Description
2020th
Die Erfindung betrifft einen Stahlträger, insbesondere für den Gebäudebau, mit in den Ecken einer rechteckigen Umrißlinie angeordneten, zueinander parallelen L-Profilstäben, mit hiervon im rechten Winkel und in Richtung der langen Rechteckseiten verlaufenden, einander paarweise gegenüberliegenden und die jeweiligen L-Profilstäbe paarweise miteinander verbindenden Strebenelementen und mit Verstrebungsmitteln, welche die L-Profilstäbe sowohl diagonal mit einheitlicher Neigung in Richtung der langen Rechteckseiten als auch quer zu den Strebenelementen miteinander verbinden.The invention relates to a steel beam, in particular for building construction, with arranged in the corners of a rectangular outline, to each other parallel L-profile bars, with them at right angles and in the direction of the long sides of the rectangle extending, opposite to each other in pairs and the respective L-profile bars in pairs with one another connecting strut elements and with bracing means, which the L-profile bars both diagonally with uniform inclination in the direction of the long sides of the rectangle and across the strut elements connect with each other.
Bei einem aus der Zeitschrift »Acier-Stahl-Steel«, Heft Nr. 5/1968, Seite 219 bekannten Stahlträger dieser Art bestehen die Verstiebungsmhtel einerseits aus an den langen Querschnittsseiten gelegenen, zu den L-Profilstäben geneigten Diagonalstreben und andererseits an den kurzen Querschnittsseiten gelegenen, zu den L-Profilstäben winkelrecht stehenden Querstreben. Die Diagonalstreben und die Querstreben bestehen dabei ebenfalls aus L-Profilstäben.With one from the magazine »Acier-Stahl-Steel«, Issue No. 5/1968, page 219 known steel girders of this Art, on the one hand, the displacement funds consist of an the long cross-section sides, inclined to the L-profile bars, and on the other hand, diagonal struts Cross struts on the short cross-section sides at right angles to the L-profile bars. The diagonal struts and the cross struts also consist of L-profile bars.
Der Erfindung liegt die Aufgabe zugrunde, bei der Montage eines Stahlträgers der eingangs genannten Art den Arbeitsaufwand für die Anordnung der Verstrebungsmittel zu vermindern. Dies soll erfindungsgemäß dadurch erreicht werden, daß die Verstrebungsmittel aus je einem flachen, H-förmigeri Stegteil mit an den diagonal verlaufenden parallelen Außenrändern rechtwinklig abstehenden Flanschen bestehen und die Flansche an den in der langem Rechteckseite der rechtwinkligen Umrißlinie gelegenen Schenkeln der L-Profilstäbe anliegen und an denselben befestigt sind.The invention is based on the task of assembling a steel beam of the type mentioned at the beginning to reduce the amount of work involved in arranging the bracing means. This is intended according to the invention can be achieved in that the bracing means each from a flat, H-shaped web part with to the There are diagonally extending parallel outer edges and the flanges protruding at right angles Flanges on the legs of the L-profile bars rest and are attached to the same.
mittel ersetzen also sowohl die Diagonal- wie auch die Querstreben des bekannten Stahlträgers. Daraus ergibt ach als eister Vorteä eine bauliche Vereinfachung mit damit eingehender Verminderung des Arbeitsaufwandes für die Montage. Medium replace both the diagonal and the cross struts of the well-known steel girder. From this it follows Oh, as a great Vorteä a structural simplification with thus a more detailed reduction in the amount of work required for assembly.
In statischer Hinsicht ergibt sich ein weiterer gewichtiger Vorteil daraus, daß die erfindungsgemäß vorgesehenen Veretrebungsmittel den Stahlträger gegen Verformung seines rechteckförmigen Querschnittes zu einem Parallelogramm (bei exzentrischer Belastung) versteifen.From a static point of view, there is another significant advantage that the invention provided means of support against the steel girder Deformation of its rectangular cross-section to a parallelogram (with eccentric loading) stiffen.
