Method for producing a multi-layered reinforced concrete element

Abstract

The invention relates to a method for producing a multi-layered reinforced concrete element ( 10 ), comprising at least one first concrete wall section ( 11 ) in composite with a reinforcement body ( 13 ), wherein the concrete element ( 10 ) comprises an insulating layer ( 14 ), which lies at least indirectly against the first concrete wall section ( 11 ), and wherein the reinforcement body ( 13 ) is formed at least partially so as to protrude from the first concrete wall section ( 11 ) and so as to penetrate the insulating layer ( 14 ), involving the following steps of: preparing the composite of the first concrete wall section ( 11 ) with the reinforcement body ( 13 ) that at least partially protrudes therefrom; preparing a fill ( 15 ), in particular in an upwardly open fill container ( 23 ); arranging the first concrete wall section ( 11 ) with the reinforcement body ( 13 ) arranged thereon over the surface of the fill ( 15 ) such that a protruding section ( 13 ′) of the reinforcement body ( 13 ) is arranged on the underside of the first concrete wall section ( 11 ) and is only partially immersed into the fill ( 15 ) such that a vertical free space ( 16 ) remains between the surface of the fill ( 15 ) and the underside of the first concrete wall section ( 11 ); filling the free chamber ( 16 ) with a reaction mixture, and curing the reaction mixture ( 14 ) so as to form the insulating layer ( 14 ).
