Description
DEUTSCHESGERMAN
Die Erfindung betrifft eine Form zum Herstellen von wenigstens eine Wange aufweisenden Keilstufen für Wendeltreppen aus Beton, wobei die Formwände mittels Scharniere aneinander angelenkt sind.The invention relates to a mold for producing wedge steps having at least one cheek for spiral staircases made of concrete, the walls of the mold being linked to one another by means of hinges.
Bekannt ist eine aus zwei Formlangwänden und aus zwei Formkurzwänden bestehende Form zum Herstellen von wangenlosen, im Querschnitt rechteckigen Stufen für Wendeltreppen. Dabei ist jede Formwand mittels Gelenkbolzen an die benachbarte Formwand angeschlossen. Jede der beiden Formkurzwände bildet eine der beiden Stirnflächen des Formlings.A mold consisting of two long mold walls and two short mold walls is known for production of cheekless, rectangular cross-section steps for spiral staircases. Every wall form is here connected to the adjacent mold wall by means of hinge pins. Each of the two mold walls forms one of the two end faces of the molding.
Demgegenüber sind beim Erfindungsgegenstand die beiden Formlangwände in Art einer Schere durch ein Scharnier miteinander verbunden. Die Formlangwände tragen die Formkurzwände, so daß beim Entschalen und beim Schließen der Form diese Formkurzwände mit den Formlangwänden bewegt werden. Der Vorteil dieser Bauart besteht darin, daß die Form einfach gehandhabt werden kann. Von der Form lassen sich drei bzw. vier Stirnflächen des Formlings begrenzen, wovon zwei der Stirnflächen Außenstirnflächen und die dritte oder die dritte und die vierte Stirnfläche Innenstirnflächen der Wange bzw. der Wangen sind.In contrast, in the subject matter of the invention, the two long walls of the mold are in the form of scissors through a Hinge connected to each other. The long walls of the mold carry the short walls of the mold, so that when demoulding and when the mold is closed, these short mold walls are moved with the long mold walls. The advantage of this design is that the shape can be handled easily. Let go of the form three or four end faces of the molding limit, of which two of the end faces are outer end faces and the third or the third and the fourth end face inner end faces of the cheek or the Cheeks are.
In weiterer Ausgestaltung der Erfindung weisen die Formlängswände Leisten für Schrägstoßflächen der Keilstufe auf, so daß Formlinge in der Form fertig gebildet werden können, die beim Erstellen der Wendeltreppe Verzahnungen bekannter Art ergeben.In a further embodiment of the invention, the longitudinal walls of the mold have strips for inclined joint surfaces the wedge step on, so that moldings can be finished in the form that was used when creating the Spiral staircase teeth of a known type result.

Bild 4 einen Querschnitt einer Form mit dem Keilstufenformling zeigt;Figure 4 shows a cross-section of a mold with the wedge-step molding shows;
Bild 5 veranschaulicht die Form in der Draufsicht.Figure 5 illustrates the shape in plan view.
Die beiden Formlangwände I1 2 der Form sind in Art einer Schere durch ein Scharnier 4 miteinander verbunden, tragen die Formkurzwände 1 a, 1 b, 2 a, 2 b und weisen Leisten Ic, 2c für Schrägstoßflächen 5, 6 der Keilstufe (Formling 3) auf.The two long mold walls I 1 2 of the mold are connected to one another by a hinge 4 in the manner of a pair of scissors, carry the short mold walls 1 a, 1 b, 2 a, 2 b and have strips Ic, 2c for inclined joint surfaces 5, 6 of the wedge step (molding 3 ) on.
Beim Herstellen des Formlings 3 liegt dieser mit der Fläche 4, die die Begehfläche der in die Wendeltreppe eingebauten Keilstufe darstellt, auf dem Erdboden (Betonfußboden) auf, so daß sich seine Wangen 3 a, 3 b vom Erdboden bis zur oberen Schrägstoßfläche 5 erstrecken. Die Formkurzwand 1 α kann beim Entschalen des Formlings 3 mittels des Scharniers 7 in Richtung C von diesem weggeklappt werden.When the molding 3 is produced, it rests on the ground (concrete floor) with the surface 4, which represents the walking surface of the wedge step built into the spiral staircase, so that its cheeks 3 a, 3 b extend from the ground to the upper inclined joint surface 5. The mold short wall 1 α can be folded away from the molding 3 by means of the hinge 7 in the direction C when the molding is removed.

Die Formkurzwände 1 a, Ib, 2 a, 26 können verstellbar sein, so daß ihr Abstand vom Scharnier 4 veränderbar ist.The short mold walls 1 a, 1 b, 2 a, 26 can be adjustable so that their distance from the hinge 4 can be changed.
Die Wange 3 α kann langer sein, als dies in den Bildern gezeigt ist, doch ändert der dadurch bedingte Umbau der Form den Erfindungsgegenstand nicht. Eine in dieser Art verlängerte Außennwange, die bei einem Treppenhaus mit einer äußeren und mit einer inneren Treppenhauswand Teil der äußeren Treppenhauswand ist, bietet beim Aufmauern des Treppenhauses der jeweils obersten Keilstufe den Vorteil der besonders großen Kippsicherheit.The cheek 3 α can be longer than shown in the pictures, but the resulting reconstruction of the shape does not change the subject matter of the invention. An outer cheek extended in this way, which is part of the outer staircase wall in a staircase with an outer and an inner staircase wall, offers the advantage of particularly high tipping safety when building up the staircase of the respective uppermost wedge step.
