Definitions

  • the invention relates to a staircase with a plurality of steps, in which each step is firmly connected at least at one side end to the subsequent step via two vertical supports and in which the bottom and top steps (22, 12) are on a ceiling (26, 24), a bar or the like.

Abstract

PCT No. PCT/EP90/00321 Sec. 371 Date Oct. 26, 1990 Sec. 102(e) Date Oct. 26, 1990 PCT Filed Feb. 26, 1990 PCT Pub. No. WO90/10129 PCT Pub. Date Sep. 7, 1990.The invention concerns a flight of stairs with a multiple of steps-where each step is firmly connected at least at one lateral end with the subsequent step by two vertical members, and where the bottom and top steps (22, 12) are resting on an intermediate floor (26, 24), a landing beam or a similar member, and where at least one lateral end of each step (12 to 22) is arranged within a square support-consisting of two horizontal and two vertical members (40, 42; 44, 46) which, together, form a stair stringer-in such a manner that each step is supported by its assigned horizontal member beneath it, and that each horizontal member (40, 42) is extended beyond a vertical member (44, 46), so that the extension (32) of the upper horizontal member (40) forms the lower horizontal member of the next step (12) above, while the extension (48) of the lower horizontal member (42) forms the upper horizontal member of the next step (16) beneath it, and where-at least on one side-a vertical member can be replaced by a spacer (206, 208, 306) or by the actual step (124, 128, 130) which, in this instance, must-at least on that side-be of the same thickness as a step height.

Description

Die Erfindung betrifft eine Treppe mit einer Vielzahl von Stufen, bei der jede Stufe an mindestens einem seitlichen Ende mit der nachfolgenden Stufe über zwei Vertikalträger fest verbunden ist und bei der die unterste und die oberste Stufe (22, 12) auf einer Decke (26, 24), einem Balken oder dergleichen aufliegen.The invention relates to a staircase with a plurality of steps, in which each step is firmly connected at least at one side end to the subsequent step via two vertical supports and in which the bottom and top steps (22, 12) are on a ceiling (26, 24), a bar or the like.

Es ist eine Vielzahl von Bauformen von Treppen bekannt. Eine Treppe kann in einem Stück vor Ort aus Beton gefertigt werden. Zur Verkleidung der Stufen werden dann Tritt- und Setzstufen aus einem gewünschten Material angeordnet. Ferner ist es bekannt, Geschoßdecken mittels vorgefertigten Balken zu verbinden, die nebeneinander angeordnet eine Treppe geben. Ferner ist es bekannt, beispielsweise Stufen einer Wendeltreppe an einem Ende in einer Wand zu verankern und die anderen Enden der Stufen übereinander anzuordnen, so daß diese Enden sich gegenseitig abstützen. Diese bekannten Treppen sind relativ aufwendig in der Herstellung und Sonderwünsche und Abweichungen von Normungen sind nur mit relativ großem Aufwand ausführbar.A variety of designs of stairs are known. A staircase can be made in one piece from concrete on site. Treads and risers made of a desired material are then arranged to cover the steps. Furthermore, it is known to connect storey ceilings by means of prefabricated beams which, when arranged side by side, provide a staircase. It is also known, for example, to anchor steps of a spiral staircase at one end in a wall and to arrange the other ends of the steps one above the other so that these ends support one another. These known stairs are relatively complex to manufacture and special requests and deviations from standards can only be carried out with relatively great effort.

Die DE-OS 19 63 909 beschreibt eine Wendeltreppe mit vorspringendem Antritt und einer Vielzahl von Stufen, bei der jede Stufe an mindestens einem seitlichen Ende mit der nachfolgenden Stufe über zwei parallele Vertikalträger fest verbunden ist, wobei Kräfte, die in horizontaler Richtung weitergeleitet werden müssen, unmittelbar in der als Horizontalträger wirkenden Trittstufe selbst übertragen werden. Das DE-Gbm 1943606 zeigt einen quaderförmigen Druckkörper, der sich zwischen zwei Stufen befindet, wobei Druckkörper und Stufen durch einen Vertikalanker zusammengehalten werden. Auch hier werden die in horizontaler Richtung weiterzuleitenden Kräfte unmittelbar in der Trittstufe selbst übertragen.DE-OS 19 63 909 describes a spiral staircase with a protruding approach and a plurality of steps, in which each step is firmly connected to the subsequent step via at least one lateral end with two parallel vertical supports, forces which have to be transmitted in the horizontal direction , are transmitted directly in the step which acts as a horizontal beam itself. DE-Gbm 1943606 shows a cuboid pressure body, which is located between two stages, the pressure body and stages being held together by a vertical anchor. Here, too, the forces to be transmitted in the horizontal direction are transmitted directly in the step itself.

