1. A floor board (10), which has a top side (2a), a bottom side (2b) and at least four side surfaces (3, 4, 5, 6), wherein respectively two opposite-lying side surfaces (3, 4, 5, 6) have connection geometries (A, B) corresponding to each other made of plastic and wherein the floor board (10) consists of a base plate (1), characterized in that
the first connection geometry (A) is provided along two abutting side surfaces (3, 4) and has a groove (11) which is open toward the bottom and is bordered by a lip (12) toward the outside, and the groove (11) has an undercut (16) along its walls, and the second connection geometry (B) is provided along the abutting side surfaces (5, 6) and has a groove (13) which is open toward the top and is bordered by a lip (14) toward the outside, and the groove (13) has an undercut (19) along its walls, wherein the shape and dimension of the first connection geometry (A) is complementary to the shape and dimension of the second connection geometry (B), wherein the lip (12) of the first connection geometry (A) and the lip (14) of the second connection geometry (B) each have at least one slot (22) at least in sections. |
