Abstract

L'invention concerne un segment composite permettant la formation d'une structure continue composée d'une partie béton et d'une partie acier. Ces segments présentent une jonction adéquate lorsqu'ils sont assemblés, et conviennent en particulier comme matériau de revêtement d'un tunnel destiné à une conduite d'eau. Une pluralité d'armatures (13) principales et d'armatures (14) de cisaillement sont disposées dans une coque (12) d'acier formée de plaques (1) transversales principales, de plaques (2) de jonction et de plaques (3) de fond et cette coque est remplie de béton (15). Des structures d'assemblage comportant des évidements (7) à queue d'aronde et des clavettes (8) sont formées sur deux niveaux, sur l'intérieur et sur l'extérieur des plaques (2) de jonction. Des protubérances (10) de fixation sont formées sur les plaques (2) de jonction, et des plaques (16) de fixation comprenant des orifices (16a) de fixation sont disposées de manière à s'avancer sur la partie terminale des armatures (13) principales. On introduit les protubérances (10) de fixation dans les orifices (16a) afin de fixer les parties (13a) terminales des armatures (13) principales sur les plaques (2) de jonction.