Der Erfindung liegt die Aufgabe zugrunde, eine Treppe zu schaffen, die mit einfachen Mitteln hergestellt werden kann und bei der eine Anpassung an besondere Gegebenheiten leicht möglich ist.The invention has for its object to provide a staircase that can be manufactured with simple means and in which an adaptation to special circumstances is easily possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an mindestens dem einen seitlichen Ende jeder Stufe ein Trägerviereck aus zwei Horizontal- und den zwei Vertikalträgern, die zusammen eine Treppenwange bilden, angeordnet ist, daß jede Stufe sich auf den ihr zugeordneten, unteren Horizontalträger abstützt, daß jeder Horizontalträger über einen Vertikalträger hinaus berlängert ist und daß die Verlängerung des oberen Horizontalträgers den unteren Horizontalträger der benachbarten darüberliegenden Stufe und die Verlängerung des unteren Horizontalträgers den oberen Horizontalträger der benachbarten darunterliegenden Stufe bildet, wobei auf zumindest einer Seite zumindest ein Vertikalträger auch durch einen Abstandshalter oder durch die Treppenstufe selbst ersetzt sein kann, die in diesem Fall an wenigestens dieser Seite die Dicke einer Stufenhöhe hat.This object is achieved in that at least at one side end of each step a square of two horizontal and the two vertical beams, which together form a stair stringer, is arranged in that each step is supported on the associated lower horizontal beam that each horizontal beam is elongated beyond a vertical beam and that the extension of the upper horizontal beam forms the lower horizontal beam of the adjacent step above and the extension of the lower horizontal beam forms the upper horizontal beam of the adjacent step below, at least one vertical beam on at least one side by a spacer or can be replaced by the stair step itself, which in this case has the thickness of a step height on at least this side.

Mit den erfindunsgemäßen Elementen ist es möglich, eine Treppe vor Ort aus Einzelelementen zusammenzusetzen, die dann an dem vorgesehenen Platz zwischen zwei Geschoßdecken angeordnet werden kann. Anpassungen an die Gegebenheiten, d.h. Biegungen, Vetsetzungen oder dergl. können durch geeignete Wahl der Längen der Hotizontalträger ausgebildet werden.With the elements according to the invention, it is possible to assemble a staircase on site from individual elements, which can then be arranged in the space provided between two floor ceilings. Adjustments to the circumstances, i.e. Bends, displacements or the like can be formed by a suitable choice of the lengths of the horizontal beams.

Vorzugsweise sind an beiden Stufenenden Trägervievecke angeordnet. Die Stufen weisen dann keinerlei Verbindung zu einer Wand in einem Haus auf.Carrier corners are preferably arranged at both step ends. The steps then have no connection to a wall in a house.

Gemäß einer weiteren bevorzugten Ausführungsform ist ein Ende wenigstens einiger der Stufen in einer Wand verankert. Damit wird eine teilweise freitragende Treppe geschaffen. Es ist möglich, ein Ende jeder Stufe in einer Wand zu verankern, während das gegenüberliegende Ende frei ist, oder es können je nach örtlichen Gegebenheiten nur einige der Stufe in der Wand verankert sein, während die anderen Stufen an beiden Enden über Trägervierecke miteinander verbunden sind.According to a further preferred embodiment, one end of at least some of the steps is anchored in a wall. This creates a partially self-supporting staircase. It is possible to anchor one end of each step in a wall while the opposite end is free, or depending on local conditions, only some of the step may be anchored in the wall, while the other steps are connected at both ends via square beams .

