Abstract
Description
Die Erfindung betrifft eine selbsttragende Elementtreppe, vorzugsweise eingesetzt als Außentreppe, wie sie sowohl als Begehungstreppe in Industrieanlagen als auch als Brand-Fluchttreppen an Hotels oder sonstigen Großgebäuden, sowie als Außentreppen im Wohnungsbau Verwendung findet.The invention relates to a self-supporting elementary staircase, preferably used as an external staircase, as it is used both as an inspection staircase in industrial plants and as a fire escape staircase in hotels or other large buildings, and as an external staircase in residential construction.
Derartige Treppen mußten bisher stets auf jeden Anwendungsfall individuell abgestimmt werden. Ebenso die behördlich vorgeschriebene Verkehrslast von 5 KN/m² lassen hier normale Standardtreppen scheitern, so daß der Bau einer solchen Treppe stets mit hohen Kosten verbunden war.Up to now, such stairs have always had to be individually tailored to each application. Likewise, the officially prescribed traffic load of 5 KN / m² make normal standard stairs fail, so that the construction of such stairs was always associated with high costs.
Auch die bisher bekannten Spindeltreppen, bei der sämtliche Stufen an einem zentralen Rohr befestigt sind, lassen sich nur bedingt einsetzen, da bei der Überwindung größerer Höhen die Statik hier an nicht überwindbare Grenzen stößt. Die Treppe der deutschen Patentanmeldung P 3637807 vermeidet zwar die genannten Nachteile, ist jedoch in ihrer Bauart noch zu materialintensiv.Even the previously known spiral staircases, in which all the steps are attached to a central tube, can only be used to a limited extent, since the statics reach insurmountable limits when overcoming greater heights. The staircase of the German patent application P 3637807 avoids the disadvantages mentioned, but its construction is still too material-intensive.
Aufgabe der Erfindung ist es, eine Treppe für oben genannte Einsatzfälle zu schaffen, die wirtschaftlich herzustellen und zu montieren ist, gering im Materialverbrauch, sowie praktisch für jeden beliebigen Treppenlauf ohne Sonderkonstruktion zu verwenden ist.The object of the invention is to provide a staircase for the above-mentioned applications, which is economical to manufacture and assemble, low in material consumption and can be used practically for any staircase run without a special construction.
Erfindungsgemäß wird die Aufgabe gelöst durch eine Stahlrohrkonstruktion, welche aus U-förmigen Verbindungsbügeln, an den oberen Enden der Verbindungsbügel aufgesetzten Handlaufteilen und an den unteren Enden der Verbindungsbügel durch Klemmverbindungen eingesetzte Trittstufen besteht, wobei die Verbindungsbügel an den oberen Enden durch die Handlaufteile und im unteren Beseich durch die Trittstufen verbunden sind.According to the invention the object is achieved by a tubular steel construction which consists of U-shaped connecting brackets, handrail parts attached to the upper ends of the connecting brackets and treads inserted at the lower ends of the connecting brackets by clamping connections, the connecting brackets at the upper ends by the handrail parts and in the lower Beich connected by the steps.
Weitere Merkmale der Erfindung bestehen darin, daß nur drei Elemente, Verbindungsbügel, Handlaufteil und Trittstufe, erforderlich sind, um eine komplette Treppe zu realisieren und daß mit fünf Serienteilen, Verbindungsbügel, Außenhandlaufteil, Innnhandlaufteil, Trittstufe für Radien, Trittstufe für Geradeauflauf, jede gewünschte Treppenlaufform herstellbar ist.Further features of the invention consist in the fact that only three elements, connecting bracket, handrail part and step are required to realize a complete staircase and that with five series parts, connecting bracket, outer handrail part, inner handrail part, step for radii, step for straight entry, any desired step shape can be produced.
Die Erfindung soll mit Hilfe der Zeichnung näher erläutert werden.The invention will be explained in more detail with the aid of the drawing.
Fig. 1 zeigt den typischen Treppenlauf einer Wendeltreppe. Für die Herstellung dieses Treppenlaufes genügen 4 Bauelemente: Stufe, Verbindungsbügel, Außen- und Innenhandlaufteil.Fig. 1 shows the typical flight of stairs of a spiral staircase. 4 components are sufficient to manufacture this stair run: step, connecting bracket, outer and inner handrail part.
Fig. 2 und 3 zeigen Treppenläufe, die alle Varianten enthalten. Neben dem schon vorhandenen Element der Wendeltreppe, welches für alle Radienteilabschnitte des Treppenlaufes verwendet wird, muß hier lediglich nur noch die Trittstufe für den Geradeauslauf eingesetzt werden, um die geraden Abschnitte der Treppenläufe damit abzudecken.2 and 3 show staircases that contain all variants. In addition to the already existing element of the spiral staircase, which is used for all radius sections of the stairway, only the step for the straight-ahead run has to be used to cover the straight sections of the staircase.
Fig. 4 zeigt die perspektivische Darstellung zweier zusammenzusetzender Stufenelemente.Fig. 4 shows the perspective view of two step elements to be assembled.
Fig. 5 zeigt die Trittstufe für Geradeauslauf und Fig. 6 die Trittstufe für Radien.Fig. 5 shows the step for straight running and Fig. 6 shows the step for radii.
