The invention has the beneficial effects as follows: the conventional surf green of the contrary tradition of board-splicing process by using of the present invention is that face, tabasheer are the suitable spelling of lining, change bluish yellow into and intersect positive and negative jigsaw method, allow blue or green face of bamboo wood and yellow bamboo face oneself mutual restriction rises because of wetting, drying shrinkage causes unusual contrast with this, balance two sides mechanical strength, the planeness of reinforcement bamboo veneer integral body.And carried out following contrast test:

Test 1: adopted four kinds of jigsaw methods: A-bluish yellow is intersected positive and negative jigsaw method, and B-blue or green face is vertical along spelling, and C-big inclination of blue or green face Xiao Huang face is along spelling, and D-little inclination of blue or green face rheum officinale face is along spelling.Become the lath of the thick 5mm of the wide 80mm x of long 320mm x of same specification to put into 100 ℃ of boiling water boilings above-mentioned sheet material sawing and took out in 0.5 hour, the A plate is vertically vertical good, laterally smooth; B plate, C plate, D plate are vertically vertical good, and horizontal watt of Qu Yanchong measures Wa Duda 6mm from lath end face center.

Test 2: will the above-mentioned lath that takes out keeping flat on the steel mesh of baking oven middle level 70 ℃ of constant temperature from boiling water, take out after 15 hours, is 8% through measuring moisture content, and the A plate vertically vertically well, and is laterally smooth; It is smooth that B plate, C plate, D plate laterally recover, and buckling is serious, and measuring camber from center, lath edge is 8mm.

Test 3: the blue or green face of bamboo bar is the long-term and the Nature intimate contact of the thin bamboo skin of alternating floor only, so its color will be deeper than yellow bamboo face about 10%, select the yellow hand-deliver fork of blue or green face of light bamboo bar and dark bamboo bar collocation jigsaw for use, the result shows that the bamboo veneer surface chromatic aberration after the amalgamation is less.

The present invention can economize on resources and the comparison of the thick bamboo of normal conventional floor greatly owing to adopt the individual layer bamboo clappers, save the forest reserves more than 70%, save bonding adhesive more than 65%, and can save a large amount of mat formation expense and auxiliary material, mat formation, remove and change convenient and swift, zero loss.The good high resilience of floor sound insulation value, the multiple pattern of one-tenth capable of being combined.Environmental protection is applicable to the indoor and outdoor, and recyclable utilization.Bamboo wood tension compressive property is good, and the bamboo wood tensile strength parallel to the grain is 18000N/cm ², being steel tensile strength 1/2, crushing strength parallel to the grain is 7000N/cm ², be steel compressive strength 1/5, because the material of bamboo wood is tough and tensile,,, bear a heavy burden can carry to press owing to fit well in carrier and ground though the present invention has adopted the bamboo veneer, reach the application life on normal thick bamboo floor.
