Abstract

The steel section is rolled in one piece, having a flat base and two flanges. Each flange is positioned inside the base a distance of one quarter of the base length and has the same height above the base. This gives a modular section of high resistance to bending. It can be joined to other beams of the same profile, or to standard beams, to build complex structures and gives savings in cost, time and materials.

Description

Gewalztes Stahlprofil Die vorliegende Erfindung betrifft ein gewalztes Stahlprofil von neuartiger Querschnittsform. Rolled steel profile The present invention relates to a rolled steel profile Steel profile with a new cross-sectional shape.

Die Erfindung bezweckt in erster Linie die Schaffung eines gewalzten Stahlprofils, dessen Querschnitt so gestaltet und berechnet ist, dass sich bei der Erstellung von Stahlkonstruktionen -Einsparungen bis zu 30 % gegenüber den Erstellungskosten entsprechender Konstruktionen mit herkömmlichen Profilen, beispielsweise U-Profilen, Profilen und dergleichen erzielen lassen. Eingehende Untersuchungen, Prüfungen und sorgfältige Studien durch Fachleute haben ergeben, dass Dank dem neuen Profil gemäss vorliegender Erfindung die Gesamtkosten von Stahlkonstruktionen wie Stützen, Trägern und Fachwerken, insbesondere durch Einsparung von Arbeitszeit erheblich gesenkt werden können. Für das neue Profil wurden auch besondere Normen ausgearbeitet, auf welche später eingehender eingegangen wird.The primary aim of the invention is to provide a rolled one Steel profile, the cross-section of which is designed and calculated in such a way that the Creation of steel structures - savings of up to 30% compared to the construction costs corresponding constructions with conventional profiles, for example U-profiles, Allow profiles and the like to be achieved. Incoming Investigations, Tests and careful studies by professionals have shown that thanks to the new Profile according to the present invention the total cost of steel structures such as Supports, girders and trusses, especially by saving considerable working time can be lowered. Special standards have also been developed for the new profile, which will be discussed in more detail later.

Der Lrfindung liegt ausserdem die Aufgabe zugrunde, ein neues gewalztes Stahlprofil mit hervorragenden Festigkeitseigenschaften, insbesondere gegen Biege- und Druckbeanspruchungen zu schaffen.The invention is also based on the task of producing a new rolled Steel profile with excellent strength properties, especially against bending and to create compressive stresses.

Um die bereits erwähnte Herabsetzung von Montagezeiten zu erzielen wurde bei der Schaffung des neuen Profils besonders darauf geachtet, dass dieses Profil in besonders einfacher Weise zu Bauelementen hoher Festigkeit verbunden, insbesondere verschweisst werden kann. Das erfindungsgemässe Profil kann besonders einfach mit gleichartigen oder herkömmlichen Stahlprofilen zu einer Vielzahl verschiedenartiger Bauelemente wie Stützen und Fachwerken einfachen Aufbaus und hoher Festigkeit vereinigt werden.In order to achieve the already mentioned reduction of assembly times When creating the new profile, particular care was taken to ensure that this Profile connected in a particularly simple way to form high-strength components, in particular can be welded. The profile according to the invention can particularly simply with similar or conventional steel profiles to a multitude of different types Structural elements such as columns and trusses of simple construction and high strength are combined will.

Das erfindungsgemässe gewalzte Stahlprofil ist dadurch gekennzeichnet, dass es im Querschnitt eine flache Basis und zwei einseitig quer zu derselben stehende Schenkel im Abstand von den Aussenkanten der Basis aufweist, derart, dass das Profil vier freie Flansche hat, von welchen zwei durch die ausserhalb der Schenkel liegenden Ränder der Basis und die beiden anderen durch die Schenkel gebildet sind. Dieses Profil weist, wie erwähnt, hohe Festigkeit und Stabilität auf und gestattet Dank seiner vier freien Flansche eine einfache und vielseitig Vereinigung mit gleichartigen und bestehenden Stahlprofilen.The rolled steel profile according to the invention is characterized in that that it has a flat base in cross-section and two standing transversely to it on one side Has legs at a distance from the outer edges of the base, such that the profile has four free flanges, two of which through those lying outside the legs Edges of the base and the other two are formed by the legs. This As mentioned, profile has high strength and stability and allows thanks its four free flanges a simple and versatile union with like and existing steel profiles.

