Abstract

The anchor is for mounting in a drill hole in reinforced concrete and it consists of a longitudinally slotted expanding sleeve, and an expanding body, which during insertion of the sleeve, engages into its slot with a wedge-shaped part. The expanding body consists of sheet metal, with its wedge-shaped part being corrugated. The pitch of the corrugation increases towards the insertion end. The expanding body also has a stop, to limit its depth of penetration. The stop (6) is extended in radial direction; it bears against the face of the concrete wall and is rolled-in to form a sleeve, with an internal thread. The front face of the stop section, forming the sleeve, is staggered in relation to the front face forming the stop surface.

Gleichzeitig mit dem Ausprägen des in die Längsschlitzung der Spreizhülse eingreifenden Teil des Spreizkörpers erfolgt vorteilhafterweise auch die Herstellung des Gewindes durch Einprägen der Gewindegänge. Durch die erfindungsgemäße Ausgestaltung sind somit auch bei einem Schlagspreizdübel, dessen Spreizkörper die Möglichkeit des Eindrehens einer Befestigungsschraube bietet, die Vorteile des Hauptpatentes erreicht.Fastening screws, hook screws, Studs and the like. Be screwed in for fastening objects. Simultaneously with the expression of the engaging in the longitudinal slot of the expansion sleeve Part of the expansion body is advantageously also used to produce the thread by embossing the threads. The design according to the invention are thus also with a blow-in expansion anchor, the expansion body of which the possibility of Screwing in a fastening screw offers the advantages of the main patent.

Nach einer weiteren Ausgestaltung der Erfindung kann die Stirnseite des zur Bildung der Hülse verwendeten Teiles des Anschlages gegenüber der die Anschlagfläche bildenden Stirnseite abgesetzt sein. Diese Ausgestaltung verhindert, daß die eingerollte Hülse beim Einschlagen des Schlagspreizdübels der Belastung des Anschlages ausgesetzt ist, die insbesondere bei unebener Oberfläche des Mauerwerkes zu einer Verschiebung der Hülse und damit zu einer Versetzung der Gewindegänge führen könnte. Die Versetzung der Gewindegänge würde dann das Eindrehen einer Befestigungsschraube unmöglich machen.According to a further embodiment of the invention, the end face of the part of the stop used to form the sleeve opposite that of the stop surface be offset forming face. This design prevents the curled Sleeve when hammering in the impact expansion anchor the load of the Stop is exposed, especially with an uneven surface of the masonry lead to a displacement of the sleeve and thus to an offset of the threads could. The offset of the thread turns would then require screwing in a fastening screw to make impossible.
