(FR) SYSTÈME D'ARMATURE POUR LA CONSTRUCTION EN BÉTON DE LA COQUE INTÉRIEURE D'UN OUVRAGE DE TUNNEL
Abstract
(DE)
Die Erfindung betrifft ein selbsttragendes Bewehrungssystem für den Betonausbau der Innenschale eines Tunnelgebäudes. Es ist die Aufgabe der Erfindung, die Außenschale (15) oder Gebirgswand eines Tunnelgebäudes abzustützen. Erreicht wird dies nach der Erfindung durch Spannbögen (4) oder Spannringes, gebildet aus einem oder mehreren Bogensegmenten (23, 24) aus einzelnen Bewehrungsstahlstäben, M-förmigen Spannstützkörpern(2) mit einem Verbindungsbereich zu den Spannbögen sowie Stützarmen zur abstützenden und den Abstand zu einer Außenschale (15) oder der Gebirgswand herstellenden Verspannung des Bogens und Abstandhaltern an den Spannstützkörpern (2) und zwischen der Außenlage (19) und einer Innenlage (20) der Bewehrung.
(EN)
The invention relates to a self-supporting reinforcement system for the concrete lining of the inner shell of a tunnel construction. The object of the invention is that of supporting the outer shell (15) or rock wall of a tunnel construction. According to the invention, this is achieved by tension brackets (4) or tension rings, formed from one or more bracket segments (23, 24) made of individual reinforcing steel bars, M-shaped tensioning support bodies (2) having a connecting region to the tension brackets, and support arms for the supporting bracing, establishing the spacing with respect to an outer shell (15) or rock wall, of the bracket and spacers on the tensioning support bodies (2) and between the outer layer (19) and an inner layer (20) of the reinforcement.
(FR)
L'invention concerne un système d'armature autoporteur pour la construction en béton de la coque intérieure d'un ouvrage de tunnel. L'invention vise à soutenir la coque extérieure (15) ou la paroi rocheuse d'un ouvrage de tunnel. L'invention propose à cet effet des arceaux de serrage (4) ou des bagues de serrage formés à partir d'un ou de plusieurs segments (23, 24) d'arceau composés de barres en acier d'armature individuelles, de corps d'appui de serrage (2) en forme de M pourvus d'une zone de liaison avec les arceaux de serrage, ainsi que de bras de soutien servant à assembler par serrage, tout en produisant un espacement par rapport à une coque extérieure (15) ou une paroi rocheuse l'arceau et d'écarteurs sur les corps d'appui de serrage (2) et entre la couche extérieure (19) et une couche intérieure (20) de l'armature.
