Description
Auswechselbare Formeinlage zur Herstellung von profilierten Treppenstufen Bei der fabrikmäßigenHerstellungprofilierter gerundeter Treppenstufen wird das gebogene Profil entweder durch entsprechende Holz- oder Gypseinlagen der Treppenstufenform erzeugt. Durch die in der Abbildung dargestellte, den Gegenstand der Erfindung bildende Formeinlage wird die Herstellung dieser Stufen sehr vereinfacht. Diese Formeinlage besteht aus einem elastischen Gummistreifen nebst anliegendem elastischem Stahlblechschutzstreifen. Es lassen sich mit dieser elastischen Profileinlage Stufen in jeder Biegung und Rundung herstellen. Es sind zwar bereits Profileinlagen aus Blech für Treppenstufenformen bekannt, bei denen neben den starren Eisenblechstreifen elastische Verwendung finden, jedoch ist das aus diesen Blechstreifen zusammengesetzte Gesamtprofil starr, so daß sich also mit dieser Einlage Stufen von beliebiger Rundung oder auch gerade Stufen nicht herstellen lassen. Es sind ferner zwar auch schon . Formen bekannt, welche entweder ganz aus Gummi bestehen oder deren formgebende Flächen aus Gummi hergestellt sind. Obschon hier Gummi zur Verwendung kommt, ist die Form nicht biegsam und kann immer nur für denselben Gegenstand in Bezug auf Form und Größe gebraucht werden.Interchangeable molded insert for the production of profiled stairs In the factory-made production of profiled, rounded stair treads, the Profile either through corresponding wood or gypsum inlays of the stair step shape generated. By the shown in the figure, forming the subject of the invention Mold insert, the production of these steps is very simplified. This molded insert consists of an elastic rubber strip together with an elastic sheet steel protective strip. With this elastic profile insert, steps in every bend and Create rounding. There are already profile inserts made of sheet metal for stair tread shapes known, in which elastic use is found in addition to the rigid sheet iron strips, however, the overall profile composed of these sheet metal strips is rigid, see above that with this insert there are steps of any rounding or even straight Do not have steps made. Furthermore, there are already. Forms known, which either consist entirely of rubber or their shaping surfaces are made of rubber are made. Although rubber is used here, the shape is not flexible and can only ever be used for the same object in terms of shape and size will.
Im Gegensatz hierzu gestattet die den Gegenstand der Erfindung bildende Einlage für Treppenstufenformen eine Veränderung des Formlings in Form und Größe. Außerdem hat die profilierte, biegsame Gummieinlage gemäß der Erfindung gegenüber bereits bekannten anderen elastischen Formeinlagen folgende Vorzüge: r. ist Gummi weitgehendst biegsam, 2. besteht diese Einlage aus einem Stück und ist infolgedessen leicht zu reinigen, 3. dichtet Gummi denVorsatzbeton der Stufe vollkommen ab, wodurch eine saubere Stufe ohne besondere Nachbearbeitung gewährleistet wird, und q.. ist Gummi so gut wie keinem Verschleiß ausgesetzt. Der elastische, biegsame Stahlblechstreifen a, an dem sich das Gummiprofil b, c oder d anlegt, dient zur Versteifung des Gummiprofils während der Herstellung der Treppenstufe.In contrast to this, the insert for stair tread shapes forming the subject of the invention allows the molding to be changed in shape and size. In addition, the profiled, flexible rubber insert according to the invention has the following advantages over other known elastic molded inserts: r. rubber is largely flexible, 2. this insert consists of one piece and is therefore easy to clean, 3. rubber seals the facing concrete of the step completely, which ensures a clean step without any special post-processing, and q .. rubber is as good as none Exposed to wear and tear. The elastic, flexible sheet steel strip a, on which the rubber profile b, c or d rests, is used to stiffen the rubber profile during the manufacture of the step.
In Längsansicht und Querschnitt zeigen: Abb. i den mit a bezeichneten Stahlblechstreifen, Abb. 2 ein Gummiprofil b mit anliegendem Stahlblechstreifen a.In longitudinal view and cross-section show: Fig. I denoted by a Sheet steel strips, Fig. 2 a rubber profile b with an adjacent sheet steel strip a.
In Abb. 3 und q. sind mit c bzw. d andere gebräuchliche Treppenstufenprofile bezeichnet, die ebenfalls in der zuvor beschriebenen Art zur Herstellung von Treppenstufen Ver-. Wendung finden.In Fig. 3 and q. are designated with c and d other common stair nosing profiles, which are also used in the manner described above for the production of stair treads. Find a turn.
Abb. 5 veranschaulicht eine Treppenstufenform e in Oberansicht, die mittels Schraubzwingen zusammengehalten wird. In diese Form sind die elastischen Profileinlagen b gemäß Abb.2 derart eingebaut, daß der Betonfüllraum i eine Treppenstufe mit zwei abgerundeten Ecken bildet. Die Hohlräume f und g werden mit Sand o. dgl. ausgefüllt, damit die Profileinlage b bei der Herstellung ihre Lage beibehält.Fig. 5 illustrates a stair step shape e in top view, the is held together by means of screw clamps. In this form the elastic ones are Profile inserts b installed in accordance with Fig. 2 in such a way that the concrete filling space i is a step with two rounded corners. The cavities f and g are covered with sand or the like. filled in so that the profile insert b retains its position during manufacture.
Abb. 6 zeigt den Querschnitt k der Abb. 5 in etwas größerem Maßstabe. Beide Abbildungen lassen erkennen, daß Treppenstufen auf Grund der Biegsamkeit der Profileinlagen in jeder gewünschten Rundung hergestellt werden können.Fig. 6 shows the cross section k of Fig. 5 on a slightly larger scale. Both images show that stairs due to the flexibility of the Profile inserts can be produced in any desired curvature.
Abb. 7 zeigt den Querschnitt einer Treppenstufe, die mit Hilfe der in Abb. 5 dargestellten Form hergestellt werden kann.Fig. 7 shows the cross-section of a stair step, which is made with the help of the Form shown in Fig. 5 can be produced.
