Description
Schrankenbaum in Leichtbauweise für Eisenbahn- und Straßenschranken od. dgl. mit vorzugsweise elliptischem Querschnitt Die Erfindung betrifft einen Schrankenbaum in Leichtbauweise für Eisenbahn- und Straßenschranken od. dgl. mit vorzugsweise elliptischem Querschnitt.Lightweight barrier boom for rail and road barriers od. The like. With a preferably elliptical cross section The invention relates to a Barrier boom in lightweight construction for railroad and road barriers or the like. With preferably elliptical cross-section.
Allgemein wird angestrebt, die Schrankenbäume unter Beibehaltung der notwendigen Stabilität möglichst leichtgewichtig herzustellen, um beim Schrankenantrieb Energie und Kosten zu sparen.In general, the aim is to keep the barrier booms to produce the necessary stability as lightly as possible in order to drive the barrier Save energy and costs.
Es ist bereits ein solcher Schrankenbaum bekanntgeworden, der einen elliptischen Sperrholz-Hohlkörper aufweist, dessen Innenraum in Längsrichtung durch schottenartige Querwände unterteilt und durch Holme versteift ist. Dieser Schrankenbaum ist zwar relativ leicht, jedoch ist eine Herstellung verhältnismäßig aufwendig und kompliziert. Hinzu kommt noch, daß dieser Schrankenbaum durch Schlag oder Stoß mehr oder weniger großen Beschädigungen unterliegt.Such a barrier boom has already become known, the one Has elliptical plywood hollow body, the interior of which in the longitudinal direction through bulkhead-like transverse walls are divided and stiffened by spars. This barrier boom is relatively easy, but production is relatively expensive and complicated. In addition there is the fact that this barrier boom is more affected by blows or blows or is less subject to damage.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine einfachere konstruktive Ausbildung des Schrankenbaumes zu erzielen, mit der die aufgezeigten Mängel vermieden werden können. Erfindungsgemäß wird dies bei einem Schrankenbaum dadurch erreicht, daß er aus einem selbsttragenden Mantel besteht, der nach einem an sich bekannten Kunstharz-Gieß- und/oder -Wickelverfahren hergestellt ist und an seinem unverjüngten Ende eine seiner Befestigung dienende Blechmanschette aufnimmt. Der wesentliche Vorteil der Erfindung ist darin zu erblicken, daß er bei noch leichterem Gewicht und höherer Festigkeit wirtschaftlicher herzustellen ist. Darüber hinaus erübrigt sich fast jede Wartung, da dieser Schrankenbaum äußerst wetterfest ist.The invention is therefore based on the object of a simpler one to achieve constructive training of the barrier boom with which the indicated Defects can be avoided. According to the invention, this is the case with a barrier boom achieved in that it consists of a self-supporting coat, which after a known synthetic resin casting and / or winding process is produced and receives at its untapered end one of its fastening serving sheet metal sleeve. The main advantage of the invention can be seen in the fact that it is even lighter Weight and higher strength is more economical to produce. Furthermore Almost any maintenance is unnecessary as this boom is extremely weatherproof.
Nachfolgend sei der Erfindungsgegenstand beispielsweise beschrieben: Der Schrankenbaum stellt einen Hohlkörper dar, der insbesondere für Halbschrankenanlagen aus einem Stück gefertigt ist, d. h., der Mantel ist selbsttragend und benötigt keine inwendigen Versteifungen u. dgl. Die Fertigung dieses Baumes erfolgt nach einem kunststoffverarbeitenden Verfahren, z. B. einem Kunstharz-Gießverfahren, zur Herstellung verjüngt auslaufender Hohlkörper, bei dem ein trockener oder vorgetränkter Füllstoff in einer oder mehreren Lagen auf einen Kern aufgebracht wird. Darüber wird dann eine der äußeren Form des herzustellenden Hohlkörpers entsprechende flüssigkeitsundurchlässige Hülle gezogen und das Volumen zwischen Kern und Hülle mit einem flüssigen, aushärtbaren Kunststoff ausgegossen und zur Verfestigung gebracht. An dem unverjüngten Ende des Schrankenbaumes wird eine seiner Befestigung dienende Blechmanschette mit eingegossen. In an sich bekannter Weise kann dem Gießharz bereits eine Signalfarbe beigemischt werden. Eine andere Möglichkeit der Farbgebung besteht darin, eine die Signalfarbe tragende Einlage mit einzugießen, wobei das zur Verwendung gelangende Kunstharz durchscheinend sein muß. Hat nun die Einlage ebenfalls die Eigenschaft durchscheinend zu sein, so kann der Schrankenbaum von innen her in bekannter Weise mit einer Dauer-oder Blinklichtanlage versehen werden. Bei Vollschranken dürfte es vorteilhafter sein, den Schrankenbaum aus mehreren Stücken herzustellen und diese dann in geeigneter Weise formschlüssig zu verbinden.The subject matter of the invention is described below, for example: The barrier boom is a hollow body, which is particularly suitable for half-barrier systems is made in one piece, d. i.e., the coat is self-supporting and required no internal stiffeners and the like. The production of this tree takes place after a plastics processing process, e.g. B. a synthetic resin casting process, for Manufacture of tapered hollow bodies, in which a dry or pre-soaked Filler is applied to a core in one or more layers. About that Then one of the outer shape of the hollow body to be produced corresponding liquid-impermeable Shell pulled and the volume between core and shell with a liquid, curable Plastic poured out and solidified. At the untapered end of the A sheet metal sleeve serving to fasten it is cast in with the barrier boom. In a manner known per se, a signal color can already be added to the casting resin will. Another possibility of coloring is to use the signal color The load-bearing insert is to be poured in, the synthetic resin used must be translucent. The inlay now also has the property of being translucent to be, the barrier boom can be from the inside in a known manner with a permanent or Flashing lights are provided. In the case of full barriers, it should be more advantageous to make the barrier boom from several pieces and then in suitable Way to connect positively.