Im folgenden wird die Erfindung anhand der Zeichnung näher erläutert, die ein Ausführungsbeispiel des erfindungsgemässen Profils und einige mit Hilfe dieses Profils ausgeführte Bauelemente zeigt.In the following the invention is explained in more detail with reference to the drawing, the one embodiment of the inventive profile and some with the help This profile shows executed components.

Figur 1 zeigt den Querschnitt des neuen Stahlprofils, Figur 2 ist eine perspektivische Ansicht eines Abschnitts des Stahlprofils und Figuren 3 bis 6 zeigen Beispiele von Bauelementen die mit Hilfe des Profils gemäss Figuren 1 und 2 erstellt werden können.Figure 1 shows the cross section of the new steel profile, Figure 2 is a perspective view of a portion of the steel profile and Figures 3 to 6 show examples of components that are made with the aid of the profile according to FIGS 2 can be created.

Das gewalzte Stahlprofil 1, von welchem Figur 1 den Querschnitt zeigt, hat eine flache Basis 2 und zwei Schenkel 3, die einseitig quer zur Basis von derselben abstehen. Es ergibt sich damit ein im wesentlichen 'brückenförmiges" Profil mit vier freien Flanschen, von welchen zwei durch die ausserhalb der Schenkel 3 liegenden Randteile 2a der Basis und die zwei anderen durch Schenkel 3 selbst gebildet sind.The rolled steel profile 1, of which Figure 1 shows the cross section, has a flat base 2 and two legs 3, one side transverse to the base of the same stick out. This results in an essentially 'bridge-shaped' profile four free flanges, two of which are located outside the legs 3 Edge parts 2a of the base and the other two are formed by legs 3 themselves.

Wenn B die volle Weite der Basis 2 ist, wie in Figur 1 angedeutet, so beträgt die freie Länge B1 der Flansche 2a und der Schenkel 3 B/4. Die Dicke d der Basis 2 und der Schenkel 3 ist gleich. Folglich-beträgt der Zwischenraum zwischen den Schenkeln 3 B2 = B/2 - 2d. Der Krümmungsradius R der gerundeten Kanten und Ecken, die in Figur 1 gezeigt sind, beträgt d/2.If B is the full width of the base 2, as indicated in Figure 1, so the free length B1 of the flanges 2a and the legs 3 is B / 4. The fat d of the base 2 and the leg 3 is the same. Hence-the gap is between the legs 3 B2 = B / 2 - 2d. The radius of curvature R of the rounded edges and corners, shown in Figure 1 is d / 2.

Eine ganze Reihe von Normprofilen sind gemäss den folgenden Tabellen berechnet worden, wobei die verschiedenen Symbole die oben anhand der Figur 1 angegebene Bedeutung haben.A whole series of standard profiles are according to the following tables has been calculated, the various symbols being those given above with reference to FIG Have meaning.

F ist die Fläche des Profilquerschnitts, G ist das Gewicht per Meter und Jx-x, bzw. Jy-y sind die Trägheitsmomente in den Richtungen x-x und y-y gemäss Figur 1. Die in den untenstehenden Tabellen angegebenen Normen sind vergleichbar mit DIN-Normen, weichen aber selbstverständlich im einzelnen von denselben ab.F is the area of the profile cross-section, G is the weight per meter and Jx-x and Jy-y are the moments of inertia in the directions x-x and y-y according to Figure 1. The standards given in the tables below are comparable with DIN standards, but of course deviate from them in detail.