Gemäß einer bevorzugten Ausführungsform werden die vorderen Vertikalträger jedes Trägervierecks von senkrechten Geländerstreben gebildet. Damit wird eine Kombination von Geländer und Halterungen für die Stufen erreicht, so daß sich der erforderliche Aufwand für die Anordnung der Stufen und die Befestigung des Geländers verringert. Wenn die Stufen beispielsweise um halbe Stufenbreite in Horizontalrichtung zueinander versetzt sind, können sämtliche Vertikalträger von senkrechten Geländerstreben gebildet werden, wobei die Geländerstreben dann durch die Stufen hindurch verlaufen, um bei einer Stufe einen vorderen und bei der nächsten (Fig. 2) oder übernächsten (Fig. 1) darunterliegenden Stufe einen hinteren Vertikalträger zu bilden.According to a preferred embodiment, the front vertical girders of each carrier rectangle are formed by vertical railing struts. A combination of railings and brackets for the steps is thus achieved, so that the effort required for the arrangement of the steps and the fastening of the railing is reduced. If, for example, the steps are offset by half a step width in the horizontal direction from one another, all vertical supports can be formed by vertical railing struts, the railing struts then running through the steps in order to have a front step in one step and the next step (FIG. 2) or the next ( Fig. 1) underlying stage to form a rear vertical beam.

In Weiterbildung der Erfindung kann mindestens eine der senkrechten Geländerstreben als Zugstab ausgebildet und an einer Decke, einem Balken oder dergl. angehängt sein. Dies ist insbesondere vorteilhaft bei seht langen Treppen, so daß mit Hilfe eines derartigen Zugstabes eine Abhängung der Treppe zwischen den Endauflagerungen ausgebildet werden kann.In a further development of the invention, at least one of the vertical railing struts can be designed as a tension rod and attached to a ceiling, a beam or the like. This is particularly advantageous for very long stairs, so that a suspension of the stairs between the end supports can be formed with the aid of such a tension rod.

Die Stufen können um Stufentiefe oder weniger horizontal zueinander versetzt sein. Wenn die Stufen um etwas mehr als eine Stufenbreite in Horizontalrichtung zueinander versetzt sind, verläuft der vordere Vertikalträger einer Stufe fluchtend mit dem hinteren Vertikalträger der benachbarten, darunter angeordneten Stufe. Auch bei dieser Anordnung kann eine Vereinfachung der Bauelemente erreicht werden.The steps can be offset from each other by step depth or less. If the steps are offset from each other by a little more than a step width in the horizontal direction, the front vertical support of one step runs flush with the rear vertical support of the adjacent step located below. With this arrangement, too, the components can be simplified.

Die Elemente jedes Trägervierecks bestehen vorzugsweise aus Metall, Kunststoff, Holz, Beton oder Verbundwerkstoffen, und sie können stangenförmig, rohrförmig oder im Querschnitt rechteckig, rund, oval, flach oder dergl. ausgebildet sein.The elements of each support rectangle are preferably made of metal, plastic, wood, concrete or composite materials, and they can be rod-shaped, tubular or rectangular in cross-section, round, oval, flat or the like.

Gemäß bevorzugten Ausführungsformen können auf den Stufen Tritt- und/oder Setzstufen angeordnet sein.According to preferred embodiments, steps and / or risers can be arranged on the steps.

