<\/span>Aper\u00e7u du projet<\/span><\/h2>\n\n\n\n

Nom du projet :<\/strong> Usine de traitement de farine Mandela Millers<\/p>\n\n\n\n

Localisation :<\/strong> Busega, Kampala, Ouganda<\/p>\n\n\n\n

Surface totale : <\/strong>11 650 SQM<\/p>\n\n\n\n

Dimensions :<\/strong> 52m (L) \u00d7 23m (L) \u00d7 32m (H) (7 \u00e9tages)<\/p>\n\n\n\n

Contexte du projet :<\/strong> Point de rep\u00e8re dans la zone industrielle de Kampala, ce projet se caract\u00e9rise par une conception verticale unique de 7 \u00e9tages. Utilisant une structure en acier ultra-haute de 32 m\u00e8tres, il supporte l'ensemble de la cha\u00eene de production quotidienne de 300 tonnes. Il s'agit d'une r\u00e9f\u00e9rence en mati\u00e8re de b\u00e2timents industriels \u00e0 grande \u00e9chelle et \u00e0 structure en acier en Afrique de l'Est.<\/p>\n\n\n\n

<\/p>\n\n\n\n

<\/span>Faits marquants et solutions techniques<\/span><\/h2>\n\n\n\n

- Syst\u00e8me structurel robuste (ossature m\u00e9tallique de grande hauteur)<\/strong><\/p>\n\n\n\n

Conception :<\/strong> Nous avons opt\u00e9 pour un cadre rigide \u00e0 plusieurs \u00e9tages associ\u00e9 \u00e0 un syst\u00e8me de r\u00e9sistance aux forces lat\u00e9rales par contreventement, et la structure principale utilise des colonnes en H robustes et des poutres en acier \u00e0 section variable, ce qui est \u00e0 la fois solide et pratique.<\/p>\n\n\n\n

Stabilit\u00e9 :<\/strong> Chaque \u00e9tage est dot\u00e9 d'un contreventement horizontal de type X, qui r\u00e9siste parfaitement aux charges de vent \u00e0 32 m\u00e8tres et aux vibrations produites par les \u00e9quipements de broyage lourds. Cela garantit une stabilit\u00e9 structurelle \u00e0 long terme, m\u00eame dans l'environnement local de l'Ouganda.<\/p>\n\n\n\n

-Construction rapide (assemblage pr\u00e9fabriqu\u00e9)<\/strong><\/p>\n\n\n\n

Efficacit\u00e9 :<\/strong> Nous avons eu recours \u00e0 une pr\u00e9fabrication modulaire compl\u00e8te pour ce projet, ce qui a consid\u00e9rablement simplifi\u00e9 le travail sur site - seuls des assemblages par boulons \u00e0 haute r\u00e9sistance et un peu de soudure ont \u00e9t\u00e9 n\u00e9cessaires.<\/p>\n\n\n\n

Installation :<\/strong> Nous avons d\u00e9ploy\u00e9 de grandes grues sur chenilles pour un levage synchronis\u00e9, ce qui a permis un assemblage rapide et sans heurts. Par rapport aux b\u00e2timents en b\u00e9ton, cela a permis de r\u00e9duire consid\u00e9rablement le cycle de construction.<\/p>\n\n\n\n

-Anti-corrosion avanc\u00e9e (peinture \u00e9poxy riche en zinc)<\/strong><\/p>\n\n\n\n

Protection : <\/strong>Au lieu d'un rev\u00eatement ordinaire, nous avons opt\u00e9 pour un syst\u00e8me de peinture anticorrosion \u00e9poxy riche en zinc, beaucoup plus durable pour ce type d'installation.<\/p>\n\n\n\n

Capacit\u00e9 d'adaptation : <\/strong>Ce syst\u00e8me est sp\u00e9cialement con\u00e7u pour r\u00e9sister aux temp\u00e9ratures et \u00e0 l'humidit\u00e9 \u00e9lev\u00e9es, ainsi qu'\u00e0 la corrosion par la poussi\u00e8re de farine - autant de maux de t\u00eate courants dans les environnements de transformation des aliments.<\/p>\n\n\n\n

