Description

Diese Erfindung betrifft einen Dübelhalter aus Elastomer oder Kunststoff.This invention relates to an anchor holder made of elastomer or plastic.

Beim Herstellen von Eisenbahnschwellen müssen für den Einbau von Dübeln sogenannte Dübelhalter verwendet werden. Der Dübelhalter, z.B. aus einem Elastomer gefertigt, wird im Boden der Schalung für die Schwellen mit Hilfe einer Schraube befestigt. Die Schraube wird nach dem derzeitigen Stand sehr aufwendig gefertigt. Sie besitzt einen speziellen Schraubenkopf, mit dem sie in eine Elastomermatrix mit einem Haftmittel einvulkanisiert wird. Diese Art von Schrauben ist sehr teuer und die Herstellung des Dübelhalters ist kompliziert.When manufacturing railway sleepers, so-called dowel holders must be used for the installation of dowels. The dowel holder, e.g. Made of an elastomer, is fastened in the bottom of the formwork for the sleepers with the help of a screw. The screw is currently manufactured very complex. It has a special screw head with which it is vulcanized into an elastomer matrix with an adhesive. This type of screw is very expensive and the manufacture of the dowel holder is complicated.

Die vorliegende Erfindung hat sich zur Aufgabe gestellt, einen Dübelhalter aus Elastomer oder Kunststoff zu schaffen, welcher mit einer einfachen Befestigungsschraube versehen ist.The present invention has for its object to provide a dowel holder made of elastomer or plastic, which is provided with a simple fastening screw.

Erfindungsgemäß wird dies dadurch erreicht, daß mit einer Befestigungsschraube im Dübelhalter mit dem Verbindungselement, das die Form eines Kunststoffkorbes besitzt, die Elastomer- oder Kunststoffmasse des Dübelhalters in den Hohlräumen des Kunststoffkorbes verankert ist.According to the invention this is achieved in that the elastomer or plastic mass of the dowel holder is anchored in the cavities of the plastic basket with a fastening screw in the dowel holder with the connecting element, which has the shape of a plastic basket.

Für den Dübelhalter nach dieser Erfindung kann man am Markt erhältliche vier-, sechs- oder achtkantige Schrauben verwenden. Das bedeutet eine vielfache Verbilligung des Dübelhalters. Die Herstellung des Dübelhalters mit Hilfe des Kunststoffkorbes ist einfach und unkompliziert. Man benötigt kein Haftmittel. Die Kunststoff- oder Elastomermasse vom Dübelhalter verankert sich in den Seitenöffnungen des Kunststoffkorbes und füllt die Hohlräume zur Gänze aus. Die Befestigungsschraube ist somit mit dem Dübelhalter fest verbunden und es kommt auch nach mehrmaliger Verwendung des Dübelhalters zu keiner Zerstörung der Verbindung zwischen Dübelhalter und Schraube.For the dowel holder according to this invention, one can use four, six or eight-sided screws available on the market. This means a multiple reduction in the price of the dowel holder. The production of the dowel holder with the help of the plastic basket is simple and uncomplicated. No adhesive is required. The plastic or elastomer mass from the dowel holder is anchored in the side openings of the plastic basket and completely fills the cavities. The fastening screw is thus firmly connected to the dowel holder and there is no destruction of the connection between dowel holder and screw even after repeated use of the dowel holder.

Den Kunststoffkorb kann man im Spritzgießverfahren aus einem Kunststoff in einem Arbeitsvorgang einfach herstellen. Ein Ausführungsbeispiel der Erfindung ist nachfolgend anhand der Zeichnung näher erläutert.The plastic basket can be easily manufactured from plastic in one operation. An embodiment of the invention is explained below with reference to the drawing.

