Underfloor remote-heating rail

摘要

The invention relates to an underfloor remote-heating rail, consisting of a tubular tunnel completed in reinforced concrete as well as at least one pipe section carrying the heating medium, the pipes of which are insulated on the outside and are arranged above and are supported on a concreted tunnel-support base. The invention consists in the fact that the insulated pipes and the tunnel sections allocated to them form transportable construction units in which the pipe carrying the heating medium is surrounded by an envelope formed by the pipe insulation and a reinforced-concrete body bearing against the pipe insulation and serving as tunnel support including the tunnel base, which envelope leaves the pipe ends free, the connection of which is accommodated in a collar which has a vapour and/or liquid barrier at which the insulation and/or the successive reinforced-concrete bodies terminate.