- Rev\u00eatement mural de qualit\u00e9 sup\u00e9rieure (PU et laine de roche)<\/strong><\/p>\n\n\n\n

Mat\u00e9riau :<\/strong> Panneaux sandwichs en laine de roche scell\u00e9s aux bords par du PU.<\/p>\n\n\n\n

Performance :<\/strong> Ces panneaux offrent trois avantages cl\u00e9s qui conviennent parfaitement \u00e0 une minoterie : Une r\u00e9sistance au feu de classe A, une excellente isolation thermique et une forte \u00e9tanch\u00e9it\u00e9. Ils bloquent efficacement la chaleur et la poussi\u00e8re ext\u00e9rieures, ce qui permet de maintenir une temp\u00e9rature constante et un environnement hygi\u00e9nique essentiels \u00e0 la production de farine.<\/p>\n\n\n\n

- Conception fonctionnelle (lumi\u00e8re, air et logistique)<\/strong><\/p>\n\n\n\n

Ventilation : <\/strong>Nous avons plac\u00e9 des fen\u00eatres vitr\u00e9es de mani\u00e8re uniforme sur la fa\u00e7ade du b\u00e2timent afin de maximiser la lumi\u00e8re naturelle et la circulation de l'air. Cela permet non seulement de r\u00e9duire la consommation d'\u00e9nergie pour la ventilation m\u00e9canique, mais aussi de diminuer le risque d'accumulation de poussi\u00e8re - un facteur cl\u00e9 pour la transformation des aliments.<\/p>\n\n\n\n

Logistique : <\/strong>Le rez-de-chauss\u00e9e est \u00e9quip\u00e9 de grandes portes industrielles \u00e0 volets roulants, ce qui facilite et acc\u00e9l\u00e8re le chargement des c\u00e9r\u00e9ales et des produits finis dans les camions et permet de rationaliser les op\u00e9rations quotidiennes.<\/p>\n\n\n\n

