Detailed Description

Exemplary embodiments that embody features and advantages of the present invention will be described in detail in the following description. It is to be understood that the invention is capable of other and different embodiments and its several details are capable of modification without departing from the scope of the invention, and that the description and drawings are to be regarded as illustrative in nature and not as restrictive.

Referring to fig. 1 to 5, the present embodiment provides a rail-type two-layer solid wood composite floor, which includes a surface layer 1 and a bottom layer 2. The surface layer 1 and the bottom layer 2 are closely connected in an adhesive mode, and the periphery of the bottom layer 2 is provided with a male tenon 3 and a female tenon 4. Wherein, the bottom layer 2 comprises two first laths 21 arranged in parallel and at intervals, and a plurality of second laths 22 arranged between the two first laths 21 and perpendicular to the first laths 21, and adjacent second laths 22 are tightly connected with each other in an adhesive manner. The inner sides of the two first laths 21 are provided with grooves. The two ends of each second lath 22 are provided with protrusions 23 matching with the grooves. The protrusion 23 is inserted into the recess and glue is applied to achieve a secure connection of the second panel 22 to the first panel 21.

Compared with the conventional fixing method only by glue bonding, the scheme fixes a plurality of second laths 22 between two first laths 21 by inserting the protrusions 23 on the second laths 22 into the grooves of the first laths 21 and matching with the glue bonding. Therefore, the wood floor is not easy to loosen after being trampled for many times, and the stability of the wood floor structure is greatly improved.

In particular, the facing layer 1 is primarily decorative and has various textures thereon. The surface of the surface layer 1 is coated with a wear-resistant paint layer. In the embodiment, the thickness of the surface layer 1 is 1.2-6.0 mm, and the material can be oak, birch, maple, black walnut, and other species with natural beautiful wood texture patterns.

The bottom layer 2 mainly serves as a support. As shown in fig. 3, the bottom layer 2 of the present embodiment includes two first laths 21 and eight second laths 22 disposed between the two first laths 21. The length of each second slat 22 is equal and less than the length of the first slat 21. In other embodiments, the number of second slats 22 may also be 3, 6, 9, etc.

As shown in fig. 1 and 2, two male tenons 3 and two female tenons 4 are arranged around the wood floor. One of the first strips 21 is provided with a male tenon 3, and the other opposite first strip 21 is provided with a female tenon 4. The second strip 22 at one end is provided with a male tenon 3, and the second strip 22 at the opposite end is provided with a female tenon 4. Preferably, the male tenon 3 and the female tenon 4 of the present embodiment are of a locking structure which is easy to install and can bear a larger pulling force. But in other embodiments a flat button type structure may be used. Particularly, after the male tenon 3 and the female tenon 4 are processed, a layer of waterproof paint can be sprayed on the surfaces of the male tenon and the female tenon to prevent the tenon from being wetted and rotten.

With continued reference to FIG. 5, to reduce the effect of torque, the grooves of this embodiment are formed at the same height as the opening of the mortise 4 on the first strip 21. Further, in order to further improve the stability of the internal structure, the distance from the upper shoulder to the lower shoulder at the position of the female tenon 4 is equal to the width of the groove, and the distance is the width W.

Referring again to fig. 5, in order to ensure the flatness and compactness of the wood floor, the thickness of the second strip 22 of the present embodiment is the same as that of the first strip 21, i.e., there is almost no gap inside after assembly. Wherein, the thickness of the first lath 21 and the second lath 22 is 12.0-16.4 mm. Through choosing large size thickness for use, can not only prevent the deformation of timber apron effectively, can let the user enjoy thick comfortable feel moreover, improve and use and experience. The width of the first lath 21 is 20-60 mm, the width of the second lath 22 is 20-60 mm, the width dimension is approximately the same as the width of the wood strip excess material in the actual production, the excess materials are reasonably utilized, and waste is avoided. The length of the first strip 21 can be selected according to the actual length of the wood floor, and is not limited herein. Similarly, the length of the second lath 22 can be selected according to the actual width of the wood floor, and is not limited herein.

Referring to fig. 6, the wood grain directions between adjacent second slats 22 are preferably perpendicular to each other. As shown in fig. 6, both first slats 21 are straight-grained. The wood grain directions of the eight second battens 22 are from bottom to top: transverse striation, longitudinal striation, transverse striation, and longitudinal striation. By adopting the criss-cross grain directions, the internal stress can be effectively eliminated, and the wood floor can be prevented from being tilted and deformed.

Referring to fig. 7, in another embodiment, both first slats 21 are feathered. The wood grain direction between the eight second slats 22 may also be: transverse striations, longitudinal striations, transverse striations, and transverse striations.

Referring to fig. 4 and 5 together, in order to further enhance the strength of the bottom layer 2, especially the position portion where a plurality of second slats 22 are provided, the rail-type two-layer engineered wood flooring of the present embodiment further includes a connecting rod (not shown), which is made of metal and has a long strip shape. Each of the second slats 22 is provided with a through hole 24, and the connecting rod passes through the through holes 24 to string the plurality of second slats 22 together.

While the present invention has been described with reference to the exemplary embodiments described above, it is understood that the terms used are words of description and illustration, rather than words of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
