Description
Stahlleichtträger werden vielfach aus Einzelprofilen zusammengeschweißt,-wobei als Verbindung aus Ersparnisgründen entweder die PunktschweiBung oder die unterbrochene Streckenschweißung zur Anwendtn@g °,@eW,"gt. Um ein Profil mit möglichst guten statischen Eigenschaften zu erhalten, werden zu seinem Aufbau vielfach verschiedenartige Profile verwendet, worunter die wirtschaftliche liertigung leidet. Auch sind Schweißverbindungen oft durch die von den Auflasten ausgelösten Querkräfte beansprucht.Lightweight steel girders are often welded together from individual profiles as a connection for reasons of economy, either the spot weld or the interrupted one Section welding to apply @ g °, @ eW, "gt. To create a profile with the best possible static To maintain properties, its structure often results in different types of profiles used, which affects the economic downturn. Also are welded joints often stressed by the shear forces triggered by the loads.
Der Stahlleichtträger nach der Erfindung vermeidet die genannten Nachteile. Er ist so ausgebildet, daß zwischen zwei aus U-förmig abgekanteten Bandstählen gebildeten Flanschen, deren A.bkantungen einander zugekehrt sind, ein Steg aus einem weiteren U-förmig abgekanteten Bandstahl oder aus mehreren solchen Bandstählen so eingeschweißt ist, daß der Schwerpunkt des 5tegpröfils auf die gemeinsame Schwerachse der Flanschenprofile zu liegen kommt. Die für Flansche und Steg verwendeten U-Profile sind vollkommen gleichartig, lassen sich sehr wirtschaftlich herstellen und auch als Einzelprofile gut hantieren, ohne der Gefahr des Verbiegens ausgesetzt zu sein. Sie gestatten die Fertigung verschieden hoher und breiter Träger mit wenigen U-Profilen. Der aus der Mitte gerückte Steg sichert dem Träger die volle Ausnutzung seines Querschnittes bei Biegung um die parallel zu den Flanschen laufende Schwerachse und erhöht das Trägheitsmoment um die parallel zum Steg laufende Achse.The lightweight steel beam according to the invention avoids the disadvantages mentioned. It is designed so that formed between two U-shaped folded steel strips Flanges, the edges of which are facing each other, a web from another U-shaped folded steel strip or from several such steel strips welded in this way is that the focus of the 5tegpröfils is on the common center of gravity of the flange profiles comes to rest. The U-profiles used for the flanges and web are perfect similar, can be produced very economically and also as individual profiles handle it well without being exposed to the risk of bending. You allow the production of different heights and widths with a few U-profiles. The out the bar, which is moved in the middle, ensures that the wearer can make full use of its cross-section when bending around the center of gravity running parallel to the flanges and increases this Moment of inertia about the axis running parallel to the web.
Nach einem weiteren Erfindungsgedanken sind die Abkantungen des Steges mit den Flanschen durch zickzackförmig angeordnete Punkt- oder Streckenschweißung verbunden. Die Schweißpunkte oder Streckennähte, deren Anzahl durch die Abmessungen des Trägers bedingt ist, verleihen nun gleichzeitig den .Flanschen zusätzlichen Halt gegen Verkanten.According to a further idea of the invention, the bevels of the web with the flanges by zigzag point or section welding tied together. The weld points or line welds, the number of which depends on the dimensions the carrier is conditional, now lend the .Flange additional Hold against tilting.
Durch den Vorschlag der Verwendung mehrerer U-förmig abgekanteter Bandstähle wird die Vielseitigkeit der Gestaltung des neuen Profils erhöht. Mit einem einzigen U-Profil lassen sich verschiedene Stahlträger herstellen, außerdem ist das Profil versteift, da der Steg beulsicher ist.By suggesting the use of several U-shaped bevels Strip steel increases the versatility of the design of the new profile. With Various steel girders can also be made from a single U-profile the profile is stiffened because the bar is dent-proof.
Die Abb. i bis 3 geben Ausführungsbeispiele. Abb. 2 ist ein Schnitt durch den Steg von Abb. i. Der Stahlleichtträger nach Abb. i und 2 setzt sich aus zwei U-förmig abgekanteten Flanschen i und 2 zusammen, zwischen die ein ebenfalls U-förmig abgekanteter Bandstahl 3 als Steg eingeschweißt ist. Der Steg ist aus der Mitte verschoben, damit bei der Belastung des Trägers eine gleichmäßige Spannungsverteilung erfolgt. Die Schweißpunkte q. und 5 zur Verbindung des Steges mit den Flanschen liegen nicht hintereinander, sondern sind zickzackförmig angeordnet, wie es Abb. 2 zeigt.Figs. I to 3 show exemplary embodiments. Fig. 2 is a section through the web of Fig. i. The lightweight steel beam according to Fig. I and 2 is exposed two U-shaped beveled flanges i and 2 together, between which one also U-shaped folded steel strip 3 is welded as a web. The jetty is off Center shifted so that the stress is evenly distributed when the girder is loaded he follows. The welding points q. and 5 for connecting the web to the flanges do not lie one behind the other, but are arranged in a zigzag, as shown in Fig. 2 shows.
Abb. 3 stellt einen Träger dar, der nur aus völlig gleichen U-förmig abgekanteten Bandstählen 6 gebildet wurde. Er ist infolge der Stegverstärkung sehr tragfähig, auch in bezug auf Knickbeanspruchung. Der Vorteil einer solchen Anordnung liegt in der Möglichkeit zur Schaffung einer großen Zahl wirtschaftlicher Profile mit wenig Grundprofilen. Aus zwei Grundprofilen läßt sich z. B. leicht ein Dutzend und mehr wirtschaftlicher Träger nach der erfindungsgemäßen Form herstellen.Fig. 3 shows a carrier that is only made up of completely identical U-shaped folded steel strips 6 was formed. It is very good due to the web reinforcement load-bearing, also with regard to buckling stress. The advantage of such an arrangement lies in the possibility of creating a large number of economic profiles with few basic profiles. From two basic profiles z. B. easily a dozen and make more economical carriers according to the form of the present invention.
