Abstract

I section profile or beam (1) is made by cold rolling sheet metal. The top and bottom portions of the I section are made by first folding the sheet at right angles to the central section and then back on itself to pass back over the central section before being once more folded back underneath itself to finish adjacent the central section. Strips of sheet materla (2) are interposed between the double folded top and bottom parts of the I section to reinforce it. Z and channel sections are shown fabricated in like manner and in a modification the inlaid strip is omitted and reinforcement is achieved by making a further fold in the sheet material to produce three layers of sheet in the folded parts.

Description

Kaltprofile für Konstruktionszwecke Die Erfindung betrifft aus flachgewalztem metallischem Bandmaterial kaltgeformte Konstruktionsleichtprofile. Cold rolled sections for construction purposes The invention relates to flat rolled steel metallic strip material, cold-formed lightweight construction profiles.

Kaltprofile werden bekanntlich durch Walzen oder ggf. As is well known, cold profiles are produced by rolling or, if necessary,

Abkanten von ebenem BandmaterialS sei es Warmband, Kaltband oder Blechs im kalten Zustand zu den verschiedensten den jeweiligen Konstruktionsaufgaben angepassten Querschnittmustern geformt Neben solchen Kaltprofilen mit einer nahezu gleichen Wanddicke in allen Querschnittsteiien wurden fur besondere Zwecke auch bereits verstarkte Profile wie beispielsweise mit Sicken versehene U Profile oder mit doppeltgefalteten Flanschen versehene I-- und Z-Profile geschaffen Es werden aber insbesondere von den handelsüblichen I-U-C-Z- u.a. Profilen immer hohere Belastbarkeiten bei geringstmöglichem Gewicht anfordert. Bisher konnte dies aber, bei sonst gleichbleibenden Profilabmessungen, nur durch eine stärkere Dimensionierung der Wanddicke, d.h. durch entsprechende Auswahl des Bandmaterials erfolgen. Eine solche assnahme ist aber unwirtschaftlich, weil die Profile dann nicht nur in den massgeblichen Profilquerschnittsteilen verstärkt sind, sondern auch in den anderen Querschnittsteilen unnötigerweise rberdimensionniert sind. Eine Gewichtseinsparung wird also nicht erzXeSt. Vielmehr gehen bei stärkeren Dimensionierungen des Vormaterials die Vorteile der Kaltprofile gegenüeer den Warmprofilen immer mehr verloren.Bending flat strip materialS be it hot strip, cold strip or sheet metal when cold, adapted to a wide variety of construction tasks Cross-sectional patterns formed in addition to such cold profiles with an almost identical Wall thicknesses in all cross-sectional parts have also already been reinforced for special purposes Profiles such as beaded U-profiles or double-folded ones Flanged I and Z profiles created But it will In particular, the commercially available I-U-C-Z and other profiles have increasingly higher load capacities with the lowest possible weight. So far, however, this has remained unchanged Profile dimensions, only through a greater dimensioning of the wall thickness, i.e. through appropriate selection of the tape material. But such an assumption is uneconomical because the profiles then not only in the relevant profile cross-sectional parts are reinforced, but also unnecessarily overdimensioned in the other cross-sectional parts are. A weight saving will therefore not be achieved. Rather go with stronger ones Dimensioning of the raw material the advantages of cold profiles compared to hot profiles more and more lost.

Der Erfindung liegt daher die Aufgabe zugrunde, Kaitprofile aus Metall-, insbesondere Stahlband, so auszubilden, dass ein optima es Verhältnis von Metergewicht zu statischen Eigenschaften erreicht wird. The invention is therefore based on the object of Kait profiles made of metal, in particular steel strip, to be designed in such a way that an optimal ratio of weight per meter is achieved to static properties is achieved.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Materialanhäufung in den für die Erhöhung der statischen Weite massgeblichen Profilteile durch wenigstens einen vorzugsweise eingelegten Materialstreifen erhöht wird. According to the invention, this object is achieved in that the accumulation of material in the profile parts that are decisive for increasing the static width by at least a preferably inserted strip of material is increased.

Die bevorzugte Ausführungsform der erfindungsgemässe Profilart begreift also wenigstens eine gesonderte Verstärkungseinlage, die durch den das Jewe-lig zu verstärkende Profilelement bildenden Streifenabschnitt ganz oder teilweise eingeschlossen wird Dadurch werden die für die Erhöhung der statischen Weite nicht massgeblichen Profilquerschnittsteie auf einer minimalen Wanddicke see halten unc im Vergleich zu herkömmlichen Kaltprofilen dickerer Wandstarke gleichwertige statische Eigenschaften erzielt. Understand the preferred embodiment of the type of profile according to the invention so at least one separate reinforcement insert, which the Jewe-lig to be reinforced profile element forming strip section included in whole or in part This means that the factors for increasing the static width are not relevant Profile cross-sectional steepness on a minimal wall thickness see unc in comparison Static properties equivalent to conventional cold profiles with thicker walls achieved.

