Description

Wanddübelhülse aus Faserstoff und Bindemittel Die Erfindung bezieht sich auf Wanddübelhülsen aus Faserstoff und Bindemittel zur Befestigung von Schrauben, Nägeln u. dgl.Wall dowel sleeve made of fiber and binder The invention relates on wall dowel sleeves made of fiber and binding agent for fastening screws, Nails and the like

Gemäß der Erfindung wird als Bindemittel ein in der Hitze koagulierter Eiweißstoff, z. B. koaguliertes Blutalbumin, verwendet. Bei der Herstellung der Hülsen setzt man dem Eiweißstoff zweckmäßig gepulvertes Harz oder gepulverten Schwefel o. dgl. Stoffe hinzu, die gegen Feuchtigkeit widerstandsfähig sind, nicht hygroskopisch sind und geeignet sind, eine Klebwirkung zwischen Dübelhülse und Lochwandung auszuüben. Die Hinzufügung von Glycerin oder Leinöl zu dem Eiweißstoff kann in manchen Fällen vorteilhaft sein, um der Dübelhülse eine gewisse Biegsamkeit zu verleihen.According to the invention, a heat-coagulated binder is used as the binder Protein, e.g. B. coagulated blood albumin is used. In making the Powdered resin or powdered sulfur is expediently placed in the protein o. The like. Add substances that are resistant to moisture, not hygroscopic are and are suitable for exerting an adhesive effect between the dowel sleeve and the wall of the hole. The addition of glycerin or linseed oil to the protein can in some cases be advantageous to give the dowel sleeve a certain flexibility.

Die neuen Wanddübelhülsen weisen den mit bituminösen Bindemitteln hergestellten Faserstoffdübeln gegenüber den Vorteil der größeren Festigkeit, Feuchtigkeitsbeständigkeit und Dehnungsfähigkeit und den mit Bindemitteln aus Gummi hergestellten Dübeln gegenüber den Vorteil der größeren Festigkeit und Lebensdauer auf.The new wall anchor sleeves have bituminous binders manufactured fiber dowels over the advantage of greater strength, moisture resistance and extensibility and the dowels made with rubber binders the advantage of greater strength and durability.
