Verfahren zum Bauen eines Brückenfelds; das auf zwei beabstandeten Auflagen ruht, dadurch gekennzeichnet, dass man im Voraus eine Vielzahl Längsbalkenelemente herstellt, die jeweils aus einem röhrenförmigen Kasten (10) mit Vieleckquerschnitt bestehen, der mindestens zwei ebene parallele Flächen hat, jeweils eine obere (11) und eine untere (12) Fläche, wobei die Kästen (10) ein Gewicht und eine Länge (L) haben, die mit den Hub- und Transportmöglichkeiten kompatibel sind, dass eine Vielzahl von Querbalken-Abstandshaltern (2), vorgefertigt werden, die jeweils aus einem Metallrohr (2) bestehen, das zwei einander gegenüber liegende Enden hat, dass man die Kästen (10) und Abstandshalter (2) auf die Baustelle bringt, wobei letztere mindestens zwei Auflagen (7) umfasst, die im Voraus hergestellt wurden, dass man die Kästen (10) Stoß an Stoß zusammenfügt, indem man ihre aneinander liegenden Enden fest verbindet, sodass man mindestens zwei Längsbalken (1, 1') bildet, die jeweils aus einer Reihe von Kästen (10) bestehen, dass man die so gebildeten Längsbalken so anbringt, dass sie über zwei Enden auf zwei beabstandeten Auflagen (7, 70) der Brücke ruhen, wobei die Längsbalken (1, 1') miteinander durch mindestens zwei Querbalken-Abstandshalter (2) fest verbunden werden, die jeweils durch zwei gegenüberliegende Enden (21) auf zwei Seitenflächen (13) gegenüber von zwei Kästen (10, 10') befestigt werden, die auf der gleichen Ebene auf den zwei Balken (1, 1') angeordnet sind, und dass man einen Belag (4) herstellt, der die Längsbalken bedeckt, von welchen mindestens ein Teil aus einer Vielzahl starrer Querverbindungselemente (3, 5) besteht, die auf die gesamte Länge des Felds verteilt sind und sich jedes mindestens über die Entfernung erstrecken, die die zwei Längsbalken (1, 1') trennt, wobei jedes Verbindungselement (3, 5) auf den oberen Flächen (11) der Längsbalken (1, 1') befestigt wird.
  19. Verfahren nach Anspruch 18, dadurch gekennzeichnet, dass die Verbindungselemente Metallprofile (3) sind, die jedes zwei Enden haben, die nach dem Verlegen auf den oberen Flächen (11) der zwei Längsbalken (1, 1') befestigt werden, wobei die Profile (3) regelmäßig über eine Entfernung beabstandet sind, die in etwa gleich der Breite eines Holzquerbalkens (40) des Typs Eisenbahnschwellen sind, und dass man einen Querbalken (40) in jeden Raum zwischen zwei Profile platziert, um einen vorläufigen Belag (4) zu bilden.
  20. Verfahren nach Anspruch 19, dadurch gekennzeichnet, dass man zum Ersetzen des vorläufigen Belags (4) durch einen endgültigen Belag die Querbalken (40) entfernt, dass man mindestens den Raum zwischen zwei Längsbalken mit an einander stoßenden Tafeln (31) bedeckt, die mit Verzahnungen versehen sind, die in die Verbindungsprofile (3) einklinken, und dass man eine Betonplatte (41) auf die aus den oberen Flächen (11) der Längsbalken (1, 1') mit den Tafeln (31) gebildete Fläche gießt, wobei letztere eine verlorene Schalung für das Gießen der Platte (41) bilden.
  21. Verfahren zur Herstellung eines Brückenfeldes nach Anspruch 18, dadurch gekennzeichnet, dass man im Voraus eine Vielzahl von Betonplattenelementen (5) herstellt, die jedes eine elementare Länge (I) haben und auf der Ebene jedes Längsbalkens (1, 1') mindestens eine Aussparung (6, 63) umfassen, die sich über die gesamte Höhe der Platte (5) so erstreckt, dass sie sich auf eine Zone (14) des Balkens (1) öffnet, die mit hervorstehenden Teilen, die Anschlüsse (61, 64, 65) bilden, versehen ist, und dass man nach dem Anbringen zweier Längsbalken (1, 1'), die mit Querbalken (2) verbunden sind, auf den oberen Flächen (11) der zwei Balken (1, 1') eine Reihe aneinander liegender Elementarplatten (5) so verlegt, dass die Aussparungen (6, 63) jeder Platte (5) mindestens eine Verbindungszone überdecken, die mit Anschlüssen (61, 64, 65) jedes Längsbalkens (1) versehen ist, und dass man anschließend einen Beton (16) in die Aussparungen (6, 63) so gießt, dass die feste Verbindung jedes Plattenelements (5) mit den zwei Längsbalken (1, 1') gewährleistet ist.
