FIELD: building units, particularly floors. SUBSTANCE: floor tile comprises end profiles created on at least two opposing edges thereof. Profiles are formed as modified matching connections for joining of adjacent floor tiles. Each connection has corresponding configuration including one slot and one joggle such that joggle of the first tile edge and slot of the second tile edge extend at an angle upwards from tile lower surface. End profiles are formed directly in tile substrate such that slot of the first tile is located directly above joggle thereof. Slot lower wall is inclined towards slot rear end and slot inclination angle is equal to that of joggle. Slot upper wall is parallel to tile plane. Joggle shape of the second tile corresponds to slot shape of the first tile due to forming joggle upper surface in parallel to tile plane and joggle lower surfaces orienting obliquely to joggle end. EFFECT: increased buckling resistance. 25 cl, 10 dwg |
