The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Description of reference numerals is as follows:

1---main body 2---tenon

3---groove 4---balance ply of paper

5---walking surface 6---obtuse angle folding surface

7---wood grain ply of paper 7 '---wood grain ply of paper among second embodiment

8---wearing layer 9---resin varnish layer

The big plate of 10---trapezoidal grooves 11---

12---the cutting warp

As Fig. 1, Fig. 2, first embodiment shown in Figure 3, its main body 1 is a high density fiberboard, have tenon 2 and groove 3 all around, fiberboard is below by the gluing balance ply of paper 4 that is connected to of environmental protection, have moistureproof and fire-retardant effect, floor upper surface is made up of the obtuse angle folding surface 6 of walking surface 5 that parallels with the bottom surface and walking surface long side direction both sides of the edge, floor upper surface is bonded with wood grain ply of paper 7 and wearing layer 8 successively by environmental protection glue, can print various decorative patterns on the wood grain ply of paper 7, satisfy different needs, wearing layer 8 surfaces have the alundum (Al particle, can effectively prevent the floor wearing and tearing, prolong its application life.

As Fig. 5, shown in Figure 6, the length a on floor is that 2000mm, width b are that 200mm, thickness c are 15mm, the floor is after splicing, every floor only forms trapezoidal groove 10 in both sides by the obtuse angle folding surface, the degree of depth h of trapezoidal groove 10 is 0.45mm, and A/F is 0.5mm, and the angle α of its hypotenuse and bottom surface is 40 °, whole structure is uniform, very outstanding of visual effect.
