This application relates to floorings, and more particularly to a floorboard with a coupling structure.
As a covering material for both interior and exterior applications in construction, flooring possesses significant functional and aesthetic value. The spliced flooring is formed by multiple floorboards interconnected utilizing a locking structure or a mortise and tenon joint structure. The spliced flooring is characterized by easy assembly, disassembly and replacement, and absence of glue. During the manufacture of the existing spliced floorboards, the mortise is usually processed to have a flat-straight edge, but such mortise fails to ensure a stable and firm connection. As a result, the connection between floorboards will become loosened over time, and the gap will become wider and wider, thus affecting the service life of the flooring.
In view of this, it is necessary to provide a floorboard that can improve the connection strength and stability.
A floorboard, comprising:
In some embodiments, the first tenon comprises a first side portion, a first bottom structure and a second side portion sequentially connected;
In some embodiments, the first mortise comprises a first inclined surface, a first bottom surface and a second inclined surface sequentially connected;
In some embodiments, the first bottom structure comprises a first bottom portion and a second bottom portion; an end of the first bottom portion is connected to an end of the first side portion; and the first bottom portion is arranged horizontally; and
In some embodiments, the second tenon comprises a third side portion, a second bottom structure and a fourth side portion sequentially connected;
In some embodiments, the third side portion comprises a first straight section, a second inclined section and a second straight section;
In some embodiments, the second bottom structure comprises a third inclined section, a third straight section and a fourth inclined section;
In some embodiments, the fourth side portion comprises a fifth inclined section and a sixth inclined section connected with each other;
In some embodiments, the second mortise comprises a first straight surface, a third inclined surface, a second straight surface, a fourth inclined surface, a third straight surface, a curved surface, a fifth inclined surface and a sixth inclined surface sequentially connected;
In some embodiments, the third straight section comprises a first sub-section and a second sub-section;
In some embodiments, a third mortise is provided between the first tenon and the second tenon; a third tenon is provided between the first mortise and the second mortise; and the third tenon is configured to fit the third mortise;
In some embodiments, the second coupling structure further comprises a seventh inclined surface; the seventh inclined surface is configured to incline downward from an end of the second inclined surface away from the first bottom surface in the direction away from the first mortise; and the seventh inclined surface is connected to an end of the first straight surface away from the third inclined surface;
Regarding the floorboard provided herein, two opposite sides of the main body are respectively provided with the first coupling structure and the second coupling structure. The first coupling structure includes the first tenon and the second tenon, both of which are configured to partially incline relative to the main body. When two floorboards are coupled, the first tenon of one of the two floorboards is inserted into the first mortise of the other of the two floorboards, and the second tenon of one of the two floorboards is inserted into the second mortise of the other of the two floorboards. The first tenon and the second tenon are configured to partially incline relative to the main body to generate force components in the first and second directions when two floorboards are coupled. The floorboard provided herein can significantly improve the coupling strength stability and reliability.

Specifically, a vertical distance between the rightmost point of the first tenon 4 and the fifth straight surface 28 is at most 12 mm, preferably at most 10 mm, and more preferably at most 8 mm.
In this application, through the engagement of the first tenon 4 with the first mortise 6, the engagement of the second tenon 5 with the second mortise 7, the engagement of the third tenon 9 with the third mortise 8, and the engagement of the fourth mortise 26 with the fourth tenon 35, the cooperation of multiple tenons and mortises can enhance the strength at the joints and improve the floorboard connections stability. The existence of multiple tenons enables a more uniform distribution of forces, reduces the stress concentration at a certain location, and mitigates the risks of material deformation and damage to the floorboard. During the interlocking of the tenons and mortises, multiple contact surfaces abut against each other. When subjected to horizontal or vertical pulling or compressive forces, these contact surfaces contribute to the stable floorboard connection. At the same time, the multiple contact surfaces share the applied load to improve the service life and reliability of the first coupling structure 2 and the second coupling structure 3.
An assembly process of floorboards of the present disclosure is performed through the following steps. Firstly, the first tenon 4 is inserted into the first mortise 6. Then, a force is applied on the second tenon 5 to press the floorboard down, causing the second tenon 5 to engage with the second mortise 7. Simultaneously, the third tenon 9 is engaged with the third mortise 8, and the fourth tenon 35 is engaged with the fourth mortise 26. At this point, the first connecting surface 23 of the first coupling structure 2 of one of the two floorboards closely abuts the second connecting surface 39 of the second coupling structure 3 of the other of the two floorboards. Meanwhile, the seventh straight surface 37 of one of the two floorboards closely abuts the fifth straight surface 28 of the other of the two floorboards.
Described above are merely preferred embodiments of the present disclosure, and are not intended to limit the scope of the present disclosure. It should be understood that various modifications, changes and replacements made by those skilled in the art without departing from the spirit of the disclosure shall fall within the scope of the present disclosure defined by the appended claims.
