Title
(EN) A CONCRETE FORMWORK CASTING PANEL, A METHOD OF MANUFACTURING THE SAME, AND USE THEREOF
(FR) PANNEAU DE COULAGE DE COFFRAGE EN BÉTON, PROCÉDÉ DE FABRICATION ET D'UTILISATION ASSOCIÉS
Abstract
(EN)
A method of manufacturing a concrete formwork casting panel and a panel thus obtained. The panel is multiply wood-veneer panel having a coating layer which forms a casting surface. The method comprising the steps of stacking a plurality of wood-veneer layers on top of each other to form a stack with a top wood-veneer layer having an upper surface facing the casting surface and an opposite lower surface facing the other wood-veneer layers of the stack; providing layers of an adhesive resin between the wood-veneer layers; and in optional order coating the upper surface of the top wood-veneer layer to provide a coated stack and pressing the stack using increased pressure and temperature in order to form a multiply wood-veneer product with a coating layer. According to the invention, on the upper surface of the top wood-veneer a hydrophobic agent is applied before coating of the upper surface and on the lower surface of the top wood-veneer an impregnation resin is applied, such that the top wood-veneer of the formwork casting panel becomes at least partially saturated with the hydrophobic agent and impregnated with the impregnation resin.

L'invention concerne un procédé de fabrication d'un panneau de coulage de coffrage en béton et un panneau ainsi obtenu. Le panneau est un panneau de placage de bois multicouche ayant une couche de revêtement qui forme une surface de coulage. Le procédé comprend les étapes consistant à empiler une pluralité de couches de placage de bois les unes sur les autres pour former un empilement, une couche de placage de bois supérieure ayant une surface supérieure faisant face à la surface de coulage et une surface inférieure opposée faisant face aux autres couches de placage de bois de l'empilement ; fournir des couches d'une résine adhésive entre les couches de placage de bois ; et, dans un ordre facultatif, recouvrir la surface supérieure de la couche de placage de bois supérieure pour former un empilement revêtu et presser l'empilement au moyen d'une pression et d'une température accrues afin de former un produit de placage de bois de multiplication à couche de revêtement. Selon l'invention, sur la surface supérieure du placage de bois supérieur, un agent hydrophobe est appliqué avant le revêtement de la surface supérieure, et une résine d'imprégnation est appliquée sur la surface inférieure du placage de bois supérieur, de sorte que le placage de bois supérieur du panneau de coulage de coffrage devienne au moins partiellement saturé en agent hydrophobe et imprégné de la résine d'imprégnation.
