Abstract

The plastic dowel pin for screwing and unscrewing prefabricated concrete sections, and preferably concrete sleepers for railway track, has an outer thread (1) and an internal thread (2). The head of the dowel pin has no threading and is in the shape of a multi-sided hollow prism (3) inside, or outside, preferably hexagonal. The plastic dowel pin is rapidly screwed and unscrewed, mechanically. A section joined to the screwing spindle of the screwing mechanism is dropped into or onto the multi-sided prism, enabling the dowel pin to be turned. Before screwing in the dowel pin, it is inserted by hand into the threaded hole of the concrete section.

Description

Dübel aus Plaste, vorzugsweise für GleisbetonschwellenPlastic dowels, preferably for track concrete sleepers

Anwendungsgebiet der Erfindung Die Erfindung betrifft einen Dübel aus Plaste als Befestigungsmittel in Betonfertigteilen, vorzugsweise für Gleisbetonschwellen.Field of application of the invention The invention relates to a dowel Made of plastic as fasteners in precast concrete parts, preferably for track concrete sleepers.

Charakteristik der bekannten technischen Lösungen Es wurde bereits ein schraubbarer Dübel aus Plaste zum Auswechseln nach Verschleiß vorgeschlagen.Characteristic of the known technical solutions It has already been proposed a screwable plastic dowel for replacement after wear.

Das Ein- bzrv. Ausschrauben erfolgt vermittels einer Ahle mit mehreren Schneidfasen, die in den Dübel hineingeschlagen wird und durch deren Drohung der Schraubvorgang erfolgt.The one-bzrv. Unscrewing is done by means of an awl with several Cutting bevels that are driven into the dowel and threatened by the Screwing process takes place.

Das Lösen der in den Dübel gewissermaßen eingeschnittenen Ahle von dem Dübel ist nur unter Schwierigkeiten möglich.The loosening of the awl cut into the dowel from the dowel is only possible with difficulty.

Eine Lecnanisierung des Äuswechseliis.der Dübel ist mit dieser Verfahrensweise nicht möglich. Das beschriebene Verfahren ist dargelegt im Bericht r. 464 der Deutschen Reichsbahn, Versuchs- und.Entwicklungsstelle für den Oberbau, Brücken- und ltochbau.A lecnanization of the exchange of the dowels is possible with this procedure not possible. The procedure described is set out in report r. 464 of the Germans Reichsbahn, test and development center for the superstructure, bridge and tower construction.

Ziel der Erfindung Ziel der Erfindung ist es, den Zeit- und Arbeitskräfteaufwand bei dem Auswechseln der Dübel aus Plaste entscheidend zu verringern.AIM OF THE INVENTION The aim of the invention is to reduce the expenditure of time and manpower when replacing the plastic dowels.

Wesen der Erfindung Der Erfindung liegt die Aufgabe zugrunde, den Dübel aus Plaste 0 zu gestalten, das eine schnell lösbare Verbindung zwischen Dübel und Schraubwerkzeug mc;lich wird und damit eine.Mechanisierung des Ein- und Ausschraubens erfolgen kann. Weiterhin soll die Beschädigung des Dübels beim Einschrauben vermieden werden.Essence of the invention The invention is based on the object Make dowels out of plastic 0, which is a quick-release connection between Dowels and screwing tools are possible and thus a. Mechanization of the insertion and Unscrewing can be done. Furthermore, the damage to the anchor when screwing in be avoided.

Erfindungsgemäß wird das gewindelose Kopfteil des Dübels aus Plaste innen als mehrkantiges Hchlprisma, vorzugsweise Sechskanthohlprisma, beziehungsweise augen als Mehrkantprisma ausgebildet. Durch ein passendes Formstück, das mit der Spindel einer Schraubeinrichtung verbunden ist, wird eine formschlüssige Verbindung zwischen Dübel und Schraubeinrichtung hergestellt, die das mechanisierte Ein- und Ausschrauben ermöglicht.According to the invention, the threadless head part of the dowel is made of plastic inside as a polygonal Hchlprisma, preferably hexagonal hollow prism, respectively eyes designed as a polygonal prism. With a matching fitting that is connected to the The spindle of a screwing device is connected, is a form-fitting connection produced between dowel and screwing device, which the mechanized insertion and Unscrewing allows.

Ausführungsbeispiel Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden.Exemplary embodiment The invention is intended to be based on an exemplary embodiment are explained in more detail.

Die. zugehörige Zeichnung zeigt: Fig. 1: Seitenansicht des Dübels mit Mehrkanthohlprisma Fig. 2: Draufsicht des Dübels mit Mehrkanthohlprisma Fig. 3: Schnitt des Dübels mit Mehrkanthohlprisma Fig. 4: Draufsicht des Dübels mit Mehrkantprisma Der Dübel ist mit Außengewinde 1 und Innengewinde 2 versehen. Das gewindelose Kopfteil des Dübels ist innen als Mehrkanthohlprisma 3 bzw. außen als Mehrkantprisma 4 ausgebildet.The. The associated drawing shows: FIG. 1: side view of the anchor with polygonal hollow prism Fig. 2: Top view of the dowel with polygonal hollow prism Fig. 3: Section of the anchor with a polygonal hollow prism. Fig. 4: Top view of the anchor with a polygonal prism The dowel has an external thread 1 and an internal thread 2. The threadless headboard of the dowel is designed as a polygonal hollow prism 3 on the inside and as a polygonal prism 4 on the outside.

Das Auswechseln des Dübels geschieht mittels einer Schraubeinrichtung. Ein mit der Schraubspindel der Schraubeinrichtung verbundenes Formstück, das entsprechend der jeweiligen Dübelausführung ausgebildet ist, wird entweder in das Mehrkanthohlprisma 3 eingesonkt oder auf das Mehrkantprisma 4 abgesenkt. Die dadurch bewirkte formschlüssige Verbindung ermöglicht bei Drehung der Schraubspindel ein Ein- bzw, Ausschrauben des Dübels. Vor dem Einschrauben des Dübels wird dieser.von Hand in das Gewindeloch des RetonSertigteiles gesetzt.The dowel is replaced by means of a screw device. A fitting connected to the screw spindle of the screw device, the corresponding the respective dowel design is formed either in the polygonal hollow prism 3 sunk or lowered onto the polygonal prism 4. The resulting form-fitting Connection enables screwing in or screwing out when the screw spindle is turned of the dowel. Before screwing in the dowel, it is put into the threaded hole by hand of the finished part.
