.By arranging a blind hole, which extends parallel to the longitudinal axis of the one end face, starting in the step, for receiving the at least one tie rod, is now achieved that the reinforcement of the stairs from the outside is not visible, because at the front of the stage with the blind hole is the step on the component of the building, z. B. a wall attached.

Anhand der Zeichnungen wird die Erfindung nachstehend beispielhaft näher erläutert.

Fig. 2
zeigt einen Schnitt gemäß der Linie II-II aus Fig. 1 in einer zweiten Ausführungsform;
With reference to the drawings, the invention will be explained in more detail below by way of example.
Fig. 1
schematically shows a arranged on a component of a building step in a plan view;
Fig. 2
shows a section along the line II-II Fig. 1 in a second embodiment;

Die mit 1 bezeichnete Treppenstufe ist an einem mit 2 bezeichneten Gebäudeteil angeordnet. Das Gebäudeteil 2 kann hierbei beispielsweise eine Beton- oder Ziegelwand eines Gebäudes sein. Denkbar ist ebenfalls die Anordnung der Treppenstufe an dem Mantel einer Spindel. Das heißt, die Spindel ist ebenfalls als ein Gebäudeteil im Sinne der Erfindung anzusehen. Gegenstand der Erfindung ist nunmehr die Anordnung der beiden als Zuganker 10 ausgebildeten Bewehrungsglieder in der Treppenstufe 1 (Fig. 1).The designated 1 step is located on a designated 2 part of the building. The building part 2 may in this case be, for example, a concrete or brick wall of a building. Also conceivable is the arrangement of the step on the shell of a spindle. That is, the spindle is also to be regarded as a building part within the meaning of the invention. The invention is now the arrangement of the two trained as tie rods 10 reinforcing elements in the stair step 1 ( Fig. 1 ).

Wie sich aus der Darstellung gemäß Fig. 2 ergibt, ist in dem Sackloch eine Hülse 15 angeordnet, wobei die Hülse 15 ein Innengewinde 15 a und ein Außengewinde 15 b aufweist. Die Hülse 15 wird hierbei durch einen Kleber, beispielsweise auf der Basis von einem Polyesterharz in dem Sackloch der Treppenstufe 1 verklebt. Die Hülse 15 dient der Aufnahme des Zugankers 10, der wiederum am hülsenseitigen Ende einen Gewindeansatz aufweist.As can be seen from the illustration according to Fig. 2 results, in the blind hole, a sleeve 15 is arranged, wherein the sleeve 15 has an internal thread 15 a and an external thread 15 b. The sleeve 15 is in this case glued by an adhesive, for example on the basis of a polyester resin in the blind hole of the stair step 1. The sleeve 15 serves to receive the tie rod 10, which in turn has a threaded projection on the sleeve-side end.

Für die Verspannung des Zugankers 10 gegen die Stufe 1 ist, wie sich dies aus der Darstellung gemäß Fig. 2 ergibt, eine Spannplatte 20 vorgesehen, wobei die Spannplatte 20 sich über die Fläche der Stirnseite der Stufe 1 erstreckt. Die Spannplatte weist für die Durchführung des Zugankers 10 eine Bohrung 21 auf, wobei der Zuganker an diesem Ende zumindest auch ein Gewinde 12 zur Aufnahme der mit 23 bezeichneten Mutter aufweist. Die Spannplatte 20 besitzt des Weiteren im Bereich der Bohrung 21 ein Senkloch 24, das der Aufnahme der Mutter 23 dient. Die Größe des Senkloches 24 und die Größe der Mutter korrespondieren auch insofern, als zwischen Senkloch und Mutter ein radialer Abstand vorgesehen ist, um Raum für den Ansatz eines Werkzeuges, beispielsweise einer Nuss zu haben. Nach Verspannung der Spannplatte 20 und des Zugankers gegen die Stufe wird an der Spannplatte 20 eine Ankerplatte 30 befestigt. Die Ankerplatte liegt plan auf der Spannplatte 20 auf, da die Höhe der Mutter geringer ist, als die Tiefe des Senkloches. Die Ankerplatte 30 kann beispielsweise mit der Spannplatte verschweißt oder auch verschraubt sein. Die Ankerplatte 30 wird in dem Bauteil, beispielsweise wenn es sich um eine Betonwand handelt, eingegossen oder mit der Wand verdübelt.For the tension of the tie rod 10 against the stage 1, as can be seen from the illustration in FIG Fig. 2 results, a clamping plate 20 is provided, wherein the clamping plate 20 extends over the surface of the end face of the stage 1. The clamping plate has a bore 21 for the passage of the tie rod 10, wherein the tie rod at this end has at least one thread 12 for receiving the designated mother 23. The clamping plate 20 further has in the region of the bore 21 a countersunk hole 24 which serves to receive the nut 23. The size of the countersunk hole 24 and the size of the nut also correspond insofar as a radial distance is provided between the countersunk hole and the nut in order to have room for the attachment of a tool, for example a nut. After clamping the clamping plate 20 and the tie rod against the step an anchor plate 30 is attached to the clamping plate 20. The anchor plate lies flat on the clamping plate 20, since the height of the nut is less than the depth of the counterbore. The anchor plate 30 may for example be welded or screwed to the clamping plate. The anchor plate 30 is cast in the component, for example, if it is a concrete wall, or pegged to the wall.

Wie bereits an anderer Stelle erläutert ist auch denkbar, eine solche Treppenstufe an einer Spindel zu befestigen. Die Treppenstufe ist hierbei dann auf ihrer der Spindel zugewandten Stirnseite entsprechend dem Radius der Spindel gewölbt ausgebildet, was in gleicher Weise auch für die Spannplatte und die Ankerplatte gilt. Die Verbindung zwischen der Ankerplatte und der Spindel kann hierbei durch Schrauben oder auch durch eine Schweißverbindung erfolgen.As already explained elsewhere is also conceivable to attach such a step on a spindle. The step is in this case then curved on its end facing the spindle corresponding to the radius of the spindle formed, which applies in the same way for the clamping plate and the anchor plate. The connection between the anchor plate and the spindle can be done by screws or by a welded connection.
