Description

Die Erfindung bezieht sich auf eine Schraubensicherung für U- und I-Träger. Bei Verschraubungen an U- und I-Trägern muß außer einer Vierkantscheibe mit einer Neigung der Anlageflächen von 8 oder 14°/o nach DIN 434 und 435 zur Sicherung der Schraubverbindung ein Federring untergelegt oder die Schraube durch einen Splint gesichert werden. Um den Federring oder den Splint zu vermeiden, ist gemäß der Erfindung eine Schraubensicherung für U- und I-Träger so ausgebildet, daß eine Vierkantscheibe für U- und I-Träger mit einer Neigung der Anlageflächen von 8 oder 14% aus Federstahl hergestellt und an einer beliebigen Stelle aufgeschlitzt ist und daß die Enden an dieser Stelle aufgebogen sind. Ferner wird die Vierkantscheibe ballig ausgeführt. Durch diese Formgebung wird die Federkraft gleichmäßig verteilt und eine Biegebeanspruchung des Schraubenbolzens vermieden.The invention relates to a screw locking device for U- and I-beams. In the case of screw connections on U- and I-beams, in addition to a square washer with an inclination of the contact surfaces of 8 or 14 ° / o according to DIN 434 and 435, a spring washer must be placed underneath to secure the screw connection or the screw must be secured with a split pin. In order to avoid the spring ring or the split pin, a screw locking device for U- and I-beams is designed according to the invention so that a square washer for U- and I-beams is made of spring steel with an inclination of the contact surfaces of 8 or 14% is slit at any point and that the ends are bent up at this point. In addition, the square washer is crowned. This shape distributes the spring force evenly and avoids bending stress on the screw bolt.

Schraubensicherungen aus Federstahl in der Form balliger, an einer Stelle aufgeschlitzter Vierkantscheiben sind an sich bekannt, jedoch ist die Stärke dieser Scheiben über ihre ganze Fläche konstant, weshalb sie zur Verwendung an den schrägen Auflageflächen der U- und I-Träger nicht geeignet sind.Thread locks made of spring steel in the form of spherical square washers slit open at one point are known per se, but the thickness of these washers is constant over their entire surface, which is why they are not suitable for use on the inclined contact surfaces of the U- and I-beams.

Abb. i zeigt eine Schraubensicherung in der Form einer Balligen, geschlitzten Vierkantscheibe mit aufgebogenen Enden; Abb. a zeigt eine Seitenansicht und Abb. 3 eine Draufsicht.Fig. I shows a screw locking device in the form of a convex, slotted Square washer with bent ends; Fig.a shows a side view and Fig. 3 is a plan view.
