Description

Gegenstand des Hauptpatentes 22 19 743 ist eine zweiteilige Stahlgurtung der im Obergriff des Anspruchs 1 angegebenen Gattung.The subject of the main patent 22 19 743 is a two-part steel belt in the preamble of the claim 1 specified genus.

Bei der Ausführung gemäß Hauptpatent sind die beiden die Stahlgurtung bildenden Profile als Walzprofile ausgebildet, die über eingeschweißte Verbindungsplatten miteinander verbunden sind. Diese Stahlgurtungen erfüllen alle an sie zu stellenden Anforderungen, jedoch ist ihre Herstellung verhältnismäßig teuer und sie weisen ein hohes Gewicht auf.In the design according to the main patent, the two profiles forming the steel chord are rolled profiles formed, which are connected to one another via welded connecting plates. These steel belts meet all the requirements to be placed on them, but their production is relatively expensive and they are very heavy.

Der Erfindung liegt daher die Aufgabe zu Grunde, die Herstellung einer derartigen Stahlgurtung zu verbilligen und die Montage zu vereinfachen.The invention is therefore based on the object of making the production of such a steel belt cheaper and to simplify assembly.

Gelöst wird die gestellte Aufgabe durch die im Kennzeichnungsteil des Anspruchs 1 angegebenen Merkmale. Es hat sich in der Praxis gezeigt, daß Blechprofile mit einer Stärke von etwa 4 mm den gestellten Anforderungen vollauf genügen. Wegen der gegenüber einem Walzträger verringerten Wandstärke macht sich für gleiche Belastungen eine etwas größere Schenkellänge erforderlich und es ist auch zweckmäßig, die Enden der Schenkel wieder in Stegrichtung abzukröpfen, so daß an Stelle des gemäß Hauptpatent vorgesehenen Profils ein gebogenes C-Profi! benutzt wird. Grundelement für die beiden Teile der Stahlgurtung ist danach ein kaltgewalztes Profil, das endlos lang aus Bandmaterial von der Rolle gefertigt werden kann. Bestimmte Normmengen können dabei automatisch während des Walzvorganges abgeschnitten werden,
ίο Durch die Erfindung ergibt sich etwa eine 40%ige Gewichtserleichterung, wobei der statische Wert Wx dennoch um 20% höher gehalten werden kann. Weiter wird es durch die Erfindung möglich, die Auflageleiste im parallelen Seitenwänden auszustatten, da die Schenkel der C-Profile ihrerseits U-förmig nach dem Innenraum abgewinkelt werden. Walztechnisch war bisher eine abgeschrägie Ausbildung dieser Auflagerleisten erforderlich.The problem posed is achieved by the features specified in the characterizing part of claim 1. It has been shown in practice that sheet metal profiles with a thickness of about 4 mm fully meet the requirements. Because of the reduced wall thickness compared to a rolled girder, a slightly larger leg length is required for the same loads and it is also useful to crimp the ends of the legs again in the direction of the web, so that instead of the profile provided according to the main patent, a curved C-profile! is used. The basic element for the two parts of the steel belt is then a cold-rolled profile that can be made of endless length from strip material from the roll. Certain standard quantities can be automatically cut off during the rolling process,
The invention results in a weight reduction of about 40%, with the static value W x still being able to be kept 20% higher. The invention also makes it possible to equip the support bar in parallel side walls, since the legs of the C-profiles are in turn angled in a U-shape towards the interior. In terms of rolling technology, a sloping design of these support strips was previously required.

Die Stahlgurtung gemäß vorliegender Erfindung ist ohne weiteres mit einer Stahlgurtung gemäß Hauptpatent kompatibel.The steel chord according to the present invention is readily available with a steel chord according to the main patent compatible.

Der Steg der C-Profile kann im Reich der neutralen Zone mit Löchern versehen werden, die eine weitere Gewichtsverminderung bringen, ohne die Festigkeitseigenschaften wesentlich zu beeinträchtigen.The web of the C-profiles can be provided with holes in the realm of the neutral zone, and a further Bring weight reduction without significantly impairing the strength properties.

Nachstehend wird ein Ausführungsbeispiel der Erfindung an Hand der Zeichnung beschrieben. In der Zeichnung zeigtAn exemplary embodiment of the invention is described below with reference to the drawing. In the Drawing shows

F i g. 1 eine Draufsicht einer erfindungsgemäß ausgebildeten zweiteiligen Stahlgurtung,F i g. 1 is a plan view of a device designed according to the invention two-part steel belt,

Fig.2 eine Seitenansicht der Stahlgurtung gemäß Fig.l,2 shows a side view of the steel chord according to Fig.l,

F i g. 3 eine Stirnansicht der Stahlgurtung nach F i g. 1 und 2,F i g. 3 shows an end view of the steel chord according to FIG. 1 and 2,

F i g. 4 eine Querschnittsansicht eines der C-förmigen Blechprofile in größerem Maßstab.F i g. 4 is a cross-sectional view of one of the C-shaped ones Sheet metal profiles on a larger scale.

Die Stahlgurtung besteht aus zwei aus Blech gebogenen bzw. gewalzten C-Profilen 12 und 14, die mit ihrem Steg 16 im Abstand zueinander angeordnet und durch eingeschweißte Abstandshalter 18 fest miteinander verbunden sind. Durch U-förmige Umbördelung des Blechstreifens am Fuß des einen Schenkels ergibt sich die nach innen in den Zwischenraum weisende Auflageleiste 26 (Nockenleiste) zur Abstützung der nicht dargestellten Widerlagerplatte. Die Höhe des Steges 16 ist gegenüber der Ausbildung gemäß Hauptpatent vergrößert und der Steg weist in der Mitte in einem vorbestimmten Registerabstand ausgestanzte sechseckige Löcher 20 auf. Die unteren Flansche sind mit runden ausgestanzten Löchern 22 versehen und diese Löcher ergeben eine Gewichtserleichterung und lassen vielfältige Befestigungen zu.The steel chord consists of two C-profiles 12 and 14, which are bent or rolled from sheet metal, with their web 16 arranged at a distance from one another and fixed to one another by welded spacers 18 are connected. The U-shaped flanging of the sheet metal strip at the foot of one leg results the inwardly facing support bar 26 (cam bar) to support the abutment plate not shown. The height of the web 16 is according to the training compared to Main patent enlarged and the bar has punched out in the middle at a predetermined register distance hexagonal holes 20. The lower flanges are provided with round punched holes 22 and these holes result in a weight reduction and allow a variety of attachments.