Figur 1 zeigt eine Treppe 10 bestehend aus Stufen 12, 14, 16, 18, 20 und 22. Die Stufe 12 ist die oberste Stufe, die sich auf einer Geschoßdecke 24 abstützt, während die Stufe 22 die unterste Stufe bildet, die auf einem Boden 26 aufsitzt. Jede Stufe 12 bis 22 ist mit einem Ende an einer Wand 28 verankert, während an dem gegenüberliegenden freien Ende jeder Stufe ein Trägerviereck angeordnet ist. Das Trägerviereck der Stufe 12 besteht aus einem oberen Horizontalträger 30, einem unteren Horizontalträger 32, einem hinteren Vertikalträger 34 sowie einem vorderen Vertikalträger 36. Die Horizontalträger 30 und 32 sind mit den Vertikalträgern 34 und 36 verschraubt oder über eine andere Befestigungsart starr miteinander verbunden. Der obere Horizontalträger 30 erstreckt sich über den hinteren Vertikalträger 34 hinaus in einer Verlängerung 38. Diese Verlängerung 38 liegt auf der Geschoßdecke 24 auf. Der untere Horizontalträger 32 erstreckt sich über den vorderen Vertikalträger 36 hinaus in eine Verlängerung 40. Diese Verlängerung 40 bildet gleichzeitig den oberen Horizontalträger der Stufe 14, die sich an die Stufe 12 anschließt. Die Verlängerung 40 bildet mit einem unteren Horizontalträger 42, einem hinteren Vertikalträger 44 und einem vorderen Vertikalträger 46 ein Trägerviereck für die Stufe 14. Der untere Horizontalträger 42 erstreckt sich dabei wiederum über den vorderen Vertikalträger 46 in eine Verlängerung 48, die den oberen Horizontalträger eines Trägervierecks für die Stufe 16 bildet. Es ist zu sehen, daß der Träger 32 zusammen mit der Verlängerung 40 sowohl Teil des Trägervierecks für die Stufe 12 als auch Teil des Trägervierecks für die Stufe 14 ist. Dieses Wechselspiel von unterem Horizontalträger und oberem Horizontalträger für eine benachbart darunter anliegende Stufe setzt sich fort bis zur Stufe 22. An der unteren Stufe 22 ist ein Trägerviereck bestehend aus einem oberen Horizontalträger 50, einem unteren Horizontalträger 52, einem hinteren Vertikalträger 54 und einem vordeten Vertikalträger 56 angeordnet. Über den unteren Hotizontalträger 52 stützt sich die Stufe 22 und damit die gesamte Treppe auf dem Boden 26 ab. Der obere Horizontalträger 50 bildet dabei eine Verlängerung des unteren Horizontalträgers 58 der darüber angeordneten Stufe 20.Figure 1 shows a staircase 10 consisting of steps 12, 14, 16, 18, 20 and 22. The step 12 is the top step, which is supported on a floor 24, while the step 22 forms the bottom step, which is on a floor 26 sits on. Each step 12 to 22 is anchored at one end to a wall 28, while a support rectangle is arranged at the opposite free end of each step. The support square of stage 12 consists of an upper horizontal support 30, a lower horizontal support 32, a rear vertical support 34 and a front vertical support 36. The horizontal supports 30 and 32 are screwed to the vertical supports 34 and 36 or rigidly connected to one another by another type of fastening. The upper horizontal beam 30 extends beyond the rear vertical beam 34 in an extension 38. This extension 38 lies on the floor ceiling 24. The lower horizontal beam 32 extends beyond the front vertical beam 36 into an extension 40. This extension 40 also forms the upper horizontal beam of step 14, which adjoins step 12. The extension 40 forms, with a lower horizontal support 42, a rear vertical support 44 and a front vertical support 46, a support rectangle for the step 14. The lower horizontal support 42 in turn extends over the front vertical support 46 into an extension 48 which is the upper horizontal support of a support rectangle forms for level 16. It can be seen that the carrier 32 together with the extension 40 is both part of the square for stage 12 and part of the square for stage 14. This interplay of the lower horizontal beam and the upper horizontal beam for an adjacent adjacent level continues up to level 22. At the lower level 22 there is a square support consisting of an upper horizontal beam 50, a lower horizontal beam 52, a rear vertical beam 54 and a front vertical beam 56 arranged. The step 22 and thus the entire staircase are supported on the floor 26 via the lower horizontal support 52. The upper horizontal beam 50 forms an extension of the lower horizontal beam 58 of the step 20 arranged above it.

Wie aus Figur 1 zu ersehen ist, sind senkrechte Geländerstreben 62 durch Horizontalträger der Trägervierecke der Stufen 20 und 16 geführt. Dadurch ergibt sich eine sichere Befestigung, und gleichzeitig wird die Stabilität der Trägervierecke der Stufen 20 und 16 verbessert.As can be seen from FIG. 1, vertical railing struts 62 are guided through horizontal girders of the square brackets of steps 20 and 16. This results in a secure attachment, and at the same time the stability of the square brackets of steps 20 and 16 is improved.

