COMPLEX LAMINATED BAMBOO BOARD A complex laminated bamboo board includes an. upper layer (4, 4') and a plurality of lower layers (5, 5') glued to the upper one. The upper layer (4,4') consists of parallel strips (9, 9') and a pair of ribs (8, 8') alongside them. The ribs (8, 8') extend downward from a level not higher than a top face but not lower than a bottom face of the upper layer (4, 4') to below the bottom face. The lower layers (5, 5') are glued to the uppe r layer (4, 4') beneath the bottom fact and at sides of the ribs (8, 8'). In addition, the strips (9, 9') and ribs (8, 8') of the upper layer (4, 4') are made of a first woody material but th e lower layers (5, 5') are made of a second woody material different from the first woody material. |
