Description

r e p p e r e p p e
Die vorliegende Erfindung betrifft eine Treppe für eine begeh- und/oder befahrbare Vorrichtung, insbesondere für eine Über- oder Unterbruckung, mit Stufen und Seitenholmen.The present invention relates to a staircase for a device that can be walked on and / or driven over, in particular for bridging over or under, with steps and side rails.
Aus der DE 196 25 819.7 AI ist eine begeh- und/oder befahrbare Vorrichtung beispielsweise zum Unterbrucken von sanierungsbedurftigen Brücken oder zum Überbrücken von Strassen bekannt, die einen begehbaren Steg aufweist, der über Querstreben mit Handlaufen verbunden ist. Dabei sollen der begehbare Steg und/oder die Querstreben und/oder die Handlaufe aus stranggepressten Aluminiumprofllen bestehen.DE 196 25 819.7 AI discloses a device that can be walked on and / or driven over, for example for bridging bridges in need of renovation or for bridging streets, which has a walkable web that is connected to handrails via cross struts. The walkable web and / or the cross struts and / or the handrail should consist of extruded aluminum profiles.
Das Wesentliche an dieser Erfindung ist, dass die gesamte Brücke inklusive Steg, Querstreben, Handlaufe und Verbmdungselemente aus Aluminiumprofllen hergestellt und baukastenartig zusammengesetzt wird. Da sich derartige Brücken in einer gewissen Hohe über beispielsweise einer Fahrbahn erstrecken, ist es notwendig, Treppen vorzusehen, mit denen diese Brücken erreicht werden können .The essence of this invention is that the entire bridge, including the bridge, cross struts, handrail and connecting elements, is made of aluminum profiles and assembled in a modular manner. Since such bridges extend to a certain height over, for example, a roadway, it is necessary to provide stairs with which these bridges can be reached.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Treppe zu entwickeln, die ebenfalls im Baukastenprinzip hergestellt werden kann, einfach und kostengünstig ist.The present invention has for its object to develop a staircase that can also be produced in a modular manner, is simple and inexpensive.
Zur Losung dieser Aufgabe fuhrt, dass die Stufen und/oder die Seitenholme aus Abschnitten von stranggepressten Aluminiumprofllen bestehen.The solution to this task is that the steps and / or the side rails consist of sections of extruded aluminum profiles.
Stranggepresste Aluminiumproflle haben den Vorteil, dass sie im Verhältnis zu beispielsweise Stahlprofllen wesentlich leichter sind. Ferner können durch das Strangpressen fast beliebig gewünschte Profile hergestellt und von diesen dann die benotigten Abschnitte abgeschnitten werden. Hierdurch wird die gesamte Herstellung der Treppe erleichtert und vor allem verbilligt.Extruded aluminum profiles have the advantage that they are considerably lighter than steel profiles, for example. Furthermore, almost any desired profiles can be produced by the extrusion and the required sections can then be cut off from them. This makes the entire manufacture of the stairs easier and, above all, cheaper.
Ferner ist es auch möglich, im Strangpressverfahren Aluminiumproflle so herzustellen, dass sie eine sehr hohe Steifigkeit aufweisen. Dies ist für die erfmdungsgemasse Treppe von erheblichem Vorteil.Furthermore, it is also possible to use the extrusion process to produce aluminum profiles so that they have a very high rigidity. This is of considerable advantage for the stairs according to the invention.
Bevorzugt soll die erfmdungsgemasse Treppe mit einer oben zur DE 196 25 819.7 AI beschriebenen Brücke Verwendung finden. Allerdings soll darauf nicht die Erfindung beschrankt sein, die erfmdungsgemasse Treppe kann auch bei anderen Bruckenkonstruktionen Anwendung finden.Preferably, the stairs according to the invention are to be used with a bridge described above for DE 196 25 819.7 AI. However, the invention is not intended to be limited to this; the stairs according to the invention can also be used in other bridge constructions.