Figur 2 zeigt eine Treppe 70 aus einer Vielzahl von Stufen 72, einer obersten Stufe 74 und einer untersten Stufe 76. An jeder Stufe 72 und 74 und 76 ist an einer Seite ein Trägerviereck, bestehend aus Horizontalträgern und Vertikalträgern, angeordnet, während die anderen Enden der Stufen in einer Wand verankert sind. Während bei der Ausführungsform nach Figur 1 die Stufen 12 bis 22 etwa um Stufentiefe zueinander versetzt sind, so daß der vordere Vertikalträger einer Stufe mit dem hinteren Vertikalträger einer darunterliegenden Stufe fluchtet, sind die Stufen bei der Ausführungsform nach Figur 2 um etwa halbe Stufentiefe zueinander versetzt, so daß der vordere Vertikalträger etwa über dem hinteren Vertikalträger einer Stufe liegt, die die übernächste Stufe zu der erstgenannten bildet. Ferner bilden in Abweichung zu der Ausführungsform nach Figur 1 senkrechte Geländerstreben 78 die vorderen Vertikalträger jedes Trägervierecks. Die Vertikalstreben 78 bilden zusammen mit einem Handlauf 80 ein Treppengeländer. Eine Vertikalstrebe 82 des Geländers ist an der Geschoßdecke 84 angehängt, an welcher die oberste Stufe 74 befestigt ist. Die Vertikalstrebe 82 dient damit gleichzeitig als Zugstab für die Treppe 70, so daß die Treppe neben der Aufhängung über die Stufe 74 unter Abstützung über die Stufe 76 eine Aufhängung aufweist, wodurch beispielsweise ein Schwingen der relativ lang ausgeführten Treppe bei der Begehung verhindert wird.Figure 2 shows a staircase 70 consisting of a plurality of steps 72, an uppermost step 74 and a lowermost step 76. At each step 72 and 74 and 76, a support rectangle, consisting of horizontal beams and vertical beams, is arranged on one side, while the other ends the steps are anchored in a wall. While the steps 12 to 22 in the embodiment according to FIG. 1 are offset from one another by approximately a step depth, so that the front vertical support of one step is aligned with the rear vertical support of an underlying step, the steps in the embodiment according to FIG. 2 are offset by approximately half a step depth , so that the front vertical support lies approximately above the rear vertical support of a step which forms the next but one step to the former. Furthermore, in deviation from the embodiment according to FIG. 1, vertical railing struts 78 form the front vertical supports of each support rectangle. The vertical struts 78 together with a handrail 80 form a banister. A vertical strut 82 of the railing is attached to the floor ceiling 84 to which the top step 74 is attached. The vertical strut 82 thus also serves as a tension rod for the stairs 70, so that the stairs have a suspension in addition to the suspension via the step 74 with support from the step 76, which prevents, for example, swinging of the relatively long stairs during the walk.

Figur 3 zeigt eine Treppe 90 mit Treppenstufen 92, die an beiden Enden mit Trägervierecken 94, 96 versehen sind, so daß an beiden Seiten der Treppe durchgehende Treppenwangen gebildet werden. Die Stufen sind um etwas mehr als Stufenbreite in Horizontalrichtung zueinander versetzt, so daß der vordere Vertikalträger 98 einer Stufe mit dem hinteren Vertikalträger 100 einer darunter angeordneten Stufe fluchtet.Figure 3 shows a staircase 90 with steps 92, which are provided at both ends with square brackets 94, 96, so that continuous stair strings are formed on both sides of the stairs. The steps are offset from each other by a little more than step width in the horizontal direction, so that the front vertical support 98 of one step is aligned with the rear vertical support 100 of a step arranged below.

