Description

Die Erfindung betrifft einen feuerwiderstandsfähigen Verbundträger für Stützen, Lichtbandträger oder dergl., bestehend aus einem offenen Stahlprofil, dessen Hohlräume mit Beton ausgefüllt sind, wobei an den Innenwänden des Stahlprofiles Verbundmittel angeordnet sind, die in die mit Beton gefüllten Hohlräume ragen und mit dem Beton verbunden sind.The invention relates to a fire-resistant composite girder for supports, light band girders or the like, consisting of an open steel profile, the cavities of which are filled with concrete, compound materials being arranged on the inner walls of the steel profile, which project into the cavities filled with concrete and are connected to the concrete are.

Von mit Beton ausgefüllten Walzträgern, insbesondere Breitflanschträgern, deren Flansche außen aber ungeschützt bleiben, ist bekannt, daß sie eine erhöhte Feuerwiderstandsdauer, z.B. die Feuerwiderstandsklasse F 9o nach DIN 41o2 erreichen, wenn sie zusätzlich durch eingelegte Rundstähle entsprechend bewehrt sind und der Beton mit dem Steg durch Verdübelungsmittel verbunden ist. Diese bekannten Verbundträger haben aber den Nachteil, daß die zusätzlichen Bewehrungs- und Verdübelungsarbeiten sehr zeitaufwendig und lohnintensiv sind. Von daher ist es Aufgabe der Erfindung, einen Verbundträger der eingangs genannten Art zu schaffen, bei dem ohne nachträglichen zusätzlichen Brandschutz die zusätzlichen Bewehrungs- und Verdübelungsarbeiten eingespart werden können.Roller supports filled with concrete, in particular wide flange supports, the flanges of which remain unprotected on the outside, are known to have an increased fire resistance duration, e.g. achieve fire resistance class F 9o according to DIN 41o2 if they are additionally reinforced by inserted round steel and the concrete is connected to the bridge by means of anchoring agents. However, these known composite beams have the disadvantage that the additional reinforcement and dowelling work is very time-consuming and costly. It is therefore an object of the invention to provide a composite girder of the type mentioned in the introduction, in which the additional reinforcement and dowelling work can be saved without subsequent additional fire protection.

Nach der Erfindung wird die Aufgabe in der Weise gelöst, daß das Stahlprofil aus einem Strangpreßprofil besteht, das z.B. einen I,

Figure imgb0001
,
Figure imgb0002
profilähnlichen oder auch einen anderen offenen Querschnitt hat und dessen Innenseiten abstehende dünnwandige Stege aufweisen und/oder profiliert sind. In zweckmäßiger Weise sind die abstehenden dünnwandigen Stege an ihren freien Enden mit wulstartigen Verdickungen'versehen, die die Bewehrung darstellen. Zur Verbesserung der Haftverbundwirkung sind die Innenseiten des Strangpreßprofiles stufenförmig, sägezahnartig, schwalbenschwanzförmig, wellenförmig oder in anderer die Oberfläche vergrößernder Weise profiliert. Auch können die abstehenden dünnwandigen Stege mit Baustahlmattenstreifen oder Drahtgittern verschweißt sein, wodurch eine weitere Verbesserung der Tragfähigkeit besonders im Brandfall erreicht werden kann. Die Verbundwirkung wird in vorteilhafter Weise dadurch unterstützt, daß die Flanschenden des Strangpreßprofiles rechtwinklig abgebogen sind und den Beton einfassen, so daß der Beton im Brandfall gegen Herauslösen zusätzlich gesichert ist.According to the invention, the object is achieved in such a way that the steel profile consists of an extruded profile which, for example, has an I,
Figure imgb0001
,
Figure imgb0002
has a profile-like or another open cross-section and the insides of which have protruding thin-walled webs and / or are profiled. The projecting thin-walled webs are expediently provided at their free ends with bulge-like thickenings which represent the reinforcement. In order to improve the adhesive bond effect, the inner sides of the extruded profile are profiled step-like, sawtooth-like, dovetail-shaped, undulating or in some other way enlarging the surface. The protruding thin-walled webs can also be welded to structural steel mat strips or wire grids, which can further improve the load-bearing capacity, particularly in the event of a fire. The composite effect is advantageously supported in that the flange ends of the extruded profile are bent at right angles and surround the concrete, so that the concrete is additionally secured against loosening in the event of a fire.

Bei z.B. I-förmigen und mehrteiligen zusammengesetzten

Figure imgb0003
-förmigen Querschnitten des Strangpreßprofiles ist es zweckmäßig, daß das Strangpreßprofil unterschiedliche Wandstärken besitzt, und zwar derart, daß die beidseitig von Beton umgebenen Stege dicker sind als die, die nur von einer Seite mit Beton bedeckt sind. Schließlich ist es in diesen Fällen aus Gründen der geringeren Wärmeleitfähigkeit von Vorteil, daß die Übergangsbereiche der beidseitig mit Beton bedeckten Stege zu den einseitig mit Beton bedeckten dünnwandiger sind als die mittleren Teile der Stege.For example, I-shaped and multi-part composite
Figure imgb0003
-shaped cross-sections of the extruded profile, it is expedient that the extruded profile has different wall thicknesses, in such a way that the webs surrounded on both sides by concrete are thicker than those which are only covered with concrete from one side. Finally, in these cases, for reasons of lower thermal conductivity, it is advantageous that the transition areas of the webs covered on both sides with concrete to the one-sided concrete walls are thin-walled than the middle parts of the webs.

Die Vorteile des Verbundträgers nach der Erfindung sind insbesondere darin zu sehen, daß er eine Feuerwiderstandsdauer von mindestens 9o Minuten ohne zusätzlichen Brandschutz wie z.B. Bewehrungen und Stahldübel, deren nachträgliche Anbringung erheblichen Zeit- und Kostenaufwand bedeutet, hat. Bei dem erfindungsgemäßen Verbundträger wird die erhöhte .Tragfähigkeit im Brandfall z.B. durch die homogene Ausbildung von Stegen und Profilierungen der Innenseiten bei der Herstellung des Strangpreßprofiles selbst mit ausgebildet. Die Möglichkeiten der Strang- . preßtechnik sind zwar hinsichtlich der Größe der Profile begrenzt, aber die Vorteile der integrierten Bewehrung und des optimalen Haftverbundes lassen sich doch bei einer Reihe von Tragkonstruktionen, für die eine höhere Feuerwiderstandsdauer gefordert wird, unter Verzicht auf besondere Brandschutzmaßnahmen ausnutzen. Dia Bauweisenach der Erfindung ist deshalb besonders wirtschaftlich, weil die Tragfähigkeit des Strangpreßprofiles in Stahl/Beton-Verbundweise etwa 3o% höher als die des reinen Stahlprofils liegt, wodurch sich die Mehrkosten der Strangpreßtechnik und der Betonfüllung bezahlt machen, unbeschadet des Wegfalls des Brandschutzes.The advantages of the composite girder according to the invention can be seen in particular in that it has a fire resistance duration of at least 90 minutes without additional fire protection, e.g. Reinforcements and steel dowels, the subsequent installation of which requires considerable time and cost. In the composite beam according to the invention, the increased load-bearing capacity in the event of a fire is e.g. formed by the homogeneous formation of webs and profiles of the inner sides in the manufacture of the extruded profile itself. The possibilities of strand. Press technology is limited in terms of the size of the profiles, but the advantages of the integrated reinforcement and the optimal adhesive bond can be exploited in a number of supporting structures, for which a longer fire resistance is required, without special fire protection measures.
