Vesam d\u00e9veloppe un nouveau type de plancher m\u00e9tallique \u00e0 haut rendement et d’appareils d\u2019appui \u00e0 faible co\u00fbt.<\/span><\/p>\n

L’invitation \u00e0 concevoir et construire un pont m\u00e9tallique temporaire sur le fleuve Mpozo , dans la province du Za\u00efre en Angola, a \u00e9t\u00e9 le banc d’essai pour la recherche et le d\u00e9veloppement de deux \u00e9l\u00e9ments structuraux innovants.<\/span><\/p>\n

L’\u00e9quipe d’ing\u00e9nierie de Vesam a parti pour le d\u00e9veloppement d’un tablier modulaire capable d’optimiser les temps de fabrication et d’assemblage.<\/span><\/p>\n

<\/p>\n

Pour sa conception, un logiciel de pointe sp\u00e9cialis\u00e9 dans l’analyse par \u00e9l\u00e9ments finis a \u00e9t\u00e9 utilis\u00e9, qui a \u00e9t\u00e9 compl\u00e9t\u00e9 par l’ex\u00e9cution de prototypes soumis \u00e0 des tests de charge dans le laboratoire structurel de Vesam.<\/span><\/p>\n \t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

En plus de contribuer \u00e0 all\u00e9ger le poids structurel total d’un pont, ce concept est d’une \u00e9norme simplicit\u00e9 de montage, permettant la r\u00e9duction du temps d’intervention.<\/span><\/p>\n

En compl\u00e9ment de cette innovation, et compte tenu des d\u00e9lais rallong\u00e9s habituels dans la fourniture de solutions d\u2019appareils d\u2019appui commerciaux, Vesam a d\u00e9velopp\u00e9 deux types d\u2019appareils d\u2019appui pour ce pont, mobile unidirectionnel et fixe, inspir\u00e9s sur les mod\u00e8les classiques.<\/span><\/p>\n

<\/p>\n

Ces mod\u00e8les construits sur mesure, en plus d’\u00eatre peu co\u00fbteux, ont permis de raccourcir encore plus le temps d’ex\u00e9cution du pont.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Ces innovations ont \u00e9t\u00e9 appliqu\u00e9es dans un contexte r\u00e9el dans la construction du pont de Mbanza Congo qui s’\u00e9tend sur une port\u00e9e de 40 m\u00e8tres \u00e0 travers un syst\u00e8me structurel compos\u00e9 de deux poutres en treillis m\u00e9talliques du type bowstring situ\u00e9es sur le c\u00f4t\u00e9 et au-dessus du tablier.<\/span><\/p>\n

La structure supporte le tablier en t\u00f4le m\u00e9tallique de 4,5 m de large, qui accueille une plate-forme routi\u00e8re avec une voie centrale de 3,50 m et une voie lat\u00e9rale de 1,00 m de large.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