Von der herstellungstechnischen Seite gesehen bietet die besagte AusFührungsform der erfindungsgemässen Kaltprofile den besonderen Vorteil, dass die durch ein Band gebildeten Verstarkungen während des üblichen oder nur geringfügig abgeänderten Profilierungsvorganges miteingearbeitet werden können. So werden beispielsweise bei der Herstellung eines an beiden Flanschen erfindungsgemäss verstärkten 1Profile die beiden von Vorratshaspeln abgezogenen Verstärkungsbänder während der Profilierung auf die später die Flanschinnenwände bildenden vorprofilierten Teile um die Einlagen herum zugefa-ltet und mit denselben durch Zusammenpressen in enge Anlage gebraucht. Seen from the manufacturing side, said Embodiment of the cold profiles according to the invention has the particular advantage that the reinforcements formed by a band during the usual or only slightly modified profiling process can be incorporated. For example at the production of a 1-profile reinforced at both flanges according to the invention the two reinforcement strips removed from supply reels during profiling on the pre-profiled parts around the inserts that will later form the flange inner walls folded around and used with the same by pressing them together in close contact.

Eine Alternative der bevorzugten Ausführungsform besteht darin, die zu verstärkenden Profil teile äus wenigstens dreifach zusammengefalteten Materiallagen zu bilden. Da aber für das mehrfache Zusammenfalten von Bandmaterial eine grössere zusätzliche Anzahl an Profilierungsstichen erfordert ist und für die grösseren Kaltprofile vielfach bereits eine nicht mehr in die üblichen Fertigungsanlagen hineinpassende Bandbreite notwendig ist, ist diese Ausführungsform der vorherbesagten herstellungstechnisch und demzufolge auch wirtschaftlich allerdings unterlegen. An alternative of the preferred embodiment is that to be reinforced profile parts äus at least three fold folded material layers to build. But there is a larger one for the multiple folding of tape material additional number of profiling stitches is required and for the larger cold profiles often one that no longer fits into the usual production systems Bandwidth is necessary, this embodiment is of the aforementioned manufacturing technology and consequently also economically inferior.

Die erfindungsgemässen mit Verstärkungsbereichen versehenen Profile kann man zusätzlich durch die an sich bekannte Massnahme des Wellens oder Sickens noch weiter versteifen. Dies kann durch Einwalzen, durch Einpressen oder bei der bevorzugten Ausführungsform durch Einlegen eines vorgewellten Bandes in ein entsprechend geformtes Vorprofil erfolgen. The profiles according to the invention provided with reinforcement areas you can also use the well-known measure of corrugation or beading stiffen even further. This can be done by rolling in, by pressing in or by preferred embodiment by inserting a pre-corrugated tape in a corresponding formed pre-profile.

Die erfindungsgemässe Profilausbildung ist bei I-, U-, C-, Z-, Winkel- und Spezial profilen, deren Querschnittsformen recht-oder schiefwinkelig, symmetrisch oder asymetrisch sind, anwendbar. The profile formation according to the invention is for I-, U-, C-, Z-, angle and special profiles with right-angled or oblique, symmetrical cross-sectional shapes or asymmetrical, are applicable.

Je nach Profilform und statischen Erfordernissen kann die Verstärkung an einem oder mehreren Profilquerschnittsteilen vorgesehen sein.Depending on the profile shape and static requirements, the reinforcement be provided on one or more profile cross-sectional parts.

Soweit Verstärkungseinlagen zum Einsatz kommen, können dieselben aus dem gleichen Material bestehen wie das zu profilierende Bandmaterial. Für letzteres kommen bekanntlich allgemein unlegierte und schwach legierte Stähle zur Anwendung. Es können auch hochlegierte Stahl sorten, sowie andere Metalle und deren Legierungen verwendet werden, sofern sie kaltverformbar und in Band- oder Blechform lieferbar sind. If reinforcement inserts are used, the same can be used consist of the same material as the strip material to be profiled. For the last one As is well known, unalloyed and weakly alloyed steels are generally used. High-alloy steels can also be used, as well as other metals and their alloys can be used if they are cold-deformable and available in strip or sheet form are.

Die Einlagen können aber auch aus einem Material anderer Beschaffenheit als das eigentliche Profilband sein. Dazu können sie eine andere Wandstärke aufweisen oder sogar aus mehreren übereinandergelegten Bändern bestehen. Die Wahl der Analyse und der Dimensionen der Einlagen kann also leicht in Funktion des zu erzielenden Verstärkungsgrades getroffen werden. However, the deposits can also be made of a material of a different nature than the actual profile band. For this purpose, they can have a different wall thickness or even consist of several superimposed bands. The choice of analysis and the dimensions of the deposits can thus easily be achieved as a function of the Reinforcement level can be taken.