In Fig. 1 ist der Kunststoffkorb im Grundriß, in Fig. 2 im Aufriß und in Fig. 3 in Ansicht von unten dargestellt. Dieser Verbindungskorb ist für eine sechskantige Befestigungsschraube geeignet. In Fig. 4 ist der Dübelhalter mit der Befestigungsschraube im Aufriß dargestellt. In Fig. 5 und Fig. 6 sind weitere Varianten des Kunststoffkorbes dargestellt. Der Kunststoffkorb ist in dieser Ausführung in Form eines sechseckigen Prismas gestaltet. Der Maßstab der Zeichnungen ist 2 : 1.In Fig. 1 the plastic basket is shown in plan, in Fig. 2 in elevation and in Fig. 3 in bottom view. This connection basket is suitable for a hexagonal fastening screw. In Fig. 4 the dowel holder with the fastening screw is shown in elevation. 5 and 6 show further variants of the plastic basket. The plastic basket is designed in the form of a hexagonal prism. The scale of the drawings is 2: 1.

In Fig. 1 ist der Kunststoffkorb 1 im Grundriß dargestellt, wobei die Verbindungsstege 2 die einzelnen Säulen 4 verbinden. Am Boden des Prismas befindet sich der Ring 7 mit Schraubenbohrung 6 und Schraubenauflagefläche 5.In Fig. 1 the plastic basket 1 is shown in plan, the connecting webs 2 connecting the individual columns 4. At the bottom of the prism is the ring 7 with screw hole 6 and screw contact surface 5.

In Fig. 2 ist der Kunststoffkorb im Aufriß dargestellt, wobei die Säulen 4 und Verbindungsstege 2 bogenförmige Seitenöffnungen 3 bilden. In den Seitenöffnungen 3 ist der Ring 7 mit Schraubenauflagefläche 5 sichtbar.In Fig. 2 the plastic basket is shown in elevation, the columns 4 and connecting webs 2 forming arcuate side openings 3. In the side openings 3, the ring 7 with the screw contact surface 5 is visible.

In Fig. 3 ist der Kunststoffkorb 1 in der Ansicht von unten dargestellt, wobei die Säulen 4 mit dem Ring 7 verbunden sind. Die Säulen 4 sind in diesem Falle als Ecksäulen in den Ecken des Sechskantprismas plaziert.In Fig. 3 the plastic basket 1 is shown in a view from below, the columns 4 being connected to the ring 7. The columns 4 are in this case placed as corner columns in the corners of the hexagonal prism.

In Fig. 4 ist der Dübelhalter 9 mit der eingebauten Befestigungsschraube 8 dargestellt. Der Kunststoffkorb 1 ist im Teilausschnitt sichtbar.4 shows the dowel holder 9 with the built-in fastening screw 8. The plastic basket 1 is visible in the partial section.

In Fig. 5 ist im Grundriß und Schnitt A-A der Kunststoffkorb 1 dargestellt. Die Säulen 4 sind an den Längsseiten der Verbindungsstege 2 plaziert.In Fig. 5, the plastic basket 1 is shown in plan and section AA. The columns 4 are placed on the long sides of the connecting webs 2.

In Fig. 6 ist der Kunststoffkorb 1 im Aufriß und Schnitt B-B zu sehen, wobei durch die Seitenöffnungen 3 der Ring 7 mit der Schraubenauflage 5 und Verbindungsstege 2 ersichtlich sind.6, the plastic basket 1 can be seen in elevation and section B-B, the ring 7 with the screw support 5 and connecting webs 2 being visible through the side openings 3.

Die Säulen 4 sind in allen Fällen so angebracht, daß es zu keinem Überdrehen der Befestigungsschrauben kommen kann. Selbstverständlich muß der Kunststoffkorb 1 einer z.B. vier- oder achtkantigen Befestigungsschraube angepaßt werden.The columns 4 are attached in all cases so that the fastening screws cannot be overtightened. Of course, the plastic basket 1 must e.g. four or eight-sided fastening screw can be adjusted.

Für die Herstellung des Kunststoffkorbes 1 kann ein Kunststoff mit Shore D größer als 20, z.B. Polyamid 6, Polypropylen usw. verwendet werden. Der Dübelhalter kann aus einem Elastomer oder Kunststoff, z.B. Polyurethan ca. 60 Shore A, hergestellt werden.For the production of the plastic basket 1, a plastic with Shore D greater than 20, e.g. Polyamide 6, polypropylene, etc. can be used. The dowel holder can be made of an elastomer or plastic, e.g. Polyurethane approx. 60 Shore A.
