Description:

Für bestimmte Zwecke, insbeßonder für La^er regale, sind warmgewalzte I-Träger als Konstruktionsmaterial wenig geeignet, v/eil sie im Verhältnir sum Verwendungszweck einerseits zu schwer, andererseits zu teuer sind. Man verwendet daher vorzugsweise aus Blechstreifen kaltgewalzte Profile, überwiegend U-Profile, die nachträglich verzinkt und/oder laufend gelocht sein können·For certain purposes, especially for storage racks, hot-rolled ones are used I-beams are not very suitable as a construction material, because they are too heavy in relation to the intended use on the one hand, and too expensive on the other are. It is therefore preferable to use cold-rolled strips of sheet metal Profiles, predominantly U-profiles, which are subsequently galvanized and / or can be continuously perforated

Diese U—Profile sind aber wenig verwindungssteif, so daß auch dort größere Profile verwendet werden müssen, wo hinsichtlich auf die Normalbelastung kleinere Profile genügen würben·However, these U-profiles are not very rigid, so that there too Larger profiles must be used where smaller profiles would be sufficient with regard to normal load

Es sind auch aus Blechstreifen kaltgewalzte I-Träger bekannt, deren Querschnitt symmetrisch zum Steg ist. Der nachstehend vorgeschlagenen Heuerung liegt nun die Erkenntnis zugrunde, daß ein I-Profil, welches uns;" netrisch zum Steg ist- besondere Vorteile hat.There are also known cold-rolled I-beams made of sheet metal strips Cross-section is symmetrical to the web. The one suggested below The hiring is based on the knowledge that an I-profile, which us; "netrical to the bridge is- has special advantages.

Daher wird vorgeschlagen, einen I-Träger aus Blechstreifen od. dgl. vorzugsweise aus '»'/armband stahl kalt so zu walzen, daß der Flansch an der einen Seite des Stegs die doppelte Blechstärke, an der anderen Seite nur die einfache Blechstärke hat, wobei die Flanschseite mit der einfachen Blechstärke breiter als die andere Flanschseite ist. Für bestimmte Zwecke kann es besonder¹- günstig sein, die verschiedenen Flanschseiten hinsichtlich ihrer Breite so aufeinander abzustimmen, daß die neutrale Faser des Trägers, die parallel zum Steg liegt, e^ durch diesen verläuft.It is therefore proposed to cold-roll an I-beam made of sheet metal strips or the like, preferably made of '»' / armband steel, so that the flange on one side of the web has twice the sheet thickness and on the other side only the single sheet thickness, whereby the flange side with the single sheet thickness is wider than the other flange side. For certain purposes, it may Customized ¹ - be advantageous to match the various flange sides in width to each other so that the neutral fiber of the carrier that lies parallel to the web, e ^ passes through this.

Eil solches Profil ist nicht nur einfacher zu walzen als die bisher bekannten Profile, sondern os ist bei gleichem \7id er st and smoment auch leichter als ein zum Steg symmetrisch gewalzter I-Träger, Gegenüber den U-Profilen, die der vorgeschlagene Träger vorzugsweise ersetzen soll, ist er torsionsstabiler.Such a profile is not only easier to roll than before known profiles, but os is at the same \ 7id he st and smoment too lighter than an I-beam rolled symmetrically to the web, compared to the U-profiles, which the proposed beam should preferably replace, it is more torsionally stable.

Claims

In the attached drawing is an example of execution. of such a proposed I-carrier: Eir. ', / armband is bent at right angles a at right angles to the same side at points 2 and 3, forming a web 1 / or ~ in sheet metal strips /. The bent parts 4 and 5 are opposite at 6 and 7 bent back 360 °, in such a way that the strips bent here go beyond the web 1 further than the distance from the dots 6 and 7 to the web 1 is. The proposed increase in price is not limited to this exemplary embodiment: the fl at ropes do not need to be on the same side but can also be bent alternately. For certain purposes, the strips of the flanges extending beyond the web 1 can also be shorter than the distance from the turning points 6 and 7 to the web 1; its length can in special cases also be zero. Protection claims:

1) I-beams, especially for storage racks, cold-rolled from sheet metal strips, preferably made of Ί7 bracelet st aiii, characterized by that üie flanges are rolled on one side to double the sheet thickness, on the other side to single sheet thickness.

2) I-beam nac; » Claim 1, characterized in that the width the flange sides with a single sheet metal thickness is dimensioned so that the Wu] line de3 moment of inertia of the profile cross-section through the duct of the web (1) runs.

3) I-beam according to claim 1 or 2, characterized in that the flanges, which are initially made with double sheet thickness, then call past the bridge (1) with single sheet thickness run in mirror image opposite at the two ends of the web (1).

4) I-beam according to any one of claims 1 or 3, characterized in that the _v Planseiiiilfte simple Blecli3tärke shorter than the

gate is thick.
