Abstract

Die vorliegende Erfindung betrifft einen Gitterträger (1) für Bewehrung und Ausbau im Tunnel-, Berg- und Schachtbau sowie für den konstruktiven Stahlbau oder dergleichen, mit mindestens drei Gurtstäben (2,3,4,5), von denen wenigstens zwei (2,5;3,4) als Obergurt (6) oder Untergurt (7) ausgebildet sind, und die Gurtstäbe (2 bis 5) miteinander verbindenden Aussteifungselementen (10), wobei der Abstand (11) zwischen den wenigstens zwei als Obergurt oder Untergurt ausgebildeten Gurtstäben etwa dem Querschnitt (12) der Aussteifungselemente entspricht und die Aussteifungselemente in der durch den Abstand festgelegten Ebene (13) zwischen den wenigstens zwei Gurtstäben, diese miteinander verbindend, angeordnet sind.
