Abstract

La présente invention concerne un coffrage à base de bois et un procédé de préparation de coffrage à base de bois. Selon cette invention, les composants de matière première utilisés et leur rapport de poids sont : laine de bois 0,5-1 tonne, ciment au silicate 0,5-4 tonnes et eau 0,1-1 tonne. Le procédé consiste (1) à traiter les matières premières, (2) à mouiller la laine de bois, (3) à mélanger les matières premières, (4) à traiter le mélange, (5) à le mettre en moule, (6) à mouler par compression, (7) à laisser prendre, (8) à démouler, puis (9) à apprêter le produit fini. Cette invention est caractérisée par la plus faible quantité de bois utilisée et par la plus vaste gamme d'applications possibles. Elle peut non seulement s'appliquer sous forme de moule lié au béton à utiliser pour un mur porteur extérieur/intérieur d'un bâtiment, mais également sous forme de mur porteur ou non porteur intérieur d'un bâtiment en fonction de la densité de la laine de bois. De plus, la laine de bois de surface présente une force d'adhérence qui permet de l'intégrer facilement avec d'autres matériaux de construction décoratifs et le motif de la laine de bois de surface est magnifique et unique, ce qui permet d'utiliser le panneau directement comme paroi décorative.