Figur 4 zeigt eine Treppe 100, deren unterer Bereich gegenüber dem oberen Bereich verdreht ist. Die untere Stufe 102, die sich auf einem Boden 104 abstützt, ruht auf Trägern 106, 108 und besteht aus einer Vielzahl Stufenelementen. Darüber angeordnet ist eine Stufe 110, deren Vorderfläche 112 unter einem spitzen Winkel zur Vorderfläche 114 der unteren Stufe 102 verläuft. Zwischen den Stufen 110 und 102 ist ein Horizontalträger 116 und ein Horizontalträger 118 angeordnet. Der Horizontalträger 116 ist über einen Vertikalträger 120 mit einem langen Horizontalträger 122 verbunden, der gleichzeitig den unteren Horizontalträger einer Seite einer darüber angeordneten Stufe 124 bildet. Der obere Horizontalträger 126 der Stufe 124 bildet in Verlängerung den unteren Horizontalträger einer Stufe 128, die zusammen mit nachfolgenden Stufen 130, 132 wiederum gerade ausgerichtet ist. Die Verbindung der Horizontalträger 126 und 122 sowie mit dem oberen Horizontalträger 134 der Stufe 128 erfolgt über Vertikalträger 136 bzw. 138. Die anderen Enden der Stufen 110, 126, 128, 130 und 134 sind über Trägervierecke miteinander verbunden, die wie bei den Ausführungsformen nach den Figuren 1 bis 3 ausgebildet sind. Aus Figur 4 ist zu ersehen, daß die in der Zeichnung rechten Enden der Stufen 110, 124 und 128 fluchtend übereinander liegen und keinen Versatz aufweisen, während die Stufen 128, 130 und 132 regelmäßig zueinander versetzt sind.FIG. 4 shows a staircase 100, the lower area of which is twisted in relation to the upper area. The lower step 102, which is supported on a floor 104, rests on supports 106, 108 and consists of a plurality of step elements. Arranged above this is a step 110, the front surface 112 of which extends at an acute angle to the front surface 114 of the lower step 102. A horizontal support 116 and a horizontal support 118 are arranged between the steps 110 and 102. The horizontal support 116 is connected via a vertical support 120 to a long horizontal support 122, which at the same time forms the lower horizontal support on one side of a step 124 arranged above it. The upper horizontal support 126 of the step 124 forms the lower horizontal support of a step 128 which, together with the subsequent steps 130, 132, is in turn aligned. The connection of the horizontal beams 126 and 122 as well as with the upper horizontal beam 134 of the step 128 takes place via vertical beams 136 and 138, respectively. The other ends of the steps 110, 126, 128, 130 and 134 are connected to one another via beam rectangles which, as in the embodiments according to Figures 1 to 3 are formed. It can be seen from FIG. 4 that the ends of steps 110, 124 and 128 on the right in the drawing are aligned one above the other and have no offset, while steps 128, 130 and 132 are regularly offset from one another.

Die Figuren 5 bis 7 zeigen Einzeldarstellungen von Trägervierecken. Bei dem Ausführungsbeispiel nach Figur 5 sind beispielsweise in Form von Viereckrohren ausgebildete Horizontalträger 190 und 192 eines Trägervierecks 194 über stangenförmig ausgebildete Vertikalträger 196 und 198 verbunden.Figures 5 to 7 show individual representations of square beams. In the exemplary embodiment according to FIG. 5, horizontal supports 190 and 192 of a support rectangle 194, for example in the form of square tubes, are connected via vertical supports 196 and 198 in the form of rods.

Figur 6 zeigt ein Trägerviereck 200, bestehend aus im Querschnitt rechteckigen Horizontalträgern 202, 204, die über geschmiedete Vertikalträger 206 und 208 miteinander verbunden sind. Die Vertikalträger 206 und 208 können in der gezeigten Form auch als Abstandsstücke betrachtet werden.FIG. 6 shows a carrier rectangle 200, consisting of horizontal carriers 202, 204 which are rectangular in cross section and which are connected to one another via forged vertical carriers 206 and 208. The vertical supports 206 and 208 can also be considered as spacers in the form shown.

