The utility model provides a solid wood composite floor is particularly useful for the geothermal environment in northern city.

Referring to fig. 1 to 5, the solid wood composite floor of the present embodiment includes a surface layer 1, a substrate layer 2 and a back plate 3, which are tightly connected in sequence. The side of the panel is provided with a male tenon having a tenon 42 and a female tenon having a mortise 52.

In particular, the wood texture of the surface layer 1 is aesthetically pleasing and the surface is coated with a wear-resistant paint layer. The surface layer 1 has a thickness of 2.5-4 mm, and is made of oak, birch, maple, black walnut or hickory. Preferably, in this embodiment, the surface layer 1 is made of oak board with a thickness of 3.0 mm.

Referring to fig. 6 to 8 together, the substrate layer 2 is located under the face layer 1 and is tightly adhered to the face layer 1. The base material layer 2 includes a plurality of substrates having a texture, and each adjacent substrate is connected by adhesion. The base plates form a base material layer structure with top double-layer textures in the same direction and the rest criss-cross structure.

With continued reference to fig. 6 and 8, the base material layer 2 in the present embodiment includes eight substrates with the same thickness, which are, from top to bottom, a first substrate 21, a second substrate 22, a third substrate 23, a fourth substrate 24, a fifth substrate 25, a sixth substrate 26, a seventh substrate 27, and an eighth substrate 28. The grain directions of the first substrate 21 and the second substrate 22 are parallel to each other; the grain directions of the second substrate 22 and the third substrate 23 are perpendicular to each other; the grain directions of the third substrate 23 and the fourth substrate 24 are perpendicular to each other; the grain directions of the fourth substrate 24 and the fifth substrate 25 are perpendicular to each other; the grain directions of the fifth substrate 25 and the sixth substrate 26 are perpendicular to each other; the grains of the sixth substrate 26 and the seventh substrate 27 are perpendicular to each other; the seventh substrate 27 and the eighth substrate 28 have a grain perpendicular to each other.

With the single vertically and horizontally staggered's of tradition substrate layer structure contrast, through designing the double-deck texture syntropy in top, all the other crisscross structure of violently indulging for the degree of adhesion of the two-layer base plate in top is higher, anti bending capability is stronger, and the last shoulder structure of timber apron is more stable, and then more can anti stick up the limit. Taking fig. 6 as an example, when there is a heavy pressure at the joint of two adjacent floor boards, if the pressure is at the side of the tongue of one of the floor boards, the lower shoulder of the tongue and the lower shoulder of the female tongue of the other floor board are stressed, wherein the force applied to the lower shoulder is offset by the ground. If the pressure is on the side of the female tenon of one floor, the upper shoulder of the female tenon and the tenon of the male tenon of the other floor are stressed, wherein the direction of the force borne by the upper shoulder is vertical to the grain direction of the first base plate 21 and the second base plate 22, and the first base plate 21 and the second base plate 22 generate resistance to the pressure together.

The eucalyptus wood composite floor has the advantages that the eucalyptus wood composite floor is rich in resources and low in manufacturing cost, the cost of the solid wood composite floor can be reduced, the eucalyptus wood is loose, loose capillary pores among the wood can offset the stress of swelling and shrinking of a part of the wood, and the stability is higher than that of other materials.

Wherein the thickness ratio of the upper shoulder 51, the mortise 52 and the lower shoulder 53 (H1: H2: H3) is 6:4: 5. By designing the thickness ratio of the upper shoulder 51 to the mortise 52 to the lower shoulder 53 to be 6:4:5, compared with the existing rabbet structure with the thickness of the upper plate body, the mortise to the lower plate body being trisected, the thickness ratio of the upper shoulder to the mortise 4:5 is increased, so that the upper shoulder can further resist edge warping deformation in the northern geothermal environment.

The groove wall of the first mortise 521 formed in this way is smooth and beautiful, and the notch has no burrs, so that the mortise is convenient to mortise.

The tenon 42 includes a first tenon 421 opened on the other long side of the substrate layer 2 with respect to the first mortise 521, and a second tenon 522 opened on the other short side of the substrate layer 2 with respect to the second mortise 522. Similarly, in order to reduce the difficulty of mortise closing at the long edge, the opening direction of the first tenon 421 is parallel to the texture direction of the substrate where the upper and lower surfaces of the first tenon 421 are located. Looking at the floorboard in the direction F in fig. 3, the upper surface (see fig. 7) of the first tenon 421 is located on the third base plate 23, and the third base plate 23 is smooth-grained, so that the upper inner wall is also smooth-grained. The lower surface is located on the fifth substrate 25, and the fifth substrate 25 is smooth-grained, and the lower inner wall is also smooth-grained. The surface of the first tenon 421 thus opened is relatively smooth.

Still referring to fig. 7, the back plate 3 is positioned under the eighth substrate 28 and is closely adhered to the eighth substrate 28. The thickness of the back plate 3 is 0.5mm-0.8mm, and the material is beech or poplar. Preferably, in the present embodiment, the back sheet 3 is made of beech board having a thickness of 0.5 mm.
