Claims (6)

  1. Tragbalken (1) aus Beton, versehen mit einer im Beton (11) vorhandenen Bewehrung (3), die einer Anzahl paralleler, in Längsrichtung des Tragbalkens verlaufender Stäbe (5) umfasst, sowie einem ersten längliches Bewehrungselement, das spiralförmig um diese Stäbe (5) gewickelt und an diesen Stäben befestigt ist, wobei das Bewehrungselement einen durchgehenden Strang (7) aus flexiblem Fasermaterial und ein die Fasern des Materials verbindendes Bindemittel umfasst, wobei die Bewehrung (3) ein zweites längliches Bewehrungselement umfasst, das ebenfalls einem kontinuierlichen Strang (7) aus flexiblem Fasermaterial umfasst und einem Bindemittel das die Fasern des Materials miteinander verbindet und das spiralförmig um die Stäbe (5) gewickelt ist, jedoch in der entgegengesetzten Richtung zur ersten Bewehrungselement, welches zweite Bewehrungselement ebenfalls an den Stäben und darüber hinaus an den Kreuzungsstellen der beiden Bewehrungselemente an dem ersten Bewehrungselement befestigt ist, dadurch gekennzeichnet, dass der Beton hochfester Beton ist und das Fasermaterial hauptsächlich aus Basaltfasern besteht, und der Tragbalken (1) einem im Gebrauch auf Zug belasteten untere Teil (1A) und einem im Gebrauch auf Druck belasteten obere Teil (1B) umfasst, wobei der Querschnitt des untere Teil (1A) kleiner ist als der Querschnitt des obere Teil (1B), wobei der untere Teil (1A) des Tragbalkens (1) und der untere Teil der Verstärkung (3) eine sich vom oberen Teil (1B) des Tragbalkens verjüngende Form haben, und wobei mehr als ein Stab (5) sich im schmalen unteren Ende befindet.
  2. Tragbalken nach Anspruch 1, dadurch gekennzeichnet, dass das Bindemittel durch keramischen Kleber gebildet ist.
  3. Tragbalken nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die Basaltfasern zum Zusammenhalten von einem spiralförmig um die Basaltfasern gewickelten Draht umgeben sind.
  4. Tragbalken nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass an jedem Punkt (13, 15) der Berührung zwischen den Strängen (7, 9) und den Stäben (5) die Strängen an den Stäben befestigt sind.
  5. Tragbalken nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass der untere Teil (1B) des Tragbalkens (1) einen etwa trapezförmigen Querschnitt aufweist.
  6. Tragbalken nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass der obere Teil (1B) des Tragbalkens (1) einen rechteckigen oder nahezu rechteckigen Querschnitt aufweist.
