Nos installations Tensyland fabriquent tous types de poutrelles et dalles alv\u00e9olaires pr\u00e9contraintes<\/strong> pour la construction d\u2019auditoriums, centres commerciaux, \u00e9coles, universit\u00e9s, etc. Mais que signifie pr\u00e9contraint ? Pourquoi utiliser cette m\u00e9thode de construction et pas une autre ? Quels avantages pr\u00e9sente-t-il ?<\/p>\n

Le b\u00e9ton pr\u00e9contraint<\/strong> consiste \u00e0 \u00e9liminer les efforts de traction du b\u00e9ton en introduisant des tensions artificielles de compression avant l\u2019application des charges ext\u00e9rieures et qui, superpos\u00e9es \u00e0 celles-ci, font que les tensions totales permanentes restent comprises dans les limites que le mat\u00e9riau peut supporter ind\u00e9finiment. L\u2019utilisation de cette technique dans la construction de tous types de projets architecturaux et d\u2019ing\u00e9nierie est aujourd\u2019hui incontestable et totalement standardis\u00e9e gr\u00e2ce \u00e0 ses grands avantages.<\/p>\n

Ainsi, les principaux avantages de l\u2019utilisation de b\u00e9ton pr\u00e9contraint en construction sont les suivants :<\/p>\n

RESISTANCE STRUCTURELLE<\/strong><\/p>\n

L\u2019utilisation de la technique du pr\u00e9contraint en b\u00e9ton<\/strong> permet de doter celui-ci d\u2019une r\u00e9sistance plus \u00e9lev\u00e9e, apportant un effort de compression interne compensant l\u2019effort de traction produit par les charges des \u00e9l\u00e9ments structurels.<\/p>\n

DURABILITE DE LA CONSTRUCTION<\/strong><\/p>\n

L\u2019un des grands avantages des pi\u00e8ces pr\u00e9contraintes<\/strong> est l\u2019\u00e9limination de fissures et de craquelures dans toutes les \u00e9tapes de charge. Cette absence de fissuration est synonyme d\u2019une plus grande capacit\u00e9 de la structure \u00e0 supporter les charges, impacts, vibrations et coups, tout en r\u00e9duisant au minimum la possibilit\u00e9 de corrosion de l\u2019acier, augmentant ainsi la durabilit\u00e9 de la construction.<\/p>\n

ECONOMIES<\/strong><\/p>\n

L\u2019utilisation de pr\u00e9contraints en b\u00e9ton permet de m\u00e9nager de grandes lumi\u00e8res dans la construction gr\u00e2ce \u00e0 la longitude des pi\u00e8ces, tout en permettant des \u00e9conomies de mat\u00e9riau et en apportant de la l\u00e9g\u00e8ret\u00e9. Un exemple serait l\u2019utilisation de poutrelles pr\u00e9contraintes en b\u00e9ton<\/strong> pour la cl\u00f4ture de toits dans des espaces tr\u00e8s amples, comme des b\u00e2timents industriels, qui permet une luminosit\u00e9 plus importante. Dans le cas de fermetures pour parkings par exemple, l\u2019utilisation de plaques de b\u00e9ton donne lieu \u00e0 une s\u00e9paration plus importante de colonnes porteuses, permettant de tirer un meilleur avantage de l\u2019espace et de r\u00e9aliser des \u00e9conomies substantielles en mat\u00e9riaux.<\/p>\n

DESIGN<\/strong><\/p>\n

Gr\u00e2ce aux \u00e9l\u00e9ments pr\u00e9contraints en b\u00e9ton<\/strong>, les \u00e9l\u00e9ments architectoniques obtenus sont plus efficients et minces, et offrent une infinit\u00e9 de possibilit\u00e9s de construction.<\/p>\n

HAUTES PRODUCTIONS<\/strong><\/p>\n

Gr\u00e2ce \u00e0 la technologie de Tensyland<\/strong><\/a>, la production en s\u00e9rie de poutrelles et dalles en b\u00e9ton<\/strong> apportant des solutions \u00e0 toutes les phases du processus, et permettant un meilleur contr\u00f4le de qualit\u00e9, une r\u00e9duction des co\u00fbts et une production \u00e9lev\u00e9e, offrant ainsi une r\u00e9ponse \u00e0 des projets architecturaux de grande envergure.<\/p>\n

RAPIDITE DE LA CONSTRUCTION<\/strong><\/p>\n

Une plus grande rapidit\u00e9 de construction par le fait de pouvoir travailler en m\u00eame temps sur diff\u00e9rents fronts ou construire simultan\u00e9ment plusieurs parties de la structure ; ce qui en g\u00e9n\u00e9ral comporte d\u2019importants avantages \u00e9conomiques lors de l\u2019analyse \u00e9conomique et financi\u00e8re compl\u00e8te des travaux.<\/p>\n","protected":false},"excerpt":{"rendered":"