Ein weiterer Vorteil ergibt sich daraus, daß der Stahlträger infolge des Wegfalles der Querstreben auf seiner ganzen Länge an den kürzeren Seiten seines Querschnittes offen ist Es können also von beiden offenen Querseiten her in den Stahlträger hindernisfrei allerlei Leitungsrohre eingelegt werden, und zwar auch dann noch, wenn der Stahlträger beispielsweise zusammen mit anderen solchen Trägern und mit Säulen bereits einem Gebäude-Stahltragwerk einverleibt worden istAnother advantage results from the fact that the steel girder due to the omission of the cross struts its entire length is open on the shorter sides of its cross-section. It can therefore be used by both Open transverse sides of all kinds of conduits can be inserted into the steel girder without any obstacles, and that too then even if the steel beam, for example, together with other such beams and with columns has already been incorporated into a building steel structure
Ein Ausführungsbeispiel der Erfindung wird nachfolgend an Hand der Zeichnung erläutertAn exemplary embodiment of the invention is explained below with reference to the drawing
Die Figur zeigt eine perspektivische Ansicht einer auf einer Stockwerkhöhe gelegenen Partie eines Tragwerkes, in dem mehrere erfindungsgemäß ausgebildete Stahlträger vorhanden sind Diese sind einheitlich mit I bezeichnet Jeder dieser Stahlträger weist als wichtigste TeileThe figure shows a perspective view of a part of a supporting structure located at floor level, in which there are several steel girders designed according to the invention. These are uniformly marked with I. Each of these steel girders has as the most important parts
a) in den Ecken einer rechteckigen Umrißlinie angeordnete, zueinander parallele L-Profilstäbe 2,a) parallel L-profile bars 2 arranged in the corners of a rectangular outline,
b) auf der Länge des Trägers gleichmäßig verteilte, in Richtung der langen Rechteckseiten verlaufende, einander paarweise gegenüberliegende und die L-?rofilstäbe paarweise miteinander verbindende Strebenelemente 3, undb) evenly distributed along the length of the girder, running in the direction of the long sides of the rectangle, opposing one another in pairs and connecting the L-profile rods to one another in pairs Strut elements 3, and
c) in den zwischen solchen Strebenelementen 3 gelagenen Trägerlängsabschnitten und in den an beiden Enden des Trägers gelegenen Trägerlängsabschnitten angeordnete Versirebungsmittel 4c) in the girder longitudinal sections located between such strut elements 3 and in the Sizing means 4 arranged at both ends of the girder in longitudinal girder sections
Jedes dieser Verstrebungsmittel 4 hat einen flachen, H-förmigen Stegteil 4a und zwei von den parallelen Außenrändern dieses Stegteiles rechtwinklig abstehende Flansche 4b; dabei verlaufen die Stegteile 4a aller dieser Verbindungselemente 4 unter einheitlicher Neigung von etwa 40° bis 60° zu den durch die Verstrebungsmittel 4 miteinander verbundenen L-Profilstäben 2 und in Richtung der kurzen Rechteckseite des Trägerquerschnittes; die Flansche 4b liegen innenseitig an den jeweiligen Schenkeln der L-Profilstäbe an und sind an denselben befestigt (Neben diesen Flanschen der beim Ende jedes Trägers 1 gelegenen Verstrebungsmittel 4 sind zudem Flacheisenstäbe 5 vorgesehen, die außenseitig an den eben erwähnten L-Profilstabschenkeln anliegen und an ihnen befestigt sind).Each of these bracing means 4 has a flat, H-shaped web part 4a and two flanges 4b protruding at right angles from the parallel outer edges of this web part; The web parts 4a of all these connecting elements 4 run at a uniform inclination of about 40 ° to 60 ° to the L-profile rods 2 connected to one another by the bracing means 4 and in the direction of the short rectangular side of the carrier cross-section; the flanges 4b rest on the inside of the respective legs of the L-profile rods and are attached to them (in addition to these flanges of the bracing means 4 located at the end of each girder 1, flat iron rods 5 are also provided, which rest on the outside of the L-profile rod legs just mentioned attached to them).
Zur Befestigung der Teile 3, 4 und 5 an den L-Profilstäben 2 dienen wie üblich Schraub- und/oder Nietbolzen 6; diese sind in der Zeichnung größtenteils weggelassen.To fasten the parts 3, 4 and 5 to the L-profile bars 2, screw and / or are used as usual Rivet bolt 6; these are largely omitted in the drawing.