Ein weiterer Teil der vorliegenden Erfindung bezieht sich vor allem auf die Ausgestaltung der Stufen. Erfmdungsgemass sollen diese Stufen über Profilabschnitte mit den Seitenholmen verbunden sein. Dabei sind vor allem zwei Profile vorgesehen, und zwar zum einen ein E hangeprofil und zum anderen ein Auflageprofil . Das Auflageprofil ist so ausgestaltet, dass es ein Ende einer unteren Stufe mit einem Anfang einer nachfolgenden Stufe verbindet. Ferner wird dieses Auflageprofil auf dem Seitenholm festgelegt, was beispielsweise durch entsprechende Nieten, Schrauben aber auch durch Schweissen geschehen konnte.Another part of the present invention relates primarily to the configuration of the stages. According to the invention, these stages are to have profile sections be connected to the side rails. There are mainly two profiles provided, namely an E hanging profile and the other a support profile. The support profile is designed in such a way that it connects an end of a lower step with a beginning of a subsequent step. Furthermore, this support profile is fixed on the side rail, which could be done, for example, by appropriate rivets, screws, but also by welding.
In einem bevorzugten Ausfuhrungsbeispiel weist das Auflageprofil zwei Schenkel auf, die miteinander einen stumpfen Winkel e schliessen . Wahrend der eine Schenkel von dem Seitenholm aufragt und etwa vertikal steht, liegt der andere Schenkel als Auflageschenkel dem Seitenholm an. Bevorzugt weist er dabei an seiner Anlageflache Rastrippen auf, die wiederum mit einer entsprechend gerippten Oberflache der Seitenholme zusammenwirkt, so dass der Auflageschenkel nicht abrutschen kann.In a preferred exemplary embodiment, the support profile has two legs which form an obtuse angle e with one another. While one leg protrudes from the side rail and is approximately vertical, the other leg lies as a support leg against the side rail. It preferably has latching ribs on its contact surface, which in turn cooperates with a correspondingly ribbed surface of the side rails, so that the support leg cannot slide off.
An seinem freien Ende besitzt der Auflageschenkel eine E hangenut für das oben erwähnte Emhangeprofil . Dabei soll bevorzugt die Emhangenut teilkreisformig gerundet sein, so dass eine entsprechend gerundete Kralle des Emhangeproflls in einem gewissen Bogen m dieser Emhangenut bewegt werden kann. Hierdurch wird eine unterschiedliche Steigung einer Treppe ausgeglichen, so dass die eigentliche Trittflache immer etwa waagerecht gehalten werden kann.At its free end, the support leg has an E hangenut for the above-mentioned Emhangeprofil. In this case, the groove of the mouth should preferably be rounded in the shape of a part circle, so that a correspondingly rounded claw of the eye profile can be moved in a certain arc in this groove of the mouth. This compensates for a different slope of a staircase so that the actual tread surface can always be kept approximately horizontal.
Auch für den etwa vertikal aufragenden Schenkel weist die vorliegende Erfindung eine Besonderheit auf. Dieser Schenkel besitzt zumindest zwei Einstecknuten, deren Ebenen m einem spitzen Winkel zueinander verlaufen. Je nach Wahl der Treppensteigung wird der Trittbogen n die eine oder die andere Nut eingesteckt, so dass eine unterschiedliche Steigung der Treppe ausgeglichen werden kann.The present invention also has a special feature for the approximately vertically projecting leg. This leg has at least two insertion grooves, the planes of which run at an acute angle to one another. Depending on the choice of stairs, the step n becomes one or the other the other groove is inserted so that a different slope of the stairs can be compensated.
Um nun das Baukastenprinzip zu vollenden, sollen auch die Profilabschnitte in einem bevorzugten Ausführungsbeispiel aus Abschnitten von strangepressten Aluminiumprofilen bestehen . In order to complete the modular principle, the profile sections in a preferred exemplary embodiment should also consist of sections of extruded aluminum profiles.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausfuhrungsbeispiele sowie anhand der Zeichnung; diese zeigt inFurther advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing; this shows in

Gemass Figur 1 weist eine Treppe T Stufen 1 auf, die auf Seitenholmen 2 festliegen, wobei im vorliegenden Ausfuhrungsbeispiel nur ein Seitenholm gezeigt ist.According to FIG. 1, a staircase T has steps 1 which are fixed on side rails 2, only one side rail being shown in the present exemplary embodiment.
Jeder Seitenholm besteht aus kastenförmigen Abschnitten 3, die bevorzugt von einem stranggepressten Aluminiumprofil abgeschnitten sind. Benachbarte Abschnitte 3.1 und 3.2 werden an einer Stoßstelle 4 miteinander verbunden, insbesondere miteinander verschweisst .Each side rail consists of box-shaped sections 3, which are preferably cut off from an extruded aluminum profile. Adjacent sections 3.1 and 3.2 are connected to one another at a joint 4, in particular welded to one another.
