Embodiment 1
[0036] like figure 1Shown, a kind of glued bamboo board, comprises upper layer 1, middle layer 2, lower layer 3; Described upper layer 1 and lower layer 3 are reorganized bamboo boards, and the bamboo filament arrangement direction of described reorganized bamboo board is the same as that of its own board The surface is vertical; the density of the glued bamboo board is 1.5 g / cm 3 , the moisture content is 8.0%, the thickness expansion rate after 24 hours of water absorption is 2.0%, the static bending strength is 120 MPa, and the surface hardness is 90 MPa. The bamboo filaments of the reconstituted bamboo board include carbonized and non-carbonized bamboo filaments, and irregular patterns are formed after hot pressing. The degree of carbonization of the carbonized bamboo silk is also different. The middle layer 2 is a three-layer bamboo flat-pressed plywood, and the bamboo filaments of two adjacent bamboo-chip flat-pressed plywood are perpendicular to each other.

Embodiment 2
[0048] like figure 2 Shown, a kind of glued bamboo board, comprises upper layer 1, middle layer 2, lower layer 3; Described upper layer 1 and lower layer 3 are reorganized bamboo boards, and the bamboo filament arrangement direction of described reorganized bamboo board is the same as that of its own board The surface is vertical; the density of the glued bamboo board is 1.4 g / cm 3 , the moisture content is 8.0%, the thickness expansion rate after 24 hours of water absorption is 2.0%, the static bending strength is 120 MPa, and the surface hardness is 90 MPa. The bamboo filaments of the reconstituted bamboo boards are all bamboo filaments that have not been carbonized. The middle layer 2 is a side-pressed plywood with bamboo pieces.
[0049] The said bamboo side-pressed plywood means that after cutting the bamboo into pieces, removing the green and yellowing, and then making the bamboo pieces of a predetermined specification, then the bamboo pieces are glued and stacked wit...
Embodiment 3
[0059] like image 3 As shown, a kind of glued bamboo board, including upper layer 1, middle layer 2, lower layer 3; Described upper layer 1 and lower layer 3 are reorganized bamboo boards, and the bamboo filament direction of described reorganized bamboo board is the same as that of its own board surface Vertical; the density of the glued bamboo board is 1.6 g / cm 3 , the moisture content is 14.0%, the thickness expansion rate after 24 hours of water absorption is 2.0%, the static bending strength is 180 MPa, and the surface hardness is 140 MPa. The bamboo filaments of the reconstituted bamboo boards are all non-carbonized bamboo filaments. The middle layer 2 is a two-layer bamboo flat-pressed plywood, and the bamboo filaments of the two adjacent layers of bamboo-chip flat-pressed plywood are perpendicular to each other. The thickness of the reconstituted bamboo board is 10mm; the thickness of a single layer of the two-layer bamboo plywood is 4mm.
