Abstract

La présente invention concerne un procédé pour fabriquer un élément de construction en béton qui est pourvu d'une couche de couverture ignifuge. Ledit procédé comprend les étapes suivantes qui consistent (i) à mettre à disposition un coffrage pour l'élément de construction à fabriquer, (ii) à couler le béton requis pour l'élément de construction dans le coffrage, et (iii) à permettre au béton coulé conformément à l'étape (ii) de durcir afin d'obtenir l'élément de construction, le coffrage étant au moins partiellement formé par un panneau ignifuge, lequel panneau est conçu pour s'accoupler avec l'élément de construction destiné à être obtenu par durcissement du béton conformément à l'étape (iii). La présente invention concerne également un élément de construction en béton fabriqué selon ledit procédé et un tunnel pourvu d'au moins un tel élément de construction en béton.
