Sicherheitsgewindebolzen zur Aufnahme in Zement, Stein oder ähnlichem MaterialThreaded safety bolt for insertion in cement, stone or similar material

Die vorliegende Erfindung betrifft einen Sicherheitsgewindebolzen, der an seinem im Gestein oder dergleichen eingespannten Ende kegelförmig ausgebildet ist, wobei Abschnitte des Kegels von Klemmschalen mit konischer Innenfläche umgeben sind, welche durch einen Ring zusammengehalten werden, der am unteren Ende der Klemmschalen sitzt und die Klemmschalen derart federnd angeordnet sind, dass sie gegen die Lochwand drücken, gemäss Hauptpatentanmeldung P 21 63 582.The present invention relates to a safety threaded bolt, which is conical at its end clamped in the rock or the like, with sections of the cone are surrounded by clamping shells with a conical inner surface, which are held together by a ring be, which sits at the lower end of the clamping shells and the clamping shells are arranged resiliently that they press against the perforated wall, according to the main patent application P 21 63 582.

In der vorausgehend genannten Anordnung werden die Klemm-In the above arrangement, the clamping

schalen durch eine winkelig gebogene Feder nach aussen gedrückt, die zwischen dem Sicherheitsgewindebolzen und den Klemmschalen liegt.shells outwards by an angled spring pressed, which lies between the safety threaded bolt and the clamping shells.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Unterbringung der Feder am Sicherheitsgewindebolzen baulich möglichst günstig zu gestalten, ohne dass hierzu ein gefräster Aufnahmeschlitz erforderlich ist, der in der bekannten Anordnung notwendig 1st, um eine freie Bewegung der Feder zu ermöglichen.The present invention is based on the object to make the accommodation of the spring on the safety threaded bolt structurally as favorable as possible without this a milled receiving slot is required, which is in the known arrangement is necessary to allow free movement of the spring.

Dies wird erfindungsgemäss dadurch erreicht, dass die Feder aus einem Gummielement besteht, welches in einer am unteren Ende des Gewindebolzens angeordneten Axialbohrung eingesetzt ist und welches mit seinem freiliegenden Ende zwischen zwei radial einwärts gerichteten, endseitigen, halbzylindrischen Vorsprüngen der Klemmschalen liegt.According to the invention, this is achieved in that the spring consists of a rubber element, which is in one at the bottom End of the threaded bolt arranged axial bore is used and which with its exposed end between two radially inwardly directed, end-side, semi-cylindrical projections of the clamping shells lies.

Durch diese Ausbildung wird es ferner möglich, die maximale Auslenkung der Klemmschalen nach aussen im unteren Teil der Lochwand zu erzielen, wodurch eine besonders günstige Verankerung des Gewindebolzens erreicht wird, so dass es nicht mehr erforderlich ist, die Klemmschalen an ihrer Aussenseite mit Nuten zu versehen.This training also makes it possible to achieve the maximum To achieve deflection of the clamping shells outwards in the lower part of the perforated wall, whereby a particularly favorable anchoring of the threaded bolt is achieved so that it does not it is more necessary to provide the clamping shells with grooves on their outside.

Darüberhinaus lässt sich als Folge der erfindungsgemässen Ausbildung auch die Anordnung des Federelements besonders leicht mittels selbsttätiger Anordnungen durchführen.In addition, as a result of the invention Training also carry out the arrangement of the spring element particularly easily by means of automatic arrangements.

Die Erfindung wird anschliessend an Hand eines in den Zeichnungen dargestellten Ausführungsbeispiels beschrieben. Es zeigen:The invention will then be described using an exemplary embodiment shown in the drawings. It demonstrate:

Der Sieherheitsgewindebolzen 1 weist einen oberen Gewindeabschnitt 2 auf, der zur Aufnahme einer Klemmmutter zur Befestigung eines Bauteils am Gewindebolzen bestimmt ist, sowie untere Kegelabschnitte 6, auf welchen die Klemmschalen angeordnet sind und die zur Aufnahme in Zement oder Gestein bestimmt sind. Der mittlere Teil des Gewindebolzens ist mit einem gerändelten Abschnitt 7 versehen, welcher noch von der Lochwand aufgenommen wird und diese nach oben abschliesst, so dass Klebemasse oder Zement, der die oberen Nuten 6 ausfüllen kann, nicht aus der Lochwand austritt·The security thread bolt 1 has an upper threaded portion 2, which is intended to receive a clamping nut for fastening a component on the threaded bolt, and also lower cone sections 6 on which the clamping shells are arranged and which are to be received in cement or rock are determined. The middle part of the threaded bolt is provided with a knurled section 7, which is still from the perforated wall is added and this closes off at the top, so that adhesive or cement that fill the upper grooves 6 cannot emerge from the perforated wall