Fig. 7 zeigt vergrößert die auf die oberen Enden der Verbindungsbügel aufgesteckten Handlaufteile, sowie deren Befestigung.Fig. 7 shows an enlarged view of the handrail parts attached to the upper ends of the connecting brackets, and their attachment.
Zentrales Bauelement der Treppe ist der U-förmig gebogene Verbindungsbügel (1) aus Stahlrohr. Untereinander verbunden werden die Verbindungsbügel an den oberen Enden durch die Handlaufteile (2) und im unteren Bereich durch die Trittstufen (3). Die Handlaufteile (2) bestehen aus einem entsprechend der Treppenneigung gebogenen Stahlrohr mit einseitig quer angeschweißter Verbindungsmuffe (5). In diese Verbindungsmuffe wird von unten der Verbindungsbügel (1) und von oben das freie Ende des folgenden Handlaufteiles eingesteckt.The central component of the staircase is the U-shaped connecting bracket (1) made of tubular steel. The connecting brackets are connected to each other at the upper ends by the handrail parts (2) and in the lower area by the steps (3). The handrail parts (2) consist of a steel tube bent according to the stair inclination with a connecting sleeve (5) welded crosswise on one side. The connecting bracket (1) is inserted into this connecting sleeve from below and the free end of the following handrail part from above.
Entsprechendes konstruktionsseitig vorgesehenes axiales Spiel zwischen den eingesteckten Rohrenden berücksichtigt den bei der Treppenmontage notwendigen Tritthöhenausgleich. Gewindestifte (7) helfen bei der Justage und Spannstifte (8) geben der Verbindung die notwendige statische Belastungsfähigkeit. Dabei brauchen lediglich die bereits in der Verbindungsmuffe (5) vorhandenen Löcher mit der Handbohrmaschine durch das eingesteckte Rohrende durchgebohrt zu werden.Corresponding axial play provided by the construction between the inserted pipe ends takes into account the step height compensation necessary when installing the stairs. Setscrews (7) help with the adjustment and dowel pins (8) give the connection the necessary static load capacity. All that is required is to drill the holes already in the connecting sleeve (5) with the hand drill through the inserted pipe end.
Die Trittstufen (3) bestehen aus einem Flachstahlrahmen, der an allen vier Ecken als Rohrschelle ausgebildet ist. Diese Rohrschellen greifen in den unteren Bereich zweier Verbindungsbügelpaare und sorgen durch Anzug der 3 bzw. 4 Rohrschellenschrauben für eine besonders steife Verbindung. Als Trittstufe kommen je nach Treppenlaufform zwei Stufenformen zum Einsatz. Die Geradentrittstufe (Fig. 5) für die Geradeausführung des Treppenlaufes und die Radiusstufe (Fig. 6) für die Kurvenführung des Treppenlaufes. Die Rahmenkonstruktion der Trittstufen kann dabei durch Gitterrost, Lochblech, Tränenblech, Stein, Holz sowie durch Kunststoffbelägen ausgefüllt werden. Die Symmetrie der Radiusstufe macht ihre Verwendung sowohl für den Rechtsbogen als auch für den Linksbogen des Treppenlaufes möglich.The steps (3) consist of a flat steel frame, which is designed as a pipe clamp at all four corners. These pipe clamps reach into the lower area of two pairs of connecting brackets and ensure a particularly rigid connection by tightening the 3 or 4 pipe clamp screws. Depending on the shape of the staircase, two steps are used as the step. The straight step (Fig. 5) for the straight execution of the staircase and the radius step (Fig. 6) for the curve of the staircase. The frame construction of the steps can be filled with grating, perforated plate, teardrop plate, stone, wood and plastic coverings. The symmetry of the radius step makes it possible to use it for both the right-hand arch and the left-hand arch of the flight of stairs.
Ein am Handlaufteil (2) angeschweißtes Blech (6) dient als Aufnahme der Geländerstäbe (4), die im unteren Bereich an der Trittstufe befestigt sind. Diese Möglichkeit stellt nur eine von vielen dar. So sind auch komplette Auskleidungen durch Lochblech o.ä. denkbar.A sheet metal (6) welded to the handrail part (2) serves to accommodate the railing rods (4) which are fastened to the step in the lower area. This option is only one of many. Complete linings made of perforated sheet or similar are also possible. conceivable.
Durch die Einfachheit der wenigen Teile läßt sich die Treppe ohne Biege-Nacharbeit sehr schnell montieren. Spezielle Oberflächenbehandlungen der fertigen Stahlrohr- u. Trittstufenelemente können somit vor der Montage der Treppe erfolgen, da es sich dabei um absolut fertige Einzelteile handelt.Due to the simplicity of the few parts, the stairs can be assembled very quickly without reworking. Special surface treatments of the finished tubular steel u. Step elements can thus be made before the stairs are assembled, since they are completely finished individual parts.
Geringster Materialeinsatz und Transportgewicht, größtmögliche Stabilität und einfache Montage ohne Nacharbeit machen diese Treppe zu einem besonders wirtschaftlichen Produkt. Die einfache technische Formgebung, die Dominanz der gebogenen Stahlrohre verleihen der Treppe darüber hinaus auch ein ansprechendes Design.The minimal use of materials and transport weight, the greatest possible stability and simple assembly without reworking make this staircase a particularly economical product. The simple technical design and the dominance of the curved steel tubes also give the stairs an appealing design.
