Abstract

Die Erfindung betrifft einen Gitterträger für den Ausbau tunnelförmiger Bauwerke, welcher an seinen Enden angeordnete Koppelelemente (4c) aufweist. Der Gitterträger umfasst sich in seiner Längsrichtung erstreckende sowie in seinem Querschnitt die Eckpunkte eines Dreiecks zueinander bildende zwei Untergurte (5a, 5b) und einen Obergurt (6). Die zwei Untergurte (5a, 5b) sind über eine Fachwerkanordnung aus einzelnen Streben mit dem Obergurt (6) verbunden. Erfindungsgemäß umfassen die Koppelelemente (4c) an jedem der beiden Enden zwei Blechstreifen (13c), welche sich jeweils von dem Obergurt (6) zu einem der Untergurte (5a, 5b) erstrecken. Um mehrere Gitterträger miteinander zu verbinden, besitzen die Blechstreifen (13c) endseitig angeordnete Schlaufen (14c), welche zur Aufnahme von entsprechenden Verbindungsmitteln dienen.

The invention relates to a lattice girder for the expansion tunnel-shaped structures, which has arranged at its ends coupling elements (4c). The lattice girder comprises two lower girders (5a, 5b) extending in its longitudinal direction and, in its cross section, the corner points of a triangle forming one another, and a top flange (6). The two lower straps (5a, 5b) are connected via a framework arrangement of individual struts with the upper flange (6). According to the invention, the coupling elements (4c) comprise at each of the two ends two sheet-metal strips (13c) which each extend from the top flange (6) to one of the bottom straps (5a, 5b). In order to connect a plurality of lattice girders with each other, the sheet metal strips (13c) end loops (14c), which serve to receive corresponding connection means.
