Description
Seit einigen Jahren werden Stahlmasten für Hochspannungs leitungen angesägt und beschädigt, so daß diese sogar umkippen. Um diesen Sabotageakten entgegenzuwirken, unterhalten die verantwortlichen Firmen und Behörden unzählige Aufsichtsbe amte, um Tag und Nacht derartige Schäden zu vermeiden.Steel poles have been used for high voltage for several years Sawed and damaged lines, so that they even tip over. To counteract these acts of sabotage, the entertain responsible companies and authorities countless supervisory boards office to avoid such damage day and night.
Es wurde bislang so verfahren, daß die vier tragenden Ständer der Masten mit einer 20 cm dicken Betonschicht ummantelt wurden. Dieses Verfahren ist sehr schwierig und aufwendig, zumal die Masten oft in schwer befahrbarem Gelände stehen. Um Transportkosten zu sparen, hat man versucht, festere Materialien einzusetzen, wodurch die Ummantelung dünner sein kann. Hier gibt es Nachteile, da das Anschneiden noch nicht völlig verhindert werden kann. Auch der Brandschutz ist noch nicht gewährleistet.So far it has been done that the four supporting stands the masts are covered with a 20 cm thick layer of concrete were. This process is very difficult and time-consuming especially since the masts are often in difficult-to-drive terrain. In order to save transport costs, attempts have been made to make them firmer Use materials, which makes the jacket thinner can be. There are disadvantages here, since the cutting is still cannot be completely prevented. Fire protection too is not yet guaranteed.
Durch die europäische Offenlegungsschrift 01 08 553 ist es bekannt, einen Gitterstab zum Schutz gegen Zerstörung mit einem Mörtel aus polymeren oder hydraulischem Material und Silicium-Karbid zu ummanteln.Through the European patent application 01 08 553 it is known to use a lattice bar to protect against destruction with a mortar made of polymeric or hydraulic material and to coat silicon carbide.
Der Erfindung liegt die Aufgabe zugrunde, eine Ummantelung zu schaffen, welche ein Beschädigen der Hochspannungsmasten erschwert.The invention has for its object a casing to create which is damaging the high voltage pylons difficult.
Diese Aufgabe wird dadurch gelöst, daß die Ummantelung aus einem Gemisch aus Epoxidharz, Härter, Zement, Sand und Silicium-Karbid-Granulat besteht.This object is achieved in that the casing from a mixture of epoxy resin, hardener, cement, sand and silicon carbide granules.
Die Masten, die auf vier aus Stahl bestehenden Winkeleisen stehen, werden bis zu einer Höhe von 5-8 Metern ummantelt. Diese Ummantelung der Stahlständer soll ein Anbrennen und ein Anschneiden des Stahlständers verhindert.The masts, which are based on four steel angle irons are encased up to a height of 5-8 meters. This coating of the steel stand is intended to burn and prevents the steel stand from being cut.
Es ist vorteilhaft, wenn das Verhältnis des Silicium-Karbids zum Sand mindestens 60% beträgt. Damit ist die Feuerfestigkeit gegeben. Ferner wird durch diesen Mörtel ein Anschneiden des Schutzmantels unmöglich gemacht.It is advantageous if the ratio of silicon carbide to the sand is at least 60%. So that is fire resistance given. Furthermore, this mortar is used for cutting of the protective jacket made impossible.
Mit diesem Mörtel werden die vier tragenden Stahlständer in eine Schichtstärke von mindestens 1 cm ummantelt. Man kann, um die Schichtdicke zu erhöhen, noch schnittfeste Preßklinker oder Fliesen mit in diese Schicht einbauen.The four load-bearing steel stands are made with this mortar encased in a layer thickness of at least 1 cm. Man can be cut-resistant to increase the layer thickness Install press clinker or tiles in this layer.
Durch diese Ummantelung sind die Masten günstig in bezug auf Materialkosten und den Materialtransport mit optimalen Ergebnis geschützt.Thanks to this sheathing, the masts are inexpensive on material costs and material transport with optimal Result protected.
