Description
Es ist bekannt, daß bei geschweißten Blechträgern besonders dicke Gurtungen aus hochwertigem Stahl zu Spröd'brüchen neigen. Diese Erkenntnis hatte zur Folge, daß man heute dicke Gurtungen nur ungern oder gar nicht mehr verschweißt.It is known that welded sheet metal girders are particularly thick Belts made of high quality steel tend to break brittle. Had this realization As a result, thick belts are nowadays only welded reluctantly or not at all.
Man hat erfahren, daß man beim Schweißen dicktenabhängig ist. Je dicker also der Querschnitt, desto größer ist die Gefahr des Sprödbruches. Infolge des Überganges des flüssigen Elektrodenmaterials auf die große Masse, der Gurtung wird beim Schweißen eine nicht gewünschte Abschreckwirkung hervorgerufen, die jene großen mehrachsigen Spannungen erzeugt, die zum -Sprödbruch führen. Gleichzeitig verhindert der vorhandene dicke Querschnitt denAbbau der Spannungsspitzen.It has been learned that welding is dependent on thickness. The thicker so the cross-section, the greater the risk of brittle fracture. As a result of the Transition of the liquid electrode material to the large mass that is girdling caused an undesirable quenching effect during welding, which is great multiaxial stresses are generated, which lead to brittle fracture. At the same time prevented the existing thick cross-section reduces the stress peaks.
Die Hüttenwerke haben durch metallurgische Maßnahmen versucht, einen Baustahl herzustellen, der auch in besonders dicken Abmessungen nicht zu Sprödbrüchen neigen soll. Bisher ist es jedoch nicht gelungen, auf diesem Wege eine befriedigende Lösung herbeizuführen.The smelting works have tried to use metallurgical measures Manufacture structural steel that does not cause brittle fractures even in particularly thick dimensions should tend. So far, however, it has not been possible to find a satisfactory one in this way Bring about solution.
Einen neuen Weg, die Dicktenabhängigkeit beim Schweißen von dicken Gurtungen durch konstruktive Maßnahmen zu überwinden, zeigt erfindungsgemäß das Gurtprofil mit eingewalztem Stegblechanschlußwinkel, beispielsweise dargestellt in den Abb. i bis 4. Bei den Wulstprofilen ist gerade an der Stelle, an der die Stegblechanschlußnaht geschweißt werden muß, eine Baustahlverdickung, die das Abschrecken und somit die Aufhärtung des Baustahles begünstigt bzw. den Abbau der Spannungsspitzen verhindert. Bei einem neueren Gurtprofil mit einem Winkelstahl als Bindeglied ist die Absicht zu erkennen, die Abschreckwirkung zu mindern, indem die Anschlußnähte aus der Mitte ,der Gurtung, wo sie sich am ungünstigsten auswirken, herausgelegt sind. Diese Art des Gurtanschlusses hat sich, wahrscheinlich wegen der etwas umfangreichen Schweißarbeit, nicht eingeführt.A new way, the thickness dependency when welding thick Overcoming belts by constructive measures shows that according to the invention Belt profile with rolled-in web plate connection angle, shown for example in Fig. i to 4. With the bead profiles is just at the point where the Web plate connection seam must be welded, a structural steel thickening that quenching and thus the hardening of the structural steel is favored and the stress peaks are reduced prevented. In a newer belt profile with an angle steel as a link the intention to recognize the deterrent effect by removing the connection seams from the middle, the straps, where they have the most unfavorable effect, laid out are. This type of belt connection has proven itself, probably because of the somewhat extensive Welding work, not introduced.
Das Gurtprofil nach der Erfindung mit eingewalztem Stegblechanschlußwinkel hat im Gegensatz zu den Wulstprofilen an der Stelle des Stegblechanschlusses keine Verdickung bzw. Materialanhäufung, sondern eine Baustahlminderung, die ein schnelles Abfließen der Wärine (Abschrecken) und damit Aufhärtungen verhindert. Die Ausführung bietet durch den eingewalzten Winkel einen allmählichen Übergang vom schwachen Stegblech zur starken Gurtung. Sie kann Spannungsspitzen leicht abbauen und dadurch dynamischen Beanspruchungen besser standhalten als die bisher bekannten. Der eingewalzte Winkel erhöht die Drucksteifigkeit der Gurtung erheblich. Die offene Seite des Winkels kann durch eingelegte schmale Flachstähle, wie in Abb. i und 4 angegeben, oder durch eine zweite Gurtplatte nach Abb. 2 und 3 geschlossen werden. Die Sch-%N-eißnähte der neuen Gurtung sind leicht zugänglich und daher gut zu schweißen.The belt profile according to the invention with a rolled-in web plate connection angle In contrast to the bulge profiles, it does not have any at the point of the web plate connection Thickening or accumulation of material, but a reduction in structural steel that a rapid Drainage of the heat (quenching) and thus prevents hardening. Execution Thanks to the rolled-in angle, it offers a gradual transition from the weak web plate for strong strapping. It can easily reduce stress peaks and thereby become dynamic Withstand stresses better than those previously known. The rolled-in angle increases the compressive rigidity of the harness considerably. The open side of the angle can be through inserted narrow flat steel, as indicated in fig. i and 4, or through a second belt plate according to Fig. 2 and 3 can be closed. The welding seams the new straps are easily accessible and therefore easy to weld.
