Detailed description of the invention
As Figure 1-Figure 4, the present embodiment three-layer wood composite flooring, comprise central layer 1, cover panel 2 in this central layer front, and cover the backboard 3 with this central layer back side, described central layer 1 comprises the middle plate 1-1 adopting multilayer solid wood board to make, and be arranged in this plate surrounding and be spliced into it the wooden side plate (deriving from the economic class seeds of fast-growing) of integral planar structure, described middle plate 1-1 and wooden side plate are positioned at same plane; Described panel 2 is identical with floor length direction with the machine direction of backboard 3.
Described wooden side plate is spliced into middle plate 1-1 encirclement " mouth " glyph framework structure within it by two pieces of longitudinal plank 1-2 and two piece horizontal plank 1-3, and the machine direction of longitudinal plank 1-2 is identical with the length direction on floor, the machine direction of horizontal plank 1-3 and the length direction on floor perpendicular; Thus achieve " the vertical incorgruous combination " of wooden side plate in same level, control the internal stress of sheet material in length and breadth in both direction, reduce the probability of sheet deformation.
In this example, two long limits of described middle plate 1-1 are respectively spliced a batten 1-5, each batten opposite side splicing has a bamboo waling 1-4, each waling 1-4 opposite side and described longitudinal plank 1-2 are spliced to form integral planar structure, and described waling 1-4 is all identical with the length direction on floor with the machine direction of batten 1-5; Two minor faces of described integral planar structure (planar rectangular be made up of middle plate, two battens, two walings and two pieces of longitudinal planks) respectively splice a bamboo cross reinforcing 1-6 (cross reinforcing is all withstood in the end of two battens, two walings and two pieces of longitudinal planks), each cross reinforcing 1-6 opposite side and described horizontal plank 1-3 splice, thus forming the central layer 1 of integral planar structure, machine direction and the floor length direction of described cross reinforcing 1-6 are perpendicular; Utilize bamboo wood consistency and elasticity to be greatly better than the characteristic of natural timber, after making compound, the anti-bending strength of sheet material and elasticity are far longer than the sheet material of timber and timber direct combination, further increase the non-deformability of sheet material.
In order to strengthen the bond strength between each several part, the cross section on the mating face of the present embodiment waling 1-4 and longitudinal plank 1-2, batten 1-5, and cross reinforcing 1-6 and middle plate 1-1, longitudinal plank 1-2, horizontal plank 1-3 the cross section on mating face all in comb teeth-shaped.Specific implementation is by the mating face of waling 1-4 and longitudinal plank 1-2, batten 1-5, and cross reinforcing 1-6 and middle plate 1-1, longitudinal plank 1-2, horizontal plank 1-3 mating face be processed into comb teeth-shaped, use lateral pressure when producing much larger than conventional composite material during hot pressing, make the comb teeth-shaped mating face of bamboo cane (reinforcing rib) embed the plane engaging surface of timber thus the effect of formation " toe joint ".
Described longitudinal plank 1-2 and horizontal plank 1-3 is solid wood finger-jointed plate or solid wood board; In practical application, if longitudinal plank 1-2 and/or horizontal plank 1-3 is solid wood finger-jointed plate, then must arrange waling 1-4 and/or cross reinforcing 1-6, to improve the tensile strength of solid wood finger-jointed plate.
In actual production process, middle plate 1-1 can also select solid wood jigsaw (as shown in Figure 5), solid wood finger-jointed plate (as shown in Figure 6), solid-wood (as shown in Figure 7) and Integral bamboo veneer (as shown in Figure 8), its machine direction and floor length direction perpendicular.
The production technology on the present embodiment floor is:
Step one, central layer 1 make: by multilayer solid wood board, solid wood jigsaw, solid wood finger-jointed plate, solid-wood or bamboo wood by design size sawing, obtain middle plate 1-1, for subsequent use; The middle plate 1-1 machine direction that wherein solid wood jigsaw, solid wood finger-jointed plate, solid-wood and bamboo wood are shaping and floor length direction perpendicular; Scab without broken, nothing, without after the fast-growing class timber stoving of small holes caused by worms, size into longitudinal plank 1-2 and horizontal plank 1-3; On the adhesive surface of each several part after brushing Environment-friendlyglue glue, bond according to aforementioned structure, then entirety is put into press and is pressed into integral planar structure, obtains central layer 1.
Step 2, panel 2 make: choose the seeds log that can be used for decoration panel and make, after the operations such as the side of getting, oven dry, slicing, product choosing, namely obtain panel 2.
Step 3, backboard 3 make: choose fast growing wood log, after the operations such as peeling, rotary-cut, oven dry, product choosing, namely obtain backboard 3.
Step 4, sticky face: step one gained central layer 1 is carried out two sides sanding, and is coated with Environment-friendlyglue glue, then two sides is respectively coated with panel 2 and backboard 3, and puts into hot press hot pressing veneer.
Step 5, carry out the follow-up finished product floor such as tongue and groove, paint production process.
