PURPOSE: A floor panel with a tooth structure is provided to minimize gaps between floor panels occurred due to a vertical load and a temperature difference. CONSTITUTION: A floor panel(P) with a tooth structure comprises a lower concave unit(1), a lower convex unit(2), an upper convex unit(11), an upper concave unit(12), a lower toothed coupling unit(3), and an upper toothed coupling unit(13). The lower concave and convex units are formed on one surface of the floor panel to be lower than the floor panel. The upper convex and concave units are formed on the other surface of the floor panel. The lower toothed coupling unit is formed on the outer surface of the lower convex unit, and the upper toothed coupling unit is formed on the outer surface of the upper concave unit. |
