Building plate

Abstract

PURPOSE: To improve dimensional stability and workability by carbon fiber reinforced resin composite material on a wooden base plate. CONSTITUTION: A laminated plate formed by integrally stacking a surface wood fiber layer 2, an intermediate wood veneer layer 3 and a back wood veneer layer 5 in order from the surface side is used as a base plate 1 for a building plate used in a flooring material or the like, a decorated sheet 6 is stuck to the surface of the base plate and a moisture-proof sheet 9 is stuck to the back thereof. The moisture-proof sheet 9 is of a three-layer structure where a polyethylene sheet 7 is used as a core layer, and kraft paper 8, 8' is stacked on the surface and back thereof, made adhere to the back wood veneer layer 5 of the base plate back at the surface kraft paper 8, and made adhere to the under floor ground at the back kraft paper 8'. In the base plate 1, both the fiber directions of the intermediate wood veneer layer 3 and the back wood veneer layer 5 are made parallel to the longitudinal direction of the flooring material.
