Abstract
A self-supporting reinforcement system for the concrete lining of the inner shell of a tunnel construction. At least one object is that of supporting the outer shell or rock wall of a tunnel construction. According to an embodiment of the invention, this is achieved by tension brackets or tension rings, formed from one or more bracket segments made of individual reinforcing steel bars. M-shaped tensioning support bodies having a connecting region to the tension brackets, and support arms for the supporting bracing, establishing the spacing with respect to an outer shell or rock wall, of the bracket and spacers on the tensioning support bodies and between the outer layer and an inner layer of the reinforcement.
Claims20
A self-supporting reinforcement system for the concrete lining of the inner shell of a tunnel construction including
- tensioning arches or tensioning rings with an adaptable arch length or an adaptable ring circumference formed from at least two arch segments for forming a tunnel reinforcement arch or tunnel reinforcement ring for the reinforcement of the inner shell of the tunnel construction for support for at least one outer layer produced at least from reinforced steel meshes,
- wherein the arch segments are each formed from an individual reinforcement steel rod,
- tensioning support bodies with a connecting region to the tensioning arches and at least one support arm for tensioning the tensioning arches or tensioning rings on the outer shell or rock face wall of the tunnel construction in a supporting manner and producing the spacing with respect to an outer shell or to the rock face wall,
- spacers on the tensioning support bodies for support on the outer shell or rock face wall of the tunnel construction and for generating the minimum concrete coverage of the installed reinforced concrete parts and
- spacers between the outer layer and an inner layer of the reinforcement.
