Inventor: MICHEL CHARPILLOZ
IPC: E04F15/22
Filed: 1993-06-17
Abstract: La présente invention concerne un procédé de pose d'un parquet où les lambourdes traditionnelles en bois sont remplacées par des éléments intermédiaires élastiques reposant directement sur une surface de base horizontale. Comme éléments intermédiaires, on utilise des bandes souples préfabriquées (1) en matière élastique, comprenant notamment des particules de caoutchouc obtenues à partir de pneumatiques recyclés et agglomérées au moyen d'un liant élastomère. Les deux faces des bandes peuvent être revêtues d'une couche adhésive recouverte d'une feuille protectrice à retirer avant usage. On pose les bandes souples (1) espacées les unes des autres sur la surface de base (15), le cas échéant avec application de colle fraîche. On peut faire passer des câbles électriques (17) entre les bandes et à travers des passages (18) découpés dans celles-ci. On applique ensuite de la colle fraîche sur les bandes (1), puis on pose les éléments (10, 11) du parquet, reposant chacun sur au moins deux bandes. Ces éléments n'ont pas besoin d'être cloués. On obtient ainsi une importante réduction de la durée et du coût de la pose, un parquet confortable et silencieux, ainsi que la possibilité d'absorber les dilatations du parquet sans risque de fissuration.
