The addition relates to an improvement to the device for manufacturing cellular structures according to the main patent. The device according to the invention comprises, downstream of the cooling stage 2, a laying-down device 4 for depositing a thermal-insulation covering 5 on one of the lateral faces of the produced cellular element 3, and a second laying-down device 6 for fixing, on the opposite lateral face of the element 3, a catching covering 7 intended for retaining a subsequently deposited coating. The addition also relates to structural elements made with the aid of this device and which comprise a cellular central portion, one of the lateral faces of which is fitted with an insulation covering 5 whereas the opposite lateral face carries a catching covering 7. L'ADDITION CONCERNE UN PERFECTIONNEMENT AU DISPOSITIF DE FABRICATION DES STRUCTURES ALVEOLAIRES SUIVANT LE BREVET PRINCIPAL. LE DISPOSITIF SELON L'INVENTION COMPREND EN AVAL DE L'ETAGE DE REFROIDISSEMENT2 UN DISPOSITIF DE POSE4 POUR DEPOSER SUR L'UNE DES FACES LATERALES DE L'ELEMENT ALVEOLAIRE PRODUIT3 UN REVETEMENT D'ISOLATION THERMIQUE5 ET UN DEUXIEME DISPOSITIF DE POSE6 POUR FIXER SUR LA FACE LATERALE OPPOSEE DE L'ELEMENT3 UN REVETEMENT D'ACCROCHAGE7 DESTINE A RETENIR UN ENDUIT DEPOSE ULTERIEUREMENT. L'ADDITION VISE EGALEMENT DES ELEMENTS DE CONSTRUCTION REALISES A L'AIDE DE CE DISPOSITIF ET QUI COMPRENNENT UNE PARTIE CENTRALE ALVEOLAIRE DONT L'UNE DES FACES LATERALES EST MUNIE D'UN REVETEMENT D'ISOLATION5 TANDIS QUE LA FACE LATERALE OPPOSEE PORTE UN REVETEMENT D'ACCROCHAGE7.