Bei dem in Figur 7 gezeigten Trägerviereck 210 werden sowohl die Horizontalgräger 212 und 214 als auch die Vertikalträger 216 und 218 aus im Querschnitt rechteckigen oder quadratischen Stangen oder Viereckrohren gebildet. Die Verschraubungen der Vertikalträger sind bei der gezeigten Form abgedeckt.In the support rectangle 210 shown in FIG. 7, both the horizontal supports 212 and 214 and the vertical supports 216 and 218 are formed from rods or square tubes which are rectangular or square in cross section. The screw connections of the vertical beams are covered in the form shown.

Während bei den Ausführungsformen nach den Figuren 3 und 4 die Stufen aus kompakten Balken ohne Setz- und Trittstufen gebildet werden, sind beiden Ausführungsformen nach den Figuren 1 und 2 auf den Stufen Trittstufen 220 bzw. 222 (Fig. 2) angeordnet. Ebenfalls könnten an den Stufen Setzstufen aus einem gewünschen Material und einem gewünschten Dekor vorgesehen sein.While in the embodiments according to FIGS. 3 and 4 the steps are formed from compact beams without risers and steps, both embodiments according to FIGS. 1 and 2 are arranged on steps 220 and 222 (FIG. 2). Risers could also be provided on the steps from a desired material and a desired decor.

Figur 8 zeigt die Krümmung oder Abwinkelung von Horizontalträgern um eine vertikale Achse zur Anpassung an die Form einer Wand, z.B. bei Wendeltreppen. Figur 9 zeigt die Biegung des Horizontalträgers um ca. 90°, wobei nach der Biegung der Horizontalträger jeweils den vorhergehenden und darauffolgenden Vertikalträger bildet, oder umgekehrt die Biegung des Vertikalträgers, der dann den darunter- oder darüberliegenden Horizontalträger bildet. Die Kreuzungspunkte können verschraubt oder verschweißt werden. Dies stellt eine sehr elegante und auch sehr stabile Treppenform dar.FIG. 8 shows the curvature or angling of horizontal beams around a vertical axis to adapt to the shape of a wall, for example in the case of spiral stairs. FIG. 9 shows the bend of the horizontal beam by approx. 90 °, with the horizontal beam forming the preceding and following vertical beam after the bend, or vice versa, the bend of the vertical beam, which then forms the forms horizontal or underlying horizontal beams. The crossing points can be screwed or welded. This is a very elegant and also very stable staircase shape.

Das in Figur 10 gezeigte Abstandsstück erfordert nur einen Vertikalträger, der natürlich auch als Geländerstab durchgezogen sein kann.The spacer shown in FIG. 10 only requires a vertical support, which of course can also be pulled through as a railing rod.

Die in Figur 11 gezeigte Trägerform aus einem I-Träger eignet sich insbesondere für vorübergehend benötigte Treppen, z.B. Bautreppen, da sie leicht abgebaut und wieder neu zusammengesetzt werden können. Als Treppenstufen kommen hier bei Verwendung auf Baustellen vor allem Gitterroste in Frage, die sehr rutschfest sind.The support form shown in Figure 11 made of an I-beam is particularly suitable for temporarily required stairs, e.g. Construction stairs, as they can be easily dismantled and reassembled. Gratings that are very non-slip are particularly suitable as stair treads when used on construction sites.

Selbstverständlich kann der untere Flansch um eine weitere Treppenbreite nach vorne unten verlängert sein, um direkt den darunterliegenden Horizontalträger zu bilden oder ein weiteres I-Trägerstück, das identisch zum abgebildeten gemäß Fig. 11 ist, kann daruntergesetzt werden, wobei dann die Schraublöcher 307 des darunterliegenden Stücks mit den Schraublöchern 308 des darüberliegenden Stücks verschraubt werden (ebenso die vorderen Schraublöcher 309 des obenliegenden Trägerteils mit den Schraublöchern 310 des darunterliegenden Trägerteils.Of course, the lower flange can be extended by a further stair width to the front to form the underlying horizontal beam directly, or another I-beam piece that is identical to the one shown in FIG. 11 can be placed underneath, with the screw holes 307 of the one below Are screwed to the screw holes 308 of the overlying piece (as are the front screw holes 309 of the upper support part with the screw holes 310 of the underlying support part.
