Abstract:
The present invention relates to a new plastic flooring that is assembled by concave portions and convex portions. The plastic flooring provides space between the concave portions and convex portions. The space absorbs the heat expansion of the plastic flooring such that the deformation of the plastic flooring is prevented. Also, the space stores an adhesive on a bottom floor such that crevices between the plastic flooring are prevented.