Endwartige Abschnitte 3.3 und 3.4 weisen ein Gelenk 5.1 und 5.2 auf, wobei die Treppe T über das Gelenk 5.1 gelenkig mit einer Planke verbunden ist, wie sie beispielsweise n der DE 196 25 819 AI gezeigt ist. Hierzu genügt es, wenn einander zugeordnete Scharnierproflle zahnartig ineinander greifen, und durch entsprechende Augen ein nicht naher gezeigter Querstab hindurchgesteckt ist.End-like sections 3.3 and 3.4 have a joint 5.1 and 5.2, the staircase T being articulated via the joint 5.1 to a plank, as is shown, for example, in DE 196 25 819 AI. It is sufficient for this if hinge profiles assigned to one another engage in a tooth-like manner and a crossbar (not shown) is inserted through corresponding eyes.
Auch das Gelenk 5.2 am unteren Ende der Treppe T geht eine gelenkige Verbindung mit einem nicht naher gezeigten Endstufenprofil ein, über welches sich die Treppe T gegen einen Untergrund od.dgl. abstutzt.The joint 5.2 at the lower end of the staircase T also has an articulated connection with one not shown in more detail Power stage profile, over which the stairs T or the like against an underground. trimmed.
Im vorliegenden Ausfuhrungsbeispiel setzt sich eine Stufe 1 aus einer Trittflache 6 und einem Trittbogen 7 zusammen. Die Trittflache 6 ist über ein Emhangeprofil 8 mit einem erf dungsgemassen Auflageprofil 9 gekoppelt, welches, wie in Figur 3 gezeigt, aus zwei Schenkeln 10 und 11 besteht, die einen stumpfen Winkel emschliessen . Der Auflageschenkel 11 liegt dem Seitenholm 2 direkt an, wobei er an einer Anlageflache 12 mit Rastrippen 13 versehen ist. Diese Rastrippen 13 wirken in Gebrauchslage mit Querrippen 14 auf den Seitenholmen 2 zusammen, so dass der Auflageschenkel 11 nicht abrutschen kann.In the present exemplary embodiment, a step 1 is composed of a step surface 6 and a step arch 7. The tread surface 6 is coupled via a receiving profile 8 to a support profile 9 according to the invention, which, as shown in FIG. 3, consists of two legs 10 and 11 which develop an obtuse angle. The support leg 11 lies directly against the side rail 2, wherein it is provided on a contact surface 12 with locking ribs 13. In the position of use, these locking ribs 13 interact with transverse ribs 14 on the side rails 2, so that the support leg 11 cannot slip off.
An seinem freien Ende besitzt der Auflageschenkel 11 eine Emhangenut 15, welche teilkreisformig gerundet ausgebildet ist. In diese Emhangenut 15 wird das Emhangeprofil 8 mit einer entsprechend gerundeten Kralle 16 eingesetzt, wobei die Kralle 16 m der Emhangenut 15 geringfügig drehen kann und so die Stufe 1 einer Steigung einer Treppe angepasst wird .At its free end, the support leg 11 has an reception groove 15 which is rounded in the shape of a part circle. In this channel groove 15, the channel profile 8 is inserted with a correspondingly rounded claw 16, the claw 16 m of the channel groove 15 being able to rotate slightly, and so step 1 is adapted to an incline of a staircase.
Von dem Auflageschenkel 11 ragt der andere Schenkel 10 m etwa vertikal auf und dient der Verbindung mit dem Trittbogen 7. Hierzu weist dieser Schenkel 10 zwei Einstecknuten 17 und 18 auf, die jeweils in einer Ebene Ex bzw. E2 verlaufen, die miteinander einen spitzen Winkel v emschliessen. In den Figuren 1 und 2 ist erkennbar, dass beim Einsetzen des Trittbogens 7 in die Emstecknut 17 die Treppe einen höheren Steilheitsgrad aufweist als beim Einstecken in die Emstecknut 18 gemass Figur 2.The other leg projects 10 m from the support leg 11 approximately vertically and is used for connection to the step arch 7. For this purpose, this leg 10 has two insertion grooves 17 and 18, each of which extends in a plane E x or E 2 , one with the other Close acute angle. It can be seen in FIGS. 1 and 2 that when the step arch 7 is inserted into the insertion groove 17, the stair has a higher degree of steepness than when it is inserted into the insertion groove 18 according to FIG. 2.