Einige Ausführungsbeispiele von erfindungsgemässen Kaltprofilen sind in den Zeichnungen dargestellt und werden im folgenden näher erläutert. Es zeigt: Fig. 1 ein I-Profil mit zwei verstärkten Flanschen Fig. 2 ein Z-Profil mit einem verstärkten Flansch, und Fig. 3 ein U-Profil mit durch Dreifachfaitung verstärkten Schenkeln Bei dem in Fig. 1 dargestellfien I-Profil werden zwei Verstärkungsbänder 2 (z.B. 50 x 2,25 mm aus ST 37 Stahl) von den zu Flanschen geformten Endteilen eines profilierten Bandes 1 (z.B. Some exemplary embodiments of cold profiles according to the invention are shown in the drawings and will be explained in more detail below. It shows: 1 shows an I-profile with two reinforced flanges. FIG. 2 shows a Z-profile with one reinforced flange, and Fig. 3 a U-profile with reinforced by triple facings Legs In the I-profile shown in Fig. 1, two reinforcing strips are used 2 (e.g. 50 x 2.25 mm made of ST 37 steel) of the flanged end parts of a profiled band 1 (e.g.

340 x 2,25 mm aus ST 37 Stanl) in satter Anlage umschlossen.340 x 2.25 mm from ST 37 Stanl) enclosed in a lush enclosure.

Die Vorteile eines solchen verstärkten Profils ersieht man sofort aus dem Vergleich mit einem warmgewalzten I-100 Träger nach DIN 1025 und einem I-lO0 x 55 x 2,25 Kaltprofil mit doppeltgefalzten Flanschen. Bei dem I-100 Warm- und T -100 x 55 x 2,25 Normalkaltprofil sind die Hauptträgheits- und Wi derstandsmomente bei einem Metergewicht von 8,34 und 5,2 kg/m Jx 171 : Jy 12,2, Wx 34,2 : Wy 4,88 und Jx 121,5, Jy 11,2, Wx 24,3, Wy 4,0. Bei dem dargestellten erfindungsgemässen I-lO0 x 55 x 2,25 Profil mit 50 x 2,25 Profil mit 50 x 2,25 mm Einlagen in beiden Flanschen sind die Hauptträgheits- und Widerstandmomente bei einem Metergewicht von 6,9 kg/m, also einem gegenüber dem 1-100 Warmwalzträger um 17% leichteren Profil Jx 168,6, Jy 15,9, Wx 33,7, Wy 6,0, also gleichwertig mit den entsprechenden Werten des korrespondierenden Warmwal zträgers. The advantages of such a reinforced profile are immediately apparent from the comparison with a hot-rolled I-100 beam according to DIN 1025 and an I-100 x 55 x 2.25 cold profile with double folded flanges. With the I-100 Warm and T -100 x 55 x 2.25 normal cold profile are the main moments of inertia and resistance with weights per meter of 8.34 and 5.2 kg / m Jx 171: Jy 12.2, Wx 34.2: Wy 4.88 and Jx 121.5, Jy 11.2, Wx 24.3, Wy 4.0. In the illustrated according to the invention IO0 x 55 x 2.25 profile with 50 x 2.25 profile with 50 x 2.25 mm inserts in both Flanges are the main moments of inertia and drag for a meter weight of 6.9 kg / m, i.e. a profile 17% lighter than the 1-100 hot-rolled beam Jx 168.6, Jy 15.9, Wx 33.7, Wy 6.0, i.e. equivalent to the corresponding values of the corresponding hot rolled carrier.

Fig. 2 zeigt ein Z-Profil bei dem der obere Flansch erfindungsgemäss verstärkt ist und aus der Einlage 2, sowie dem dieselbe umgreifenden Endbereich des dünneren Bandmaterials 1 gebildet ist. Der untere Flansch ist in bekannter Weise durch einfaches Abkanten des Bandendbereiches bis zur Anlage mit sich selbst gebildet. Fig. 2 shows a Z-profile in which the upper flange according to the invention is reinforced and from the insert 2, as well as the same encompassing end area of the thinner strip material 1 is formed. The lower flange is in a known manner formed by simply folding the end of the belt up to the contact with itself.

In der Fig. 3 ist ein rechtwinkeliges, symmetrisches U-Profil dargestellt, das dadurch gekennzeichnet ist, dass die Schenkel durch dreimaliges Umbiegen um eine selbe Breite und anschliessendes Zusammenpressen hergestellt wurden. In der gezeigten Ausführung sind die Enstücke 3 zwischen den Schenkelaussenwänden eingeschlossen und die Verstärkung liegt aussen inBezug auf das U. Andere Faltungsmuster sind natürlich möglich. Genauso kann die Verstärkung innen in Bezug auf das U liegen. In Fig. 3 a right-angled, symmetrical U-profile is shown, which is characterized in that the legs are bent over three times the same width and then pressed together. In the The embodiment shown, the end pieces 3 are enclosed between the leg outer walls and the reinforcement is outside of the U. Other folding patterns are natural possible. Likewise, the reinforcement can be inside in relation to the U.
