Description
Treppe Die Erfindung bezweckt die Herstellung von Treppen, die durch Aneinanderreihen fertiger Stufen hergestellt werden.Staircase The invention aims to manufacture stairs that go through Lining up finished steps are produced.
Der Erfindungsgegenstand zeigt in Abb. t den Querschnitt einer massiven Treppe, in Abb. a den Querschnitt einer Metalltreppe. Zweck der Erfindung ist die wirtschaftliche Verwendung des Baustoffes. Es werden die Hauptmassen dieser Stufen in Zonen angeordnet, an denen die größten Beanspruchungen auftreten. Dadurch ist es möglich, bei den üblichen Spannweiten mit den meist verwendeten feuerfesten, aber nur geringe Zugfestigkeit aufweisenden Baustoffen ohne besondere zugfeste Einlagen auszukommen. In den Fällen, in denen diese erforderlich werden, ist ihre sichere Befestigung und ihre wirtschaftliche Anordnung besonders leicht möglich. Erfindungsgemäß erhalten die einzelnen Stufen a eine Querschnittsform, die der Form des Buchstabens Z entspricht. Durch diese Form wird die Anordnung der Hauptmassen an den meist beanspruchten Stellen gewährleistet. Die Stufen a werden so aneinandergereiht, daß der Obergurt c der einen Stufe a mit dem Untergurt d der folgenden Stufe a ip einer Ebene liegt und die Gurte sich an ihren äußeren Kantene berühren.The subject of the invention shows in Fig. T the cross-section of a massive Staircase, in Fig. A the cross-section of a metal staircase. The purpose of the invention is economical use of the building material. It will be the main masses of these stages arranged in zones where the greatest stresses occur. This is it is possible to use the most commonly used refractory, but only low tensile strength building materials without special tensile strength inserts get along. In those cases where these are required, your safe one Attachment and their economical arrangement are particularly easy. According to the invention the individual stages a receive a cross-sectional shape that corresponds to the shape of the letter Z corresponds to. This shape ensures that the main masses are arranged on the most stressed ones Places guaranteed. The steps a are lined up so that the top chord c of one level a with the lower chord d of the following level a ip is one level and the straps touch on their outer edges.