Die beiden Klemmschalen J5 werden am Gewindebolzen durch einen Ring 12 gehalten. Beim Eintreiben des Gewindebolzens in ein Mauerloch oder dergleichen wird der Ring 12 hochgestreift. Dadurch können sich die unteren Enden der Klemmschalen 5 unter Einwirkung eines Gummielements 4 radial nach aussen gegen das Mauerloch bewegen. Das Gummielement 4 ist vorzugsweise zylindrisch ausgebildet und wird in einer endseitigen Axialbohrung 5 des Gewindebolzens aufgenommen. Solange sichThe two clamps J5 are attached to the threaded bolt by a Ring 12 held. When driving the threaded bolt into a hole in the wall or the like, the ring 12 is pulled up. As a result, the lower ends of the clamping shells 5 can move radially outwards under the action of a rubber element 4 move against the hole in the wall. The rubber element 4 is preferably cylindrical and is in an end Axial bore 5 of the threaded bolt was added. As long as

der Ring 12 in der in Fig. 1 dargestellten Lage befindet, wird das Gummielement zwischen zwei endseitigen Vorsprüngen 11 der beiden Klemmschalen zusammengedrückt, wie aus Pig. I und ersichtlich ist. Wird der Ring 12 nach oben gestreift, so werden durch die Elastizität des Gummielements die Klemmschalen nach aussen gedrückt und halten dadurch den Sicherheitsgewindebolzen in der Lochwand fest·the ring 12 is in the position shown in FIG. 1, the rubber element is pressed together between two end projections 11 of the two clamping shells, as from Pig. I and can be seen. If the ring 12 is slipped upwards, the clamping shells become due to the elasticity of the rubber element pressed outwards and thereby hold the threaded safety bolt in the perforated wall

Durch das Anziehen der auf dem Gewindebolzen 2 vorzusehenden Mutter wird der Gewindebolzen um einen geringen Betrag herausgezogen, wodurch die unteren Kegel 6, von denen mindestens einer innerhalb der Klemmschale zu liegen kommt, die Klemmschalen fest gegen das Mauerloch pressen. Durch die Anpressung der Klemmschalen wird sichergestellt, dass die Klemmschalen beim Anziehen des Bolzens nicht herausgezogen werden.By tightening the nut to be provided on the threaded bolt 2, the threaded bolt is reduced by a small amount pulled out, whereby the lower cone 6, of which at least one comes to lie within the clamping shell, press the clamps firmly against the hole in the wall. The pressing of the clamps ensures that the clamping shells are not pulled out when the bolt is tightened.

Im dargestellten Ausführungsbeispiel weist jede Klemmschale fünf konusförmig verlaufende Nuten auf. Es ist jedoch auch möglich, lediglich eine Nut vorzusehen oder aber die Klemmschalen derart zu verlängern, dass sie bis zum gerändelten Abschnitt 7 reichen.In the illustrated embodiment, each clamping shell has five conical grooves. It is however, it is also possible to provide only one groove or to extend the clamping shells in such a way that they are knurled Section 7 is sufficient.

Beim Anziehen des Gewindebolzens werden die Klemmschalen 5 in ihrem oberen Bereich unter der Einwirkung der Kegel 6 radial aufgeweitet. Um diese Aufweitung zu erleichtern, sind die Klemmschalen in ihrem oberen Bereich mit einer Schwächungsstelle 8 versehen, die als Längsnut ausgebildet ist.When the threaded bolt is tightened, the clamping shells 5 expanded radially in its upper area under the action of the cone 6. To facilitate this expansion, the Clamp shells provided in their upper area with a weakening point 8, which is designed as a longitudinal groove.

Als Folge der Ausbildung der konischen Nuten 9 in den Klemmschalen werden dort Schultern 10 ausgebildet, die an entsprechenden Schultern der Kegel 6 des Gewindebolzens anliegen. Die unterste Schulter der Klemmschale ist nahezu halbzylindrischAs a result of the formation of the conical grooves 9 in the clamping shells shoulders 10 are formed there, which bear against corresponding shoulders of the cones 6 of the threaded bolt. The lowest shoulder of the clamp is almost semi-cylindrical
