  • the jumping effect of the prominence 12 of the first floor board 30 is due to the fact that when an imaginary rectilinear line is drawn parallel to the direction of the plane of the first and the second floor boards 30 and 40 (as indicated by the dotted line of FIG. 3 ), the inclined upper sides of the protrusion 11 and the groove 21 with respect to the imaginary rectilinear line has an inclination ⁇ of 10-30°.

Furthermore, with the sectional flooring according to the present embodiment, when the floor boards are distorted due to the ambient temperature or humidity, the stress generated at the coupling structure with the protrusion 11 and the groove 21 is diffused around the stopper receiving indentation 13 ′, thereby minimizing the distortion of the coupling structure.