Flux vertical : <\/strong>Nous avons int\u00e9gr\u00e9 le syst\u00e8me de transport vertical au squelette en acier, ce qui permet aux c\u00e9r\u00e9ales brutes de circuler efficacement depuis le sol jusqu'aux lignes de traitement de haut niveau. Cette conception intelligente augmente l'efficacit\u00e9 de la production de plus de 30%.<\/p>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":12903,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"themepark_post_bcolor":"#ffffff","themepark_post_width":"1022px","themepark_post_img":"","themepark_post_img_po":"left","themepark_post_img_re":false,"themepark_post_img_cover":false,"themepark_post_img_fixed":false,"themepark_post_hide_title":true,"themepark_post_main_b":"#ffffff","themepark_post_main_p":100,"themepark_paddingblock":true,"footnotes":""},"categories":[29],"tags":[],"class_list":["post-12895","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-project-case"],"metadata":{"_edit_lock":["1768976913:1"],"rank_math_seo_score":["15"],"_thumbnail_id":["12903"],"themepark_post_bcolor":["#ffffff"],"themepark_post_width":["1022px"],"themepark_post_img":[""],"themepark_post_img_po":["left"],"themepark_post_img_re":[""],"themepark_post_img_cover":[""],"themepark_post_img_fixed":[""],"themepark_post_hide_title":["1"],"themepark_post_main_b":["#ffffff"],"themepark_post_main_p":["100"],"themepark_paddingblock":["1"],"footnotes":[""],"_edit_last":["1"],"_ez-toc-disabled":[""],"_ez-toc-insert":[""],"_ez-toc-header-label":[""],"_ez-toc-device-target":[""],"_ez-toc-alignment":["none"],"_ez-toc-heading-levels":["a:0:{}"],"_ez-toc-alttext":[""],"_ez-toc-visibility_hide_by_default":[""],"_ez-toc-hide_counter":[""],"_ez-toc-exclude":[""],"_ez-toc-word_count_limit":["0"],"_ez-toc-position-specific":[""],"product_title":[""],"_product_title":["field_696dcb32bdf4a"],"product_description":[""],"_product_description":["field_696dcb5bbdf4b"],"product_parametertitle":[""],"_product_parametertitle":["field_696dcb64bdf4c"],"product_parameter1":[""],"_product_parameter1":["field_696dcb6bbdf4d"],"product_parameter2":[""],"_product_parameter2":["field_696dcb77bdf4e"],"product_parameter3":[""],"_product_parameter3":["field_696dcb7bbdf4f"],"product_parameter_description1":[""],"_product_parameter_description1":["field_696dcb80bdf50"],"product_parameter_description2":[""],"_product_parameter_description2":["field_696dcb87bdf51"],"product_parameter_description3":[""],"_product_parameter_description3":["field_696dcb8bbdf52"],"characteristics_tittle":[""],"_characteristics_tittle":["field_696dcb93bdf53"],"characteristics_tittle1":[""],"_characteristics_tittle1":["field_696dcb9abdf54"],"characteristics_tittle2":[""],"_characteristics_tittle2":["field_696dcb9dbdf55"],"characteristics_tittle3":[""],"_characteristics_tittle3":["field_696dcba0bdf56"],"characteristics_tittle4":[""],"_characteristics_tittle4":["field_696dcba3bdf57"],"characteristics_tittle5":[""],"_characteristics_tittle5":["field_696dcbb1bdf58"],"characteristics_tittle6":[""],"_characteristics_tittle6":["field_696dcbc0bdf59"],"characteristics_description1":[""],"_characteristics_description1":["field_696dcbc3bdf5a"],"characteristics_description2":[""],"_characteristics_description2":["field_696dcbcdbdf5b"],"characteristics_description3":[""],"_characteristics_description3":["field_696dcbd2bdf5c"],"characteristics_description4":[""],"_characteristics_description4":["field_696dcbd6bdf5d"],"characteristics_description5":[""],"_characteristics_description5":["field_696dcbdabdf5e"],"characteristics_description6":[""],"_characteristics_description6":["field_696dcbdebdf5f"],"detailed_specifications_table":[""],"_detailed_specifications_table":["field_696deea21804d"],"comparison_points_tittle":[""],"_comparison_points_tittle":["field_696dcbeabdf60"],"comparison_points_description":[""],"_comparison_points_description":["field_696dcbf3bdf61"],"comparison_points_tittle1":[""],"_comparison_points_tittle1":["field_696dcbfebdf62"],"comparison_points_tittle2":[""],"_comparison_points_tittle2":["field_696dcc05bdf63"],"comparison_points_tittle3":[""],"_comparison_points_tittle3":["field_696dcc0dbdf64"],"comparison_points_description1":[""],"_comparison_points_description1":["field_696dcc13bdf65"],"comparison_points_description2":[""],"_comparison_points_description2":["field_696dcc19bdf66"],"comparison_points_description3":[""],"_comparison_points_description3":["field_696dcc1dbdf67"],"application_title":[""],"_application_title":["field_696dcc20bdf68"],"application_title1":[""],"_application_title1":["field_696dcc2bbdf69"],"application_title2":[""],"_application_title2":["field_696dcc31bdf6a"],"application_title3":[""],"_application_title3":["field_696dcc34bdf6b"],"application_title4":[""],"_application_title4":["field_696dcc37bdf6c"],"application_describe1":[""],"_application_describe1":["field_696dcc3abdf6d"],"application_describe2":[""],"_application_describe2":["field_696dcc41bdf6e"],"application_describe3":[""],"_application_describe3":["field_696dcc45bdf6f"],"application_describe4":[""],"_application_describe4":["field_696dcc48bdf70"],"instruction_title":[""],"_instruction_title":["field_696dc
