Description

  

  Verfahren zur Erhöhung der mechanischen Festigkeit von Gegenständen  aus     elektrisch        isolierendem    Beton.    Die     mechanische    Festigkeit des sogenann  ten     Dielektrobetons,    eines durch besondere       Mischung    und     Behandlung        elektrisch.    isolie  rend gemachten Betons, lässt oft zu wünschen  übrig. Ähnlich wie beim gewöhnlichen Be  ton und Mörtel aus     Kies,    Sand, Zement und       Wasser    sind besonders die Zug- und     Biege-          festigkeit,des        Dielektrobetons    relativ gering;

    so dass     gewisse        Anwendungsgebiete    normaler  weise verschlossen bleiben. Zweck vorliegen  der Erfindung     ist    es, diesem Übelstande ab  zuhelfen und eine     Erhöhung    der mechani  schen Festigkeit von Gegenständen aus elek  trisch isolierendem Beton zu erreichen.  



       Erfindungsgemäss    erfolgt dies dadurch,  dass in den elektrisch isolierenden Beton  elektrisch isolierende Gebilde mit höherer me  chanischer Festigkeit als derjenigen des Be  tons eingebettet     werden.    Als Gebilde dieser  Art kommen Platten, Streifen oder Stäbe  sowie Kompositionen daraus aus gehärtetem  Glas oder aus     Kunststoffen    in Frage. Es  können aber auch Fasern, Geflechte oder  Gespinste aus Glas oder aus mineralischem  Fasermaterial natürlichen Ursprunges, z. B.

    Asbest, zur Anwendung     kommen.    Die elek  trischen, chemischen und thermischen Eigen  schaften des Werkstoffes des eingebetteten  Gebildes und speziell dessen Wärmedehnung       werden    zweckmässig so gewählt, dass diesel  ben den entsprechenden Eigenschaften des       Dielektrobetons,    in den sie     eingebettet    wer  den,     entsprechen        bezw.    nicht wesentlich von    denselben abweichen, und     daZ    ferner das       Einbringen    des Betons, dessen Behandlung  sowie     die        Anforderungen    an den fertigen Ge  genstand ohne Schaden ertragen werden.  



  Um die     mechanische    Zugfestigkeit des       eingebetteten        Gebildes    auch bei     grösserer          Ela        tizität        und        Dehnung    als der des     Dielektro-          betons    voll     auszunützen,    kann die     Einfügung     des     Gebildes    in vorgespanntem Zustande     er-          ,folgen.     



  Die     Einbettung    der Platten, Stäbe, Fa  sern, Gewebe oder     Gespinste    usw. kann auch  nur an solchen Stellen der Gegenstände aus       Dielektrobeton    erfolgen,. an denen starke  Zug- oder     Biegebeanspruchungen    auftreten,  und zwar in analoger Anordnung, wie die       Armierungseisen    in armiertem Beton ver  legt werden.  



  Der elektrisch isolierende Beton besteht  beispielsweise aus Zement,     Kies,    Sand,     Sili-          ziiundioxydsand    und Bitumen.  



  Zu     seiner    Herstellung kann einem Gemisch  von Zement, Kies, Sand und Wasser ein  Gemisch von     Siliziumdioxydsand    und Bitu  men zugesetzt werden. Das so erhaltene Ge  misch kann in Formen, in welchen die elek  trisch isolierenden Gebilde gegebenenfalls als       Armierungen    angeordnet sind, eingegossen  und erhärten gelassen werden.



  Process for increasing the mechanical strength of objects made of electrically insulating concrete. The mechanical strength of the so-called dielectric concrete, one electrical through special mixing and treatment. Insulating concrete often leaves a lot to be desired. Similar to ordinary concrete and mortar made from gravel, sand, cement and water, the tensile and flexural strength of dielectric concrete is relatively low;

    so that certain areas of application normally remain closed. The purpose of the present invention is to remedy this inconvenience and to achieve an increase in the mechanical strength of objects made of electrically insulating concrete.



       According to the invention, this takes place in that electrically insulating structures with a higher mechanical strength than that of the concrete are embedded in the electrically insulating concrete. As structures of this type, plates, strips or rods as well as compositions made of hardened glass or plastics come into question. But it can also fibers, braids or webs made of glass or mineral fiber material of natural origin, z. B.

    Asbestos, are used. The electrical, chemical and thermal properties of the material of the embedded structure and especially its thermal expansion are expediently chosen so that the same ben the corresponding properties of the dielectric concrete in which they are embedded correspond respectively. do not differ significantly from the same, and that the placing of the concrete, its treatment and the requirements for the finished object can be endured without damage.



  In order to fully utilize the mechanical tensile strength of the embedded structure even with greater elasticity and elongation than that of the dielectric concrete, the structure can be inserted in a pretensioned state.



  The embedding of the plates, rods, fibers, fabrics or webs, etc. can also only be done in such places of the objects made of dielectric concrete. where strong tensile or bending stresses occur, in an arrangement analogous to how the reinforcing bars are laid in reinforced concrete.



  The electrically insulating concrete consists for example of cement, gravel, sand, silicon dioxide sand and bitumen.



  For its production, a mixture of silicon dioxide sand and bitumen can be added to a mixture of cement, gravel, sand and water. The resulting mixture can be poured into molds in which the electrically insulating structures are optionally arranged as reinforcements and allowed to harden.
